累积生态风险对大学生运动拖延的影响

Influence of Cumulative Ecological Risk on University Students’Sports Delay

目的探讨累积生态风险对运动拖延的影响机制。方法利用相关分析法、回归分析法和Bootstrap检验法对903名大学生进行调查。结果累积生态风险、锻炼自我效能感、自我控制与大学生运动拖延四者之间有显著相关性(p<0.001)。多元回归分析结果显示,累积生态风险能正向预测大学生运动拖延(β=0.612,t=23.28,p<0.001),能负向预测锻炼自我效能感(β=-0.174,t=-5.490,p<0.001)。锻炼自我效能感在累积生态风险与大学生运动拖延之间存在部分中介效应,中介效应占比为8.7%。累积生态风险与大学生运动拖延的关系受自我控制的调节(β=-0.064,t=-1.924,p=0.014),说明被试自我控制水平越高,累积生态风险对大学生运动拖延的正向预测作用越弱。结论累积生态风险可以直接或通过锻炼自我效能感间接影响大学生的运动拖延。自我控制可以有效缓解由累积生态风险引发的大学生运动拖延水平。

Objective To explore the mechanism of cumulative ecological risk on exercise procrastination.Methods A survey of 903 university students was conducted using correlation analysis,regression analysis and Bootstrap test.Results There was a significant correlation between cumulative ecological risk,exercise self-efficacy,self-control and exercise procrastination among college students(p<0.001).Multiple regression analysis showed that cumulative ecological risk positively predicted exercise procrastination(β=0.612,t=23.28,p<0.001)and negatively predicted exercise self-efficacy(β=-0.174,t=-5.490,p<0.001).There was a partial mediating effect of exercise self-efficacy between cumulative ecological risk and exercise procrastination among college students,with a mediating effect of 8.7%.The relationship between cumulative ecological risk and exercise procrastination among college students was moderated by self-control(β=-0.064,t=-1.924,p=0.014),indicating that the higher the level of self-control of the subjects,the weaker the positive predictive effect of cumulative ecological risk on exercise procrastination among college students.Conclusion Cumulative ecological risk can directly or indirectly affect college students’exercise procrastination through exercise self-efficacy.Self-control can effectively alleviate the procrastination of college students'movement caused by accumulated ecological risks.
