Bullying is defined as the repeated act of violence toward victims on the basis of power imbalance. A new type of bullying is derived with the development of digital communication technologies such as the internet and mobile phones which is called "cyber bullying". Today being a victim of cyber bullying has become a major public health problem among adolescents and young people. While the act of cyber bullying is more common among boys, girls are reported to be usually the victim. Being a part of an ethnic minority, gender other than heterosexuality is a risk factor for cyber bullying victimization. There is a relation between eating behavior disorders, anxiety, depression, suicidal tendencies, anger, aggression, non-alcohol-addiction with mental health problems and cyber bullying victimization. Quality of life seems to be low in both victims and bullies. Also, disturbances among parents, siblings' relationships, and academic underperformance are associated with cyber bullying. It can be said that all subjects related to social and mental health can be affected by cyber bullying. The purpose of this review is to reveal what cyber bullying is, its risk factors, and its relationship on adolescents and young adults physical and mental health.
IntroductionBullying is defined as an act of violence repeated over time in which there is a power imbalance between the victims and those who bully [1,2]. In traditional bullying, the victim and the bully are face-to-face. Traditional bullying can be categorized as physical like hitting-kicking, verbal like ridicule and threat, and relational like exclusion and spreading rumor. A new kind of bullying came into existence with the development of digital communication technologies such as the internet and mobile phone and is called "Cyber bullying" [3]. Cyber bullying is defined as deliberately and repeatedly damaging someone using digital technologies [4]. Cyber bullying is most commonly performed in the form of annoying messages and social attacks by unidentified messages through e-mail, instant messaging, chat rooms, and websites. The target audience in bullying / cyber bullying studies is categorized as the bullies, the victims, those who are both the bully and the victim, and those who are neither the bully nor the victim [1,2]. Modecki and colleagues report in the meta-analysis study of the results of eighty studies that traditional bullying is seen twice as much as cyber bullying, and that traditional and cyber bullying are highly correlated [3]. For this reason, it is seen that most of the studies related to the subject are handled together with traditional and cyber bullying. The purpose of this review is to reveal what cyber bullying is, its risk groups, and its effects on the physical and mental health of adolescents and young adults.
