To understand the development of cyber aggression during adolescence, it is important to consider the temporal variability of its potential predictors. This study uses a four-wave survey to investigate how changes in peer norms, parental norms, and parental communication are associated with two-year trajectories of online peer aggression. The sample includes 1521 Swiss middle school students (M_age T1 = 11.54, SD = 0.40; 48% female). The results showed that over time a better parental communication quality and anti-aggression norms predicted lower rates and slower development of cyber aggression. Moreover, parental variables emerged as a quite stable deterrent of aggressive conduct. Although entrance into adolescence is characterized by the rise of peer influence, results from this study suggest that parents maintain an important protective role.

要了解青春期网络攻击的发展，重要的是要考虑其潜在预测因素的时间可变性。本研究使用四波调查来调查同伴规范、父母规范和父母沟通的变化如何与在线同伴攻击的两年轨迹相关联。样本包括 1521 名瑞士中学生（M_年龄T1 = 11.54，SD = 0.40；48% 女性）。结果表明，随着时间的推移，更好的父母沟通质量和反攻击规范预示着网络攻击的发生率较低且发展较慢。此外，父母变量成为攻击性行为的一种相当稳定的威慑力量。尽管进入青春期的特点是同伴影响力的增加，但这项研究的结果表明，父母保持着重要的保护作用。
