Is cognitive behavioural therapy an effective complement to antidepressants in adolescents? A meta-analysis.

Objective: Evidence on effectiveness of combined treatments versus antidepressants alone in adolescents consists on a few studies in both major depressive and anxiety disorders. A meta-analysis of randomised 12-week follow-up studies in which antidepressant treatment was compared to combined treatment consisting of the same antidepressant with cognitive behavioural therapy has been performed. Methods: Data were entered into the Cochrane Collaboration Review Manager software and were analysed within a random effect framework. A quality assessment has been performed through Jadad Scale. Results: Higher global functioning at the Children's Global Assessment Scale was found in the combined treatment group (p < 0.0001) as well as higher improvement at the Clinical Global Impressions Improvement Scale (p = 0.04). No benefit of combined treatment was found on depressive symptomatology at the Children's Depression Rating Scale – Revised. Conclusion: Combined treatment seems to be more effective than antidepressant alone on global functioning and general improvement in adolescents with major depressive and anxiety disorders.
