Abstract


OBJECTIVE
Although suicide is a serious public health concern for adolescents, there is a lack of studies that explore its risk factors in the Republic of Korea. The present study aims to investigate risk factors associated with suicidal behaviors in Korean adolescents.
METHODS
Participants consisted of 2258 middle and high school students who completed a series of questionnaires regarding suicide ideation or attempts, non-suicidal self-injuries, depression, impulsivity, drinking behaviors, and negative life events, including peer bullying.
RESULTS
Among the participants, 8.3% of students reported suicide ideation, while 3.2% reported a history of a suicide attempt in the past 12 months. Depression, peer-victimization, internet-related delinquency, and positive attitudes toward suicide were associated with suicidal ideations and attempts. Adverse life events were also associated with suicide ideation, but not attempts, while not living with both parents and poor family relationships were associated with suicide attempts, but not ideations. Non-suicidal self-injuries were associated with both suicide ideations and attempts. Students with suicidal ideations and attempts can be differentiated depending on the presence of self-injury.
CONCLUSION
In addition to depression or behavioral problems, non-suicidal self-injuries and lack of support from family may also play significant roles in suicide attempts in adolescents. To facilitate the prevention of suicide in adolescents, longitudinal studies should be followed to confirm the risk factors identified in this study.
