Purpose. The Useful Field of View (UFOV®) test has been shown to be highly effective in predicting crash risk among
older adults. An important question which we examined in this study is whether this association is due to the ability of
the UFOV to predict difficulties in attention-demanding driving situations that involve either visual or auditory distracters.
Methods. Participants included 92 community-living adults (mean age 73.6 5.4 years; range 65–88 years) who
completed all three subtests of the UFOV involving assessment of visual processing speed (subtest 1), divided attention
(subtest 2), and selective attention (subtest 3); driving safety risk was also classified using the UFOV scoring system.
Driving performance was assessed separately on a closed-road circuit while driving under three conditions: no distracters,
visual distracters, and auditory distracters. Driving outcome measures included road sign recognition, hazard detection,
gap perception, time to complete the course, and performance on the distracter tasks.
Results. Those rated as safe on the UFOV (safety rating categories 1 and 2), as well as those responding faster than the
recommended cut-off on the selective attention subtest (350 msec), performed significantly better in terms of overall
driving performance and also experienced less interference from distracters. Of the three UFOV subtests, the selective
attention subtest best predicted overall driving performance in the presence of distracters.
Conclusions. Older adults who were rated as higher risk on the UFOV, particularly on the selective attention subtest,
demonstrated poorest driving performance in the presence of distracters. This finding suggests that the selective attention
subtest of the UFOV may be differentially more effective in predicting driving difficulties in situations of divided attention
which are commonly associated with crashes.
