The validity of self-assessment predicts on-road driving performance beyond the effects of age and sex in older drivers with and without MCI
研究112名老年驾驶员发现，自我评估的有效性（是否高估或低估自身驾驶能力）能独立于年龄和性别预测实际道路驾驶表现，高估与年龄增长、认知下降和危险驾驶行为相关。
OBJECTIVES: Higher age is often seen as a key factor in the decline of driving skills. Moreover, there is some evidence that overestimation is related to both higher age and poorer on-road performance in older drivers. However, it is unknown how the extent of overestimation or underestimation affects on-road driving performance beyond age. METHODS: 112 older drivers with and without mild cognitive impairment participated in this prospective on-road study. All participants underwent a standardized on-road driving assessment, neuropsychological testing, collection of driving-related data and different self-assessments. Statistical analyses included a hierarchical regression analysis to predict on-road driving performance by adding age and sex in the first step and the validity of self-assessment (VSA) in the second step. Correlation analyses focused on the association between VSA and cognitive and driving-related behavioral factors. RESULTS: = 0.639). Moreover, the degree of overestimation correlated with higher age, lower cognitive performance and more risky driving behavior. DISCUSSION: Our results highlight the importance of the VSA for on-road driving performance beyond the effects of age and sex. Moreover, the VSA appears to decrease towards overestimation with increasing age and decreasing cognition and should thus be a focus of safety research.
