Objective Binge Eating Disorder (BED) is among the most common psychiatric disorders in bariatric surgery candidates. The Minnesota Multiphasic Personality Inventory‐2 Restructured Form (MMPI‐2‐RF) is a broadband, psychological test that includes measures of emotional and behavioral dysfunction, which have been associated with BED behaviors in bariatric surgery candidates; however these studies have lacked appropriate controls. In the current study, we compared MMPI‐2‐RF scale scores of bariatric surgery patients diagnosed with BED (BED+) with BMI‐matched controls without BED (BED–). Method Three‐hundred and seven BED+ participants (72.64% female and 67.87% Caucasian; mean BMI of 51.36 kg/m 2 [SD = 11.94]) were drawn from a large, database ( N = 1304). Three‐hundred and seven BED– participants were matched on BMI and demographics (72.64% female, 68.63% Caucasian, and mean BMI of 51.30 kg/m 2 [SD = 11.70]). Results The BED+ group scored significantly higher on measures of Demoralization, Low Positive Emotions, and Dysfunctional Negative Emotions and scored lower on measures of Antisocial Behaviors, reflecting behavioral constraint. Optimal T ‐Score cutoffs were below the traditional 65 T score for several MMPI‐2‐RF scales. MMPI‐2‐RF externalizing measures also added incrementally to differentiating between the groups beyond the Binge Eating Scale (BES). Discussion BED+ individuals produced greater elevations on a number of MMPI‐2‐RF internalizing scales and externalizing scales. Use of the test in conjunction with a clinical interview and other self‐report data can further aid the clinician in guiding patients to appropriate treatment to optimize outcome. © 2013 Wiley Periodicals, Inc.
