Prev SciAbstract:
Promoting Learning from Null or Negative Results in Prevention Science Trials.
There can be a tendency for investigators to disregard or explain away null or negative results in prevention science trials. Examples include not publicizing findings, conducting spurious subgroup analyses, or attributing the outcome post hoc to real or perceived weaknesses in trial design or intervention implementation. This is unhelpful for several reasons, not least that it skews the evidence base, contributes to research "waste", undermines respect for science, and stifles creativity in intervention development. In this paper, we identify possible policy and practice responses when interventions have null (ineffective) or negative (harmful) results, and argue that these are influenced by: the intervention itself (e.g. stage of gestation, perceived importance); trial design, conduct, and results (e.g. pattern of null/negative effects, internal and external validity); context (e.g. wider evidence base, state of policy); and individual perspectives and interests (e.g. stake in the intervention). We advance several strategies to promote more informative null or negative effect trials and enable learning from such results, focusing on changes to culture, process, intervention design, trial design, and environment.

Abstract:
Assessing the Feasibility of a Parent Life Coaching Intervention to Support Parents and Children Who Have Experienced Domestic Violence and Abuse
© 2019, the Author(s). Children exposed to domestic violence are at risk for a range of psychosocial difficulties, which may be mitigated by improving their caregiver’s mental health and capacity to parent. Life coaching is a promising behaviour change approach for improving the empowerment, efficacy and well-being of carers who are parenting alone following domestic violence. This study evaluated the feasibility of a novel life coaching programme. Using a pre- post-test design, the Family Vision© (FV) programme was implemented in two community settings. The programme was offered to single mothers with experience of domestic violence. Feasibility data were collected using satisfaction forms, semi-structured interviews and focus groups with parents, facilitators and managers. Mothers’ self-reports about their mental well-being; empowerment and self-efficacy were collected, as well as the quality of their parent-child relationships and children’s psychosocial functioning, using standardised measures at baseline and end of programme. The programme was found to have good acceptability for this population of parents and was considered feasible to deliver in the two community settings where it was piloted. There were indications that women who completed the programme had improved mental well-being, as well as improved empowerment and efficacy by the end of the programme. The FV programme is feasible to implement and could support positive change for single parents with respect to their mental health and capacity to parent effectively. Demonstrated mediators, these effects could also promote children’s health and well-being. Feasibility for a randomised trial and wider scale-up in the community is now required.

Abstract:
Co-occurring change in children's conduct problems and maternal depression: Latent class individual participant data meta-analysis of the Incredible Years parenting program.
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.

Abstract:
Equity effects of parenting interventions for child conduct problems: a pan-European individual participant data meta-analysis.
BACKGROUND: Childhood conduct problems are a costly public health problem and are five times more common in socially disadvantaged groups than they are in advantaged groups. Untreated, conduct problems have a poor prognosis, with increasing gaps between socioeconomic groups, and high rates of subsequent criminality. Incredible Years is a high quality parenting programme for reducing conduct problems and is widely disseminated in Europe. Many trials have shown Incredible Years to be effective but the potential effects of parenting interventions on social inequality are unknown. Some behavioural interventions (eg, smoking cessation programmes), although beneficial overall, can widen inequality gaps. Because single trials and aggregate-level meta-analyses are ill equipped for examining differential intervention (moderator) effects, we pooled individual-level trial data to assess the effects of Incredible Years on social equity. METHODS: We did a systematic review and individual participant data meta-analysis by searching CINAHL, Embase, Global Health, Medline, and PsycINFO, for studies published from inception to March 15, 2019. We also searched the Incredible Years website library and consulted with experts, including the European Incredible Years mentors' network. We included data from all completed randomised trials of the Incredible Years parenting intervention in Europe that included children aged 1-12 years, including unpublished trials, without restriction on publication year or outcome measures. We included prevention (selective or universal) and treatment or indicated prevention trials (for children diagnosed or above the clinical cutoff for conduct problems). We excluded trials or conditions within trials that were not randomised, included additional non-parenting material (eg, child-focused interventions), or were abbreviated, non-standard versions of the usual Incredible Years intervention of 12-14 weekly sessions. We requested individual participant data from the study authors. The primary outcome was child conduct problems, assessed using the Eyberg Child Behavior Inventory Intensity (ECBI-I) scale. Moderators were analysed using multilevel modelling with multiple imputation. FINDINGS: of 15 European trials of Incredible Years parenting programmes (n=1696 children), individual participant data were unavailable for one trial and one trial did not assess the primary outcome. Children were aged 2-10 years (median 5·1), 492 (30%) of 1651 children were from an ethnic minority and 931 (58%) of 1614 were from low-income families. Families who received the Incredible Years intervention reported an overall reduction in child conduct problems (13·5 points on the ECBI-I scale, 95% CI 10·9-16·1). There were no differential effects by family disadvantage (indicated by poverty, lone parenthood, teenage parenthood, household joblessness, or low education), or ethnic minority status. INTERPRETATION: We found no evidence for differential effects by social disadvantage, suggesting that Incredible Years is unlikely to widen socioeconomic inequalities in conduct problems. Furthermore, the programme might be an important tool for reducing social disparities and improving poor long-term outcomes in disadvantaged families because follow-up studies indicate that benefits persist. Clinicians and commissioners can be reassured that the programme is similarly effective for families from different backgrounds. FUNDING: UK National Institute for Health Research.

