OBJECTIVE: Suicide is the leading cause of death for adolescents. The internet is widespread in Korea and has influence on mental health of adolescents. This study aims to investigate the relationship between the internet use and suicidal behavior resulting from adolescent depression.

Suicidal behavior was assessed by Columbia Suicide Severity Rating Scale. Patients were inquired about their internet use using questionnaires and other clinical variables using Beck Depression Inventory, Beck Suicidal Ideation Scale, Revised Children's Manifest Anxiety Scale, Internet Game Addiction Scale and Physical Abuse Scale.
RESULTS: The patients within the high-risk group were more prone to searching for the word 'suicide' on the internet and having suicidal idea compare to the patients within the low-risk group. Among the high-risk group, the patients who searched for the word 'suicide' tended to be more anxious compared to the patients who did not search the word.
