Children's Yale-Brown Obsessive Compulsive Scale

The Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) is a 10-item clinician-administered semi-structured interview for assessing obsessive-compulsive symptoms in children and adolescents ages 6–17 years. Developed by Scahill, Riddle, and colleagues in 1997 as a child adaptation of the adult Y-BOCS, the CY-BOCS quantifies severity of obsessions and compulsions, insight, resistance, and functional impact. It is the gold-standard outcome measure in pediatric OCD research and clinical practice for diagnosis, severity rating, and treatment monitoring.
