大学生网络使用问题形成机制及教育干预研究：基于生态系统和风险累积视角

大学生是各种网络使用问题的易感群体。他们在认知及个性社会性发展方面和青少年存在差异，也面临不同的环境和挑战。因而其网络使用问题形成机制可能和受研究者重点关注的青少年有所不同。同时，不同类型的网络使用问题彼此间具有内在联系，把握核心问题和关键路径有助于多种网络使用问题的综合解决。然而已有研究并没有回答这些问题。为填补这一空白，本项目将在风险累积模型和生态系统理论框架下，综合利用质性访谈、横断跨层研究、交叉滞后研究、纵向追踪研究等方法，在不同发展阶段网络使用问题异同比较的基础上，首先分析大学生网络使用问题的初始状态和发展过程，随后探究不同网络使用问题间的内在联系、形成机制和的动态变化，最后验证所发现的核心问题及关键路径的生态效度。在具体研究内容上，本项目拟开展三个研究（共6个子研究），依次探讨学生网络使用问题跨发展阶段变迁、大学生网络使用问题间内在联系和形成机制以及教育干预的实际效果。

Undergraduates are susceptible to developing problems in Internet use. They differ from adolescents in cognitive and personal/social development. And they face different environments and challenges. Therefore, the underlying influencing mechanisms of problems in Internet use may be different from that of adolescent. At the same time, there are some connection between different types of problems in Internet use. Solving the core problems and intervention of key paths may be helpful to solve various problems in Internet use comprehensively. However, the previous studies have not answered these questions. In order to fill this gap, the present project attempts to investigate the interrelationships, development, mechanisms and intervening effects of problems in Internet use taking the perspective of the Cumulative Risk Model and Ecological Systems Theory. The present project will combine the quantitative research and the qualitative research, including interview, multilevel cross-sectional study, cross-lagged panel study and longitudinal study. This project includes three studies (six sub-studies), in which we will investigate development of problems in Internet use, their interrelationships and influencing mechanism, and the effects of intervening the core problem on other problems, respectively.
