*3.1. Punishment Sensitivity*

With respect to punishment sensitivity (Figure 1), all ED groups scored significantly higher on punishment sensitivity (BIS) compared to healthy controls and patients with obesity. Patients with AN (AN-R+AN-BP) scored significantly higher on punishment sensitivity than patients with BN. Obesity groups did not differ significantly from healthy controls (except Class II obesity—BE) on punishment sensitivity, and scored significantly lower on punishment sensitivity than ED groups. Within the obesity groups, Class III obesity patients with binge eating reported significantly higher punishment sensitivity levels than the other obesity groups.
