Should binge eating disorder be included in the DSM-V? A critical review of the state of the evidence

Abstract

Binge eating disorder (BED) was introduced in 1994 as a provisional eating disorder diagnosis. The core symptom is recurrent binge eating in the absence of inappropriate compensatory behaviors and/or extreme dietary restraint. This review examines the status of the literature on BED according to five criteria that have been proposed to determine whether BED warrants inclusion in the psychiatric nosology as a distinct eating disorder. We conclude that each of these criteria was met. There is a commonly accepted definition of and assessment approach to BED. The clinical utility and validity of BED have been established, and BED is distinguishable from both bulimia nervosa and obesity. BED should be included in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders.
