Definitely worth RTA before comment - at least skip to page 25 for the visual charts. It looks like social media usage may not correlate to depressive symptoms.
Author's conclusion:
> This paper finds that social media usage decreases the level of depressive symptoms employing a two-way fixed effects model. Direct information on people’s feelings about using social media also supports that using social media can be beneficial. This result implicates that society may have underestimated the importance and contribution of social media.
There's a lot which can be discussed in terms of what is being measured in this study, and what else might make sense to measure. Or how this study's results compare against other similar studies.
