Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Prior to commencing in the trial, participants will have completed a six-week memory skills group program. The group program comprises one two-hour session each week (including breaks) in groups of 3-8 people who report memory difficulties after experiencing an acquired brain injury (ABI). Sessions are facilitated in-person by qualified clinicians. Program content includes psychoeducation regarding memory functioning, practical training in internal and external compensatory memory strategies, and information about relevant impacts to memory functioning from lifestyle factors such as diet, sleep, and exercise. Interactive in-session exercises and between-session homework tasks are included to encourage practice and application of trained skills and strategies in everyday contexts.

All memory skills group sessions will be video recorded throughout the study period, for treatment fidelity checks of a random selection of sessions by an independent expert. Treatment fidelity monitoring will include measures of adherence (using a session content checklist) and competence (using the eNACT Group Facilitation Competency Checklist).

At the conclusion of the memory group program, interested participants will be contacted by study staff to be formally enrolled in the Memory-SuSTAIN study and randomised into one of the following two study arms (or a control condition, consisting of usual care involving no active follow-up maintenance):

Arm 1: Telehealth booster sessions
Participants in the Booster Sessions condition will receive three fortnightly sessions of one-hour duration each, with a trained clinician. Sessions will comprise:
• Checking the progress of rehabilitation goals (previously negotiated with memory group clinicians);
• Reviewing and consolidating key compensatory and lifestyle strategies covered during the memory group program;
• Expanding the number and range of everyday situations to which these memory strategies could be applied; and
• Addressing any barriers to ongoing implementation of strategies.

Booster sessions will occur remotely via videoconferencing using Zoom, a freely available software program facilitating Internet-enabled videoconferencing. Booster sessions will also be video recorded and treatment fidelity checks conducted by an independent expert.

Arm 2: SMS/Email Reminders
Participants in the SMS/Email Reminder condition will receive one strategy message per week for six weeks, sent either to their mobile phone as a text message or to a nominated email address, depending on each participant’s preference. Reminder messages will prompt participants to use their three most relevant strategies learned during the memory group program.

Following group allocation, participants in the SMS/Email Reminders condition will be asked to nominate their three most useful personally salient strategies from a list of all strategies taught in the memory skills group. These strategies will inform the range of reminder prompts that they receive. Strategies will be identified from a list covering the following areas:

Internal Strategies:
o Using repetition to enhance encoding (mental rehearsal, asking others to repeat, re-reading text);
o Using association to enhance retrieval;
o Route-finding strategies: Paying attention to key features to enhance encoding;
o Using context to assist recall;
o Word-finding and conversations: focusing on meaning, using association, and descriptions;
o Learning and recalling names: using alphabet search, association, and elaboration;

External Strategies:
o Optimising the home environment: decreasing distractions, reducing clutter;
o Using note-taking, diaries, calendars, physical reminders, and alarms;
o Using smartphones and electronic devices;
o Using checklists for complex tasks.

Messages will be delivered using the iVERVE platform, an electronic automated messaging system designed and developed by Cadilhac et al. (2018) for message-based e-health interventions. iVERVE will store a bank of strategy reminder messages and securely extract de-identified participant data (selected strategies matched with each relevant participant’s nominated phone number or email address) from a secure web-based database management system (REDCap; Harris et al., 2009). Study data will be collected and managed using REDCap (Research Electronic Data Capture) electronic data capture tools hosted and managed by Helix (Monash University; Harris et al., 2009). REDCap is a secure, web-based application designed to support data capture for research studies, providing 1) an intuitive interface for validated data entry; 2) audit trails for tracking data manipulation and export procedures; 3) automated export procedures for seamless data downloads to common statistical packages; and 4) procedures for importing data from external sources. Automated messages will be sent to participants at designated times, once per week for six weeks.

All participants will have completed the memory group program. Following completion of the program, participants will be randomised into one of three conditions: two different intervention conditions and a No Active Maintenance condition. Commencing at six weeks after completion of the memory program, the intervention conditions will start for participants randomised into those conditions. and run for a six-week period. During this phase, participants in the No Active Maintenance condition will not be contacted by study staff for any follow-up or maintenance purpose, with the exception of a reminder message for the next follow-up outcome assessment.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Group allocation will take place within REDCap (a secure, web-based application designed to support data capture for research projects, including a randomisation module). The randomisation schedule is first generated using Stata, before being uploaded to REDCap using the randomisation module, which is designed to ensure allocation concealment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be generated by the Research Officer using Stata Version 15 (StataCorp, 2017). The sequence will be generated using random block sizes with 6 allocations per block (2 per condition), stratified by health service site to ensure equal distribution across sites.

Summary
Brief summary
Addressing memory problems after stroke is a research priority due to significant unmet needs reported by survivors of stroke. Memory rehabilitation, including group programs based on teaching people strategies to compensate for their memory problems (such as using diaries or calendars), has been shown to produce significant short-term improvements in memory after a stroke. However, difficulties establishing new strategies into everyday routines can mean that effects are inconsistently maintained over time.

In this project, we seek to evaluate the following two eHealth maintenance intervention programs that are designed to sustain the improvements in everyday memory made following six weeks of group-based memory skills training:
1) Booster sessions delivered via telehealth (videoconferencing), and
2) SMS or email reminders prompting use of memory strategies taught.
As well as evaluating whether these eHealth interventions are effective in maintaining the use of strategies that enhance memory function, we are seeking to assess whether these interventions are appropriate, practical, and potentially cost-effective. In order to evaluate whether these intervention strategies are effective in helping people maintain their benefits, we will compare the results that we find from the two treatment options against results from having no maintenance support (which is the current practice).

Identifying effective strategies for maintaining the benefits of memory rehabilitation could help reduce the long-term impact of these problems after a stroke. These benefits could include increased independence and employment opportunities, as well as better quality of life for those recovering from a stroke and their families.
