Test acceptability and confidence levels in older adults referred for fitness-to-drive evaluations

In this study, we examined confidence and face validity or client acceptability of tests used in a Veterans Affairs Medical Center driving clinic. The clinic used evidence-based off-road tests and adopted the Washington University Road Test (WURT) as a performance-based on-road examination. Forty-three clients consented to participate in the study; most were male with an average age of 78.2 years (standard deviation = 12.6). In general, a trend existed toward higher client acceptability of tests adopted from the Neuropsychological Assessment Battery (Stern & White, 2003) and the WURT than of other off-road measures. Confidence decreased after administration of the psychometric test battery, yet it increased after the on-road evaluations despite a 47% failure rate in the sample. Additional study is needed on test acceptability because it may have the potential to increase understanding, compliance, or both with driving recommendations. Additional research is also needed to examine client confidence levels and their potential impact on performance during the driving evaluation process.
