Prospective predictors of suicide attempts in borderline personality disorder at one, two, and two-to-five year follow-up.
Efforts to identify reliable predictors of suicidal behavior in Borderline Personality Disorder have been confounded by the marked dimensional heterogeneity of the disorder, frequent comorbidity with other high risk disorders, debilitating social and vocational consequences of BPD over time. Using survival analyses, we assessed the predictive association between risk factors in each of these symptom domains and suicide attempts in BPD subjects followed for 12 months, 18-24 months and 2-5 years. The suicide attempt rate was 19% in the first year, 24.8% through the second year. The risk of suicidal behavior among 137 BPD subjects completing the first 12 months was increased by comorbid MDD and poor social adjustment. Outpatient treatment decreased short-term risk. Among 133 subjects completing 18-24 months in the study, the relative risk of a suicide attempt was increased by hospitalization (prior to any attempt), and poor social adjustment. Among 122 subjects followed for 2-5 years, increased risk was associated with hospitalization and medication visits (prior to any attempt), an attempt in the first year, and a low GAS score at baseline. Long term risk was decreased by "any outpatient treatment." Predictors of suicidal behavior in BPD change over time. MDD has a short-term effect on suicide risk, while poor social adjustment may increase risk throughout each follow-up interval. Assessing and supporting family, work, and social relationships may decrease suicidal behavior in BPD, and should be a principal focus of long-term treatment.
