Personality subtypes in male patients with eating disorder: validation of a classification approach.

In the present study, we investigated personality subtypes and their correlates in a sample of 132 male patients with eating disorder (ED). All patients filled out the Temperament and Character Inventory-Revised, the Eating Disorder Inventory-2, and the Symptom Checklist-90-Revised. Three personality subtypes emerged. Cluster 1, the adaptive-like subtype, was characterized by a high prevalence of eating-disorder-not-otherwise-specified and low levels of ED and general psychopathology. Cluster 2, the average or socially detached subtype, showed a high prevalence of eating-disorder-not-otherwise-specified, more social problems, less motivation for treatment, and an intermediate position on the psychopathology dimension between patients of clusters 1 and 3. Finally, cluster 3, the maladaptive subtype, was characterized the highest prevalence of bulimia nervosa and the highest scores on ED and general psychopathology. Our data support the presence of the 3 personality subtypes in male patients with ED. Future studies need to address whether patients of different subtypes differ with respect to therapy outcome.
