Feasibility, Acceptability and Effect of a Transdiagnostic Psychological Treatment for Anxiety and Depression in Youth.

A transdiagnostic psychological group treatment, Unified Protocol (UP-C/A), one intervention, is tested for children and youth with anxiety disorders and/or depression seeking help in routine care in two primary care locations. Parents are at the same time offered parent training in a group format coupled with the module the children are working on. Feasibility, acceptability and effect of the intervention will be studied, with child self-report, parent-report and therapist assessment.
