Symptoms of anhedonia, or deficits in the ability to experience positive affect, are increasingly recognized as an outcome of traumatic stress. Herein we demonstrate a phenomenon of "negative affective interference", specifically, negative affective responses to positive events, in association with childhood trauma history. Young adults (n=99) completed a Hedonic Deficit & Interference Scale (HDIS), a self-report measure developed for this study, as well as a modified version of the Fawcette-Clarke Pleasure Capacity Scale that assessed not only positive but also negative affective responses to positive events. The two assessment approaches demonstrated convergent validity and predicted concurrent individual differences in trait positive and negative affect, and extraversion and neuroticism. Histories of childhood emotional and sexual abuse were differentially associated with negative affective responses to positive events. Future research and clinical directions are discussed.
快感缺失的症状，或体验积极情绪的能力缺陷，越来越被认为是创伤应激的结果。在此，我们展示了一种“负性情绪干扰”的现象，即对积极事件产生负性情绪反应，与儿童期创伤史有关。年轻成年人（n=99）完成了快感缺失和干扰量表（HDIS），这是本研究开发的一种自我报告量表，以及福塞特-克拉克愉悦能力量表的一个修改版本，该量表不仅评估了对积极事件的积极情绪反应，还评估了消极情绪反应。这两种评估方法具有一致性，预测了特质积极和消极情绪、外向性和神经质的个体差异。童年期情感和性虐待史与对积极事件的负性情绪反应存在差异。讨论了未来的研究和临床方向。
