The data were collected from 1,461 high school students living in the middle part in Korea. Researchers collected the data from February to Mar in 1999. Suicidal risk was measured using Suicide Probability Scale and a questionnare which examine adolescent`s suicidal idea and needs for help. Data were analyzed by percentage, x²test, t-test, and F-test. Thirty-one subjects(2.1%) got high risk score, 658 students(45.0%) had moderate level, and 772 students(52.8%) had low risk score. Among the subscales, negative self-evaluation score was highest followed by hopelessness, hostility, and suicidal idea. Negative self-evaluation did not differ by gender or grade. The suicidal risk of the students who had not religion was higher than the students who had religion(P＜.001). Significant proportion(31.5%) of the subjects thought about suicide during previous 6 months. Girls had high score on suicidal idea than boys sand the difference was statisticaly significant(p＜.001). The conflicts within their family members, academic problems, loneliness, and peer relation were major causes for the ideas of suicidal attempt. Most of the subjects who have suicidal idea(62.4%) expressed their thought to their friends and wanted to get helps from friends if they could be captured in crisis. Also they wanted to get some helps from parents by letter or telephone as well as face-to-face conversation. In conclusion, 47.1% of the subjects had suicidal risk above moderate level and significant proportion of them thought about having suicide. It is necessary to develop suicide preventive program for adolescents. Our findings suggest that the program should focus on the problems related to studying and conflicts within the family. It could be recommended to use peer group and to promote effective parent`s supporting skills for their children.
