This thoroughly revised edition reflects achievements not only in the basic sciences but also in their practical application, as well as changes in the organization and delivery of health care. It covers the full range of treatments for mental illness, including psychoanalysis, behavior therapy, cognitive therapy, interpersonal therapy, and other brief therapies. Studies of different forms and combinations of treatments continue to refine and individualize approaches to the particular patient. To make all of this meaningful to mental health professionals and to those outside that field who are interested in what psychiatry is doing to meet the needs of patients, the editor has retained the encyclopedic approach to the definition of important terms. The eighth edition will be invaluable to psychiatrists and neurologists (and their students and trainees), to psychologists, nurses, social workers, counselors, lawyers, claims reviewers, and to the lay reader.
