© 2020 Elsevier Ltd Schools have closed worldwide as part of measures to prevent SARS-CoV-2 transmission but are beginning to reopen in some countries. Various measures are being pursued to minimise transmission but existing guidance has not developed a comprehensive framework or theory of change. We present a framework informed by the occupational health hierarchy of control and a theory of change informed by realist approaches. We present measures focused on elimination, substitution, engineering, administration, education and personal protective equipment. We theorise that such measures offer a means of disrupting SARS-CoV-2 transmission via routes involving fomites, faeco-oral routes, droplets and aerosols.

This study analyses large-scale online data to examine the characteristics of a national commercial sex network of off-street female sex workers and their male clients to identify implications for public health policy and practice. We collected sexual contact information from the largest online community dedicated to reviewing sex workers’ services in the UK. We built the sexual network using reviews reported between January 2014 and December 2017. We then quantified network parameters using social network analysis measures. The network is composed of 6477 vertices with 59% of them concentred in a giant component clustered around London and Milton Keynes. We found minimal disassortative mixing by degree between sex workers and their clients, and that a few clients and sex workers are highly connected whilst the majority only have one or few sexual contacts. Finally, our simulation models suggested that prevention strategies targeting both sex workers and clients with high centrality scores are the most effective in reducing network connectedness and average closeness centrality scores, thus limiting the transmission of STIs.

Despite new, effective biomedical technologies to prevent the transmission of HIV, social and structural factors still impact the opportunity for gay, bisexual and other men who have sex with men (GBMSM) to access safe sexual health services. Within this paper we describe findings of a pilot analysis that seeks to identify relationships between country level homophobia, individual-level sexualised drug use and key sexual health protective behaviours in a sample of HIV negative men from 45 countries recruited via a large online survey. Responses to questions relating to HIV and STI testing history, use of pre-exposure prophylaxis (PrEP), post-exposure prophylaxis (PEP) and engagement in sexualised drug use were treated as dependent variables within generalised linear mixed-effects model with logit link analysis, with country level homophobia (drawn from a recently published international index) operating as the dependent variable. In total, data from 9,356 respondents were included for analysis. Overall, uptake of behaviours known to be protective of sexual health overall was significantly lower in countries with high levels of homophobia. This paper is unique in linking a robust measure of country-level homophobia to engagement in health protective behaviours on a large-scale, multi-country level basis.

BACKGROUND: Despite recent improvements in the burden of cardiovascular disease (CVD) in the UK, deaths from CVD are relatively high compared with other high-income countries. An estimated 7 million people in the UK are living with CVD, and the healthcare cost is approximately £11 billion annually. In more than 90% of cases, the risk of a first heart attack is thought to be related to modifiable risk factors including smoking, poor diet, lipidemia, high blood pressure, inactivity, obesity and excess alcohol consumption. The aim of the study is to synthesise evidence for the comparative effectiveness and cost-effectiveness of different interventions for the primary prevention of CVD. METHODS: We will systematically search databases (for example, MEDLINE (Ovid), Embase (Ovid), Cochrane Library) and the reference lists of previous systematic reviews for randomised controlled trials that assess the effectiveness and cost-effectiveness of any form of intervention aimed at adult populations for the primary prevention of CVD, including but not limited to lipid lowering medications, blood pressure lowering medications, antiplatelet agents, nutritional supplements, dietary interventions, health promotion programmes, physical activity interventions or structural and policy interventions. Interventions may or may not be targeted at high-risk groups. Publications from any year will be considered for inclusion. The primary outcome will be all cause mortality. Secondary outcomes will be cardiovascular diseases related mortality, major cardiovascular events, coronary heart disease, incremental costs per quality-adjusted life years gained. If data permits, we will use network meta-analysis to compare and rank effectiveness of different interventions, and test effect modification of intervention effectiveness using subgroup analyses and meta-regression analyses. DISCUSSION: the results will be important for policymakers when making decisions between multiple possible alternative strategies to prevent CVD. Compared to results from existing multiple separate pairwise meta-analyses, this overarching synthesis of all relevant work will enhance decision-making. The findings will be crucial to inform evidence-based priorities and guidelines for policies and planning prevention strategies of CVD. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019123940.

Increasing recognition of the difficulties women and adolescent girls face during menstruation has the prompted rapid implementation of menstrual health programmes and policies. Yet, there remains limited understanding of the influence of these interventions on individuals' menstrual experiences. We systematically reviewed and synthesised qualitative studies of participant experiences of menstrual health interventions. Included studies were undertaken in 6 countries (India, Uganda, Kenya, Ethiopia, Zimbabwe, South Africa) and involved over 900 participants. Interventions focused on menstrual product or education provision. Only 6 of the 12 included studies were rated as high or medium trustworthiness. Exposure to new menstrual products led to changes in women's and girls' expectations of what a menstrual material should offer, with recipients highly valuing reduced fears of leakage and improved freedom of movement. After learning how to use new products or receiving educational materials, women and girls reported feeling more empowered and aware of the physiological process of menstruation, and in some cases wanted to share this knowledge with others in their communities. For each intervention, the process of introduction, trial and error, and acceptance of the new technologies or information was influenced by the sociocultural environment including parents, peers and teachers.

Adolescent dating and relationship violence is associated with health harms and is an important topic for sex education. School-based interventions addressing this have been effective in the USA, but schools in England confront pressures that might hinder implementation. We assessed the feasibility of, and contextual enablers/barriers to implementing Project Respect, a whole-school intervention. We conducted a pilot trial with process evaluation in six English secondary schools. Intervention comprised: training; policy-review; mapping and patrolling ‘hotspots’; parent information; help-seeking app; and a curriculum (including student-led campaigns) targeting dating violence. Process evaluation included assessments of fidelity and interviews with the trainer and school staff. Schools delivered training and lessons partially or completely and made parent and app information available. Two schools conducted policy reviews; none patrolled hotspots or implemented campaigns. Implementation was strengthened where staff saw dating violence as a priority. Delivery was undermined where staff were insufficiently involved, lacked time for planning or struggled to timetable lessons, and where new school challenges undermined engagement. School-based health interventions must work to build staff buy-in and ensure they do not overburden schools. Dating and relationship violence might best be addressed in this context as a broader aspect of sex education.

AIMS AND OBJECTIVES: to evaluate the process of implementing an oral care intervention in nursing homes in a Danish municipality. BACKGROUND: Older people with aged natural dentition require preventive and curative oral health care. An intervention based on principles of situated learning was implemented to establish closer cooperation between dental and nursing staff in nursing homes, leading to improved oral hygiene in nursing home residents. DESIGN: an embedded multiple-case study combined with principles of realist evaluation unfolded in three phases: Formulation of initial programme theory, Testing and Refining the programme theory. The COREQ checklist is followed in reporting. METHODS: Observations, six group interviews and 22 face-to-face interviews with dentists, dental practitioners, nursing home managers, care professionals and residents were conducted in three nursing homes (n = 41). RESULTS: Three main outcomes of a programme theory were identified, relating to (a) residents, in the form of new oral care routines; (b) interdisciplinary working, in the form of professional pride in performing sufficient oral care; (c) organisational level changes, in the form of increased interdisciplinary knowledge sharing. The overarching supportive mechanisms were the creation of relationships between residents, dental practitioners and care professionals as well as nursing home management taking responsibility for structure, planning and knowledge sharing. CONCLUSION: the situated learning perspective supported residents and care professionals' competencies in performing sufficient oral care. The shared oral care intervention supports an individual and multidisciplinary assessment of nursing home residents' ability to self-care concerning oral care. Contextual factors, supportive and restraining mechanisms influence the intervention's success. RELEVANCE TO CLINICAL PRACTICE: Understanding the complexity within interdisciplinary cooperation in primary nursing and unravelling the necessary properties to enhance nursing home residents' oral health care are areas of improvement for care service in nursing homes.

BACKGROUND: the lack of established measurement tools in the study of menstrual health and hygiene has been a significant limitation of quantitative studies to date. However, there has been limited exploration of existing measurement to identify avenues for improvement. METHODS: We undertook two linked systematic reviews of (1) trials of menstrual health interventions and their nested studies in low- and middle-income countries, (2) studies developing or validating measures of menstrual experiences from any location. Systematic searching was undertaken in 12 databases, together with handsearching. We iteratively grouped and audited concepts measured across included studies and extracted and compared measures of each concept. RESULTS: a total of 23 trials, 9 nested studies and 22 measure development studies were included. Trials measured a range of outcomes including menstrual knowledge, attitudes, and practices, school absenteeism, and health. Most measure validation studies focused on assessing attitudes towards menstruation, while a group of five studies assessed the accuracy of women's recall of their menstrual characteristics such as timing and cycle length. Measures of menstrual knowledge, attitudes, beliefs and restrictions were inconsistent and frequently overlapped. No two studies measured the same menstrual or hygiene practices, with 44 different practices assessed. This audit provides a summary of current measures and extant efforts to pilot or test their performance. CONCLUSIONS: Inconsistencies in both the definition and operationalisation of concepts measured in menstrual health and hygiene research should be addressed. To improve measurement, authors should clearly define the constructs they aim to measure and outline how these were operationalised for measurement. Results of this audit indicate the need for the development and validation of new measures, and the evaluation of the performance of existing measures across contexts. In particular, the definition and measurement of menstrual practices, knowledge, attitudes, norms and restrictions should be addressed. REVIEW PROTOCOL REGISTRATION: CRD42018089884.

A recent increase in the development of online parent programs calls for the need to understand how effective these strategies are for improving children's mental health. We meta-analyzed the effects of online parent programs on children's behavioral problems. Moreover, we explored the combinations of program components to yield stronger program effects. Medline, PsycINFO, Web of Science, and the Cochrane Library were searched. We included peer-reviewed randomized studies evaluating the effect of an online parent program. Effect sizes (Hedges' g) were calculated from post intervention means and standard deviations. We used Qualitative Comparative Analysis (QCA) to identify pathways to effectiveness and individual content and delivery components that seem sufficient or necessary for yielding high effectiveness. of 2941 articles, 12 articles with a total of 2025 participants met the inclusion criteria. Online parent programs have significant effects on children's behavioral problems (g =   - 0.32; 95% CI, - 0.47 to - 0.17), emotional problems (g =  - 0.22; 95% CI, - 0.31 to - 0.13), and parental mental health problems (g =  - 0.30; 95% CI, - 0.42 to - 0.17). In the QCA, sending parents reminders to work on the program was the only one sufficient component. In conclusion, online support programs reduce children's behavioral and emotional problems and improve parental mental health. Sending parents reminders to work on the program seems to contribute to high effectiveness. Review Registration This study was registered with PROSPERO, number CRD42017080051.

BACKGROUND: Currently, the strongest evidence for preventing violence against children lies with social learning theory-based parenting interventions. An increasing number of experimental studies on such interventions have been conducted in low- and middle-income countries (LMICs) in East and Southeast Asia. OBJECTIVE: to conduct a systematic review and meta-analysis on the effectiveness of parenting interventions in preventing violence against children. PARTICIPANTS AND SETTING: Parents and primary caregivers living in LMICs in East and Southeast Asia. METHODS: Eleven studies were retrieved through electronic databases, expert contacts, and the reference sections of previous reviews. Studies were appraised for risk of bias and effect estimates pooled using random effects multilevel meta-analysis. RESULTS: Forty-four effect estimates were meta-analyzed based on five outcome category models, finding a small effect on abusive, harsh, or negative parenting (n = 3, d = -0.42, 95 % CI [- 0.81, -0.02], p 

BACKGROUND: Gambling opportunities are increasingly available and acceptable to many adolescents. Adolescent problem gambling has been associated with poor outcomes, such as lower reported physical and mental health. While much research has focussed on 'problem' gambling, analysing the distribution and determinants of experimentation with gambling is important in order to understand its normalization and population level consequences. This study describes the distribution of inequalities and socioemotional harms associated with adolescent gambling. METHODS: Data were drawn from a subsample of students (N = 37 363) who completed gambling questions as part of the 2017 School Health Research Network Student Health and Wellbeing Survey, representing 193 secondary schools in Wales. Using imputations, we estimated a series of single-predictor and multi-predictor regressions for count of gambling behaviours, any gambling in the past 12 months and socioemotional harms of gambling. RESULTS: Approximately two-fifths (41.0%) of respondents reported gambling in the past 12 months, of whom 16.2% reported feeling bad as a result of their own gambling. We found significant sex differences in gambling, with boys gambling more frequently than girls. Adolescents from more affluent families reported a higher count of gambling behaviours and socioemotional harms, although paradoxically, increasing affluence was also associated with lower prevalence of gambling in the last year. Non-White British ethnicities and students who felt less connected to school were more likely to engage in gambling and experience socioemotional harms. CONCLUSIONS: Our findings provide important new insights regarding risk factors in adolescence associated with gambling behaviours and socioemotional harms.

INTRODUCTION: As adolescents transition from childhood to adulthood, they experience major physical, social and psychological changes, and are at heightened risk for developing mental health conditions and engaging in health-related risk behaviours. For adolescents living with HIV (ALHIV), these risks may be even more pronounced. Research shows that this population may face additional mental health challenges related to the biological impact of the disease and its treatment, the psychosocial burdens of living with HIV and HIV-related social and environmental stressors. DISCUSSION: Psychosocial interventions delivered to adolescents can promote positive mental health, prevent mental health problems and strengthen young people's capacity to navigate challenges and protect themselves from risk. It is likely that these interventions can also benefit at-risk populations, such as ALHIV, yet there is little research on this. There is an urgent need for more research evaluating the effects of interventions designed to improve the mental health of ALHIV. We highlight four priorities moving forward. These include: generating more evidence about preventive mental health interventions for ALHIV; including mental health outcomes in research on psychosocial interventions for ALHIV; conducting intervention research that is sensitive to differences among ALHIV populations and involving adolescents in intervention design and testing. CONCLUSIONS: More robust research on promotive and preventive mental health interventions is needed for ALHIV. Programmes should be informed by adolescent priorities and preferences and responsive to the specific needs of these groups.

BACKGROUND: Pregnancy and parenthood are known to be high-risk times for mental health. However, less is known about the mental health of pregnant adolescents or adolescent parents. Despite the substantial literature on the risks associated with adolescent pregnancy, there is limited evidence on best practices for preventing poor mental health in this vulnerable group. This systematic review therefore aimed to identify whether psychosocial interventions can effectively promote positive mental health and prevent mental health conditions in pregnant and parenting adolescents. METHODS: We used the standardized systematic review methodology based on the process outlined in the World Health Organization's Handbook for Guidelines Development. This review focused on randomized controlled trials of preventive psychosocial interventions to promote the mental health of pregnant and parenting adolescents, as compared to treatment as usual. We searched PubMed/Medline, PsycINFO, ERIC, EMBASE and ASSIA databases, as well as reference lists of relevant articles, grey literature, and consultation with experts in the field. GRADE was used to assess the quality of evidence. RESULTS: We included 17 eligible studies (n = 3245 participants). Interventions had small to moderate, beneficial effects on positive mental health (SMD = 0.35, very low quality evidence), and moderate beneficial effects on school attendance (SMD = 0.64, high quality evidence). There was limited evidence for the effectiveness of psychosocial interventions on mental health disorders including depression and anxiety, substance use, risky sexual and reproductive health behaviors, adherence to antenatal and postnatal care, and parenting skills. There were no available data for outcomes on self-harm and suicide; aggressive, disruptive, and oppositional behaviors; or exposure to intimate partner violence. Only two studies included adolescent fathers. No studies were based in low- or middle-income countries. CONCLUSION: Despite the encouraging findings in terms of effects on positive mental health and school attendance outcomes, there is a critical evidence gap related to the effectiveness of psychosocial interventions for improving mental health, preventing disorders, self-harm, and other risk behaviors among pregnant and parenting adolescents. There is an urgent need to adapt and design new psychosocial interventions that can be pilot-tested and scaled with pregnant adolescents and adolescent parents and their extended networks, particularly in low-income settings.

