Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
An individual education program delivered over 2 sessions (1 month apart) based on the Knowledge Enhances Your Safety Curriculum (KEYS, Stalvey & Owlsey, Copyright 1998) but adapted for the Australian context.
The sessions will be supervised by an occupational therapist. The first session will run for 2 hours and the content will be individually tailored to the participant's stage of behaviour change according to the Precaution Adoption Process Model (Weinstein et al 1998). The session is conducted in a conversational format and closely follows the educational curriculum in the KEYS program relating to vision but also includes some discussion of cognition, physical abilities and medications. The driving scenes are replaced with scenes relevant to an Australian context. The results of the DriveSafe Drive Aware (Kay, Bundy & Clemson 2009) is also integrated into the discussion. At the outset of the session an inventory of driving and weekly activities is recorded. Information about alternative transport options is provided. A set of goals will be developed during the session and strategies devised to achieve these goals.
Session 2 will be of 30 minutes duration and will involve revising some of the material and discussion of progress towards goals.

Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be a convenience sample of volunteers who meet the eligibility criteria. They will be recruited through seniors groups, flyers, community transport organisation and general medical practitioners. After screening by telephone for eligibility informed consent will be sought and a baseline assessment completed. After assessment the participant will be randomised using a concealed (web-based) process.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation scheme will be generated using an on-line random number generator (http://www.randomization.com/) and implemented through the study data base to conceal the randomisation (RedCAP) until baseline assessment is completed.
