Thirty-seven suicidal attempters and depressed patients were examined in an effort to determine the importance of life stress as factors in suicidal attempt. The results were as follows : 1) The suicide group was found to be younger than the depressed group(P<0.05). Sex distribution and socioeconomic status score were revealed no significant difference between two groups. 2) Structured Interview Guide for Hamilton Depression Score(SIGH-D) was not significantly different between two groups. 3) Total stress score and total negative stress score were significantly high in suicidal group than in depressed group(P<0.05), but total positive stress score was not significantly different between two groups. As a result, this study suggested that suicidal attempt is high in early adulthood group and in high stressed group under the control of degree of depression.
