Abstract
ObjectiveThe Eating Disorders Examination–Questionnaire (EDE-Q) is widely used but time-consuming to complete. In recent years, the advantages and disadvantages of several brief versions have therefore been investigated. A seven-item scale (EDE-Q-7) has excellent psychometric properties but excludes items on bingeing and purging. This study aimed to evaluate a thirteen-item scale (EDE-Q-13) including items on bingeing and purging.MethodParticipants were 1160 (188 [11.4%] males) community volunteers of mean age 28.79 ± 9.92. They completed the full EDE-Q in Hebrew, as well as measures of positive body experience, social and emotional connection, life satisfaction, positive and negative affect and positive eating. The six EDE-Q items about bingeing and purging, recoded to correspond to the response categories of the other EDE-Q questions, were added to the EDE-Q-7, resulting in the EDE-Q-13.ResultsConfirmatory factor analysis confirmed the hypothesized EDE-Q-13 structure, including the bingeing and purging subscales. Strong positive correlations were found between the EDE-Q-13 and the original EDE-Q scores. The EDE-Q-13 showed convergent validity with related measures.ConclusionsThe EDE-Q-13 in Hebrew is a brief version of the EDE-Q that includes bingeing and purging subscales and has satisfactory psychometric properties. Its use in clinical and research contexts is encouraged.
Highlights
The Eating Disorders Examination–Questionnaire (EDE-Q) has been in use for over quarter of a century [1] and has been translated into many languages, including Hebrew [2]
The EDE-Q-13 in Hebrew is a brief version of the EDE-Q that includes bingeing and purging subscales and has satisfactory psychometric properties
In this study we examined a 13-item version of the EDE-Q, consisting of a seven-item version shown to have good properties and six EDE-Q items assessing binge eating and purging
Summary
The EDE-Q has been in use for over quarter of a century [1] and has been translated into many languages, including Hebrew [2]. Grilo et al [8] administered the EDE-Q to a sample of undergraduate students in the United States, and found, using confirmatory factor analysis, a 3-factor solution: Dietary Restraint, Shape/Weight overvaluation, and Body Dissatisfaction. In their analyses, they found that a short seven-item form reproduced this hypothesized three-factor solution, but that it showed higher convergent validity than did the longer versions of the EDE-Q they considered. The seven items selected did not include any that measured bingeing or purging
