The rapid development of digital technology and increasing use of social networks among the young generation have produced the phenomena of growing electronic media violence among peers (electronic peer violence). The aim of the paper is to analyze the peer violence in face-to-face communication and through the use of electronic media and point to the most commonly means used by the perpetrators to hurt the victim. School staff, parents and pupils play an important role in presented preventive programs. Since the electronic media violence is becoming a growing problem the aim of the paper is to assess the correlation between the frequency of social networks use and experienced or perpetrated forms of peer violence on social networks among the elementary school pupils (sixth and seventh grade). Two instruments have been constructed for the purpose of this paper: Questionnaire of socio-demographic characteristics and Scale of the frequency of peer violence on social networks. Research results show that 95% of pupils have profiles on social networks. 19,75% of the interviewed pupils have experienced some kind of violence on social networks during their schooling time; 7,5% pupils have experienced it several times; 2,25% pupils have been bullied once or more times a week. 14,6% pupils have committed some kind of violence on social networks once or twice during their schooling time; 7,8% pupils were violent on social networks against their peers several times; 1,8% pupils have bullied peers on social networks once or more times a week. The results confirm the correlation between the experienced and perpetrated violence on social networks among peers (r=0,596; p<0.01), observers and victims (r=0,563; p<0.01) and among observes and perpetrators (r=0,456; p<0.01) which is in accordance with the findings of other researches. It is possible to conclude that perpetrators are often victims and observers of peer violence and vice versa.
