Screening to Assessment Pathways in Evaluating Functional Cognition in Older Adults

Abstract

Identification of functional cognitive deficits can facilitate intervention to improve outcomes among older adults. We aimed to determine if impairments on screening tests of cognition are associated with deficits in performance on a more extensive functional cognitive assessment. Using a cross-sectional study design we administered the Montreal Cognitive Assessment (MoCA), the Mini-Cog, the Menu Task, and Weekly Calendar Planning Activity (WCPA) to a convenience sample of 277 community-dwelling older adults (55–93 years old). We created impaired and unimpaired groups using an established cut-off score for each screening test and compared each group on WCPA scores. The WCPA scores that demonstrated significant differences across screening measures were: Accuracy, Efficiency, Strategies, Rules, and Appointments Entered. Effect sizes for the WCPA scores Accuracy and Efficiency were large. Each screening test demonstrated discriminant validity on select WCPA scores and appear to be appropriate for use as screening tests of functional cognition.
