The purpose of this study was to investigate the role of self-esteem as a moderator of the factors influencing suicidality among middle-schoolers.
Moderated multiple regression analysis was applied to assess the influence of happiness, depression, and hostility on suicidality and to determine the degree to which self-esteem served as a moderator of those relationships. Data were collected from 268 students at a middle school in Busan, Korea, using a self-administered structured questionnaire.
Happiness, depression, and hostility had significant direct effects on suicidality. Self-esteem showed no direct effect, but had a significant moderating effect on the relationship between hostility and suicidal behavior.
These results suggest that various interventions, such as counseling programs, should be designed to alleviate hostility and depression and to enhance happiness and self-esteem among early adolescents.
Korean summary
본 연구는 중학생의 자살성향에 영향을 주는 주요 요인을 식별하고, 자아존중감의 조절효과를 확인하여 청소년 자살예방 방안 모색을 위한 실마리를 제공하고자 하였다. 실증자료의 분석 결과 자살성향에 행복, 우울, 적대감이 유의한 직접효과, 그리고 조절변수인 자아존중감이 적대감과 상호작용하여 유의한 조절효과를 보였다(p<0.05). 청소년 자살 예방의 실효성을 높이기 위해서는 행복감의 증진, 우울과 적대감의 완화 등 원인변수에 대한 개입과 동시에 조절변수인 자아존중감을 향상시키기 위한 가정과 학교의 체계적인 노력이 필요함을 시사한다.

AbstractAbstract PDF
The objectives of this study are two-fold : to identify geographic variations in the rate of tonsillectomy and adenoidectomy(T and A) and appendectomy and analyze the socioeconomic variables and health resources which affect geographic variation in the rate. The nationwide three month's cases of the two surgical procedures in 1991 are obtained from the record of the National Federation of Medical Insurance. The analysis shows two to ten-fold variations in the regional rates for the performance of two common procedures such as T and A and appendectomy. T and A shows a bigger regional variations than appendectomy. As a result of multiple regression, the factor of bed supply has been found significant for the dependent variable of the rate of T and A. The findings of large variations in the rate of surgical procedures throughout the country would have important implications for allocating scarce resources and managing quality of care. Further analysis is needed for the elaboration of the above implications.
