• Abstract:
  Statistics project that crash/injury/fatality rates of older drivers will increase with the future growth of ; this population. Accurate and precise measurement of older driver behaviors becomes imperative to ; curtail these crash trends and resulting congestion. The Comprehensive Driving Evaluation (gold ; standard test) is highly valid and reliable, but limitations include being time-consuming, providing ; limited access, and holding an element of threat (mandatory/ ethical reporting upon failing). Self-report ; is a means to identify older adults’ safe driving behaviors, increase driving safety awareness/ ; knowledge, and promote behavior change and safer driving outcomes. Existing measures are limited in ; accurately assessing older driver behaviors due to length, respondent burden, and inadequately ; representing driving constructs (i.e. person, vehicle, environment). Current self-report measures fall ; short of providing meaningful descriptions of driving ability level, and do not contribute to targeting risk ; reduction or increasing driving safety strategies. In contrast, item response theory or IRT methods are ; particularly useful to offer precise measurement of driving behaviors. Understanding a driver’s “level” ; of safe driving behaviors is a critical step towards providing an entry point for logical and effective ; interventions, identifying optimal training parameters, and predicting future driving ability. To that end ; we propose the further development of such a measure.
