Principles of Prevention


Each year, more than 57,000 people lose their lives to violence.  Another 2.2 million are treated in emergency departments across the United States for violence-related injuries.  Violence also erodes communities by reducing productivity, decreasing property values, and disrupting social services.

One way CDC is helping the nation prevent violence is through a free on-line course that's available 24 hours a day, seven days a week. It's called Principles of Prevention. The course—which offers continuing education credits—teaches key concepts of primary prevention, the public health approach, and the social-ecological model. Participants complete interactive exercises to learn to help prevent the following five types of violence:

  • Child abuse and neglect
  • Intimate partner violence
  • Sexual violence
  • Suicide
  • Youth violence

Principles of Prevention is designed for those working to stop violence from ever happening. It helps professionals move from the problem to the solution. This course teaches the fundamentals of effective violence prevention methods and incorporates the growing body of research on what works.
