目的：进食障碍检查问卷（ed - q）是一种评估进食障碍特定精神病理和关键行为的自我报告工具。本研究旨在确定进食障碍的流行程度，并在具有代表性的德国人口样本中提供ed - q的心理测量特性和规范。方法：共2520人（男性1166人，女性1354人）接受ed - q评估。结果：女性饮食失调精神病理发生率较高，多数关键行为发生率高于男性。男女精神病理学随年龄的增长而下降，男性在55-64岁达到高峰。总体而言，5.9%的女性和1.5%的男性表现出饮食失调。在女性中，饮食失调的患病率随着年龄的增长而下降，肥胖人群的患病率明显高于正常体重人群。心理测量分析显示有利的项目特征。ed - q综合评分的内部一致性女性为>= 80，男性为>= 70。部分重现了ed - q的因子结构。报告了特定性别和年龄的人口标准。讨论：本研究提供了ed - q在性别和年龄范围内的人口标准，展示了症状学上的人口差异，并揭示了令人满意的心理测量特性。对老年人饮食障碍的进一步研究是有必要的。
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% 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.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. Further research is warranted on eating disturbances in older adults.
