An influential doctors' group says "Facebook depression" is among potential harms to teens who use social networking sites.
Researchers disagree on whether it's a distinct condition or simply an extension of depression kids feel offline, too.
But there are unique aspects that can make Facebook especially tough for troubled kids. That's according to Dr. Gwenn O'Keeffe. She's lead author of the American Academy of Pediatrics' new social media guidelines.
O'Keeffe says Facebook provides a skewed view of what's really going on. And some teens say that chalking up online friends and photos amount to a popularity contest.
The guidelines were being published online Monday in Pediatrics.
