青少年“在线运动友谊网”在锻炼者图式影响健康促进生活方式中的调节效应

Moderating Effects of Adolescents'"Online Exercise Friendship"on Exerciser Schemas and Health Promotion Lifestyles

运用社会网络分析方法检验“在线运动友谊网”的结构(网络规模、网络密度、网络层级、网络约束)在自变量锻炼者图式和因变量健康促进生活方式中的调节效应。发现:①在主效应检验中,锻炼者图式正向影响因变量;网络层级和网络约束负向影响因变量,表明“在线运动友谊网”的结构扁平,小群体权力和影响力去中心化,并且网络结构洞多,对健康促进生活方式的预测更优。②在与锻炼者图式的交互效应检验中,网络密度正向影响因变量,网络约束负向影响因变量,即锻炼者图式水平相同时,网络密度高或网络约束低对健康促进生活方式的影响更显著。③以网络密度为代表的网络封闭和以网络约束为代表的结构洞在共存互补中呈现一种张力,在矛盾统一中影响青少年的健康促进生活方式。网络结构调节效应显著为在线小群体的体育与健康社会动员策略提供了经验数据和可能的理论依据。

Social network analysis was used to verify the moderating effect between the exerciser schema and the health promotion lifestyle of adolescents on the"online exercise friendship"network structure(including internet scale,density,hierarchy and constraint).The results showed that:①The main effect test showed that adolescent exerciser schema positively influenced exerciser's health promotion lifestyles.The"online exercise friendship"network hierarchy and network constraints negatively influenced the dependent variables,indicating that the network structure was flat,that the"power"and"influence"of small groups were decentered,and the network constraints were low,with many structural holes,which was an excellent prediction for the dependent variables.②In the interaction effect test of exerciser schema,network density positively affected the dependent variables and network constraint negatively affected the dependent variables.That is,when the level of exerciser schema was the same,a high network density or a low network constraint had a more significant effect on health promotion lifestyles.③Network closure represented by network density and network constraint represented by structural holes coexisted and complemented each other,affecting the dependent variable in contradiction and unity.The results of significant network structure moderation effects provide empirical data and a possible theoretical basis for social mobilization strategies for sport and health in online small groups.