This study evaluated the Grassroot Project, a middle school sexual health promotion program in Washington, DC that uses university-level athlete role models and sports-based games. Seven schools were allocated to immediate (n = 160) or delayed intervention (n = 166). Students were tested before and immediately after the intervention on attitudes and self-efficacy to avoid sexual risk, intentions to avoid or engage in sexual intercourse, HIV stigma, and endorsement of violent behaviors. There was no evidence of differences between groups; however, the intervention has promise in respect of key outcome domains. This research justifies future longitudinal evaluation to assess behavioral and biomedical outcomes.

Interventions that train parents to share picture books with children are seen as a strategy for supporting child language development. We conducted meta-analyses using robust variance estimation modeling on results from 19 RCTs (Ntotal  = 2,594; Mchildage  = 1-6 years). Overall, book-sharing interventions had a small sized effect on both expressive language (d = 0.41) and receptive language (d = 0.26). They had a large effect on caregiver book-sharing competence (d = 1.01). The impact of the intervention on child language was moderated by intervention dosage, with lower dosage associated with a minimal impact. Child age and caregiver education level were unrelated to child outcome. This review and meta-analysis confirms the promise of book-sharing interventions for enhancing and accelerating child language development.

© 2020 the Authors. British Educational Research Journal published by John Wiley. &. Sons Ltd on behalf of British Educational Research Association Young people's wellbeing is often lowest where they assume a relatively low position within their school's socioeconomic hierarchy, for example, among poorer children attending more affluent schools. Transition to secondary school is a period during which young people typically enter an environment which is more socioeconomically diverse than their primary school. Young people joining a school with a higher socioeconomic status intake relative to their primary school may assume a relatively lowered position within their school’s socioeconomic hierarchy, experiencing a detriment to their wellbeing as a consequence. This article draws on data from 45,055 pupils in Years 7 and 8, from 193 secondary schools in Wales, who completed the 2017 Student Health Research Network (SHRN) Student Health and Wellbeing (SHW) survey. Pupils reported which primary school they previously attended, and survey data on wellbeing were linked to publicly available data on the free school meal entitlement of schools attended. In cross-classified linear mixed-effects models, with primary and secondary school as levels, mental wellbeing varied significantly according to both primary and secondary school attended. A higher school-level deprivation was associated with worse mental wellbeing in both cases. Mental wellbeing was significantly predicted by the relative affluence of a child's primary and secondary school, with movement to a secondary school of higher overall socioeconomic status associated with lowered wellbeing. These findings highlight transition to secondary school as a key point in which socioeconomic inequality in wellbeing may widen, and thus as an important focal point for intervention to reduce health inequalities.

Importance: the degree to which children and adolescents are infected by and transmit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unclear. The role of children and adolescents in transmission of SARS-CoV-2 is dependent on susceptibility, symptoms, viral load, social contact patterns, and behavior. Objective: to systematically review the susceptibility to and transmission of SARS-CoV-2 among children and adolescents compared with adults. Data Sources: PubMed and medRxiv were searched from database inception to July 28, 2020, and a total of 13926 studies were identified, with additional studies identified through hand searching of cited references and professional contacts. Study Selection: Studies that provided data on the prevalence of SARS-CoV-2 in children and adolescents (younger than 20 years) compared with adults (20 years and older) derived from contact tracing or population screening were included. Single-household studies were excluded. Data Extraction and Synthesis: PRISMA guidelines for abstracting data were followed, which was performed independently by 2 reviewers. Quality was assessed using a critical appraisal checklist for prevalence studies. Random-effects meta-analysis was undertaken. Main Outcomes and Measures: Secondary infection rate (contact-tracing studies) or prevalence or seroprevalence (population screening studies) among children and adolescents compared with adults. Results: a total of 32 studies comprising 41640 children and adolescents and 268945 adults met inclusion criteria, including 18 contact-tracing studies and 14 population screening studies. The pooled odds ratio of being an infected contact in children compared with adults was 0.56 (95% CI, 0.37-0.85), with substantial heterogeneity (I2= 94.6%). Three school-based contact-tracing studies found minimal transmission from child or teacher index cases. Findings from population screening studies were heterogenous and were not suitable for meta-analysis. Most studies were consistent with lower seroprevalence in children compared with adults, although seroprevalence in adolescents appeared similar to adults. Conclusions and Relevance: in this meta-analysis, there is preliminary evidence that children and adolescents have lower susceptibility to SARS-CoV-2, with an odds ratio of 0.56 for being an infected contact compared with adults. There is weak evidence that children and adolescents play a lesser role than adults in transmission of SARS-CoV-2 at a population level. This study provides no information on the infectivity of children.

BACKGROUND: Rapid infant weight gain (RIWG) is strongly related to childhood overweight and obesity, and prevention of RIWG is an approach to early years obesity prevention. This systematic review aimed to explore effectiveness, deliverers' and recipients' experiences of involvement, and key intervention components and processes of such prevention activities. METHODS: Key databases and websites were searched systematically for quantitative and qualitative studies covering intervention effectiveness, experiences with intervention involvement or process outcomes. After duplicate screening and quality assessment, papers were analyzed through narrative synthesis, thematic synthesis and intervention component analysis. RESULTS: Seven quantitative and seven qualitative studies were eligible for inclusion. Most intervention studies reported small, but significant results on infant weight gain. More significant results were measured on weight gain during the first compared with the second year of life. A weak evidence base made elaboration of the relationship between intervention effectiveness and content challenging. Home-delivered interventions may be more relevant for parents. Contextual factors, such as social norms, beliefs and professional identity should be considered during intervention development. Stakeholder involvement can be key to increase intervention acceptability and feasibility. CONCLUSIONS: the field of RIWG prevention is new and evolving, but more research is needed before further conclusions about intervention effectiveness and intervention content can be drawn. Future interventions should take parents, health professionals and other contextual needs into account to improve chances of success. More research on long-term effects on overweight and obesity is needed.

BACKGROUND: This study reports on qualitative research conducted within a randomised controlled trial to explore possible intervention mechanisms. It focuses on the 'Learning Together' whole-school intervention delivered in secondary schools in England from 2014 to 2017 aiming to prevent bullying and aggression and improve student health. Intervention schools received staff training in restorative practice, a social and emotional learning curriculum, and an external facilitator and manual to convene and run a student/staff action group tasked with coordinating the intervention, focusing this on local needs. METHODS: Informed by realist approaches to evaluation, we analysed qualitative data to explore intervention mechanisms and how these might interact with school contexts to generate outcomes. Qualitative analysis drew on 45 interviews and 21 focus groups across three case-study schools and employed thematic content analysis to explore how intervention resources were taken up and used by local actors, how participants described the intervention mechanisms that then ensued, and how these might have generated beneficial outcomes. RESULTS: the thematic content analysis identified three social mechanisms that recurred in participant accounts: (1) building student commitment to the school community, (2) building healthy relationships by modelling and teaching pro-social skills, and (3) de-escalating bullying and aggression and enabling re-integration within the school community. CONCLUSIONS: Our analysis provides in-depth exploration of possible mechanisms and the contextual contingencies associated with these, allowing refinement of the initial intervention theory of change.

The UK National Institute for Health and Care Excellence (NICE) considered evidence for voretigene neparvovec (VN; Luxturna®) for the treatment of RPE65-mediated inherited retinal dystrophies (IRD) within its highly specialised technology programme. This paper summarises the evidence provided by the company; the appraisal of the evidence by the Peninsula Technology Appraisal Group, who were commissioned to act as the independent evidence review group (ERG); and the development of the NICE guidance by the appraisal committee. The evidence presented by the company highlighted the significant lifelong burden of IRD for patients and carers. Evidence to support the effectiveness of VN was lacking, but the available evidence showed a modest, sustained improvement across a variety of vision-related outcomes. While patients would remain visually impaired, the committee considered that VN would prevent further deterioration in vision. The modelling approach used by the company had a number of limitations and relied heavily upon a large volume of clinical expert input to produce cost-effectiveness estimates with large uncertainty around long-term effectiveness. The ERG's main concerns revolved around these long-term outcomes and the plausibility of utility values. The NICE committee were convinced that the clinical benefits of VN were important and an appropriate use of national health service resources within a specialised service. The committee concluded that a high unmet need existed in patients with RPE65-mediated IRD and that VN represents a step change in the management of this condition.

There is increasing interest in what evidence is needed to inform decisions about transporting interventions evaluated as effective to new settings. There has been less attention to how local decision-makers decide whether to implement such interventions immediately or subject to further evaluation. Using the example of school-based social and emotional learning, we consider this drawing on realist methods. We suggest decisions need to assess existing evaluations not merely in terms of whether the intervention was effective but also: how the intervention was implemented and what contextual factors affected this (drawing on process evaluation); and for whom the intervention was effective and through what mechanisms (drawing on mediation, moderation and qualitative comparative analyses from primary studies and/or systematic reviews). We contribute new insights to local needs assessments, suggesting that these should assess: the potential, capability, contribution and capacity present in the new setting for implementation; and whether similar 'aetiological mechanisms' underlie adverse outcomes locally as in previous evaluations. We recommend that where there is uncertainty concerning whether an intervention can feasibly be implemented this indicates the need for piloting of implementation. Where there is uncertainty concerning whether implementation of the intervention will trigger intended mechanisms, this suggests the need for a new effectiveness trial. Where there is uncertainty concerning whether intervention mechanisms, even if triggered, will generate the intended outcomes, this suggests that decision-makers may need to look to other types of intervention as being needed for their setting instead.

CONTEXT: Although adolescent mental health interventions are widely implemented, little consensus exists about elements comprising successful models. OBJECTIVE: We aimed to identify effective program components of interventions to promote mental health and prevent mental disorders and risk behaviors during adolescence and to match these components across these key health outcomes to inform future multicomponent intervention development. DATA SOURCES: a total of 14 600 records were identified, and 158 studies were included. STUDY SELECTION: Studies included universally delivered psychosocial interventions administered to adolescents ages 10 to 19. We included studies published between 2000 and 2018, using PubMed, Medline, PsycINFO, Scopus, Embase, and Applied Social Sciences Index Abstracts databases. We included randomized controlled, cluster randomized controlled, factorial, and crossover trials. Outcomes included positive mental health, depressive and anxious symptomatology, violence perpetration and bullying, and alcohol and other substance use. DATA EXTRACTION: Data were extracted by 3 researchers who identified core components and relevant outcomes. Interventions were separated by modality; data were analyzed by using a robust variance estimation meta-analysis model, and we estimated a series of single-predictor meta-regression models using random effects. RESULTS: Universally delivered interventions can improve adolescent mental health and reduce risk behavior. of 7 components with consistent signals of effectiveness, 3 had significant effects over multiple outcomes (interpersonal skills, emotional regulation, and alcohol and drug education). LIMITATIONS: Most included studies were from high-income settings, limiting the applicability of these findings to low- and middle-income countries. Our sample included only trials. CONCLUSIONS: Three program components emerged as consistently effective across different outcomes, providing a basis for developing future multioutcome intervention programs.

BACKGROUND: Smoking remains a major public health concern. School-based social networks influence uptake of smoking among peers. During the past two decades, the UK macro-systemic context within which schools are nested and interact with has changed, with anti-smoking norms having become set at a more macro-systemic level. Whilst the overall prevalence of smoking in the UK has decreased, inequality has prevailed. It is plausible that the influence of school-based social networks on smoking uptake may vary according to socioeconomic status. Therefore, this study aims to understand how social influence on smoking among adolescents has changed in line with variance within and between contexts according to time and geography. METHODS: the following databases will be searched: Medline, PsycINFO, Embase, Applied Social Sciences Index and Abstracts (ASSIA), British Education Index, Sociological abstracts, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Education Resources Information Center (ERIC) and Scopus. Additional searches will include reference checking of key papers, citation tracking, word of mouth and grey literature searches. The search strategies will incorporate terms relating to smoking, adolescents, schools, peers, network analysis and qualitative research. Titles and abstracts and full texts will be independently screened and assessed for quality by at least two researchers. Included studies will be assessed for quality, and data will be extracted for synthesis, including participant characteristics, setting and tobacco control context, study design and methods, analysis and results and conclusions. Quantitative findings will be narratively synthesised, whilst a lines of argument synthesis combined with refutational analysis will be employed to synthesise qualitative data. Both sets of findings will be charted on a timeline to add context to network findings and obtain an enhanced understanding of changes over time. DISCUSSION: This protocol is for a mixed methods synthesis of both social network findings, to investigate social structures and qualitative studies, to elicit contextual information. The review will synthesise changes in the context of social influence on adolescent smoking over time and geographically. As context is increasingly recognised as a key source of complexity, this enhanced understanding will help to inform future interventions targeting smoking through social influence. This will help to enhance their relevance to context, subsequent effectiveness and targeting of inequalities. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019137358.

Children vary in the extent to which they benefit from parenting programs for conduct problems. How does parental mental health change if children benefit less or more? We assessed whether changes in conduct problems and maternal depressive symptoms co-occur following participation in the Incredible Years parenting program. We integrated individual participant data from 10 randomized trials (N = 1280; children aged 2-10 years) and distinguished latent classes based on families' baseline and post-test conduct problems and maternal depressive symptoms, using repeated measures latent class analysis (RMLCA) and latent transition analysis (LTA). Classes differed mainly in severity of conduct problems and depression (RMLCA; 4 classes). Conduct problems reduced in all classes. Depressive symptoms did not change in most classes, except in a class of families where conduct problems and depression were particularly severe. Incredible Years led to a greater likelihood of families with particularly severe conduct problems and depression moving to a class with mild problems (LTA; 3 classes). Our findings suggest that for the majority of families, children's conduct problems reduce, but maternal depressive symptoms do not, suggesting relative independence, with the exception of families with severe depression and severe conduct problems where changes for the better do co-occur.

BACKGROUND: a review of therapies for advanced cancers licenced by the EMA between 2009 and 2013 concluded that for more than half of these drugs there was little evidence of overall survival or quality of life benefit. Recent years have witnessed a growing number of licensed second-line pharmacotherapies for advanced/metastatic non-small cell lung cancer (NSCLC). With the aim of gauging patient survival benefit, we conducted a systematic review of randomised controlled trials (RCT) and compared survival outcomes from available licensed treatments for patients with advanced/metastatic NSCLC. METHODS: RCTs of second/third line treatments in participants with advanced/metastatic NSCLC and negative/low expression of Anaplastic Lymphoma Kinase (ALK) and of Epidermal Growth Factor Receptor (EGFR) were included. We searched electronic databases (MEDLINE; EMBASE; Web of Science) from January, 2000 up to July, 2017. Two or more independent reviewers screened bibliographic records, extracted data, and assessed risk of bias of studies. Published Kaplan Meier plots for OS and PFS along with restricted-mean-survival methods and parametric modelling were used to estimate the survival outcomes as mean number of months of survival. Network meta-analysis was undertaken to rank interventions and to make indirect comparisons. RESULTS: We included 11 RCTs with data for 7581 participants that compared nine different drugs.

BACKGROUND: This study examines the prevalence of dating and relationship violence (DRV) victimization, perpetration and joint victimization and perpetration, and associations between DRV and socio-demographic characteristics. METHODS: Cross-sectional self-report data from 74 908 students aged 11-16 from 193 schools across Wales were collected and analysed using generalized estimating equations to examine prevalence and predictors of emotional and physical DRV victimization, perpetration and joint victimization and perpetration. RESULTS: More girls reported emotional victimization (28%) and perpetration (18%) than boys (20% and 16%, respectively). More girls (8%) than boys (7%) reported physical perpetration. However, boys (17%) reported more physical victimization than girls (12%). Age-related trajectories of DRV victimization and perpetration were stronger in girls than in boys. Students from single or step parent homes, those in care, and certain ethnic minority groups had increased odds of DRV. No association was found between socioeconomic status and DRV. CONCLUSIONS: Age-related trajectories and the lack of social patterning by socioeconomic status point to the value of early, universal interventions, while some evidence of ethnic patterning and family structure-related risk factors suggest areas for further research and targeted interventions. DRV continues to be a major public health problem for which little UK-specific intervention evidence exists.

