This scientific poster presents a study that is part of a larger effort to evaluate a self-assessment tool for older drivers, called the "Driving Decisions Workbook". The authors sought to determine the extent to which decisions about planned driving-related behaviours (for example, driving compensation, driver retraining, clinical evaluation), reported by subjects after completing the workbook, were related to actual on-the-road driving performance. A sample of 99 licensed Michigan drivers aged 65 and above completed the workbook, as well as a short follow-up questionnaire on driving-related decisions and a standardised on-the-road driving course scored by a trained evaluator. It was shown that questionnaire responses correlated significantly with driving course scores. The strongest correlation was found for the questionnaire item about how often subjects pass up opportunities to do things such as go shopping or visit friends because of concerns about driving. It can be concluded that self-reported decisions about planned driving-related behaviours were related to actual on-the-road driving performance. Questionnaire results suggest that the workbook may be a valuable tool for self-assessment among the older driver population.
