“…In the 2 studies using DAT and control groups, 1 found a significant association [33] and the other not [40] . In a study on the effect of age, the DSST was the best predictor of driving under a single or visual double task [70] , and it was also one of the 3 significant predictive variables of ability to drive in drivers for whom a previous neuropsychological evaluation performed in a specialized setting did not make it possible to judge their fitness to drive [71] . Moreover, the DSST and Useful Field of View, a test consistently predicting a variety of driving outcomes among older and clinical populations [32,40,52,72,73] , showed similar trajectories of change over a 5-year period, and the authors suggested that both measures may reflect the same cognitive domain [74] .…”
