Cyber-victimization is a significant risk factor for suicidal ideation among adolescents. However, little research has studied how cyber-victimization may impact suicidal ideation over time, and little is known about what protective factors can buffer against these associations. Guided by the integrated motivational-volitional model of suicidal behavior, this longitudinal study inspected the mediating role of hopelessness in the relation between cyber-victimization and suicidal ideation and the moderating roles of mindfulness and perceived social support in those mediating associations. A total of 1110 Chinese early adolescents (46.1% female; M at Wave 1 = 12.90 years) participated in a three-wave longitudinal study with 6-month intervals. The results showed that cyber-victimization positively predicted adolescents' suicidal ideation 1 year later, and this effect was fully mediated by hopelessness. Mindfulness buffered against the predictive effect of cyber-victimization on hopelessness, and perceived social support buffered against the predictive effect of hopelessness on suicidal ideation. The results further showed that the indirect effect of hopelessness was more salient when there were lower levels of mindfulness and perceived social support. This study reveals the moderated mediation processes explaining the impact of cyber-victimization on adolescents' suicidal ideation. Fostering youth's mindfulness and providing social support may attenuate the effects by which cyber-victimization causes suicidal ideation via hopelessness.
网络受害是青少年自杀意念的一个重要风险因素。然而，很少有研究探讨网络受害如何随时间影响自杀意念，对于哪些保护因素可以缓冲这些关联也知之甚少。在自杀行为的综合动机-意志模型的指导下，这项纵向研究考察了绝望感在网络受害与自杀意念关系中的中介作用，以及正念和感知社会支持在这些中介关联中的调节作用。共有1110名中国青少年早期学生（46.1%为女性；第1波时的平均年龄为12.90岁）参与了一项为期三年、间隔6个月的纵向研究。结果表明，网络受害正向预测青少年1年后的自杀意念，且这一效应完全由绝望感介导。正念缓冲了网络受害对绝望感的预测作用，感知社会支持缓冲了绝望感对自杀意念的预测作用。结果还表明，当正念和感知社会支持水平较低时，绝望感的间接效应更为显著。本研究揭示了解释网络受害对青少年自杀意念影响的调节中介过程。培养青少年的正念并提供社会支持，可能会减弱网络受害通过绝望感导致自杀意念的影响。
