Threatened Self-concept and Changes in the Demographic Structures of Suicide in South Korea: A Social Psychological Approach

Abstract

The main purpose of this study is to examine changes in the demographic structures of suicide incidents in South Korea for about 30 years and to explain them theoretically. Social psychological concepts of self-concept and threatened self are introduced as the theoretical basis for explanation. From this theoretical approach four research hypothesis are derived and tested. PAI(percentage age involvement) index and comparison of the structures of Persons residual calculated by poison regression analysis are used for the analysis for suicide incidents data. This study reveals that there has been changes in age-specific suicide incidents structures from bimodal to upward-sloping shapes and gender gap in speed of those changes. And this study found that the financial crisis of the late 90’s made great changes in the structures in age-specific suicide incidents in both genders.
