title: Symptom correspondence between clinicians and patients on the Yale-Brown Obsessive Compulsive Scale.
abstract: The present study examined concordance between the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and its self-report version (Y-BOCS-SR), as well as theoretically derived moderators. Sixty-seven adults (ages 18-67) with obsessive-compulsive disorder (OCD) were administered the Y-BOCS prior to completing self-report measures. The Y-BOCS-SR generated lower scores relative to the clinician-administered Y-BOCS (5.3 points lower). Strong correspondence was shown between the Y-BOCS and Y-BOCS-SR; however, many items exhibited fair to moderate agreement, particularly the resistance and control against obsessions/compulsions items. Depression significantly moderated correspondence such that Y-BOCS-SR scores significantly predicted Y-BOCS scores in the presence of low and average depression levels in our sample, but not for patients with high levels of depression relative to the rest of our sample; gender, generalized anxiety and obsessionality did not significantly impact agreement. Synthesizing the present data, the Y-BOCS-SR demonstrates modest agreement with the Y-BOCS and may underestimate clinical severity especially for those with high levels of depression.
