Behavioural activation for overweight and obese adolescents with low mood delivered in a community setting: feasibility study

BACKGROUND: Mood and weight problems are common in young people, yet few treatments address both conditions concurrently. Behavioural activation (BA) has shown promise as a treatment for adults with comorbid obesity and depression. This study aimed to examine the feasibility and acceptability of a manualised BA treatment targeting weight and mood problems in young people. METHODS: Young people with low mood and weight difficulties were identified via a school-based screening process. Following a diagnostic interview, young people with clinically significant mood problems and concurrent overweight/obesity were invited to participate. A total of 8–12 sessions of BA were delivered by a graduate therapist to eight adolescents (four male) aged 12–15 years. Weight, mood and functioning were assessed before, during and after treatment, and a semistructured qualitative interview was conducted, along with selected outcome measures at 4 months’ follow-up. RESULTS: Low attrition and positive qualitative feedback suggested the intervention was acceptable. Trends towards a reduction in reported depression symptoms and improved functioning scores were observed at follow-up, with more mixed results for change in body mass index. Of those attending the 4-month follow-up, 57% (4/7) no longer met the screening threshold for major depressive disorder. However, low screening and baseline recruitment rates would pose challenges to executing a larger trial. CONCLUSIONS: BA delivered by a graduate therapist in a British community setting is an acceptable, feasible treatment for comorbid mood and weight problems in adolescence, and its effectiveness should be evaluated in an adequately powered randomised controlled trial.
