The present paper reports on the construction and validation of a new scale for measuring eating disorders, the Eating Habits Questionnaire (EHQ), which is designed to assess not only existing disorders but also the likelihood of developing such disorders. The EHQ was initially validated on a large sample of university students, followed by further tests of reliability and validity amongst a number of both eating-disordered and normal comparison groups. Factor analysis of the initial item pool produced a 57-item, three-factor structure concerned with weight and dieting, restrained eating patterns, and overeating. Concurrent validation confirmed anticipated relationships with existing self-report scales, and the EHQ was found to be both internally consistent and stable over time. The new scale distinguished reliably between diagnosed eating-disordered patients and normal subjects, and results indicated that around 5% of undiagnosed female undergraduates scored in the same range as the patient population.
本文报告了一种用于测量饮食失调的新量表——饮食习惯问卷（EHQ）的构建与验证情况。该量表不仅旨在评估现有的饮食失调问题，还能评估出现此类失调的可能性。EHQ最初在大量大学生样本上进行了验证，随后在多个饮食失调组和正常对照组中进行了进一步的信效度测试。对初始项目库进行因子分析得出了一个由57个项目组成的三因素结构，涉及体重与节食、克制饮食模式和暴饮暴食。同时效度验证证实了该量表与现有自陈量表之间预期的关系，并且发现EHQ在内部一致性和随时间的稳定性方面表现良好。新量表能够可靠地区分已确诊的饮食失调患者和正常受试者，结果表明，约5%未被诊断出的本科女生得分与患者群体处于同一范围。
