大学生强化敏感性对网络游戏成瘾的影响：网络游戏动机的中介效应

Reinforcement Sensitivity of College Students Affects Their Online Game Addiction:The Mediating Effect of Motivations for Playing Online Games

目的：本研究为明确大学生强化敏感性对网络游戏成瘾的具体作用机制.方法：采用行为激活和抑制量表、网络游戏动机量表与网络游戏成瘾问卷对713名玩网络游戏的大学生进行测量.结果：①强化敏感性的行为抑制系统（BIS）、行为激活系统（BAS）与网络游戏动机和网络游戏成瘾呈显著正相关（r=0.30~0.58,P〈0.05）,网络游戏动机与网络游戏成瘾呈显著正相关（r=0.58,P〈0.01）;②BIS和BAS能显著预测网络游戏成瘾（t=3.71,5.75;P〈0.01）;③网络游戏动机在行为激活系统与网络游戏成瘾之间起中介作用（OR=0.47,P〈0.01,间接效应值为0.26,占总效应的59%）,而在行为抑制系统与网络游戏成瘾之间的中介作用不显著（OR=0.03,P=0.16）.结论：大学生强化敏感性的不同维度对其网络游戏成瘾作用有所差异,并且网络游戏动机在强化敏感性不同维度上的中介效应也有所差异.

Objective：To explore the relationship between reinforcement sensitivity,motivations for playing online games and online game addiction.Methods：A total of 713 college students playing online games were administrated to complete Behavioral Inhibition System and Behavioral Activation Scale （Chinese edition）,Motivations for Playing Online Game Scale and Online Game Addiction Scale.Results：The results were as follows：① The correlations among all variables were significant：BAS and BIS was positively correlated with motivations for playing games and online game addiction（r=0.30~0.58,P〈0.05）;Motivations for playing games was positively correlated with online game addiction（r=0.58,P〈0.01）.② Hierarchical regressions showed that BIS and BAS both emerged as significant pre-dictors of online game addiction（β=0.16,t=3.71,P〈0.01;β=0.25,t=5.75,P〈0.01）.③ The nonparametric bias-corrected percentile bootstrap method was used to further analyze the mediating effect,indicating that motivations for playing online games mediated the relationship between BAS and online game addiction（OR=0.47,P〈0.01;in-direct effect：0.26;percent of the total effect：59%）;however,it did not mediate the relationship between BIS and on-line game addiction（OR=0.03,P=0.16）.Conclusion：Reinforcement sensitivity of college students has different effect on the online game addiction,and online gaming motivation as the mediation effect on reinforcement sensitivity is different.
