Barthel ADL Index: a comparison of administration methods

Abstract

The Barthel ADL Index is routinely used to assess elderly patients after discharge from hospital. Its inter-rater reliability and criterion validity have been well established. However, the inter-method reliability in administering this scale has not been sufficiently documentated. This study compares post, telephone and interview (visit) methods of administration to investigate their agreement. The index was administered by the three methods in random order after patients were discharged from acute geriatric wards. Results suggest that these three methods are reliable and agree well with each other in the total scores obtained. Analyses of individual item scores indicate poor agreement on one item (stairs). Suggestions on improving the guidelines for this item are outlined.
