Nearly forty years after its original publication, one of the most influential textbooks on modern pain management is available again for today's generation, in a unique and enhanced edition. Now complemented by expert, chapter-by-chapter commentaries from leading authorities on psychologically-oriented pain management and pain-associated disability, Fordyce's Behavioral Methods for Chronic Pain and Illness blends Dr. Fordyce's pioneering behavioral concepts with modern research and clinical practice. This innovative title is ideal for clinicians and researchers involved in the multidisciplinary assessment, treatment, and management of pain and pain-associated disorders, as well as anyone interested in behavioral approaches to chronic pain and illness. Throughout his long and illustrious career, Wilbert Bill Fordyce made major contributions to the health and well-being of those who suffered from chronic illnesses. As a clinical psychologist working in rehabilitation medicine, he put health psychology on the map for those who had chronic pain and began the cognitive/behavioral approach to pain management. Excelling in research, teaching, and patient care, he was a founding member of the International Association for the Study of Pain IASP and the American Pain Society APS, lectured worldwide, and received numerous awards and honors in his field. His seminal book, Behavioral Methods for Chronic Pain and Illness, was originally published in 1976 and opened a new era in the diagnosis and treatment of chronic pain. This republication with contemporary commentaries is an indispensable resource for a biopsychosocial approach to the management of chronic pain.
