This is a thoroughly updated and revised edition of Measuring Disease. It supplements the author's previous work Measuring Health (2nd edition). In assessing the outcome of disease and treatments, measurement scales must be relevant to their specific effects, necessitating the use of disease specific questionnaires. There is now considerable interest in measures which are multi-dimensional, and which are more sensitive than generic measures to specific disease and treatment effects. This book reviews disease specific measures of quality of life and, where relevant, popularly used symptom and single dimension scales. It is intended as a source book for researchers, medical and health care practitioners who are involved in the measurement of the outcome of health services.
