title: Psychometric properties of the Persian language version of Obsessive Beliefs Questionnaire (OBQ-44) in Iranian general population.
abstract: The Obsessive Beliefs Questionnaire-44 (OBQ-44), a self-report measure, was developed by the Obsessive Compulsive Cognitions Working Group (OCCWG) to assess beliefs considered relevant in the etiology and maintenance of obsessions and compulsions. The purpose of this study was to evaluate the psychometric properties of the Persian language version of the Obsessive Beliefs Questionnaire (POBQ-44). A sample of 222 medical students from an Iranian university was used to assess the reliability and validity of the POBQ-44. The results indicated five factors: 1) general, 2) perfectionism, certainty, 3) responsibility and threat estimation, 4) importance and control of thoughts, 5) complete performance. Each of these factors was found to have adequate test-retest and internal consistency reliability. Each of the factors was associated with O-C symptoms. In addition, adequate convergent validity was found with a measure of obsessive compulsive symptoms, and discriminate validity was found with measures of depression and anxiety.
