The conduct and oppositional defiant disorder scales (CODDS) for disruptive behaviour disorders.

This study evaluates the clinical validity of a five-minute instrument, the Conduct and Oppositional Defiant Disorder Scales (CODDS), for assessing oppositional defiant disorder (ODD) and conduct disorder (CD). Children (N = 428) aged 11-12 years and their caregiver were administered the NIMH DISC-IV (Diagnostic Interview Schedule for Children), the CODDS, and validity measures. A second sample (N = 671) was utilized to develop a brief measure of limited prosocial emotions based on DSM 5. Receiver operating characteristic (ROC) curves documented good sensitivity and specificity for CODDS scales in predicting DISC-IV clinical diagnoses of ODD (85%, 72% respectively) and CD (85%, 88%) diagnoses. Baseline CODDS provided added value over and above baseline clinical DISC- diagnoses in predicting future DISC ODD and CD diagnoses 12 months later, as well as in predicting social and school functioning. Study 2 further established psychometric properties of the CODDS, with brief measures of CODDS limited prosocial emotions (LPE) having a good fit to the hypothesized DSM 5 four-factor structure of LPE. Findings indicates that the CODDS has utility as a five-minute proxy for diagnoses of ODD and CD in clinical research and potentially practice where time and resources are limited.
