OBJECTIVES
To analyze the dimensionality of three versions of the Eating Disorder Inventory (EDI) in adolescent girls.
METHOD
The sample comprised 738 participants. The Spanish adaptation of the EDI-2 was used. The EDI-2 contains the 64 items of EDI and has the same items as EDI-3. The dimensional structures hypothesized by Garner for the three EDI versions were assessed via a series of Confirmatory Factor Analyses (CFAs).
RESULTS
The CFA did not confirm Garner's proposed structure in any of the three versions. Consequently it was decided to perform Exploratory Factor Analyses (EFA) of the EDI-2 and the EDI-3 to try to identify the underlying structure. The best theoretical and empirical fit was provided by a 7-factor structure.
DISCUSSION
This article presents a shortened version of the EDI-2 which may prove more suitable for use with adolescent girls in the general population than the original questionnaire. Certain practical suggestions for optimizing the use of the different versions of the EDI are also presented.
目的
分析青少年女性中三种 Eating Disorder Inventory（饮食障碍问卷）版本的维度结构。
方法
样本包括 738 名参与者。使用了 Eating Disorder Inventory-2（饮食障碍问卷 2 版）的西班牙语版。Eating Disorder Inventory-2 包含 Eating Disorder Inventory-3 的 64 个项目。通过一系列验证性因子分析（Confirmatory Factor Analyses，CFA）评估了 Garner 为这三个 Eating Disorder Inventory 版本提出的维度结构假设。
结果
CFA 没有在任何一个版本中证实 Garner 提出的结构。因此，决定对 Eating Disorder Inventory-2 和 Eating Disorder Inventory-3 进行探索性因子分析（Exploratory Factor Analyses，EFA），以尝试确定潜在结构。7 因素结构提供了最佳的理论和经验拟合。
讨论
本文提出了 Eating Disorder Inventory-2 的简化版，与原始问卷相比，对于一般人群中的青少年女性来说可能更适合使用。还提出了优化使用不同版本 Eating Disorder Inventory 的一些实际建议。
