In addition, our use of self-report measures of binge eating may have affected results. We chose to examine continuous measures of binge eating to enhance statistical power, and we included two separate binge eating measures (i.e., MEBS Binge Eating subscale and the DEBQ Emotional Eating subscale) to increase confidence in our pattern of results. However, self-report measures, as opposed to interviews, are thought to overestimate the prevalence of eating disorder symptoms and syndromes, particularly binge eating (Fairburn & Beglin, 1994). Thus, future studies would benefit from looking at binge eating using interview methods in addition to self-report questionnaires Finally, BN is associated with a host of cognitive and behavioral symptoms in addition to binge eating. For this reason, we cannot be sure that our results generalize to patients with BN. Future research is needed to examine moderation of genetic influences in clinical samples.
