To explore the mediating role of depression symptoms in the relationship between bullying and suicide risk, and to analyze the moderating effect of emotional intelligence.
A stratified cluster sampling method was employed to select 16 388 students from 20 primary and secondary schools in the Pidu District of Chengdu, who completed self-administered questionnaires. Structural equation modeling was established to test the mediating and moderated mediating effects.
Among the participants, 28.5% were involved in bullying, and 29.2% exhibited a high risk of suicide. The direct effect between bullying and suicide risk was 0.154 (95%CI: 0.136-0.173, P < 0.001), while the mediating effect of depression symptoms was 0.164 (95%CI: 0.153-0.175, P < 0.001). Emotional intelligence negatively moderated the mediating pathway: at low levels of emotional intelligence, the mediating effect (bullying → depression symptoms → suicide risk) was 0.157 (95%CI: 0.144-0.169),whereas at high levels of emotional intelligence, the mediating effect was 0.114 (95%CI: 0.103-0.126).
There is a positive association between bullying and suicide risk among children and adolescents, with bullying indirectly influencing suicide risk through depression symptoms. Additionally, emotional intelligence negatively moderates the mediating effect of depression symptoms. Interventions aimed at alleviating depression symptoms and enhancing emotional intelligence may be effective strategies to mitigate the adverse effects of bullying on the psychological and behavioral health of children and adolescents.
