Effects of cognition on driving involvement among the oldest old: variations by gender and alternative transportation opportunities.
OBJECTIVE
This study explored the impact of cognition and the availability of other drivers on driving restriction and cessation among older adults.


METHODS
Survey data from the first wave of the Asset and Health Dynamics Among the Oldest Old data were analyzed, using multinomial logistic regressions.


RESULTS
Cognitive impairment is associated with driving restriction and cessation, although a noteworthy minority of mildly and severely cognitively impaired individuals continue to drive. Partner's driving and involvement and presence of other drivers in the household moderated the effect of cognition on driving restriction and cessation.


CONCLUSIONS
The decision processes surrounding an individual's restricting or stopping driving are complex and may include consideration not only of competence, but also of sense of self-worth and relationship with a partner.
