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.
628名饮食失调女性完成了人格诊断问卷（PDQ）：300名体重正常的贪食症患者、15名具有贪食特征的神经性厌食症患者和313名亚诊断性饮食失调患者。体重正常的贪食症患者中有四分之三（75%）被诊断为人格障碍，相比之下，亚诊断性饮食失调患者中有50%被诊断为人格障碍。体重正常的贪食症组平均每人有2.7项独立的PDQ诊断，具有贪食特征的神经性厌食症组为2.5项，亚诊断组为1.5项。最常见的PDQ诊断是分裂型、表演型和边缘型障碍，但回避型和依赖型人格特征也有出现。人格障碍在饮食失调患者中可能很常见。
