          Objective To explore the mediating effect of depressive symptom on the relationship between peer bullying patterns and suicidal ideation, and to provide suggestions for school bullying and suicide prevention for adolescents.

          Methods A follow-up cohort was established in a junior middle school in Suixi County, Anhui Province in September 2019 (T1). The first follow-up was conducted in September 2020 (T2). A total of 1 687 junior high school students participated in this study. Self-designed peer bullying questionnaire, center for Epidemiological Studies Depression Scale for children, and questions regarding suicide-related behaviors were administered.

          Results Prevalence of suicidal ideation, victimization and bullying were 28.3%, 27.0% and 24.4%, respectively. The latent class analysis (LCA) identified three heterogeneous peer bullying classes: low aggressive-victims (71.4%), high aggressive-victims (3.3%), high verbal and relational aggressive-victims (25.3%). The low aggressive-victims class was used as the reference group, T1 depressive symptom mediated the association between high aggressive-victims (mediating effect = 0.43, P<0.05), high verbal and relational aggressive-victims class (mediating effect = 0.29, P<0.05) and T2 suicidal ideation.

          Conclusion Depressive symptom plays a mediating role in the relationship between peer bullying and suicidal ideation. In order to prevent peer bullying and suicide-related psychological behaviors of adolescents, educators should pay attention to adolescents’ mental health when formulating corresponding measures.