Qualitative comparative analysis (QCA) was originally developed as a tool for cross-national comparisons in macrosociology, but its use in evaluation and evidence synthesis of complex interventions is rapidly developing. QCA is theory-driven and relies on Boolean logic to identify pathways to an outcome (eg, is the intervention effective or not?). We use the example of two linked systematic reviews on weight management programs (WMPs) for adults-one focusing on user views (a "views synthesis") and one focusing on the effectiveness of WMPs incorporating dietary and physical activity-to demonstrate how a synthesis of user views can supply a working theory to structure a QCA. We discuss how a views synthesis is especially apt to supply this working theory because user views can (a) represent a "middle-range theory" of the intervention; (b) bring a participatory, democratic perspective; and (c) provide an idiographic understanding of how the intervention works that external taxonomies may not be able to furnish. We then discuss the practical role that the views synthesis played in our QCA examining pathways to effectiveness: (a) by suggesting specific intervention features and sharpening the focus on the most salient features to be examined, (b) by supporting interpretation of findings, and (c) by bounding data analysis to prevent data dredging.

Complex systems approaches to social intervention research are increasingly advocated. However, there have been few attempts to consider how models of intervention science, such as the UK's Medical Research Council complex interventions framework, might be reframed through a complex systems lens. This article identifies some key areas in which this framework might be reconceptualized, and a number of priority areas where further development is needed if alignment with a systems perspective is to be achieved. We argue that a complex systems perspective broadens the parameters of 'relevant' evidence and theory for intervention development, before discussing challenges in defining feasibility in dynamic terms. We argue that whole systems evaluations may be neither attainable, nor necessary; acknowledgment of complexity does not mean that evaluations must be complex, or investigate all facets of complexity. However, a systems lens may add value to evaluation design through guiding identification of key uncertainties, and informing decisions such as timings of follow-up assessments.

BACKGROUND: Rapid infant weight gain (RIWG) is a very strong predictor of childhood overweight and obesity (COO). Socioeconomic position (SEP) is also related to the risk of COO and parents of different SEP may differ in their reaction to accelerated infant weight gain. Together this could lead to differences in how weight gain and COO risk relate across SEP. This study aimed to analyse possible interaction of SEP and RIWG on COO risk. METHODS: a register-based longitudinal cohort study followed 19,894 healthy, term infants, born in Denmark between December 2011 and May 2015. Logistic regression models were used to estimate odds ratios (OR) of COO risk at 2 years (22-26 months) of age with 95% confidence intervals (95% CI) for categories of infancy weight gain based on changes in weight-for-age z-scores between 0 and 8-10 months of age (slow ( 0.67-1.34) and very rapid (> 1.34)). Possible multiplicative and additive interaction of SEP (based on household income and maternal education) on the relationship between infancy weight gain and COO were analysed. RESULTS: in total, 19.1 and 15.1% experienced rapid or very rapid weight gain, respectively, and 1497 (7.5%) children were classified with COO at follow-up. These prevalences were higher in those with lower levels of SEP. Adjusted OR for COO were 3.09 (95% CI [2.66-3.59]) and 7.58 (95% CI [6.51-8.83]) for rapid and very rapid weight gain, respectively, when household income was included in the model. Results were similar in the model including maternal education. No signs of interactions were detected on a multiplicative scale. Weak signs of additive interaction were present, but these values did not reach significance. CONCLUSION: Both rapid and very rapid weight gain were associated with substantially higher risks of COO but these associations were not modified by SEP. This indicates that promotion of healthy weight gain should take place in all population groups irrespective of their SEP.

. Background
. Schools struggle to timetable health education. Interventions integrating academic and health education to reduce substance use and violence offer promise. No current systematic reviews examine such interventions.
.
.
. Objectives
. To review evidence to explore the following questions: (1) what types of interventions integrating health and academic education in schools serving those aged 4–18 years have been evaluated? (2) What theories of change inform these interventions? (3) What factors facilitate or limit the successful implementation and receipt of such interventions, and what are the implications for the delivery of such implementations in the UK? (4) How effective are such interventions in reducing smoking and violence and the use of alcohol and drugs, and at increasing attainment? Does this vary by students’ sociodemographic characteristics? (5) What factors appear to influence the effectiveness of such interventions?
.
.
. Data sources
. In total, 19 databases were searched from 18 November to 22 December 2015, updating searches for outcome evaluations for violence on 28 February 2018 and for substance use on 14 May 2018. References were extracted from included studies and authors contacted.
.
.
. Review methods
. Included studies reported on theories of change, and process or outcome evaluations of interventions that integrated academic and health education to reduce substance use and/or violence. References were screened on the title/abstract and then on the full report. Data extraction and appraisal used Cochrane, Evidence for Policy and Practice Information Centre and other established tools. Theories of change and process data were qualitatively synthesised. Outcome evaluations were synthesised narratively and meta-analytically.
.
.
. Results
. In total, 78,451 unique references were originally identified and 62 reports included. Search updates on 28 February and 14 May 2018 retrieved a further 2355 and 1945 references, respectively, resulting in the inclusion of six additional reports. Thirty-nine reports described theories, 16 reports (15 studies) evaluated process and 41 reports (16 studies) evaluated outcomes. Multicomponent interventions are theorised to erode ‘boundaries’ (strengthen relationships) between academic and health education, teachers and students, behaviour in classrooms and in the wider school, and schools and families. Teachers, pro-social peers and parents are theorised to act as role models and reinforcers of healthy behaviours learnt in lessons. There was clear evidence that interventions are facilitated by supportive senior management and alignment with the schools’ ethos, collaborative and supportive teaching environments, and positive pre-existing student, teacher and parent attitudes towards interventions. The barriers were overburdened teachers who had little time to both learn and implement integrated curricula. The strongest evidence for effectiveness was found for the reduction of substance use in school key stages (KSs) 2 and 3. For example, a meta-analysis for substance use at KS3 reported a mean difference of –0.09 (95% confidence interval –0.17 to –0.01). A meta-analysis for effectiveness in reducing violence victimisation in KS2 found no effect. There was mixed evidence for effects on academic outcomes, with meta-analysis precluded by methodological heterogeneity.
.
.
. Limitations
. Study quality was variable. Integration was sometimes not emphasised in theories of change.
.
.
. Conclusions
. These interventions are undertheorised but involve multiple forms of boundary erosion. There is clear evidence of characteristics affecting implementation. Interventions are likely to have the greatest impact on substance use. These programmes may be effective in reducing substance use but do not appear to reduce violence and findings on educational impacts are mixed.
.
.
. Future work
. Future evaluations should assess interventions with clearer theories of change and examine academic outcomes alongside violence and substance use outcomes.

PURPOSE: the study of mental wellbeing requires reliable, valid, and practical measurement tools. One of the most widely used measures of mental wellbeing is the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS). Our aim was to examine the psychometric properties of SWEMWBS (a brief seven-item version) in a 'real-world' population sample of young people. METHODS: We used data from the 2017 School Health Research Network Student Health and Wellbeing Survey, completed by 103,971 students in years 7 to 11 from 193 secondary schools in Wales. We first estimated polychoric correlation matrices for the whole sample and by school year, and undertook a principal components analysis to check for configural invariance. Subsequently, we used a multiple-groups structural equation model with successively greater constraints to test measurement invariance. To examine external construct validity, we calculated correlations between the SWEMWBS score and four covariates: life satisfaction, somatisation, school pressure and bullying victimisation. RESULTS: Parallel analysis suggested that extraction of one factor was appropriate both overall and in each year group. Inspection of standardised loadings suggested that four items had progressively stronger correlations with the factor as students are older, but change in fit indices between models suggested that loadings and thresholds, but not residual variances, were invariant by age group. SWEMWBS scores were moderately correlated with measures of life satisfaction and somatisation, and weakly to moderately correlated with school pressure and bullying victimisation. CONCLUSIONS: This study adds to the growing evidence that SWEMWBS is appropriate for measuring mental wellbeing in young people and suggests that SWEMWBS is appropriate for tracking the development of wellbeing across adolescence.

OBJECTIVE: Parenting programs are the recommended strategy for the prevention and treatment of disruptive child behavior. Similar to most psychosocial interventions, it is unknown which components of parenting programs (ie, parenting techniques taught) actually contribute to program effects. Identifying what parents need to be taught to reduce disruptive child behavior can optimize intervention strategies, and refine theories on how parenting shapes disruptive child behavior. METHOD: in two meta-analyses, we updated the evidence-base for effectiveness of parenting programs delivered at various levels of prevention and treatment of disruptive behavior. We searched six databases (eg, PsycINFO, MEDLINE) for randomized trials and coded the parenting techniques taught in each program. We identified the techniques associated with program effects in general, and for prevention versus treatment, and immediate versus longer-term effects, specifically. RESULTS: Parenting program effects on disruptive behavior gradually increased per level of prevention (universal d = -0.21, selective d = -0.27, indicated d = -0.55) and treatment (d = -0.69) (Meta-Analysis 1: 154 trials, 398 effect sizes). Three of 26 parenting techniques were associated with stronger program effects: positive reinforcement, praise in particular, and natural/logical consequences. Several additional techniques (eg, relationship building and parental self-management) were associated with stronger effects in treatment but weaker effects in prevention. No techniques were associated with stronger longer-term effects (Meta-Analysis 2: 42 trials, 157 effect sizes). CONCLUSION: Positive reinforcement and nonviolent discipline techniques (eg, applying natural/logical consequences) seem to be key parenting program techniques to reduce disruptive child behavior. Additional techniques (eg, parental self-management skills) might improve program effects in treatment, but not in prevention.

Background: Dating and relationship violence (DRV)-intimate partner violence during adolescence-encompasses physical, sexual and emotional abuse. DRV is associated with a range of adverse health outcomes including injuries, sexually transmitted infections, adolescent pregnancy and mental health issues. Experiencing DRV also predicts both victimisation and perpetration of partner violence in adulthood.Prevention targeting early adolescence is important because this is when dating behaviours begin, behavioural norms become established and DRV starts to manifest. Despite high rates of DRV victimisation in England, from 22 to 48% among girls and 12 to 27% among boys ages 14-17 who report intimate relationships, no RCTs of DRV prevention programmes have taken place in the UK. Informed by two school-based interventions that have shown promising results in RCTs in the USA-Safe Dates and Shifting Boundaries-Project Respect aims to optimise and pilot a DRV prevention programme for secondary schools in England. Methods: Design: optimisation and pilot cluster RCT. Trial will include a process evaluation and assess the feasibility of conducting a phase III RCT with embedded economic evaluation. Cognitive interviewing will inform survey development.Participants: optimisation involves four schools and pilot RCT involves six (four intervention, two control). All are secondary schools in England. Baseline surveys conducted with students in years 8 and 9 (ages 12-14). Follow-up surveys conducted with the same cohort, 16 months post-baseline. Optimisation sessions to inform intervention and research methods will involve consultations with stakeholders, including young people.Intervention: school staff training, including guidance on reviewing school policies and addressing 'hotspots' for DRV and gender-based harassment; information for parents; informing students of a help-seeking app; and a classroom curriculum for students in years 9 and 10, including a student-led campaign.Primary outcome: the primary outcome of the pilot RCT will be whether progression to a phase III RCT is justified. Testing within the pilot will also determine which of two existing scales is optimal for assessing DRV victimisation and perpetration in a phase III RCT. Discussion: This will be the first RCT of an intervention to prevent DRV in the UK. If findings indicate feasibility and acceptability, we will undertake planning for a phase III RCT of effectiveness. Trial registration: ISRCTN, ISRCTN 65324176. Registered 8 June 2017.

The socioeconomic inequalities found in child and adolescent mental wellbeing are increasingly acknowledged. Although interventions increasingly focus on school holidays as a critical period for intervention to reduce inequalities, no studies have modelled the role of summer holiday experiences in explaining socioeconomic inequalities in wellbeing. For this study, we analysed survey data of 103,971 adolescents from 193 secondary schools in Wales, United Kingdom, which included measures of family affluence, experiences during the summer holidays (hunger, loneliness, time with friends and physical activity) and mental wellbeing and internalising symptoms on return to school. Structural equation modelling was used to analyse the data. Although family affluence retained a direct inverse association with student mental wellbeing (r = -0.04, p < 0.001), 65.2% of its association with mental wellbeing was mediated by the experiences over the summer holidays. FAS score was not directly associated with the student's self-reports of internalising symptoms (r = 0.00, p > 0.05). of all summer holiday experiences, the strongest mediational pathway was observed for reports of loneliness. Although more structural solutions to poverty remain essential, school holiday interventions may have significant potential for reducing socioeconomic inequalities in mental health and wellbeing on young people's return to school through reducing loneliness, providing nutritious food and opportunities for social interaction.

Strong arguments have been made for early intervention for child problems, stating that early is more effective than later, as the brain is more malleable, and costs are lower. However, there is scant evidence from trials to support this hypothesis, which we therefore tested in two well-powered, state-of-the-art meta-analyses with complementary strengths: (a) Individual participant data (IPD) meta-analysis of European trials of Incredible Years parenting intervention (k = 13, n = 1696; age = 2-11); (b) Larger, trial-level robust variance estimation meta-analysis of a wider range of parenting programs (k = 156, n = 13,378, Mage  = 2-10) for reducing disruptive behavior. Both analyses found no evidence that intervention earlier in childhood was more effective; programs targeted at a narrower age range were no more effective than general ones.

OBJECTIVE: Analyze the measurement invariance and the factor structure of the Patient Health Questionnaire-9 (PHQ-9) in the Peruvian population. METHOD: Secondary data analysis performed using cross-sectional data from the Health Questionnaire of the Demographic and Health Survey in Peru. Variables of interest were the PHQ-9 and demographic characteristics (sex, age group, level of education, socioeconomic status, marital status, and area of residence). Factor structure was evaluated by standard confirmatory factor analysis (CFA), and measurement invariance by multi-group CFA, using standard goodness-of-fit indices criteria for interpreting results from both CFAs. Analysis of the internal consistency (α and ω) was also pursued. RESULTS: Data from 30,449 study participants were analyzed, 56.7% were women, average age was 40.5 years (standard deviation (SD) = 16.3), 65.9% lived in urban areas, 74.6% were married, and had 9 years of education on average (SD = 4.6). From standard CFA, a one-dimensional model presented the best fit (CFI = 0.936; RMSEA = 0.089; SRMR = 0.039). From multi-group CFA, all progressively restricted models had ΔCFI

BACKGROUND: Current UK guidance recommends that adolescents with obesity attend a family-based multi-component obesity intervention. However, these programmes suffer from low recruitment and high rates of attrition. Understanding the views of adolescents is necessary for developing future interventions. The aim of this systematic review was to synthesize and explore the views of adolescents who have attended an obesity intervention. METHODS: Published literature was identified by searching six databases. Studies of adolescents (12-17 years) who attended an obesity intervention were examined. Only studies that collected and analysed data qualitatively were included. Full texts were analysed using thematic synthesis. RESULTS: Twenty-eight studies were included. Thirty-five analytical themes were developed that were broadly divided into seven domains. Key themes included ensuring adolescents receive a 'tailored intervention' that involves 'active engagement'. Support from professionals, family and peers were valued highly. Adolescents expressed 'prior fears of attending interventions' and wanted 'longer term support'. 'Enjoyment of sport and physical activity' was evident, and adolescents were strongly motivated by improving body image and social desirability. DISCUSSION: Considering the views of adolescents attending obesity interventions may help to inform policy makers in the development of future interventions. This may lead to an improvement in recruitment and attrition rates.

