Emerging evidence implicates important roles of poor distress tolerance and heightened emotional reactivity in obsessive-compulsive disorder. To date, investigations have relied mostly on self-report measures, and we sought to extend the literature by examining the relationship between OC symptoms and distress tolerance, as well as emotional reactivity, using three laboratory assessments. Nonclinical participants (N=167) viewed emotional films associated with four different negative emotions and also completed mirror tracing and handgrip persistence tasks. Greater obsessions scores were predictive of poorer emotional tolerance for a sad film and shorter persistence on the mirror tracing task. Among men only, obsessions were negatively correlated with persistence on the handgrip task. Associations between increased emotional reactivity and washing symptoms also emerged. These findings provide further evidence for the role of poor distress tolerance in obsessions and suggest heightened emotional reactivity may play a role in compulsive washing.
越来越多的证据表明，较差的痛苦容忍度和较高的情绪反应性在强迫症中起着重要作用。迄今为止，研究主要依赖于自我报告的测量方法，我们试图通过使用三种实验室评估来扩展文献，研究 OC 症状与痛苦容忍度以及情绪反应性之间的关系。非临床参与者（N=167）观看了与四种不同负性情绪相关的情绪影片，还完成了镜像追踪和手握耐力任务。更多的强迫观念分数预示着对悲伤影片的情绪容忍度较差，且在镜像追踪任务上的坚持时间较短。仅在男性中，强迫观念与手握耐力任务的坚持时间呈负相关。情绪反应性增加与洗涤症状之间也存在关联。这些发现进一步证明了较差的痛苦容忍度在强迫观念中的作用，并表明情绪反应性升高可能在强迫性洗涤中起作用。
