Dimensional Analysis of Emotion Trajectories Before and After Disordered Eating Behaviors in a Sample of Women with Bulimia Nervosa

Bulimia nervosa (BN) is robustly associated with mood disturbances (e.g., Haedt-Matt and Keel, 2011; Smyth et al., 2007). According to the affect regulation model, binge eating and purging are maintained because both are negatively reinforced via temporary relief of emotional distress (Hawkins and Clement, 1984; Polivy and Herman, 1993). Research utilizing ecological momentary assessment (EMA) methodology supports this hypothesis by demonstrating the trajectory of negative affect increases prior to and decreases following bulimic behaviors (e.g., Smyth et al., 2007; Berg et al., 2013).
