title: Unplanned versus planned suicide attempters, precipitants, methods, and an association with mental disorders in a Korea-based community sample.
abstract: BACKGROUND
  Studies have consistently reported that a considerable proportion of suicidal attempts are unplanned. We have performed the first direct comparison between planned and unplanned attempts including associated methods and precipitants.
  
  
  METHODS
  A total of 6510 adults, who had been randomly selected through a one-person-per-household method, completed interviews (response rate 81.7%). All were interviewed using the K-CIDI and a questionnaire for suicide.
  
  
  RESULTS
  Two hundred and eight subjects reported a suicide attempt in their lifetime, one-third of which had been unplanned. These individuals exhibited a lower level of education; however, no significant differences were found with regard to age, gender, marital and economic status. Further, 84.0% of unplanned attempters experienced previous suicidal ideation, experiencing their first attempt 1.9 years before ideation. Additionally, 94.4% of unplanned attempters had precipitants for attempts such as familial conflict and it was also found that methods such as the use of chemical agents or falling were three times more common in unplanned than planned attempters. With respect to unplanned attempters, they exhibited a significant association with alcohol use disorder, major depressive disorder, posttraumatic stress disorder, and bipolar disorder. In particular, bipolar disorder was found to be 3.5 times higher in these individuals.
  
  
  CONCLUSIONS
  Results have revealed that unplanned suicide attempters experience suicidal ideation and precipitants prior to their attempt. Further, attempts were associated with affective and alcohol use disorders. Therefore, in order to reduce the number of suicidal attempts, it may be useful to evaluate suicidal ideation concurrent to the treatment of existing mental disorders.
