In a fully revised and expanded second edition, this landmark work brings together in one volume the most important current theories of personality disorder. Written by the theorists themselves, all of the chapters have been extensively rewritten to reflect a decade's worth of significant research developments, and two entirely new chapters have been added. Comprehensive and authoritative, this is an indispensable resource and text in a rapidly developing field.<BR>Experts from across the theoretical spectrum present their respective approaches, including psychodynamic, interpersonal, attachment, ecological, psychometric, and neurobiological perspectives. Following a consistent format to facilitate reference and comparison, each chapter explicates the core assumptions of the theory at hand and reviews the extent to which it has been validated by empirical research. Coverage includes the ways in which each theory enhances our understanding of causation, classification, mechanisms, and risk factors of personality pathology, as well as how it has contributed to measurement, diagnosis, and treatment. The volume also explores similarities and differences among the various theories and identifies potential avenues of integration.<BR>This volume belongs on the desks of clinicians, researchers, and students in clinical psychology, clinical social work, and psychiatry. It serves as a uniquely informative text in advanced undergraduate and graduate-level courses.
