Complex real-world functioning and neuropsychological test performance in older adults.

Overview

In stepwise regression analyses with Independent Living Scales (ILS) summary and subscale scores as the dependent variables, 8 of 10 psychometric measures from our battery for older adults emerged as important predictors for 69 patients referred for clinical assessment. The Dementia Rating Scale (DRS) score entered first for 6/8 analyses. However, measures of confrontation naming, oral reading, verbal fluency, paragraph recall, visual perception, complex attention, and depression also added explanatory power. Multiple Rs ranged from .66 to .88 except for the Social Adjustment subscale, which correlated only with the depression scale.
