Sorry, I think you are mistaking what I'm writing. I'm referring to this article and basing it of PEW Research on adolescence with depression. The addition of more sleep hasn't changed anything in this survey. In regards to already existing reports by PEW on the rates of depression which in teenagers and in more specifically girls have an exponential growth in depression rates. Its not due to a change in social stigma but rather the use of social media. Specifically facebook and instagram which most teenage girls spend the majority of their time on.
