Some of the disorders defined in DSM-IV, such as the Substance-Related Disorders and the relatively new diagnosis of Posttraumatic Stress Disorder, bear a razor! -sharp specificity and resemblance to reality. The well-established Psychotic Disorders, often considered the most severe type of mental illness, and the Mood and Personality Disorders, which the meat and potatoes of psychiatry, will no doubt continue to evolve, and I will look forward to seeing the next edition of this exciting book.
Not to be missed are the delightful appendices, which include such gems as the Defensive Functioning Scale and a number of tentative "investigational criteria sets - descriptions of disorders which are not presently diagnosed (officially) but which may be in the future.
