This study aimed to explore the interactions among shyness, peer relationships, and Internet addiction. A tracking design was used to examine the responses of 387 seniors in two vocational high schools twice. The cross-lagged results showed that (1) shyness at time T1 significantly and positively predicted Internet addiction at time T2 (β = 0.49, p < 0.001) and negatively predicted peer relationships at T2 (β = −0.27, p < 0.001). (2) Peer relationships at T1 significantly and negatively predicted shyness at T2 (β = −0.30, p < 0.001) and Internet addiction at T2 (β = −0.17, p < 0.001). Other lagged effects were not significant. (3) Further mediating effects test results indicated that peer relationships partially mediated the effect of shyness on Internet addiction. Overall, the relationship between shyness and Internet addiction and that between peer relationships and Internet addiction were not bidirectional. Meanwhile, the relationship between shyness and peer relationships had a dynamic bidirectional effect.

这项研究旨在探讨害羞、同伴关系和网络成瘾之间的相互作用。使用跟踪设计对两所职业高中的 387 名高年级学生的回答进行了两次检查。交叉滞后结果表明（1）时间T1的害羞在时间T2显着和积极地预测网络成瘾（β  = 0.49，p <0.001）并且在T 2 消极预测同伴关系（β  = -0.27，p  <0.001） . (2) T1时的同伴关系显着负向预测T 2 时的害羞 ( β  = −0.30, p< 0.001）和T 2 时的网络成瘾（β  = −0.17，p  < 0.001）。其他滞后效应不显着。(3) 进一步的中介效应检验结果表明，同伴关系部分地中介了害羞对网络成瘾的影响。总的来说，害羞与网络成瘾之间的关系以及同伴关系与网络成瘾之间的关系不是双向的。同时，害羞与同伴关系之间的关系具有动态双向效应。
