A new Cincinnati Children's Hospital survey finds one-third of teen girls actually have an in-person meeting with somebody they met online.

Psychologist Jennie Noll says abused or neglected teenage girls are more likely to present themselves in a more sexually provocative way online and therefore have more offline meetings. Noll studied the Internet and social media habits of 250 girls. About half were abused. She followed up a year later. Noll says the meeting part is scary for this age even though plenty of adults do it.
