网络成瘾对大学生身体活动的影响:领悟社会支持的调节

Influence of Internet Addiction Disorder on Undergraduates’Physical Activities:A Moderating Effect of Perceived Social Support FAN Yuchuan

目的:探讨大学生网络成瘾、领悟社会支持、身体活动的现状特征及其内在影响机制。方法:修订青少年上网成瘾自评量表、领悟社会支持量表和国际身体活动量表(短版),以浙、沪、苏3省/直辖市为例,对938名大学生[男502人,女436人;年龄(19.76±2.142)岁]进行调查。结果:大学生能够领悟到中高程度的社会支持,其网络成瘾处于中等水平,但成瘾者占总体的31.34%,大学生身体活动处于中等水平,且性别差异有统计学意义(男生高于女生),网络成瘾者与非成瘾者差异也具有统计学意义(非成瘾者身体活动水平高于成瘾者);网络成瘾、领悟社会支持对大学生身体活动影响皆显著(P<0.001),分别解释了11.2%和5.7%的变异,而且,在网络成瘾与大学生身体活动的影响链上,领悟社会支持具备调节效应。结论:大学生能领悟到中高程度的社会支持,其身体活动处于中等水平,并且,男生身体活动水平显著高于女生;大学生网络成瘾倾向处于中低水平,且网络成瘾者的身体活动水平显著低于非成瘾者。网络成瘾是大学生身体活动的制约因素,领悟社会支持是身体活动的激励因素;领悟社会支持能够调节网络成瘾对大学生身体活动的消极影响。调节效应关系的建立,在一定程度上解释了网络成瘾影响大学生身体活动的内在机制,可为引导大学生建立健康生活方式提供参考。

Objective:Explored the status quo of undergraduates’internet addiction disorder(IAD),perceived social support(PSS)and physical activity(PA),and their internal influence mechanism.Methods:The Diagnostic Scale for Internet Addiction Disorder,Perceived Social Support Scale,and International Physical Activity Questionnaire-Short Form,were used to investigate on 938 undergraduates(aged=19.76±2.142;male=502,female=436)in Zhejiang Province,Shanghai and Jiangsu Province as examples.Furthermore,the Process(Version 2.16)of the Bootstrap program plug-in was used to analyze the indirect influence of IAD on undergraduates’PA.Results:Undergraduates could perceive the medium-high level of social support,and their IAD was at a low level,but the man who Internet addicts accounted for 31.34%of the total.Undergraduates’PA was at a medium level.Moreover,their PA level had the significant difference in gender,and had also the significant difference between internet addicts and non-internet addicts.The significant effects directly,IAD and PSS on undergraduates’PA(P<0.001),and these two antecedent factors mutation rates were 11.2%and 5.7%,respectively.In addition,the moderating effect of PSS was significant that in the influence chain of undergraduates’IAD and PA.Conclusions:For undergraduates,the perceived social support is at a medium-high level.Their PA is at a medium level,moreover,male has the significantly higher PA level than female.The IAD is at a low level,but the man who Internet addicts accounted for 31.34%of the total.Furthermore,The internet addicts have significantly lower levels of PA than non-addicts.The IAD is a constraining factor for undergraduates’PA,while the PSS is a motivating factor for undergraduates’PA.Moreover,the PSS could regulate the negative impact of IAD on undergraduates’PA.To a certain extent,the construction of the moderating effect relationship explained the internal mechanism of the influences of undergraduates’internet addiction disorder on physical activity,and it could provide some reference for developing a healthy lifestyle for undergraduates.