© 2019 John Wiley. &. Sons, Ltd. Parenting interventions are widely used to reduce physical child abuse, but evidence for their effectiveness is mixed, partly because standard methods for synthesising the effectiveness of interventions do not address complex causation. We addressed this by using qualitative comparative analysis to understand pathways to effectiveness in social learning theory-based parenting interventions. After a systematic search of nine databases and independent and duplicate study selection, we included 14 interventions from ten evaluations. We categorised nine as most effective and five as least effective. We labelled interventions as to the presence or absence of parental self-management, attachment-based, alternative punishment or proactive parenting components. We examined how these combined in the most effective and least effective interventions, and identified common pathways to most effectiveness and least effectiveness. The final pathways revealed the importance of two components: alternative punishment strategies and parental self-management strategies. It was not clear that adding more components to an intervention necessarily translated to more effectiveness; indeed, this could backfire, as many of the least effective interventions combined multiple strategies without teaching parental self-management. Our findings may be useful to intervention developers and implementers when considering new interventions. Future research should seek to test combinations of components for differential effectiveness between the most effective pathways. ‘[A] qualitative comparative analysis to understand pathways to effectiveness in social learning theory-based parenting interventions’. Key Practitioner Messages: the effectiveness of social learning theory-based parenting interventions for physical child abuse is variable. We identified two key, but not necessary, components: alternative punishment strategies and parental self-management strategies. Adding more components did not necessarily lead to high effectiveness, and in some cases this could backfire when parental self-management was not included.

BACKGROUND: Attention to women's and girls' menstrual needs is critical for global health and gender equality. The importance of this neglected experience has been elucidated by a growing body of qualitative research, which we systematically reviewed and synthesised. METHODS AND FINDINGS: We undertook systematic searching to identify qualitative studies of women's and girls' experiences of menstruation in low- and middle-income countries (LMICs). of 6,892 citations screened, 76 studies reported in 87 citations were included. Studies captured the experiences of over 6,000 participants from 35 countries. This included 45 studies from sub-Saharan Africa (with the greatest number of studies from Kenya [n = 7], Uganda [n = 6], and Ethiopia [n = 5]), 21 from South Asia (including India [n = 12] and Nepal [n = 5]), 8 from East Asia and the Pacific, 5 from Latin America and the Caribbean, 5 from the Middle East and North Africa, and 1 study from Europe and Central Asia. Through synthesis, we identified overarching themes and their relationships to develop a directional model of menstrual experience. This model maps distal and proximal antecedents of menstrual experience through to the impacts of this experience on health and well-being. The sociocultural context, including menstrual stigma and gender norms, influenced experiences by limiting knowledge about menstruation, limiting social support, and shaping internalised and externally enforced behavioural expectations. Resource limitations underlay inadequate physical infrastructure to support menstruation, as well as an economic environment restricting access to affordable menstrual materials. Menstrual experience included multiple themes: menstrual practices, perceptions of practices and environments, confidence, shame and distress, and containment of bleeding and odour. These components of experience were interlinked and contributed to negative impacts on women's and girls' lives. Impacts included harms to physical and psychological health as well as education and social engagement. Our review is limited by the available studies. Study quality was varied, with 18 studies rated as high, 35 medium, and 23 low trustworthiness. Sampling and analysis tended to be untrustworthy in lower-quality studies. Studies focused on the experiences of adolescent girls were most strongly represented, and we achieved early saturation for this group. Reflecting the focus of menstrual health research globally, there was an absence of studies focused on adult women and those from certain geographical areas. CONCLUSIONS: Through synthesis of extant qualitative studies of menstrual experience, we highlight consistent challenges and developed an integrated model of menstrual experience. This model hypothesises directional pathways that could be tested by future studies and may serve as a framework for program and policy development by highlighting critical antecedents and pathways through which interventions could improve women's and girls' health and well-being.

BACKGROUND: Schools can play an important role in promoting health. However, many education policies and institutions are increasingly emphasising academic attainment targets, which appear to be diminishing the time available for health education lessons. Interventions that integrate both health and academic learning may present an ideal solution, simultaneously addressing health education and academic development. The theories of change underlying these interventions are therefore of interest, but are poorly studied. METHODS: a systematic review of evaluations of interventions that integrate academic and health education for reduced substance use and/or violence was carried out. As part of this, reports describing theory were assessed for quality and data extracted. Theoretical data were synthesised within and across individual interventions using reciprocal translation and meta-ethnographic line of argument synthesis to produce an overall theory of change for interventions that integrate health and academic education to prevent substance use and violence. RESULTS: Forty-eight reports provided theoretical descriptions of 18 interventions. An overarching theory that emerged was that eroding 'boundaries' at multiple and mutually reinforcing levels-by integrating academic and health education, by transforming relationships between teachers and students, by generalising learning from classrooms to the wider school environment and by ensuring consistent messages from schools and families-is intended to lead to the development of a community of engaged students oriented towards pro-social behaviour and away from substance use, violence and other risk behaviours. CONCLUSIONS: Eroding 'boundaries' between health and academic education, teachers and students, classrooms and the wider school and schools and families were seen to be the most critical to establishing new frameworks of family, classroom or school organisation that are conducive to promoting both academic and social-emotional outcomes. Whether such interventions are feasible to implement and effective in reducing risk behaviours will be examined in other reports arising from the review.

Parenting programs for reducing disruptive child behavior are built on two main perspectives: relationship enhancement (i.e. unconditional sensitivity diminishes disruptiveness) and behavior management (i.e. conditional rewards diminish disruptiveness). Two meta-analyses (156 and 41 RCTs; Ntotal  = 15,768; Mchildage  = 1-11 years) tested the theoretical model that integrating relationship enhancement with behavior management is superior to behavior management alone. The integrative approach showed no overall superiority. Relative to behavior management, the integrative approach was superior in treatment settings, but inferior in prevention settings (Meta-analysis 1). The integrative approach and behavior management approach did not have differential sustained effects up to 3 years after the program (Meta-analysis 2). Findings argue against current practice to implement the same parenting programs in treatment and prevention settings.

© 2018 the Cochrane Collaboration. This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: This review seeks to identify and synthesise studies that evaluate the effectiveness of prevention interventions for MSM that combine at least two of the three categories of intervention modality (biomedical, behavioural and structural) compared either to other HIV prevention interventions or to minimal/no HIV prevention. Below, descriptions of the criteria that will be used to categorise intervention components are provided under the heading 'Types of interventions' and the full list of outcomes of interest are provided in the section 'Types of outcome measures'. All planned comparisons are detailed in the section 'Data synthesis', followed by the planned variables of interest for subgroup and meta-regression analyses.

BACKGROUND: We systematically reviewed the comparative effectiveness of injectable beta-interferons (IFN-β) and glatiramer acetate (GA) on annualised relapse rate (ARR), progression and discontinuation due to adverse events (AEs) in RRMS, using evidence from within the drugs' recommended dosages. METHODS: We updated prior comprehensive reviews, checked references of included studies, contacted experts in the field, and screened websites for relevant publications to locate randomised trials of IFN-β and GA with recommended dosages in RRMS populations, compared against placebo or other recommended dosages. Abstracts were screened and assessed for inclusion in duplicate and independently. Studies were appraised using the Cochrane risk of bias tool. Rate ratios for ARR, hazard ratios for time to progression, and risk ratios for discontinuation due to AEs were synthesised in separate models using random effects network meta-analysis. RESULTS: We identified 24 studies reported in 42 publications. Most studies were at high risk of bias in at least one domain. All drugs had a beneficial effect on ARR as compared to placebo, but not compared to each other, and findings were robust to sensitivity analysis. We considered time to progression confirmed at 3 months and confirmed at 6 months in separate models; while both models suggested that the included drugs were effective, findings were not consistent between models. Discontinuation due to AEs did not appear to be different between drugs. CONCLUSIONS: Meta-analyses confirmed that IFN-β and GA reduce ARR and generally delay progression as defined in these trials, though there was no clear 'winner' across outcomes. Findings are additionally tempered by the high risk of bias across studies, and the use of an impairment/mobility scale to measure disease progression. Future research should consider more relevant measures of disability and, given that most trials have been short-term, consider a longitudinal approach to comparative effectiveness.

PURPOSE: This systematic review with network meta-analysis compared the efficacy and safety of currently licensed second-line treatments in patients with late stage non-small cell lung cancer (NSCLC). METHODS: Randomised controlled trials (RCTs) of participants with advanced/metastatic NSCLC receiving second/third line treatments were screened. We searched electronic databases (MEDLINE; EMBASE; Web of Science) from January, 2000 to July, 2017. Two reviewers screened bibliographic records, extracted data, and assessed risk of bias of included studies. The outcomes were overall survival (OS), progression-free survival (PFS), and drug-related grade 3-5 adverse-events (AEs). We pooled study-specific hazard ratios (HR; for OS and PFS) and risk ratios (RR; for AEs) using conventional and network-meta-analyses, and ranked interventions by the surface under the cumulative ranking curve. FINDINGS: We included 11 RCTs (7,581 participants) comparing nine drugs. All drugs except for erlotinib significantly improved OS compared to docetaxel. Nivolumab was the highest ranking drug followed by atezolizumab and pembrolizumab. There was no significant difference in OS across these three drugs (HR = 0.98, 95% CI 0.79, 1.21 for nivolumab vs atezolizumab; HR = 0.98, 95% CI 0.77, 1.25 for nivolumab vs pembrolizumab). For PFS, ramucirumab + docetaxel and nivolumab were the drugs with the highest ranking. All interventions except ramucirumab + docetaxel had a reduced risk for severe drug-related AEs vs. docetaxel. of the drugs with the highest ranking on AEs, nivolumab was significantly safer compared to atezolizumab (RR = 0.55, 95% CI 0.38, 0.79) or pembrolizumab (RR = 0.52, 95% CI 0.34, 0.81). IMPLICATIONS: Nivolumab, pembrolizumab and atezolizumab exhibited superior benefit/risk balance compared to other licensed drugs used late stage NSCLC. Our results indicate that the use of immunotherapies in people diagnosed with non-specific late stage NSCLC should be promoted. The use of docetaxel may now be judged irrelevant as a comparator intervention for approval of new drugs for second line treatment of NSCLC. STUDY REGISTRATION NUMBER: PROSPERO CRD42017065928.

BACKGROUND: Evidence to understand which gay and bisexual men (GBM) inject drugs remains scant, especially in the UK. We describe correlates of last-year injecting in UK GBM, and characterise subgroups of GBM who inject drugs by types of drugs used. METHODS: Using data from the 2014 Gay Men's Sex Survey, an opportunistic internet-based survey conducted of GBM living in the UK, we examined via logistic regression correlates with any injecting of six drugs (amphetamine/speed, crystal methamphetamine, heroin, mephedrone, GHB/GBL, and ketamine) in the last year. We estimated latent class models to understand underlying subgroups of injecting drug use among GBM reporting injecting drug use in the last year. RESULTS: Injecting was most common in GBM who were of middle age, who were HIV seropositive, and who lived in London, and was significantly associated with sexual risk with multiple partners in the last year, whether steady or non-steady. Most GBM who engaged in injecting either injected crystal methamphetamine, mephedrone or both (class 1, chemsex, 88.6% of injectors), whereas a smaller group had a focus on opiates (class 2, opiate, 7.9%). A small but identifiable subgroup (class 3, eclectic, 3.5%) engaged in injecting across the range of drugs examined. CONCLUSIONS: This is the first epidemiological analysis to describe subgroups of injecting, and to describe correlates of injecting drug use, in UK GBM. Implications for design of harm reduction services include a need to focus on injecting drug use beyond opiates, currently the focus of most harm reduction services.

The reform of provider payment systems, from retrospective to prospective payment, has been heralded as the right move to contain costs in the light of rising health expenditures in many countries. However, there are concerns on quality trade-off. The heightened attention given to prospective payment system (PPS) reforms and the rise of empirical evidence regarding PPS interventions among developing countries suggest that a systematic review is necessary to understand the effects of PPS reforms in developing countries. A systematic search of 14 databases and a hand search of health policy journals and grey literature from October to November 2016 were carried out, guided by a set of inclusion and exclusion criteria. Data were extracted based on the Consolidated Health Economics Evaluation Reporting Standards checklist. Drummond's 10-item checklist for economic evaluation, Cochrane Collaboration's tool in assessing risk of bias for randomized trials, and Risk of Bias in Non-randomized Studies of Interventions were used to critically appraise the evidence. A total of 12 studies reported in China, Thailand and Vietnam were included in this review. Substantial heterogeneity was present in PPS policy design across different localities. PPS interventions were found to have reduced health expenditures on both the supply and demand side, as well as length of stay and readmission rates. In addition, PPS generally improved service quality outcomes by reducing the likelihood or percentage of physicians prescribing unnecessary drugs and diagnostic procedures. PPS is a promising policy tool for middle-income countries to achieve reasonable health policy objectives in terms of cost containment without necessarily compromising the quality of care. More evaluations of PPS will need to be conducted in the future in order to broaden the evidence base beyond middle-income countries.

BACKGROUND: Prevention of substance (alcohol, tobacco, illegal/legal drug) use in adolescents is a public health priority. As the scope for school-based health education is constrained in school timetables, interventions integrating academic and health education have gained traction in the UK and elsewhere, though evidence for their effectiveness remains unclear. We sought to synthesize the effectiveness of interventions integrating academic and health education for the prevention of substance use. METHODS: We searched 19 databases between November and December 2015, among other methods. We included randomized trials of interventions integrating academic and health education targeting school students aged 4-18 and reporting substance use outcomes. We excluded interventions for specific health-related subpopulations (e.g. children with behavioural difficulties). Data were extracted independently in duplicate. Outcomes were synthesized by school key stage (KS) using multilevel meta-analyses, for substance use, overall and by type. RESULTS: We identified 7 trials reporting substance use. Interventions reduced substance use generally in years 7-9 (KS3) based on 5 evaluations (d = -0.09, 95% CI [-0.17, -0.01], I2  = 35%), as well as in years 10-11 (KS4) based on 3 evaluations (-0.06, [-0.09, -0.02]; I2  = 0%). Interventions were broadly effective for reducing specific alcohol, tobacco, and drug use in both KS groups. CONCLUSIONS: Evidence quality was highly variable. Findings for years 3-6 and 12-13 could not be meta-analysed, and we could not assess publication bias. Interventions appear to have a small but significant effect reducing substance use. Specific methods of integrating academic and health education remain poorly understood.

OBJECTIVE: Positive youth development (PYD) often aims to prevent tobacco, alcohol, and drugs use and violence. We systematically reviewed PYD interventions, synthesizing process, and outcomes evidence. Synthesis of outcomes, published elsewhere, found no overall evidence of reducing substance use or violence but notable variability of fidelity. Our synthesis of process evaluations examined how implementation varied and was influenced by context. DATA SOURCE: Process evaluations of PYD aiming to reduce substance use and violence. Study Inclusion Criteria: Overall review published since 1985; written in English; focused on youth aged 11 to 18 years; focused on interventions addressing multiple positive assets; reported on theory, process, or outcomes; and concerned with reducing substance use or violence. Synthesis of process evaluations examined how implementation varies with or is influenced by context. DATA EXTRACTION: Two reviewers in parallel. DATA SYNTHESIS: Thematic synthesis. RESULTS: We identified 12 reports. Community engagement enhanced program appeal. Collaboration with other agencies could broaden the activities offered. Calm but authoritative staff increased acceptability. Staff continuity underpinned diverse activities and durable relationships. Empowering participants were sometimes in tension with requiring them to engage in diverse activities. CONCLUSION: Our systematic review identified factors that might help improve the fidelity and acceptability of PYD interventions. Addressing these might enable PYD to fulfill its potential as a means of promoting health.

