患有自闭症谱系障碍（ASD）的个体通常表现为明显的情绪失调，需要治疗，但很难测量。情绪失调量表（EDI）使用患者报告结果测量信息系统（PROMIS (R)）开发的方法创建，以捕获情绪调节不良的可观察指标。1755名青少年ASD照顾者完成了66个备选EDI项目，最后通过经典测试理论和项目反应理论（IRT）分析选出30个项目。分析确定了两个因素：(a)反应性，其特征是强烈的、迅速升级的、持续的、调节不良的消极情绪反应；(b)烦躁不安，其特征是快感缺乏、悲伤和紧张。最后的项目没有显示基于性别、年龄、智力能力或语言能力的差异项目功能（DIF）。由于最终项目是使用IRT校准的，因此即使少量项目也能提供高精度，从而最大限度地减少了被调查者的负担。IRT共校准EDI与相关测量显示其优势在评估情绪失调的严重程度，只有7个项目。EDI的有效性得到了专家评审的支持，它与相关构念（如焦虑和抑郁症状、攻击）的关联，与社区ASD样本相比，精神科ASD住院患者的得分更高，并且证明了重测的稳定性和对变化的敏感性。总之，EDI为临床评估、监测和研究任何认知或语言能力水平的青少年ASD患者的情绪失调提供了一种有效而敏感的方法。自闭症杂志，2018,11:928-941。(c) 2018国际自闭症研究学会，Wiley期刊，Inc.Lay摘要本文描述了一种新的情绪控制不良的测量方法，称为情绪失调量表（EDI）。1755名青少年自闭症患者的护理人员完成候选项目，并应用先进的统计技术来确定最佳的最终项目。EDI的独特之处在于它捕捉到了自闭症谱系障碍中常见的情绪问题，适用于非语言和语言的青少年。它是一种有效而敏感的方法，可用于青少年ASD的临床评估、监测和研究。
Individuals with autism spectrum disorder (ASD) often present with prominent emotion dysregulation that requires treatment but can be difficult to measure. The Emotion Dysregulation Inventory (EDI) was created using methods developed by the Patient-Reported Outcomes Measurement Information System (PROMIS (R)) to capture observable indicators of poor emotion regulation. Caregivers of 1,755 youth with ASD completed 66 candidate EDI items, and the final 30 items were selected based on classical test theory and item response theory (IRT) analyses. The analyses identified two factors: (a) Reactivity, characterized by intense, rapidly escalating, sustained, and poorly regulated negative emotional reactions, and (b) Dysphoria, characterized by anhedonia, sadness, and nervousness. The final items did not show differential item functioning (DIF) based on gender, age, intellectual ability, or verbal ability. Because the final items were calibrated using IRT, even a small number of items offers high precision, minimizing respondent burden. IRT co-calibration of the EDI with related measures demonstrated its superiority in assessing the severity of emotion dysregulation with as few as seven items. Validity of the EDI was supported by expert review, its association with related constructs (e.g., anxiety and depression symptoms, aggression), higher scores in psychiatric inpatients with ASD compared to a community ASD sample, and demonstration of test-retest stability and sensitivity to change. In sum, the EDI provides an efficient and sensitive method to measure emotion dysregulation for clinical assessment, monitoring, and research in youth with ASD of any level of cognitive or verbal ability.

Caregivers of 1,755 youth with ASD completed candidate items, and advanced statistical techniques were applied to identify the best final items. The EDI is unique because it captures common emotional problems in ASD and is appropriate for both nonverbal and verbal youth. It is an efficient and sensitive measure for use in clinical assessments, monitoring, and research with youth with ASD.
