Article / Letter to editor

Conclusion: Unless adjustments are undertaken, ADL/IADL summary scores retrieved from older persons residing in the community or residential care facilities should not be directly compared. This 15-item scale is poorly targeted for a community-dwelling older population, underscoring the need for items with improved discriminative ability. (C) 2015 Elsevier Inc. All rights reserved.
