Many people living with a rare disease turn to peer-led support groups to cope with their condition and access educational resources. Systemic sclerosis (SSc), or scleroderma, is a rare autoimmune connective tissue disease where peer-led support groups play an important role. There are currently approximately 200 SSc support groups in Canada and the US, most of which are led by people with SSc. Many SSc patients, however, cannot access support groups. In other cases, support groups are not sustained due to factors that include the burden on group leaders living with a serious, unpredictable disease and limited group leadership skills of some untrained leaders. Our partners from Scleroderma Canada and the Scleroderma Foundation in the US are committed to improving support group accessibility and effectiveness. These organizations maintain a list of active support groups, but currently do not provide training or other resources to groups or their leaders. To address this gap, our team, including investigators and patients from the Scleroderma Patient-centered Intervention Network (SPIN), developed the Scleroderma Support group Leader EDucation (SPIN-SSLED) Program, which is designed to improve support group leader confidence and self-efficacy, reduce burnout, improve emotional well-being, and improve health-related quality of life.

In the planned full-scale randomized controlled trial (RCT) that will follow our feasibility trial, we will evaluate whether the SPIN-SSLED Program is effective in improving SSc support group leaders' self-efficacy for carrying out their leader role (primary) and if it reduces burnout, improves emotional well-being, and improves health-related quality of life (secondary). Thus, the SPIN-SSLED Feasibility Trial answers the following research questions: (1) Is a full-scale SPIN-SSLED RCT feasible? (2) Are adaptations needed to the research design for the planned full-scale RCT? (3) Are there ways to improve the SPIN-SSLED Program for delivery in the planned full-scale RCT based on input of support group leaders who participate in the feasibility trial?

People with rare diseases experience many of the same challenges as those with more common diseases, but also face unique challenges, including gaps in knowledge about their disease and limited treatment and support options. Professionally organized support services are often available for people with more common diseases but are not typically available for people with rare diseases. Instead, many people with rare diseases rely on peer-led support groups for education and to cope with their disease. Support groups may be held face-to-face or online, led by professionals or peers, and have a structured or an unstructured format. Activities typically involve an educational or information-sharing component and the exchange of emotional and practical support.

SSc is a rare, chronic, autoimmune connective tissue disease characterized by abnormal fibrotic processes and excessive collagen production. Peer-led support groups play an important role for people with the disease. There are currently approximately 200 active SSc support groups listed by Scleroderma Canada or the Scleroderma Foundation in the USA, most led by people with the disease. Many people with SSc, however, do not have access to SSc support groups, and many support groups that are initiated are not sustained due to obstacles that could be addressed by providing training to support group leaders. Challenges for patient support group leaders, particularly in rare diseases, include practical difficulties, such as a lack of resources or poor coordination with medical professionals and leader organizations; difficulties with group leadership tasks, such as managing complex group dynamics; and personal challenges, such as managing one's own health condition while supporting others and preventing burnout.

A training and education program could provide the necessary information and skills to improve the ability of SSc peer support group leaders to lead sustainable, effective support groups; reduce their emotional and physical burden; and encourage new leaders to set up support groups where none exist or via the internet. In rare diseases, face-to-face delivery of such a training program is not feasible because current and potential leaders are widely dispersed geographically. Videoconferencing has been used successfully to train educators, health service providers, and parents of children with behavioural difficulties, for example, and is as effective as face-to-face training.

The SPIN-SSLED Program was developed by a team of researchers with expertise in SSc, patient organization representatives, and a Patient Advisory Board comprised of current SSc support group leaders. The program content and design are based on results of our preliminary research on support groups in SSc and informed by instructional material for support group leaders we identified via the internet and by consultations with support group leaders. The program uses a problem-based learning approach. Problem-based learning is a learner-centered 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. To implement this, each module, or learning session, will introduce a topic and provide an overview of key information. Then, there will be a guided discussion among training group participants about possible approaches and solutions. The program includes 13 modules that will be delivered live via webinar over the course of the 3-month program. In addition to the live modules, SPIN-SSLED participants will receive a workbook that summarizes didactic material that is provided and will be shown filmed vignettes demonstrating effective group facilitation techniques and ways to respond to support group issues. SPIN-SSLED participants will also have access to an online resource center that includes a range of helpful tools for leaders including files of SSc related videos to show at meetings and an online forum for leaders to post questions, open only to leaders enrolled in the training program.

The proposed SPIN-SSLED Program Feasibility Trial builds on this background research and will evaluate the feasibility of delivering the SPIN-SSLED Program and of our planned full-scale trial design. The objectives of this study are (1) To evaluate the feasibility of steps needed to take place in the full-scale trial, including the required resources (e.g., staffing, time, and budget), management issues (e.g., related to optimizing performance of personnel and data systems), and scientific aspects (e.g., recruitment of eligible leaders, fidelity of intervention delivery, acceptability of intervention to leaders, assessing performance of outcome measures); (2) To make any necessary modifications to the SPIN-SSLED Program based on participant feedback

The aim of the SPIN-SSLED Feasibility Trial is to collect data related to the study's process, in order to assess the feasibility of the steps that need to take place as part of the main study; required resources (e.g., staffing, time, and budget), management issues (e.g., optimizing performance of personnel and data systems); and scientific aspects (e.g., recruitment rates of eligible leaders, fidelity of intervention delivery, acceptability of intervention to leaders, performance of outcome measures).

Our partners from the Scleroderma Canada and the Scleroderma Foundation will contact group leaders to describe the SPIN-SSLED Feasibility Trial and ascertain interest in participating. SPIN-SSLED personnel will send email invitations with the consent form to interested support group leaders. Following this, support group leaders will be contacted by phone within 48 hours to describe the study, review the consent form, and answer questions assessing eligibility. Eligible patients who verbally accept the offer to enrol in the study will receive an email with the consent form for the study, which they can sign 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." We will enroll 10 SSc support group leaders to participate in the program. Based on our previous experience with videoconferencing and consistent with previous trials of videoconference training, to maximize effective interaction and participation, 5 group leaders will be assigned to each training group. Training sessions will be delivered using the GoToMeeting® videoconferencing platform, a high-performance platform that has been used successfully for similar applications.

A survey will be administered to all participants before the trial. The survey will contain a demographics questionnaire designed for this study that includes basic demographic information, such as gender, age and employment status. The survey also includes disease-related variables, such as years since scleroderma diagnosis and questionnaires for all outcome measures. These questionnaires will be administered again upon completion of the program, along with a satisfaction questionnaire. All questionnaires will be completed using the online surveying tool Qualtrics. Once the online survey data is collected, data will be exported to the statistics software program, IBM SPSS.

A description of feasibility outcomes will be presented, including leader eligibility and recruitment, leader enrolment and randomization, technological performance of the videoconferencing system, and treatment fidelity. Qualitative information will inform any necessary changes to the program or trial methods before conducting a full-scale trial. Descriptive statistics will be used to provide means and standard deviations for SPIN-SSLED Program outcome measures.
