Abstract

Introduction: The present study aimed to investigate the factor structure, validity and reliability of the revised Partner-Related Obsessive-Compulsive Symptoms Inventory (New PROCSI) with respect to Iranian culture.
 
Materials and Methods: The statistical sample consisted of 341 married students studying in Tehran universities in the academic year 2019-2020 that were selected by the convenient sampling method. The New PROCSI, 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 PROCSI were good. Also, there was a significant and negative correlation between all subscales and the total score of the new PROCSI with all subscales and the total score of the DAS, and there was also a significant and positive correlation between the subscales and the total score of the new PROCSI with the subscales and the total score of OBQ, OCI-R, RBI, and DASS. Furthermore, the one-factor model explained 28.41% of the variance in the new PROCSI, and the Chi-Square/df index of the new PROCSI was better than the Chi-Square/df index of the original scale. On the other hand, the CFI and RMSEA of the original scale were better than the new PROCSI. The results of the test-retest correlation and the Cronbach's alpha of the new PROCSI were 0.86 and 0.91, respectively.
 
Conclusion: It seems that the original and new PROCSI are different and require further research.
