The Eating Attitude Test (EAT) and its language-simplified version for children (ChEAT) have been popular instruments for the assessment of eating attitudes among children, adolescents and young adult females.
Data collected from female adolescents using the ChEAT were analyzed to compare five previously proposed measurement models as well as a new model.
Confirmatory factor analysis (CFA) was used to directly compare models in terms of their goodness-of-fit indices and to determine which model best fits the overall data (N=737) as well as data from the youngest and oldest girls (N=200 each).
A newly proposed 14-item, 5-factor model provided the best fit to the overall data as well as data analyzed separately for the youngest and oldest girls. Furthermore, each of the newly proposed factor scores varied somewhat independently as a function of grade level, with body image concerns increasing most dramatically from grades 5 through 8. This newly proposed model is based on factors previously suggested by others, but not previously combined into a single measurement model.
Implications of the results for future research involving adolescent girls are discussed, especially research on developmental changes in eating attitudes and behaviors that may constitute risk factors for subsequent eating disorders.
《饮食态度测试》（EAT）及其儿童语言简化版（ChEAT）一直是评估儿童、青少年和年轻成年女性饮食态度的常用工具。
分析使用ChEAT从青少年女性收集的数据，以比较五个先前提出的测量模型以及一个新模型。
使用验证性因素分析（CFA）直接根据拟合优度指标比较模型，并确定哪个模型最适合总体数据（N = 737）以及最年轻和最年长女孩的数据（各N = 200）。
新提出的14项、5因素模型最适合总体数据以及分别为最年轻和最年长女孩分析的数据。此外，新提出的每个因素得分在一定程度上随年级水平独立变化，对身体形象的关注从5年级到8年级增加最为显著。这个新提出的模型基于其他人先前提出的因素，但以前没有组合成一个单一的测量模型。
讨论了结果对未来涉及青少年女孩研究的影响，特别是对可能构成后续饮食失调风险因素的饮食态度和行为发展变化的研究。
