Stopbullying.gov is a website with a myriad of resources that is maintained by the U.S. Department of Health and Human Services. It defines bullying as “[b]ullying is unwanted, aggressive behavior among school aged children that involves a real or perceived power imbalance. The behavior is repeated, or has the potential to be repeated, over time. Bullying includes actions such as making threats, spreading rumors, attacking someone physically or verbally, and excluding someone from a group on purpose.” Cyberbullying is defined as “bullying that takes place using electronic technology. Electronic technology includes devices and equipment such as cell phones, computers, and tablets as well as communication tools including social media sites, text messages, chat, and websites. Examples of cyberbullying include mean text messages or emails, rumors sent by email or posted on social networking sites, and embarrassing pictures, videos, websites, or fake profiles.”
The Center for Disease Control and Prevention published Youth Violence: Technology and Youth — Protecting Your Child from Electronic Aggression, which is a tipsheet with strategies to deal with email, texting, chat rooms, websites, and instant messaging.
A February 2013 article by William E. Copeland, Dieter Wolke, Adrian Angold, and E. Jane Costello, Adult Psychiatric Outcomes of Bullying and Being Bullied by Peers in Childhood and Adolescence was published in JAMA Psychiatry, which found a link between youth who were victims of bullying and a higher risk of certain mental health disorders as youth and on into adulthood. A summary is available here.
