The purpose of this research is to understand how elementary students’ stress coping mediates the
correlation between their ego resiliency and happiness. For this research, a total of 348 students - 5th and
6th graders from Gyeonggi-do ‘S’ city, was surveyed, and the result of the statistical analysis is the
following: First, the elementary students’ ego resiliency has a strong correlation between the happiness and
the stress-coping, a positive correlation between the happiness and the socially supported stress-coping, and
a negative correlation between the happiness and the aggressive stress-coping. Second, the elementary
students’ active stress-coping and the socially supported stress-coping partially mediate the correlation
between their ego resiliency and happiness, and the result is proven to be a significant statistical variable.
Thus, a child who has high ego resiliency is active in a stressful situation, has a high tendency to use
socially supported stress-coping, and has high level of happiness; meanwhile, a child who has low ego
resiliency has a high tendency to use aggressive stress-coping and has low level of happiness. Therefore, in
order to increase elementary students’ level of happiness, it is necessary to seek and provide programs for
students to be more active, to let them utilize socially supported stress-coping, and to increase their ego
resiliency.
