The present study aimed to expand weight stigma theoretical models by accounting for central tenets of prominent eating disorder (ED) theories and increasing the generalizability of existing models for individuals across the weight spectrum. College students (Sample 1: N = 1228; Sample 2: N = 1368) completed online surveys assessing stigma and ED symptoms. In each sample, separately, multi-group path analyses tested whether body mass index (BMI) classification (underweight/average weight, overweight, obese) moderated a model wherein weight stigma experiences were sequentially associated with weight bias internalization, body dissatisfaction, and five ED symptoms: binge eating, purging, restricting, excessive exercise, muscle building behaviors. Results supported the assessed model overall and for individuals in each BMI class, separately. Although patterns of associations differed for individuals with different BMIs, these variations were limited. The present findings suggest that the adverse impact of weight stigma on distinct ED symptoms is not limited to individuals with elevated BMIs and that these associations are generally explained by the same mechanisms. Weight stigma interventions that focus on decreasing weight bias internalization and body dissatisfaction are recommended for individuals across the weight spectrum. Further examination of associations between weight stigma and multiple ED symptoms, beyond disinhibited eating, is supported.
本研究旨在通过考虑突出的饮食失调（ED）理论的核心原则并提高现有模型对不同体重范围个体的通用性，来扩展体重污名理论模型。大学生（样本1：N = 1228；样本2：N = 1368）完成了评估污名和ED症状的在线调查。在每个样本中，分别进行多组路径分析，以检验体重指数（BMI）分类（体重过轻/正常体重、超重、肥胖）是否调节了一个模型，在该模型中，体重污名经历依次与体重偏见内化、身体不满以及五种ED症状相关：暴饮暴食、清除行为、节食、过度运动、增肌行为。结果总体上支持了所评估的模型，并且分别支持了每个BMI类别的个体。尽管不同BMI个体的关联模式有所不同，但这些差异是有限的。本研究结果表明，体重污名对不同ED症状的不利影响并不局限于BMI较高的个体，并且这些关联通常由相同的机制解释。建议对不同体重范围的个体进行以减少体重偏见内化和身体不满为重点的体重污名干预。支持进一步研究体重污名与多种ED症状之间的关联，而不仅仅是无节制饮食。
