Aim: Identify and systematically review cohort studies examining the association between cyberbullying (CB) and suicidal ideation, attempted suicide, self-harm, and nonsuicidal self-injury (NSSI). Methods: Systematic literature review following PRISMA guidelines. Searches for relevant literature were conducted in Scopus, Web of Science, PubMed, PsyINFO, CINAHL, Embase, and Cochrane up until July 2023. Cohort studies were included that provided information regarding the association between CB and different dimensions pertaining to self-injurious thoughts and behaviors (SITB) separately. Gathered information included data on study characteristics, sample characteristics, prevalence, and associations between CB and variables pertaining to SITB. Findings were synthesized, and grouping studies as a function of the outcome variable was analyzed. Results: A total of 19 studies were included. Suicidal ideation was analyzed in 11 studies, with the majority (n = 8) reporting statistically significant positive associations (aOR = 1.88 [1.08, 3.29], β = 0.08 to 0.47). Only a single study conducted independent analysis of attempted suicide, finding a statistically significant association (aOR 1.88 [1.08, 3.29]). Outcomes regarding the self-harm variable were equivocal, with only two out of five studies finding a statistically significant association and one of these, which conducted a gender differentiated analysis, only finding a significant association in females. Studies that considered the NSSI dimension were also inconclusive, with only a limited number of studies (n = 5) producing contradictory outcomes. Conclusion: There is a need to continue exploring the relationship between CB and different dimensions within the spectrum of SITB through longitudinal studies. It is recommended that analyses adopt a new perspective in which short-term follow-up is prioritized or individualized follow-up periods are considered, given the rapidly changing nature of suicidal tendencies. It would be interesting to analyze the frequency, persistence, or severity of CB events and broaden research to include all age ranges. Special attention should also be given to potential gender differences and possible mediators or moderators.

网络欺凌和自杀行为、自残和非自杀性自残：纵向研究的系统评价。


目的：确定并系统回顾队列研究，检查网络欺凌 （CB） 与自杀意念、自杀未遂、自残和非自杀性自残 （NSSI） 之间的关联。方法：遵循 PRISMA 指南的系统文献综述。截至 2023 年 7 月，在 Scopus、Web of Science、PubMed、PsyINFO、CINAHL、Embase 和 Cochrane 中检索了相关文献。纳入了队列研究，这些研究分别提供了有关 CB 与自伤思想和行为 （SITB） 相关不同维度之间关联的信息。收集的信息包括有关研究特征、样本特征、患病率以及 CB 与 SITB 相关变量之间的关联的数据。综合研究结果，并分析作为结果变量函数的分组研究。结果： 共纳入 19 项研究。在 11 项研究中分析了自杀意念，其中大多数 （n = 8） 报告了具有统计学意义的正相关 （aOR = 1.88 [1.08， 3.29]，β = 0.08 至 0.47）。只有一项研究对自杀未遂进行了独立分析，发现存在统计学意义的关联 （aOR 1.88 [1.08， 3.29]）。关于自我伤害变量的结果是模棱两可的，五项研究中只有两项发现具有统计学意义的关联，其中一项进行性别差异化分析的研究，仅在女性中发现显着关联。考虑 NSSI 维度的研究也尚无定论，只有有限数量的研究 （n = 5） 产生了相互矛盾的结果。结论： 有必要通过纵向研究继续探索 CB 与 SITB 谱中不同维度之间的关系。 鉴于自杀倾向的快速变化，建议分析采用新的视角，优先考虑短期随访或考虑个体化随访。分析 CB 事件的频率、持久性或严重程度并扩大研究范围以包括所有年龄范围会很有趣。还应特别注意潜在的性别差异和可能的调解人或主持人。
