PSYCHOMETRIC PROPERTIES OF THE TURKISH ADAPTATION OF THE CHILDREN’S DEPRESSION RATING SCALE-REVISED IN TURKISH ADOLESCENTS ABSTRACT Objective: A reliable evaluation instrument is need to diagnose and measure the severity of childhood depression because there are several difficulties in determining its diagnosis. The Children’s Depression Rating Scale-Revised (CDRS-R) is an instrument that is evaluated by a physician and it needs bringing up the information from child/adolescent, parents and clinical assessment together. In the clinical population, CDRS-R provides general information about depressive symptomatology and also the severity of depression. The aim of this study was to translate and adapt the CDRS-R into Turkish and evaluate its psychometric properties in adolescents in the Turkish population. We determined the internal consistency, inter-rater reliability, construct validity, discriminant validity, and criterion validity of the CDRS-R Turkish version. Findings: Cronbach’s alfa (0.876) was found highly reliable. The interclass correlation coefficents ranged between 0.92 to 0.99 for each item, thus the inter-rater reliability was found statistically significant and highly correlated. Factor analysis was performed for constract validity; we identified 16 factors whose eigenvalues were greater than one. Varimax rotation was performed and four factors were evaluated. The CDRS-R’s item’s common variables were within the range of 0.45 to 0.87. The CDRS-R, CGI-S, and CGAS scores determined by the physician during the interview were compared with the CDRS-R raw score and they were found highly correlated. We found the Beck Depression Scale’s sensitivity was 90.9%, and specifity as 87.8%; the positive and negative predicitive values were 88% and 90%, respectively. The sensitivity, specifity, and positive and negative predictive values for CDRS-R were significantly high. Conclusion: We evaluated the CDRS-R’s psychometric properties in Turkish adolescents and performed it’s Turkish adaptation, and identified the preliminary findings of validity and reliability. We found that Turkish version of the CDRS-R has reliability and validity for use in the diagnosis and rating of severity of major depressive disorders in Turkish children and adolescents. |
