OBJECTIVES
Obsessive-compulsive disorder (OCD) is a debilitating mental disorder characterized by persistent and intrusive thoughts accompanied by repetitive mental or physical acts. While both intolerance of uncertainty and emotion-related impulsivity have been consistently evidenced as cognitive risk factors of OCD, no studies have considered their joint effects. The current study examined the interaction between intolerance of uncertainty and two forms of emotion-related impulsivity-including both a behavioural and cognitive form-in predicting OCD symptoms.
DESIGN
Cross-sectional data were collected online from community-based adult participants.
METHODS
Participants (N = 673) completed a battery of self-report measures of OCD symptom severity, intolerance of uncertainty, and emotion-related impulsivity.
RESULTS
The behavioural form of emotion-related impulsivity positively moderated the relationship between intolerance of uncertainty and OCD symptoms. Elevated levels of both factors predicted the most severe symptoms, particularly checking, washing, and obsessing. This interaction effect was not found for the cognitive form of emotion-related impulsivity, which still emerged as a unique predictor of OCD symptom severity, specifically obsessing symptoms.
CONCLUSIONS
Current findings furthered the understanding of the link between intolerance of uncertainty and OCD symptoms by highlighting the role of emotion-related impulsivity. When uncertainty triggers distress in individuals with high intolerance of uncertainty, the urge to behaviourally alleviate this distress could promote the use of maladaptive obsessions and compulsions, leading to greater OCD symptoms. Results also indicated the potentially differential effects from the behavioural versus cognitive forms of emotion-related impulsivity on different symptom domains, and the mechanistic link here is worthy of further investigation.
目的
强迫症（OCD）是一种使人衰弱的精神障碍，其特征是持续存在且侵入性的思维，并伴有重复的精神或身体行为。虽然无法忍受不确定性和与情绪相关的冲动一直被证明是 OCD 的认知风险因素，但没有研究考虑它们的共同作用。本研究考察了无法忍受不确定性与两种与情绪相关的冲动形式（包括行为和认知形式）在预测 OCD 症状中的相互作用。
设计
在线从基于社区的成年参与者中收集横断面数据。
方法
参与者（N=673）完成了一系列自我报告的 OCD 症状严重程度、无法忍受不确定性和与情绪相关的冲动的测量。
结果
与情绪相关的冲动的行为形式正向调节了无法忍受不确定性与 OCD 症状之间的关系。这两个因素的升高水平都预测了最严重的症状，特别是检查、洗涤和痴迷。与情绪相关的冲动的认知形式没有发现这种交互作用，它仍然是 OCD 症状严重程度的独特预测因素，特别是痴迷症状。
结论
目前的研究结果通过强调与情绪相关的冲动的作用，进一步了解了无法忍受不确定性与 OCD 症状之间的联系。当无法忍受不确定性的个体感到不安时，减轻这种不安的行为冲动可能会促使他们使用适应不良的痴迷和强迫行为，从而导致更严重的 OCD 症状。研究结果还表明，与情绪相关的冲动的行为和认知形式对不同的症状领域可能有不同的影响，这里的机制联系值得进一步研究。
