Abstract
Objectives The Scleroderma Patient-centered Intervention Network—Scleroderma Support group Leader EDucation (SPIN-SSLED) Programme was designed to improve confidence and self-efficacy and to reduce burden for support group leaders. Objectives were to (1) evaluate feasibility of programme delivery, including required resources, management issues and scientific aspects (eg, performance of outcome measures) and (2) assess user satisfaction and identify any modifications needed to improve programme content or delivery based on participant feedback.
Design Non-randomised feasibility trial.
Setting North American patient organisations.
Participants Current support group leaders or potential new leaders referred by patient organisations.
Intervention The programme included 13 modules delivered live via videoconference over 3 months (April to July 2018) in 60 to 90 min sessions.
Outcome measures (1) Elements of feasibility, including enrolment and consent procedures, percentage of referred group leaders who consented to participate, session attendance and technical support requirements; (2) programme usability, understandability, organisation and clarity; (3) leader satisfaction with the programme and (4) planned trial outcome measures, including support group leader self-efficacy, burnout, emotional distress and physical function.
Results All 12 referred potential participants consented to enrol, and 10 were included in two training groups of five participants each. Participants attended 95% of sessions. Required technical support was minimal, and videoconferencing technology functioned well. Overall programme satisfaction rating was 9.4/10. Mean item rating on the eight items of the Client Satisfaction Questionnaire-8 was 3.83 (1=low satisfaction; 4=high satisfaction). Pre-post scores on the Scleroderma Support Group Leader Self-efficacy Scale increased by 1.7 SDs (large effect); scores on burnout, emotional distress and physical function improved by 0.44, 0.38 and 0.45 SDs (moderate effects).
Conclusion The SPIN-SSLED Programme was feasibly delivered, including management, resource and scientific aspects. Participant satisfaction was high. The programme is ready to be tested in a full-scale randomised controlled trial.

Strengths and limitations of this study
This is the first trial to test the feasibility of delivering an education and training programme via videoconference to peer support group leaders.
The education and training programme was developed in a partnership that included scleroderma peer support group leaders, patient organisation leaders and researchers and healthcare professionals.
Trial outcomes included elements of feasibility (eg, management, resources, scientific aspects); programme usability, understandability, organisation and clarity; leader satisfaction with the programme; and planned trial outcome measures.
This was a non-randomised feasibility trial that only included 10 participants in two training groups and did not include a control group; generalisability of results outside of scleroderma is not known.
Introduction
People with rare diseases face the same challenges as those with more common diseases plus unique challenges, including limited disease education and lack of specialised support options.1–12 Professionally organised support services for common diseases are often available through the healthcare system,13 14 but are not typically available for rare diseases.10 15 As a result, some people with rare diseases rely on peer-led support groups for disease-specific education and support.16–20 Support group activities typically involve an educational or information-sharing component and the exchange of emotional and practical support.14 18–22
Systemic sclerosis (SSc), or scleroderma, is a rare chronic, autoimmune connective tissue disease characterised by abnormal fibrotic processes and excessive collagen production.23–25 Support groups, most led by people with SSc, play an important role for many people with the disease.17 26–30 Many people with SSc, however, cannot access support groups because they are not available close to where they live, and many initiated support groups are not sustained due to challenges that could be addressed via leader training.18 19
A systematic review of randomised controlled trials (RCTs) that evaluated the effects of training programme for patient leaders of illness-based support groups on the competency, self-efficacy, burden and emotional well-being of group leaders identified only one RCT that met inclusion criteria.31 That trial32 evaluated confidence and self-efficacy of cancer support group leaders randomised to either 4-month long high-resource (n=29; website, discussion forum, 2-day face-to-face training) or low-resource (n=23; website, discussion forum) interventions. The RCT did not find evidence that the high-resource programme was more effective. However, the trial was substantially underpowered, not enough information was provided to determine intervention content or how it was delivered, and the risk of bias was high due to methodological limitations.
