述情障碍与精神和身体健康障碍的风险增加有关，但现有的评估完全依赖于自我报告。本研究的主要目的是开发和实施一个基于绩效的任务，旨在描述和量化一个人的描述情绪体验和自我报告的述情障碍之间的关系。具体来说，我们研究了基于性能的措施，影响标签自己的情绪，情绪粒度和辩证法。健康受试者（N=108）完成了多伦多述情障碍量表-20项问卷。参与者观看了一系列标准化的电影片段，以引出离散的情绪状态。在每个片段之后，他们指出他们经历的“最多”的情绪，并对一系列非主要情绪进行评级，这些情绪构成了情绪粒度和辩证法的指数。述情障碍与回忆性电影片段后报告经历“无情绪”的倾向增加、负面情绪粒度减少和经历情绪的辩证性有关。TAS-20分量表中的每一个都与一组独特的情感相关因素相关。在一个健康的人群中，述情障碍与情绪状态的意识降低、消极（但不是积极）情绪的辩证性和粒度减少有关。我们基于表现的评估通过强调情绪意识、消极情绪粒度和辩证法的核心重要性，丰富了对述情障碍机制的理解。
Alexithymia is associated with increased risk for mental and physical health disorders but available assessments rely exclusively on self-report. The major aim of the current study was to develop and implement a performance-based task designed to characterize and quantify the relationship between one’s description of emotional experience and self-reported alexithymia. Specifically, we examined performance-based measures of affect labeling of one’s own emotions, emotional granularity and dialecticism. Healthy participants (N=108) completed the Toronto Alexithymia Scale–20 Item Questionnaire. Participants viewed a series of film clips standardized to elicit discrete emotional states. After each clip, they indicated the emotion they experienced “the most” and rated a list of non-primary emotions, which formed indices of emotional granularity and dialecticism. Alexithymia was associated with increased tendency to report experiencing “no emotion” following evocative film clips, reduced negative emotional granularity and dialecticism of experienced emotions. TAS-20 subscales were each associated with a unique set of emotional correlates. In a healthy population, alexithymia is associated with reduced awareness of emotional states, and reduced dialecticism and granularity of negative (but not positive) emotions. Our performance-based assessment enriches understanding of the mechanisms underlying alexithymia by underscoring the central importance of emotion awareness, negative emotional granularity and dialecticism.
