In terms of badness: my guess is they are also bad, although I don’t know what research has been done with happiness measures. Speaking to some psychiatrists, I gather it’s possible that some cases of schizophrenia don’t have to be bad (e.g. you hear voices but it doesn’t bother you) but often they are.
In terms of treatment: different. I gather schizophrenia requires at least different types of CBT from those used to treat depression, and typically anti-psychotics, so it might be quite a lot less susceptible to the approach I suggest, but I’m not really sure.
