The Eating Disorder Questionnaire-Online (EDQ-O) is an online self-report questionnaire, which was developed specifically to provide a DSM-IV-TR classification of anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), and eating disorder not otherwise specified (EDNOS), without using a face-to-face clinical interview.
The purpose of the present study was to examine the psychometric quality of the EDQ-O.
The validity of the EDQ-O was determined by examining the agreement with the diagnoses obtained from the Longitudinal, Expert, and All DATA (LEAD) standard. Participants included 134 new patients of a specialist center for eating disorders located in the Netherlands.
Assessment of the validity of the EDQ-O yielded acceptable to good AUC (area under the receiver operating characteristic curve) values with a range from 0.72 to 0.83. Most other diagnostic efficiency statistics were also good except for a low sensitivity for AN (0.44), a low positive predictive value for BN (0.50), and a relatively low sensitivity for BED (0.66).
The results of the present study suggest that the EDQ-O performs acceptably as a diagnostic instrument for all DSM-IV-TR eating disorder classifications. However, suggestions are made to further improve the validity of the EDQ-O.
饮食失调问卷在线版（EDQ - O）是一种在线自我报告问卷，专门用于在不进行面对面临床访谈的情况下，对神经性厌食症（AN）、神经性贪食症（BN）、暴饮暴食症（BED）以及未另行规定的饮食失调（EDNOS）进行《精神疾病诊断与统计手册》第四版修订版（DSM - IV - TR）分类。
本研究旨在检验EDQ - O的心理测量质量。
通过检查与从纵向、专家和所有数据（LEAD）标准获得的诊断结果的一致性来确定EDQ - O的有效性。参与者包括荷兰一家饮食失调专科中心的134名新患者。
对EDQ - O有效性的评估得出了可接受至良好的受试者工作特征曲线下面积（AUC）值，范围为0.72至0.83。除了AN的低敏感性（0.44）、BN的低阳性预测值（0.50）以及BED的相对低敏感性（0.66）外，大多数其他诊断效率统计数据也良好。
本研究结果表明，EDQ - O作为所有DSM - IV - TR饮食失调分类的诊断工具表现尚可。然而，也提出了进一步提高EDQ - O有效性的建议。
