Development and pilot testing of an assessment battery for older drivers.
BACKGROUND
The purpose of the study reported here was to develop and pilot test a comprehensive battery of assessment instruments for older drivers that would be inexpensive and easy to administer so that it could be used in longitudinal studies.


METHODS
The resulting battery was developed by selecting a set of validated assessment instruments and combining them into a package, with a total acquisition cost of less than $900. As part of this battery, three questionnaires were developed utilizing items from established questionnaires with minor modifications. The battery was pilot tested with a convenience sample of 38 drivers aged 65 years or older.


RESULTS
Results showed that the entire battery required less than one hour to complete. Data from the assessment outcomes fell within normative ranges. Feedback from subjects indicated that the battery was acceptable, free of problems, presented tasks in a good order, and was not too long.


CONCLUSIONS
Based on study findings, the assessment battery appeared to be low-cost, transportable, easy to administer, easy for subjects to complete, provides a comprehensive assessment of a person's physical health, mental health, and driving behaviors, and would serve as a valuable data collection tool for a longitudinal study of older drivers. Such a longitudinal study is needed in order to answer some of the most important questions about older driver safety and mobility.
