This study explores the association between bullying victimization and suicidal ideation and determines the mediating role of psychological suzhi and the moderating role of perceived school climate. 855 (N boy = 417, N girl = 438; M age =13.18, SD = .78) students in this study from grade 7 to grade 9 completed questionnaires of the mentioned study variables. The results indicated that bullying victimization positively predicted adolescents' suicidal ideation. Psychological suzhi partially mediated the effect of bullying victimization on suicidal ideation. However, for adolescents with higher levels of perceived school climate, bullying victimization was correlated more strongly with suicidal ideation and weaker with psychological suzhi. Results meant that the more frequent and more severe the bullying, the higher the likelihood of suicidal ideation among adolescents. Psychological suzhi may act as a potential mechanism through which bullying victimization leads to suicidal ideation, nevertheless, perceived school climate not only buffered bullying victimization's effects on suicidal ideation, but also protected psychological suzhi from the negative influence of bullying.
Keywords adolescents • bullying victimization • suicidal ideation • psychological suzhi • perceived school climateSuicidal ideation refers to the idea and intention of an individual to voluntarily end his life, which is an essential psychological activity in the early stage of suicidal behavior (Zhang, 2005). In China, the largest developing country, about 250,000 people die of suicide every year, and about 2,000,000 attempt suicide, which has become the fifth leading cause of death in China and the first leading cause of death among young Chinese aged 15 to 34 (Beijing Suicide Research and Prevention Center, 2007). The prevalence of suicidal ideation differed statistically between genders and among grades (Klomek et al., 2009;Laukkanen et al., 2005;Shen & Wang, 2020). Notably, the suicide attempt rate among junior high school students was higher than that among senior high school (Shen & Wang, 2020). The differences in genders and grades are very essential in the study of adolescent suicidal ideation. Therefore, it is important to explore the mechanism of individual and environmental factors that influence the formation of suicidal ideation among junior high school students, which will provide a strong theoretical guidance for future clinical staffs workers to intervene in suicide behavior.
