Abstract: The Eating Disorder Examination Questionnaire (EDE-Q) is a widely used assessment of eating disorder psychopathology however, EDE-Q norms are yet to be provided within a nonclinical U.K. adult s le. Second, there is considerable disagreement regarding the psychometric properties of this measure. Several alternative factor structures have been previously proposed, but very few have subsequently validated their new structure in independent s les and many are often confined to specific subpopulations. Therefore, in the current study, we provide norms of the original four-factor EDE-Q structure, and subsequently assess the psychometric properties of the EDE-Q in females and males using a large nonclinical U.K. s le (total N = 2459). EDE-Q norms were consistently higher in females compared with males across all s les. Initial confirmatory factor analyses (CFA) did not support the original 4-factor structure for females or males (Phase 1). However, subsequent exploratory factor analyses (EFA) revealed a 3-factor structure as being the optimal fit for both females and males, using an 18-item and 16-item model, respectively (Phase 2). For females, the newly proposed 18-item structure was validated within an independent student s le and further validated in an additional nonstudent s le. The 16-item 3-factor male structure was also validated within an independent nonstudent s le, but was marginally below accepted fit indices within an independent student s le (Phase 3). Taken together, the above findings suggest that the EDE-Q factor structure may require further reassessment, with greater focus on the qualitative differences in interpretation of EDE-Q items between females and males.
