The Three-Factor Eating Questionnaire Reduced (TFEQ-R18) is one of the most widely used instruments for assessing eating behavior worldwide. The present study aimed at confirming the reliability and validity of the Persian version of TFEQ-R18 among overweight and obese females in Iran. In the present study, 168 overweight and obese females consented to participate. We estimated the anthropometric indices and asked the participants to complete the TFEQ-R18. Beck Depression Inventory (BDI), Spielberger Anxiety Scale, Appetite Visual Analogue Rating Scale, Food Craving Questionnaire (FCQ), Compulsive Eating Scale (CES), and Restraint Eating Visual Analogue Rating Scale were performed simultaneously to assess concurrent validity. Two weeks later, TFEQ-R18 was repeated for 126 participants to assess test-retest reliability. Moreover, we reported the internal consistency and factor analysis of this questionnaire. Using the results of the reliability analysis and exploratory factor analysis of the principal component by varimax rotation, we extracted 3 factors: hunger, cognitive restraint, and emotional eating. After removing the Items 16 and 18, the Cronbach's alpha was increased to 0.73 (The Cronbach's alpha of the factors was 0.84, 0.64, and 0.7, respectively). The results of the Pearson correlation revealed a consistency of 0.87 between the test and retest administrations (p = 0.001). Significant positive correlations were observed between TFEQ-R18 and BDI, Spielberger Anxiety Scale, FCQ, CES, appetite, body weight, fat percentage, and calorie intake. Moreover, a negative correlation was observed in Restraint Eating Visual Analogue Rating Scale and muscle percentage This study aimed at presenting preliminary support for the reliability and validity of the Persian version of TFEQ-R18 and its psychometric characteristics. This instrument may be helpful in clinical practice and research studies of obesity, appetite, and eating behavior.
简版三因素饮食问卷（TFEQ-R18）是全球范围内评估饮食行为最广泛使用的工具之一。本研究旨在证实伊朗超重和肥胖女性中TFEQ-R18波斯语版本的信效度。在本研究中，168名超重和肥胖女性同意参与。我们评估了人体测量指标，并要求参与者完成TFEQ-R18。同时进行贝克抑郁量表（BDI）、斯皮尔伯格焦虑量表、食欲视觉模拟评分量表、食物渴望问卷（FCQ）、强迫进食量表（CES）和节食视觉模拟评分量表以评估同时效度。两周后，对126名参与者重复进行TFEQ-R18以评估重测信度。此外，我们报告了该问卷的内部一致性和因素分析。利用可靠性分析结果和通过方差最大化旋转的主成分探索性因素分析，我们提取了3个因素：饥饿、认知抑制和情绪化进食。去除第16项和第18项后，克朗巴哈系数提高到0.73（各因素的克朗巴哈系数分别为0.84、0.64和0.7）。皮尔逊相关性结果显示测试和重测之间的一致性为0.87（p = 0.001）。在TFEQ-R18与BDI、斯皮尔伯格焦虑量表、FCQ、CES、食欲、体重、脂肪百分比和卡路里摄入量之间观察到显著正相关。此外，在节食视觉模拟评分量表与肌肉百分比之间观察到负相关。本研究旨在为TFEQ-R18波斯语版本的信效度及其心理测量特征提供初步支持。该工具可能有助于肥胖、食欲和饮食行为的临床实践和研究。
