title: Individuals with single versus multiple suicide attempts over 10years of prospective follow-up.
abstract: BACKGROUND
  The study attempted to identify characteristics that differentiate multiple suicide attempters from single attempters in individuals with personality disorders (PDs) and/or major depression.
  
  
  METHODS
  Participants were 431 participants enrolled in the Collaborative Longitudinal Study of Personality Disorders from July 1996 to June 2008. Suicide attempts were assessed with the Longitudinal Interval Follow-up Evaluation at 6 and 12months, then yearly through 10years. Logistic regression was used to compare single attempters to multiple attempters on Axis I and II psychiatric disorders and personality trait variables.
  
  
  RESULTS
  Twenty-one percent of participants attempted suicide during the 10years of observation, with 39 (9.0%) reporting a single suicide attempt and 54 (12.5%) reporting multiple suicide attempts. Although no significant differences in were found in baseline Axis I disorders, multiple attempters were significantly more likely to meet criteria for borderline personality disorder and to have higher impulsivity scores than single attempters.
  
  
  CONCLUSIONS
  These results underscore the importance of considering both personality disorders and traits in the assessment of suicidality.
