Objectives: Binge eating is common in adults with obesity. The Diagnostic and Statistical Manual for Psychiatric Disorders describes five indicators of binge eating (eating more rapidly than usual; eating until uncomfortably full; eating large amounts of food when not physically hungry; eating alone because of embarrassment over how much one is eating; and feeling disgusted with oneself, depressed, or very guilty after overeating), but their validity is unclear. Method: We examined preliminary associations between the five indicators and binge versus nonbinge episodes among 50 adults with obesity via ecological momentary assessment. Results: Generalized linear models revealed that, relative to nonbinge episodes, self-reported binge episodes were associated with lower pre-episode hunger (p =.004), higher postepisode fullness (p <.001), a greater likelihood of reporting moderate to extreme shame prior to eating in conjunction with eating alone (p <.001), and a greater likelihood of reporting moderate to extreme disgust, depression, and/or guilt after eating (p <.001), but not with eating more rapidly than usual (p =.85). Discussion: Results support the validity of most binge-eating indicators, although the utility of the rapid eating criterion is questionable. Future research should examine whether modifying these indicators in binge-eating interventions would reduce the occurrence of loss of control and/or overeating.
