The increasing prevalence of Eating Disorders over the last decades generates a growing interest of researchers and health care providers for their early detection through suitable questionnaires. The aim of the present study is to examine the reliability of the Greek version of EDE-Q 6.0 among secondary school adolescents. EDE-Q is a widely used self-report questionnaire that assesses the specific psychopathology of eating disorders. Its 6.0th version consists of 28 items. It yields two types of data: (a) four subscale scores (Restraint, Eating Concern, Shape Concern and Weight Concern) as well as a global score which is the average of the four subscale scores and (b) frequency data on key eating and compensatory behaviors (e.g. binge eating episodes, self-induced vomiting, excessive exercise). The sample comprises 257 secondary school students (133 girls and 124 boys) residents of north Evros-Greece, aged 16.1±1.4 years. The students completed the EDE-Q twice within a median interval of 34 days. In addition, their demographic data were collected and their weight and height were measured. The reliability of the EDE-Q was assessed by means of: (a) its internal consistency which was tested by Cronbach's alpha coefficient for each of the EDE-Q subscales as well as for the global score at both data collection times and (b) its test-retest reliability which was estimated by calculating: (1) intraclass correlation coefficients (ICCs) and Pearson's correlation coefficients (PCCs) for continuous variables (subscales and global score) and (2) Kendal's tau b coefficients for categorical variables (frequency of behavioral features). Cronbach's alphas indicating internal consistency of EDE-Q ranged from 0.71 to 0.91. ICCs and PCCs indicating the test-retest reliability of each subscale and the global score of the questionnaire ranged from 0.55 to 0.70 and from 0.58 to 0.73 respectively. Kendal tau b coefficients indicating the test-retest reliability of items assessing behavioral features ranged from 0.22 to 0.57. All the above correlations that concern the test-retest reliability of the EDE-Q were statistically significant at the 0.001 level. The Greek version of EDE-Q 6.0, standardized in a sample of secondary school students, presents adequate test-retest reliability and internal consistency as well.
在过去几十年中，饮食失调症的患病率不断上升，这使得研究人员和医疗保健提供者越来越有兴趣通过合适的问卷对其进行早期检测。本研究的目的是检验EDE-Q 6.0希腊语版本在中学生中的信度。EDE-Q是一种广泛使用的自我报告问卷，用于评估饮食失调症的特定精神病理学。其6.0版本由28个项目组成。它产生两种类型的数据：（a）四个子量表得分（克制、饮食关注、体型关注和体重关注）以及一个全局得分，该全局得分是四个子量表得分的平均值；（b）关键饮食和代偿行为的频率数据（例如暴饮暴食发作、自我催吐、过度运动）。样本包括257名希腊北部埃夫罗斯地区的中学生（133名女生和124名男生），年龄为16.1±1.4岁。学生们在34天的中位间隔内完成了两次EDE-Q问卷。此外，收集了他们的人口统计学数据，并测量了他们的体重和身高。EDE-Q的信度通过以下方式进行评估：（a）其内部一致性，通过在两次数据收集时对EDE-Q每个子量表以及全局得分计算克朗巴哈α系数来检验；（b）其重测信度，通过计算来估计：（1）连续变量（子量表和全局得分）的组内相关系数（ICC）和皮尔逊相关系数（PCC），以及（2）分类变量（行为特征频率）的肯德尔tau b系数。表明EDE-Q内部一致性的克朗巴哈α系数范围为0.71至0.91。表明问卷每个子量表和全局得分重测信度的ICC和PCC分别范围为0.55至0.70和0.58至0.73。表明评估行为特征项目重测信度的肯德尔tau b系数范围为0.22至0.57。所有上述与EDE-Q重测信度相关的相关性在0.001水平上均具有统计学意义。在中学生样本中标准化的EDE-Q 6.0希腊语版本也具有足够的重测信度和内部一致性。
