Annotation	Self-reported capability in physical functioning has long been considered an important focus of research for older people. The authors report development of a physical functioning questionnaire that assessed difficulty of performing 48 common daily tasks, and which they tested with 150 racially and ethnically diverse people aged 60+ who had a range of functional limitations. Analyses resulted in a 32-item function component with three dimensions: upper extremity, basic lower extremity, and advanced lower extremity functions. Expected differences in summary scores of known-functional limitation groups support its validity. Test-retest reliability over a 1- to 3-week period was extremely high. The Late-Life Function and Disability Instrument has potential to assess activity concepts related to upper and lower extremity functioning across a wide variety of daily physical tasks and individual levels of physical functioning.