The Scleroderma Patient-centered Intervention Network (SPIN) partnered with SSc patients and patient organisations to develop the Scleroderma Support group Leader EDucation (SPIN-SSLED) Programme. The programme is a 13-session group videoconference training programme designed to improve skills and self-efficacy, reduce burnout and improve emotional and physical function among support group leaders. The objectives of the SPIN-SSLED feasibility trial were to (1) evaluate the feasibility of steps needed to take place in a planned full-scale trial, including the required resources (eg, staffing, time and budget), management issues (eg, related to optimising performance of personnel and data systems) and scientific aspects (eg, recruitment rates of eligible leaders, acceptability of intervention to leaders, assessing performance of outcome measures) and (2) identify any modifications needed to improve the content or delivery of the SPIN-SSLED Programme based on participant feedback.
Methods
The SPIN-SSLED feasibility trial was a non-randomised study. It was registered prior to enrolling participants (NCT03508661) and, although not a randomised study, is reported based on items from the Consolidated Standards of Reporting Trials (CONSORT) extension for randomised pilot and feasibility trials.33 There were no changes to the feasibility trial protocol and no changes to planned outcomes after commencement of the trial.
Participants
Eligible participants for the SPIN-SSLED feasibility trial were current SSc support group leaders or were identified by Scleroderma Canada or the Scleroderma Foundation (USA) as a new leader who will initiate a new support group, were able to use the internet to access and participate in training sessions and to complete study questionnaires online, were available to participate at times when sessions were scheduled and were English-speaking, since both groups in the feasibility trial were conducted in English. The full-scale trial will include groups conducted in French, but individuals who participated in the feasibility study will be excluded from the full-scale RCT. Thus, to ensure that there will be an adequate number of French-speaking participants in the full-scale RCT, only English-speaking leaders were included in the feasibility study.
Procedures
For the purpose of testing the feasibility of administering the SPIN-SSLED Programme, we sought 10 group leaders to participate in two separate training groups of five participants each. We asked Scleroderma Canada and the Scleroderma Foundation to generate an initial list of 12 interested potential participants and obtained permission for the SPIN team to send them an email with an invitation to participate in the feasibility trial and a copy of the consent form. Following the initial email, SPIN personnel contacted potential participants by phone within 48 hours to describe the study, assess their eligibility, review the consent form and answer questions they may have had about the study. Eligible leaders who verbally agreed to enrol in the study received a second email with the consent form again attached, and they were able to consent via email by replying, ‘I have read the consent form and understand the terms of the feasibility study. I agree to participate in the study testing the feasibility of the SPIN-SSLED Program.’ The first 10 people to respond and consent were enrolled, and the other 2 were put on a waiting list. All leaders who consented to participate and enrolled received an email invitation including a clickable link to the online data management platform where they were asked to complete baseline study measures. The email also included the date of their first training session, the topic of the first session and information on how to login to the videoconferencing system, as well as a link to the SPIN-SSLED online forum platform, where the programme manual and associated PowerPoint slides were available. Ongoing email and phone technical support was available to help leaders with the consent process, access to the data management platform to complete study measures and training sessions.
Intervention
The SPIN-SSLED Programme was developed by a team of researchers and healthcare professionals with expertise in SSc, patient organisation representatives and a Support Group Advisory Team comprised of people with SSc who are current SSc support group leaders. The programme content and design were based on results of our preliminary research on support groups in SSc, including individual interviews and surveys with leaders, members and non-attenders,17–20 and informed by instructional material for support group leaders in other diseases that we identified via the internet and by consultations with support group leaders. The programme uses a problem-based learning approach. Problem-based learning is a learner-centred approach that integrates theory and practice by providing the necessary knowledge and skills, presenting a complex, real-world problem, then working to identify an approach to solving the problem.34–37 To implement this, each module introduces a topic and provides an overview of key information. Then, there is a guided discussion among training group participants about possible approaches and solutions to problems.
