Screening for Axis II personality disorders in women with bulimic eating disorders.

The Personality Diagnostic Questionnaire (PDQ) was completed by 628 eating-disordered women: 300 with normal-weight bulimia, 15 with anorexia nervosa with bulimic features, and 313 with subdiagnostic eating disorders. Three-quarters (75%) of subjects with normal-weight bulimia had personality disorder diagnoses, compared with 50% of those with subdiagnostic eating disorders. The average number of separate PDQ diagnoses was 2.7 for the normal-weight bulimia group, 2.5 for the group with anorexia nervosa with bulimic traits, and 1.5 for the subdiagnostic group. The most common PDQ diagnoses were schizotypal, histrionic, and borderline disorders, but avoidant and dependent personality features also occurred. Personality disturbances may be common in patients with eating disorders.
