Abstract The factor structure of the Yale‐Brown Obsessive‐Compulsive Scale (Y‐BOCS) has been examined in a number of prior investigations; however, findings have not consistently yielded a stable factor solution. The present study therefore tested the fit of each previously reported factor structure. One hundred thirty‐one adults with obsessive‐compulsive disorder (OCD) were administered the Y‐BOCS; a portion of these participants completed self‐report measures of depression and obsessive‐compulsive symptoms and were rated on a global impairment index. Consistent with the originally proposed structure, confirmatory factor analyses supported a factor structure comprised of obsession and compulsion factors. Reliability and convergent validity of these factors were generally satisfactory, although divergent validity was not entirely supported. Implications of these findings on scoring the Y‐BOCS are discussed. Depression and Anxiety 22:28–35, 2005 . © 2005 Wiley‐Liss, Inc.
