Receiver Operating Characteristic Curve Analysis of Screening Tools for Bipolar Disorder Comorbid With ADHD in Schoolchildren.

We compared Child Behavior Checklist (CBCL)-AAA (Attention Problems, Aggressive Behavior, and Anxious/Depressed) and Parent-Young Mania Rating Scale (P-YMRS) profiles in Brazilian children with ADHD, pediatric-onset bipolar disorder (PBD), and PBD + ADHD. Following analyses of variance or Kruskal-Wallis tests with multiple-comparison Least Significant Difference (LSD) or Dunn's Tests, thresholds were determined by Mann-Whitney Tests and receiver operating characteristic (ROC) plots. Relative to ADHD, PBD and PBD + ADHD groups scored higher on the Anxious/Depressed, Thought Problems, Rule-Breaking, and Aggressive Behavior subscales and Conduct/Delinquency Diagnostic Scale of the CBCL; all three had similar attention problems.
