This study examined the mediating role of social anxiety in the relation between cyberbullying victimization and nonsuicidal self-injury (NSSI), as well as the moderating role of emotion reactivity in those associations. Participants included 2,864 adolescents (Mage = 12.46, SD = 1.36, 47.1 percent girls). Results of path analysis showed that cyberbullying victimization was significantly related to NSSI, and social anxiety plays a mediating role in the relation between them. Emotion reactivity strengthened the effect of cyberbullying victimization on NSSI and of social anxiety on NSSI. The results further showed that the mediating effect of social anxiety was more prominent for youths who have higher levels of emotion reactivity. Interventions to reduce adolescent social anxiety and emotion reactivity may interrupt the pathway from cyberbullying victimization to NSSI.

青少年早期网络欺凌受害和非自杀性自伤：社交焦虑和情绪反应的调节调解模型。

本研究检验了社交焦虑在网络欺凌受害与非自杀性自伤 (NSSI) 之间关系中的中介作用，以及情绪反应在这些关联中的调节作用。参与者包括 2,864 名青少年（Mage = 12.46，SD = 1.36，47.1% 是女孩）。通径分析结果表明，网络欺凌受害与NSSI显着相关，社交焦虑在二者关系中起中介作用。情绪反应加强了网络欺凌受害对 NSSI 和社交焦虑对 NSSI 的影响。结果进一步表明，社交焦虑的中介作用在情绪反应水平较高的青少年中更为突出。
