The relationship between symptom dimensions and cognitive features in obsessive compulsive disorder

In this study, it was aimed to determine the cognitive differences specific to symptom dimensions of obsessive-compulsive disorder (OCD) and investigate the relationship between symptom dimensions and cognitive features. The study included 100 OCD patients and 100 controls who applied to the Psychiatry Clinic of Diskapi Training and Research Hospital. Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Dimensional Obsession Compulsion Scale (DOCS), Anxiety Sensitivity Index-3 (ASI-3), Obsessive Beliefs Questionnaire-44 (OBQ-44), Cognitive Fusion Questionnaire (CFQ) was used to evaluate the patients. A significant positive correlation between DOCS contamination and other cognitive features except ASI-physical and ASI-social. A significant positive correlation was found between all other sub-dimensions and all cognitive features examined. In the hierarchical regression analysis, ASI-cognitive and OBQ-responsibility for DOCS-harm avoidance; ASI-cognitive, OBQ-responsibility, CFQ for DOCS-unacceptable thoughts; ASI-cognitive, and CFQ for DOCS-symmetry were found to be a significant predictor. Our results were shown that some cognitive features were more closely related to some symptom dimensions and even predicted symptom dimensions.
