this book was required reading for a course. Though this edition is a revised one, dated in the early 90's (the original was 1982), much of the information regarding psychiatric disorders and alcohol/substance abuse, in particular, are horrendously out of date!! As a licensed mental health counselor and a credentialed substance abuse counselor, I was somewhat appalled at the "facts" put forth in this book for those not in the field. There have been 2 subsequent versions of the DSM published since the one used by this author and another is in process. I definitely would NOT recommend this particular book. The fact that it is written by a psychiatrist makes these flaws all the more troublesome.
