"If DSM-5-TR is the encyclopedia, this book is the manual. Morrison shows you real diagnosing - the thinking processes, integration of data, case formulation for treatment, and so on - not just assigning labels and ICD-10-CM codes. Reading this book is like sitting with a wise and experienced clinician showing you how to weigh and balance the evidence. Even the introductory explanations of how to use the book are excellent guides for teachers and students and will greatly enhance learning. Over 130 superbly constructed cases show exactly how Morrison applies the DSM-5-TR rules and logic. The cases bring the criteria sets and checklists of DSM to life. This book is suitable as a text in introduction-to-the-profession courses in clinical fields. Anyone reading it will feel like (and become) a smarter clinician." - Edward L. Zuckerman, PhD, author of Clinician's Thesaurus
