The Information and Communication Technologies have developed at a fast pace, integrating themselves in the daily life of adolescents and young people. For this reason, this non-experimental cross-sectional study analyzed the gender differences in problematic Internet use, cyberbullying and cyber-violence, as well as the possible relationship between these variables. The sample consisted of 456 students, from two Mexican universities, aged between 17 and 30 years (M = 19,86; DT = 2,12). The results showed few significant differences between men and women; likewise, significant positive correlations were found between most of indicators of problematic Internet use with cyberbullying; between problematic Internet use and cyber dating violence; and between cyberbullying and cyber dating violence. It was concluded that violent behavior of young people through new technologies seems to be generalized to relationships with peers and couples. It was discussed the results highlighting the need for more studies on these phenomena increasingly present in young people.
