Summary

This study addresses the challenge of maintaining mobility and safety for older drivers, a demographic projected to comprise one in five U.S. residents by 2030. While age alone does not determine driving safety, age-related declines in physical and cognitive abilities can impact driving behaviors. The research aimed to validate and adapt a Visual Scanning Training (VST) program previously shown to have promising results when delivered by Certified Driver Rehabilitation Specialists (CDRSs). The primary objective was to develop a modified VST protocol that could be administered by generalist occupational therapists (OTs) in an office setting, thereby increasing accessibility and reducing costs. To achieve this, the researchers removed the on-road training component from the original protocol, as generalist OTs are not permitted to conduct behind-the-wheel sessions without hiring external driving schools, which would hinder widespread adoption. The study involved 89 active drivers aged 70 to 100. Researchers evaluated the effectiveness of the modified VST by comparing treatment participants to a control group. Data collection included CDRS-administered road test scores and video-coded glance behavior during evaluations, measured at pre-training, immediate post-training, and three-month post-training intervals. The researchers hypothesized that trained drivers would demonstrate improved performance in complex driving tasks, such as negotiating intersections, and exhibit increased frequency and duration of glances away from the forward view. Additionally, questionnaire responses were collected to assess participants’ perceptions of the program’s value. The findings did not support the primary hypotheses. Statistical analyses revealed no significant differences in driving performance or scanning behavior between the treatment and control groups at either post-intervention assessment. The authors attribute these null results to several limitations in the research design. First, the absence of on-road training likely diminished the participants’ ability to transfer skills learned in clinical exercises to actual driving contexts. Second, the interactive nature of the CDRS evaluation, which involves conversation to assess divided attention, may have interfered with the application of newly learned scanning behaviors. Finally, the artificial context of the evaluation may have discouraged the use of new skills, suggesting that naturalistic data collection might have yielded different outcomes. Despite the lack of measurable improvement in objective performance metrics, participants reported high satisfaction with the program. Questionnaire responses indicated that drivers felt the training would help them drive more safely, with many willing to recommend the program and pay up to $50 for it. The study concludes that while the specific modified protocol did not demonstrate efficacy in this controlled setting, the development of a complete, affordable, and replicable curriculum delivered by generalist OTs represents a significant strength. The authors suggest that the platform may merit further evaluation in applications unconstrained by the limitations identified in this study, particularly those that might better facilitate the transfer of training to real-world driving environments.

Key finding

The modified visual scanning training program delivered by generalist occupational therapists did not produce statistically significant improvements in driving performance or visual scanning behaviors compared to a control group.
