The MAT-sf: clinical relevance and validity.

ABSTRACT:

Background

The measurement of mobility is essential to both aging research and clinical practice. A newly developed self-report measure of mobility, the mobility assessment tool-short form (MAT-sf), uses video animations to improve measurement accuracy/precision. Using a large baseline data set, we recalibrated the items, evaluated the extent to which older patients' self-efficacy (i.e., confidence) for walking was related to MAT-sf scores beyond their actual 400-m walk time, and assessed the relationship of the MAT-sf with body mass index and other clinical variables.

Methods

The analyses employed baseline data from the Lifestyle Interventions and Independence for Elders Study.

Results

Item recalibration demonstrated that the MAT-sf scoring algorithm was robust. In a