OBJECTIVES: to systematically review evidence on the effectiveness of interventions including integration of academic and health education for reducing physical aggression and violence, and describe the content of these interventions. DATA SOURCES: Between November and December 2015, we searched 19 databases and 32 websites and consulted key experts in the field. We updated our search in February 2018. ELIGIBILITY CRITERIA: We included randomised trials of school-based interventions integrating academic and health education in students aged 4-18 and not targeted at health-related subpopulations (eg, learning or developmental difficulties). We included evaluations reporting a measure of interpersonal violence or aggression. DATA EXTRACTION AND ANALYSIS: Data were extracted independently in duplicate, interventions were analysed to understand similarities and differences and outcomes were narratively synthesised by key stage (KS). RESULTS: We included 13 evaluations of 10 interventions reported in 20 papers. Interventions included either full or partial integration, incorporated a variety of domains beyond the classroom, and used literature, local development or linking of study skills and health promoting skills. Evidence was concentrated in KS2, with few evaluations in KS3 or KS4, and evaluations had few consistent effects; evaluations in KS3 and KS4 did not suggest effectiveness. DISCUSSION: Integration of academic and health education may be a promising approach, but more evidence is needed. Future research should consider the 'lifecourse' aspects of these interventions; that is, do they have a longitudinal effect? Evaluations did not shed light on the value of different approaches to integration.

BACKGROUND: Within increasingly constrained school timetables, interventions that integrate academic and health education to reduce substance use and violence may hold promise as a category of intervention that can positively affect both academic and health outcomes. There are no current systematic reviews exploring the effectiveness of such interventions or factors that affect their implementation. METHODS: a total of 19 bibliographic databases and 32 websites were searched. References were also extracted from the reference lists of included studies, and experts and authors were contacted to identify relevant studies. We included reports with no restrictions on language or date. References were screened on title/abstract and those not thus excluded were screened on full report. Data extraction and appraisal followed the Critical Appraisal Skills Programme, Evidence for Policy and Practice Information and Co-ordinating Centre and Cochrane tools. Extracted process data were qualitatively meta-synthesised for common themes. RESULTS: Seventy-eight thousand four hundred fifty-one unique references were identified, and 62 reports were included. A total of 16 reports (reporting on 15 studies of 12 interventions) evaluated process. Key facilitators of integrated academic and health curricula were supportive senior management and alignment of the intervention with school ethos; a positive teaching environment, including positive perceptions around the ability to be flexible in the adaptation and delivery of integrated academic and health curricula; positive pre-existing student and teacher attitudes towards intervention content; and parental support of interventions, largely through reinforcement of messaging at home. Important barriers were over-burdened teachers, with little time to learn and implement integrated curricula. CONCLUSION: Several useful facilitating and inhibiting factors linked to the implementation of interventions that integrate academic and health education for reduced substance use and/or violence were identified, providing tentative but insightful evidence of context-specific issues that may impact intervention success. However, overall, there is still a considerable gap in our understanding of how to achieve the successful implementation of these interventions.

Ixazomib is an oral proteasome inhibitor used in combination with lenalidomide plus dexamethasone (IXA-LEN-DEX) and licensed for relapsed or refractory multiple myeloma. As part of a single technology appraisal (ID807) undertaken by the National Institute of Health and Care Excellence, the Evidence Review Group, Warwick Evidence was invited to independently review the evidence submitted by the manufacturer of ixazomib, Takeda UK Ltd. The main source of clinical effectiveness data about IXA-LEN-DEX came from the Tourmaline-MM1 randomized controlled trial in which 771 patients with relapsed or refractory multiple myeloma received either IXA-LEN-DEX or placebo-LEN-DEX as their second-, third-, or fourth-line treatment. Takeda estimated the cost effectiveness of IXA-LEN-DEX using a de-novo partitioned-survival model with three health states (pre-progression, post-progression, and dead). In their first submission, this model was used to estimate the cost effectiveness of IXA-LEN-DEX vs. bortezomib plus dexamethasone (BORT-DEX) in second-line treatment, and of IXA-LEN-DEX vs. LEN-DEX in third-line treatment. To estimate the relative clinical performance of IXA-LEN-DEX vs. BORT-DEX, Takeda conducted network meta-analyses for important outcomes. The network meta-analysis for overall survival was found to be flawed in several respects, but mainly because a hazard ratio input for one of the studies in the network had been inverted, resulting in a large inflation of the claimed superiority of IXA-LEN-DEX over BORT-DEX and a considerable overestimation of its cost effectiveness. In subsequent submissions, Takeda withdrew second-line treatment as an option for IXA-LEN-DEX. The manufacturer's first submission comparing IXA-LEN-DEX with LEN-DEX for third-line therapy employed Tourmaline-MM1 data from third- and fourth-line patients as proxy for a third-line population. The appraisal committee did not consider this reasonable because randomization in Tourmaline-MM1 was stratified according to one previous treatment and two or more previous treatments. A further deficiency was considered to be the manufacturer's use of interim survival data rather than the most mature data available. A second submission from the company focussed on IXA-LEN-DEX vs. LEN-DEX as third- or fourth-line treatment (the two or more previous lines population) and a new patient access scheme was introduced. Covariate modeling of survival outcomes was proposed using the most mature survival data. The Evidence Review Group's main criticisms of the new evidence included: the utility associated with the pre-progression health state was overestimated, treatment costs of ixazomib were underestimated, survival models were still associated with great uncertainty, leading to clinically implausible anomalies and highly variable incremental cost-effectiveness ratio estimates, and the company had not explored a strong assumption that the survival benefit of IXA-LEN-DEX over LEN-DEX would be fully maintained for a further 22 years beyond the observed data, which encompassed only approximately 2.5 years of observation. The appraisal committee remained unconvinced that ixazomib represented a cost-effective use of National Health Service resources. Takeda's third submission offered new base-case parametric models for survival outcomes, a new analysis of utilities, and proposed a commercial access agreement. In a brief critique of the third submission, the Evidence Review Group agreed that the selection of appropriate survival models was problematic and at the request of the National Institute for Health Care and Excellence investigated external sources of evidence regarding survival outcomes. The Evidence Review Group considered that some cost and utility estimates in the submission may have remained biased in favor of ixazomib. As a result of their third appraisal meeting, the committee judged that for the two to three prior therapies population, and at the price agreed in a commercial access agreement, ixazomib had the potential to be cost effective. It was referred to the Cancer Drugs Fund so that further data could accrue with the aim of diminishing the clinical uncertainties.

BACKGROUND: Comparisons between narrative synthesis and meta-analysis as synthesis methods in systematic reviews are uncommon within the same systematic review. We re-analysed a systematic review on the effects of plain packaging of tobacco on attractiveness. We sought to compare different synthesis approaches within the same systematic review and shed light on the comparative benefits of each approach. METHODS: in our re-analysis, we included results relating to attractiveness in included reports. We extracted findings from studies and converted all estimates of differences in attractiveness to Cohen's d. We used multilevel meta-analysis to account for clustering of effect sizes within studies. RESULTS: of the 19 studies reporting results on attractiveness, seven studies that included between-subjects analyses could be included in the meta-analysis. Plain packs were less attractive than branded packs (d = - 0.59, 95% CI [- 0.71, - 0.47]), with negligible but uncertain between-studies heterogeneity (I2 = 0%, 95% CI [0.00, 70.81]) and high within-study heterogeneity (I2 = 92.6%, 95% CI [91.04, 93.90]). CONCLUSIONS: the meta-analysis found, similar to the narrative synthesis, that respondents typically rated plain packaging as less attractive than alternative (e.g. branded) tobacco packs. However, there were several trade-offs between analysis methods in the types and bodies of evidence each one contained and in the difference between partial precision and breadth of conclusions. Analysis methods were different in respect of the role of judgement and contextual variation and in terms of estimation and unexpected effect modification. In addition, we noted that analysis methods were different in how they accounted for heterogeneity and consistency.

This study aimed to identify critical features of successful lifestyle weight management interventions for overweight children (0-11years). Eleven qualitative UK-based studies examining children's, parents' and providers' perspectives and experiences of programmes were synthesised to identify components felt to be critical. Studies for this views synthesis were identified from existing reviews and an update of one review's search, which was run in December 2015. The identified components were then explored in a synthesis of intervention evaluations (five 'most effective' and 15 'least effective') conducted in western Europe, North America, Australia or New Zealand. The intervention evaluations were identified from existing reviews and an update of one review's search, which was run in March 2016. This evaluation synthesis was carried out using Qualitative Comparative Analysis. Three important mechanisms were present in all the most effective interventions but absent in all the least effective: 1/ showing families how to change: a) providing child physical activity sessions, b) delivering practical behaviour change strategy sessions, c) providing calorie intake advice; 2/ ensuring all the family are on board: a) delivering discussion/education sessions for both children and parents, b) delivering child-friendly sessions, c) aiming to change behaviours across the whole family; 3/ enabling social support for both parents and children by delivering both child group sessions and parent group sessions. To conclude, programmes should ensure the whole family is on board the programme, that parents and children can receive social support and are not just told what to change, but shown how.

Composite indices have been prominently used in poverty research. However, validity of these indices remains subject to debate. This paper examines the validity of a common type of composite poverty indices using data from a cross-sectional survey of 2477 households in urban and rural KwaZulu-Natal, South Africa. Multiple-group comparisons in structural equation modelling were employed for testing differences in the measurement model across urban and rural groups. The analysis revealed substantial variations between urban and rural respondents both in the conceptualisation of poverty as well as in the weights and importance assigned to individual poverty indicators. The validity of a 'one size fits all' measurement model can therefore not be confirmed. In consequence, it becomes virtually impossible to determine a household's poverty level relative to the full sample. Findings from our analysis have important practical implications in nuancing how we can sensitively use composite poverty indices to identify poor people.

BACKGROUND: What are the parenting behaviors that shape child compliance? Most research on parent-child interactions relies on correlational research or evaluations of "package deal" interventions that manipulate many aspects of parenting at the same time. Neither approach allows for identifying the specific parenting behaviors that shape child compliance. To overcome this, we systematically reviewed and meta-analyzed available evidence on the effects of experimentally manipulated, discrete parenting behaviors-a niche in parent-child interaction research that contributes unique information on the specific parenting behaviors that shape child behavior. METHODS: We identified studies by systematically searching databases and through contacting experts. Nineteen studies (75 effect sizes) on four discrete parenting behaviors were included: praise, verbal reprimands, time-out, and ignore. In multilevel models, we tested for each parenting behavior whether it increased child compliance, including both observed and parent-reported measures of child compliance. RESULTS: Providing "time-out" for noncompliance robustly increased both observed and parent-reported child compliance (ds = 0.84-1.72; 95% CI 0.30 to 2.54). The same holds for briefly ignoring the child after non-compliance (ds = 0.36-1.77; 95% CI 0.04 to 2.90). When observed and parent-reported outcomes were combined, but not when they were examined separately, verbal reprimands also increased child compliance (d = 0.72; 95% CI 0.26 to 1.19). Praise did not increase child compliance (ds = -0.27-1.19; 95% CI -2.04 to 1.59). CONCLUSION: Our findings suggest that of the discrete parenting behaviors that are experimentally studied in multiple trials, especially time-out and ignore, and to some extent verbal reprimands, shape child compliance.

BACKGROUND: the estimated lifetime prevalence of physical or sexual intimate partner violence (IPV) is 30% among women worldwide. Understanding risk and protective factors is essential for designing effective prevention strategies. OBJECTIVES: to quantify the associations between prospective-longitudinal risk and protective factors and IPV and identify evidence gaps. SEARCH METHODS: We conducted systematic searches in 16 databases including MEDLINE and PsycINFO from inception to June 2016. The study protocol is registered with PROSPERO (CRD42016039213). SELECTION CRITERIA: We included published and unpublished studies available in English that prospectively analyzed any risk or protective factor(s) for self-reported IPV victimization among women and controlled for at least 1 other variable. DATA COLLECTION AND ANALYSIS: Three reviewers were involved in study screening. One reviewer extracted estimates of association and study characteristics from each study and 2 reviewers independently checked a random subset of extractions. We assessed study quality with the Cambridge Quality Checklists. When studies investigated the same risk or protective factor using similar measures, we computed pooled odds ratios (ORs) by using random-effects meta-analyses. We summarized heterogeneity with I2 and τ2. We synthesized all estimates of association, including those not meta-analyzed, by using harvest plots to illustrate evidence gaps and trends toward negative or positive associations. MAIN RESULTS: of 18 608 studies identified, 60 were included and 35 meta-analyzed. Most studies were based in the United States. The strongest evidence for modifiable risk factors for IPV against women were unplanned pregnancy (OR = 1.66; 95% confidence interval [CI] = 1.20, 1.31) and having parents with less than a high-school education (OR = 1.55; 95% CI = 1.10, 2.17). Being older (OR = 0.96; 95% CI = 0.93, 0.98) or married (OR = 0.93; 95% CI = 0.87, 0.99) were protective. CONCLUSIONS: to our knowledge, this is the first systematic, meta-analytic review of all risk and protective factors for IPV against women without location, time, or publication restrictions. Unplanned pregnancy and having parents with less than a high-school education, which may indicate lower socioeconomic status, were shown to be risk factors, and being older or married were protective. However, no prospective-longitudinal study investigated the associations between IPV against women and any community or structural factor outside the United States, and more studies investigated risk factors related to women as opposed to their partners. Public health implications. This review highlights that prospective evidence for perpetrator- and context-related risk and protective factors for women's experiences of IPV outside of the United States is lacking and urgently needed to inform global policy recommendations. The current evidence base of prospective studies suggests that, at least in the United States, education and sexual health interventions may be effective targets for preventing IPV against women, with young, unmarried women at greatest risk.

BACKGROUND: Beta-interferon (IFN-β) and glatiramer acetate (GA) have been evaluated in people with clinically isolated syndrome (CIS) with the aim to delay a second clinical attack and a diagnosis of clinically definite multiple sclerosis (CDMS). We systematically reviewed trials evaluating the short- and long-term clinical effectiveness of these drugs in CIS. METHODS: We searched multiple electronic databases. We selected randomised controlled studies (RCTs) conducted in CIS patients and where the interventions were IFN-β and GA. Main outcomes were time to CDMS, and discontinuation due to adverse events (AE). We compared interventions using random-effect network meta-analyses (NMA). We also reported outcomes from long-term open-label extension (OLE) studies. RESULTS: We identified five primary studies. Four had open-label extensions following double-blind periods comparing outcomes between early vs delayed DMT. Short-term clinical results (double-blind period) showed that all drugs delayed CDMS compared to placebo. Indirect comparisons did not suggest superiority of any one active drug over another. We could not undertake a NMA for discontinuation due to AE. Long-term clinical results (OLE studies) showed that the risk of developing CDMS was consistently reduced across studies after early DMT treatment compared to delayed DMT (HR = 0.64, 95% CI 0.55, 0.74). No data supported the benefit of DMTs in reducing the time to, and magnitude of, disability progression. CONCLUSIONS: Meta-analyses confirmed that IFN-β and GA delay time to CDMS compared to placebo. In the absence of evidence that early DMTs can reduce disability progression, future research is needed to better identify patients most likely to benefit from long-term DMTs.

Background: Since the introduction of the Teenage Pregnancy Strategy (TPS), England's under-18 conception rate has fallen by 55%, but a continued focus on prevention is needed to maintain and accelerate progress. The teenage birth rate remains higher in the UK than comparable Western European countries. Previous trials indicate that school-based social marketing interventions are a promising approach to addressing teenage pregnancy and improving sexual health. Such interventions are yet to be trialled in the UK. This study aims to optimise and establish the feasibility and acceptability of one such intervention: Positive Choices. Methods: Design: Optimisation, feasibility testing and pilot cluster randomised trial.Interventions: the Positive Choices intervention comprises a student needs survey, a student/staff led School Health Promotion Council (SHPC), a classroom curriculum for year nine students covering social and emotional skills and sex education, student-led social marketing activities, parent information and a review of school sexual health services.Systematic optimisation of Positive Choices will be carried out with the National Children's Bureau Sex Education Forum (NCB SEF), one state secondary school in England and other youth and policy stakeholders.Feasibility testing will involve the same state secondary school and will assess progression criteria to advance to the pilot cluster RCT.Pilot cluster RCT with integral process evaluation will involve six different state secondary schools (four interventions and two controls) and will assess the feasibility and utility of progressing to a full effectiveness trial.The following outcome measures will be trialled as part of the pilot:Self-reported pregnancy and unintended pregnancy (initiation of pregnancy for boys) and sexually transmitted infections,Age of sexual debut, number of sexual partners, use of contraception at first and last sex and non-volitional sexEducational attainmentThe feasibility of linking administrative data on births and termination to self-report survey data to measure our primary outcome (unintended teenage pregnancy) will also be tested. Discussion: This will be the first UK-based pilot trial of a school-wide social marketing intervention to reduce unintended teenage pregnancy and improve sexual health. If this study indicates feasibility and acceptability of the optimised Positive Choices intervention in English secondary schools, plans will be initiated for a phase III trial and economic evaluation of the intervention. Trial registration: ISRCTN registry (ISCTN12524938. Registered 03/07/2017).

