The fourth edition of Psychopathology is the most up-to-date text about the etiology and treatment of the most important psychological disorders. Intended for first-year graduate students in clinical psychology, counseling psychology, and related programs, this new edition, revised to be consistent with the DSM-5, continues to focus on research and empirically-supported information while also challenging students to think critically. The first part of the book covers the key issues, ideas, and concepts in psychopathology, providing students with a set of conceptual tools that will help them read more thoroughly and critically the second half of the book, which focuses on specific disorders. Each chapter in the second and third sections provides a definition, description, and brief history of the disorder it discusses, and outlines theory and research on etiology and empirically-supported treatments. This edition also features a companion website hosting lecture slides, a testbank, an instructor’s manual, case studies and exercises, and more.
