Driving is more than pedal pushing.

The purpose of this study was to determine the usefulness of neuropsychological assessment for predicting driving competency (as opposed to driving skill). Participants were divided into 2 groups, currently driving and not currently driving, based on patient and family member reports of driving ability. In addition, driving participants were only included if there had been no accidents or driving-related injuries in the past year. Stepwise discriminant function analysis was utilized to identify measures that were predictive but not redundant, thereby resulting in a shortened battery. The discriminant function analysis was able to correctly classify 94.4% of the overall sample. A factor analysis was used to identify the constructs that comprised the final short battery. In conclusion, this study demonstrated that a short neuropsychological battery was able to identify individuals who were competent to drive and those who were not competent to drive.
