Systematic reviews of behaviour change interventions: using BCT taxonomies for evidence synthesis

Abstract

Rationale: Increasing numbers of published behaviour change interventions has created a growing body of evidence to support behaviour change. To inform future interventions and support the translation of research into practice, evidence synthesis through systematic reviews is crucial. Until recently, systematic reviews of behaviour change interventions were limited by the lack of shared language to describe content, specifically the techniques that lead to behaviour change. However, over the last few years, a number of standardised taxonomies of behaviour change techniques (BCTs) have been published. This year’s EHPS conference, ‘Behaviour-change: Making an impact on health and health services’ is a well-timed opportunity to discuss examples of evidence synthesis using BCT taxonomies and to reflect on challenges and future developments in this area. Aims: - To showcase systematic reviews of behaviour change interventions across behaviours and populations - To describe the use of BCT taxonomies in synthesising evidence - To outline possible limitations and challenges of using BCT taxonomies - To consider future developments in the synthesis of behaviour change interventions. Summary : The symposium will consist of five oral presentations reporting systematic reviews that have used BCT taxonomies to describe the content of behaviour change interventions Milou Fredrix will present on the effectiveness of goal setting interventions to improve health outcomes in diabetes. Mei Yee Tang’s presentation will focus on self-efficacy in the initiation of physical activity in clinical Samples. Marta Marques will discuss behavioural digital interventions for weight loss and maintenance. Ellinor Olander will describe the effectiveness of physical activity interventions in pregnancy. Finally, Fabiana Lorencatto will discuss using a BCT taxonomy to code sedentary behaviour reduction interventions. The discussion will provide an opportunity to reflect on the advantages and challenges of using BCT taxonomies for evidence synthesis and to consider future developments in the synthesis of behaviour change interventions.
