累积生态风险对大学生运动拖延影响:基于自我控制的中介效应和锻炼氛围的调节效应

The Impact of Cumulative Ecological Risk on College Students’Exercise Procrastination:the Mediating Effect of Self-Control and the Moderating Effect of Exercise Atmosphere

目的:探究累积生态风险与大学生运动拖延间的内在关系,为大学生形成健康的体育生活方式提供理论参考。方法:采用累积生态风险量表、自我控制量表、锻炼氛围量表和运动拖延量表对江西省五所高校903名大学生进行调查,验证自我控制的中介效应和锻炼氛围的调节效应。结果:(1)累积生态风险、自我控制、锻炼氛围和大学生运动拖延之间存在显著相关(P<0.01);(2)累积生态风险能显著正向预测大学生运动拖延(β=0.612**),能负向预测大学生自我控制(β=-0.342**),当累积生态风险和自我控制共同预测大学生运动拖延时,R?解释力提高且路径系数显著,表明自我控制存在部分中介效应。(3)锻炼氛围调节了累积生态风险与大学生自我控制的路径(β=-0.164**,t=-6.250,P=0.000)。结论:累积生态风险对大学生运动拖延有正向预测作用,自我控制是累积生态风险影响大学生运动拖延的中介变量,锻炼氛围是一个调节变量。

Objective:To study the impact of cumulative ecological risk on college students'exercise delay,and to investigate the mediating effect of self-control and the regulating effect of exercise atmosphere.Methods:The cumulative ecological risk scale,self-control scale,exercise atmosphere scale and exercise procrastination scale were used to survey 903 college students from five universities in Jiangxi Province,and the structural equation model was constructed by Amos to fit the data.Results:(1)There is a significant correlation between accumulating ecological risks,self-control,exercise atmosphere and delay of college student motion(P<0.01).(2)Cumulative ecological risk can significantly positively predict college students’movement delay(β=0.612**),and negatively predict college students’self-control(β=-0.342**),and self-control has some mediating effects.When accumulating ecological risks and self-control joint forecasting college student movement delay,the R?interpretation force is increased and the path coefficients are significant,indicating that there is some intermediary effects in self-control.(3)The exercise atmosphere regulates the path of cumulative ecological risk and college students'self-control(β=-0.164**,t=-6.250,P=0.000).Conclusion:Cumulative ecological risk has a positive predictive effect on college students’exercise delay.Self-control is the mediating variable of cumulative ecological risk affecting college students’exercise delay.Exercise atmosphere is a moderating variable.
