Methods: This study was cross-sectional research conducted by a correlation method. The statistical population included all staff of Khayyam University in the academic year of 2018-2019 and the sample size was 200 students selected by a proportional stratified sampling method. The questionnaires used in this study included Obsessive-Compulsive Inventory-Revised (OCI-R), Young Early Maladaptive Schema Questionnaire-short form (75 questions) and Intolerance of Uncertainty Scale (IUS). To analyze the data, the structural equation method and Amos-22 software were used. Results: The results showed that mediating model of intolerance of uncertainty in the relationship between the early maladaptive schemas and symptoms of obsessive-compulsive disorder in the University staff has a good fit. Conclusion: All pairwise relationships of variables were significant, meaning that there was a positive and significant relationship between the early maladaptive schemas and symptoms of obsessive-compulsive disorder in the University staff and between early maladaptive schemas and intolerance of uncertainty, and between intolerance of uncertainty and obsessive-compulsive symptoms in the University staff.
