Abstract
BACKGROUND: Efficient assessment of eating disorders (ED) is indispensable for research and clinical practice in Mexico. One of the most commonly used questionnaires, the EDE-Q, has a self-applicable questionnaire format with 28 questions and four subscales drawn from the Eating Disorder Examination (EDE), a semistructured interview developed to evaluate the specific symptomatology of eating disorders. OBJECTIVE: Obtain the factorial structure and construct validity of the EDE-Q questionnaire in Mexican women. METHOD: The language in the EDE-Q was adapted. It was applied to university students (N = 330) and a sample of patients with ED (N = 165) from two ED outpatient treatment services. The anthropometric data of the participants was obtained. Internal consistency was explored using the Cronbach's Alpha coefficient and a confirmatory factor analysis was conducted by group. RESULTS: Cronbach's alpha was 0.9 for the full scale in all groups, while the reliability of each of the subscales fluctuated between 0.8 and 0.9. Confirmatory factor analysis showed that the fit of the seven-item model in three factors was better than that of the original 22-item one and that of the eight-item model for one factor. CONCLUSIONS: This study provides information supporting the seven-item and three-factor version, rather than the original or eight-item versions of the EDE-Q. In the future, the adapted version of the EDE-Q will make it possible to draw comparisons between Mexican samples in other socio-cultural contexts. Future research is required to continue refining the instruments to achieve more representative results from the general ED population.
