Abstract
The conventional way to assess the driving ability of older drivers is to administer a standard driving test. Less expensive diagnostic alternatives are being sought as replacements. A representative sample of 49 elderly drivers, referred for a driving diagnosis and possible license renewal, was given two paper-and-pencil tests of cognitive functioning: the Motor-Free Visual Perceptual Test (VISUAL) and the Clock Drawing Task (CLOCK). Both instruments have been used as "screening tool[s] in identifying those who are unfit to undergo an on-road evaluation" (Korner-Bitensky et al., p. 253). The data were analyzed with Wright's Rasch regression model. The VISUAL and CLOCK variables were co-calibrated and anchored to define a two-test unidimensional, reproducible, and stable yardstick. The Driving Diagnosis was then added as a dichotomous item.
