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.
A total of 2520 individuals (1166 men, 1354 women) were assessed with the EDE-Q.
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% of the women and 1.5% of the men revealed eating disturbances. The prevalence of eating disturbances decreased with age in women and was significantly higher in obese than in normal-weight individuals. Psychometric analyses showed favorable item characteristics. Internal consistencies of EDE-Q composite scores were ≥.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.
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. Further research is warranted on eating disturbances in older adults.
饮食障碍问卷（EDE-Q）是一种自我报告工具，用于评估饮食障碍的特定精神病理学和关键行为。本研究旨在确定德国代表性人群中饮食障碍的患病率，并提供 EDE-Q 的心理测量学特征和常模。
共有 2520 人（男性 1166 人，女性 1354 人）接受了 EDE-Q 的评估。
女性的饮食障碍精神病理学水平更高，大多数关键行为更为普遍。精神病理学在两性中均随着年龄≥65 岁而下降，并在男性中 55-64 岁达到峰值。总体而言，5.9%的女性和 1.5%的男性存在饮食障碍。女性的饮食障碍患病率随年龄增长而下降，肥胖者明显高于正常体重者。心理测量学分析显示，项目特征良好。EDE-Q 综合评分的内部一致性在女性中为≥.80，在男性中为≥.70。EDE-Q 的因子结构部分再现。报告了性别和年龄特异性的人群常模。
本研究提供了两性和整个年龄范围的 EDE-Q 人群常模，展示了症状学的人口统计学差异，并显示出令人满意的心理测量学特性。需要进一步研究老年人的饮食障碍。
