The purpose of this study was to investigate the effect of personality traits of the middle aged on quality of life while mediated by self-concepts such as self-efficacy and self-derogation, as well as while moderated by subjective socio-economic variables such as economic status, social activities and employment. To verify the conceptual causality model and moderating effects of contextual variables, we analysed 353 cases out of purposively collected 400 cases from a medium sized city. As results, first, conscientiousness of personality traits positively affected quality of life of the middle aged while mediated by self-concepts. Second, neuroticism of personality traits negatively affected quality of life while mediated by self-concepts. Third, agreeableness of personality traits did not eventually affect quality of life, although affected negatively on self-efficacy and positively on self-derogation. Fourth, socio-economic variables such as economic status, social activities and employment moderated various paths in the model, which indicated dynamics of internal variables were affected by contextual variables.

This study investigated the relationships between factors of aggression and satisfaction with life and the differences of irrational belief, primary secondary anger thought, and satisfaction with life among four groups classified based on the levels of hostility and verbal aggression. 268 middle school boys in Chungnam areas served as subjects. The results showed that hostility showed the most negative correlation with satisfaction with life. Stepwise regression analyses showed that hostility negatively predicted satisfaction with life, whereas verbal aggression positively predicted satisfaction with life. Factors of irrational belief, primary/secondary anger thought were negatively correlated with satisfaction with life. Analyses of variances revealed that covert hostility group showed higher scores on self-depreciation, disregard and disappointment in intimate relationship situation, hopelessness, whereas overt hostility group showed higher scores on derogation of others/revenge. In addition, covert hostility group showed lower scores on satisfaction with life than other groups. Finally, limitations of this study and suggestions for future study were discussed.