The SPIN-SSLED Programme included 13 modules that are delivered live via videoconference over the course of 3 months. Each module is delivered in a 60 to 90 min session. Module topics include (1) the leader’s role; (2) starting a support group; (3) structuring a support group meeting; (4) scleroderma 101; (5) successful support group culture; (6) managing support group dynamics I; (7) managing support group dynamics II; (8) grief and crisis in scleroderma; (9) marketing and recruitment; (10) the continuity of the group; (11) supporting yourself as a leader; (12) virtual support group meetings and (13) support group leader resources (see table 1 for module content). The programme includes 11 filmed vignettes that demonstrate effective group facilitation techniques and ways to respond to problems that arise with the behaviours of specific group members or group interactions. In addition to the live modules, SPIN-SSLED participants receive a programme manual that summarises didactic material that is provided in the sessions.
Content of programme modules
Based on our previous experience with videoconferencing and consistent with previous trials of videoconference training, five group leaders were assigned to each training group to maximise effective interaction and participation.38–41 Training sessions were delivered using the GoToMeeting videoconferencing platform, a high-performance platform that has been used successfully for similar applications.42–44 In addition to the videoconference sessions, participants had access to a secure, monitored SPIN-SSLED online forum via the Slack communication tool to interact with other participants about programme content. The two training groups were held in the evening.
Feasibility outcomes
Outcomes related to process and resources were assessed throughout the duration of the feasibility trial, and leader feedback was obtained on completion of the programme. The collected measures of feasibility included assessments of the (1) enrolment and consent procedure, (2) percentage of referred and eligible group leaders who consented to participate, (3) personnel requirements to assist participants with accessing the GoToMeeting videoconferencing platform for sessions and the online survey programme Qualtrics for online data collection pre-training and post-training, (4) technological performance of the videoconferencing system and (5) any challenges for study personnel.
Individual semistructured interviews were conducted with all participants via telephone on completion of the 13 modules using items based on the Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT)45 and addressed topics related to usability, understandability, organisation and clarity of the SPIN-SSLED Programme, including its videoconference-based delivery. The PEMAT included a single rating of satisfaction from 0 (worst possible) to 10 (best possible).
SPIN-SSLED planned trial outcome measures
In the planned full-scale RCT, we will evaluate whether the SPIN-SSLED Programme is effective in improving SSc support group leaders’ self-efficacy for carrying out their leader role (primary) and if the programme reduces burnout, improves emotional well-being and improves physical function among support group leaders (secondary). The SPIN-SSLED feasibility trial was not intended to test hypotheses and did not have adequate power for this, but we collected trial outcome measures at the time of consent to participate in the trial and following completion of the programme to evaluate the percentage of measures that were completed and to evaluate performance of the measures. Participants were emailed invitations to complete baseline and postintervention measures using the online survey programme Qualtrics.
Leader self-efficacy
The Scleroderma Support Group Leader Self-efficacy Scale (SSGLSS)46 was developed by our research team, including the members of the SPIN Support Group Advisory Team, to measure support group leader self-efficacy for performing leader tasks. Initial items were obtained from the Group Leader Self-Efficacy Instrument, a 37-item self-report questionnaire that assesses self-efficacy for performing group leader skills.47 The Group Leader Self-Efficacy Instrument is intended for use with group psychotherapy leaders, so many of its items are not relevant or appropriate for support group leaders. Items from this instrument were reviewed for relevancy, and relevant items were considered for inclusion, along with items from a questionnaire intended for leaders of cancer and multiple sclerosis support groups48 and items that we generated from the results of a published study on the experiences of leaders of cancer support groups.49 All items were then reviewed by members of our research team to remove items that were repetitive or not relevant for SSc and to generate new items to reflect important SSc-specific content based on their own experiences or on qualitative interviews that we conducted with SSc support group leaders (n=10). Items were then reviewed iteratively by all members of the research team until a consensus was reached on included items. The resulting 32-item scale is scored on a 6-point Likert scale from 1 (strongly disagree) to 6 (strongly agree) with possible total scores from 32 to 192 and higher scores indicating greater self-efficacy. The SSGLSS was validated in two samples of SSc support group leaders (n=102, n=55) and found to have good internal consistency (Cronbach’s alpha 0.96 and 0.95) and hypothesis-consistent convergent validity with the Oldenburg Burnout Inventory (OLBI). A strength of using the SSGLSS as the primary outcome measure is that both the intervention and the SSGLSS were designed to reflect training needs of SSc support group leaders, and the items of the SSGLSS all reflect material covered in the programme.
