目的进食障碍检查问卷（EDE-Q）是一种广泛使用的进食障碍行为和态度的自我报告测量工具。最近的研究利用验证性因素分析（CFA）提出了替代和更短的形式。本研究的目的是比较EDE-Q的完整版本和几个建议的简短形式（7题、8题和18题）的同时效度、聚合效度和区分效度，因素结构，方法来自两个进食障碍临床样本的参与者（N = 175和38）和非临床样本（N = 3，413）完成了一系列测量，包括葡萄牙语版的EDE-Q。结果所有形式的EDE-Q都表现出良好的内部一致性，彼此之间高度相关（r > .90），与不同的饮食精神病理学指标相关（r > .80）。所有的EDE-Q形式都能够区分病例和对照组，具有中等至高的准确性，并对变化敏感。CFA未能支持所有的EDE-Q形式的因素结构，除了7-item form.Discussion-本研究提供了实证背景，不同形式的EDE-Q之间的选择。研究结果表明，对于非临床和临床研究，包括治疗变化和结局的研究，可以使用EDE-Q的缩写形式。当需要更少耗时的替代方案时，较短的版本是一种可行的替代方案，例如快速筛查进食障碍精神病理学或逐节进行治疗监测。
Objective The Eating Disorder Examination - Questionnaire (EDE-Q) is a widely used self-report measure of eating-disordered behaviors and attitudes. Recent studies utilizing confirmatory factor analyses (CFA) have proposed alternative and shorter forms. The aim of this study was to compare the full-length version of the EDE-Q and several proposed short forms (7-item, 8-item, and 18-item) in terms of their psychometric properties, including concurrent, convergent and discriminant validity, factor structure, and sensitivity to change.Methods Participants from two eating-disorder clinical samples (N = 175 and 38) and from a nonclinical sample (N = 3,413) completed a battery of measures, including the Portuguese version of the EDE-Q. Analyses compared psychometric properties of the available short forms of the EDE-Q among each other.Results All forms of the EDE-Q showed good internal consistency values, correlated highly among each other (r > .90) and with different measures of eating psychopathology (r > .80). All EDE-Q forms were able to distinguish between cases and controls with moderate-to-high accuracy and were sensitive to change. CFA failed to support the proposed factor structure for all the EDE-Q forms, except for the 7-item form.Discussion The present study provides empirical background for choosing between different forms of the EDE-Q. Findings indicate that for nonclinical and for clinical research, including studies of treatment change and outcome, the short forms of the EDE-Q can be used. A shorter version is a viable alternative when less time-consuming alternatives are needed, such to quickly screen for eating-disorder psychopathology or to perform session-by-session treatment monitoring.
