The Obsessive-Compulsive Inventory-Revised (OCI-R) as a self-report questionnaire evaluates six obsessive-compulsive (OC) symptoms. The present study aimed to further evaluate the psychometric properties of a pre-existing Persian version of the OCI-R (i.e., six-factor structure, reliability and validity) and its adaptation to the DSM-5 recommendations in patients with obsessive-compulsive disorder (OCD). Three hundred and two individuals with OCD completed the OCI-R and other measures of OCD and general psychological distress. The results showed that the Persian version of the OCI-R replicated the six-factor model of the original OCI-R. Also, the five-factor structure of the scale with deleting the hoarding subscale's items had a better fit to the data than the original six-factor OCI-R. In addition, the Persian version of the OCI-R has been found to have good reliability (e.g., internal consistency and test-retest) and convergent and discriminant validity. The findings suggest that the Persian version of the OCI-R has a six-factor structure similar to the original scale. In addition, a five-factor structure by removing the hoarding subscale's items adapted to the DSM-5 is a valid scale in Iranian OCD patients.

强迫症量表修订版（OCI-R）作为自我报告调查表评估了六个强迫症（OC）症状。本研究旨在进一步评估已存在的波斯语版本的OCI-R（即六因素结构，信度和效度）及其对强迫症患者DSM-5建议的适应性（OCD）。320名强迫症患者完成了强迫症OCI-R和其他措施以及一般的心理困扰。结果表明，波斯文版的OCI-R复制了原始OCI-R的六因子模型。同样，与原始的六因素OCI-R相比，删除了sub积子量表项目的天平的五因素结构更适合数据。此外，已发现波斯版本的OCI-R具有良好的可靠性（例如，内部一致性和重新测试），并且具有收敛性和判别性。研究结果表明，波斯语版本的OCI-R具有类似于原始比例的六因子结构。此外，通过删除适合DSM-5的the积子量表的五因素结构在伊朗强迫症患者中是有效的量表。
