10-Year Outcome of Suicidal Behavior in Borderline Personality Disorder

Abstract

Prospective predictors of suicide attempts were assessed in 118 subjects with borderline personality disorder (BPD) after 10 or more years of follow-up. Mean (SD) time to follow-up was 14.4 (4.7) years. Subjects were predominately female (78.8%), Caucasian (81.4%), and of lower socioeconomic status. Initial recruitment was evenly balanced between inpatient, outpatient, and non-patient (community) sources. In the 10-year interval, 55 subjects (46.6%) attempted suicide. Compared to baseline, suicidal ideation, number of attempts, and non-suicidal self-injury diminished markedly. Core symptoms of BPD, substance abuse, and alcohol use disorders decreased significantly; however, major depressive disorder (MDD) remained constant at 50%. Forty-four percent of subjects had poor psychosocial, vocational, and economic outcomes. Psychosocial outcome was independent of suicide history and any treatment. Increased risk was associated with interval hospitalization prior to any attempt (illness severity), as well as poor social, vocational, and psychosocial functioning at baseline.
