"If there is a tension about something, I can solve it": A qualitative investigation of change processes in a trial of brief problem-solving interventions for common adolescent mental health problems in India.

We infer from our qualitative analysis that changes in problem-solving style and problem orientation underpinned long-term symptomatic and functional improvements. Participants in the counsellor-led intervention appeared better able to sustain the use of problem-solving skills and generalize this approach beyond the original presenting problems. We attribute the differences between arms to the influence of direct advice and supportive interactions with counsellors. Practice implications are discussed.
