Note. HW = individuals with non-eating-disordered higher body weight (BMI>25 kg/m2); BN = core features of bulimia nervosa; BED = core features of binge-eating disorder; AN = core features of anorexia nervosa; BMI= body mass index; BDI = Beck Depression Inventory; EDE-Q = Eating Disorder Examination – Questionnaire. Restraint, Overvaluation, and Dissatisfaction are subscales calculated from the EDE-Q brief version and Preoccupation with food and eating and Preoccupation with shape and weight are items on the EDE-Q; possible scores range from 0 through 6 with higher scores indicating greater psychopathology.
