Cyberbullying is intentional aggression online such as threats or humiliation. A study found 4-6% of youth experienced online harassment in 2013, and 15% had been aggressors. Those who were both aggressors and victims reported more psychosocial problems. While parental monitoring did not reduce cyberbullying rates, healthy parent-child relationships were important. The data is limited as severity and frequency of abuse are hard to measure, and more activity occurs online now. Teaching appropriate internet use in schools may help address the issue.
