Abstract

The purpose of this study was to examine the utility of specific tests of executive functioning for predicting instrumental activities of daily living (IADLs) in community-dwelling older individuals (n = 30). In addition to tests of frontal and executive functioning, performance-based and caregiver-rated evaluations of IADLs were obtained. Results indicated that different tests of executive functioning were associated with outcomes on performance-based versus caregiver-rated assessments of IADLs. Specifically, the Trail Making Test (Part B) made a significant and unique contribution to the prediction of performance-based IADLs. In contrast, verbal fluency performance and Trail Making Test performance made significant independent contributions to the prediction of IADLs as reported by a caregiver. These findings suggest that different aspects of frontal and executive functions may be related to IADLs, depending on the type of assessment instrument used.
