Resumen: Cyberbulling is one of the biggest challenges the school faces. However, the lack of coherence between the data of the literature review makes it necessary to consider which elements are the ones that truly lead to the appearance of cyber-victimization. Through the meta-analysis methodology, it has been tried to clarify the role of sex (k = 41 samples, n = 176,658 adolescents) and age (k = 45 samples, n = 238,977 adolescents) in cyber-victimization. The effect size for the random model is small for both sex (r = 0.058; p < 0.00, 95% CI = 0.090; 3.45) and for age (r = 0.094; p = 0.004; 95% CI = 0.015; 2.910). Indications of significant differences in sex are observed, with women being the most affected. However, the results of the meta-regression have shown how the North American culture plays a key role in age as a moderating variable in relation to the rest of continental cultures. These results support the conclusion that age and sex represent variables that influence cyber-victimization. More specifically, there is a positive relationship between age and cybervictimization, so that the older the age, the higher the cybervictimization, but this is negatively mediated by the American culture. At the same time, some socio-contextual characteristics also seem to have effects on this aspect. Considering this, some important practical implications emerge related to the need to address the study, care and prevention of cyber-victimization as well as any form of violence that occurs inside and outside the classroom.
