Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Love Your Brain digital platform comprises access to an online course, text messages (via SMS or email), or a minimal control arm over a period of 12 weeks following a Stroke Foundation StrokeSafe presentation (online or in-person). All participants will complete a survey at baseline to identify risk factors for stroke they would like to learn more about over 12 weeks. Participants will then be randomised to one of the three arms. Following the 12 week intervention period, participants will receive a link to the 12-week completion survey and evaluation survey. Baseline and 12-week surveys should take around 20 minutes to complete.
Participants randomised to one of the two intervention groups (online course or text messages) will receive 12 weeks of information about stroke including definition and epidemiology of stroke, signs of stroke, a general overview of risk factors for stroke, specific information about risk factors for stroke chosen by the participant, and an action plan.

ONLINE COURSE
To complete the online course, participants must complete seven core modules, and at least two (of nine) elective modules over the 12 week intervention period. Modules are self-paced and to be completed within eight weeks of initiating the first module.
Core modules are 1. Introduction, 2. What is Stroke, 3. Stroke Numbers, 4. Signs of stroke - F.A.S.T, 5. Risk factors for stroke, 6. Action Plan, and 7. Completion Module. Each participant will then elect (or be guided based on the baseline survey responses) to complete at least one module based on biomedical risk factors for stroke (specifically either Blood Pressure, Cholesterol, Atrial Fibrillation, Overweight & obesity, Blood sugar & diabetes); and at least one module based on lifestyle-based behavioural risk factors for stroke (specifically Smoking, Diet & Alcohol, Exercise, Sleep & wellbeing). Modules include short videos with transcripts, text, links to further information, and knowledge quizzes. Module duration ranges between 30 minutes to 1 hour, with the complete course being achievable in 4 hours.
Online course initiation, progress and completion will be monitored. Online course analytics include
• Amount (dose) of the intervention delivered (measured by the time spend engaging with the online course, or time spent self-reported in the 12-week survey)
• Number of participants who started, completed or failed to complete the online course
• Metrics pertaining to the intervention arm engagement (e.g. link clicks, online course quiz completions).

TEXT MESSAGES
Participants in the text message arm will receive between 28 and 58 text messages over the 12 week intervention period. The text messages are in plain language with the vast majority (98%) receiving a readability index of Grade 10 or less (79% <=Grade 8). Links to additional resources are provided in some messages. The majority of text messages are the typical length of 160 characters. However, a few are longer and may appear as two messages sent one second after the other. Text message content has two elements: core information and healthier choices.
Core information is received by all participants, and includes administration (Introduction/Completion), Stroke numbers, What is stroke, Signs of stroke, Impact, Risk factors for stroke, and Action plan.
Healthier choices is personalised to the participants. The number of healthier choices the participant chooses in the baseline survey will determine the number of text messages they receive (e.g. participants who choose to learn more about one healthier choice receive messages twice per week). Risk factors will be ranked on a hierarchy of selection based on the population attributable risk. Participants will be offered the opportunity to change their preferences at any time during the 12 weeks. Options include: Control blood pressure, Start exercising and keep active, Control cholesterol, Healthy eating, Achieve and maintain a healthy weight, Quit and stay smoke free, Be informed and manage atrial fibrillation, Drink less alcohol, Control blood sugar, and Improve wellbeing and get enough sleep.
Documentation and metrics will be used to monitor participants, including:
• Amount (dose) of the intervention delivered (measured by the number of text messages received per week, or time spent self-reported in the 12-week survey)
• Number of SMS messages that failed to send
• Metrics pertaining to the intervention arm engagement (e.g. link clicks)

Behaviour
Comparator / control treatment
Participants randomised to the minimal control arm will receive three administrative emails (welcome, invitation to complete the 12-week survey, and thank you), and five generic emails about risk factors for stroke and links to information on the Stroke Foundation website. These emails will be delivered approximately every fortnight. Following the 12 week trial period, participants will receive a link to the 12-week completion survey and evaluation survey.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by computer. Allocation concealment will be conducted using the randomisation module in REDCap (https://cri.uchicago.edu/wp-content/uploads/2020/02/REDCap-Randomization-Module.pdf)
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised into the three intervention arms in 1:1:1 ratio. Randomisation will be undertaken through the REDCap, with stratification balancing by age (45 years to less than 65, 65 years or more) and gender (man, woman, non-binary/gender diverse/prefer not to say).

Efficacy
Statistical methods / analysis
The statistical analysis plan is intended to be published separately. The primary analysis will use intention to treat analysis and a secondary per-protocol analysis will also be performed. The two intervention arms will each be compared to the one minimal active control arm. A direct comparison between the text message intervention and the online course intervention is not intended, as both will be available concurrently in real-world settings.
