Abstract
With regard to negative consequences, cyberbullying is recognized as one of the most traumatic types of cyber aggression. The aim is to study the specific features of adolescents and youth's cyberbullying experience in the role of an aggressor, victim or bystander, as well as awareness on the part of parents of adolescents. A total of 3395 adolescents, youth and parents filled out specially designed questionnaires. Older adolescents turned out to be at higher risk of cyberbullying. In two-thirds of cases, cyberbullying is related to real-life incidents. Aggressors are motivated by domination and entertainment, primarily employing strategies of social exclusion, harassment and denigration. As victims of cyberbullying, younger adolescents turn to their parents and friends for social support, whereas older adolescents and young adults are more likely turn to their peers. In the role of a bystander, almost half of younger adolescents and about a third of older adolescents and young adults choose the prosocial strategy of protecting a victim. The parents often underestimate the experience of encountering cyberbullying or find it difficult to assess such experience. The identified risk groups and strategies and the lack of parents' awareness are important to take into account when drawing up cyberbullying prevention programs.
