Objective: Recent studies have emphasized the important role of cognitive beliefs in etiology and maintenance of obsessive-compulsive disorder (OCD). OCD has different subtypes, but the specific role of cognitive beliefs in OCD symptomatology is not clear. The aim of the current study was to determine whether the cognitive factors proposed by Obsessive Compulsive Cognitions Working Group (OCCWG) could specifically predict subtypes of OCD.
Method: The question was investigated in a sample of 208 university students (mean age = 21, SD = 1.6). The target population was selected by cluster sampling. All participants completed two questionnaires including Obsessive Beliefs Questionnaire (OBQ-44) and Obsessive Compulsive Inventory-Revised (OCI-R). Data were analyzed using descriptive statistics and regression analysis.
Results: Regression analysis demonstrated that “responsibility/ threat over estimation” was a significant predictor of obsessive and compulsive behaviors and predicted washing, checking, obsessing, hoarding, and neutralizing subtypes of OCD. Furthermore, “perfectionism and intolerance of uncertainty” was the most significant predictor of ordering and hoarding while “importance/ control of thought” predicted ordering only.
Conclusion: This study found evidence in support of Salkovskis’ cognitive theory about the central role of inflated responsibility beliefs in developing different subtypes of OCD. Besides, the results revealed those other cognitive beliefs had less important role in the development of OCD symptoms.
