【 摘 要 】

Background

In light of the increased suicide rate in Korea, it has become important for researchers to examine the various factors associated with it. The purpose of this study is to compare and analyze the difference between suicide attempters and completers in terms of the suicide methods used and the lethality of these methods. In addition, we investigated certain demographic factors that are associated with the choice of suicide method by evaluating their lethality.

Finding

The most frequently used methods of suicide were different in the two groups of attempters and completers. Drug poisoning was the most frequent method in suicide attempters, whereas hanging was the most common method among suicide completers. Drug poisoning, stabbing, and other chemical poisoning were evaluated as relatively non-lethal compared to other suicide methods. While about 70.0% of the suicide attempters used relatively non-lethal methods, almost all suicide completers used lethal methods, based on our classification of the lethality of the method. In terms of gender, males used more lethal methods of suicide.

Conclusions

Suicide completers’ choice of suicide methods are different from those of suicide attempters and tend to be more lethal. Interventions to restrict access to more lethal suicidal methods could be a useful strategy to reduce the suicide rates in South Korea.
