To examine the psychometric properties of the Driving Awareness Questionnaire (DriveAware) and to compare this rating of awareness of driving ability with the rating made in the context of an on-road assessment.
A prospective design was employed to examine the psychometric properties of DriveAware using Rasch analysis. Participants (n = 91) with varying diagnoses were recruited from two driving rehabilitation centres in Sydney, Australia. They completed DriveAware in the context of a standard driving assessment. Awareness of driving ability determined by DriveAware was compared with awareness determined in the on-road assessment.
Rasch analysis provided good evidence for construct validity and inter-rater reliability and some evidence for internal reliability of DriveAware. The item hierarchy was logical and goodness-of-fit statistics for four of five items were within an acceptable range. The test had a moderate reliability index (0.73). Measurement precision could be improved by including more items to assess drivers with little awareness. When compared with the on-road measure of awareness, the best DriveAware cut-off score yielded sensitivity of 84% and specificity of 94%.
This short and easy-to-administer test could provide a useful tool with sound psychometric properties to measure awareness of driving ability.
检验驾驶意识问卷（DriveAware）的心理测量特性，并将这种对驾驶能力的认知评分与在道路评估背景下做出的评分进行比较。
采用前瞻性设计，使用拉施分析来检验DriveAware的心理测量特性。从澳大利亚悉尼的两个驾驶康复中心招募了诊断各异的参与者（n = 91）。他们在标准驾驶评估的背景下完成了DriveAware。将DriveAware确定的驾驶能力认知与道路评估中确定的认知进行比较。
拉施分析为DriveAware的结构效度和评分者间信度提供了充分证据，并为其内部信度提供了一些证据。项目层次结构合理，五个项目中有四个的拟合优度统计数据在可接受范围内。该测试的信度指数适中（0.73）。通过纳入更多项目来评估意识淡薄的驾驶员，可以提高测量精度。与道路认知测量相比，DriveAware的最佳临界值得分产生的敏感度为84%，特异度为94%。
这个简短且易于实施的测试可以提供一个具有良好心理测量特性的有用工具，用于测量驾驶能力认知。
