Abstract
INTRODUCTION: It is known that dysfunctional beliefs are important in the onset and maintenance of symptoms of Obsessive Compulsive Disorder (OCD) according to the cognitive model of OCD. OCD patients with higher obsessive beliefs would be expected to have greater deficits in cognitive flexibility. In this study, we aimed to examine the relationship between obsessive belief levels and cognitive flexibility in OCD patients. METHODS: Patients with OCD (50) and Panic Disorder (30) as a control group were evaluated and diagnosed using Structured Clinical Interview for DSM-IV Axis I Disorders. A socio-demographic data form, Beck Depression Inventory, Beck Anxiety Inventory and Wisconsin Card Sorting Test (WCST) were administered to all the patients. The Yale-Brown Obsessive Compulsive Scale and Obsessive Beliefs Questionnaire-44 (OBQ-44) were administered to the OCD group. The OCD group was divided into two subgroups as higher obsessive beliefs (OCD-H) (n=29) and lower obsessive beliefs (OCD-L) (n=21) according to a cluster analytic approach. RESULTS: When the subgroups were compared according to WCST; the number of completed categories was statistically significantly lower, and the numbers of total errors, perseverative errors and non-perseverative errors were significantly higher in the OCD-H group. CONCLUSION: The results of our study show that cognitive flexibility is impaired in OCD patients with higher obsessive beliefs.
