这项研究检验了厌恶敏感性在预测与污染相关的焦虑和行为回避方面的特异性。污染恐惧高（n = 26）和低（n = 30）的参与者完成了厌恶敏感性、污染认知（高估日常物品污染的可能性和严重性）、焦虑和抑郁的自我报告测量。然后，他们完成了三项随机呈现的基于污染的行为避免任务（BATS），其中包括接触用过的梳子、地板上的饼干和装满厕所水的便盆。结果表明，厌恶敏感性与对污染相关最佳可行技术的焦虑和回避反应显着相关。在控制了性别、污染恐惧群体成员身份、焦虑和抑郁因素后，这种关联基本上保持不变。污染认知也与 BAT 反应显着相关。然而，这种关系完全是由厌恶敏感性调节的。这些发现表明，厌恶敏感性与强迫症中常见的污染问题具有特定而强烈的关联。这些发现是在疾病避免模型的背景下讨论的。 (c) 2007 Elsevier Ltd. 保留所有权利。
This study examined the specificity of disgust sensitivity in predicting contamination-related anxiety and behavioral avoidance. Participants high (n = 26) and low (n = 30) in contamination fear completed self-report measures of disgust sensitivity, contamination cognitions (overestimation of the likelihood and severity of contamination from everyday objects), anxiety, and depression. They then completed three randomly presented contamination-based behavioral avoidance tasks (BATS) that consisted of exposure to a used comb, a cookie on the floor, and a bedpan filled with toilet water. Results indicated that disgust sensitivity was significantly associated with anxious and avoidant responding to the contamination-related BATs. This association remained largely intact after controlling for gender, contamination fear group membership, anxiety, and depression. Contamination cognitions were also significantly related to BAT responses. However, this relationship was fully mediated by disgust sensitivity. These findings indicate that disgust sensitivity has a specific and robust association with contamination concerns commonly observed in obsessive compulsive disorder. The findings are discussed in the context of a disease-avoidance model. (c) 2007 Elsevier Ltd. All rights reserved.
