Background:
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 based intervention that will be delivered one-to-one online over a seven-week period.
Methods:
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.
Results:
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.
Conclusions:
The next steps for this intervention will be in-depth co-development of the therapy sessions with service users, before implementing a proof of concept trial.
