The Self-Regulation of Eating Behavior Questionnaire (SREBQ) is an economical way of assessing an individual's self-regulatory abilities regarding eating behavior. Such scales are needed in the German population; therefore, the purpose of the present study was the translation and validation of a German version of the SREBQ. First, we conducted a pilot study (Study 1; = 371) after the translation procedure. Second, we assessed the final scale in a representative sample of the German population (Sample 2; = 2,483) and its underlying factor structure. Further, we tested for measurement invariance and evaluated the SREBQ's associations with related scales to explore convergent and discriminant validity. Finally, we considered differences in SREBQ based on sociodemographic variables and provided derived reference scores (norm values). Factor analysis revealed deficiencies in the original model. Thus, we shortened the scale based on statistical considerations and the adapted version showed improved fit in Confirmatory Factor Analysis and reliability. We also found evidence for partial strict invariance, which means the measure is equivalent for the tested groups of age and gender. Item and scale psychometric properties of the shortened version were satisfactory. In terms of diagnostic validity, it was shown that individuals with higher body mass index (kg/m) have worse self-regulation of eating behavior than those with lower. In sum, the SREBQ evidenced good validity and reliability and is suitable for application in medical, psychological, and nutritional research.
饮食行为自我调节问卷（SREBQ）是评估个体饮食行为自我调节能力的一种经济方式。德国人群需要这样的量表；因此，本研究的目的是对SREBQ的德文版进行翻译和验证。首先，在翻译程序之后，我们进行了一项预试验研究（研究1；n = 371）。其次，我们在德国人群的一个代表性样本（样本2；n = 2483）中评估了最终量表及其潜在的因子结构。此外，我们测试了测量不变性，并评估了SREBQ与相关量表的关联，以探索聚合效度和区分效度。最后，我们考虑了基于社会人口统计学变量的SREBQ差异，并提供了导出的参考分数（常模值）。因子分析揭示了原始模型存在缺陷。因此，我们基于统计考量缩短了量表，改编后的版本在验证性因子分析中显示出更好的拟合度和信度。我们还发现了部分严格不变性的证据，这意味着该测量对于所测试的年龄和性别组是等效的。缩短版的项目和量表心理测量特性令人满意。在诊断效度方面，结果表明，体重指数（kg/m）较高的个体饮食行为自我调节能力比体重指数较低的个体更差。总之，SREBQ具有良好的效度和信度，适用于医学、心理学和营养学研究。
