Cognitive behavior models for Obsessive-Compulsive Disorder (OCD) are based currently on the presence of specific beliefs associated with the disorder. Among these beliefs are inflated responsibility, concerns over thought-action fusion, and overimportance of thoughts. the aim of this study was to compare scores from the subscales of the Obsessive Beliefs Questionnaire (OBQ-87), developed by the Obsessive-Compulsive Cognitions Working Group (OCCWG, 2001), in 24 patients from an OCD clinic (OCD) and 24 patients from a Medical Clinic (MC) for ambulatory and chronic diseases. All OCD patients were diagnosed using the SCID, and the OCD portion of the SCID was used to rule out patients with OCD from the MC group. the Yale-Brown Obsessive-Compulsive Scale (YBOCS) and Dysfunctional Attitudes Scale (DAS) were also administered. the results indicated that, contrary to predictions, in the domains of Tolerance for Uncertainty, Threat estimation, Responsibility and Perfectionism, the MC group presented higher scores than the OCD group. the same findings occurred with DAS, which was significantly correlated with the OBQ. Possible explanations for these findings are discussed, as well as suggestions for future research with both groups. (C) 2010 Elsevier B.V. All rights reserved.
