摘要
目的探讨大学生锻炼身份认同与体育活动的关系,以及锻炼意向与锻炼计划的链式中介作用。方法采用锻炼身份认同量表、锻炼意向量表、锻炼计划量表和体育活动等级量表,对2452名在校大学生进行横断面调查,剔除324套无效问卷,最终获得有效问卷2128套。采用SPSS 27.0及Mplus 8.3软件对采集的数据进行统计处理并建立结构方程模型。结果偏相关分析结果表明,控制性别、年级和人口学变量后,大学生锻炼身份认同[(38.80±11.55)分]、锻炼意向[(14.28±3.61)分]、锻炼计划[(25.61±9.21)分]与体育活动[(23.25±21.33)分]四个变量相互之间存在正相关(r=0.58~0.74,均P<0.05)。锻炼意向和锻炼计划在大学生锻炼身份认同与体育活动间分别起部分单独中介作用,中介效应为0.39(95%CI=0.32~0.46),0.07(95%CI=0.04~0.11),锻炼意向和锻炼计划的链式中介作用为0.06(95%CI=0.04~0.09)。结论锻炼身份认同不仅能直接影响大学生体育活动,还可以通过锻炼意向与锻炼计划两个中介变量间接影响大学生体育活动。
Objective To explore the relationship between college students'exercise identity and physical exercise,as well as the chain mediating role of exercise intention and exercise plan.Methods Using the exercise identity scale,exercise intention scale,exercise plan scale and physical exercise rating scale,a cross-sectional survey was conducted on 2452 college students.After 324 sets of invalid questionnaires were excluded,a total of 2128 sets of valid questionnaires were obtained.SPSS 27.0 and Mplus 8.3 software were used to statistically process the collected data and establish structural equation model.Results The results of the partial correlation analysis showed that after controlling for the demographic variables of gender and grade,the four variables of college students'exercise identity(38.80±11.55),exercise intention(14.28±3.61),exercise plan(25.61±9.21),and physical exercise(23.25±21.33)were positively correlated with each other(r=0.58-0.74,all P<0.05).Exercise intention and exercise plan acted as partial individual mediators between exercise identity and physical exercise in college students,respectively,with mediating effects of 0.39(95%CI=0.32-0.46),0.07(95%CI=0.04-0.11),and chain mediating effect of exercise intention and exercise plan of 0.06(95%CI=0.04-0.09).Conclusion Exercise identity can not only directly influence college students'physical exercise,but also indirectly influence college students'physical exercise through the two mediating variables of exercise intention and exercise plan.
