A262 Negative Affect and Loss of Control Eating among Bariatric Surgery Patients: A Preliminary Ecological Momentary Assessment Investigation
Disordered eating following bariatric surgery: a review of measurement and conceptual considerations
Eating disorders are associated with significant medical morbidity and mortality and serious psychological impairment. Individuals seeking bariatric surgery represent a high-risk group for evidencing disordered eating and eating disorders, with some patients experiencing the persistence or onset of disordered eating postsurgery. This review synthesizes the available literature on problematic or disordered eating in the bariatric field, followed by a review of measurement and conceptual considerations related to the use of eating disorder assessment tools within the bariatric population

Differences in Affective Dynamics Among Eating Disorder Diagnostic Groups.
Emotion regulation theories suggest that affect intensity is crucial in the development and maintenance of eating disorders. However, other aspects of emotional experience, such as lability, differentiation, and inertia, are not as well understood. This study is the first to use ecological momentary assessment (EMA) to examine differences in several daily negative affect (NA) indicators among adults diagnosed with anorexia nervosa (AN), bulimia nervosa (BN), or binge eating disorder (BED). Using EMA data from three large studies, a series of linear mixed models showed that participants in the AN and BN groups experienced significantly greater NA intensity and better emotion differentiation than participants in the BED group. Alternatively, the BN group demonstrated significantly greater NA lability than the AN group and greater NA inertia than the BED group. These results suggest that several daily affective experiences differ among eating disorders diagnostic groups and have implications towards distinct conceptualizations and treatments
