The Three-Factor Eating Questionnaire (TFEQ) is one of the most widely used instruments to study different eating behaviors. It measures three types of eating behaviors namely: cognitive restraint, uncontrolled eating and emotional eating. The present study aims to evaluate the factor structure and reliability of the Portuguese version of the TFEQ-R21, using a confirmatory factor analysis (CFA). The sample includes 468 participants from the general population, with ages ranging from 18 to 60 years. Results from the CFA confirmed the TFEQ-R21 three-factor structure and the model revealed an acceptable fit to the data (χ(186) = 443.211, p < 0.001; χ/df = 2.329; CFI = 0.933; TLI = 0.925; RMSEA = 0.054; SMRS = 0.053). Multi-group analysis results support strong measurement invariance across genders. Furthermore, all three dimensions presented adequate psychometric properties. Overall, results support that the Portuguese version of the TFEQ-R21 is a useful, reliable and robust instrument to assess relevant eating behaviors.Level of evidence V, descriptive studies.
《三因素饮食问卷（TFEQ）》是研究不同饮食行为最常用的工具之一。它测量了三种饮食行为，即认知约束、失控性进食和情绪性进食。本研究旨在使用验证性因素分析（CFA）评估 TFEQ-R21 的葡萄牙语版本的因子结构和可靠性。样本包括来自普通人群的 468 名参与者，年龄在 18 至 60 岁之间。CFA 的结果证实了 TFEQ-R21 的三因子结构，该模型显示出与数据的可接受拟合（χ（186）= 443.211，p < 0.001；χ/df = 2.329；CFI = 0.933；TLI = 0.925；RMSEA = 0.054；SMRS = 0.053）。多组分析结果支持跨性别具有很强的测量不变性。此外，所有三个维度都具有良好的心理测量特性。总体而言，结果支持 TFEQ-R21 的葡萄牙语版本是评估相关饮食行为的有用、可靠和强大的工具。证据水平 V，描述性研究。
