RILEY Connors sees plenty of selfies on Facebook.
The Rockhampton teenager is known to take a few herself.
But Riley wasn't surprised to hear of new research that links selfies to certain mental health conditions related to a person's obsession with their looks.
"(People who post selfies) really want people to see that they look good more than anything," she said.
Riley agreed that selfies are often taken for attention and to try to get approval.
And she admits it can create an unhealthy environment for young people who are more likely to post a selfie when they see others doing it.
"Everyone wants to see you doing good, but not better than them," she said.
The study by the Pew Research Center linked selfies with a social dependence that can cause very low self-esteem.
Yet other experts have likened selfies to self-portraits, used to explore identity and sense of self.
