Now in a revised and expanded second edition, this classic text provides comprehensive coverage of the most advanced methods for assessing the person in pain. The volume addresses the full range of issues--physical pathology, psychosocial factors, and behavioral variables--that influence patients' perception and reporting of pain, as well as their responsiveness to treatment. Leading authorities describe the available instruments and best procedures, review their limitations and advantages, and provide practical information and guidelines for assessing prevalent pain syndromes. The volume has been updated throughout to reflect the latest research findings, conceptual developments, innovative methods, and directions for future investigation. The second edition has been substantially expanded, featuring new chapters on assessment of physical functioning, family assessment, presurgical psychological screening, assessment of psychiatric disorders, diagnostic imaging, diagnostic injections, and issues related to conducting outcomes research and clinical trials. Additionally, coverage of specific syndromes has been augmented, with new chapters on neuropathic pain, complex regional pain, and chronic pelvic pain.