Experiences of interventions aiming to improve the mental health and well-being of children and young people with a long-term physical condition: a systematic review and meta-ethnography.

Abstract:
Experiences of interventions aiming to improve the mental health and well-being of children and young people with a long-term physical condition: a systematic review and meta-ethnography.
BACKGROUND: Children and young people with long-term physical health conditions are at increased risk of experiencing mental health and well-being difficulties. However, there is a lack of research that explores the experiences of and attitudes towards interventions aiming to improve their mental health and well-being. This systematic review seeks to address this gap in the literature by exploring what children and young people with long-term conditions, their caregivers, and health practitioners perceive to be important aspects of interventions aiming to improve their mental health and well-being. METHODS: an information specialist searched five academic databases using predefined criteria for qualitative evaluations of interventions aiming to improve the mental health or well-being of children with long-term physical conditions. Reviewers also performed supplementary citation and grey literature searches. Two reviewers independently screened titles, abstracts, and full texts that met the inclusion criteria and conducted data extraction and quality assessment. Meta-ethnography was used to synthesize the findings. RESULTS: Screening identified 60 relevant articles. We identified five overarching constructs through the synthesis: (a) Getting in and Staying In, (b) Therapeutic Foundation, (c) Social Support, (d) a Hopeful Alternative, and (e) Empowerment. The line of argument that links these constructs together indicates that when interventions can provide an environment that allows young people to share their experiences and build empathetic relationships, it can enable participants to access social support and increase feelings of hope and empowerment. CONCLUSION: These findings may provide a framework to inform the development of mental health interventions for this population and evaluate existing interventions that already include some of the components or processes identified by this research. Further research is needed to establish which of the constructs identified by the line of argument are most effective in improving the mental well-being of young people living with long-term conditions.

Abstract:
Healthy Parent Carers peer-led group-based health promotion intervention for parent carers of disabled children: protocol for a feasibility study using a parallel group randomised controlled trial design
Abstract
. Background
. Parent carers of disabled children are at increased risk of mental and physical health problems. They often experience challenges to maintaining good health which have implications for their well-being and their ability to care for their children. In response to these needs, researchers and parent carers developed the Healthy Parent Carers (HPC) programme. It is a peer-led, group-based intervention that promotes behaviours associated with health and well-being. The aims of this trial are to assess the acceptability of the HPC programme and the feasibility of its delivery in the community and to assess the feasibility and acceptability of the design of the definitive trial to evaluate the programme’s effectiveness and cost-effectiveness.
.
. Methods
. We will establish six research sites and train facilitators to deliver the manualised intervention. Parent carers of children with special educational needs and disabilities will be individually randomised, stratified by group delivery site, to either take part in a group programme and online resources (intervention) or to receive access to the online resources only (control). Measures of mental health; well-being; health-related quality of life; health behaviours; patient activation; protective factors such as resilience, social connections, and practical support; and use of health care, social care, and wider societal resources will be collected before randomisation (baseline), immediately post-intervention, and 6 months later. Recruitment of participants, adherence to the programme, and the dose received will be assessed. Group sessions will be audio-recorded to evaluate the fidelity of delivery and participant engagement. Participants’ and facilitators’ feedback on the programme content and delivery, their experience, and the acceptability of the outcome measures and trial design will be collected through feedback forms, interviews, and focus groups.
.
. Discussion
. This trial will assess whether the programme delivery and evaluative trial design are feasible, to inform whether to progress to a definitive randomised controlled trial to test the effectiveness and cost-effectiveness of the Healthy Parent Carers programme.

