本研究的第一个目的是提供规范的饮食失调检查问卷（EDE-Q）在一个多样化的和大型的临床样本的个人饮食失调（艾德），和一般人群样本没有ED。规范的个人肥胖没有艾德也提供了，作为一个更相关的比较组的个人暴食症。第二个目的是探讨EDE-Q的区分效度。艾德女性（N=935）、一般人群中无艾德的女性（N=235）和无艾德的肥胖女性（N=321）样本完成了EDE-Q探索性因素分析，但不支持EDE-Q的理论4个分量表。为三个样本中的每一个提供了EDE-Q总体评分的标准。在艾德样本中，分别为不同艾德诊断的患者提供标准。受试者操作特征分析显示，EDE-Q总体评分在区分患有艾德的个体与没有ED的个体方面高度准确，并且在区分患有暴食症的个体与患有肥胖症的个体方面中等准确。所提出的规范有助于更准确地解释EDE-Q评分，提供了艾德精神病理学严重程度的指数。此外，这些标准可用于评估治疗期间的临床显著变化。此外，本研究表明，当使用其整体评分时，EDE-Q是评估艾德精神病理学水平的有效工具。(C)2012爱思唯尔有限公司保留所有权利。
The first aim of this study was to provide norms for the Eating Disorder Examination Questionnaire (EDE-Q) in a diverse and large clinical sample of individuals with an eating disorder (ED), and a general population sample without an ED. Norms for individuals with obesity without an ED were also provided, as a more relevant comparison group for individuals with binge eating disorder. The second aim was to investigate the discriminative validity of the EDE-Q. A sample of females with an ED (N=935), women from the general population without an ED (N=235), and obese females without an ED (N=321) completed the EDE-Q Explorative factor analyses did not support the theorized four subscales of the EDE-Q. Norms for EDE-Q global scores were provided for each of the three samples. Within the ED sample, norms were provided separately for patients with different ED diagnoses. Receiver operating characteristic analyses showed the EDE-Q global score to be highly accurate in discriminating individuals with an ED from those without, and moderately accurate in discriminating individuals with binge eating disorder from those with obesity. The presented norms contribute to a more accurate interpretation of EDE-Q scores, providing an index of the severity level of ED psychopathology. Furthermore, these norms can be used to assess clinical significant change during treatment. In addition, this study demonstrates that the EDE-Q when using its global score, is a valid instrument to assess levels of ED psychopathology. (C) 2012 Elsevier Ltd. All rights reserved.
