| Popis: | 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. |