Abstract:
Enhancing Social-Emotional Health and Wellbeing in the Early Years (E-SEE): a study protocol of a community-based randomised controlled trial with process and economic evaluations of the incredible years infant and toddler parenting programmes, delivered in a proportionate universal model.
INTRODUCTION: Behavioural and mental disorders have become a public health crisis and by 2020 may surpass physical illness as a major cause of disability. Early prevention is key. Two Incredible Years (IY) parent programmes that aim to enhance child well-being and development, IY Infant and IY Toddler, will be delivered and evaluated in a proportionate universal intervention model called Enhancing Social-Emotional Health and Wellbeing in the Early Years (E-SEE) Steps. The main research question is: Does E-SEE Steps enhance child social emotional well-being at 20 months when compared with services as usual? METHODS AND ANALYSIS: E-SEE Steps will be delivered in community settings by Early Years Children's Services and/or Public Health staff across local authorities. Parents of children aged 8 weeks or less, identified by health visitors, children's centre staff or self-referral, are eligible for participation in the trial. The randomisation allocation ratio is 5:1 (intervention to control). All intervention parents will receive an Incredible Years Infant book (universal level), and may be offered the Infant and/or Toddler group-based programme/s-based on parent depression scores on the Patient Health Questionnaire or child social emotional well-being scores on the Ages and Stages Questionnaire: Social Emotional, Second Edition (ASQ:SE-2). Control group parents will receive services as usual. A process and economic evaluation are included. The primary outcome for the study is social emotional well-being, assessed at 20 months, using the ASQ:SE-2. Intention-to-treat and per protocol analyses will be conducted. Clustering and hierarchical effects will be accounted for using linear mixed models. ETHICS AND DISSEMINATION: Ethical approvals have been obtained from the University of York Education Ethics Committee (ref: FC15/03, 10 August 2015) and UK NHS REC 5 (ref: 15/WA/0178, 22 May 2015. The current protocol is Version 9, 26 February 2018. The sponsor of the trial is the University of York. Dissemination of findings will be via peer-reviewed journals, conference presentations and public events. TRIAL REGISTRATION NUMBER: ISRCTN11079129; Pre-results.

Abstract:
Mindfulness-Based Cognitive Therapy for Young People and Their Carers: a Mixed-Method Feasibility Study
© 2017, the Author(s). We aimed to evaluate whether mindfulness-based cognitive therapy (MBCT) was feasible and acceptable for young people, their parents and the clinicians working with them; whether a parallel course for parents was a useful addition; and whether attendance at MBCT was associated with improved outcomes. The design was a mixed-method service evaluation of an eight-session MBCT programme for young people who were recovering from depression. The course was a manualised eight-session group intervention. Both young people (n = 18) and parents (n = 21) completed validated measures before and after the course. Semi-structured interviews were completed with some group participants and clinical staff working in the service. Care records were searched for additional contact following the intervention. Qualitative data from young people, parents and clinicians suggested that MBCT was acceptable and feasible and provided strategies to cope. The parent course was reported to provide personal support to parents and helped them cope with their child’s depression whilst also impacting the family, promoted shared understanding of depression and strategies to combat it and addressed intergenerational aspects of depression. Eighty-four per cent of participants attended at least 6/8 sessions, and 48% required no further intervention within the following year. Young people had statistically significant improvements across all outcome measures, whilst parents had statistically significant improvements in rumination, self-compassion and decentring.

