大学生网络社会支持与网络利他行为的关系:一个有调节的中介模型
The Relationship between Online Social Support and Online Altruistic Behavior of College students: A Moderated Mediating Model

以武汉三所高校大一至大四491名全日制大学生为被试，采用《大学生网络社会支持问卷》、《自尊量表》、《网络空间人际信任问卷》和《大学生网络利他行为量表》进行问卷调查，对大学生的网络利他行为、网络社会支持、自尊以及网络人际关系情况进行调查，探讨自尊是否在网络社会支持和网络利他行为之间存在中介作用，以及这个过程是否受到网络人际信任的调节。结果显示： （1）大学生网络社会支持能够显著正向预测网络利他行为；（2）自尊在网络社会支持和网络利他行为的关系之间起部分中介作用；（3）网络人际信任在网络社会支持与自尊之间起调节作用。即在高网络人际信任水平下，网络社会支持能正向影响个体自尊水平；在低网络人际信任水平下，网络社会支持对个体自尊的影响不显著。

The results showed that:(1) Online social support positively predicted to online altruistic behavior;(2) Self-esteem played a partial mediating role in the association of online social support and online altruistic behavior;(3) The mediating effect of self-esteem was moderated by online interpersonal trust. In the high level of online interpersonal trust, self-esteem partially mediated the associations of online social support and online altruistic behavior; but not in the low level of online interpersonal trust.
