The lead author of the study, psychologist Dr. Jennie Noll, says 30 percent of teen girls report meeting with people they met on the Internet.
And the research shows those meetings are more likely to happen for girls who engage in high-risk behaviors.
Noll says those who troll the web for vulnerable teens are looking for a specific type of online profile.
Noll says another point of concern is that abused or neglected teenage girls are more likely to present themselves online in a sexually provocative way.
Noll says parents can do a lot to change their child's behavior and just need to be willing to have those hard conversations about the dangers online.
She adds that establishing good face-to-face family communication time that doesn't involved being plugged in, can go a long way in building trust.
