OBJECTIVE
The purpose of this investigation was to evaluate the factor structure and the internal consistency of the Eating Disorder Examination-Questionnaire (EDE-Q).
METHOD
The EDE-Q was administered to 203 women with bulimic symptoms, who were recruited from five Midwestern communities.
RESULTS
Acceptable levels of internal consistency were observed for the EDE-Q total score (alpha = .90) and subscales: Restraint (alpha = .70), Eating Concern (alpha = 0.73), Shape Concern (alpha = 0.83) and Weight Concern (alpha = 0.72). Exploratory factor loadings using Principal Axis Analysis supported the Eating Concern and Restraint subscales. Most of the Shape Concern and Weight Concern items loaded on one factor, with the exception of the items focusing on the importance of weight and shape in self-evaluation and preoccupation with shape and weight.
CONCLUSION
The results of this study provide support for the internal consistency of the EDE-Q and indicate a need for further examination of the factor structure of this instrument.
目的
本研究旨在评估饮食失调检查问卷（EDE-Q）的因子结构和内部一致性。
方法
EDE-Q被施用于203名有贪食症状的女性，她们是从五个中西部社区招募而来的。
结果
EDE-Q总分（α = 0.90）及分量表的内部一致性水平达到可接受程度：克制（α = 0.70）、饮食关注（α = 0.73）、体型关注（α = 0.83）和体重关注（α = 0.72）。使用主轴分析的探索性因子载荷支持了饮食关注和克制分量表。除了关注体重和体型在自我评价中的重要性以及对体型和体重的过度关注的项目外，大多数体型关注和体重关注项目都加载在一个因子上。
结论
本研究结果支持EDE-Q的内部一致性，并表明需要进一步检查该工具的因子结构。
