Abstract

Abstract: We evaluated the construct validity of the Child Yale–Brofwn Obsessive–Compulsive Scale (CYBOCS) in a large clinical sample ( N =730) using confirmatory factor analysis. Results found inadequate fit for a priori models, though a model accounting for overlapping item content displayed good fit. Parallel obsessions/compulsions items may provide largely redundant information on the CYBOCS. Findings suggest modifying the CYBOCS to reduce burden on researchers, patients, and clinicians, and to more accurately measure pediatric obsessive–compulsive disorder (OCD). Highlights: We examined contemporary models of pediatric obsessive–compulsive disorder (OCD). Through confirmatory factor analysis, we found that prior models did not fit well. We identified poor model fit likely to be a result of redundancy in item content. Merging redundant item content could reduce OCD assessment burden by more than half.
