This study aimed to investigate the relationship between weight bias internalization and eating disorder psychopathology in treatment-seeking patients with severe obesity using a network approach. Two thousand one hundred and thirteen patients with obesity were consecutively admitted to a specialist clinical unit for obesity and were recruited from January 2016 to February 2023. Body mass index was measured, and each patient completed the Weight Bias Internalization Scale (WBSI) and the Eating Disorder Examination Interview (EDE). Network analysis showed that the most central and highly interconnected nodes in the network were related to the EDE items exposure avoidance, dissatisfaction with shape, and wanting an empty stomach. Bridge nodes were found, but the bootstrap difference test on expected bridge influence indicated non-significant centrality differences. Nevertheless, the eating disorder psychopathology and weight bias internalization network structure in patients seeking treatment for obesity indicate the prominent roles of body dissatisfaction and control of eating and weight in these psychological constructs. This finding, if replicated, could pave the way for a new understanding of the psychological mechanisms operating in patients with obesity.
本研究旨在采用网络方法探讨就诊于重度肥胖症专科临床单位的患者中体重偏见内化与饮食障碍病理之间的关系。2016 年 1 月至 2023 年 2 月期间，连续招募了 2113 名肥胖症患者。测量体重指数，每位患者均完成体重偏见内化量表（WBSI）和饮食障碍检查访谈（EDE）。网络分析显示，网络中最核心和高度互联的节点与 EDE 项目回避暴露、对体型不满和渴望空腹有关。发现了桥节点，但对预期桥影响的引导差异测试表明，中心度差异不显著。尽管如此，寻求肥胖症治疗的患者的饮食障碍病理和体重偏见内化网络结构表明，身体不满和对饮食和体重的控制在这些心理结构中起着突出作用。如果这一发现得到复制，可能为理解肥胖症患者的心理机制开辟新的途径。
