Cognitive-behavioral therapy (CBT) has been documented to be effective in treating depression in adolescence, but there is great variability in the clinical outcome of CBT trials. This may in part be due to variations in the content of, and emphasis on different CBT components. Moreover, little is known about adolescents' subjective experiences of CBT interventions, which also might be related to outcome. In this qualitative study, nine adolescents were interviewed about their experiences of the specific components in a CBT group intervention. The results showed that the adolescents experienced the cognitive component of the course as most useful, but somewhat difficult to use. Psycho-education, behavioral activation and the social relationships component were also experienced as beneficial. Their experiences regarding the relaxation training and the homework assignments were mixed. Negative aspects of the intervention included the experience of guilt related to being depressed.
