摘要:The purpose of this study is to explore the effects of cognitive flexibility on the five EPOCH well-being components: engagement, perseverance, optimism, connectedness and happiness. The study also investigates the mediating roles of coping styles (i.e., active coping and negative coping) in this relationship. The participants consisted of 488 high school students. The data were collected through Cognitive Flexibility Scale, KIDCOPE, and EPOCH. It was found that cognitive flexibility was a significant predictor of active coping, negative coping and five EPOCH well-being variables. Cognitive flexibility positively affected active coping and five components of EPOCH well-being (engagement, perseverance, optimism, connectedness and happiness) while it affected avoidant coping negatively. The findings of the research showed that both active and negative coping played mediating roles between cognitive flexibility and EPOCH five-dimensional well-being variables. The practical implications for school teachers, limitations and further research for the researchers are presented in the study.
