Dr Lloyd’s research interests centre on the development and evaluation of complex interventions for behaviour change in relation to promoting children’s health. For the last 6 years, she has been leading the development and evaluation of a novel school-located obesity prevention intervention called the Healthy Lifestyles Programme (HeLP). It has followed the MRC framework for the development and evaluation of complex interventions and has gone through three stages of piloting involving six primary schools (c400 children and their families) in Exeter. 'HeLP' seeks to deliver healthy lifestyle messages using assessible and engaging delivery methods to encourage children to seek their parents support to effect change within the family. Key to engaging the children are the interactive drama activities which have been developed in collaboration with Headbangers Theatre Company. Results to date show that the Programme is acceptable and feasible to schools, children and their families and that the study design is feasible for a definitive trial. 'Proof of concept' has also been established as results from the exploratory trial showed positive changes in favour of the intervention across all targeted behaviours (snacking, screen time and physical activity) which appeared to have a sustained effect on children's weight status and body shape. Based on these pilot studies 1.4 million pounds of funding was secured from NIHR to run the definitive evaluation of ‘HeLP’ which she is now managing. The trial involves 32 schools across Devon and Plymouth and results will be available in 2016.

Research

Research interests

Understanding context is key to developing an intervention that is feasible and acceptable to the target group and having spent the past 6 years developing a complex behavioural intervention to prevent obesity in school children has led Dr Lloyd to focus on the science of complex adaptive systems in order to understand the wider ramifications of intervening and the interactions that occur not only between components of the intervention but between the intervention and the context in which it is being delivered. Interventions impact on evolving networks of person-time-place interaction, changing relationships, displacing existing activities and redistributing and transforming resources and this has implications for how interventions should be evaluated and how they could be made more effective. The Healthy Lifestyles Programme utilises a range of behaviour change techniques, however it is the dynamic interaction between these techniques, their mode of delivery, the skills and competencies of the deliverer as well as the characteristics of the participants that render them effective or not in any particular context. She is particularly interested in how context and mechanism (make up, behaviour and interrelationships of the processes) work together to deliver the outcome.
