Yeah, in fact the basic result is that there's about a .05-.20 ish correlation between social media and various mental health problems, broadly defined (not depression though, it's a zero). And this correlation doesn't change. Correlation is not causation and this study makes no attempt to solve that problem. Note also that if the association is causal, and the size of the association remains the same, but the level of the independent variable goes up - i.e. people spend more time on their phones/TVs/computers - then the size of the resulting problem will go up too.
