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.
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.
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.
