Abstract
Factor structure and reliability of the Spanish adaptation of the Children's Yale-Brown ObsessiveCompulsive Scale - Self Report (CY-BOCS-SR). The aim of this study was the adaptation to Spanish of the "Children's Yale-Brown Obsessive-Compulsive Scale - Self Report" (CY-BOCS-SR), one of the most frequently utilized scales in the assessment of obsessive-compulsive behaviors. After its translation to Spanish, its factor invariance in boys and girls, reliability, and relationship with the children's age were examined. Lastly, normative data for this Spanish version are presented. The sample comprised 1,706 children and adolescents from the general population. Results show that the factor composition of the CY-BOCS-SR does not present a very good fit to the usual scoring of three scales were observed: Obsession Severity, Compulsion Severity, and total score. Results also show that the factor validity and reliability of the CY-BOCS-SR improve remarkably if items related to Resistance to Obsessions and Compulsions are considered a different factor from Severity. It is concluded that the Spanish version of the CY-BOCS-SR has similar psychometric characteristics as the original English version.
