Abstract

OBJECTIVE
We tried to evaluate the driving ability of stroke patients using Cognitive Behavioral Driver's Inventory (CBDI), Psychological Software Service, U.S.A. to find out whether it is helpful in predicting the outcome of driving rehabilitation. METHOD: Subjects were 18 stroke patients who had driven a car before the stroke. Each patient was evaluated with CBDI and got a driving test. We compared driving test results with CBDI scores. RESULTS: Average CBDI score was 63.0 +/- 19.3. There was no significant difference according to lesion sides or types of stroke. Average score of driving test was 85.3 +/- 10.9. Twelve of 18 subjects passed the driving test and six subjects failed. Average score among right hemiplegics was significantly higher than that of left hemiplegics (p<0.05). Average CBDI score of the subjects who passed the driving test was 52.3 +/- 4.7, while that of the failed subjects was 84.7 +/- 19.6. There was significant difference in CBDI score between 2 groups (p<0.05). Among the 28 items of CBDI, 11 items including brake reaction time, Wechsler Adult Intelligence Scale-Revised Picture Completion showed significant correlation with the total score of the driving test (p<0.05). CONCLUSION: CBDI can be used as a useful tool for predicting driving ability of stroke patients.
