This study investigated the effect of online social support on individual social self-efficacy and the underlying mechanism of social media use motivation with samples of college students using “Sina Weibo”, China’s equivalent of Twitter. Through the survey of 204 college students, a significantly positive correlation was found between online social support, social media use motivation and social self-efficacy. The “social support – social media use motivation – social self-efficacy” path varied according to different social support types: when social support was viewed as a whole, Weibo use moderated between social support and social self-efficacy — the impact of online social support on self-efficacy was not significant at a low Weibo use frequency while online social support would significantly prompt social self-efficacy at a high Weibo use frequency; when it came to the sense of belonging in social support, Weibo use served as a complete mediator between online social support and social self-efficacy — the sense of belonging promoted college students to use Weibo more, and ultimately improved their social self-efficacy. The findings are of theoretical and practical significance for understanding why people like to use social media and how the internet affects human psychology and behavior.

Key words: social media, Weibo, social self-efficacy, online social support


通过对使用新浪微博的204名大学生的调查, 发现线上社会支持、社交媒体使用和社交自我效能感之间显著相关, 它们之间的关系因社会支持类型的不同而各有特点: 把社会支持看成一个整体时, 社交媒体上的社交互动在线上社会支持对社交自我效能的影响中起调节作用, 随着社交媒体的社交互动增多, 线上社会支持对社交自我效能感的正性影响越来越显著; 而从线上社会支持的归属感维度讲, 社交媒体上的社交互动在线上社会支持和社交自我效能感之间起完全中介作用, 归属感促使大学生更多地在社交媒体上进行社交互动, 由此提升其社交自我效能感。研究结果可为理解人们为什么喜欢使用社交媒体以及线上行为如何影响线下心理与行为提供启示。
