Abstract
Purpose
To examine the factor structure and predictive utility of four instrumental activities of daily living (IADL) measures to identify cognitive status changes among older adults enrolled in the ACTIVE Trial.
Major Findings
Extracted factors represented IADL instruments. Baseline performance on the Everyday Problems Test (EPT) predicted 5-year MMSE scores (est. = .08,
Conclusions
IADL functional domains were not interchangeable across instruments. The EPT demonstrated better predictive utility compared to other instruments for detecting subsequent cognitive decline/impairment. This is a useful step in developing effective tools to detect early functional deficits indicating subsequent clinical impairment.
