Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Driver Safety Behaviour Change Program – a driver safety behaviour change program consisting of an online self-assessment of driving risk questionnaire, a group session regarding driving patterns and behaviour (known as group session 1), an on-road coaching session, and a final group session regarding driving patterns and behaviour (known as group session 2). The self-assessment questionnaire takes approximately 20 minutes to complete, both group session 1 and group session 2 take 3 hours, and the on-road coaching session takes 2 hours. The timings between each course session are as follows: the self-assessment questionnaire is completed within 0-14 days of the participant attending group session 1, the on-road coaching session is completed 7 days after group session 1, and group session 2 is completed within 14 days of attending the on-road coaching session. All group sessions and on-road coaching sessions are facilitated by trained instructors who are employed by the Centre for Adult Education (CAE). The CAE are contracted to VicRoads to deliver the training program in Victoria and NSW. The intervention is being undertaken with new drivers in Victoria (randomised control trial (RCT)/Quantitative Trial) and new drivers in New South Wales (NSW) (Process Trial). There are no differences in the intervention between Victoria and New South Wales participants – there are no control participants recruited in New South Wales.

Comparator / control treatment
Control group is active, they are asked to complete three surveys which are completed at the same time as the Treatment participants. The survey timings are: pre-program (between 30-90 days after obtaining P1 licence), 1-month post-program, and 12-months post-program. The surveys take ~20 minutes to complete and are all administered online. The surveys cover the following areas: Self-reported crashes, self-reported driving exposure, driving behaviour (based on Driver Behaviour Questionnaire), driving style (based on 11 items using visual analogue scales), awareness of accident risk factors (5 items out of a possible 22 items are selected as the factors that are most important in causing serious accidents – this question is repeated using the same 22 items for the least important factors), and the key ingredients for behaviour change are measured via self-efficacy, outcome expectancies, subjective norms, and intentions The control group is only relevant for the Victorian trial, that is in New South Wales only Treatment participants are recruited because the New South Wales sample of participants are evaluated via the Process Evaluation whereas the Victorian participants are evaluated via the Quantitative Evaluation.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by computer for all Victorian participants (this is applicable to Victorian participants only as NSW are all allocated to the Treatment arm for Process Evaluation)
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation).
