The authors sought to determine the criterion validity of the Useful Field of View (UFOV) assessment and Stroke Drivers' Screening Assessment (SDSA) through comparison to the results of on-road assessment. This was a prospective study with people with stroke. Outcome measures used were UFOV, SDSA, and the results of on-road assessment. Both the results on UFOV (Divided Attention subtest, p<.01; Selective Attention subtest, p<.05) and SDSA (p<.05) were significantly related to the recommendation from on-road assessment. The Divided Attention subtest of the UFOV had the highest sensitivity value (88.9%). UFOV and SDSA are valid assessments of driving ability for stroke. The Divided Attention subtest of the UFOV can guide decision making of occupational therapists in stroke driver rehabilitation and in determining those who require further assessment on road because they pose a safety risk. Screening assists people with stroke to decide whether they are ready to have an on-road assessment. (Author/publisher)
