Query: Useful, but limited

I have to say that I felt let down by this book. It was recommended to me, and I picked it up with anticipation, ready to buy a copy. I was very disappointed, (as a psychotherapist specializing in recovery issues), to find that the dual diagnosis approach to recovery and mental health was mentioned exactly once, then ignored in favor of the old "either/or" paradigm discarded by most of us in the eighties; thus the sections on addiction and mental health are of limited use, since the interactions between the two are ignored. This book is better than nothing, but you'll have to infer your treatment plans if you let yourself be limited by its contents. Hopefully a forthcoming edition will bring it's recovery paradigm into the nineties, before they're too far behind us.
