Relation of Useful Field of View and other Screening Tests to on-Road Driving Performance

Abstract

The purpose of this study was to examine the value of a clinical driving assessment battery in predicting performance on an on-road driving test. 43 participants referred to the Bryn Mawr Rehab Adapted Driving Program for evaluation of driving ability underwent an evaluation consisting of a predriver screening and an on-road driving test. The predriver screening included a vision screening, a reaction time task, a split-attention task, the Hooper Visual Organization Test, verbal and symbolic sign recognition, and assessment of Useful Field of View. Logistic regression analyses were applied to identify which predriver screening variables could be used to predict outcome on the on-road driving test (pass/fail); UFO® was that best single predictor. The addition of screening tests beyond UFOV® alone did not increase predictive validity. These findings suggest that UFOV® may serve as an indicator of the need for further driving assessment.
