Internalized weight stigma (IWS) has been linked with disordered eating behavior, both directly, and as a mediator of the relationship between experienced weight stigma and maladaptive coping. However, the construct of IWS is highly correlated with the related constructs of body image and global self-esteem, and the three constructs may better be represented by underlying trait self-judgment. This overlap is not generally accounted for in existing studies. The present study investigated the shared variance between self-esteem, body image, and IWS in an international sample of higher-weight individuals. Bifactor analysis confirmed that the intermediary role of IWS in the relationship between experienced stigma and self-reported eating behavior was largely accounted for by aspects of body image and global self-esteem. Greater conceptual clarity in the study of IWS is needed to understand the mechanisms via which societal weight stigma impacts on individuals' self-directed judgments and downstream health-related behaviors.
内化的体重耻辱感（IWS）与饮食失调行为有关，无论是直接相关，还是作为经历体重耻辱感和适应不良应对方式之间关系的中介因素。然而，IWS 这一概念与身体意象和整体自尊等相关概念高度相关，这三个概念可能更好地由潜在的特质自我判断来代表。现有研究通常没有考虑到这种重叠。本研究在一个国际高体重个体样本中调查了自尊、身体意象和 IWS 之间的共享方差。双因素分析证实，IWS 在经历的耻辱感与自我报告的饮食行为之间的中介作用在很大程度上被身体意象和整体自尊所解释。为了理解社会体重耻辱感对个体自我导向判断和下游健康相关行为的影响机制，需要在 IWS 的研究中进一步明确概念。
