Effects of Physical Exercise on College Students'Subjective Well-being:Chain Mediating Role of Perfectionism and Self-enhancement
In order to explore the relationship between physical exercise and subjective well-being,this study examines the chain mediating role between perfectionism and self-enhancement based on the elements of the self-system.The subjects were 951 college students(age=19.21±1.02 years old,male=515,female=436).The results show that:(1)there is a significant positive correlation between physical exercise and subjective well-being of college students(r=0.152).(2)In the chain mediation model,the total predictive effect of physical exercise on subjective well-being was 0.083 8,where the direct predictive effect was 0.0649 and the total indirect effect was 0.0189,both of which reach statistical significance.(3)The indirect influence of physical exercise on subjective well-being consists of negative mediation effect of perfectionism(effect value-0.015 8;effect proportion 18.85%),positive mediation effect of self-enhancement(effect value 0.032 6;effect proportion 38.90%)and positive interaction effect of the two(effect value 0.002 1;effect proportion 2.50%).(4)The chain mediating effect of perfectionism and self-enhancement is lower than that of their own independent mediating effect,and the differences are both statistically significant.It is therefore concluded that physical exercise has a predictive effect on the subjective well-being of college students.The mechanism of this effect includes the direct effect of physical exercise,the negative mediating effect of perfectionism,the positive mediating effect of self-enhancement and the chain mediating effect of both.Self-enhancement has a"buffering"effect on the negative mediating effect of perfectionism.The study suggests that the self-enhancement factors of college students should be used to reduce the negative effects of perfectionism,so as to provide theoretical basis for effectively enhancing the positive effects of physical exercise on subjective well-being.
