社交网站使用对大学生自尊的影响:线上好友数量的中介作用和性别的调节作用

The Effect of Social Network Sites Use on Self-esteem in College Students:Mediating of the Number of Online Friends and Moderating of Gender

社交网站已经成为当代大学生日常生活的一部分,使用社交网站交友是一种普遍现象,但社交网站使用和自尊之间的关系尚不清楚。为探究社交网站使用、线上好友数量和自尊之间的关系,对418名大学生展开了问卷调查。结果发现:(1)社交网站使用、线上好友数量和自尊两两之间呈显著正相关;(2)线上好友数量在社交网站使用对自尊的影响中具有完全中介作用;(3)社交网站使用对自尊的正向预测作用受到性别的调节,仅在女生中表现出来。社交网站使用通过线上好友数量的完全中介作用对大学生的自尊产生积极影响,但仅对女生的自尊具有正向预测作用。

In recent years, social network sites （SNS） are more and more popular among the Chinese, especially in college students. As a new communication instrument, SNS provides better opportunities for undergraduates to build and maintain a network of online friends, which has a very significant effect on college students＇ psychological development. However, the association between SNS use and self-esteem is still unclear. The aim of this study was to find the effect of SNS use on self-esteem and the further exploration was to investigate the mediating effect of the number of online friends and the gender difference between them. Totally 418 subjects were adopted in the data analysis model. The results indicated that ： （ 1 ） SNS use, self-esteem and the number of online friends were significantly positively correlated with each other; （2） the effect of SNS use on self-esteem was through the complete mediating role of the number of online friends; （3） the effect of SNS use on self-esteem was moderated by gender, the positive prediction of SNS use on self-esteem was only found in female. From the present study we can draw a conclusion that SNS use was beneficial to self-esteem through the complete role of the number of online friends, but there was a gender difference between them, suggesting that the female Chinese college students may benefit more than the male ones.
