Predictors of short- and long-term recurrence of suicidal behavior in borderline personality disorder. 
To evaluate the incidence of suicidal outcomes and risk factors for short- and long-term recurrence of suicidal behavior (SB) among high-risk borderline personality disorder (BPD) patients during a 24-month prospective follow-up period.  A multicenter prospective cohort study was designed to compare data obtained from 136 patients admitted to the emergency department for current suicidal ideation (SI) or a recent suicide attempt (SA).  Subjects were clinically evaluated and monitored for a new SA or suicide.  The incidence of a new SA was 25.63 events/100 persons-year, and one patient died by suicide.  Child sexual abuse (CSA) was the only significant predictor throughout the complete follow-up period.  The absence of prior psychiatric treatment predicts the recurrence of SB in the first 6 months of follow-up.  Patient age, poor psychosocial functioning before hospitalization, age at first SA, and having multiple suicide attempts increased risk of SB recurrence at the long-term period (24th months).  In addition, there was an interaction between CSA and poor psychosocial functioning that increased risk of SB.  The risk of recurrence was higher during the first 6 months.  Risk factors at 6 and 24 months vary.  These findings are important for implementing suicide strategies.
