Abstract

We attempted to replicate the three-dimensional factor structure of a previously proposed ADL scale and demonstrate an association between the advanced ADL dimension and cognitive function. Data used in these analyses were baseline assessments of health and functional status of hospitalized patients enrolled in a randomized controlled trial of case managers as a means of reducing health care utilization. We submitted 14 items from the OARS to a two-stage process of principal components factor analysis. Four significant dimensions emerged that were remarkably similar to the advanced, basic, and household ADL dimensions reported by Wolinsky and Johnson (1991). In this sample of hospitalized patients, however, incontinence emerged as a weak fourth dimension. Multiple regression of SPMSQ mental status examination scores on these ADL dimensions demonstrates the association between cognitive function and the advanced ADL dimension. These data confirm that the underlying structure of ADLs consists of at least three separate dimensions, one of which is aligned with cognitive capacity.
