目的:探究主动性社交网站使用对生命意义感的影响及其作用机制。方法:采用主动性社交网站使用问卷、拥有生命意义感量表、积极情绪量表、社会比较倾向量表和自我概念清晰性问卷对大学生进行问卷调查,共收回有效问卷1018份。结果:(1)主动性社交网站使用显著正向预测生命意义感。(2)积极情绪在主动性社交网站使用和生命意义感之间的中介作用显著,社会比较在两者之间的中介作用不显著。(3)自我概念清晰性水平既正向调节主动性社交网站使用对积极情绪和社会比较的影响,也正向调节积极情绪和社会比较对生命意义感的影响。(4)自我概念清晰性水平正向调节积极情绪和社会比较在主动性社交网站使用和生命意义感之间的中介效应。结论:主动性社交网站使用能直接预测生命意义感,也能通过积极情绪的中介作用影响生命意义感;在高自我概念清晰性水平下,还能通过社会比较的中介作用影响生命意义感。

Objective:To explore the association and mechanism of the relationship between active use of social network site(AUSNS)and meaning in life(MIL).Methods:A survey research method was used in the form of the scales for the AUSNS,presence of MIL,positive affects(PA)and social comparison(SC)as well as self-concept clarity(SCC)which were administered to undergraduates.1018 valid questionnaires were taken back.Results:(1)AUSNS positively predicted MIL.(2)PA had a significant mediating effect between AUSNS and MIL,while SC didn’t.(3)SCC moderated not only the effects of AUSNS on PA and SC,but also the effect of PA and SC on MIL.(4)SCC positively moderated the mediating effect of PA and SC between AUSNS and MIL.Conclusion:AUSNS not only directly predicts MIL,but also affects MIL through the mediating effect of PA.Mediating effect of SC between AUSNS and MIL also is significant when SCC is at high level.
