Feasibility study of a new behavioural activation programme for young people with depressed mood.

Background: Behavioural activation (BA) is effective in adults with depression but the evidence for young people (YP) is less clear. We therefore developed and tested a new coproduced BA programme.

Method: In phase one (2014 to 2015 inclusive), we codeveloped with young people attending specialist child and adolescent mental health service (CAMHS) an 8-session BA workbook.
