Objective: To develop and examine the psychometric properties of the Children's Yale-Brown Obsessive-Compulsive Scale Second Edition (CY-BOCS-II) in children and adolescents with obsessive-compulsive disorder (OCD). Method: Youth with OCD (N = 102; age range 7–17 years), who were seeking treatment from 1 of 2 specialty OCD treatment centers, participated in the study. The CY-BOCS-II was administered at an initial assessment, and measures of OCD symptom severity, anxiety and depressive symptoms, behavioral and emotional problems, and global functioning were administered. Inter-rater and test-retest reliabilities were assessed on a subsample of participants (n = 50 and n = 31, respectively) approximately 1 week after intial assessment. Results: The CY-BOCS-II demonstrated moderate-to-strong internal consistency (α = 0.75–0.88) and excellent inter-rater (intraclass correlation coefficient = 0.86–0.92) and test-retest (intraclass correlation coefficient = 0.95–0.98) reliabilities across all scales. Construct validity was supported by strong correlations with clinician-rated measures of OCD symptom severity and moderate correlations with measures of anxiety symptoms. Exploratory factor analysis showed a 2-factor structure, which was generally inconsistent with its adult counterpart, the Yale-Brown Obsessive-Compulsive Scale Second Edition. Conclusion: Initial findings support the CY-BOCS-II as a reliable and valid measure of obsessive-compulsive symptoms in youth.
