Abstract
The Obsessive Beliefs Questionnaire (OBQ) is a self-report measure in development by the Obsessive Compulsive Cognitions Working Group (OCCWG), who studies cognitive aspects of obsessive–compulsive disorder (OCD). The aim of this paper was to evaluate the dimensionality of the OBQ in students (n = 995). Two models were tested in a confirmatory framework, corresponding to the OCCWG's (a) original six subscales (87 items), and (b) more recent three subscales (44 items). Both models fit the present data poorly; thus, an exploratory analysis was undertaken. Results revealed one large factor that is relevant, but not unique, to OCD, and three factors that are conceptually consistent with the OCCWG's recent three: (a) distorted beliefs about one's own thoughts, (b) perfectionism, and (c) inflated responsibility. Convergent and divergent validity analyses of the present OBQ factors generally supported the preceding interpretations. Readers are referred to the work of the OCCWG for revisions to the OBQ.
