The main aim was to perform a systematic literature review of studies investigating the factor structure of the Eating Disorder Examination-Questionnaire (EDE-Q), a widely used measure of eating pathology. Secondary aims were to summarize the quality of reporting of latent variable (factor) analyses in these studies and review support for different factor solutions.
Literature was identified through Scopus, Medline, PsycInfo, and ProQuest databases published up to February 23, 2022 and outreach via an international listserv. All studies published in English reporting factor analysis of the EDE-Q were included with few restrictions. Sixty studies including 63,389 participants met inclusion criteria.
The originally proposed four-factor solution received little empirical support, although few alternative models have been robustly evaluated. Items assessing shape and weight concerns frequently coalesce in factor solutions, suggesting that these constructs are closely related. Investigations of brief versions of the EDE-Q have produced more consistent findings, suggesting that these measures, particularly a seven-item version, might be useful alternatives to the full version. Quality of studies was reasonable, with important methodological elements of factor analysis often reported.
The findings are of relevance to practitioners and researchers, suggesting that the "original" factor structure of the EDE-Q should be reconsidered and that use of a seven-item version is to be encouraged.
Self-report questionnaires are widely used in the assessment of disordered eating. The current study found that there is little consensus about the structure of a common measure of eating psychopathology. There is more consistent support for a brief, seven-item, version assessing dietary restraint, body dissatisfaction, and overvaluation of weight and shape.
本研究旨在对调查饮食障碍问卷（EDE-Q）结构的研究进行系统综述，EDE-Q 是一种广泛用于评估进食障碍的常用方法。次要目的是总结这些研究中潜在变量（因子）分析报告的质量，并回顾对不同因子解决方案的支持。
通过 Scopus、Medline、PsycInfo 和 ProQuest 数据库，检索截至 2022 年 2 月 23 日发表的英语文献，并通过国际名录进行扩展搜索。纳入了报告 EDE-Q 因子分析的所有研究，限制条件较少。60 项研究共纳入 63389 名参与者。
最初提出的四因子结构几乎没有得到实证支持，尽管一些替代模型已经得到了稳健的评估。评估体型和体重问题的项目在因子分析中经常聚在一起，这表明这些结构密切相关。对 EDE-Q 简短版本的研究产生了更一致的结果，表明这些测量方法，特别是七项版本，可能是完整版本的有用替代方法。研究质量合理，因子分析的重要方法学要素经常得到报告。
这些发现与临床医生和研究人员有关，表明应重新考虑 EDE-Q 的“原始”因子结构，并鼓励使用七项版本。
自我报告问卷广泛用于评估饮食障碍。目前的研究发现，一种常见的进食心理病理学测量方法的结构没有达成共识。对于评估饮食限制、身体不满、对体重和体型的过度重视的简短的七项版本有更一致的支持。
