The first aim of the current study was to establish general population norms for the Portuguese version of the Eating Disorder Examination Questionnaire (EDE-Q) in a large community sample of female adolescents and young women, as well, for a diverse Eating Disorder (ED) clinical sample, and for women with obesity without an ED. A second aim of the study was to assess the discriminant validity of the EDE-Q and providing cut-off scores for the total scale and subscales.
A sample of female adolescents and young women (N = 4091) from the general population, 416 women who met diagnostic criteria for an ED and 138 women seeking obesity treatment completed the EDE-Q.
Norms for the EDE-Q global subscale were provided. Within the community sample, norms were provided for both high school and college samples. Receiver operating characteristic analysis showed that the EDE-Q total score accurately discriminate between participants with and without an ED. Current norm contributes to the clinical utility of the EDE-Q, providing both a cut-off score and reliable change index. Results showed that the EDE-Q is a reliable instrument, but the theorized four subscales structure was not supported by an explorative factor analysis.
Results will help both researchers and clinicians interpreting the EDE-Q scores and to establish comparison with data produced in different countries.
本研究的首要目的是为葡萄牙版饮食失调检查问卷（EDE-Q）建立一般人群的常模，该问卷适用于大量女性青少年和年轻女性的社区样本，以及不同饮食失调（ED）临床样本和肥胖但无 ED 的女性。研究的第二个目的是评估 EDE-Q 的判别效度，并提供总量表和分量表的截断分数。
本研究的样本包括来自一般人群的女性青少年和年轻女性（N=4091）、符合 ED 诊断标准的 416 名女性和寻求肥胖治疗的 138 名女性，她们均完成了 EDE-Q 问卷。
提供了 EDE-Q 全球分量表的常模。在社区样本中，为高中和大学样本提供了常模。受试者工作特征曲线分析显示，EDE-Q 总分能够准确区分有和无 ED 的参与者。目前的常模有助于 EDE-Q 的临床应用，提供了截断分数和可靠变化指数。结果表明，EDE-Q 是一个可靠的工具，但探索性因素分析不支持理论上的四个分量表结构。
研究结果将有助于研究人员和临床医生解释 EDE-Q 评分，并与不同国家产生的数据进行比较。
