How Frequent Are Eating Disturbances in the Population? Norms of the Eating Disorder Examination-Questionnaire

Abstract

Objective: The Eating Disorder Examination-Questionnaire (EDE-Q) is a self-report instrument assessing the specific psychopathology and key behaviors of eating disorders. This study sought to determine the prevalence of eating disturbances, and to provide psychometric properties and norms of the EDE-Q, in a representative German population sample. Methods: A total of 2520 individuals (1166 men, 1354 women) were assessed with the EDE-Q. Results: Eating disorder psychopathology was higher and most key behaviors were more prevalent in women than in men. Psychopathology declined with age $65 in both sexes, and showed a peak at age 55–64 in men. Overall, 5.9$.80 for women and $.70 for men. The factor structure of the EDE-Q was partially reproduced. Sex- and age-specific population norms are reported. Discussion: This study provides population norms of the EDE-Q for both sexes and across the age range, demonstrates demographic variations in symptomatology, and reveals satisfactory psychometric properties.
