Summary: The Internet represents both risks and opportunities for young people. To protect youth who are at risk for online addiction, bullying, and solicitation, we need more research to understand which youth may be most susceptible and to develop targeted interventions to protect them. The Internet also has many positive aspects and can be used to enhance youth learning and empowerment; although it is a tremendous health resource and can be used to cheaply deliver interventions, we need to understand how to better implement them to enhance their effectiveness.
