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.
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.
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.
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.
近期研究强调了认知信念在强迫症（OCD）病因及维持过程中的重要作用。强迫症有不同亚型，但认知信念在强迫症症状学中的具体作用尚不清楚。本研究的目的是确定强迫认知工作组（OCCWG）提出的认知因素是否能特异性地预测强迫症的亚型。
在208名大学生样本（平均年龄 = 21岁，标准差 = 1.6）中对该问题进行了调查。目标人群通过整群抽样选取。所有参与者完成了两份问卷，包括强迫信念问卷（OBQ - 44）和修订版强迫症状量表（OCI - R）。使用描述性统计和回归分析对数据进行分析。
回归分析表明，“责任/威胁高估”是强迫行为的显著预测因子，可预测强迫症的洗涤、检查、强迫观念、囤积和中和亚型。此外，“完美主义和对不确定性的不容忍”是排序和囤积的最显著预测因子，而“思想的重要性/控制”仅预测排序。
本研究发现证据支持索尔科夫斯基的认知理论，即夸大的责任信念在不同亚型强迫症发展中起核心作用。此外，结果显示其他认知信念在强迫症症状发展中的作用较小。
