Negative affect and binge eating: Assessing the unique trajectories of negative affect before and after binge-eating episodes across eating disorder diagnostic classifications.

ABSTRACT:

Objective

Ecological momentary assessment (EMA) studies suggest that among individuals who binge eat, emotional states and binge eating are functionally related. However, it is unclear whether the trajectory of negative affect (NA) is the same across diagnostic groups or if specific changes in affect are unique to each diagnostic category. This study examined the moderating effect of diagnosis on the trajectory of negative affect before and after binge eating.

Method

Adults with eating disorder diagnoses (anorexia nervosa [AN] = 118, bulimia nervosa [BN] = 133, binge-eating disorder [BED] = 112) completed an EMA where they reported binge eating and negative affect throughout the day. Generalized estimating equation analyses were used to model the trajectories of NA before an
