Using the behavior change wheel to design a novel home-based exercise program for adults living with overweight and obesity: Comprehensive reporting of intervention development.

Abstract

Physical activity and exercise are movement behaviors that support the lifestyle management of overweight and obesity. However, home-based exercise programs are commonly generic, and inconsistently undertake a holistic approach to program design. This work applied the Behavior Change Wheel, supplemented with previously conducted interviews, to the development of a home-based exercise program, specifically for people living with overweight and obesity. This provided an understanding of the target behavior and identified a behavioral diagnosis. These findings were mapped onto the Capability, Opportunity, Motivation-Behavior model and Theoretical Domains Framework, identifying changes needed and corresponding intervention functions. Suitable Behavior Change Techniques were identified, alongside Capability Opportunity Motivation-Behavior components needed to facilitate an increase in exercise behaviors, and five key intervention functions. This housed the delivery of 24 Behavior Change Techniques, including goal setting, feedback, monitoring and repetition. Applying the Behavior Change Wheel has enabled detailed development of a home-based exercise program for adults living with overweight and obesity.
