BACKGROUND Recovery from dissociative identity disorder (DID) is associated with the process of integration, which includes an increasing sense of self-cohesion and ownership over one's own emotions. Emotion perception is a construction based on interplay between stored knowledge (past experience), and incoming sensory inputs, suggesting changes in emotion perception might occur at different levels of integration - but this remains unexplored. Therefore, we examined the association between integration, psychiatric symptoms, and facial emotion perception. We hypothesized higher integration would be associated with fewer psychiatric symptoms, and differences in the perception of emotions. METHODS Participants were 82 respondents to a cross-sectional web-based study. All participants met self-report cutoff scores for posttraumatic stress disorder (PTSD) and DID using the PTSD Checklist for DSM-5 and Multiscale Dissociation Inventory, respectively. Participants completed a psychometrically-matched test of facial emotion perception for anger, fear, and happiness called the Belmont Emotion Sensitivity Test. Participants also completed the Beck Depression Inventory II, Childhood Trauma Questionnaire, and Integration Measure, a validated measure of self-cohesion. RESULTS Higher integration scores were associated with lower depression, PTSD, and autobiographical memory disturbance scores. Repeated-measures ANCOVA confirmed integration significantly interacted with emotion category on the facial emotion perception task. Specifically, higher integration scores were associated with greater accuracy to fearful and angry faces. CONCLUSIONS While acknowledging the limitations of a cross-sectional design, our results suggest that the process of integration is associated with fewer psychiatric symptoms, and more accurate facial emotion perception. This supports treatment guidelines regarding integration as a therapeutic goal for DID.

较高的整合分数与分离性身份障碍的面部情绪感知差异相关。


背景技术从分离性身份障碍（DID）中恢复与整合过程相关，其中包括自我凝聚力和对自己情绪的所有权感的增强。情绪感知是基于存储的知识（过去的经验）和传入的感官输入之间相互作用的构建，这表明情绪感知的变化可能发生在不同的整合水平上 - 但这仍然未经探索。因此，我们研究了整合、精神症状和面部情绪感知之间的关联。我们假设更高的整合度与更少的精神症状以及情绪感知的差异相关。方法 参与者是一项横断面网络研究的 82 名受访者。所有参与者分别使用 DSM-5 的 PTSD 检查表和多尺度解离量表，达到了创伤后应激障碍 (PTSD) 和 DID 的自我报告截止分数。参与者完成了一项心理测量匹配的愤怒、恐惧和幸福的面部情绪感知测试，称为贝尔蒙特情绪敏感性测试。参与者还完成了贝克抑郁量表 II、童年创伤问卷和整合测量（一种经过验证的自我凝聚力测量）。结果 较高的整合分数与较低的抑郁、创伤后应激障碍和自传体记忆障碍分数相关。重复测量ANCOVA证实整合与面部情绪感知任务中的情绪类别显着相互作用。具体来说，整合分数越高，对恐惧和愤怒面孔的准确度越高。 结论虽然承认横截面设计的局限性，但我们的结果表明整合过程与较少的精神症状和更准确的面部情绪感知相关。这支持了将整合作为 DID 治疗目标的治疗指南。
