Undoubtedly, information and communication technologies have rapidly developed, becoming an essential part of adolescents' lives. This progress has been further accelerated by the restrictive measures to mitigate COVID-19 transmission. However, beyond the benefits offered by the digital world, there is a wide range of phenomena that impact the development and mental health of individuals. Consequently, this study aimed to assess the levels of cyberbullying among adolescents from a public institution in Santander, Colombia, during the COVID-19 pandemic. The sample consisted of 77 adolescents. The research employed a quantitative approach, with a descriptive scope, a non-experimental design, and a convenience non-probabilistic sampling method. It was identified that the majority of the participants had a higher incidence in the role of cyber observers. Statistically significant differences were found between the study variables and the levels of cyberbullying. These findings both align with and diverge from what is established in the scientific literature. Therefore, it is suggested that further studies delve into the intricacies of the phenomenon and implement monitoring programs to reduce online violence.
