Binge eating disorder (BED) was recently included in the DSM-5. The prevalence rate for BED using the DSM-IV-TR research criteria tends to be higher in bariatric surgery candidates than the normative population; however, no studies have examined how many more bariatric surgery candidates will meet the new, less conservative criteria of DSM-5. We explore the current BED prevalence rate change in a sample of bariatric surgery candidates.
Data were obtained for 1,283 bariatric surgery candidates. 84 men and 213 women were diagnosed with current BED using DSM-IV-TR research criteria. A semi-structured interview, the binge eating scale (BES), and a Minnesota Multiphasic Personality Inventory—2 Restructured Form (MMPI-2-RF) were given to every patient as part of standard procedures mandated by the facility.
Results and Discussion
An additional 3.43% (p < .001) of bariatric surgery candidates met the diagnostic threshold for BED when using DSM-5 criteria. These individuals were demographical similar and produced similar MMPI-2-RF and BES scores when compared with patients who met DSM-IV-TR criteria for BED. Thus, the current investigation indicates that individuals meeting BED criteria based on DSM-5 are similar to those meeting the more conservative diagnostic threshold outlined in DSM-IV-TR in a sample of bariatric surgery candidates. © 2014 Wiley Periodicals, Inc.