Perfect Bedfellows: Why Early Intervention can Play a Critical Role in Protecting Children - a Response to Featherstone et al. (2014) - a Marriage Made in Hell: Child Protection Meets Early Intervention'
© 2017 the Author. In their article - a marriage made in hell: Child protection meets early intervention',Featherstone et al. (2014)question the value of early intervention in preventing or addressing early signs of child maltreatment. In this article, we summarise and critique their main contentions. Among the issues we cover are the difference between intervention and support, the tension between fidelity and flexibility, the relative value of randomised controlled trials, the evidence of - what works', the use of neuroscience, the place of innovation and the role of wider socio-economic factors. We are sympathetic to many of the points raised by Featherstone et al. but argue that they misrepresent early intervention, provide insufficient empirical support for their case and ignore evidence that runs counter to their views. We outline an alternative vision for child protection that addresses many of the concerns expressed while incorporating high-quality evidence on early intervention.

Debt counselling for depression in primary care: an adaptive randomised controlled pilot trial (DeCoDer study)
© Queen’s Printer and Controller of HMSO 2017. Background: Depression and debt are common in the UK. Debt Counselling for Depression in Primary Care: an adaptive randomised controlled pilot trial (DeCoDer) aimed to assess the clinical effectiveness and cost-effectiveness of the addition of a primary care debt counselling advice service to usual care for patients with depression and debt. However, the study was terminated early during the internal pilot trial phase because of recruitment delays. This report describes the rationale, methods and findings of the pilot study, and implications for future research. Objectives: the overarching aim of the internal pilot was to identify and resolve problems, thereby assessing the feasibility of the main trial. The specific objectives were to confirm methods for practice recruitment and the ability to recruit patients via the proposed approaches; to determine the acceptability of the study interventions and outcome measures; to assess contamination; to confirm the randomisation method for main trial and the level of participant attrition; and to check the robustness of data collection systems. Design: an adaptive, parallel, two-group multicentre randomised controlled pilot trial with a nested mixed-methods process and economic evaluation. Both individual- and cluster (general practice)-level were was used in the pilot phase to assign participants to intervention or control groups. Setting: General practices in England and Wales. Participants: Individuals were included who were aged ≥ 18 years, scored ≥ 14 on the Beck Depression Inventory II and self-identified as having debt worries. The main exclusion criteria were being actively suicidal or psychotic and/or severely depressed and unresponsive to treatment; having a severe addiction to alcohol/illicit drugs; being unable/unwilling to give written informed consent; currently participating in other research including follow-up phases; having received Citizens Advice Bureau (CAB) debt advice in the past year; and not wanting debt advice via a general practice. Interventions: the participants in the intervention group were given debt advice provided by the CAB and shared biopsychosocial assessment, in addition to treatment as usual (TAU) and two debt advice leaflets. The participants in the control group were given advice leaflets provided by the general practitioner and TAU only. Main outcome measures: (1) Outcomes of the pilot trial–the proportion of eligible patients who consented, the number of participants recruited compared with target, assessment of contamination, and assessment of patient satisfaction with intervention and outcome measures. (2) Participant outcomes–primary–Beck Depression Inventory II; secondary–psychological well-being, health and social care utilisation, service satisfaction, substance misuse, record of priority/non-priority debts, life events and difficulties, and explanatory measures. Outcomes were assessed at baseline (pre-randomisation) and at 4 months post randomisation. Other data sources–qualitative interviews were conducted with participants, clinicians and CAB advisors. Results: of the 238 expressions of interest screened, 61 participants (26%) were recruited and randomised (32 in the intervention group and 29 in the control group). All participants provided baseline outcomes and 52 provided the primary outcome at 4 months’ follow-up (14.7% dropout). Seventeen participants allocated to the intervention saw a CAB advisor. Descriptive statistics are reported for participants with complete outcomes at baseline and 4 months’ follow-up. Our qualitative findings suggest that the relationship between debt and depression is complex, and the impact of each on the other is compounded by other psychological, social and contextual influences. Conclusions: As a result of low recruitment, this trial was terminated at the internal pilot phase and was too small for inferential statistical analysis. We recommend ways to reduce this risk when conducting complex trials among vulnerable populations recruited in community settings. These cover trial design, the design and delivery of interventions, recruitment strategies and support for sites.

