Since 1948, this distinguished textbook has been considered the most comprehensive in its field. While this academic foundation remains in the 12th edition, new topics, fresh insights, and sharper focus on research in psychopathology have emerged. The author team offers students the most thorough explanation of psychopathology possible, and in doing so they create a learning experience that invokes thought, increases awareness, and takes students to levels of understanding that other books do not offer. The 12th edition of this book features a striking new design, updated feature boxes and case studies, the most current research findings, and an esteemed new author, Jill Hooley of Harvard University. Jill Hooley is an experienced psychopathology researcher and Director of Clinical Psychology at Harvard. She brings a fresh perspective and an exceptional background in clinical training and research, particularly in schizophrenia, to the 12th edition of this book.
