Experts say the results of a new study should shock parents into talking with their teenagers about dating.
An online survey of more than 1,000 teenagers found that nearly a third of all those surveyed say they have fallen victim to dating violence.
In the survey, violence was defined as physical, sexual or emotional.
Although girls are more likely to fall victim to violence, researchers found that they were almost as likely as boys to say they would commit dating violence.
Rates jumped as teens got older and were linked to ethnicity and income levels.
