The third edition of "Comprehensive Handbook of Psychopathology" provides comprehensive coverage of theoretical, research, and clinical positions in psychopathology. Extensively revised and updated, this edition: outlines a highly improved classification scheme based on DSM IV; includes two new chapters on schizophrenia which reflect renewed interest in this topic, particularly from a biological basis; puts new emphasis on cultural and developmental issues; and contains increased coverage of the overlap of medicine and abnormal behaviour. With emphasis on empirical and research data that should be useful to graduate students and practising clinicians in the mental health profession, particularly clinical psychology, psychiatry, psychiatric nursing, and social work, this handbook is an ideal reference source.
