We are trying to a build a dataset. Basically, if enough people answer enough questions, we can tell them interesting things about their mental health - maybe even something that might help.
There's a long-winded attempt to explain this idea more thoroughly here, and an example of a (mildly) interesting result from the first 124 people here.
But if you have a few minutes, I suggest just taking the baseline 15-item survey to get a sense of it, and then you can see some results explore from there.
