目的:分析体育锻炼与女大学生抑郁、社会支持之间的关系,研究社会支持三纬度(主观支持、客观支持、支持利用度)在体育锻炼与抑郁之间的多重中介作用.方法:抽取某高校300名女大学生,采用《体育活动等级量表》、《抑郁自评量表》、《社会支持评定量表》对其进行调查;利用层级回归与偏差矫正的非参数百分位Bootstrap方法对主观支持、客观支持、支持利用度的多重中介作用进行检验.结果:多重中介作用的总体效应显著,其效应量占总效应量的56％,而体育锻炼对抑郁的直接作用不显著;多重中介作用中,主观支持、支持利用度的中介作用效应显著,而客观支持的中介作用效应不显著,它们的中介效应量分别占间接效应的47.3％、36.6％、16.1％.结论:社会支持在体育锻炼影响女大学生抑郁中起中介作用,其中,起主要中介作用的是主观支持、支持利用度两个纬度.“,”Objective To explore the relation among physical exercise,depression among female college students and social support,and the multiple mediation effect of three dimensions of social support between physical exercise and depression.Methods A total of 300 female college students were selected and investigated using the physical activity rating scale-3 (PARS-3),self-rating depression scale (SDS) and social support rating scale(SSRS).The multiple mediation effects of the subjective support,objective support and support utilization were tested using the hierarchical regression and the bias-corrected non parametric percent Bootstrap method.Results The overall effect of multiple mediation was significant,accounting for 56％ of the total effect,while the direct effect of physical exercise on depression was not significant.As for the multiple mediation effects,the mediation effect of subjective support and support utilization was significant,while that of the objective support was not.Their mediation effect accounted for 47.3％,36.6％ and 16.1％ of the indirect effect respectively.Conclusion Social support has a mediation effect between physical exercise and depression among female college students,and the subjective support and support utilization are the main mediation factors.
