Theoretical models suggest that the emotion disgust or threat overestimates are important in the aetiology and maintenance of contamination-based obsessive–compulsive disorder. In the current study, both threat and disgust were manipulated and 115 non-clinical participants (mean age 20.46 years, 94 females) were randomly allocated to one of four conditions: high-disgust/low-threat (n = 29), high-disgust/high-threat (n = 29), low-disgust/low-threat (n = 27), and low-disgust/high-threat (n = 30). Participants completed a hierarchical Behavioural Avoidance Task (BAT). Those in the high-threat and high-disgust conditions completed less BAT steps and showed more latency to begin each step than those in the low-threat and low-disgust conditions. A significant interaction effect was observed for the high-disgust/high-threat condition as significantly more task avoidance was found. However, handwashing duration was not significantly different between the high and low-disgust conditions or the high and low-threat conditions. The overall low mean washing duration of 30 s possibly due to the testing conditions and/or the ethnic heterogeneity of the sample may account for these results. There were also no significant differences in the level of anxiety for participants in the high-threat compared with the low-threat conditions. It is possible that anxiety remained relatively low across conditions as a result of the graduated BAT. Future research and theoretical and clinical implications are discussed.

厌恶和威胁在污染相关强迫症中的作用
理论模型表明,情绪厌恶或威胁高估在基于污染的强迫症的病因和维持中很重要。在目前的研究中,威胁和厌恶都被操纵,115 名非临床参与者(平均年龄 20.46 岁,94 名女性)被随机分配到以下四种条件之一:高厌恶/低威胁(n = 29), 高厌恶/高威胁 (n = 29), 低厌恶/低威胁 (n = 27)和低厌恶/高威胁(n = 30)。参与者完成了分层的行为回避任务(BAT)。那些处于高威胁和高厌恶条件下的人完成的 BAT 步骤更少,并且比处于低威胁和低厌恶条件下的人开始每个步骤的延迟时间更长。在高厌恶/高威胁条件下观察到显着的交互效应,因为发现明显更多的任务回避。然而,洗手持续时间在高厌恶和低厌恶条件或高威胁和低威胁条件之间没有显着差异。可能由于测试条件和/或样本的种族异质性,30 秒的整体低平均洗涤持续时间可能解释了这些结果。与低威胁条件相比,高威胁参与者的焦虑水平也没有显着差异。由于已毕业的 BAT,焦虑可能在各种情况下保持相对较低。讨论了未来的研究以及理论和临床意义。
