Abstract

Introduction: The Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) is a widely used clinician-administered instrument developed to overcome the problems with the available instruments for OCD in children. The aim of this study was to assess the psychometric properties of the CY-BOCS in an Iranian sample. Methods: The psychometric properties of the CY-BOCS were assessed in clinical samples with obsessive-compulsive disorder (OCD, n=70), with anxiety disorders (n=58) and a non-clinical student sample (n=400). Using the Structured Clinical Interview for DSM-5 Axis I Disorders (SICD-5) by a trained psychiatrist, all participants were administered the CY-BOCS; Obsessive Compulsive Inventory-Child Version (OCI-CV); Children's Depression Inventory (CDI); and Multidimensional Anxiety Scale for Children (MASC). Receiver Operating Characteristic (ROC) curves were used to determine the optimal threshold scores for CY-BOCS. Results: The confirmatory factor analysis demonstrated that the original two-factor structure was valid in the Iranian sample. The overall and individual subscale scores showed moderate to good internal consistency and convergent validity as well as test-retest reliability. ROC analysis showed the area under the curve to be approximately 92. For OCD diagnosis in �any anxiety disorder� group, the CY-BOCS demonstrated the best psychometric properties for a cut-off score to be 17, with a sensitivity of 98.5, specificity of approximately 76, and positive predictive value (PPV) of about 12. Conclusion: The Persian version of the CY-BOCS is a valid psychometric indicator for obsessive compulsive disorders with adequate sensitivity and specificity, and high NPV and PPV with an optimum cut-off score of 17 for OCD diagnosis. © 2019 Elsevier Inc.
