The aim of this study was to examine relations and differences in age, gender, empathy and self-esteem considering perpetration and experiencing of cyberbullying. The sample consisted of 218 students (111 girls and 107 boys) in sixth and eighth grades of elementary school and second and fourth year of high school. The results revealed significant positive correlation between age and committing cyberbullying. This means that boys are more involved in committing cyberullying. No significant correlation was found between gender and experiencing cyberbullying. Furthermore, the results show that students with lower level of empathy were more often perpetrators of cyberbullying, whereas students with low selfesteem reported higher exposure to that type of bullying. Obtained differences in age and gender considering cyberbullying indicate that male participants as well as high school students are more involved in committing cyberbullying compared to female participants and elementary school students. No difference in experiencing cyberbullying with regard to age and gender has been found. Also, no difference in empathy between different groups of partakers (bullies, victims, bullies/victims, uninvolved) was established, wherein bullies/victims showed lower self-esteem than uninvolved group. Two regression analysis were conducted. Frequency of comitting cyberbullying and selfesteem were found to be significant predictors of experiencing cyberbullying. On the other hand, frequency of experiencing cyberbullying were found to be significant predictors of committing cyberbullying. Frequency of perpetrating of cyberbullying is the most significant predictor of experiencing cyberbullying and vice versa. These data are important in order to draw the attention and to contribute for better understanding of cyberbullying and forming and prevention programs.
