Objective:To investigate the mediating roles of perceived social support and relative deprivation in the relationships between life events and Internet addiction among Chinese college students.Methods:Totally 413 college students (200 males and 213 females,aged 16-21 years),completed the Relative Deprivation Questionnaire,Adolescent Self-Rating Life Events Check List,Perceived Social Support Scale and Chinese Internet Addiction Scale Revised to measure the level of relative deprivation,life events,perceived social support and Internet addiction.The Bollen-Stine of structural equation modeling and Bootstrap were used to test the mediating effect of perceived social support and relative deprivation on the relationship between life events and Internet addiction.Results:The scores of PSSS were negatively correlated with the scores of ASLEC,RDQ,and CIAS-R (r=0.11-0.36,Ps ＜0.05).The scores of ASLEC,RDQ,and CIAS-R were positively correlated with each other (r=0.14-0.23,Ps ＜ 0.01).Path analyses showed that the ASLEC scores were not associated with the CIAS-R scores directly (β =0.11,P ＞0.05),but indirectly through the mediating roles of the scores of PSSS and RDQ and the chain mediating effect of them among Chinese college students.The structural equation model could be accepted by Bollen-Stine Bootstrap (P ＜0.01).The confidence interval from Bootstrap output of the mediating effects of the scores of PSSS and RDQ and the chain mediating effect of them were (0.010,0.103),(0.002,0.032) and (0.005,0.061) respectively.Conclusion:It suggests that life events could not directly affect Internet addiction,but indirectly lead to Internet addiction through reducing perceived social support and increasing relative deprivation.%目的:探索大学生领悟社会支持和相对剥夺感在生活事件与网络成瘾关系中的中介作用.方法:选取山东省某高校413例大学生(男200例,女213例,年龄16～21岁),采用相对剥夺感问卷(RDQ)、青少年生活事件量表(ASLEC)、领悟社会支持量表(PSSS)和网络成瘾量表(CIAS-R)分别对大学生相对剥夺感、生活事件、领悟社会支持和网络成瘾水平进行测量,采用结构方程模型的Bollen-Stine解靴带法和Bootstrap法对领悟社会支持和相对剥夺感在生活事件与网络成瘾间的中介作用进行检验.结果:相关分析显示,PSSS得分与ASLEC得分、RDQ得分和CIAS-R得分分别呈负相关(r=-0.11～-0.36,Ps＜0.05),ASLEC得分、RDQ得分和CIAS-R得分之间呈两两正相关(r=0.14 ～0.23,Ps＜0.01);中介效应分析显示,ASLEC得分对CIAS-R得分的直接通径无统计学意义(β=0.11,P＞0.05),PSSS与RDQ得分在ASLEC与CIAS-R得分之间起完全中介作用,模型的Bollen-Stine Bootstrap P值为0.003,PSSS和RDQ得分的中介作用以及两者的链式中介作用的Bootstrap输出的95％可信区间分别为(0.010,0.103)、(0.002,0.032)和(0.005,0.061).结论:本研究提示生活事件可能会降低个体领悟社会支持,增强相对剥夺感,间接促进个体网络成瘾的产生.
