Integrating COM-B and the Person-Based Approach to develop an ACT based therapy programme to raise self-determination in adolescents with obesity

Abstract

This paper details the development of the Adolescent Intrinsic Motivation AIM2Change intervention to support weight-management in young people previously unable to make changes whilst attending a tier 3 weight management service for children and young people. AIM2Change is an acceptance and commitment therapy (ACT) based intervention that will be delivered one-to-one online over a seven-week period. To develop this intervention, we have triangulated results from a qualitative research study, patient and public involvement groups (PPI) and a COM-B (capability, opportunity, motivation, behaviour) analysis, in a method informed by the person-based approach. The integrated development approach yielded a broad range of perspectives and facilitated the creation of a tailored intervention to meet the needs of the patient group whist remaining pragmatic and deliverable. The next steps for this intervention will be in-depth co-development of the therapy sessions with service users, before implementing a feasibility randomised control trial.
