Development of a Web-Based Resource to Support Driving Safety in Older Adults: Semistructured Interview and Focus...

Older adults face increased crash risk due to age-related declines in cognitive, visual, and physical functioning; yet, many Australians in their 70s are continuing to drive. Web-based platforms are increasingly used to deliver health and mobility information to older adults and may support safer driving; however, existing online resources on driving safety often lack age-specific guidance, have usability limitations, and may not be designed with older adults in mind.

This study aimed to explore the information needs, preferences, and experiences of older drivers and general practitioners (GPs) to inform the formative, prelaunch development of a user-centered web-based platform, Ageing Well on the Road. Interviews and focus groups were conducted to gather feedback on content, accessibility, and usability, with data collection guided by the Consolidated Framework for Implementation Research and the Technology Acceptance Model frameworks to explore implementation and technology adoption factors.

Website development was informed by a review of 26 Australian websites and consultations with stakeholders. Semistructured interviews were conducted with 7 older adults (aged >67 years; one additional participant completed only survey data) and a focus group with 10 GPs experienced in fitness to drive assessments for older drivers. Thematic analysis was used to explore participants' experiences with online driving information and feedback on content, usability, and accessibility. Formative feedback from these users directly informed content and design refinements before public launch.

The website addressed priority topics, including age-related health conditions affecting driving, licensing requirements, vehicle safety features, and strategies for maintaining driving confidence. Older adults valued large fonts, plain language, intuitive navigation, and trustworthy, practical advice. GPs highlighted the website's potential to support clinical discussions around driving capacity and safety. Barriers to engagement included digital literacy limitations, accessibility concerns, and uncertainty about online information credibility.

A co-designed, web-based platform tailored to older adults and clinicians can enhance access to relevant, trustworthy information and support driving self-regulation. Involving end users in the development process is critical to optimize usability and ensure the resource aligns with their needs, highlighting the value of theory-informed, user-guided development for digital health resources.
