The clinical assessment of obsessive-compulsive symptoms in children and adolescents - A study with the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS-D) Abstract. Objective: The CY-BOCS is internationally the most widely used instrument for the assessment of juvenile obsessive-compulsive disorder (OCD). In this study, for the first time, the psychometric properties of a German version of the CY-BOCS (CY-BOCS-D) are examined in a pediatric OCD sample (n = 169; age 11-18 years). Method: The factor structure, internal consistencies, convergent and divergent validity are analyzed. Results: The exploratory factor analyses confirm a two-factor structure of the CY-BOCS-D Rating Scale and reveal a four-factor structure of the CY-BOCS-D Checklist. The internal consistencies are satisfactory to very good, convergent and divergent validity are confirmed. Conclusions: The results support the CY-BOCS as a "gold standard" also for OCD-diagnostics in German-speaking countries.
