OBJECTIVES: This study investigated the utility of DSM-5 indicators of loss of control (LOC) eating in adult bariatric surgery patients who presented with binge-eating episodes. METHODS: Participants (all women) were 40 preoperative and 28 postoperative bariatric surgery patients reporting objective binge eating (OBE), 46 preoperative and 52 postoperative with subjective binge-eating (SBE), 53 bulimia nervosa (BN) controls, and 34 binge-eating disorder (BED) controls. Face-to-face Eating Disorder Examination interviews and questionnaires were administered. ANOVA, T-test, χ 2 , and regressions compared the groups in terms of LOC indicators endorsed and to explain disordered eating psychopathology. RESULTS: The indicator most commonly reported by bariatric patients with OBE was "feeling disgusted" (90% and 75% of pre- and postoperative groups), and the least endorsed was "eating alone" (40 and 28.6%). These indicators were reported by >84.9% of the BN and BED. Bariatric patients (pre- or post-surgery) with OBE only reported a higher number of indicators than patients with SBE only (t(150) = 2.34, p = .021). A higher number of indicators reported were associated with increased eating-related psychopathology (F(1,134) = 31.06, p < .001), but only for the post-surgery patients. CONCLUSIONS: The LOC indicators proposed by DSM-5 need to be refined or revised for the bariatric population. Highlights Bariatric patients endorse fewer LOC indicators than BN or BED during a binge-eating episode. Some of the DSM-5 LOC indicators may not be suited to assess episodes of loss of control eating among bariatric patients. The Higher the number of LOC indicators reported, the higher the eating-related psychopathology.
