Whether your child is bullied in the classroom or on his cellphone, the impact is the same.

“Cyberbullying”—any bullying that takes place online or via a mobile device—is just as dangerous to victims as in-person bullying, according to a newly released report. Kids who were victimized by cyberbullying were just as likely to skip school or consider suicide as kids who were bullied in more traditional ways. Girls and younger students in particular were more likely to think about killing themselves as a result of bullying.

The message to parents and educators is clear: Bullying is a real threat to our kids both on and off school property.

Cyberbullying can take place via text message or email, as well as on social networking sites. It can include hostile and harassing words as well as rumors, embarrassing pictures or videos, and even fake social media profiles and activities.

So what can parents do to discover and prevent cyberbullying? Careful and consistent supervision of your kids’ activities online, as well as monitoring their cellphones, is the key.
