10 questions measuring daily living activities of chronic pain patients were developed for 30 chronic pain patients. Test-retest reliability was .89, and internal consistency was .75. Validity, measured by global ratings (r = .63) and those by significant others (r = .77) was satisfactory. This Activities of Daily Living Scale seems to be reliable and valid for use in clinical and research settings.
