Teen dating violence is a pattern of abusive behavior exhibited by one or both teenagers in a dating relationship. The behavior includes, but is not limited to, physical abuse, emotional abuse, and sexual abuse. Polls in the United States and scientific studies from around the world (see "statistics" section below) show that substantial portions of teenagers have perpetrated and/or experienced dating violence. However, most parents do not recognize teen dating violence as a significant problem.
