There were a few that were not accurate though for me because for example I experience (at times) a great level of dissociation but not the same type as those questions. well actually I do I guess... Hmm maybe the dissociation one is accurate. I don't know but for example the one about the eating disorders - it was all about over eating where as I constantly starve myself and won't eat for days until I'm near passing out. Or the one about anxiety. I have anxiety about 99% of my life but the questions were worded in a way That prevented me from answering the way I wanted.
But overall I think it's a great screening tool to get a basis on what to work on.
