The present study sought to examine patterns of habituation in exposure and response prevention (ERP) treatment of compulsive hand washing. Sub-clinical compulsive washers (n=27) with illness or non-illness primary threats were compared in order to detect potential differences in response to a single session of ERP. Changes in anxiety, disgust, and urge to wash were analyzed, and significant reductions in both anxiety and disgust were noted. Urge to wash significantly declined among washers primarily concerned with illness; among those concerned with non-illness threats, urge to wash did not significantly decline. Moreover, anxiety was found to decline when controlling for disgust and vice versa. Lastly, when both anxiety and disgust were entered into a model predicting changes in urge to wash, anxiety but not disgust predicted urge to wash for those with illness-related threats; for washers with non-illness threats, the findings were the reverse. Several clinical and theoretical implications are discussed.
本研究旨在探讨在强迫性洗手的暴露与反应阻止疗法（ERP）中习惯化的模式。对患有疾病或非疾病主要威胁的亚临床强迫性洗手者（n = 27）进行比较，以检测对单次ERP治疗反应的潜在差异。分析了焦虑、厌恶和洗手冲动的变化，发现焦虑和厌恶均显著降低。主要关注疾病的洗手者的洗手冲动显著下降；而在那些关注非疾病威胁的人中，洗手冲动没有显著下降。此外，发现控制厌恶时焦虑会下降，反之亦然。最后，当将焦虑和厌恶都纳入预测洗手冲动变化的模型时，对于有疾病相关威胁的人，焦虑而非厌恶预测了洗手冲动；对于有非疾病威胁的洗手者，结果则相反。文中讨论了若干临床和理论意义。
