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.
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.
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.
The results of our study show that cognitive flexibility is impaired in OCD patients with higher obsessive beliefs.
根据强迫症的认知模型，功能失调性信念在强迫症（OCD）症状的发作和维持中起着重要作用。预期具有较高强迫观念信念的强迫症患者在认知灵活性方面会有更大的缺陷。在本研究中，我们旨在探讨强迫症患者强迫观念信念水平与认知灵活性之间的关系。
使用《精神障碍诊断与统计手册》第四版轴I障碍的结构化临床访谈对50名强迫症患者和作为对照组的30名惊恐障碍患者进行评估和诊断。向所有患者发放社会人口统计学数据表格、贝克抑郁量表、贝克焦虑量表和威斯康星卡片分类测验（WCST）。向强迫症组发放耶鲁-布朗强迫量表和强迫信念问卷-44（OBQ-44）。根据聚类分析方法，将强迫症组分为两个亚组，即高强迫观念信念组（OCD-H）（n = 29）和低强迫观念信念组（OCD-L）（n = 21）。
根据WCST对亚组进行比较时；OCD-H组完成的类别数量在统计学上显著更低，总错误数、持续性错误数和非持续性错误数显著更高。
我们的研究结果表明，具有较高强迫观念信念的强迫症患者的认知灵活性受损。
