Why no cognitive body image feature such as overvaluation of shape/weight in the binge eating disorder diagnosis?

Objective: Undue influence of body shape or weight on self-evaluation--referred to as overvaluation--is considered a core feature across eating disorders, but is not a diagnostic requirement for binge eating disorder (BED). This article addresses the relevance of a feature reflecting disturbance in body image for the diagnosis of BED.

Method: The distinction between overvaluation of shape/weight and body dissatisfaction is discussed, and empirical research regarding the concurrent and predictive significance of overvaluation of shape/weight for BED is reviewed.

Results: The literature suggests that overvaluation does not simply reflect concern or distress commensurate with excess weight, is reliably associated with greater severity of eating-related psychopathology and psychological distress, and has reliably shown negative prognostic significance.

Discussion: Overvaluation of shape/weight warrants consideration as a diagnostic specifier for BED.
