Objective: The purpose of the present study was to evaluate the factor structure, validity, and reliability of the revised Relationship Obsessive-Compulsive Inventory (ROCI), with emphasis on Iranian culture.
Method: The statistical sample consisted of 341 married students studying in Tehran universities in the academic year 2018-2019, who were selected by available sampling method. The New ROCI, Obsessive-Compulsive Inventory-Revised (OCI-R), Obsessive Beliefs Questionnaire (OBQ), Depression, Anxiety and Stress Scale (DASS), Dyadic Adjustment Scale (DAS), and Relationship beliefs inventory (RBI) were the tools of the present study.
Results: The Content Validity Index (CVI) and Content Validity Ratio (CVR) of the new ROCI were good. Also, there was a significant and negative correlation between all subscales and the total score of the new ROCI with all subscales and the total score of the DAS, and there was also a significant positive correlation between the subscales and the total score of the new ROCI with the subscales and the total score of OBQ, OCI-R, RBI, and DASS. Also, the two factor model explained 54.50% of the variance in the new ROCI. Furthermore, all of the confirmatory factor analysis indices of the new ROCI were better than the original ROCI. The results of test-retest correlation of the factor one and two of ROCI were 0.85 and 0.78, respectively. Also, the Cronbach's alpha of the factor one and two of ROCI were 0.60 and 0.74, respectively.
Conclusion: In general, it can be said that the new ROCI was different from the original ROCI, and the new ROCI had better indicators than the original ROCI.
