Description of intervention(s) / exposure
Intervention Group: Proactive engagement group
Survivor-support person dyads allocated to proactive engagement group will receive the materials including: Stroke Foundation’s “My Stroke Journey workbook”, a follow-up phone call from the Stoke Foundation from the Stroke Connect Service at 6 weeks post discharge from hospital and access to enableme web portal. The intervention group will receive access to the web portal online as required for the duration of the intervention period (6 months). The website includes information about stroke, treatments, forums for communications with others, and goal setting functions. Proactive strategies will be used throughout the intervention period to encourage use of the web portal. Proactive engagement strategies include: a letter from their stroke physicians, short message service (SMS) or email reminders to access the portal if usage is low, and letter which provides feedback regarding their use of the portal at 3 and 6 months.

Control Group: Usual care group
Survivor-support person dyads allocated to the usual care group will receive usual care plus the Stroke Foundations “My Stroke Journey workbook”. Usual care may include referral to rehabilitation services. education and provision about Stroke Foundation resources. The enableme portal is publicly available, access will not be restricted. However, participants in usual care group will not receive prompts regarding access.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following completion of the baseline measures and consent for the RCT the survivor will be randomised to either: (1) usual care or (2) intervention, stratified by recruitment site. The randomisation schedule will be delivered in real time via secure web-based interface upon entering of the baseline survey. The randomisation allocation will be generated by the computer driven algorithm and displayed on-screen to the research assistant.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Group allocation will be created dynamically with block sizes varying randomly. Allocation will be stratified based on treatment centre.
Masking / blinding
Open (masking not used)

Efficacy
Statistical methods / analysis
Age, type of stroke and stroke severity will be compared between consenters and non-consenters using a t-test (or a non-parametric equivalent) for continuous variables and the chi-square test (or fishers exact test) for categorical variables.
Characteristics of the stroke survivors and SPs will be compared between experimental groups using means, standard deviations, medians and interquartile intervals for continuous variables and by percentages for categorical variables.
Between-group differences in the proportion of depressed participants will be assessed at all post baseline study time points using separate logistic regressions for survivors and SPs.
Differences in quality of life at each post-randomisation period will be assessed using a linear regression model.
Multivariable linear mixed effects regression models will be used to identify whether use of Enable Me and/or patient demographic and diagnosis factors are associated with scores on the PHQ-9, or the SF-12.
Sample size: Using a conservative estimate (i.e. 70% of eligible survivor-patient dyads will consent), 850 dyads will be approached in order to recruit 600 dyads (300 dyads per group) at baseline. Allowing for 20% attrition by 3 months’ follow up and 30% by 6 months due to death, loss to follow up and study withdrawal, a sample of 240 per group at 3 month follow up, and 210 per group at 6 months follow up will be available. For depression, assuming a baseline prevalence of 30%, we will have 80% power to detect a prevalence difference of 10% at 3 months for survivors and less than 10% for SPs (assuming lower prevalence of depression in SPs) at the 2.5% significance level. For survivors and SPs we will have 80% power to detect differences between groups of 0.3 SD in QOL at 3 months and 0.33 SD at 6 months at a 2.5% significance level. Consent rates between 70% and 90% have been reported in previous studies in this population.
