How common is teen sexting? Last week we reported on a new study of more than fifteen hundred Internet users age ten to seventeen. It found that only two and a half percent of them had sexted in the past year. It also found that only one percent of the images might violate child pornography laws.

That study came from the University of New Hampshire. But another new report suggests much higher rates. Both studies defined "sexting" only to mean sending or receiving naked pictures.

Psychologist Jeff Temple is an assistant professor at the University of Texas Medical Branch in Galveston.

JEFF TEMPLE: "We found actually about twenty eight percent of teens had sexted."

Mr. Temple says reports from medical offices and school officials support that finding.
