Abstract：
The present study translated and validated an Arabic version of the Three-Factor Eating Questionnaire-R18 (TFEQ-R18), which assesses eating behaviour traits among Arabic speakers in the three domains: cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). Three bilingual experts first translated the English questionnaire into Arabic, and the questionnaire\'s comprehension was tested among 298 Arabic speakers. Confirmatory factor analysis (CFA) tested the model fit and flagged four items in the questionnaire with low consistency. These items were modified, and the revised Arabic version of TFEQ-R18 was validated in a population of 513 individuals. Validity was evaluated using CFA and Pearson\'s correlation coefficients, internal consistency using Cronbach\'s α, and the reproducibility of the questionnaire was confirmed with Bland-Altman analysis and T-test. The construct validity of the Arabic TFEQ-R18 was evaluated by comparing the response score in the population based on gender, BMI and age group. CFA confirmed that the model fit is good and strongly agrees with the collected data. Except for item 15 in the CR domain, all questions showed moderate to high correlation within their respective domains. The Cronbach\'s α for UE, EE, and CR domains recorded was 0.778, 0.784 and 0.588, respectively. Item 15 had the lowest consistency in the Arabic-TFEQ-R18, and Cronbach\'s α increased to 0.608 with its removal. There was no significant difference between the first and second attempts of the Arabic TFEQ-R18, indicating good test-retest reliability. Moreover, UE and EE were positively correlated to the BMI of the participants (r = 0.159, p = 0·000; r = 0.158, p = 0·000, respectively). The study concludes that the Arabic TFEQ is a valid and reliable tool for studying the three psychometric domains of UE, EE and CR among Arabic speakers.
摘要：
本研究翻译并验证了阿拉伯语版本的三因素饮食问卷-R18（TFEQ-R18），它评估了阿拉伯语使用者在三个领域的饮食行为特征：认知约束(CR)，不受控制的饮食（UE），情绪化饮食（EE）。三位双语专家首先将英文问卷翻译成阿拉伯文，问卷的理解在298名阿拉伯语使用者中进行了测试。验证性因素分析（CFA）检验了模型的拟合度，并在问卷中标记了四个项目，一致性较低。这些项目已修改，修订后的TFEQ-R18阿拉伯文版本在513人的人群中得到验证。使用CFA和Pearson相关系数评估有效性，使用克朗巴赫α的内部一致性，通过Bland-Altman分析和T检验证实了问卷的可重复性。阿拉伯TFEQ-R18的结构效度通过比较基于性别的人群中的反应得分来评估，BMI和年龄组。CFA确认模型拟合良好，并且与收集的数据非常吻合。除CR域中的第15项外，所有问题在各自领域内都表现出中等到高度的相关性.克伦巴赫的α为UE，EE,记录的CR域分别为0.778、0.784和0.588。项目15在阿拉伯-TFEQ-R18中的稠度最低，而Cronbach的α在去除后增加到0.608。阿拉伯TFEQ-R18的第一次和第二次尝试之间没有显着差异，表明良好的重测可靠性。此外，UE和EE与参与者的BMI呈正相关（分别为r=0.159，p=0·000；r=0.158，p=0·000）。该研究得出结论，阿拉伯语TFEQ是研究UE的三个心理测量领域的有效和可靠的工具，讲阿拉伯语的人中的EE和CR。
