Extant research suggests that disordered eating is common in college women and is associated with decreased quality of life. The Eating Disorder Quality of Life Scale (EDQLS) examines impairment to disordered eating-related quality of life, but has not been validated in college women. Accordingly, the purpose of this study was to examine the reliability, validity, and factor structure of the EDQLS in a diverse sample of 971 college women.
Students from a large United States university completed questionnaires examining disordered eating and the EDQLS online.
The EDQLS demonstrated excellent internal consistency and good convergent validity with the Eating Disorder Examination Questionnaire (EDEQ). Contrary to the original 12-domain design of the EDQLS, principal component analyses suggested five factors that mapped onto the following constructs: (1) Positive Emotionality; (2) Body/Weight Dissatisfaction; (3) Disordered Eating Behaviors; (4) Negative Emotionality; and (5) Social Engagement. However, 15 of the 40 items loaded onto multiple factors.
Total scores on the EDQLS are reliable and valid when used with diverse samples of college women, but some revisions are needed to create subscales than can justifiably be used in clinical practice.
现有研究表明，饮食失调在大学生女性中很常见，并且与生活质量下降有关。饮食失调生活质量量表（EDQLS）检查与饮食失调相关的生活质量受损，但尚未在大学生女性中得到验证。因此，本研究的目的是在一个由 971 名大学生女性组成的多样化样本中，检验 EDQLS 的信度、效度和因子结构。
来自美国一所大型大学的学生在线完成了关于饮食失调和 EDQLS 的问卷。
EDQLS 表现出极好的内部一致性和与饮食失调检查问卷（EDEQ）的良好收敛效度。与 EDQLS 的原始 12 个领域设计相反，主成分分析表明有五个因素映射到以下结构：（1）积极情绪；（2）身体/体重不满；（3）饮食失调行为；（4）消极情绪；和（5）社会参与。然而，40 个项目中的 15 个加载到多个因素上。
EDQLS 的总分在使用具有多样性的大学生女性样本时是可靠和有效的，但需要进行一些修订，以创建可以在临床实践中合理使用的子量表。
