Background: Research has shown that there are relationships between early maladaptive schemas (EMSs) and obsessive-compulsive symptoms (OC), but no research has been performed on the mediating role of  inferential confusion in this regard. Therefore,  the question of research is whether  inferential confusion can mediate this relationship?. Aims: The present study was carried out aming to investigate the mediation role of inferential confusion in the relationships between EMSs and OC symptoms in university students. Method: The present research was a descriptive-correlational study. The statistical population of this study included all undergraduate students  in  Arak University. Among them, a  sample  of 532  undergraduate students were selected by multiple cluster sampling method. To collect data, the obsessive-compulsive inventory-revised (Foa et al. 2002), the Young early maladaptive schema questionnaire-short form (1998), and the inferential confusion questionnaire-expanded version (Ardema et al, 2010) were used. Results: According to maladaptive schemas and inferential confusion theories, findings indicated the significant direct and indirect effects of EMSs on OC symptoms through the mediating inferential confusion (p<0/01, p<0/05) .Conclusions: The findings emphasizd that both EMSs and inferential confusion are important to explain OC symptoms. Also,  inferential confusion as a mediator is a variable that explins the relationships between EMSs and OC symptoms. 

Background: Research has shown that maladaptive emotional schema (MES) leads to anxiety, depression, obsessive-compulsive, interpersonal damage, and mood disorders. Since, MES may be influenced by cultural differences, In the present research, the psychometric properties of the Persian version of emotional schemas in Iranian culture will be investigated.
Aims: The present study was conducted with the aim of investigating the psychometric properties of the short-form emotional schema questionnaire in Iranian students.
Methods: The current research was of a descriptive-correlation type. The statistical population of the study includes all students in Tehran City in 2021, out of which 306 students were selected based on Cochran's formula using convenience random sampling method, and the participants completed emotional schema-short form (Leahy, 2012) and Cognitive emotion regulation (Garnefski and Kraaij, 2006) questionnaires. Data were analyzed by Cronbach's Alpha, content validity index (CVI), content validity ratio (CVR), and confirmatory factor analysis.
Results: Cronbach’s Alpha was obtained above 69% for all scales. CVR and CVI were calculated above 80%, which suggests the acceptable content validity of the scale. Confirmatory factor analysis confirmed the 8-factor structure of the emotional schema scale. This, it was shown that the model enjoys a suitable goodness of fit in the sample of Iranian students.
Conclusion: Considering the appropriate psychometric properties of the Persian version of the Emotional Schema Scale, it can be suggested to the specialists in the field of psychology and consultants to use this scale in research and diagnostic settings.
