This study aimed to examine how internalized weight bias (IWB), body surveillance, and body shame relate to eating pathology in women with diagnosed eating disorders (EDs) across the weight spectrum. Previous research has examined these variables in primarily non-clinical populations, binge eating disorder, and higher weight populations. In a sample of 98 women with diagnosed EDs, the association of IWB, body surveillance, and body shame on the severity of ED symptoms was examined with hierarchical multiple regression analyses. Results indicate that IWB, body surveillance, and body shame significantly predicted global eating pathology, (4, 93) = 40.74, < .001. IWB, body surveillance, and body shame related to global eating pathology, even after controlling for previous weight bias experiences. Analyses with specific symptom clusters found that only body surveillance predicted dietary restraint, only IWB and body shame predicted overvaluation of shape/weight, and only IWB predicted body dissatisfaction. The findings in this study provide initial support for internalized stigma variables (IWB, body surveillance, and body shame) related to ED pathology in a transdiagnostic clinical eating disorder sample across the weight spectrum. Results suggest that further examination of internalized stigma is needed within ED treatment.
本研究旨在探讨内化体重偏见（IWB）、身体监测和身体羞耻感如何与不同体重范围的已确诊饮食失调（ED）女性的饮食病理学相关。以往的研究主要在非临床人群、暴饮暴食症和超重人群中考察了这些变量。在一个由98名已确诊ED的女性组成的样本中，通过分层多元回归分析考察了IWB、身体监测和身体羞耻感与ED症状严重程度之间的关联。结果表明，IWB、身体监测和身体羞耻感显著预测了总体饮食病理学，F(4, 93) = 40.74，p <.001。即使在控制了先前的体重偏见经历后，IWB、身体监测和身体羞耻感仍与总体饮食病理学相关。对特定症状群的分析发现，只有身体监测预测了饮食限制，只有IWB和身体羞耻感预测了对体型/体重的过度重视，只有IWB预测了身体不满。本研究结果为跨诊断临床饮食失调样本中不同体重范围与ED病理学相关的内化耻辱感变量（IWB、身体监测和身体羞耻感）提供了初步支持。结果表明，在ED治疗中需要进一步研究内化耻辱感。
