title: Axis II comorbidity of borderline personality disorder in adolescents.
abstract: OBJECTIVE
  The objective of the present study was to explore the comorbidity of borderline personality disorder (BPD) with other personality disorders in adolescents and compare these comorbidities in male and female subjects.
  
  
  METHODS
  The sample was drawn from a European research project investigating the phenomenology of BPD in adolescence (EURNET BPD). A total of 85 BPD patients (11 boys and 74 girls) with a mean age of 16.3 years were included in the study.
  
  
  RESULTS
  According to the results of the Structured Interview for DSM-IV Disorders of Personality, obsessive-compulsive (35.3%), antisocial (22.4%), avoidant (21.2%), dependent (11.8%) and paranoid (9.4%) personality disorders had significant co-occurrences with BPD. Although none of the gender differences was statistically significant, we observed a trend towards higher rates of antisocial personality disorders in men (45.5%) than in women (19%).
  
  
  CONCLUSIONS
  The study results confirmed the frequency of Axis II comorbidity in adolescents with BPD and, for the first time, evidenced a differential pattern of comorbidity in males and females. This differential pattern must be taken into account when developing treatment strategies for adolescents with BPD.
