Relationships Among Cyberbullying, School Bullying, and Mental Health in Taiwanese Adolescents

BACKGROUND This study examined the relationships among cyberbullying, school bullying, and mental health in adolescents. METHODS In 2010, a total of 2992 10th grade students recruited from 26 high schools in Taipei, Taiwan completed questionnaires. RESULTS More than one third of students had either engaged in cyberbullying or had been the target (cybervictim) of it in the last year. About 18.4% had been cyberbullied (cybervictim); 5.8% had cyberbullied others (cyberbully); 11.2% had both cyberbullied others and been cyberbullied (cyberbully-victim). About 8.2% had been bullied in school (victim); 10.6% had bullied others (bully); and, 5.1% had both bullied others and had been bullied in school (bully-victim). Students with Internet risk behaviors were more likely to be involved in cyberbullying and/or cybervictimization; students who had cyberbullying or victimization experiences also tended to be involved in school bullying/victimization. After controlling for sex, academic performance, and household poverty, cyber/school victims and bully-victims were more likely to have lower self-esteem, and cyber/school victims, bullies and bully-victims were at a greater risk for serious depression. CONCLUSIONS Both cyberbullying and school bullying and/or victimization experiences were independently associated with increased depression.
