Resumen:
Introduction. The Children Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) constitutes a very good instrument for the evaluation of obsesive-compulsive disorder (OCD) symptoms, by a clinical interview administered to the patient and parent, that includes the summary score of the clinician. Objective. We are proposing a Spanish version of the instrument, which is rated during a brief clinical interview to the parents and the patients. We are presenting data on reliability and validity using two out-patient samples. Methods. After the translation to Spanish, a back translation and adaptation to Spanish of the CY-BOCS, twenty eight out-patients (75% male) with a mean age of 12.1 (± 2.7) from two clinical settings on Mexico City were evaluated. Reliability was evaluated by computing the internal consistency (Cronbach's ?) on all interviews. To assess interrater agreement, the interviews were videotaped and scored by three independent raters and all of them included both the child and the parent interview. The CY-BOCS total scored was correlated with the K-SADS-PL diagnosis. Results. The CY-BOCS total score for all subjects was 16.5 ± 9.8. Cronbach's ? coefficient was 0.87; Pearson correlation of total CY-BOCS score with the K-SADS-PL diagnosis was 0.60 (p ? 0.05). The intraclass correlations coefficients for the parents, youngsters and clinician were 0.96, 0.94 and 0.92, respectively. Conclusions: The Spanish version of the CY-BOCS is a reliable and valid instrument, useful for both clinicians and researchers in child and adolescent OCD assessment.
