Interventional
Description of intervention(s) / exposure
The 12-week group-based online-intervention (iSelf-help) will be delivered via an online smartphone application and a password-protected website.

iSelf-help: The iSelf-help has been co-designed with patients with persistent pain and Maori living with persistent pain and their whanau to ensure cultural appropriateness. The iSelf-help consists of 12 online modules similar to in-person pain management programme (PMP).

The 12 modules of iSelf-help are: 0) Welcome to Pain management programme, 1) Exercise, 2) Sensory nervous system, 3) Stress response, 4) Think, feel, do, 5) Memory of pain, 6) Taking charge, 7) Thinking and doing skills, 8) Medication, 9) Sleep, 10) Making plans with pain, 11) Sharing the journey, 12) Pulling it all together

Resources: Each module consists of a short introductory video (30s), educational video by a pain management clinician (5mins), videos of patient stories sharing their experiences of managing pain and associated symptoms relevant to the module, relaxation podcasts and additional resources such as animations, illustrated texts and links of additional resources.

Each module of iSelf-help will be made available to the participants at the beginning of each week. Participants are asked to use these resources at their own time.

In addition, the iSelf-help arm with 8 to 12 participants/group at baseline will receive two, 60-minute sessions weekly for 12 weeks.

One 60-minute session/week will be delivered via an online self-management platform by a dedicated pain management clinician (physiotherapist) of our research team. Each session comprises education (30mins), advice on guided exercises (15mins) and relaxation techniques (15mins). Education sessions are likely to focus on knowledge and Cognitive Behavioural Therapy-based self-management skills (e.g. pain education, activity pacing, relaxation, and distraction techniques) similar to in-person PMP. Participants are asked to attend the first session and any of the 5 sessions from the remaining 11 weeks.

Later in the same week, the second 60-minute session is likely to be an interactive online closed-group discussion moderated by a health coach (e.g. a trained volunteer from patient advisory group). The group discussion will focus on self-reflection, goal setting, and the sharing of experiences with peers about what went well, and what did not, over the week and developing peer support network. Participants are asked to attend these discussions at their own discretion.

Peer interaction: The community page of iSelf-help will provide opportunities for peer-interaction throughout the 12-week period. Acommunity manager (personnel with a health background) will monitor the page for safety of posts shared by participants.

Tracking: There will be opportunites for participants to track their exercise, mood level and thought diaries with reminders and nudges to encourage continued use of iSelf-help through the 12-week period.

Comparator / control treatment
Pain service site #1: The usual care arm with 8 to 12 patients/group at baseline will attend one 180-minute session/week over 12 weeks at Wellington, which is the current delivery model. Each session comprises weekly review (15 mins), two education sessions (45 mins each), group exercise (45 mins), relaxation (20 mins), and a debrief session (10 mins). Weekly education modules focus on a range of self-management strategies (e.g. pain education, CBT, activity scheduling) as delivered by pain management service clinicians.

Pain service site #2: All patients referred to pain management service in Christchurch will be invited to a Burwood Advancement, Screening and Education programme (BASE) educational seminar (7-hours in duration). BASE seminar involves chronic pain education and overview of self-management principles. On completing the BASE seminar and based on psychometric scores, patients are classified as having mild, moderate or high needs. Those classified with mild and moderate needs will be referred to attend the Burwood Pain Self-management Programme (BPSM). BPSM is an in-person delivered, 120-minute group-based session/week over 5 weeks. Each session comprises weekly review (15 mins), relaxation (15 mins), group exercises (40 mins), problem solving techniques for common difficulties associated with persistent pain such as sleep, flare-ups, communication, maintenance, and stress (30 mins) and a goal setting/trouble shooting session (30 mins).

As part of usual practice, the pain management service clinicians in both sites continually reflect after every in-person PMP session and following every cohort and take feedback from patients to adapt and improve their in-person delivery.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
To ensure concealed allocation, a research team member will hold the randomisation sequence in sequentially numbered opaque sealed envelopes and will provide envelopes sequentially to the research assistant (outcome assessor) at the end of baseline assessment. Thus, the research assistant will be blinded to the allocation sequence, and the Assistant Research Fellow will ensure the envelopes are opened in the correct order.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will then be block randomised (1:1) in to iSelf-help (intervention) and in-person (usual care) PMP groups with stratification by ethnicity (Maori or non-Maori) to ensure that both arms are similar in terms of ethnicity. The randomisation program (randomizer.org) will be used to generate a randomisation sequence in advance by our research team member not involved in recruitment, assessment or statistical analysis.

Sample size estimation
Trial sample size was calculated based on providing 80% power to detect non-inferiority using a 95% one-sided confidence interval. The margin for non-inferiority was a 3 points difference in changes (the minimal clinically important change) on the RMDQ scale and assuming no actual difference in changes between the two groups (iSelf-help and in-person PMP). The standard deviation for changes in RMDQ was calculated from data reported in a previous trial[51] of 471 participants with 397 excluding the wait-list control group. The standard deviation at baseline for RMDQ was approximately 5.0 (4.8–5.2 over the 4 groups), slightly higher at 3 months being around 5.7 (5.4–5.9 over the 3 groups with follow-up), and with correlations over 3 months of around r=0.5 (estimated from reported data to be 0.44–0.57 over the 3 groups with follow-up), giving an estimated standard deviation for changes of 5.4, which we have used for the six month changes here given the conservative rounding at each stage of the calculations. Allowing for a mean of 10 participants per group at baseline and a loss of 20% over the six months, i.e. a mean of 8 participants per group at follow-up, with an ICC of 0.1 for RMDQ changes, design effects at follow-up are conservatively estimated to be 1.7. A total of n=70 participants would be needed in each group at six months follow-up. To allow for the approximately 20% loss to follow-up, n=90 (across 9 groups) will be recruited into each arm of the study at baseline (n=180), that is 18 groups of 10 in total.

Statistical analyses
Baseline demographic and clinical characteristics will be described for participants in both groups. Linear mixed models will be used to model continuous outcomes (including RMDQ scores) collected over time (baseline, 12 weeks, 3 months, and 6 months) with random effects for participants and groups to accommodate the clustered data. No additional clustering for the two centres will be incorporated in analyses. For each model, an unstructured covariance matrix (and possibly other plausible structures if these are justified by theoretical considerations) for the longitudinal data will be investigated as an alternative to compound symmetry with positive correlations, with selection based on Bayesian Information Criterion values. Marginal and conditional residuals will be investigated to ensure model assumptions are sufficiently well satisfied and natural logarithmic transformations of dependent variables investigated to see if this improves meeting these assumptions. If model assumptions cannot be sufficiently well satisfied through such transformations, quantile mixed models will be used for analyses instead, modelling medians. For count outcomes (including health care use), Poisson or, if there is overdispersion, negative binomial mixed models will be used. Zero-inflated models will be considered if there is an excess of zero values. All models will include the stratification variable (Maori ethnicity). For any missing data, multiple imputation through chained equations and using forms of regression appropriate to the missing variables will be used for the main analyses (with additional analyses based on available data used to investigate the robustness of findings). Pattern-mixture models will be used to explore plausible scenarios of informative missingness. The primary analysis will be guided by intention-to-treat principles to address the effectiveness question, but a secondary analysis will investigate the per protocol efficacy question for those attending at least 70% of their sessions. Success for the intervention will be demonstrated by non-inferiority in changes of RMDQ at 6 months for the effectiveness question. Statistical analyses will be conducted using R 4.0.2 (or later) with two-sided p<0.05 used for statistical significance and one-sided 95% confidence intervals used for non-inferiority.
