Gender differences and similarities in aggression, suicidal behaviour, and psychiatric comorbidity in borderline personality disorder.Objective: We examined gender differences and similarities in aggression, impulsivity, suicidal behaviour, and psychiatric comorbidity in men and women with borderline personality disorder (BPD) compared with healthy controls. Method: A community sample of 511 participants (healthy controls: 81 men and 82 women; BPD patients: 145 men and 203 women) were rigorously characterized using structured diagnostic interviews and symptom severity assessments. Results: In comparison with women with BPD, men were less educated, had higher total Barratt Impulsivity Scale (BIS), BISmotoric impulsiveness and BIS-non-planning impulsiveness subscale, total Buss-Perry Aggression Questionnaire (BPAQ), and BPAQ-physical aggression subscale scores. Men with BPD were more likely to have comorbid narcissistic, antisocial, paranoid, and schizotypal personality disorders, alcohol and substance use disorders but less likely to have dependent and obsessivecompulsive personality disorders compared to women with BPD. There was a trend toward higher maximum lethality of suicide attempts in men suicide attempters compared with women suicide attempters but no difference between men and women with regard to the proportion of suicide attempters or the number of suicide attempts. Conclusion: Men with BPD are more impaired and may be at higher risk of dying by suicide compared to women with BPD.
Significant outcomes• Men with borderline personality disorder (BPD) are more aggressive, impulsive, and overall impaired in comparison with women with BPD.• Men with BPD may be at higher risk of dying by suicide than women with BPD. • Gender differences in proportion of suicide attempters observed in the general population are absent in individuals with BPD.
Limitations• All participants were recruited in a major metropolitan area on the East Coast of the United States, and therefore, the results of the study may not be generalizable to rural areas or other countries.
