Abstract
OBJECTIVE: To demonstrate that g-force technology can be used to help older adults with cognitive impairment improve their driving safety as part of an in-car video feedback intervention. METHOD: Unsafe driving events triggered g-forces leading to capture of video clips. The program included 3 mo of monitoring without intervention, 3 mo of intervention (weekly written progress reports, a DVD of unsafe driving events, and weekly telephone contacts), and 3 mo of postintervention monitoring. RESULTS:Mean total unsafe driving events per 1,000 miles were reduced from baseline by 38% for 9 of 12 participants during the intervention and by 55% for 7 participants during postintervention monitoring. Mean total unsafe driving severity scores per 1,000 miles were reduced from baseline by 43% during the intervention and by 56% during postintervention monitoring. CONCLUSION: Preliminary results suggest that driving safety among older drivers with cognitive impairment can be improved using a behavior modification approach aimed at problem behaviors detected in their natural driving environment.
