School bullying is a destructive behaviour common among adolescents that can sometimes escalate to criminal activity. This study aimed to examine the association between four types of school bullying (i.e., physical, verbal, relational, and cyber) and murderous ideation and behaviours (i.e., ideation, plans, preparation, and attempts) among adolescent students.
Data were collected from 5726 middle and high school students using self-administered questionnaires in December 2013. The participants were selected using a 3-stage random cluster-sampling strategy. The participants were asked about the frequency of their bullying experiences in the past two months and the frequencies of their murderous ideation and behaviours in the past six months. Multivariate logistic regressions were performed to explore the association between school bullying and murderous ideation and behaviours.
Each type of school bullying perpetration was associated with murderous ideation and behaviours, as was each type of bullying victimization. Students who experienced more types of school bullying perpetration and victimization were more likely to report murderous ideation and behaviours. Moreover, the number of types of bullying perpetration and victimization had a dose-response association with murderous ideation and behaviours (aOR min = 1.45, aOR max = 2.72), as did the frequency of involvement in bullying perpetration and victimization (aOR min = 1.33, aOR max = 2.00). Being a bully-victim was a risk factor for murderous ideation and behaviours (aOR min = 3.88, aOR max = 7.24).
Each type of school bullying was associated with an increased risk for murderous ideation and behaviours among adolescents. Dose-response relationships between the frequency of bullying and number of bullying types experienced and murderous ideation and behaviours were found in this study. Future studies are warranted to confirm our findings and explore the mechanisms underlying the relationship between school bullying and murderous ideation and behaviours.
校园欺凌是一种在青少年中普遍存在的破坏性行为，有时会升级为犯罪行为。本研究旨在探讨四种类型的校园欺凌（即身体欺凌、言语欺凌、关系欺凌和网络欺凌）与青少年学生的杀人意念和行为（即意念、计划、准备和尝试）之间的关联。
2013 年 12 月，采用 3 阶段随机整群抽样策略，使用自填式问卷从 5726 名中学生和高中生中收集数据。参与者被问及过去两个月中欺凌经历的频率以及过去六个月中杀人意念和行为的频率。采用多变量 logistic 回归探讨校园欺凌与杀人意念和行为之间的关联。
每种类型的欺凌行为都与杀人意念和行为有关，每种类型的被欺凌也都与杀人意念和行为有关。经历过更多类型的欺凌行为和被欺凌的学生更有可能报告杀人意念和行为。此外，欺凌行为和被欺凌的类型越多，与杀人意念和行为的关联就越强（aOR 最小=1.45，aOR 最大=2.72），参与欺凌行为和被欺凌的频率也与杀人意念和行为的关联越强（aOR 最小=1.33，aOR 最大=2.00）。欺凌者-受害者是杀人意念和行为的一个危险因素（aOR 最小=3.88，aOR 最大=7.24）。
每种类型的校园欺凌都与青少年杀人意念和行为的风险增加有关。本研究发现，欺凌频率和经历的欺凌类型与杀人意念和行为之间存在剂量反应关系。未来的研究有必要证实我们的发现，并探讨校园欺凌与杀人意念和行为之间关系的机制。
