Binge eating disorder is a new diagnostic concept. The cardinal feature is binge eating but, in contrast to bulimia nervosa, the binge eating is not accompanied by inappropriate compensatory behavior such as self-induced vomiting and the misuse of laxatives. In a study of the causes of binge eating disorder, Fairburn et alArticle found that its antecedent risk factors consisted primarily of adverse childhood experiences, parental depression, negative self-evaluation, and childhood obesity. In contrast, perfectionism and pronounced vulnerability to obesity seemed to be especially characteristic of bulimia nervosa. These findings provide support for the validity of the distinction between binge eating disorder and bulimia nervosa.
