N2 - The objective of this study is to evaluate discriminative validity of the Young Mania Rating Scale (YMRS) and Children's Depression Rating Scale-Revised (CDRS-R) in a clinical sample of children when administered in an unfiltered manner (i.e., regardless of whether symptoms occur in a mood episode). The Kiddie Schedule for Affective Disorders and Schizophrenia is the gold standard for assessing psychiatric disorders in children and was used to make diagnoses in this study. Using a sample of 707 treatment-seeking youth (ages 6-12 years, M age = 9.7 years, 67.6% male), receiver operating curve analyses were performed and diagnostic likelihood ratios (DLRs) were calculated to evaluate the ability to change the odds and differentiate bipolar disorder from other disorders (using the YMRS) and depression from other disorders (using the CDRS-R). Using unfiltered administration, the YMRS achieved good discriminative validity when classifying bipolar disorder compared to other disorders (Area Under the Curve [AUC] = .86) and increased odds of a bipolar diagnosis given a score in the highest quintile (DLR = 6.12). Using unfiltered administration, the CDRS-R achieved moderate to good discriminative validity in classifying depressive disorders (DD) compared to other disorders (AUC BD in comparison = .78; AUC BD not in comparison = .84) and slightly increased odds of DD given a score in the highest quintile (DLR BD in comparison = 3.12; DLR BD not in comparison = 5.08). The YMRS and CDRS-R have moderate to good discriminative validity when administered in an unfiltered way in a sample of treatment seeking youth.
