网络成瘾与大学生在校身体活动的关系研究

Influence of Internet Addiction Disorder on Undergraduates’Physical Activities in School

目的:运用纵向研究——交叉滞后研究设计,探讨网络成瘾与大学生在校身体活动的因果关系。方法:采用青少年上网成瘾自评量表和国际身体活动量表(短版),对上海市8所高校的604名大学生(52.81%男生)进行为期4个月、两阶段的追踪问卷调查。结果:大学生网络成瘾的性别差异不显著(P>0.05),但在校身体活动的性别差异显著(男生优于女生),且网络成瘾者与非网络成瘾者的在校身体活动水平也存在显著差异(成瘾者低于非成瘾者);大学生网络成瘾与在校身体活动具有跨时间稳定的负相关(P<0.01);交叉滞后分析显示,前测(T_1)网络成瘾对后测(T_2)在校身体活动的影响显著(P<0.001),前测(T_1)在校身体活动对后测(T_2)网络成瘾影响显著(P<0.05),且前者的影响效应大于后者,网络成瘾与在校身体活动交叉滞后效应的性别差异不显著。结论:大学生在校身体活动具有性别差异,在网络成瘾者与非成瘾者间也存在差异;大学生网络成瘾与在校身体活动存在因果关系,其中网络成瘾是大学生在校身体活动的原因变量,且网络成瘾对大学生在校身体活动的影响具有性别一致性。交叉滞后模型的建构,在一定程度上解释了网络成瘾与大学生在校身体活动的内在关联,可为改善大学生身体活动水平提供一定参考。

Objective:Explored the causal relationship between undergraduates’internet addiction and physical activity in school used the cross-lagged research design of longitudinal study.Methods:Used the Diagnostic Scale for Internet Addiction Disorder(DSFIAD),and International Physical Activity Questionnaire-Short Form(IPAQ-SF),this paper made a four months,two-stage follow-up investigation on 604 undergraduates(53.81%boys;M±SD=19.33±1.974 years)from 8 universities in Shanghai.Results:The gender difference in undergraduates’internet addiction was not significant,while,the gender difference in their physical activity was significant(male was better than female).Moreover,between internet addicts and non-internet addicts,there was also significant difference in undergraduates’physical activity level in school(addicts were lower than non-addicts).There was a trans-temporal-stable significant negative correlation between undergraduates’internet addiction and physical activity in school(P<0.01).The cross-lagged analysis revealed that,for undergraduates,the significant negative effects,the internet addiction of test-1 on the physical activity of test-2(P<0.001),and the physical activity of test-1 on the internet addiction of test-2(P<0.05).Moreover,the influence effect of the former was greater than that of the latter.Conclusion:There are differences such as gender,internet addicts and non-addicts in undergraduates’school physical activity.There is a causal relationship between undergraduates’internet addiction and physical activity in school.Among them,the internet addiction is the cause variable of undergraduates’physical activity in school.Moreover,the influence of internet addiction on undergraduates’physical activities in school have the characteristics of gender consistency.To a certain extent,the construction of the cross-lagged model explained the internal relationship between internet addiction and undergraduates’physical activity in school,and it could provide some reference for improving the level of physical activity for undergraduate.
