Objective: Internalized weight bias (IWB), or negative weight related self-evaluation, is associated with eating-disorder psychopathology and common among patients seeking bariatric surgery, but little is known about the clinical presentation of IWB post-operatively. This study examined IWB and clinical correlates among adult patients with loss-of-control (LOC) eating post-sleeve gastrectomy surgery. Methods: Participants (N = 145) were sleeve gastrectomy patients seeking treatment for eating/weight concerns and experiencing regular LOC eating approximately 6 months following surgery. Eating-disorder features were assessed with the Eating Disorder Examination-Bariatric Surgery Version interview (EDE-BSV) and participants completed established measures assessing IWB, depression, and mental and physical components of quality of life. Results: IWB was not associated significantly with percent excess weight loss, age, or gender, but White participants reported significantly greater IWB than Non-White participants. IWB was significantly associated with greater eating-disorder psychopathology, depression, and lower perceived mental quality of life. Hierarchical regression analysis revealed that IWB significantly predicted variance in eating-disorder psychopathology above and beyond other related variables. Conclusions: Findings suggest that IWB is common and associated with a range of heightened eating-disorder and psychosocial difficulties among patients experiencing LOC eating following bariatric surgery. Future research exploring the longitudinal post-operative prognostic significance of IWB is recommended.
