Validation of the Persian Version of the Obsessive-Compulsive Inventory-Revised in a Student Sample

The Obsessive-Compulsive Inventory-Revised (OCI-R) has been developed to evaluate the severity of obsessive-compulsive symptoms in both clinical and non-clinical individuals. The present study investigated the psychometric properties of a Persian version of this scale. The OCI-R Persian version was completed by 400 graduate students from the University of Tehran and Tehran University of Medical Sciences. Results revealed satisfactory internal consistency as measured by Cronbach’s alpha coefficient (ranging from 0.50 to 0.72). In addition, the six-factor structure found by the original study was confirmed in the present study by a confirmatory factor analysis. In brief, the Persian version of the OCI-R seems satisfactory for measuring obsessive-compulsive disorder symptoms in non-clinical samples. However, future research is needed to confirm these data in a sample of OCD patients.
