title: Prevalence and correlates of the perpetration of cyberbullying among in-school adolescents in Oyo State, Nigeria.
abstract: OBJECTIVE
  Cyberharassment/cyberbullying is a global problem that has been inadequately investigated in developing countries. In this paper, we present findings on the prevalence and predictors of perpetration of cyberbullying among in-school adolescents in Oyo state, Nigeria.
  
  
  METHODS
  A total of 653 students were selected via multi-stage sampling. Information on history of perpetrating harassment via an electronic medium in the 3-month period preceding the survey was obtained.
  
  
  RESULTS
  Respondents' mean age was 14.2±2.2 years and 51.3% were females. All respondents had personal mobile phones and about half had Internet access. About 40% accessed the Internet every day while about 48% accessed it at least once to several times a week and <5% accessed it about once every 2 weeks. One hundred and fifty-six (23.9%) had harassed someone electronically, 260 (39.8%) had been victimized, and 137 (21.0%) were both victims and perpetrators. Common modes of harassment were via phone calls 99 (63.5%), chat rooms 70 (44.9%), and text messages 60 (38.5%). Students who had been victims of cyberbullying (OR=21.76, 95% CI=12.64-37.47) and those with daily Internet access (OR=2.32, 95% CI=1.28-4.19) had significantly higher Oods of being perpetrators.
  
  
  CONCLUSIONS
  About a quarter of students were perpetrators of cyberbullying, and the correlates of perpetration were history of cyber victimization and daily Internet access. Intervention programs must be instituted for victims as well as frequent users of the Internet to curb the problem in the study area.