BACKGROUND: Extensive research effort shows that weight management programmes (WMPs) targeting both diet and exercise are broadly effective. However, the critical features of WMPs remain unclear. OBJECTIVE: to develop a deeper understanding of WMPs critical features, we undertook a systematic review of qualitative evidence. We sought to understand from a service-user perspective how programmes are experienced, and may be effective, on the ground. SEARCH STRATEGY: We identified qualitative studies from existing reviews and updated the searches of one review. INCLUSION CRITERIA: We included UK studies capturing the views of adult WMP users. DATA EXTRACTION AND SYNTHESIS: Thematic analysis was used inductively to code and synthesize the evidence. MAIN RESULTS: Service users were emphatic that supportive relationships, with service providers or WMP peers, are the most critical aspect of WMPs. Supportive relationships were described as providing an extrinsic motivator or "hook" which helped to overcome barriers such as scepticism about dietary advice or a lack confidence to engage in physical activity. DISCUSSION AND CONCLUSIONS: the evidence revealed that service-users' understandings of the critical features of WMPs differ from the focus of health promotion guidance or descriptions of evaluated programmes which largely emphasize educational or goal setting aspects of WMPs. Existing programme guidance may not therefore fully address the needs of service users. The study illustrates that the perspectives of service users can reveal unanticipated intervention mechanisms or underemphasized critical features and underscores the value of a holistic understanding about "what happens" in complex psychosocial interventions such as WMPs.

BACKGROUND: Analysis of specific drug use patterns in men who have sex with men (MSM) is important in targeting HIV prevention and harm reduction interventions and in developing a fuller picture of drug use in context beyond consideration of use of specific drugs in isolation. OBJECTIVES: We sought to develop a typology of recent drug use in MSM, and to explore how distribution of MSM across the classes in this typology differs by socio-sexual characteristics. METHODS: We examined last-year drug use reported by 16,814 MSM as part of a cross-sectional, internet-based survey of MSM living in the UK for which data were collected in late summer 2014. We tested models with between two and six classes for types of specific drug use, and related socio-sexual covariates to the classes in the best model using multinomial regression. RESULTS: Our five-class model described a range of drug use patterns, including minimal users, low-threshold users, old-skool users, chemsex-plus users and diverse users. MSM identifying as gay were more likely to not be minimal users. HIV-positive MSM were more likely to be chemsex-plus users than HIV-negative MSM. Number and type of non-steady partners, ethnicity and education were each related to class membership, though trends were complex. CONCLUSIONS: Findings from associations between correlates and latent classes suggest avenues for service development beyond current attention to opiates or chemsex drugs. Our findings draw attention to heterogeneity in drug use patterns in MSM beyond what current discourse on chemsex drugs would suggest.

BACKGROUND: Previous systematic reviews of weight management programmes (WMPs) have not been able to account for heterogeneity of effectiveness within programmes using top-down behavioural change taxonomies. This could be due to overlapping causal pathways to effectiveness (or lack of effectiveness) in these complex interventions. Qualitative comparative analysis (QCA) can help identify these overlapping pathways. METHODS: Using trials of adult WMPs with dietary and physical activity components identified from a previous systematic review, we selected the 10 most and 10 least effective interventions by amount of weight loss at 12 months compared to minimal treatment. Using intervention components suggested by synthesis of studies of programme user views, we labelled interventions as to the presence of these components and, using qualitative comparative analysis, developed pathways of component combinations that created the conditions sufficient for interventions to be most effective and least effective. RESULTS: Informed by the synthesis of views studies, we constructed 3 truth tables relating to quality of the user-provider relationship; perceived high need for guidance from providers; and quality of the relationship between peers in weight management programmes. We found effective interventions were characterized by opportunities to develop supportive relationships with providers or peers, directive provider-led goal setting and components perceived to foster self-regulation. CONCLUSIONS: Although QCA is an inductive method, this innovative approach has enabled the identification of potentially critical aspects of WMPs, such as the nature of relationships within them, which were previously not considered to be as important as more concrete content such as dietary focus.

BACKGROUND: Posttraumatic stress (PTS) results in significant distress or functional impairment. Prevalence studies report higher rates of PTS in forcibly displaced children (FDC). Current evidence deriving mainly from cross-sectional studies is unable to make causal attributions. Given rising rates of forcible displacement reported by the United Nations High Commissioner for Refugees (UNHCR) in 2014, there is increasing need to determine the best policies and practice for engaging mental health needs of FDC. METHODS: This systematic review identifies (1) longitudinal risk and protective factors and correlates for PTS and (2) its natural history in FDC, contributing to research identifying vulnerable subgroups and malleable factors for PTS and understanding its natural history. No meta-analysis was conducted due to heterogeneity; results were analyzed through narrative synthesis. RESULTS: Eleven longitudinal studies were identified. All but one were prospective cohort designs. They identified prevalence rates between 20% and 48.7% at baseline, 10% and 48.3% at 1 year ( k = 7), 18% and 48% at 2-3 years ( k = 2), 8% and 38% at 6 years ( k = 2), and 35% at 12 years using nine measurement methods in seven independent samples. Evidence from multiple associations supported the following risk factors: exposure to traumatic stressors or other stress, older age, and prior psychopathology. Evidence predominantly supported the stability of PTS with some decline. CONCLUSION: While results should be interpreted with caution given small or unrepresentative samples, they suggest regular mental health screenings should be conducted for FDC, who are a vulnerable subgroup with variable onset and remission. Risk associations with prior psychopathology also suggest that screening upon arrival may be advisable for early intervention and prevention.

BACKGROUND: Alcohol consumption is influenced by a complex causal system of interconnected psychological, behavioural, social, economic, legal and environmental factors. These factors are shaped by governments (eg, licensing laws and taxation), by consumers (eg, patterns of alcohol consumption drive demand) and by alcohol industry practices, such as advertising. The marketing and advertising of alcoholic products contributes to an 'alcogenic environment' and is a modifiable influence on alcohol consumption and harm. The public health perspective is that there is sufficient evidence that alcohol advertising influences consumption. The alcohol industry disputes this, asserting that advertising only aims to help consumers choose between brands. METHODS: We review the evidence from recent systematic reviews, including their theoretical and methodological assumptions, to help understand what conclusions can be drawn about the relationships between alcohol advertising, advertising restrictions and alcohol consumption. CONCLUSIONS: a wide evidence base needs to be drawn on to provide a system-level overview of the relationship between alcohol advertising, advertising restrictions and consumption. Advertising aims to influence not just consumption, but also to influence awareness, attitudes and social norms; this is because advertising is a system-level intervention with multiple objectives. Given this, assessments of the effects of advertising restrictions which focus only on sales or consumption are insufficient and may be misleading. For this reason, previous systematic reviews, such as the 2014 Cochrane review on advertising restrictions (Siegfried et al) contribute important, but incomplete representations of 'the evidence' needed to inform the public health case for policy decisions on alcohol advertising. We conclude that an unintended consequence of narrow, linear framings of complex system-level issues is that they can produce misleading answers. Systems problems require systems perspectives.

BACKGROUND: at the time of publication of the most recent National Institute for Health and Care Excellence (NICE) guidance [technology appraisal (TA) 32] in 2002 on beta-interferon (IFN-β) and glatiramer acetate (GA) for multiple sclerosis, there was insufficient evidence of their clinical effectiveness and cost-effectiveness. OBJECTIVES: to undertake (1) systematic reviews of the clinical effectiveness and cost-effectiveness of IFN-β and GA in relapsing-remitting multiple sclerosis (RRMS), secondary progressive multiple sclerosis (SPMS) and clinically isolated syndrome (CIS) compared with best supportive care (BSC) and each other, investigating annualised relapse rate (ARR) and time to disability progression confirmed at 3 months and 6 months and (2) cost-effectiveness assessments of disease-modifying therapies (DMTs) for CIS and RRMS compared with BSC and each other. REVIEW METHODS: Searches were undertaken in January and February 2016 in databases including the Cochrane Library, MEDLINE and the Science Citation Index. We limited some database searches to specific start dates based on previous, relevant systematic reviews. Two reviewers screened titles and abstracts with recourse to a third when needed. The Cochrane tool and the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) and Philips checklists were used for appraisal. Narrative synthesis and, when possible, random-effects meta-analysis and network meta-analysis (NMA) were performed. Cost-effectiveness analysis used published literature, findings from the Department of Health's risk-sharing scheme (RSS) and expert opinion. A de novo economic model was built for CIS. The base case used updated RSS data, a NHS and Personal Social Services perspective, a 50-year time horizon, 2014/15 prices and a discount rate of 3.5%. Outcomes are reported as incremental cost-effectiveness ratios (ICERs). We undertook probabilistic sensitivity analysis. RESULTS: in total, 6420 publications were identified, of which 63 relating to 35 randomised controlled trials (RCTs) were included. In total, 86% had a high risk of bias. There was very little difference between drugs in reducing moderate or severe relapse rates in RRMS. All were beneficial compared with BSC, giving a pooled rate ratio of 0.65 [95% confidence interval (CI) 0.56 to 0.76] for ARR and a hazard ratio of 0.70 (95% CI, 0.55 to 0.87) for time to disability progression confirmed at 3 months. NMA suggested that 20 mg of GA given subcutaneously had the highest probability of being the best at reducing ARR. Three separate cost-effectiveness searches identified > 2500 publications, with 26 included studies informing the narrative synthesis and model inputs. In the base case using a modified RSS the mean incremental cost was £31,900 for pooled DMTs compared with BSC and the mean incremental quality-adjusted life-years (QALYs) were 0.943, giving an ICER of £33,800 per QALY gained for people with RRMS. In probabilistic sensitivity analysis the ICER was £34,000 per QALY gained. In sensitivity analysis, using the assessment group inputs gave an ICER of £12,800 per QALY gained for pooled DMTs compared with BSC. Pegylated IFN-β-1 (125 µg) was the most cost-effective option of the individual DMTs compared with BSC (ICER £7000 per QALY gained); GA (20 mg) was the most cost-effective treatment for CIS (ICER £16,500 per QALY gained). LIMITATIONS: Although we built a de novo model for CIS that incorporated evidence from our systematic review of clinical effectiveness, our findings relied on a population diagnosed with CIS before implementation of the revised 2010 McDonald criteria. CONCLUSIONS: DMTs were clinically effective for RRMS and CIS but cost-effective only for CIS. Both RCT evidence and RSS data are at high risk of bias. Research priorities include comparative studies with longer follow-up and systematic review and meta-synthesis of qualitative studies. STUDY REGISTRATION: This study is registered as PROSPERO CRD42016043278. FUNDING: the National Institute for Health Research Health Technology Assessment programme.

OBJECTIVE: to systematically review studies of TB treatment experiences in immigrant populations, using Critical Interpretive Synthesis (CIS). METHODS: on 26 October 2014, MEDLINE, CINAHL, Embase, LILACS, and PsycINFO were systematically searched. Grey literature and reference lists were hand-searched. Initial papers included were restricted to studies of immigrant patient perspectives; after a model was developed, a second set of papers was included to test the emerging theory. RESULTS: of 1761 studies identified in the search, a total of 29 were included in the synthesis. Using those studies, we developed a model that suggested treatment experiences were strongly related to the way both individuals and societies adjusted to immigration ('acculturation strategies'). Relationships with healthcare workers and immigration policies played particularly significant roles in TB treatment. CONCLUSIONS: This review emphasised the roles of repatriation policy and healthcare workers in forming experiences of TB treatment in immigrant populations.

Epidemiological evidence for the encounter-level association between sexualised drug use and unprotected anal intercourse in men who have sex with men is unclear and has not examined men who have sex with men in England. To estimate this association, we compared dyadic sexual encounters within respondents. We used encounter-level data from a longitudinal online survey of men who have sex with men living in England and multilevel models to test univariate and multivariate associations between any respondent or partner drug use, specific respondent drug use, additional situational characteristics and unprotected anal intercourse. Based on 6742 encounters from 2142 men who have sex with men, respondent drug use and respondent use of certain specific drugs were associated with increased unprotected anal intercourse odds. In univariate models, partner drug use was associated with increased unprotected anal intercourse odds, but in multivariate models, only non-specific knowledge of partner drug use was associated with the same. Encounters with non-regular-and-steady partners or that were not HIV-seroconcordant were associated with decreased unprotected anal intercourse odds. This is the first within-subjects comparison of drug use and unprotected anal intercourse conducted on a sample from England, and the largest of its kind. Findings are consistent with other studies, though associations between drug use and unprotected anal intercourse are shaped by social contexts that may change over time.

OBJECTIVES: to examine ethnic group differences in HIV testing and sexual behaviours among a large sample of gay and bisexual men (GBM), 13�
years after similar observations were made, assess national HIV prevention responses and inform planning priorities. METHODS: Cross-sectional convenience self-completion online survey in summer 2014, designed and recruited in collaboration with community-based health promoters and gay internet services; comparison with earlier findings reporting on similarly designed survey in 2001. RESULTS: We recruited 15�
388 GBM living in England who self-reported as follows: 18.5% from ethnic minorities; 9.0% tested HIV positive (cf. 17.0% and 5.4% in 2001). Compared with the white British, Asian men were no longer less likely to report diagnosed HIV but had an equal probability of doing so (2001 OR=0.32, 95% CI 0.13 to 0.79; 2014 OR=1.04, 95% CI 0.71 to 1.54); black men remained significantly more likely to report diagnosed HIV (2001 OR=2.06, 95% CI 1.56 to 3.29; 2014 OR=1.62, 95% CI 1.10 to 2.36) as did men in the other white group (2001 OR=1.54, 95% CI 1.23 to 1.93; 2014 OR=1.31, 95% CI 1.10 to 1.55). Overall annual incidence of reported HIV diagnoses in 2014 was 1.1%. Black men were significantly more likely to report diagnosis with HIV in the last 12�
months than the white British (adjusted odds ratios (AOR) 2.57, 95% CI 1.22 to 5.39). No minority ethnic group was more or less likely to report condom unprotected anal intercourse (CUAI) in the last year but men in the Asian, black and all others groups were more likely than the white British to report CUAI with more than one non-steady partners. CONCLUSIONS: Among GBM in England, HIV prevalence continues to be higher among black men and other white men compared with the white British. The protective effect of being from an Asian background appears no longer to pertain. Sexual risk behaviours may account for some of these differences.

In the first paper in this Series we assessed theoretical and empirical evidence and concluded that the health of people living in slums is a function not only of poverty but of intimately shared physical and social environments. In this paper we extend the theory of so-called neighbourhood effects. Slums offer high returns on investment because beneficial effects are shared across many people in densely populated neighbourhoods. Neighbourhood effects also help explain how and why the benefits of interventions vary between slum and non-slum spaces and between slums. We build on this spatial concept of slums to argue that, in all low-income and-middle-income countries, census tracts should henceforth be designated slum or non-slum both to inform local policy and as the basis for research surveys that build on censuses. We argue that slum health should be promoted as a topic of enquiry alongside poverty and health.

