Factor Structure of the Yale-Brown Obsessive Compulsive Scale.

The dimensions underlying the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) (W. Goodman and others, 1989) were examined by performing a confirmatory factor analysis of the scale using responses from 404 patients. Results support a two-factor model of obsessive-compulsive symptoms, reflecting degree of disturbance and severity of symptoms. (SLD)