Burnout
Leader burnout was assessed with the OLBI,50–52 which is a 16-item measure that assesses exhaustion and disengagement due to burnout. The OLBI was initially designed for work-related burnout, but has been adapted for numerous settings and in multiple countries and languages.52 Our research team revised the wording of each OLBI item to reflect the support group environment rather than a work environment (eg, ‘I find my work to be a positive challenge’ was revised to ‘I find my role as a support group leader to be a positive challenge’). The OLBI has a two-factor structure (exhaustion and disengagement) with good measurement properties.50–52 Items are scored on a 4-point scale; higher scores indicate higher levels of exhaustion and disengagement. Internal consistency reliability (Cronbach’s alpha) in patients with SSc was 0.84 for exhaustion and 0.80 for disengagement.46
Emotional distress
The Patient Health Questionnaire-8 (PHQ-8) was used to assess emotional distress.53 The PHQ-8 items measure depressive symptoms over the last 2 weeks on a 4-point scale, ranging from 0 (not at all) to 3 (nearly every day) with higher scores indicating more depressive symptoms. The PHQ-8 performs equivalently to the PHQ-9,53 which has been shown to be a valid measure of depressive symptoms in patients with SSc.54
Physical function
Physical function was measured using the Physical Function subscale of the 29-item Patient-Reported Outcomes Measurement Information System (PROMIS-29) V.2.0. The PROMIS-29 measures eight domains of health status with four items for each of seven domains (physical function, anxiety, depression, fatigue, sleep disturbance, social roles and activities, pain interference) plus a single item for pain intensity. Items are scored on a 5-point scale (range 1–5), with different response options for different domains, and the single pain intensity item is measured on an 11-point rating scale. Higher scores represent more of the domain being measured; that is, better physical function. Total raw scores are obtained by summing item scores for each domain. The PROMIS-29 V.2.0 has been validated in SSc.55
Participant satisfaction
Satisfaction with the SPIN-SSLED Programme was evaluated with the Client Satisfaction Questionnaire-8 (CSQ-8),56 a standardised survey that is used to assess satisfaction with health services. Items are scored on a Likert scale from 1 (low satisfaction) to 4 (high satisfaction) with total scores ranging from 8 to 32. The CSQ-8 has been widely validated across a range of populations and health services programme.57
Adverse events
Following each session, we emailed participants and requested that they report any concerns that they had about the sessions or their experience in the sessions.
Sample size
Guidance on appropriate sample size for feasibility trials varies substantially in the published literature. For the purposes of establishing feasibility of delivery of the SPIN-SSLED Programme, we determined that conducting two different training groups would allow us to evaluate intervention content and delivery aspects, and, thus, we sought to recruit a total of 10 participants to conduct two training groups.
Data analysis
Feasibility outcomes included leader eligibility and recruitment, leader enrolment and technological performance of the videoconferencing system. Qualitative information via interviews and weekly reports by participants was collected, and all suggestions for changes to the programme or trial methods that could be implemented prior to beginning a full-scale trial were recorded. Descriptive statistics were used to provide means and SD for SPIN-SSLED Programme outcome measures. Since the purpose of this feasibility trial was to evaluate feasibility and identify any modifications to the intervention or trial plan, the trial was not designed or powered to test hypotheses about outcomes. Thus, consistent with best practices,33 hypothesis tests were not conducted, but effect sizes for pre-post differences are shown. Data were analysed using the statistics software programme, IBM SPSS.
Patient and public involvement
The SPIN Support Group Advisory Team has been involved in all stages of SPIN’s research on support groups in SSc, including preliminary research on support groups in SSc, the development of the SPIN-SSLED programme and the design and implementation of the feasibility trial. Members of the team initially participated in the design of the Scleroderma Support Group Survey, which informed developing of the programme by collecting information on the experiences and training needs of SSc support group leaders, priorities of SSc support group members and reasons why people do not attend SSc support groups.17–20 Team members participated in the development of the SSGLSS,46 which was administered in the feasibility trial and will be the primary outcome for the planned full-scale trial. Team members provided input into the development of the SPIN-SSLED Programme and its modules, filmed the vignettes used in the programme and were involved in decisions related to the conduct of the feasibility trial.
