Cyberbullying has become a massive occurrence among young people on the Internet, especially on social networks. Considering that the current studies on cyberbullying are mainly concerned about the socio-psychological characteristics of victims and violators and the parameters of using internet and social networks, the aim of this paper was to link cyberbullying with the high school students’ social capital. A quantitative survey was conducted and it included 157 respondents. What was investigated is the connection between cyberbullying and the frequency of internet usage, as well as the connection between becoming a cyber victim and a cyberbully with specific dimensions of social capital, that is with bridging, bonding social capital and general trust. The obtained results show that there is no statistically significant difference between exposure to cyberbullying and the frequency of internet usage. Furthermore, it has been found that respondents who have greater trust towards social groups with whom they have frequent relations are less likely to become victims of cyberbullying, while the link between exposure to cyberbullying and the trust towards social groups with whom respondents have fewer contacts is not statistically significant. The results also show that respondents with a larger bonding social capital are less exposed to cyberbullying, while the link between exposure to electronic violence and bridging social capital is not statistically significant. Lastly, it has been noted that the students with the larger bonding social capital are not so much involved in cyberbullying. On the other hand, with regard to bridging social capital there is no statistically significant difference in cyberbullying.
