Cyberbullying has to become one of the main concern in the educational field of children and adults. Adults have to be aware of this new phenomenon and its’ negative effects in order to prevent and help children deal with it. Researchers found that cyberbullying has serious psychological effects on children and those effects influence the adult life of those who were confrunted with it. This study examines the roles of gender, age and internet frequency in cyberbullying for Romanian adolescents. The study also intends to investigate the differences on depression, anxiety, and self-esteem depending on the gender, age and cyberbullying status of adolescents. The participants were 495 Romanian adolescents, aged between 13 and 18, recruited from secondary and high schools. They filled in four standardized self-report scales. Our findings show that adolescents who spend more time on the internet (more than 15 hours per week) have higher scores on cyberbully and cybervictimization, with boys having higher scores on cyberbullying than girls. Also, girls are more depressed, more anxious and have lower self-esteem than boys. Cybervictims and adolescents with double role are more depressed and more anxious than those with no experience in cyberbullying. Furthermore, adolescents with double role are more anxious and have lower self-esteem than cyberbullies. This study supports the results of previous studies which underlined the psychological negative impact of cyberbullying on today adolescents, the future adults of the society.