Effectiveness and micro-costing of the KiVa school-based bullying prevention programme in Wales: study protocol for a pragmatic definitive parallel group cluster randomised controlled trial.
BACKGROUND: Bullying refers to verbal, physical or psychological aggression repeated over time that is intended to cause harm or distress to the victims who are unable to defend themselves. It is a key public health priority owing to its widespread prevalence in schools and harmful short- and long-term effects on victims' well-being. There is a need to strengthen the evidence base by testing innovative approaches to preventing bullying. KiVa is a school-based bullying prevention programme with universal and indicated elements and an emphasis on changing bystander behaviour. It achieved promising results in a large trial in Finland, and now requires testing in other countries. This paper describes the protocol for a cluster randomised controlled trial (RCT) of KiVa in Wales. METHODS/DESIGN: the study uses a two-arm waitlist control pragmatic definitive parallel group cluster RCT design with an embedded process evaluation and calculation of unit cost. Participating schools will be randomised a using a 1:1 ratio to KiVa plus usual provision (intervention group) or usual provision only (control group). The trial has one primary outcome, child self-reported victimisation from bullying, dichotomised as 'victimised' (bullied at least twice a month in the last couple of months) versus 'not victimised'. Secondary outcomes are: bullying perpetration; aspects of child social and emotional well-being (including emotional problems, conduct, peer relations, prosocial behaviour); and school attendance. Follow-up is at 12 months post-baseline. Implementation fidelity is measured through teacher-completed lesson records and independent school-wide observation. A micro-costing analysis will determine the costs of implementing KiVa, including recurrent and non-recurrent unit costs. Factors related to the scalability of the programme will be examined in interviews with head teachers and focus groups with key stakeholders in the implementation of school-based bullying interventions. DISCUSSION: the results from this trial will provide evidence on whether the KiVa programme is transportable from Finland to Wales in terms of effectiveness and implementation. It will provide information about the costs of delivery and generate insights into factors related to the scalability of the programme.

Abstract:
Incredible Years parenting programme: Cost-effectiveness and implementation
© Emerald Group Publishing Limited. Purpose - There is growing interest in the economic evaluation of public health prevention initiatives and increasing government awareness of the societal costs of conduct disorder in early childhood. The purpose of this paper is to investigate the cost-effectiveness of the Incredible Years (IY) BASIC parenting programme compared with a six-month waiting list control. Design/methodology/approach - Cost-effectiveness analysis alongside a pragmatic randomised controlled trial of a group-parenting programme. The primary outcome measure was the Strengths and Difficulties Questionnaire (SDQ), a measure of child behaviour. Findings - the IY programme was found to have a high probability of being cost-effective, shifting an additional 23 per cent of children from above the clinical concern to below the cut-off on the SDQ compared to the control group, at a cost ranging from £1612-£2418 per child, depending on the number of children in the group. Originality/value - the positive findings of this study have led to ongoing implementation of the IY programme and is therefore an example of commitment to evidence-based service provision and investment in prevention initiatives.

Innovations in Practice: Further evidence on the effectiveness of the strengths and difficulties added value score as an outcome measure for child and adolescent services
© 2014 the Authors. Background: the Strengths and Difficulties Added Value Score (SDQ AVS) uses a large epidemiological study to predict follow-up parental SDQ scores for the evaluation of routine outcomes. Method: We tested the prediction of the SDQ AVS derived from a national population survey separately on scores for the waiting list control and intervention groups in a randomised controlled trial. If the SDQ AVS is to be clinically useful, it needs to function as expected across different populations. Results: in the control arm, the SDQ AVS predicted an effect size of 0.15 (95% CI -0.01-0.30) compared to an expected effect size of 0, as the children in this arm received no treatment. In the experimental arm, the SDQ AVS predicted an effect size of 0.62 (95% CI 0.42-0.83) compared to the study effect size of 0.53. Change scores overestimated the effect size in both arms (control 0.50 95% CI 0.34-0.66, intervention 0.85 95% CI 0.66-1.04). Conclusion: Our findings suggest that the SDQ AVS adjusts for spontaneous improvement, regression to the mean and attenuation.

