EVERYDAY PROBLEM-SOLVING IN OLDER ADULTS - OBSERVATIONAL ASSESSMENT AND COGNITIVE CORRELATES

Older adults' ability to solve practical problems in 3 domains of daily living was assessed using a new measure of everyday problem solving, the Observed Tasks of Daily Living (OTDL). Findings showed that the OTDL formed internally consistent scales representing 3 distinct factors of everyday problem solving. Moreover, the OTDL showed convergent validity with related scales of a paper-and-pencil test. Older adults' performance on the OTDL was significantly correlated with their scores on measures of basic mental abilities. Path analysis showed that age affected older adults' performance on the OTDL directly and indirectly via cognitive abilities. Participants' education and health affected their everyday competence indirectly through cognitive abilities. The effects of perceptual speed and memory span were mediated by fluid and crystallized intelligence.
