The most comprehensive abnormal psychology text available, Davison and Neale provide a unique balance between theory, research and case studies. Each topic is covered in sufficient depth to allow the student to achieve a complete understanding and to see that abnormal psychology changes over time, and the blend of classic and new research illustrates how the field has and will continue to evolve. Extensively revised, this fifth edition integrates DSM IIIR throughout, includes new material on the biomedical and psychoanalytic perspectives, has a major new section on epidemiological research, presents a new discussion of the problems of diagnosing personality disorders with new material on Millon's work, and includes more cross- cultural examples.
