Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
After participants are randomised into the intervention (Stroke Riskometer) group, a study RA will contact them and they will be provided a link to download the Stroke Riskometer Pro application on their mobile device. If required, they will be guided through the installation process to ensure that the app is working correctly on their device. After this they will be instructed to open and use the app as they see fit. Participants will not be instructed on how many times they should use the app/how often to use it to determine "real world" usage. The application requires the user to answer 20 health and lifestyle related questions, after which it provides them with a 5 and 10 year risk of stroke. In addition, the users applicable risk factors are identified, and the management section of the app provides additional information on these risk factors and the steps the user can take to minimise their impact. At the end of the study, participants will be asked how often they used the application, as well as their general thoughts about the utility of the application.

Outcomes
Primary outcome [1] 297720 0
Change from baseline in awareness about stroke risk and associated stroke risk factors. Participants will be asked to identify stroke symptoms and risk factors - and the percentage change in correct responses will be calculated.
Timepoint [1] 297720 0
6 months post baseline
Secondary outcome [1] 322010 0
Change from baseline in stroke risk. Participants complete the Stroke Riskometer questionnaire to measure their absolute 5 and 10 year stroke risk, and any change in the risk between baseline and follow-ups are measured.
Timepoint [1] 322010 0
6 months post baseline
Secondary outcome [2] 322058 0
Change in health behaviours related to stroke risk factors. Changes in the Life's Simple 7 health behaviour score are recorded to determine change in behaviour related to modifiable risk factors associated with stroke.
Timepoint [2] 322058 0
6 months post baseline
Secondary outcome [3] 322059 0
Determine feasibility of a full-scale RCT using the same intervention. A semi-structured qualitative interview will be used to ask participants about the acceptability of the intervention. This, in addition to the findings of the pilot trial will be used to inform the feasibility of conducting a full scale trial to investigate the efficacy of the Stroke Riskometer app as tool for primary stroke prevention
