There is substantial evidence linking bullying victimization to suicidal ideation, but the mechanism behind this link is not well understood. This study investigates whether depressive symptoms mediate the relationship between bullying victimization and suicidal ideation, and whether perceived family economic strain moderates this mediation.
Data were collected from 7,702 adolescents (mean age = 14.74 ± 1.69 years, 52% girls) using a self-report questionnaire that assessed bullying victimization, depressive symptoms, suicidal ideation and perceived family economic strain. Mediation and moderated mediation analyses were conducted using the PROCESS macro in SPSS.
Suicidal ideation was significantly associated with both bullying victimization and depressive symptoms, as determined by linear regression analysis (both p < 0.001). The relationship between bullying victimization and suicidal ideation was partially mediated by depressive symptoms, accounting for 66.74% of the effect. Additionally, perceived family economic strain could moderate the link between bullying victimization and depressive symptoms (β=-0.017, p < 0.001), indicating that increased perceived family economic strain attenuates the impact of bullying victimization on depressive symptoms.
Our research affirms bullying victimization substantial influence on adolescent suicidal ideation, with depressive symptoms mediating this link. The study also reveals that perceived family economic strain moderates this relationship, indicating the necessity for interventions that address both psychological and economic factors to holistically support the mental health of bullied adolescents.
有大量证据表明受欺凌与自杀意念之间存在关联，但这种关联背后的机制尚不清楚。本研究调查抑郁症状是否介导受欺凌与自杀意念之间的关系，以及感知到的家庭经济压力是否调节这种中介作用。
使用一份自我报告问卷收集了7702名青少年（平均年龄=14.74±1.69岁，52%为女孩）的数据，该问卷评估了受欺凌情况、抑郁症状、自杀意念和感知到的家庭经济压力。使用SPSS中的PROCESS宏进行中介和调节中介分析。
线性回归分析确定，自杀意念与受欺凌和抑郁症状均显著相关（p均<0.001）。受欺凌与自杀意念之间的关系部分由抑郁症状介导，占效应的66.74%。此外，感知到的家庭经济压力可调节受欺凌与抑郁症状之间的联系（β=-0.017，p<0.001），表明感知到的家庭经济压力增加会减弱受欺凌对抑郁症状的影响。
我们的研究证实了受欺凌对青少年自杀意念有重大影响，抑郁症状介导了这种联系。该研究还表明，感知到的家庭经济压力调节了这种关系，这表明有必要采取干预措施，同时解决心理和经济因素，以全面支持受欺凌青少年的心理健康。
