The Dutch Eating Behavior Questionnaire is an internationally widely used instrument assessing different eating styles that may contribute to weight gain and overweight: emotional eating, external eating, and restraint. This study aimed to evaluate the psychometric properties of the 30-item German version of the DEBQ including its measurement invariance across gender, age, and BMI-status in a representative German population sample. Furthermore, we examined the distribution of eating styles in the general population and provide population-based norms for DEBQ scales. A representative sample of the German general population (N = 2513, age ≥ 14 years) was assessed with the German version of the DEBQ along with information on sociodemographic characteristics and body weight and height. The German version of the DEQB demonstrates good item characteristics and reliability (restraint: α = .92, emotional eating: α = .94, external eating: α = .89). The 3-factor structure of the DEBQ could be replicated in exploratory and confirmatory factor analyses and results of multi-group confirmatory factor analyses supported its metric and scalar measurement invariance across gender, age, and BMI-status. External eating was the most prevalent eating style in the German general population. Women scored higher on emotional and restrained eating scales than men, and overweight individuals scored higher in all three eating styles compared to normal weight individuals. Small differences across age were found for external eating. Norms were provided according to gender, age, and BMI-status. Our findings suggest that the German version of the DEBQ has good reliability and construct validity, and is suitable to reliably measure eating styles across age, gender, and BMI-status. Furthermore, the results demonstrate a considerable variation of eating styles across gender and BMI-status.
荷兰饮食行为问卷是一种在国际上广泛使用的工具，用于评估可能导致体重增加和超重的不同饮食方式：情绪化饮食、外部饮食和克制饮食。本研究旨在评估30项德文版DEBQ的心理测量特性，包括其在德国代表性人群样本中跨性别、年龄和BMI状态的测量不变性。此外，我们研究了一般人群中饮食方式的分布情况，并提供了基于人群的DEBQ量表规范。对德国一般人群的代表性样本（N = 2513，年龄≥14岁）进行了德文版DEBQ评估，并收集了社会人口学特征以及体重和身高信息。德文版DEQB显示出良好的项目特征和信度（克制饮食：α = 0.92，情绪化饮食：α = 0.94，外部饮食：α = 0.89）。DEBQ的三因素结构在探索性和验证性因素分析中均可重复，多组验证性因素分析结果支持其在性别、年龄和BMI状态方面的度量和标量测量不变性。外部饮食是德国一般人群中最普遍的饮食方式。女性在情绪化饮食和克制饮食量表上的得分高于男性，超重个体在所有三种饮食方式上的得分均高于正常体重个体。在外部饮食方面发现了年龄之间的细微差异。根据性别、年龄和BMI状态提供了规范。我们的研究结果表明，德文版DEBQ具有良好的信度和结构效度，适用于可靠地测量不同年龄、性别和BMI状态的饮食方式。此外，结果表明不同性别和BMI状态的饮食方式存在相当大的差异。
