大学生网络交往与网络利他行为的关系:自尊与公我意识的作用

以湖北湖南三所高校大一至大四416名全日制大学生为被试，采用《大学生网络交往行为量表》、《自尊量表》、《公我意识量表》和《大学生网络利他行为量表》，对大学生的网络交往、自尊、公我意识以及网络利他行为的情况进行调查，探讨自尊是否在网络交往和网络利他行为之间起中介作用，以及这个过程是否受到公我意识的调节。结果显示：（1）网络交往对网络利他行为具有正向预测作用；（2）自尊在网络交往和网络利他行为间起部分中介作用；（3）自尊的中介效应受到公我意识的调节，即在高公我意识水平下，自尊能正向影响个体的网络利他行为；在低公我意识水平下，自尊对网络利他行为的影响不显著。研究结果有助于揭示大学生网络利他行为的形成机制，对大学生网络利他行为的干预有一定的启示意义。

Online Social Behavior and Online Altruistic Behavior: The Role of Self-esteem and Public Self-consciousness

The present study examined whether self-esteem mediated the relationship between online social behavior and online altruistic behavior, and whether this mediating process was moderated by public self-consciousness. A total of 416 college students (mean age=20.12, SD=1.64) from three universities in Hubei province and Hunan province completed anonymous questionnaires, which included College Students' Online Social Scale, Rosenberg Self-esteem Scale, Public Self-Consciousness Scale and Online Altruistic Behavior Scale. The results showed that:(1)Online social behavior positively predicted to online altruistic behavior; (2) Self-esteem played a partial mediating role in the association of online social behavior and online altruistic behaviors; (3) The effect of self-esteem on online altruistic behaviors was moderated by public self-consciousness, with the effect being stronger for students with a high level of public self-consciousness. Limitations and implications for future research are discussed.
