Disgust has been implicated in the fear of contamination that is commonly observed in obsessive-compulsive disorder (OCD). However, basic and treatment-oriented research has shown that disgust is resistant to extinction among those with a fear of contamination. Consequently, there is growing interest in discovering novel approaches to targeting heightened disgust responding among those with OCD. Recent experimental research suggests that sexual arousal may inhibit disgust responding. Accordingly, the present study examines the effects of exposure to erotica on verbal reports of disgust and behavioral avoidance in a contamination-fearful sample of adults. Participants viewed sexually arousing, positively arousing, or neutral films and participated in a series of sexually relevant and non-sexually relevant behavioral approach tasks. Participants also gave ratings of disgust before and after completing each behavioral task. Although no group differences were observed for the number of steps completed on the behavioral approach tasks, those who viewed sexually arousing films reported significantly less change in disgust throughout the behavioral approach task compared to those who viewed positively arousing and neutral films. The potential clinical implications of the effects of sexual arousal on disgust responding in contamination-based OCD are discussed.
厌恶与强迫症(OCD)中常见的污染恐惧有关。然而,基础研究和以治疗为导向的研究表明,厌恶在有污染恐惧的人群中难以消退。因此,人们越来越有兴趣探索针对强迫症患者中过度厌恶反应的新方法。最近的实验研究表明,性唤起可能会抑制厌恶反应。据此,本研究考察了在有污染恐惧的成年样本中,观看色情内容对厌恶的言语报告和行为回避的影响。参与者观看了引起性唤起、积极唤起或中性的影片,并参与了一系列与性相关和与性无关的行为趋近任务。参与者还在完成每个行为任务前后对厌恶程度进行了评分。虽然在行为趋近任务中完成的步数上未观察到组间差异,但与观看引起积极唤起和中性影片的人相比,观看引起性唤起影片的人在整个行为趋近任务中报告的厌恶变化明显更少。本文讨论了性唤起对基于污染的强迫症中厌恶反应影响的潜在临床意义。
