Communication is one of the indispensable elements of human history. With the advancement in technology, the use of the internet, social media, and digital tools such as computers and cell phones has taken an important place in human life. Children and young people use the internet for different activities such as doing educational work, exchanging messages via e-mail, playing online games, shopping, using social networks, watching movies and listening to music. It is reported that the age group with the highest rates of computer and internet use is adolescents and young adults (16-24 and 25-34 age groups). Excessive and problematic use of information technologies and the transfer of relationships to virtual environments can bring about some negative situations that may occur in adolescents such as internet addiction and cyberbullying. Cyberbullying, which is the deliberate and regular use of digital technology such as computers, mobile phones and the internet to harass others, includes concepts such as cyberbullying, cyberbullying and cyber victimization. Bullying, which is a proactive behavioral problem, is a situation in which an individual or group repeatedly exhibits humiliating and aggressive behaviors to an individual or group that is relatively weaker than themselves. Bullying and cyberbullying faced by adolescents have become an important problem worldwide.The aim of this study is to determine the effect of a school-based bullying prevention program on adolescents' bullying victimization, tendencies and future expectations.