Using Toulmin's argumentation theory, we analysed the texts of systematic reviews in the area of workplace health promotion to explore differences in the modes of reasoning embedded in reports of narrative synthesis as compared with reports of meta-analysis. We used framework synthesis, grounded theory and cross-case analysis methods to analyse 85 systematic reviews addressing intervention effectiveness in workplace health promotion. Two core categories, or 'modes of reasoning', emerged to frame the contrast between narrative synthesis and meta-analysis: practical-configurational reasoning in narrative synthesis ('what is going on here? What picture emerges?') and inferential-predictive reasoning in meta-analysis ('does it work, and how well? Will it work again?'). Modes of reasoning examined quality and consistency of the included evidence differently. Meta-analyses clearly distinguished between warrant and claim, whereas narrative syntheses often presented joint warrant-claims. Narrative syntheses and meta-analyses represent different modes of reasoning. Systematic reviewers are likely to be addressing research questions in different ways with each method. It is important to consider narrative synthesis in its own right as a method and to develop specific quality criteria and understandings of how it is carried out, not merely as a complement to, or second-best option for, meta-analysis. © 2016 the Authors.

Child physical abuse is an issue of global concern. Conservative estimates set global prevalence of this type of maltreatment at 25%, its consequences and cost to society escalating with increasing frequency and severity of episodes. Syntheses of the evidence on parenting programs for reducing rates of physical abuse recidivism have, to date, not been able to establish effectiveness. Paucity of data and inconsistent inclusion criteria in past reviews made meta-analysis often impossible or uninformative. The current systematic review updates prior reviews and overcomes some of the methodological issues they encountered by pooling trial-level data from a well-defined scope of trials of parenting interventions aimed at preventing the re-abuse of children by parents with substantiated or suspected physical abuse history. Randomized controlled trials and rigorous non-randomized designs were sought via nine online databases, two trial registries, several clearinghouses and contact with experts. A total of fourteen studies of variable quality were included in this review, four of which had outcomes that enabled meta-analysis. Overall, this review presents evidence supporting the effectiveness of parenting behavioral programs based on social learning theory for reducing hard markers of child physical abuse recidivism. Meta-analysis found that the absolute risk reduction in risk of recidivism was 11 percentage points less for maltreating parents who undergo parenting programs (RD = -0.11, 95% CI [-0.22, -0.004], p = 0.043, I 2 = 28.9%). However, the pooled effect size was not statistically significant when calculated as a risk ratio (0.76, 95% CI [0.54, 1.07], I 2 = 38.4%). Policy makers and practitioners should be made aware that this intervention method is backed by promising evidence featuring modest yet significant reductions in hard markers of child physical abuse, even though the methodological robustness of these findings should be further explored in future research.

The association between poverty and HIV/AIDS in Sub-Saharan Africa remains contested. A better understanding of the relationship between the prevalence of poverty and the disease is essential for addressing prevention, treatment, and care. The present study interrogates this relationship, using a cross-sectional survey of 2477 households in urban and rural KwaZulu-Natal, South Africa. Structural equation modelling was employed to estimate the correlations between poverty and AIDS illness. The analysis revealed a correlation of rpb = 0.23, denoting that a higher level of household poverty was associated with a higher likelihood of being AIDS-unwell. Post hoc t-test showed that receipt of a disability grant by AIDS-affected households was associated with significantly lower poverty, compared to AIDS-affected households not receiving the grant, t(654) = 3.67, p 

Massive slums have become major features of cities in many low-income and middle-income countries. Here, in the first in a Series of two papers, we discuss why slums are unhealthy places with especially high risks of infection and injury. We show that children are especially vulnerable, and that the combination of malnutrition and recurrent diarrhoea leads to stunted growth and longer-term effects on cognitive development. We find that the scientific literature on slum health is underdeveloped in comparison to urban health, and poverty and health. This shortcoming is important because health is affected by factors arising from the shared physical and social environment, which have effects beyond those of poverty alone. In the second paper we will consider what can be done to improve health and make recommendations for the development of slum health as a field of study.

Female sex work accounts for about 15% of the global HIV burden in women. Asia is the region with the second highest attributable fraction of the HIV epidemic after sub-Saharan Africa. This review synthesises studies that depict the barriers and facilitators encountered by sex workers in Asia when negotiating consistent condom use. A total of 18 studies published between January 1989 and May 2015 were included in the review. Data were extracted, critically appraised and analysed using a thematic analysis approach. Individual-level factors related to sex workers' knowledge, perception and power, as well as interpersonal-level factors that encompassed dynamics with clients and peer-related factors, presented as both barriers and facilitators to sex workers' condom negotiation process. In addition, the structural environment of sex work, access to resources, poverty, stigma, the legal environment and the role of media were also identified as factors in influencing the condom negotiation process of sex workers. A multisectoral interventional approach that addresses the multilevel barriers encountered by sex workers in condom negotiation is needed. Awareness of safe-sex practice should be collectively enhanced among sex workers, clients and brothel managers.

UNLABELLED: Background Although many within-subjects comparisons conducted on samples of men who have sex with men have sought to understand the association between specific situational characteristics (e.g. drug use or location of sex) and sexual risk behaviour, none have considered the 'clustering' of patterns of situational characteristics. An initial typology of sexual encounters is derived and the relationship of this typology to condomless anal intercourse (CAI) and pleasure is tested. METHODS: Data from a longitudinal survey of men who have sex with men living in England were used. Multilevel latent class analyses were estimated to determine an optimal class solution on the situational characteristics, and then pseudo-imputation was used to estimate the association between class and both CAI and pleasure. RESULTS: a three-class solution fit the data best, with a scaled relative entropy of 92.4%. Classes were characterised as featuring: regular steady partners in private locations with low drug use (class 1), casual partners with increased probability of sex occurring in a sex-on-premises venue (class 2), and high levels of polydrug use together with increased probability of casual partners (class 3). Encounters were different both in pairwise comparisons and overall on probability of CAI. They were different overall but not necessarily pairwise on pleasure. CONCLUSIONS: These initial findings demonstrate the possibility of understanding sexual encounters in terms of the contexts, or classes, within which they occur. This may have implications for tailoring HIV prevention to specific encounter types. Future research should seek to extend encounter-level typologies to specific drug use variables.

OBJECTIVES: This nested cross-sectional study of dyadic sexual encounters with new male partners reported by men living in England who have sex with men tested moderation between drug use and location of sex in associations with unprotected anal intercourse (UAI). METHODS: Data were drawn from two waves of a longitudinal monthly internet survey of men living in England who have sex with men conducted in 2011. Using generalised estimating equations and logit link, we tested the relationship with UAI of any respondent drug use before sex, specific respondent drug use before sex, location of sex (distinguishing private, sex-on-premises venue and cruising locations) and location-drug use interactions. RESULTS: Any respondent drug use (OR 1.57, 95% CI 1.31 to 1.88) was associated with increased odds of UAI. Relative to encounters in private locations, encounters in sex-on-premises venues (0.69, 95% CI 0.52 to 0.91), but not cruising locations, were associated with decreased odds of UAI. Any respondent drug use, respondent use of poppers and respondent use of alcohol were each associated with increased UAI in sex-on-premises venues. DISCUSSION: This analysis presents evidence of moderation between drug use and location of sex in associations with UAI. Though this analysis used a large sample, it relied on community-recruited respondents. Our findings may reflect either 'totalising' effects of drug use across venues or site-specific use of drugs as a mechanism for cognitive escape. Additional qualitative research is necessary to understand these findings in context.

OBJECTIVES: the British HIV Association's (BHIVA) testing guidelines recommend men who have sex with men (MSM) test annually or more frequently if ongoing risk is present. We identify which groups of MSM in England are less likely to have tested for HIV and their preferences for future tests by testing model, in order to inform health promotion programmes. METHODS: Data come from the Gay Men's Sex Survey 2014, a cross-sectional survey of MSM, aged 16�
years or older and living in the UK. Only men who did not have diagnosed HIV and were living in England were included in this analysis. We used logistic regression models to understand how social determinants of health were associated with not testing for HIV in the past 12�
months, and never having tested. We then cross-tabulated preferred testing location by demographic characteristics. RESULTS: Younger men, older men and men who were not gay identified were least likely to have tested for HIV. Higher educational attainment, migrancy, Black ethnicity and being at higher of risk were associated with greater levels of HIV testing. Men who were less likely to have tested for HIV preferred a wider range of options for future HIV testing. CONCLUSIONS: If the BHIVA's HIV testing policy of 2008 was used to guide testing priorities among MSM focus would be on increasing the rate of annual testing among MSM at less risk of HIV (ie, younger men, older men and non-gay identified MSM). Instead the promotion of more frequent testing among the groups most at risk of infection should be prioritised in order to reduce the time between infection and diagnosis.

BACKGROUND: While the efficacy and effectiveness of brief interventions for alcohol (ABI) have been demonstrated in primary care, there is weaker evidence in other settings and reviews do not consider differences in content. We conducted a systematic review to measure the effect of ABIs on alcohol consumption and how it differs by the setting, practitioner group and content of intervention. METHODS: We searched MEDLINE, EMBASE, PsycINFO; CINAHL, Social Science Citation Index, Cochrane Library and Global Health up to January 2015 for randomised controlled trials that measured effectiveness of ABIs on alcohol consumption. We grouped outcomes into measures of quantity and frequency indices. We used multilevel meta-analysis to estimate pooled effect sizes and tested for the effect of moderators through a multiparameter Wald test. Stratified analysis of a subset of quantity and frequency outcomes was conducted as a sensitivity check. RESULTS: 52 trials were included contributing data on 29�
891 individuals. ABIs reduced the quantity of alcohol consumed by 0.15 SDs. While neither the setting nor content appeared to significantly moderate intervention effectiveness, the provider did in some analyses. Interventions delivered by nurses had the most effect in reducing quantity (d=-0.23, 95% CI (-0.33 to -0.13)) but not frequency of alcohol consumption. All content groups had statistically significant mean effects, brief advice was the most effective in reducing quantity consumed (d=-0.20, 95% CI (-0.30 to -0.09)). Effects were maintained in the stratified sensitivity analysis at the first and last assessment time. CONCLUSIONS: ABIs play a small but significant role in reducing alcohol consumption. Findings show the positive role of nurses in delivering interventions. The lack of evidence on the impact of content of intervention reinforces advice that services should select the ABI tool that best suits their needs.

PURPOSE OF REVIEW: Illicit drug use before or during sex - known as sexualized drug use (colloquially 'chemsex' or 'party and play') - has evolved as novel psychoactive substances have entered the market in many parts of the world. Here, we review key conceptual issues in associations between illicit drug use and sexual risk-behaviour in MSM. RECENT FINDINGS: Although many studies have confirmed that MSM use drugs with greater prevalence than the general population, evidence is of variable quality and a sampling frame is difficult to establish. Moreover, psychosocial hypotheses linking drug use and sexual risk, including cognitive escape and sensation seeking, are unsatisfactory and generally ignore strategic use of drugs for sexual aims. Person-level associations between drug use history and both sexual risk behaviour and HIV infection tend to be consistent around the world, but evidence comparing encounters within subjects is generally unclear and out of date. SUMMARY: There is a need for interventions for harm reduction targeted at MSM that account specifically for the social and cultural contexts of sexualized drug use. Expanded attention to surveillance of emerging drug use trends can help clinicians in sexual health and infectious diseases best anticipate the needs of their service users.

To understand associations between location of sex and sexual risk, it is most helpful to compare sexual encounters within persons. We systematically reviewed within-subjects comparisons of sexual encounters reported by men who have sex with men (MSM) with respect to location of sex. Within-subjects comparisons of sexual risk and location of sex were eligible if they collected data post-1996 from samples of MSM. We independently screened results and full-text records in duplicate. of 6,336 deduplicated records, we assessed 138 full-text studies and included six, most of which compared unprotected anal intercourse against other anal intercourse. This small, but high quality, body of evidence suggests that associations between attendance at sex-on-premises venues and person-level sexual risk may be due to overall propensity towards unprotected sex. However, there may be some location factors that promote or are associated with serononconcordant unprotected anal intercourse. Health promoters may wish to focus on person-level characteristics.

BACKGROUND: Complex or heterogeneous data pose challenges for systematic review and meta-analysis. In recent years, a number of new methods have been developed to meet these challenges. This qualitative interview study aimed to understand researchers' understanding of complexity and heterogeneity and the factors which may influence the choices researchers make in synthesising complex data. METHODS: We conducted interviews with a purposive sample of researchers (N = 19) working in systematic review or meta-analysis across a range of disciplines. We analysed data thematically using a framework approach. RESULTS: Participants reported using a broader range of methods and data types in complex reviews than in traditional reviews. A range of techniques are used to explore heterogeneity, but there is some debate about their validity, particularly when applied post hoc. CONCLUSIONS: Technical considerations of how to synthesise complex evidence cannot be isolated from questions of the goals and contexts of research. However, decisions about how to analyse data appear to be made in a largely informal way, drawing on tacit expertise, and their relation to these broader questions remains unclear.

Previous event-level analyses have often, but not always, found significant associations between drug use and sexual risk behaviour in men who have sex with men (MSM), but these analyses have rarely considered either multipartner encounters specifically, or other sexual outcomes such as pleasure and control. Using data from an internet-based longitudinal survey of MSM, we tested the association between drug use by respondent and by partners and unprotected anal intercourse (UAI), pleasure and control over sexual activity. Overall respondent substance use was significantly associated with increased odds of UAI, though not with pleasure or control. Respondent use of crystal methamphetamine was significantly associated with both increased odds of UAI and decreased odds of control over sexual activity. This analysis agrees with previous studies of dyadic encounters, and specifically suggests that the association between crystal methamphetamine and sexual risk behaviour may be mediated by loss of control.

OBJECTIVES: to investigate the application of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach and the quality of evidence ratings in systematic reviews of complex interventions. STUDY DESIGN AND SETTING: This study examined all 40 systematic reviews published in three Cochrane Review Groups from 2013 to May 2014: Cochrane Developmental, Psychosocial and Learning Problems Group (CDPLPG); Cochrane Public Health Group (CPHG); and Cochrane Depression, Anxiety, and Neurosis Group (CCDAN). The reviews were coded and classified into "complex" (n = 24) and "simple" (n = 16) intervention review groups based on the predefined complexity dimensions from the extant literature mapped into the PICOTS framework. All the data were analyzed in these two groups to help identify specific patterns of the GRADE ratings in the reviews of complex interventions. RESULTS: Outcomes of complex intervention reviews had higher proportions of "very low" quality of evidence ratings compared with those of simple intervention reviews (37.5% vs. 9.1% for the primary benefit outcomes) and were more frequently downgraded for inconsistency, performance bias, and study design. None of the outcomes of complex intervention reviews (0%) were given "high" GRADE ratings. CONCLUSION: Results suggest that the GRADE assessment may not adequately describe the evidence base of complex interventions.

BACKGROUND: Substance use has detrimental short-term and long-term consequences for young people. Positive youth development (PYD) interventions, which favour promotion of positive assets over traditional risk reduction, have received attention recently as a possible intervention to prevent adolescent substance use. We aimed to synthesise the evidence on PYD interventions for reduction in substance use in young people. METHODS: We searched 21 databases, including MEDLINE, PsycINFO, CINAHL and CENTRAL, and hand-searched key journals and websites. We included studies with more than half of participants aged 11-18 years where interventions meeting a pre-specified definition of PYD were delivered in community settings outside of normal school hours and did not target parents or young people with pre-defined conditions. Two reviewers screened records, assessed full-text studies for inclusion, and extracted data. A modified Cochrane risk of bias tool was used for quality assessment. RESULTS: Ten studies reported in 13 reports were included in our synthesis. PYD interventions did not have an effect of statistical or public health significance on any substance use, illicit drug use or alcohol outcomes in young people. CONCLUSIONS: Interventions were diverse in content and delivery. Our review suggests that existing PYD interventions subject to evaluation do not appear to have produced reductions in substance use of public health significance. However, these interventions may not be the best exemplars of a PYD approach. Therefore, our findings should not be taken as evidence for the ineffectiveness of PYD as a theory of change for reducing substance use among young people. Additional rigorous evaluation of PYD interventions is key before further investment. Evaluations were of highly variable quality. Though searches were extensive, we were unable to test for publication bias.

