大学生社交网站使用与依赖:积极自我呈现的中介效应与关系型自我构念的调节效应
Social Network Sites Use and Addiction among College Students: The Mediating Role of Positive Self-presentation and the Moderating Role of Relational-interdependent Self-construal

采用问卷法对658名具有社交网站使用经验的大学生进行调查，考察大学生社交网站使用与依赖的关系、积极自我呈现的中介作用以及关系型自我构念的调节作用。结果发现：（1）社交网站使用能显著正向地预测大学生社交网站依赖；（2）积极自我呈现在社交网站使用与依赖的关系中起部分中介作用；（3）积极自我呈现的中介作用受到关系型自我构念的调节。具体来说，相对于高关系型自我构念的大学生，低关系型自我构念大学生的社交网站使用更多地通过积极自我呈现影响其社交网站依赖。
This study investigated the relationships between social network sites use (SNS use)and social network sites addition (SNS addition), and the mediating effect of positive self-presentation as well as the moderating effect of relational-interdependent self-construal(RISC). Based on cluster sampling, 658 college students who have used SNS for more than three months were recruited to participate in this study. The results indicated that:(1) SNS use significantly positively predicted SNS addiction; (2) positive self-presentation played a partial mediating role between SNS use and SNS addiction; (3) the mediation was moderated by RISC, such that the indirect effect was much stronger for college students with low RISC relative to those with high RISC.
