I played with a free online cbt and got much further than their average participant in this study.. I'm not sure if there is any use to cbt for depression, but I would suspect that it would work better in a preventative fashion. I.e. I did notice that I can let thinking about some social interactions go where they would bother me in the past, but if I was depressed when I played with it, then maybe I would just notice how bad I was at benefiting from CBT at the moment where I should be letting something go.
