Abstract: In recent years, frequent campus safety incidents put adolescents' behavior problems in sharp focus. Bullying and non-suicidal self-injury (NSSI) have been investigated. Bullying, as a negative behavior, belongs to a sub-type of aggressive behaviors, including bullying perpetration to others, bullying victimization, and bully-victim. NSSI occurs frequently in adolescents, which is an independent risk factor for suicide. At present, most scholars believe that bullying victimization is positively correlated with NSSI, and there may be mediating or moderating effects between them. However, the relationship between bullying perpetration to others and NSSI is still uncertain due to the lack of researches. This paper summarizes the relationship between bullying and NSSI to provide clues or new thoughts for preventing and controlling non-suicidal self-injury in adolescents.
