Dominique graduated with a BSci. in Neuroscience and Psychology from the University of Sydney and has recently graduated with a Postgraduate Diploma in Psychology from Sturt University. Her interests in ageing and dementia have led her to work on various projects including assessment development and the reduction of dementia risk. Dominique is currently a Research Assistant on the Better Drive Study, a large randomized control trial examining the effectiveness of interventions that are key to improving older driver safety on the road.
Current road safety policy for at-risk older drivers involves ‘fitness to drive’ assessment and either license restriction or revocation. However, research indicates that there is no clear evidence that mandatory testing lowers crash rates amongst older drivers, and that driving cessation in older adults is associated with increased rates of depression, social isolation, and general health decline.
The Better Drive program includes a series of studies evaluating interventions to improve driver skill. Two trials have been completed to date.
Trial 1 used a two-arm randomised controlled trial (RCT) approach to investigate the efficacy of individually tailored driving refresher lessons against a group-based refresher course on on-road driving performance, safety and crash risk in older adults. Findings indicate that although classroom based road rules workshops for seniors can lead to improvements in on-road driving skill, the inclusion of tailored driving instruction can significantly enhance safety and reduce crash-causing on-road errors relative to classroom based workshops alone.
Trial 2 used a two group (training, no-contact control) non-randomised design to examine the transfer of computerised speed of processing (SOP) training gains to cognitive measures that are known predictors of driving safety in older adults. Findings indicate that SOP training effects can be achieved with self-administered, online training at home, with some transfer to other known cognitive predictors of driving safety. However, differential effects of training may be observed for tasks requiring goal-directed search strategies rather than diffuse attention.
A third trial is currently underway. This trial uses a three-arm randomised controlled trial approach to assess the effectiveness of computerised cognitive training and tailored on-road skills training on driver safety in older adults. Data collection for this trial will be completed in 2019.
The Better Drive program has been funded by the NRMA Road Safety Trust.
