To examine the factor structure of the EDE-Q among a sample of adolescents.
A community-based sample of 917 adolescents (522 girls and 395 boys) aged 14-18 years completed the EDE-Q version 6.0 as part of a larger study. Participants were randomly assigned to one of two subsamples to enable separate analyses.
A confirmatory factor analysis on the original four factor model of the EDE-Q produced an inadmissible model with a poor fit. Exploratory factor analysis using principal axis factoring produced an alternative three factor model of the EDE-Q among adolescents. The Shape and Weight Concerns, Restriction and Preoccupation and Eating Concern subscales accounted for 65% of the total variance. Subscale and global scores were significantly higher for girls than for boys. A high proportion of both girls (53.6%) and boys (30.5%) reported participating in at least one key eating disordered behaviour during the previous 28 days.
The results of this study present three new subscales (Shape and Weight Concerns, Restriction and Preoccupation and Eating Concern) which are suggested for use in future research which uses the EDE-Q with community samples of adolescents.
在青少年样本中检验 EDE-Q 的因子结构。
本研究采用基于社区的样本，共 917 名 14-18 岁的青少年（522 名女生和 395 名男生）完成了 EDE-Q 版本 6.0，这是一项更大研究的一部分。参与者被随机分配到两个子样本中的一个，以便进行单独的分析。
对 EDE-Q 的原始四因子模型进行验证性因子分析，得出的模型不可接受，拟合度较差。使用主轴因子分析对 EDE-Q 进行探索性因子分析，得出了青少年 EDE-Q 的替代三因子模型。体型和体重担忧、限制和专注以及进食担忧分量表解释了总方差的 65%。女生的分量表和总分显著高于男生。在过去 28 天内，相当比例的女生（53.6%）和男生（30.5%）报告至少参与了一种关键的饮食障碍行为。
本研究的结果提出了三个新的分量表（体型和体重担忧、限制和专注以及进食担忧），建议在未来使用 EDE-Q 对青少年社区样本进行研究时使用。
