Abstract

Background and Objective: Several studies revealed that disgust as an emotional response underlies the contamination fears in Contamination Obsessive Compulsive Disorder (OCD). Other studies supported the role of cognitions related to contagion and disease in contamination OCD. The present study aimed to integrate these two lines of evidence. To this end, regarding the concept of the behavioral immune system, it was investigated whether perceived vulnerability to infectious disease, as a cognitive component of the behavioral immune system, can moderate the relation between disgust, as the emotional component of this system, and symptoms of contamination OCD. Materials and Methods: This cross-sectional study was conducted on 350 university students in Tehran University through cluster random sampling. The participants were asked to complete the Persian version of the disgust scale, perceived vulnerability to disease questionnaire, and Vancouver contamination subscale. The data were analyzed utilizing hierarchical regression analysis and post hoc tests. Results: The results revealed that perceived vulnerability to infectious disease moderated the relationship between the feeling of disgust and fear of contamination. According to the results, perceived infectability subscale which measures perceived weakness of one's immune system with more accuracy, can also exacerbate the relationship between the feeling of disgust and fear of contamination. Conclusion: The results of this study facilitate the understanding of the effect of disgust on fear of contamination, especially the role of cognitions about contagion and disease in potentiating the relation between disgust and contamination OCD. Moreover the obtained results generally provide evidence for the disease-avoidance theory in disgust and support the possible hyperactivity of the behavioral immune system in contamination OCD.
传染病易感性在厌恶与污染恐惧关系中的调节作用研究
背景和目的:几项研究表明,厌恶作为一种情绪反应,是污染强迫症(OCD)中污染恐惧的基础。其他研究支持与传染和疾病相关的认知在污染强迫症中的作用。本研究旨在整合这两条证据线。为此,关于行为免疫系统的概念,研究了作为行为免疫系统认知组成部分的对传染病的感知脆弱性是否可以调节作为该系统情感组成部分的厌恶与污染强迫症症状之间的关系。材料和方法:本研究采用整群随机抽样的方法,对德黑兰大学350名大学生进行了横断面研究。参与者被要求完成波斯版的厌恶量表、对疾病的感知脆弱性问卷和温哥华污染分量表。利用层次回归分析和事后检验对数据进行分析。结果:研究结果表明,对传染病的易感性调节了厌恶感和对污染的恐惧感之间的关系。根据研究结果,感知可感染性分量表更准确地衡量一个人免疫系统的感知弱点,也会加剧厌恶感和对污染的恐惧之间的关系。结论:本研究的结果有助于理解厌恶对污染恐惧的影响,特别是对传染病和疾病的认知在增强厌恶与污染强迫症之间关系中的作用。此外,所获得的结果通常为厌恶中的疾病回避理论提供了证据,并支持污染强迫症中行为免疫系统可能的过度活跃。
