Abstract
The purpose of this study was to examine the moderated mediating effect of ego-resilience by self-esteem in the influence of exercise hours during physical education class on depression level. The subjects were 3rd year high school students 2011 (1014 male and 997 female students), which were investigated and released by the Korea national youth policy institute. The SPSS PROCESS macro 3.0 program in SPSS 24.0 program was used. The alpha level was set at 5%. In the case of boys, active exercise hours during physical education reduced depression level and interaction effect with positive self-esteem and high ego-resilience was significantly needed. In the case of female students, active exercise hours during physical education reduced depression level but interaction effect with self-esteem and ego-resilience was not significant. In addition, the direct effect of self-esteem on the level of depression was greater for girls than for boys. This study suggested that flexible ego-resilience and active participation in physical education classes made low depression level to both male and female students.
