"These meetings may have been benign, but for an adolescent girl to do it is dangerous," says Jennie Noll, PhD, a psychologist at Cincinnati Children's Hospital Medical Center and the study's lead author.

Moreover, abused or neglected teenage girls were more likely to present themselves online in a sexually provocative way than other teenage girls. Research shows that high-risk, online profiles are more likely to lead to offline meetings, according to Dr. Noll, director of research in behavioral medicine and clinical psychology at Cincinnati Children's.
