> They found a statistically significant worsening in mental health symptoms, especially depression and anxiety, after the arrival of Facebook:

7% increase in number of students who reported having suffering, at least once during the preceding year, depression so severe that it was difficult for them to function

20% increase in number of students who reported anxiety disorders

2% increase in number of students expected to experience moderate to severe depression

3% increase in number of students experienced impairment to their academic performance due to depression or anxiety

I am suspicious of the methodology because of how quickly Facebook rolled out across most colleges/Universities. I want to say within a year. It feels unlikely that the data would be granular enough (and the survey given frequently enough at each University) to reach these sorts of conclusions.

You are right, and Facebook's roll-out is discussed in Section 2.2 of the paper.[1] The data sources are discussed in Section 3.1. They use the National College Health Assessment which surveyed students each semester.