Abstract:
Engaging parents in parenting programs: Lessons from research and practice
When evidence-based parenting programs are implemented in real-world settings they often fail to produce the results shown in efficacy trials. One reason for this is difficulties in engaging parents. This paper identifies lessons from a review of literature on engaging parents in parenting programs and presents a case study of the implementation of the Incredible Years BASIC program in the context of a randomized controlled trial. It examines the challenges encountered and efforts to overcome them. Key recommendations include: a clear recruitment process; good communication and liaison with stakeholders; incentives for recruitment and retention; active and creative outreach work; investment in building relationships with parents; making programs easily accessible; and having realistic expectations. © 2012 Elsevier Ltd.

Abstract:
Can study tours help promote evidence-based practice in children's services?
Interest in evidence-based programmes and the science underpinning them has mushroomed in the UK and Ireland in recent years as policy-makers and senior managers seek tried-and-tested methods of improving child well-being. This article examines whether study tours, a form of experiential learning, can help to promote evidence-based policy and practice in children's services. Participants on two study tours to the United States in 2005 to visit evidence-based programmes and their developers were interviewed by telephone 30-36 months later. Results are presented in terms of: (1) what participants felt they were exposed to on the study tours; (2) how the tours had changed their thinking; (3) what impact the tours had in terms of actions; (4) the factors that affected the impact of the study tours; and (5) the value added by the study tours over and above other means of learning about evidence and evidence-based services. © 2010 Taylor & Francis.

Abstract:
Linking prevention science and community engagement: a case study of the Ireland Disadvantaged Children and Youth Programme
Randomised controlled trials (RCTs) are acknowledged to provide the most reliable estimate of programme effectiveness, yet relatively few are undertaken in children's services. Consequently, there are few models with a demonstrated impact on child well-being, leading to a concern not only that services may frequently be ineffective but also that some may be harmful. This article considers how this state of affairs has come into being and discusses potential remedies for improving both the knowledge base and the quality of interventions. It focuses on ‘operating systems’ that link prevention science and community engagement and so help communities, agencies and local authorities to choose effective prevention, early intervention and treatment models. Specifically, it describes an attempt in Ireland to implement a robust programme of research into children's health and development, to rigorously design new services, evaluate their impact to the highest standard (using RCTs)and integrate the results into the policy process. Based on the authors' extensive first-hand experience of supporting the work, and the advice of international experts, the article reflects critically on the unforeseen challenges and offers lessons for others starting a similar enterprise. © 2008, Emerald Group Publishing Limited

Abstract:
Enhancing service evaluability: Lessons from a programme for disaffected young people
The effectiveness of children's services is often limited by a series of problems that also impede meaningful evaluation. This article describes and assesses research strategies to enhance the evaluability of a programme for disaffected young people, arguing that they have the potential to improve services more widely. It explores methods for developing a logic model, setting target group criteria, tightening programme components, identifying sufficient suitable candidates and selecting appropriate measures. Examples of other preparatory work aimed at helping the evaluation are given, including firming-up the programme and evaluation ethics and dealing with the politics of a fairly complex evaluation (a randomised controlled trial) that involves numerous stakeholders.

Abstract:
Exploring the potential of shadow controls in the evaluation of children's services
This article describes and presents a framework for an underused evaluation technique in the context of an evaluation of a programme for disaffected young people. Shadow controls - the use of expert judgement to estimate the success of a programme - are often dismissed in research design as an unreliable form of comparison, but can be useful in situations where there is limited scope for a control group or to enhance the causal inference attributable to nonexperimental evaluations. The exercise described uses a practice tool as a structure for making predictions about the situations of the young people on the programme, assuming they do not receive an intervention. These predictions (shadow controls) are then compared to outcome data for the young people at the end of the programme. The results of the exercise provide some important messages about the programmes effectiveness and the potential for strengthening nonexperimental evaluation methods. The article also discusses how the method can usefully inform evaluations of social programmes and encourage agency and user collaboration.
