Abstract:

Background/Context: Older adults' ability to drive is important for maintaining independence and community mobility; for most, driving supports aging in place of their choice. Many older drivers notice changes in their behind-the-wheel abilities and will adapt how often and where they drive to reduce their collision risk. Approaches to improve their on-road performance have included showing them videos of their actual behaviour alongside receiving feedback from driving instructors. However, the most effective type and intensity of this feedback, as well as older adults' perceptions of such approaches, have not been determined.

Aims/Objectives: The current study examines the effectiveness of a customized video-based feedback intervention on improving older drivers' actual and perceived on-road performance. Methods/Targets: Community-dwelling healthy older adults (n=70; aged 65+) were randomly assigned to receive either video-based feedback of their actual driving or a placebo (i.e., healthy-aging video). Both participants and driving assessors were blinded to study allocation. Primary study outcomes focused on changes in on-road performance (i.e., number of driving errors) and perceived abilities (i.e., driving confidence, situational avoidance). Participants were also interviewed for their perspectives of receiving the intervention.

Results/Activities: Participants reduced driving error scores at follow up and were more aware of changes in their driving abilities. Feedback provided by the driving instructor ranged from suggestions to remediate driving errors to validation of appropriate behaviours. Recommendations were individualized to each participant but could also be generalized across older adult participants.

Discussion/Deliverables: By examining the effectiveness of this video-based approach, researchers, policy makers and health care providers will have a better understanding of who might benefit the most from such feedback (i.e., the ideal participant) in terms of age group, driver gender, baseline driving confidence or driving experience.

Conclusions: Study findings inform the development of an innovative older driver refresher program that opens the conversation about driving and other transportation alternatives aimed at supporting their out-of-home engagement and safe mobility for as long as possible.
