Previous research suggests that personality differences among individuals with disordered eating may be predictive of symptomatology, treatment response, and prognosis. This study sought to use the MMPI-2-RF to look for personality and psychopathology differences between eating disorder subtypes. The groups examined were participants exhibiting predominantly restricting, binging, or purging behaviors as well as low body weight and nutritional deficiency. Results indicated that participants who exhibited restricting behaviors or had significant weight loss and nutritional deficiency had lower scores on the scales measuring emotional and internalizing dysfunction and higher scores on the scales measuring behavioral externalizing dysfunction. Participants who exhibited binging and purging behaviors had higher scores on the emotional and internalizing scales and lower scores on the behavioral externalizing scales. The opposite patterns suggest that different treatment methods may best address the specific and different symptoms of each eating disorder group.
