Abstract

There has been a substantial growth in research attempting to predict accidents and performance in older drivers. The Roadwise Review and the substantively identical Driver Health Inventory have been reported to provide a valid and cost-effective means of assessing crash risk in older community- dwelling adults. We administered the DHI to a community-dwelling sample of older (45 - 85 years) drivers. We also asked them to report on the difficulties they experienced while driving and on the frequency and type of crashes and moving violations the experienced in the previous two years. Results indicated on several of the tests there are substantial floor or ceiling effects, as well as barriers to usability and acceptance. Low inter-test correlations are consistent with the notion that different capacities are being indexed with the DHI. However, generally there were only low correlations between DHI performance and self-reported difficulties in driving, accidents or moving violations. While the DHI and Roadwise Review may well be valuable in providing older drivers with information on skills related to driving performance, in its current form it does not appear to be a useful tool in licensure or the prediction of driver risk.