Results
Participant characteristics
The trial was conducted between April and July 2018. Scleroderma Canada and the Scleroderma Foundation each provided our team with names of six potential participants. All agreed to participate in the programme. We initially enrolled 10 participants, but one was hospitalised prior to initiating the programme. Thus, prior to starting the trial, we added one participant who had been wait-listed.
All 10 participants were female. The mean age was 58 years (SD=11 years). There were six participants from Canada and four from the USA. All 10 described themselves as White, and one also described herself as Aboriginal. Of the 10 participants, 9 were people with SSc. Mean years since diagnosis among those with SSc was 11 years. Participant characteristics are shown in table 2.
Participant characteristics
Feasibility outcomes
All 10 participants completed all baseline and post-trial measures, including the PEMAT interview. Participant attendance at the weekly sessions was high (95%; 123 of 130 sessions). No sessions were missed or delayed due to technological difficulties, and time for technological support from our team was between 1 and 2 hours for the entire programme. Per the PEMAT interviews and per our observations, the GoToMeeting system worked fluidly and supported the training groups well.
A summary of responses to the PEMAT interviews is shown in table 3. As can be seen in the table, there were relatively minor suggestions for improving the programme. Overall, feedback was extremely positive. The overall mean grade given by participants for the SPIN-SSLED Programme was 9.4/10. No concerns related to adverse events were reported.

SPIN-SSLED planned trial outcome measures
Table 4 shows the responses to each of the 32 items of the SSGLSS, which will be the primary outcome measure in the full-scale trial. Pre-training, the mean (SD) was 124.4 (22.0), which was similar to the scores of our two international samples from the SSGLSS validation study (n=102, mean SSGLSS=122.9 (21.7); n=55, mean SSGLSS=123.9 (19.4)). Post-training, the mean total score increased to 159.2 (17.1). The standardised mean difference effect size was 1.70, which is considered a large effect size.58 SSGLSS items are scored on a 1–6 scale, and the average item score increase pre-post training was 1.1 points.
Pre-intervention and post-intervention item and total scores for the Scleroderma Support Group Leader Self-efficacy Scale: possible item scores range from 1 to 6 with higher scores reflecting greater self-efficacy
Table 5 shows results for health outcomes, including burnout (OLBI), emotional distress (PHQ-8) and physical function (PROMIS-29). For all of these outcomes, the standardised mean difference effect size of post-trial score improvement was between 0.38 and 0.45, which are typically considered small to moderate effect sizes.58
Pre-intervention and post-intervention total scores for secondary outcome measures
As shown in table 6, the mean post-training score on the CSQ-8 was 30.6 (2.2). On a per item basis, the mean item score (possible range 1–4) was 3.8, reflecting a very high level of satisfaction with the experience of trainees with the SPIN-SSLED Programme.
Post-intervention items, frequencies and total scores for the Client Satisfaction Questionnaire-8: item response options vary across items, but all scored 1–4
Discussion
Feasibility of delivering the SPIN-SSLED Programme in the context of a trial, participant satisfaction and programme content was evaluated in the SPIN-SSLED feasibility trial. Results informed revisions to the content of the programme and provided confidence that the programme can be effectively and efficiently delivered in a full-scale trial.
With respect to overall experience with the programme and programme content, participants reported that the content was clear and well-organised. Overall satisfaction with their experience in the SPIN-SSLED Programme was rated as 9.4 out of 10 on average. Participant satisfaction was similarly high when evaluated with the eight items of the CSQ. Several participants encouraged the research team to expand on the single module related to grief. Based on comments and follow-up discussions with participants, the programme was revised to include two modules on grief, including one module on grief and loss that leaders have experienced because they or somebody close to them has been diagnosed with SSc and a second module on providing support to group members who are struggling with grief and loss. In order to add a second module on grief and loss, the two modules on managing group dynamics were reduced to a single module. To facilitate this, rather than viewing all of the short video vignettes included in those modules as part of the training sessions, participants suggested that they could view the vignettes prior to the sessions and then suggest specific modules for review and discussion in the training sessions.
