Longitudinal invariance of the Children's Depression Rating Scale-Revised in adolescents.

ABSTRACT: The Children's Depression Rating Scale-Revised (CDRS-R) is a widely used interview measure of adolescent major depression (major depressive disorder), with sum scores and their changes over time interpreted as changes in one underlying construct. This interpretation assumes that the CDRS-R measures a single construct of depression (unidimensionality) in the same way across time (longitudinal invariance)-assumptions that have yet to be established but were tested in this study. Adolescents (N = 197; ages 13-18 years old) with lifetime major depressive disorder, as well as healthy controls, completed the CDRS-R and a self-reported depression symptom measure, the Inventory of Depression and Anxiety Symptoms (IDAS), at baseline and 6 months follow-up.
