For nearly four decades, Abnormal Psychology: The Science and Treatment of Psychological Disorders has been a trusted resource for instructors and students. Known for its comprehensive coverage of current research, the book consists of a balance and blending of research and clinical application, and involves the learner in the kinds of real-world problem solving engaged in by clinicians and scientists. Students learn that psychopathology is best understood by considering multiple perspectives which provide the clearest accounting of the causes of these disorders as well as the best possible treatments. This International Adaptation features a new integrated approach, shining a light on psychopathologies' root causes and most effective treatments by approaching these disorders from multiple, complementary perspectives underscoring that very often biological, cognitive, behavioral, and socioemotional factors are critical to understanding psychological disorders. This edition includes new cases and data from regions such as Europe, South America, Africa, and Asia Pacific which present a more encompassing view of the clinical context for the theories and research that occupy most of our attention in the book.
