YALE-BROWN OBSESSIVE-COMPULSIVE SCALE AND US-NATIONAL-INSTITUTE-OF-MENTAL-HEALTH GLOBAL OBSESSIVE-COMPULSIVE SCALE IN TURKISH - RELIABILITYAND VALIDITY

Fifteen patients with DSM-III-R diagnosis of obsessive-compulsive diso rder (OCD) were rated according to the Turkish version of the Yale Bro wn Obsessive Compulsive Scale (Y-BOCS) and the US National Institute o f Mental Health Global Obsessive Compulsive Scale (NIMH-GOCS) by 7 rat ers independently from audiotaped interviews. Patients also completed the Maudsley Obsessive Compulsive Inventory (MOCI). Interrater reliabi lity of Y-BOCS and NIMH-GOCS were very good as well as correlations be tween these two scares. The correlations of MOCI with Y-BOCS and NIMH- GOCS were not significant. We found Y-BOCS and NIMH-GOCS to be reliabl e and valid instruments in assessing the severity of OCD. These findin gs suggest that MOCI may not be a suitable instrument for assessing th e severity of OCD.
