[Personality disorders in adolescent patients with anorexia and bulimia nervosa].

OBJECTIVE

The present study aimed to ascertain the occurrence of personality disorders (PD) in adolescent patients with anorexia (AN) and bulimia nervosa (BN) by means of the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II).

METHOD

99 female adolescent patients (57 AN - restrictive type, 17 AN - binge-purging type, 25 BN; M(age) = 16.3 +/- 1.6) were consecutively assessed by means of SCID-II. Furthermore, the influence of age, axis-I-comorbidities, and type of treatment according to PD were examined.

RESULTS

30.3% of the patients met the criteria for PD according to SCID-II. AN patients of the binge-purging type showed higher prevalences of PD and higher dimensional scores than the other eating disorder groups. Moreover, our findings indicate that age and axis-I-comorbidities are associated with the development of PD.

CONCLUSION

Significant differences in the occurrence of PD in the three eating disorder groups were found. Patients of the AN binge-purging type are more often affected than restricting AN or BN patients are. This, and also the influence of age and axis-I-comorbidities, should be taken into account in the treatment of patients with eating disorders.
