Summary

This study evaluated the effectiveness of four distinct training interventions designed to improve the driving performance of healthy older adults. The research aimed to determine which methods could help drivers aged 65 and older maintain or enhance their on-road competence, excluding individualized rehabilitation regimes for those with specific medical conditions like stroke. The study compared four treatment groups against a control group that received neutral health and wellness counseling. The experimental design involved 100 volunteer participants recruited from a rehabilitation hospital in South Carolina, randomly assigned to one of five groups (four training types and one control). Each group received eight hours of direct contact with providers. The training interventions included: (1) classroom driver education supplemented by one hour of behind-the-wheel instruction; (2) computer-based exercises targeting visual processing speed and divided attention; (3) occupational therapy (OT)-based exercises for visual skills and attention; and (4) physical conditioning for strength and flexibility. A certified driver rehabilitation specialist, blind to the treatment assignments, conducted on-road performance evaluations at three time points: baseline, immediately post-training, and after a three-month delay. Performance was scored on 33 subscales covering strategic skills (e.g., planning, rule knowledge) and tactical skills (e.g., speed management, hazard anticipation) using an ordinal scale. The findings indicated that only the OT-based visual skills and attention training demonstrated significant gains relative to the control group for drivers who had no deficits at baseline. This group showed statistically significant improvements in maintaining performance at both the immediate post-treatment assessment (p < .05) and the delayed three-month assessment (p < .01). For the small subset of drivers with baseline deficits, both the OT-based exercises and the classroom plus behind-the-wheel training groups achieved significant improvements (p < .05) immediately after training, though no training group showed significant gains for this subgroup at the three-month follow-up. The classroom-based training yielded limited but significant gains, with participants reporting high practical value. Computer-based and physical conditioning groups did not show significant improvements in driving performance compared to the control. The study concludes that OT-based visual skills training is the most effective intervention for preserving driving competence in healthy older adults, offering a scalable solution for clinical settings. However, the authors note significant limitations, including a small sample size, restricted range of baseline driving skills, and a short three-month retention period, which raises questions about the long-term persistence of training effects. The reliance on ordinal scoring also limits statistical analysis and the ability to assess integrated driving performance. The report suggests that future research should employ more refined, interval-level measurement methodologies to better evaluate on-road driving fitness.

Key finding

Only occupational-therapy visual-skills training significantly preserved on-road performance in older drivers without baseline deficits, at p < .05 immediately after training and p < .01 at the three-month follow-up.
