This comprehensive volume explores the role of behaviour and psychology in the development, progression, and treatment of a wide range of medical disorders, discussing in detail the health psychology application to each of the 17 ICD9 chapters of diagnostic classification. Health psychology researchers offer an applied clinical perspective in describing the prevalence, prevention, primary, secondary and tertiary treatment, and future directions for research of prevalent disorders, including infectious diseases, endocrine, metabolic, nutritional, and immune disorders, congenital abnormalities, among others. This practical sourcebook should be a useful reference for health psychologists and medical professionals and is the first of three volumes that are both comprehensive and specific as they relate to the entire field of health psychology. Topics discussed in the second and third volumes include theories, models, and philosophical underpinnings on which the field of health psychology is based as well as specific health and behavior issues facing any scientist or clinician. Although this set could be used as an encyclopedia, a manual, and a comprehensive text, it is intended to encompass a newly developing, rapidly expanding, scientifically validating, and clinically recognized area concerned with human health and healthcare delivery.
