Driving is the preferred transportation method for many older adults, but age-related cognitive decline can limit time spent behind the wheel. Empowering older adults to be more mobile drivers (that is, driving more frequently and for longer distances) is critical to boosting physical, social and cognitive wellness, according to new research.

The researchers surveyed 895 drivers (mean age, 71; 57%, women). Regular drivers older than 65 were included, and those with significant, untreated impairments and high alcohol consumption were excluded. Participants self-reported their driving habits and histories, took an objective cognitive assessment, and completed a subjective questionnaire to evaluate wayfinding ability.

More than 80% of those surveyed reported using navigational assistance. Of these, more than half used a GPS for some trips, as opposed to rarely or for all trips; more than 70% used a GPS for entire journeys; and fewer than 3% reported using a GPS for every trip.

Among participants with poor objective wayfinding abilities, those who used a GPS reported greater driving mobility than those who did not use a GPS. Individuals who self-reported having a worse sense of direction also showed greater reliance on using a GPS when driving.

The researchers recommend integrating navigational assistance into strategies for promoting older adults’ driving independence. “In older age, driving is vital for quality of life and wellbeing,” the authors wrote. “Our study shows that older drivers with worse spatial abilities who use GPS navigation assistance have better driving mobility, and therefore supporting older adults in using these tools can help them maintain their driving.”
