The study uses historical data, change in mental health before and after Facebook was introduced to a campus. Which is a very cool way to make use of a natural control. Nice study.

Seems clear facebook had negative impact on mental health on campus.

Facebook then was also likely very different from Facebook now. So not exactly sure what recommendations for today can be drawn from it.

It's interesting to note that the data shows facebook was damaging mental health at the same time that many readers of this comment were most enthusiastic about Facebook.
