Assessing the functional nature of binge eating in the eating disorders

This study explored the functional nature of binge eating through the development of a new self-report instrument called the Binge Eating Adjective Checklist. Participants were 405 adult females who presented to a specialized eating disorders clinic. A subset of participants with bulimia nervosa also completed additional psychometrics and treatment. Those participants who reported greater reductions in negative affective and somatic states during a binge episode were also more distressed on measures of perfectionism, self-esteem, ineffectiveness, and interceptive awareness. They were also less likely to achieve abstinence from bingeing and vomiting over the course of treatment. Thus, the instrument appears to offer a methodology for studying the phenomenology of binge eating and the prediction of therapeutic outcome in bulimia nervosa.
