I see a pattern emerging here, as I also scored highly on schizophrenia and PTSD (as well as the expected depression, mental dullness, etc). My highest score was on emotional alienation, which I suppose makes sense, closely followed by "Lack of Ego Mastery, Conative".
As has been said, taking the test ourselves is so unreliable, but it is interesting. I'd be curious to know how my results would be interpreted by a 'professional'.
