目的：评估三因素饮食问卷（TFEQ）在肥胖男性和女性中的结构效度。对象：瑞典肥胖受试者（SOS）研究中共有 4377 名中年肥胖受试者。方法：将总样本随机分为两个数据子集，对每个样本分别进行心理测量。进行多特征/多项目分析来测试尺度假设，并使用因子分析来测试因子结构。心理健康测量（MACL、HAD）用于测试基于标准的效度。结果：认知约束因素得到一致再现，量表分析显示出较强的项目量表判别效度，而项目量表收敛效度不令人满意。去抑制量表的内部结构较弱。大多数抑制解除和饥饿项目都归为一个标记为“不受控制的饮食”的全球因素。还确定了包含情绪饮食项目的第三个集群。获得的三因子结构按性别、年龄和 BMI 进行交叉验证并在亚组之间复制。结论：原始 TFEQ 因子结构没有被复制。构建了一个经过修订的简短工具，包含 18 项，代表认知约束、不受控制的饮食和情绪饮食的派生因素。最有效的项目用于提高量表的收敛效度和判别效度。
OBJECTIVE: To evaluate the construct validity of the Three-Factor Eating Questionnaire (TFEQ) in obese men and women.SUBJECTS: A total of 4377 middle-aged, obese subjects in the Swedish Obese Subjects (SOS) study.METHODS: The total sample was randomly split into two data subsets and psychometric testing was performed separately in each sample. Multitrait/multi-item analysis was conducted to test scaling assumptions and factor analysis was used to test the factor structure. Measures of mental well-being (MACL, HAD) were used for testing criterion-based validity.RESULTS: The Cognitive Restraint factor was consistently reproduced and scaling analysis demonstrated strong item-scale discriminant validity, while the item-scale convergent validity was unsatisfactory. The internal structure of the Disinhibition scale was weak. Most Disinhibition and Hunger items grouped in one global factor labeled Uncontrolled Eating. A third cluster containing items on Emotional Eating was also identified. The obtained three-factor structure was cross-validated and replicated across subgroups by gender, age and BMI.CONCLUSION: The original TFEQ factor structure was not replicated. A short, revised 18-item instrument was constructed, representing the derived factors of Cognitive Restraint, Uncontrolled Eating and Emotional Eating. The most efficient items were used to boost both the convergent and discriminant validity of the scales.
