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.
