Individuals suffering from overweight or obesity frequently experience weight-based stigmatization. The widespread belief that weight is a matter of personal will and self-control results in various weight-based stereotypes (e.g., laziness, lack of self-discipline, or neglect).
Based on the modified version of the Weight Bias Internalization Scale (WBIS-M), a short form for the economic assessment of weight bias internalization in the general population was compiled and validated.
A three-item short form (WBIS-3) was derived based on data from a representative sample of the German population (n = 1,092). This new short form was validated in a second representative population sample (n = 2,513). Item characteristics and internal consistency were obtained. Measurement invariance was tested. Construct validity was established via the correlation with theoretically related constructs (depression, anxiety, eating behavior, discrimination, weight status). To establish scale validity, all analyses were performed for the whole sample as well as for the subsample of individuals with overweight. Age- and gender-specific population norms were provided.
The WBIS-3 exhibited excellent psychometric properties. Internal consistency was α = 0.92. Strong measurement invariance was confirmed regarding age, gender, discrimination, and weight status in both the whole sample as well as the overweight subsample.
The WBIS-3 constitutes a valid and economical tool for the assessment of weight bias internalization in epidemiological contexts. Measurement invariance allows for an unbiased comparison of means, correlation coefficients, and path coefficients within structural equation modeling across groups.
超重或肥胖的个体经常会经历基于体重的污名化。普遍认为体重是个人意志和自我控制的问题，导致了各种基于体重的刻板印象（例如，懒惰、缺乏自律或忽视）。
基于体重偏见内化量表（WBIS-M）的修改版本，编制并验证了一种用于评估一般人群体重偏见内化的经济评估的简短形式。
从德国代表性人群样本（n=1092）的数据中得出了一个三项目的简短形式（WBIS-3）。在第二个具有代表性的人群样本（n=2513）中验证了这个新的简短形式。获得了项目特征和内部一致性。测试了测量不变性。通过与理论相关的结构（抑郁、焦虑、饮食行为、歧视、体重状况）的相关性来确立构念效度。为了建立量表效度，对整个样本以及超重亚样本进行了所有分析。提供了年龄和性别特定的人口常模。
WBIS-3 具有出色的心理测量特性。内部一致性为α=0.92。在整个样本以及超重亚样本中，都确认了年龄、性别、歧视和体重状况方面的强测量不变性。
WBIS-3 是一种在流行病学背景下评估体重偏见内化的有效且经济的工具。测量不变性允许在结构方程建模中，在组内进行无偏的均值、相关系数和路径系数比较。
