内化普遍存在的体重偏见，通常针对超重和肥胖的个体，与增加的精神病理和生活质量受损共同发生。本研究试图在一个具有代表性的社区样本中建立最广泛使用的自我报告问卷——体重偏见内化量表（WBIS）的人口规范和心理测量特性。在一项针对德国人群的调查中，用WBIS和自我报告方法对N = 1158名超重和肥胖个体进行了评估，以进行收敛性验证。项目分析显示，除一个WBIS项目外，其余项目与项目总量均具有良好的相关性。删除此项目后，项目的同质性和内部一致性非常好。采用验证性因子分析证实了WBIS的单因素结构。趋同效度通过与抑郁和躯体症状测量的显著关联显示出来。WBIS有助于解释抑郁和躯体形式症状高于体重指数的差异。女性的WBIS得分高于男性，肥胖者高于超重者，受教育程度或收入较低的人高于受教育程度或收入较高的人。提供了特定性别的规范。结果表明，去除一个项目后，WBIS具有良好的心理测量性能。未来的研究需要进一步研究信度和效度指标，例如，重测信度、对变化的敏感性和预后效度。
Internalizing the pervasive weight bias commonly directed towards individuals with overweight and obesity, co-occurs with increased psychopathology and impaired quality of life. This study sought to establish population norms and psychometric properties of the most widely used self-report questionnaire, the Weight Bias Internalization Scale (WBIS), in a representative community sample. In a survey of the German population, N = 1158 individuals with overweight and obesity were assessed with the WBIS and self-report measures for convergent validation. Item analysis revealed favorable item-total correlation of all but one WBIS item. With this item removed, item homogeneity and internal consistency were excellent. The one-factor structure of the WBIS was confirmed using confirmatory factor analysis. Convergent validity was shown through significant associations with measures of depressive and somatoform symptoms. The WBIS contributed to the explanation of variance in depressive and somatoform symptoms over and above body mass index. Higher WBIS scores were found in women than in men, in individuals with obesity than in individuals with overweight, and in those with lower education or income than those with higher education or income. Sex-specific norms were provided. The results showed good psychometric properties of the WBIS after removal of one item. Future research is warranted on further indicators of reliability and validity, for example, retest reliability, sensitivity to change, and prognostic validity.
