Diagnostic of personality disorders in adolescence according to SCID-II

Objectives: The aim of the present study was to ascertain whether the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II) is applicable for use with adolescents. Furthermore, the diagnostic concordance between SCID-II and the clinicians' estimations of personality disorders (PD) is assessed. In addition, we identified predicting factors for personality disorders in adolescent psychiatric inpatients. Methods: 110 adolescent psychiatric inpatients aged 14-18 years were assessed by means of SCID-II and a personality and disorder inventory (PSSI). Results: 32.7% of the inpatients met the criteria for PD according to SCID-II. While agreement between the presence of any PD based on SCID-II and that found according to clinicians' estimations was low, moderate and very good agreement between SCID-II and clinicians' estimations was found with regard to borderline PD and histrionic PD. Logistic regression analyses identified "anorexia nervosa (binge-purging)", "attention-deficit/hyperactivity disorder/conduct disorder (ADHD/CD)" and "socioeconomic status" as good predictors for PD. Conclusions: The SCID-II - which was primarily developed for use with adults - is suitable for use among adolescents. Anorexia nervosa (binge-purging type) and ADHD/CD are closely associated with the development of PD in adolescents.
