A new study on teen bullying surveyed 5,600 children between the ages of 12 and 17 years old to address various forms of bullying and cyberbullying, "sexting" and dating violence. Thoughts of suicide, deviant behavior, resilience, and ability to cope were also examined. A few findings: Girls are more likely to be bullied online. Eighty-three percent of those bullied online are also likely to be bullied at school. Insight: Bullying at school is often not reported to parents. However, if you discover your child is bullied online, the chance that they are being bullied at school is very high.
