微信使用强度与大学生自尊之间的关系:上行社会比较和好友亲密度的作用

为探讨微信使用强度与大学生自尊的关系，采用微信使用强度问卷、上行社会比较问卷、好友亲密度量表和自尊量表，对330名大学生的微信经历和自尊情况进行问卷调查。结果发现：（1）微信使用强度与自尊显著负相关，且上行社会比较在其中起显著中介作用；（2）好友亲密度在上行社会比较与自尊之间起调节作用：在好友亲密度较低的情况下，上行社会比较与自尊显著负相关；在好友亲密度较高时，上行社会比较与自尊相关不显著。结果提示，微信使用程度越强，上行社会比较越多，大学生的自尊水平越低，但是网上亲密的好友关系可以缓解这一关系。

The Relationship between the Intensity of WeChat Use and College Students' Self-esteem: The Role of Upward Social Comparison and Closeness to Friends

In order to explore the relationship between the intensity of WeChat use and college students' self-esteem and the mechanism underlying this relationship, 330 undergraduates' experiences in WeChat use and their self-esteem were surveyed using a series of questionnaires to test a moderated mediation model. The results showed that:(1) the intensity of WeChat use was significantly negatively related to college students' self-esteem, which was mediated significantly by their upward social comparison; (2) closeness to friends played a moderating role in the relationship between upward social comparison and self-esteem:when the levels of closeness to friends were lower, higher levels of upward social comparison were significantly associated with lower levels of self-esteem, whereas no significant relationship was found between upward social comparisons and self-esteem when higher levels of closeness to friends. The results suggest that more upward social comparison during WeChat use is a risk factor of lower self-esteem among college students, but high level of closeness to online friends can alleviate this risk.
