Based on the collected data, Pearson's correlation coefficient analysis and hierarchical multiple regression analysis are as follows. First, the higher the job stress of the kindergarten teacher, the lower the life satisfaction, and the higher the ego-resilience, the higher the life satisfaction. In particular, the reward, a sub-variable of job stress, had a significant negative correlation with the kindergarten teacher's ego-resilience and life satisfaction. Second, the predictors of relationship resilience, energy, and reward significantly influenced the life satisfaction of kindergarten teachers, and the relationship resilience was relatively explanatory about life satisfaction. This study suggests that an educational plan to be explored to improve ego-resilience for kindergarten teacher's life satisfaction.
