Adult eating behavior questionnaire (AEBQ) is an age upward extension tool that measures appetite traits in individuals. This instrument was developed by Hunot in 2016. The present study aimed to determine the psychometric properties of the Persian version of AEBQ in adults with epilepsy.
The current research is a cross-sectional study conducted in 2019 in Iran. 700 adults with epilepsy completed the 35-item AEBQ. Qualitative face validity, qualitative content and structure validity (exploratory factor analysis [EFA], N=400, and confirmatory factor analysis [CFA], N=300) appetitive traits were evaluated. Reliability was also measured using Cronbach's alpha, Construct reliability (CR), and Intra-Class Correlation (ICC). The SPSS 26-AMOS24 software was employed to analyze the data with a significance level of 0.05.
The EFA and CFA results comprised eight factors, namely enjoyment of food, emotional over-eating, food responsiveness, hunger, satiety responsiveness, emotional under-eating, food fussiness, and eating slowly. Indices of root mean square error of approximation=0.068, parsimonious normed fit index=0.644, parsimonious comparative fit index=0.671, adjusted goodness of fit index=0.618, goodness of fit index=0.911, and Chi square degree-of-freedom ratio (normalized Chi square CMIN/DF=2.842) confirmed the fitness of the final model. Convergent and divergent validity was acceptable for all the factors. The results revealed that the internal stability>0.8 and CR>0.7 of the eight extracted AEBQ structures are confirmed. The ICC was 0.899 (95% CI: 0.878-0.917; P<0.001). The results also showed that AEBQ has acceptable convergent and divergent validity.
The eight-factor structure of AEBQ can measure eating behavior traits and is of good validity and reliability for assessing the eating behavior of Iranian adults with epilepsy.
成人饮食行为问卷（AEBQ）是一种测量个体食欲特征的年龄扩展工具，由 Hunot 于 2016 年开发。本研究旨在确定成人癫痫患者 AEBQ 波斯语版本的心理测量特性。
本研究为 2019 年在伊朗进行的横断面研究。700 名成人癫痫患者完成了 35 项 AEBQ。通过定性表面有效性、定性内容和结构有效性（探索性因子分析 [EFA]，N=400，验证性因子分析 [CFA]，N=300）评估食欲特征。使用 Cronbach's alpha、结构可靠性（CR）和组内相关系数（ICC）来衡量可靠性。使用 SPSS 26-AMOS24 软件进行数据分析，显著性水平为 0.05。
EFA 和 CFA 结果包括 8 个因素，即享受食物、情绪性暴食、食物反应性、饥饿、饱腹感反应性、情绪性少食、食物挑剔和进食缓慢。近似均方根误差指数=0.068，简约规范拟合指数=0.644，简约比较拟合指数=0.671，调整拟合优度指数=0.618，拟合优度指数=0.911，卡方自由度比（标准化卡方 CMIN/DF=2.842）证实了最终模型的适应性。所有因素的收敛和发散效度均可接受。结果表明，8 个提取的 AEBQ 结构的内部稳定性>0.8 和 CR>0.7 得到确认。ICC 为 0.899（95%CI：0.878-0.917；P<0.001）。结果还表明，AEBQ 具有可接受的收敛和发散效度。
AEBQ 的 8 因素结构可以测量饮食行为特征，对于评估伊朗成年癫痫患者的饮食行为具有良好的效度和信度。
