Children's Depression Rating Scale-Revised (CDRS-R): development of a German version and psychometric properties in a clinical sample

The Children's Depression Rating Scale - Revised (CDRS-R) is a semistructured, clinician-rated interview for the assessment of depression in children and adolescents. While the CDRS-R is frequently used in clinical studies to evaluate the treatment of juvenile depression, no validated German version is yet available. The CDRS-R was translated into German and tested on 60 inpatients (26 female, 34 male) between 7.5 to 17.9 years (mean = 13.8, standard deviation = 2.9) who were interviewed within the first week of treatment. K-SADS-PL and BDI-II resp. DIKJ were additionally used for validation. The German version of the CDRS-R shows a high internal consistency (α = 0.90), and the item-total correlations are good. Correlations between CDRS-R and self-report questionnaires (DIKJ and BDI-II) are high. The mean CDRS-R score of patients with major depressive disorder is similar to the prior results of international studies. The German translation of CDRS-R shows good psychometric properties. Its application may be helpful in diagnosing and monitoring depressive disorders in children and adolescents.
