The present study utilizes multiple methods to examine the relationship between disgust and contamination-related obsessive-compulsive disorder (OCD) symptoms in an analogue sample. Questionnaire findings revealed that participants with high OCD contamination concerns showed stronger disgust sensitivity than did participants with low OCD contamination symptoms after controlling for negative affect. High OCD participants (N=30) also reported significantly more disgust than did low OCD participants (N=30) when exposed to a disgust-inducing video, whereas no significant between-group differences were detected on other negative emotional dimensions. Results from a series of disgust-specific behavioral avoidance tasks (BATs) revealed that high OCD participants demonstrated both less compliance and less approach behavior. Subsequent analysis also revealed that disgust sensitivity generally mediated avoidance on the BATs among high OCD subjects. High OCD participants also rated the BATs as more fearful and disgusting than did low OCD participants, with disgust generally emerging as the dominant emotional response. The results are consistent with a disgust-based, disease-avoidance approach in understanding contamination-related OCD themes.
本研究采用多种方法，在一个模拟样本中检验厌恶与污染相关的强迫症（OCD）症状之间的关系。问卷调查结果显示，在控制消极情绪后，有高度OCD污染担忧的参与者比有低度OCD污染症状的参与者表现出更强的厌恶敏感性。当暴露于一段引发厌恶的视频时，高OCD参与者（N = 30）报告的厌恶情绪也显著多于低OCD参与者（N = 30），而在其他负面情绪维度上未检测到显著的组间差异。一系列针对厌恶的行为回避任务（BATs）的结果显示，高OCD参与者表现出更低的依从性和更少的趋近行为。后续分析还表明，厌恶敏感性通常在高OCD受试者的BATs回避行为中起中介作用。高OCD参与者对BATs的恐惧和厌恶程度也高于低OCD参与者，厌恶情绪通常是主要的情绪反应。这些结果与基于厌恶的疾病回避方法一致，有助于理解与污染相关的OCD主题。
