Abstract: The Eating Disorder Examination Questionnaire (EDE-Q) 1 is one of the most widely used self-report measures for assessing eating disorder (ED) psychopathology.It consists of 22 items divided into four subscales: Restraint, Eating Concern, Shape Concern, and Weight Concern, along with six items that measure key ED behaviors, such as binge eating, purging, and excessive exercising.However, the original four-factor model of the EDE-Q (the EDE-Q original) has received limited empirical support. 2 With its length of 28 items, the EDE-Q may be considered too burdensome when a shorter instrument is needed.Studies utilizing exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) have proposed shorter forms of the EDE-Q for screening or assessing treatment progress and outcomes.2 Recent studies 2,3 suggest that the EDE-Q7 4 can effectively be used for clinical and nonclinical research.Only two articles have examined the dimensionality of the EDE-Q in the Japanese population.5,6 Mitsui et al. 5 found a fourfactor EDE-Q model (the EDE-Q Mitsui) that yielded four subscales.Otani et al. 6 noted that while the item assignments in the two Japanese models were similar, they differed from Western models, indicating potential cultural differences in the dimensionality of the EDE-Q between Japan and Western countries.To our knowledge, no articles have addressed the EDE-Q short forms in Japanese samples.Accordingly, a short form of the EDE-Q was developed, retaining the four-factor structure of the EDE-Q Mitsui.5 The criteria for the shortened scales were: (a) to limit the number of items to lessen the burden on participants, (b) to ensure each factor included items from
