The Useful Field of View(®) (UFOV) and Trail Making Test Part B (Trails B) are measures of divided attention. We determined which measure was more accurate in predicting on-road outcomes among drivers (N = 198, mean age = 73.86, standard deviation = 6.05). Receiver operating characteristic curves for the UFOV (Risk Index [RI] and Subtests 1-3) and Trails B significantly predicted on-road outcomes. Contrasting Trails B with the UFOV RI and subtests, the only difference was found between the UFOV RI and Trails B, indicating the UFOV RI was the best predictor of on-road outcomes. Misclassifications of drivers totaled 28 for the UFOV RI, 62 for Trails B, and 58 for UFOV Subtest 2. The UFOV RI is a superior test in predicting on-road outcomes, but the Trails B has acceptable accuracy and is comparable to the other UFOV subtests.
视野测试(®)(UFOV)和连线测试 B(Trails B)是注意力分配的衡量指标。我们确定了在预测驾驶员道路表现方面哪种衡量指标更准确(N=198,平均年龄=73.86,标准差=6.05)。UFOV(风险指数[RI]和分测验 1-3)和 Trails B 的受试者工作特征曲线显著预测了道路表现。与 Trails B 相比,UFOV RI 和分测验,仅发现 UFOV RI 和 Trails B 之间存在差异,表明 UFOV RI 是道路表现的最佳预测指标。UFOV RI 对驾驶员的误分类总计为 28,Trails B 为 62,UFOV 分测验 2 为 58。UFOV RI 是预测道路表现的更好测试,但 Trails B 具有可接受的准确性且与其他 UFOV 分测验相当。
