Risk for suicidal behaviour in personality disorders
While it is well known that depression, substance dependence, and schizophrenia are strongly associated with suicide, personality disorder also confers a significant risk, but has been consistently understudied. Borderline personality disorder has been consistently associated with suicide risk; additionally, antisocial personality disorder, and avoidant personality disorder have also been found to have a significant risk but has received little research attention. Research also hints at the possibility that schizoid personality disorder and narcissistic personality disorder could increase the risk for suicide as well. Importantly, stressful life events, such as those involving interpersonal distress and loss, confer a significant risk for those with personality disorders, possibly due to poor coping strategies. Reliable instruments with good psychometric properties need to be established that are sensitive to detecting axis II personality disorders. This text reviews the literature on risk factors and treatment approaches to suicidal behaviour in personality disorders.
