This paper describes the development and validation of a questionnaire designed to measure selfrated disability due to back pain. The questionnaire is short, simple, sensitive, and reliable. It would be suitable for use in future trials of treatment. *Department of General Practice (Lecturer), St. Thomas' Hospital Medical School, Lambeth Palace Road, London, England. †Department of Community Medicine (Lecturer in Medical Statistics), St. Thomas' Hospital Medical School, Lambeth Palace Road, London, England. © Lippincott-Raven Publishers.
