The original, theoretically derived factor structure of the Eating Disorder Examination-Questionnaire (EDE-Q) has received limited empirical support and there is no consensus on an appropriate alternative. Moreover, there is a paucity of data on the factor structure of the EDE-Q across sexes. The goals of the current study were to evaluate models of the EDE-Q factor structure and to assess the best-fitting model for differences by sex. Twelve models were compared using confirmatory factor analysis in a sample of 940 undergraduates. Confirmatory factor analysis did not support the original factor structure. A four-factor model fit the data reasonably well with factors corresponding to themes of (a) dietary restraint, (b) preoccupation and restriction, (c) weight and shape concern, and (d) eating shame. The EDE-Q was found to be invariant by sex across all factors except Factor 3. The implications of these findings are discussed.
饮食失调问卷（EDE-Q）的原始理论推导因子结构得到的实证支持有限，对于替代结构也没有共识。此外，关于跨性别群体的 EDE-Q 因子结构的数据也很少。本研究的目的是评估 EDE-Q 因子结构的模型，并评估性别差异的最佳拟合模型。在一个由 940 名本科生组成的样本中，使用验证性因子分析比较了 12 种模型。验证性因子分析不支持原始因子结构。一个四因子模型可以很好地拟合数据，因子对应于（a）饮食限制、（b）专注和限制、（c）体重和体型关注、（d）饮食羞耻等主题。除了第三因子外，EDE-Q 在所有因子上都被发现具有性别不变性。讨论了这些发现的意义。
