b.ckground: In recent years, online trolling has garnered signif.cant attention due to its detrimental ef.ects on mental health and social well-b.ing. The current study examined the inf.uence of.peer victimization on adolescent online trolling b.havior, proposing that hostile attrib.tion b.as mediated this relationship and that trait mindf.lness moderated b.th the direct and indirect ef.ects. Methods: A total of.833 Chinese adolescents completed the measurements of.peer victimization, hostile attrib.tion b.as, trait mindf.lness, and online trolling. Moderated mediation analysis was perf.rmed to examine the relationships b.tween these variab.es. Results: Af.er controlling f.r gender and residential address, the study f.und a signif.cant positive correlation b.tween peer victimization and online trolling, with hostile attrib.tion b.as serving as a mediator. In addition, trait mindf.lness moderated the direct relationship b.tween peer victimization and online trolling. Specif.cally, the ef.ect of.peer victimization on online trolling was attenuated when adolescents had high levels of.trait mindf.lness. The results of.the study emphasized the joint role of.peer and personal f.ctors in adolescents’ online trolling b.havior and provide certain strategies f.r intervening in adolescents’ online trolling b.havior. Conclusion: The results of.the study suggest that strategies f.cusing on peer support and mindf.lness training can have a positive impact on reducing online trolling b.havior, promoting adolescents’ mental health, and their long-term development. © 2024 The Authors.
