Bullying and suicide in high school students: Findings from the 2015 California youth risk behavior survey

ABSTRACT

School bullying and cyberbullying have been linked to suicidal behaviors through depression and alcohol, tobacco, marijuana, and other drug use. However, how these associations may differ across racial/ethnic groups remains relatively unknown. Using data from the 2015 California Youth Risk Behavior Survey, this study aims to examine two questions in different racial/ethnic subgroups: (1) Does bullying affect suicide? and (2) Does bullying have an indirect effect on suicide through depression and use of alcohol, tobacco, marijuana and other drugs? The sample consisted of 1,765 Californian youth attending grades 9–12. Logistic regression analyses indicate that being bullied is associated with increased odds of suicide across all racial/ethnic groups; depression mediates the effect of bullying on suicide for all racial/ethnic groups; alcohol use mediates the effect only for Hispanic youth; other drug use mediates the effect only for White youth; marijuana and tobacco use have no mediating role. These findings suggest that bullying may lead to suicide through different risk behaviors for youths of different racial/ethnic groups. Professionals who work with bullied youths need to treat depression more effectively to prevent suicide in service planning and provision. They also need to be aware of the racial/ethnic differences in the risk behaviors intercorrelated with bullying and suicide and provide appropriate treatment to the youth of specific race/ethnicity.
