Despite their common use, there are limited data on the properties of eADL scales. Where data are available there are potential methodological issues in the studies.Implications for RehabilitationThe functional abilities of older adults are most commonly measured using extended activities of daily living scales (eADL).There are many eADL scales available to clinicians and no guidance on a preferred tool.Despite the frequent use of eADL scales in research and practice, there is limited published literature on their psychometric properties (for example validity, reliability and responsiveness).The Lawton Scale has the most supporting evidence and its properties are generally acceptable, more research is needed on other eADL scales.
