The role of danger expectancies in sub-clinical Obsessive-Compulsive Disorder (OCD) was examined in 18 undergraduate students who had displayed washing/contamination concerns. The perceived level of danger in a Behavioural Avoidance Test (BAT) involving a compound stimulus of potting soil, animal hair, food scraps, and raw meat was manipulated by varying the instructions participants were given at the commencement of the BAT. Participants were randomly allocated into a high-danger instruction condition or a low-danger instruction condition. Participants in the higher-danger instruction condition had higher mean ratings for anxiety and urge in wash, showed greater avoidance, and spent longer washing their hands at the completion of the task than participants in the low-danger instruction condition. However, only the differences in avoidance scores and post-BAT washing were statistically significant. These findings are discussed in relation to danger-based models of OCD.
在18名表现出洗涤/污染相关担忧的本科生中，研究了危险预期在亚临床强迫症（OCD）中的作用。在一项行为回避测试（BAT）中，通过改变参与者在测试开始时收到的指示，对涉及盆栽土、动物毛发、食物残渣和生肉的复合刺激的危险感知水平进行了操控。参与者被随机分配到高危险指示组或低危险指示组。与低危险指示组的参与者相比，高危险指示组的参与者在焦虑和洗涤冲动方面的平均评分更高，表现出更大的回避行为，并且在任务完成时洗手时间更长。然而，只有回避分数和测试后洗手时间的差异具有统计学意义。本文将结合基于危险的强迫症模型对这些发现进行讨论。
