Fig. 1. Negative affect on the rest day (a) and stress day (b) in controls and patients with IBS. On the rest day, patients with IBS showed greater negative affect at baseline (*p = .051) and after the meal (*p < .05). On the stress day, patients with IBS reported greater negative affect in response to the stressor (⁺p < .05), and they showed a greater decrease in negative affect after the recovery period (*p < .05). The data are shown as mean and SEM. Time points 1 and 2 are preprandial; 3 to 5 are postprandial.
