Childhood sexual abuse predicts poor outcome seven years after parasuicide.

BACKGROUND

There is substantial empirical research linking borderline personality disorder with prolonged mental instability and recurrent suicidality. At the same time, a growing body of observations links borderline personality disorder to sexual abuse and other forms of abuse and trauma in childhood. The aim of this study was to investigate among patients admitted for parasuicide the predictive value for outcome 7 years after the parasuicide of a diagnosis of borderline personality disorder compared to the predictive value of a history of childhood sexual abuse.

METHODS

Semi-structured interviews were conducted at the time of the index parasuicide, with follow-up interviews 7 years later. In addition, information was collected from medical records at the psychiatric clinic. A logistic regression analysis was used to assess the specific influence of the covariates borderline personality disorder, gender and reported childhood sexual abuse on the outcome variables.

RESULTS

Univariate regression analysis showed higher odds ratios for borderline personality disorder, female gender and childhood sexual abuse regarding prolonged psychiatric contact and repeated parasuicides. A combined logistic regression model found significantly higher odds ratios only for childhood sexual abuse with regard to suicidal ideation, repeated parasuicidal acts and more extensive psychiatric support.

CONCLUSION

The findings support the growing body of evidence linking the characteristic symptoms of borderline personality disorder to childhood sexual abuse, and identify sexual abuse rather than a diagnosis of borderline personality disorder as a predictor for poor outcome after a parasuicide. The findings are relevant to our understanding and treatment of parasuicide patients, especially those who fulfil the present criteria for borderline personality disorder.
