Subjective binge eating: a marker of disordered eating and broader psychological distress.

Purpose: There is building, but limited evidence to suggest that subjective binge eating (SBE) is clinically concerning. The current study examined associated features of SBEs including disordered eating, body shame, negative affect, and interpersonal problems, as well as how SBE occurrence relates to other daily eating experiences.

Methods: Participants were 400 individuals recruited via internet snowball or Amazon Mechanical Turk, including 132 with at least one SBE [with or without objective binge eating episodes (OBEs)] in the prior 3 months, 135 with at least one OBE (and no SBEs) in the prior 3 months, and 133 with no loss of control eating in the prior 3 months nor a likely lifetime history of anorexia nervosa. Participants responded to questionnaires assessing eating disorder behaviors (i.e., frequency of compensatory behaviors, dietary restriction), body shame, negative affect (depressive/anxiety symptoms), interpersonal difficulties, and perception of daily eating experiences.

Results: Individuals with SBEs had higher numbers of vomiting, laxative misuse and hard exercise episodes, dietary restriction, body shame, depressive and anxiety symptoms, and negative perceptions of daily eating experiences as compared to those with only OBEs and no loss of control eating.

Conclusion: These results suggest that SBEs (whether on their own or combined with OBEs) are more related to disordered eating symptoms, body image concerns, depressive/anxiety symptoms, and general eating distress than OBEs on their own, suggesting that clinicians may view SBEs as markers of concern across domains.

Level Of Evidence: III, well-designed group-comparison regression analysis.
