Developing theory and evidence based intervention content using the Behaviour Change Wheel, Theoretical Domains Framework, and the Person-Based Approach: A worked example for an intervention targeting sedentary behaviour with people living with obesi

A theory, evidence and person-based approach to develop an intervention to reduce sedentary behaviour in the domestic domain for people living with obesity is described. The BCW guide, COM-B model, TDF and BCT-Taxonomy provided the framework for selection of theoretical content. To ensure relevance for the target population, the content and mode of delivery was developed in collaboration with people with moderate to severe obesity using the PBA.
