Parental sexual abuse and suicidal behaviour among women with major depressive disorder.

OBJECTIVE: Women with major depressive disorder (MDD) and childhood sexual abuse histories have an increased risk for suicidal behaviours, but it is unclear whether specific abuse characteristics contribute to risk. We aimed to examine the contributions of abuse characteristics to lifetime history of suicide attempts and multiple suicide attempts, independent of posttraumatic stress disorder and borderline personality disorder.

METHOD: Women with MDD and sexual abuse histories (n = 106) were assessed regarding sexual abuse characteristics, psychiatric diagnoses, and suicide attempts.

RESULTS: In multivariate logistic regressions, the odds of having multiple suicide attempts increased 12.27-fold when childhood sexual abuse was perpetrated by a parent figure or a parent, compared with a nonparent.

CONCLUSIONS: Parental perpetration of sexual abuse increases the likelihood of multiple suicide attempts among women outpatients. The relationship of the perpetrator to the abused woman is important in suicide risk evaluation and treatment planning.
