Abstract
OBJECTIVE: This study aimed to investigate the relative contributions of binge eating, body image disturbance, and body mass index (BMI) to distress and disability in binge-eating disorder (BED). METHOD: A community sample of 174 women with BED-type symptomatology provided demographic, weight, and height information, and completed measures of overvaluation of weight/shape and binge eating, general psychological distress and impairment in role functioning. Correlation and regression analyses examined the associations between predictors (binge eating, overvaluation, BMI), and outcomes (distress, functional impairment). RESULTS: Binge eating and overvaluation were moderately to strongly correlated with distress and functional impairment, whereas BMI was not correlated with distress and only weakly correlated with functional impairment. Regression analysis indicated that both overvaluation and binge eating were strong and unique predictors of both distress and impairment, the contribution of overvaluation to variance in functional impairment being particularly strong, whereas BMI did not uniquely predict functional impairment or distress. DISCUSSION: The findings support the inclusion of overvaluation as a diagnostic criterion or specifier in BED and the need to focus on body image disturbance in treatment and public health efforts in order to reduce the individual and community health burden of this condition.
