This has both positive and negative consequences. One of these consequences is a rise in cyberbullying cases, which could lead to negative effects for victims. Therefore, it is important to research ways to prevent cyberbullying. The goal of this research paper was to investigate the relationship between social media use and perpetration of cyberbullying and what role gender plays in this relationship, thereby possibly identifying gender and social media use as possible risk factors for perpetration of cyberbullying. The study assessed self-reported social media use including sexting and cyberbullying experiences and behaviours in a sample of 120 young adults between the ages of 18 to 24 years old (N = 38 males, Mean age = 21.94). Data was analysed with a multiple regression analysis. Results showed that, for women, there was a positive relationship between social media use and the perpetration of cyberbullying. For men no such relationship was found. Our findings are in line with evolutionary and gender socialization theories that suggest women are more inclined to use indirect forms of aggression whereas men are more inclined to use direct forms. These results have implications for future research into risk factors for cyberbullying and for identifying risk factors to prevent perpetration in practice. The focus in research and in practice should not only lie in identifying individual risk factors, but also consider the importance of gender effects.Show less
