Design outcomes

Primary

MeasureTime frame
The dimensional severity of depression, measured through both self-report and observer-report assessments. The Observer and Self-Assessment Scales for Depression (FBB-DES and SBB-DES) from the DISYPS-III will be used for evaluations by both parents and adolescents at t0 (pre-intervention), t1 (post-intervention IG), t2 (post-intervention CG) and t3 (follow-up 12 months after t1).

Secondary

MeasureTime frame
1. Categorical depression diagnosis will be measured with ILF-INTERNAL from DISYPS-III at t0 and t1 2. Health-related quality of life in adolescents will be assessed using the KIDSCREEN-10 through both self-report and observer-report (parents) at t0, t1, t2, and t3 3. Adolescent self-efficacy will be measured using the General Self-Efficacy Scale (SWE) by Jerusalem and Schwarzer through self-report at t0, t1, t2, and t3 4. Suicidal behaviour and thoughts will be assessed using the DISYPS interview and DISYPS self- (DISYPS-SBB) and observer-report questionnaire (DISYPS-FBB) through self-report at t0, t1, t2, and t3 5. Other psychological issues and comorbid symptoms will be assessed through observer-report by parents using the Strength and Difficulties Questionnaire (SQD-Deu) at t0, t1, t2, and t3 6. The cost-effectiveness analysis from a health economic perspective is performed using EQ-5D-Y in the adolescents' self-report and the resource utilization of the FIM-K, which is completed by the parents in the observer-report at t0, t1, t2, and t3
