Objectives : The current study aimed at a preliminary investigation of validity and reliability of Bell Object Relations and Reality Testing Inventory (BORRTI). Method: A total of 141 (88 females and 53 males) students from Honar University (Tehran, Iran) were selected based on a convenience sampling method and assessed by BORRTI and the Symptom Checklist-90-Revised (SCL-90-R) questionnaires. Data was analyzed by Pearson correlation method. Results: There were significant correlation among all subscales of BORRTI and all components of SCL-90-R (p≤0.001). The BORRTI reliability by test-retest within 21 weeks interval was from 0.78 for delusion and hallucination subscale to 0.65 for uncertain perception. Besides, alpha Cronbach for subscales was from 0.66 for social incompetency to 0.82 for alienation. Conclusion: The Persian version of BORRTI was suitably valid and reliable in assessing two constructs of object relations and reality testing.
