Abstract:
Development of a self-report measure of activity limitation that combines measures of ability with necessity is described. The history of the Milliken Activities of Daily Living Scale (MAS) is traced, and the current measure is described. The test-retest reliability and concurrent validity of the MAS is studied. The MAS is found to have excellent reliability and good validity. The utility of the instrument to guide clinical practice is described, with a discussion of the importance of client-centered self-report measures of activity limitation.
