Objective: The Eating Disorder Examination-Questionnaire (EDE-Q) is one of the most widely used self-report assessments of eating disorder symptoms. However, evidence indicates potential problems with its original factor structure and associated psychometric properties in a variety of populations, including gender minority populations. The aim of the current investigation was to explore several previously published EDE-Q factor structures and to examine internal consistency and measurement invariance of the best-fitting EDE-Q model in a large community sample of gender minority adults. Methods: Data were drawn from 1567 adults (337 transgender men, 180 transgender women, and 1050 gender-expansive individuals) who participated in The PRIDE Study, a large-scale longitudinal cohort study of sexual and gender minorities from the United States. A series of confirmatory factor analyses (CFAs) were conducted to explore the fit of eight proposed EDE-Q models; internal consistency (Cronbach's alphas, Omega coefficients) and measurement invariance (multi-group CFA) were subsequently evaluated. Results: A brief seven-item, three-factor (dietary restraint, shape/weight overvaluation, body dissatisfaction) model of the EDE-Q consistently evidenced the best fit across gender minority groups (transgender men, transgender women, gender-expansive individuals). The internal consistencies of the three subscales were adequate in all groups, and measurement invariance across the groups was supported. Discussion: Taken together, these findings support the use of the seven-item, three-factor version of the EDE-Q for assessing eating disorder symptomatology in gender minority populations. Future studies can confirm the current findings in focused examinations of the seven-item, three-factor EDE-Q in diverse gender minority samples across race, ethnicity, socioeconomic status, and age ranges. Public Significance Statement: Although transgender individuals have greater risk of developing an eating disorder, the factor structure of the Eating Disorder Examination-Questionnaire, one of the most widely used eating disorder assessment measures, has not been explored in transgender adults. We found that a seven-item model including three factors of dietary restraint, shape and weight overvaluation, and body dissatisfaction had the best fit among transgender and nonbinary adults.
