ABSTRACT The psychometric properties of the Persian-language version of Obsessive-Compulsive Inventory- Revised (OCI-R) were studied in a sample of Iranian college students (N = 450). The total and each of the subscales of OCI-R-Persian demonstrated very high internal consistency as well as high test-retest reliability. Convergent and divergent validity of the OCI-R-Persian total scale and subscales were satisfactory. In general, the OCI-R-Persian appears to be a reliable and valid measure of obsessive-compulsive symptoms in this non-clinical sample of Iranian college students.
