ABSTRACT

Objective : CPAD (Cognitive Perceptual Assessment for Driving) is a computer-based evaluation tool developed to test cognitive-perceptual skills necessary for driving. The objective of this study is to evaluate driving ability of persons with brain injury using CPAD and analyze associated factors. Methods : 187 brain damaged persons who were referred for driver evaluation underwent clinical evaluation including CPAD. Data were collected and analyzed on the 182 out of the 187 whose CPAD test was finished. Results : Among 187 participants, 34.8% passed CPAD test, 21.9% failed, 40.6% got borderline score, and 2.7% could not finish the test. Failed participants were significantly older in age than either borderline or passed participants. Those who had poor motor recovery showed significantly lower pass rate(22.1%) and higher fail rate(28.4%) than those with better motor recovery (pass 50.7%, fail 11.3%). Conclusion : Driver evaluation using CPAD could determine whether brain damaged persons’cognitiveperceptual skill is sufficient for driving or not. However, there needed further evaluation and research which could find out safe driving ability.
