title: Cyberbullying Among Greek High School Adolescents.
abstract: OBJECTIVE
  To investigate the presence of cyberbullying among Greek students and the efficacy of proposed preventive interventions.
  
  
  METHODS
  Three types of high schools (private, experimental and public) with different politics on on-line aggression were enrolled. All students of the aforementioned schools were asked to complete an anonymous questionnaire.
  
  
  RESULTS
  Around 62 % of the high school students experienced cyberbullying by electronic means, especially by cell phone, mostly the public school students (p 0.008). The bully was a stranger in more than 40 % of the cases. Over 60 % of the victims had not seeked help but dealt with the attack on their own. Only 20 % of the victims manifested sleep or eating disorders, physical/ psychological symptoms or changes in their social life as a consequence of the cyber-attack.
  
  
  CONCLUSIONS
  Cyberbullying is a usual phenomenon among high school students. The bully is frequently unacquainted to the victim. Most of the victims are not physically or psychologically affected by the cyber-attack and do not share the event with anyone. There was a slight difference in the response of the students to cyberbullying among the different school politics of on-line aggression.
