摘要

Adolescent suicide, particularly among youth aged 10–14, is a critical global issue. While both bullying victimization and childhood trauma are known risk factors for suicidal behavior, the interactive and cumulative effects of these adversities on the trajectory of suicide risk remain largely unexplored. This study investigates suicide risk trajectories among adolescents experiencing high levels of bullying, childhood trauma, or both. It also examines psychache, depression, emotional regulation self-efficacy, and teacher-student relationships as influential factors. A total of 1,246 adolescents (51.77% female; Mage = 13.58, SD = 0.75) participated in a three-wave longitudinal study. Latent growth modeling assessed suicide risk trajectories, with risk and protective factors included as covariates. Adolescents experiencing both high victimization and trauma exhibited the highest initial suicide risk (intercept = 8.06, p < 0.001) and the most rapid decline over time (slope = −1.06, p < 0.001). However, their risk remained significantly higher than that of adolescents exposed exclusively to high bullying (intercept = 6.87, p < 0.001) or exclusively to high trauma (intercept = 7.01, p < 0.001). Psychache (β range: 0.10–0.12, p < 0.001) and depression (β range: 0.10–0.13, p < 0.01) emerged as significant risk covariates, whereas emotional regulation self-efficacy (β range: −0.10 to −0.03, p < 0.05) functioned as a protective covariate. Effective prevention should prioritize identifying high-risk adolescents. Interventions should prioritize addressing psychache and depressive symptoms among high-risk individuals while promoting emotional regulation self-efficacy and strengthening external support networks.
