Cognitiveschemas and symptoms of obsessive-compulsive disorder:a model with the mediating roleof intolerance of uncertainty

The aim of present study was to investigate the mediating effect of intolerance of uncertainty in the relationship between cognitive schemas and symptoms of obsessive-compulsive disorder in Khayyam University staff and its effect on their practice.

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.

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.

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.
