The Eating Disorder Examination-Questionnaire (EDE-Q) is one of the most widely used tools to assess the core psychopathology of eating disorders (ED). However, recent empirical findings did not support the original four-factor structure. The aims of the present study were to investigate the factor structure of the EDE-Q in Japanese ED patients, to test the reliability and convergent validity of the EDE-Q, to examine group differences between various ED groups and healthy participants, and to explore the main behavioral features of Japanese ED patients using the newly developed Japanese version of EDE-Q.
A total of 148 ED patients and 469 healthy participants completed the EDE-Q, Eating Attitudes Test-26 (EAT-26), and Eating Disorder Inventory-2 (EDI-2). The factor structure, reliability, and validity of the EDE-Q were assessed in ED patients. Group differences were assessed using the new Japanese version of the EDE-Q (EDE-Q-J).
The EDE-Q-J had three factors. Cronbach's alphas ranged from 0.83 to 0.93. Total score and subscale scores of "Dieting" and "Bulimia and Food Preoccupation" of EAT-26 and of "Drive for Thinness," "Body Dissatisfaction," and "Bulimia" of EDI-2 correlated with the global score and three subscale scores of the EDE-Q-J.
For Japanese female ED patients, the EDE-Q-J had three subscales that were not consistent with the original subscales, but were interpretable. It demonstrated sufficient reliability and validity. Japanese female patients with restricting-type anorexia nervosa (AN-R) displayed less dissatisfaction with shape and weight than healthy participants. AN-R patients in Japan might present with a non-fat-phobic symptom profile.
饮食障碍问卷（EDE-Q）是评估饮食障碍（ED）核心病理的最常用工具之一。然而，最近的实证研究结果并不支持其最初的四因素结构。本研究的目的是探讨日本 ED 患者中 EDE-Q 的因子结构，检验 EDE-Q 的信度和聚合效度，比较各种 ED 组与健康对照组之间的差异，并使用新开发的 EDE-Q 日本版探索日本 ED 患者的主要行为特征。
共 148 名 ED 患者和 469 名健康参与者完成了 EDE-Q、饮食态度测试 26 项（EAT-26）和饮食障碍量表 2（EDI-2）。在 ED 患者中评估了 EDE-Q 的因子结构、信度和效度。使用新的日本版 EDE-Q（EDE-Q-J）评估组间差异。
EDE-Q-J 具有三个因子。Cronbach's α 值范围为 0.83 至 0.93。EAT-26 的“节食”和“贪食与食物关注”总分及分量表得分，以及 EDI-2 的“瘦驱”、“身体不满”和“贪食”分量表得分与 EDE-Q-J 的总分和三个分量表得分相关。
对于日本女性 ED 患者，EDE-Q-J 具有三个与原始分量表不一致但可解释的分量表。它具有足够的信度和效度。日本限制型神经性厌食症（AN-R）患者的身体形状和体重不满程度低于健康参与者。日本的 AN-R 患者可能表现出非肥胖恐惧症的症状特征。
