Designing, factor structure, validity, and reliability of the New Partner-Related Obsessive-Compulsive Symptoms Inventory (New PROCSI): A questionnaire based on Iranian culture

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.

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.

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.

It seems that the original and new PROCSI are different and require further research.
