Comparison of self-reported crashes, state crash records and an on-road driving assessment in a population-based sample of drivers aged 69-95 years
Anstey, Kaarin J., Wood, Joanne, Caldwell, Haley, Kerr, Graham K., & Lord, Stephen R. (2009) Comparison of self-reported crashes, state crash records and an on-road driving assessment in a population-based sample of drivers aged 69-95 years. Traffic Injury Prevention, 10(1), pp. 84-90.
The study evaluated associations between outcome measures used in driving research including self-reported crashes, state crash records, and an on-road driving test (ORT).
A total of 750 community dwelling participants aged 69 to 95 were recruited via the electoral roll into a study on injury prevention. Of these, 509 were drivers, and data on self-reported crashes, and either state crash records, or an on-road assessment were available for 488. Crash history data were obtained from state records (five-year retrospective and twelve-month prospective), retrospective self-report (five-year) and prospective monthly injury diaries (twelve months). A subsample completed an on-road driving test.
During the last five years, 22.3% reported a crash, 10.0% reported a crash in the twelve-month follow-up period, 3.2% of the sample had state crash records during the previous five years, and 0.6% had state-recorded crashes during the twelve-month follow-up period. State crash records did not agree with any other outcome measure. Those who scored 5 or less on the ORT were more likely to report a crash in the past five years (55.4% vs. 36.8%; p = .009). Results did not differ when participants with probable dementia were excluded (n = 2).
The results suggest that caution should be applied when using state crash records as an outcome measure in driving research and suggest that in the Australian context, retrospective self-reported crashes over five years are preferable when objective measures of driving performance are unavailable.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
