Assessment of disordered eating has uncertain validity across culturally diverse populations. This study evaluated Eating Disorder Examination Questionnaire (EDE-Q) performance in an ethnic Fijian study population.
The EDE-Q was translated, adapted, and administered to school-going Fijian adolescent females (N = 523). A subsample (n = 81) completed it again within approximately 1 week. We assessed feasibility, internal consistency, and test-retest reliability; evaluated construct validity through factor analysis and correlation with similar constructs; and examined the marginal utility of an additional question on traditional purgative use.
Internal consistency reliability was adequate for the global scale and subscales (Cronbach's alpha = 0.66-0.91); retest reliability was adequate for both the languages (range of ICCs, 0.50-0.79, and of kappas, 0.46-0.81, excluding purging items). Construct validity was supported by significant correlations with measures of similar constructs. Factor analysis confirms multiple dimensions of eating disorder symptoms but suggests possible culture-specific variation in this population. The majority of respondents endorsing traditional purgative use (58%) did not endorse conventional EDE-Q items assessing purging.
The EDE-Q is a valid measure of eating disorder pathology for ethnic Fijian adolescent females and measures a unitary underlying construct.
在文化多元化的人群中，饮食失调的评估具有不确定的有效性。本研究评估了在斐济族群研究人群中使用饮食失调检查问卷（EDE-Q）的表现。
对在校的斐济青春期女性（N=523）进行 EDE-Q 的翻译、改编和实施。一个亚组（n=81）在大约 1 周内再次完成该问卷。我们评估了可行性、内部一致性和重测信度；通过因子分析和与相似结构的相关性来评估结构效度；并考察了关于传统泻药使用的额外问题的边际效用。
全球量表和分量表的内部一致性信度适中（克朗巴赫的 α 值为 0.66-0.91）；两种语言的重测信度均适中（ICC 的范围为 0.50-0.79，kappa 的范围为 0.46-0.81，不包括泻剂项目）。与相似结构的测量指标的显著相关性支持了结构效度。因子分析证实了饮食障碍症状的多个维度，但表明该人群可能存在特定文化的变异。大多数使用传统泻药的受访者（58%）没有认可评估泻药的传统 EDE-Q 项目。
EDE-Q 是评估斐济族裔青春期女性饮食障碍病理的有效工具，测量的是一个单一的潜在结构。