BACKGROUND: We systematically reviewed and meta-analysed evaluations testing the effectiveness of positive youth development (PYD) interventions for reducing violence in young people. METHODS: Two reviewers working independently screened records, assessed full-text studies for inclusion and extracted data. Outcomes were transformed to Cohen's d. Quality assessment of included evaluations was undertaken using the Cochrane risk of bias tool. Effect sizes were combined using multilevel meta-analysis. We searched 21 databases, including MEDLINE, PsycINFO, CINAHL and CENTRAL, and hand-searched key journals and websites. We included studies where the majority of participants were aged 11-18�
years and where interventions were delivered in community (not clinical or judicial) settings outside of normal school hours. We excluded studies targeting predefined physical and mental health conditions or parents/carers alongside young people. We defined violence as perpetration or victimisation of physical violence including violent crime. RESULTS: Three randomised trials were included in this systematic review. Included evaluations each had design flaws. Meta-analyses suggested that PYD interventions did not have a statistically significant effect on violence outcomes across all time points (d=0.021, 95% CI -0.050 to 0.093), though interventions did have a statistically significant short-term effect (d=0.076, 95% CI 0.013 to 0.140). CONCLUSIONS: Our meta-analyses do not offer evidence of PYD interventions in general having effects of public health significance in reducing violence among young people. Evaluations did not consistently report theories of change or implementation fidelity, so it is unclear if our meta-analyses provide evidence that the PYD theory of change is ineffective in reducing violence among young people.

BACKGROUND: Foreign-born populations carry a significant TB burden in low-prevalence countries, composing over half of all cases in parts of Europe and North America. This study systematically reviewed evidence of risk factors for nonadherence to TB drug therapy in this group. METHODS: on 28 October 2013 MEDLINE, CINAHL, Embase, PsychINFO and ProQuest were systematically searched for studies examining adherence in foreign-born populations with TB. Grey literature and reference lists were hand-searched. Risk factor studies were selected for inclusion if they consisted of at least 95% foreign-born populations. RESULTS: of 1761 studies identified in the search, 20 were included in the risk factor review. Undocumented immigration status, older age, and social risk factors were consistently correlated with nonadherence; gender, ethnicity, immigration time, education level, adverse side effects, and HIV status were inconsistently correlated; and behavioural risk factors and marital status were consistently not correlated. CONCLUSIONS: This review emphasizes documentation status as a risk factor candidate for further investigation.

OBJECTIVE: Children's disruptive behavior problems place children at high risk for oppositional defiant disorder and conduct disorder, and carry a high burden for individuals and society. Policy makers and service providers aiming to reduce children's disruptive behavior problems must often choose between importing an intervention developed abroad or instead developing or using a "homegrown" (i.e. local) intervention. No comprehensive comparison of these interventions exists. METHOD: We performed a multilevel meta-regression of 129 randomized trials (374 effect sizes) of transported and homegrown parenting interventions. We identified trials by searching the included trials lists of systematic reviews, found through searches in 6 databases (e.g. MEDLINE, EMBASE). Trials that had not yet been reviewed were found by searching the same databases. Primary outcome was the mean difference in effectiveness between transported and homegrown interventions to reduce disruptive child behavior. We also compared this differential effectiveness for various intervention "brands" (e.g. Incredible Years and Triple P Positive Parenting Program) and geographical regions (e.g. North America and Europe). RESULTS: Transported and homegrown interventions did not differ in their effectiveness to reduce disruptive child behavior (d = 0.10, not significant). Results were robust across intervention brands and geographical regions. Six trials on transported interventions in Hong Kong, Iran, and Panama suggest promising results for transporting interventions to "nonwestern" countries, whereas one trial in Indonesia does not. CONCLUSION: Parenting interventions based on the same principles led to similar outcomes, whether transported or homegrown. This finding supports the selection of interventions based on their evidence base rather than on cultural specificity.

OBJECTIVES: to explore user perspectives on applying the Grading of Recommendations Assessment, Development and Evaluation (GRADE) to systematic reviews of complex interventions. STUDY DESIGN AND SETTING: Thirty-three authors of recent (2013 onward) systematic reviews were contacted regarding their perspectives on using GRADE from three Cochrane review groups: Cochrane Developmental, Psychosocial, and Learning Problems Group; Cochrane Public Health Group; and Cochrane Depression, Anxiety, and Neurosis Group. Framework Analysis was applied to the data to identify the challenges in applying GRADE and suggestions for its extension, that is, adaptation. These two themes were cross-compared between the groups of answers from "simple" vs. "complex" intervention review authors to identify the specific perspectives on using GRADE in reviews of complex interventions. RESULTS: Specific challenges were identified in applying GRADE to reviews of complex interventions. These were related to the assessment of nonrandomized studies and performance bias in GRADE. Authors perceived these challenges to contribute to frequent downgrading of the "best evidence possible" for complex interventions. Meanwhile, GRADE was found to lack an analytic approach to enable adequate evidence synthesis and assessment of intervention implementation elements. CONCLUSION: Users suggest that the GRADE guidance be extended to address-specific considerations for complex interventions.

BACKGROUND: Preventing adolescent substance use and youth violence are public health priorities. Positive youth development interventions are widely deployed often with the aim of preventing both. However, the theorised mechanisms by which PYD is intended to reduce substance use and violence are not clear and existing evaluated interventions are under-theorised. Using innovative methods, we systematically searched for and synthesised published theoretical literature describing what is meant by positive youth development and how it might reduce substance use and violence, as part of a broader systematic review examining process and outcomes of PYD interventions. METHODS: We searched 19 electronic databases, review topic websites, and contacted experts between October 2013 and January 2014. We included studies written in English, published since 1985 that reported a theory of change for positive youth development focused on prevention of smoking, alcohol consumption, drug use or violence in out-of-school settings. Studies were independently coded and quality-assessed by two reviewers. RESULTS: We identified 16 studies that met our inclusion criteria. Our synthesis suggests that positive youth development aims to provide youth with affective relationships and diverse experiences which enable their development of intentional self-regulation and multiple positive assets. These in turn buffer against or compensate for involvement in substance use and violence. Existing literature is not clear on how intentional self-regulation is developed and which specific positive assets buffer against substance use or violence. CONCLUSIONS: Our synthesis provides: an example of a rigorous systematic synthesis of theory literature innovatively applying methods of qualitative synthesis to theoretical literature; a clearer understanding of how PYD might reduce substance use and violence to inform future interventions and empirical evaluations.

Although it might be assumed that most public health programmes involving social or behavioural rather than clinical interventions are unlikely to be iatrogenic, it is well established that they can sometimes cause serious harms. However, the assessment of adverse effects remains a neglected topic in evaluations of public health interventions. In this paper, we first argue for the importance of evaluations of public health interventions not only aiming to examine potential harms but also the mechanisms that might underlie these harms so that they might be avoided in the future. Second, we examine empirically whether protocols for the evaluation of public health interventions do examine harmful outcomes and underlying mechanisms and, if so, how. Third, we suggest a new process by which evaluators might develop 'dark logic models' to guide the evaluation of potential harms and underlying mechanisms, which includes: theorisation of agency-structure interactions; building comparative understanding across similar interventions via reciprocal and refutational translation; and consultation with local actors to identify how mechanisms might be derailed, leading to harmful consequences. We refer to the evaluation of a youth work intervention which unexpectedly appeared to increase the rate of teenage pregnancy it was aiming to reduce, and apply our proposed process retrospectively to see how this might have strengthened the evaluation. We conclude that the theorisation of dark logic models is critical to prevent replication of harms. It is not intended to replace but rather to inform empirical evaluation.

INTRODUCTION: Reciprocal translation, the understanding of one study's findings in terms of another's, is the foundation of most qualitative metasynthetic methods. In light of the proliferation of metasynthesis methods, the current review sought to create a taxonomy of operations of reciprocal translation using recently published qualitative metasyntheses. METHODS: on 19 August 2013, MEDLINE, Embase and PsycINFO were searched. Included articles were full reports of metasyntheses of qualitative studies published in 2012 in English-language peer-reviewed journals. Two reviewers, working independently, screened records, assessed full texts for inclusion and extracted data on methods from each included metasynthesis. Systematic review methods used were summarised, and metasynthetic methods were inductively analysed to develop the taxonomy. RESULTS: of 61 included metasyntheses, 21 (34%) reported fully replicable search strategies and 51 (84%) critically appraised included studies. Based on methods in these metasyntheses, we developed a taxonomy of reciprocal translation with four overlapping categories: visual representation; key paper integration; data reduction and thematic extraction; and line-by-line coding. DISCUSSION: This systematic review presents an update on methods and reporting currently used in qualitative metasynthesis. It also goes beyond the proliferation of approaches to offer a parsimonious approach to understanding how reciprocal translations are accomplished across metasynthetis methods.

AIM: Ageism in health care delivery and nursing poses a fundamental threat to health and society. In this commentary, implications of age discrimination are presented to generate an agenda for action in nursing management. BACKGROUND: in nations like the United States and the United Kingdom, nursing is an ageing profession caring for an ageing society where age discrimination takes many forms and has broad impact. EVALUATION: This commentary critically synthesizes the literature on ageism and relevant data on ageing societies for nurse managers and other leaders. KEY ISSUES: Investigations of ageism suggest that discrimination negatively affects health and results in poor health care experiences. Age discrimination is present in nursing, exacerbating workforce shortages and limiting the use of expertise within the profession. CONCLUSION: Nursing faces a future for which understanding ageing societies and ageism is essential. An agenda for the future is proposed. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers possess the power to enact an agenda for combating ageism in health care and nursing.

BACKGROUND: Multiple interventions meta-analysis has been recommended in the methodological literature as a tool for evidence synthesis when a heterogeneous set of interventions is included in the same review—and, more recently, when a heterogeneous set of complex interventions is included. However, there is little guidance on the use of this method with complex interventions. This article suggests two approaches to model complexity and heterogeneity through this method. DISCUSSION: 'Clinically meaningful units' groups interventions by modality or similar theory of change, whereas 'components and dismantling' separates out interventions into combinations of components and either groups interventions by the combination of components they demonstrate or extracts effects for each identified component and, possibly, interactions between components. Future work in systematic review methodology should aim to understand how to develop taxonomies of components or theories of change that are internally relevant to the studies in these multiple interventions meta-analyses. SUMMARY: Despite little meaningful prior guidance to its use in this context, multiple interventions meta-analysis has the potential to be a useful tool for synthesising heterogeneous sets of complex interventions. Researchers should choose an approach in accordance with their specific aims in their systematic review.

UNLABELLED: Background Internet sex-seeking has been associated at the person level with sexual risk. However, the most robust method of encounter-level inference to determine associations between internet sex-seeking and sexual risk is to compare encounters against each other. We systematically reviewed within-subjects comparisons of sexual encounters that tested associations between internet sex-seeking and sexual risk in men who have sex with men. METHODS: We systematically searched databases on 9 July 2013, then screened records and full-text articles in duplicate and independently. Studies were synthesised narratively. RESULTS: Four studies were included. Although studies were generally of high quality, the findings were inconsistent and did not show clear evidence of a relationship between internet sex-seeking and sexual risk. CONCLUSIONS: Further research in internet sex-seeking among men who have sex with men is required, particularly as internet-enabled sexual sociality continues to evolve. Internet-based health promotion may wish to target person-level features instead of encounter-specific characteristics.

© 2014 the Cochrane Collaboration. This is the protocol for a review and there is no abstract. The objectives are as follows: This review seeks to examine the effectiveness of prevention interventions for MSM that combine at least two of the three categories of intervention modality (biomedical, behavioural and structural) compared either to other HIV prevention interventions or to minimal/no HIV prevention. Below, descriptions of the criteria that will be used to categorise intervention components are provided under the heading Types of interventions' and the full list of outcomes of interest are provided in the section Types of outcome measures'. All planned comparisons are detailed in the section Data synthesis', followed by the planned variables of interest for subgroup and meta-regression analyses.

BACKGROUND: Catholic hospitals play a critical role in the provision of health care in the United States; yet, empirical evidence of patient outcomes in these institutions is practically absent in the literature. PURPOSE: the purpose of this study was to determine whether patient perceptions of care are more favorable in Catholic hospitals as compared with non-Catholic hospitals in a national sample of hospitals. METHODOLOGY: This cross-sectional secondary analysis used linked data from the 2008 American Hospital Association Annual Survey, the 2008 Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, the 2008 Medicare Case Mix Index file, and the 2010 Religious Congregations and Membership Study. The study included over 3,400 hospitals nationwide, including 494 Catholic hospitals. Propensity score matching and ordinary least-squares regression models were used to examine the relationship between Catholic affiliation and various HCAHPS measures. FINDINGS: Our findings revealed that patients treated in Catholic hospitals appear to rate their hospital experience similar to patients treated in non-Catholic hospitals. Catholic hospitals maintain a very slight advantage above their non-Catholic peers on five HCAHPS measures related to nurse communication, receipt of discharge information, quietness of the room at night, overall rating, and recommendation of the hospital; yet, these differences were minimal. PRACTICE IMPLICATIONS: If the survival of Catholic health care services is contingent upon how its provision of care is distinct, administrators of Catholic hospitals must show differences more clearly. Given the great importance of Catholic hospitals to the health of millions of patients in the United States, this study provides Catholic hospitals with a set of targeted areas on which to focus improvement efforts, especially in light of current pay-for-performance initiatives.

Men who have sex with men (MSM) experience disproportionately high rates of HIV and substance use. Though interventions based on cognitive behavioural therapy (CBT) are effective for many psychiatric disorders, systematic reviews of CBT for substance use present mixed results and CBT has not been systematically reviewed for HIV risk reduction in MSM. Randomised controlled trials (RCTs) of non-pharmacological CBT for substance-using MSM were systematically reviewed to assess the evidence for these interventions' impact on unprotected anal intercourse (UAI). We searched 20 databases on 22 September 2012. of the 2801 records identified, both authors separately assessed 70 full-text articles for inclusion. In three included RCTs, one RCT compared CBT against non-treatment control and two RCTs compared CBT against CBT variants. Across studies, CBT led to UAI reductions, though at one-year follow-up, these reductions were generally not greater than in other trial arms. This evidence of moderate quality indicates that while CBT may reduce UAI in substance-using MSM, it is unclear if CBT is more effective than mere assessment. All RCTs tested intensive, clinic-based interventions requiring sustained participant commitment, indicating a need for research into briefer interventions, with particular focus on episodic substance use and effectiveness trials.

BACKGROUND: Previous reviews show that reporting guidelines have improved the quality of trial reports in medicine, yet existing guidelines may not be fully suited for social and psychological intervention trials. OBJECTIVE/DESIGN: We conducted a two-part study that reviewed (1) reporting guidelines for and (2) the reporting quality of social and psychological intervention trials. DATA SOURCES: (1) to identify reporting guidelines, we systematically searched multiple electronic databases and reporting guideline registries. (2) to identify trials, we hand-searched 40 journals with the 10 highest impact factors in clinical psychology, criminology, education, and social work. ELIGIBILITY: (1) Reporting guidelines consisted of articles introducing a checklist of reporting standards relevant to social and psychological intervention trials. (2) Trials reported randomised experiments of complex interventions with psychological, social, or health outcomes. RESULTS: (1) We identified 19 reporting guidelines that yielded 147 reporting standards relevant to social and psychological interventions. Social and behavioural science guidelines included 89 standards not found in CONSORT guidelines. However, CONSORT guidelines used more recommended techniques for development and dissemination compared to other guidelines. (2) Our review of trials (n = 239) revealed that many standards were poorly reported, such as identification as a randomised trial in titles (20% reported the information) and abstracts (55%); information about blinding (15%), sequence generation (23%), and allocation concealment (17%); and details about actual delivery of experimental (43%) and control interventions (34%), participant uptake (25%), and service environment (28%). Only 11 of 40 journals referenced reporting guidelines in "Instructions to Authors." CONCLUSION: Existing reporting guidelines have important limitations in content, development, and/or dissemination. Important details are routinely missing from trial publications; most leading journals in social and behavioural sciences do not ask authors to follow reporting standards. Findings demonstrate a need to develop a CONSORT extension with updated standards for social and psychological intervention trials.