With respect to programme delivery, participants indicated that they were able to access the sessions via the GoToMeeting platform and did not experience any technical difficulties that interrupted their training sessions. One difficulty that was reported involved a participant with a hearing impairment who was unable to hear all of the vignette videos well. This information will help us to assess for reasons why participants may need additional support in the full-scale trial and will allow us to make accommodations. In the full-scale trial, we will assess for hearing and any other impairments that might limit participation, and we will seek appropriate assistance to be able to provide adaptations to meet participant needs. From a management standpoint, total time for technical support due to access difficulties across the trial period for the two groups was between 1 and 2 hours. Participants attended 95% of sessions, and all 10 participants completed all baseline and post-trial outcome assessments.
There were limitations that should be considered in evaluating the results of the SPIN-SSLED feasibility trial. First, we were provided with a small list of potential participants from our patient organisation partners, and it is possible that these support group leaders were more motivated or otherwise more likely to participate and engage than the leaders who will participate in the full-scale trial. Second, we did not randomise participants to the intervention and to a wait-list control group as we will do in the planned full-scale trial. Third, we only conducted two training groups and only included a total of 10 participants. The reason for not using a control group and limiting the feasibility trial to two groups is that there is a finite number of English-speaking and French-speaking SSc support group leaders, and we wanted to be able to assess feasibility aspects but maximise the number of participants eligible for the full-scale trial. It is possible that the pre-selection of potential participants and the lack of the possibility of randomised assignment to a non-intervention group may have resulted in overestimation of the percentage of participants who will enrol in the full-scale trial and the degree to which they will actively participate. Given the small number of French-speaking leaders available for the full-scale trial, we did not include a French group in the feasibility trial. However, all measures have been used successfully previously with French-speaking research participants. Finally, the trial only included leaders of SSc support groups, and this may limit generalisability to other patient populations, but it will be useful to inform our planned full-scale trial of the SPIN-SSLED Programme.
There are no existing training programme for SSc support group leaders, and a systematic review did not identify any training or education programme that have been demonstrated to be effective for support group leaders in any medical condition.31 The planned full-scale SPIN-SSLED trial, which was recently funded by the Canadian Institutes of Health Research, is scheduled to begin in 2019 (http://webapps.cihr-irsc.gc.ca/decisions/p/project_details.html?applId=388187&lang=en). It will be a pragmatic RCT that will test whether providing the SPIN-SSLED Programme to leaders of SSc support groups will improve outcomes compared with leaders assigned to a wait-list control. Pragmatic RCTs differ from explanatory or mechanistic trials, in that they are intended to test the effectiveness of adding an intervention to routine practice in order to inform practice and policy decisions rather than explain intervention mechanisms.59 60 SSc support group leaders who are enrolled will be randomly allocated to the training programme or a wait-list control, and those allocated to training will be clustered in training groups where they will interact with each other. To account for clustering in the training arm, but not the control arm, we will use a partially nested RCT (PN-RCT) trial design.61–63 The PN-RCT design is a hybrid between a conventional RCT, in which individual participants are randomised, and a cluster RCT, in which pre-existing clusters (eg, primary care practices, classrooms) are randomised to intervention or control arms. In the PN-RCT design, analyses account for dependence within intervention arm clusters, but treat leaders assigned to the control arm individually, as in a conventional RCT. Participants will be existing support group leaders or new leaders referred by Scleroderma Canada (English) or Sclérodermie Québec (French), the Scleroderma Foundation (USA), Scleroderma and Raynaud’s UK, the Scleroderma Association of New South Wales (Australia) and Scleroderma New Zealand.
In sum, the SPIN-SSLED feasibility trial ensured that trial methodology was feasibly implemented and that the online intervention was user-friendly and acceptable to participants. Participants provided suggestions for adjustments to content that will be implemented before undertaking a full-scale RCT of the SPIN-SSLED programme to assess effectiveness.
