The Eating Disorder Examination - Questionnaire Short (EDE-QS) was developed as a 12-item version of the Eating Disorder Examination Questionnaire (EDE-Q) with a 4-point response scale that assesses eating disorder (ED) symptoms over the preceding 7 days. It has demonstrated good psychometric properties at initial testing. The purpose of this brief report is to determine a threshold score that could be used in screening for probable ED cases in community settings.
Data collected from Gideon et al. (2016) were re-analyzed. In their study, 559 participants (80.86% female; 9.66% self-reported ED diagnosis) completed the EDE-Q, EDE-QS, SCOFF, and Clinical Impairment Assessment (CIA). Discriminatory power was compared between ED instruments using receiver operating characteristic (ROC) curve analyses.
A score of 15 emerged as the threshold that ensured the best trade-off between sensitivity (.83) and specificity (.85), and good positive predictive value (.37) for the EDE-QS, with discriminatory power comparable to other ED instruments.
The EDE-QS appears to be an instrument with good discriminatory power that could be used for ED screening purposes.
饮食障碍问卷-短表（EDE-QS）是作为饮食障碍问卷（EDE-Q）的 12 项版本开发的，采用 4 点反应量表，评估过去 7 天的饮食障碍（ED）症状。在最初的测试中，它已经表现出了良好的心理测量学特性。本简要报告的目的是确定一个可以在社区环境中用于筛查可能的 ED 病例的阈值分数。
重新分析了 Gideon 等人（2016 年）收集的数据。在他们的研究中，559 名参与者（80.86%为女性；9.66%自我报告 ED 诊断）完成了 EDE-Q、EDE-QS、SCOFF 和临床损伤评估（CIA）。使用受试者工作特征（ROC）曲线分析比较了 ED 工具之间的区分能力。
15 分是 EDE-QS 的最佳阈值分数，它在敏感性（0.83）和特异性（0.85）之间实现了良好的权衡，EDE-QS 的阳性预测值（0.37）也较好，其区分能力与其他 ED 工具相当。
EDE-QS 似乎是一种具有良好区分能力的工具，可用于 ED 筛查目的。
