Posting selfies could do more harm than good

In 2015, a statistic about social media use captured the Internet's attention. "More people have died of selfies than shark attacks this year." To be fair, very few people die of either selfies or shark attacks. But a wave of research continues to suggest that social media use can be a significant impediment to mental health. A new study points specifically to selfies as a mood and confidence-lowering activity.

Social media use has been linked to depression, anxiety, body dissatisfaction, and increased focus on appearance. These effects are fairly broad, but they seem to hit young women (who are the heaviest users of social media) especially hard. Yet many of the studies showing an association between heavier social media use and decreased mental health are correlational. As any of my students can quickly tell you: Correlation does not equal causation. In other words, just because social media use is correlated with negative outcomes doesn't mean that it caused those outcomes. It's possible that things like depression, anxiety, and poor body image actually drive greater social media use instead of the other way around. If you feel depressed, you might try to connect with people online to alleviate feelings of sadness. If you're struggling with poor body image, you might try to post attractive pictures of yourself in order to hear positive feedback from others about how you look.

If we truly want to understand the causal effects of social media use, we need to look at the results of carefully conducted experiments in which participants are randomly assigned to condition. A recent study published in the journal Body Image used this type of experimental design to take on one of the most vilified forms of social media activity - posting selfies.

First, some background. Selfies are often used as a form of what's called impression management. Any time you're trying to influence others to see you the way you want to be seen, that's impression management. Everyone engages in impression management. Posts are just one of the many ways people do this.

Interviews with young women reveal that impression management is one of the major reasons they use social media. To be certain, young women are not the only group that uses social media this way, but young women do post more pictures of themselves than other demographic groups. A recent survey of women between ages 16 and 25 in the UK found that many spent hours a week taking, editing, and posting selfies.

So, back to the research at hand. A group of 113 Canadian women between the ages of 16 and 29 participated in the study led by researchers at York University. When the women arrived, researchers gave them an iPad and took them to a private space. Each woman was randomly assigned a different condition.

Results showed that it didn't matter whether the women were allowed to retouch their image. The selfie-posting groups showed increases in anxiety and decreases in confidence. They also felt less attractive after posting a selfie. Though some variables (like depression) did not seem to be affected by posting a selfie, none of the variables measured showed any evidence of a positive psychological effect of selfie posting.

What should we make of these findings? First, it's essential that young women (or anyone!) not be shamed for their social media behaviour. In addition, some women may find the process of posing for, editing, and posting selfies fun or empowering. But it's worth considering the fact that many of the activities we engage in that might seem fun in the moment can also have a negative impact on our mental health and well-being.
