The third edition of this incisive practitioner resource and course text--updated for the DSM-5 Text Revision (DSM-5-TR)--takes the reader step by step through diagnostic decision making in mental health. Guidelines are presented for evaluating information from multiple sources, constructing a wide-ranging differential diagnosis, creating a safety hierarchy, and using decision trees to derive a valid working diagnosis. The book addresses specific issues in diagnosing the conditions most often seen in mental health practice, with an emphasis on how diagnosis informs effective treatment. More than 100 vivid vignettes illustrate the diagnostic process and allow readers to practice their skills.
