Abnormal Psychology, also called Psychopathology, is a standard course for psychology majors and a popular elective for students of criminal justice, business, education, sociology, and other fields taught at both 2- and 4-year colleges. Balancing biological, psychological, and social and cultural approaches, Barlow and Durand's ground-breaking integrative approach to abnormal psychology is the most modern, scientifically valid method for studying abnormal psychology. In this Fourth Edition of their proven ABNORMAL PSYCHOLOGY, David Barlow and V. Mark Durand successfully blend sophisticated research (including new prevention coverage) and an accessible writing style with the most widely recognized method of discussing psychopathology. Going beyond simply describing different schools of thought on psychological disorders, the authors explore the interactions of the various forces that contribute to psychopathology. A conversational writing style, consistent pedagogical elements, integrated case studies (95 percent from authors' own files), video clips of clients (on the free accompanying ABNORMAL PSYCHOLOGY LIVE CD-ROM), and additional study tools make this text the most complete learning resource available. For instructors, an Instructor's Resource Manual, Test Bank, and a wide selection of videos are available to use when teaching the course. See the Supplement descriptions for more details.
