A Pilot and Feasibility Trial of a Group Mindfulness and Self-compassion Intervention for Young People Diagnosed With IBD

A Pilot and Feasibility Trial of a Group Mindfulness and Self-compassion Intervention for Young People Diagnosed With Inflammatory Bowel Disease

Young people with IBD face all the usual complexities of growing up, with the additional complications of having a chronic health condition, often recently diagnosed, which can have a detrimental impact on their mental health.

This research seeks to examine the potential effectiveness of a two-stage intervention for young people with IBD via a pilot feasibility trial. First, a mindfulness-based stress reduction (MBSR) group with a "Mindfulness based compassionate living" (MBCL) group delivered soon afterwards. Both interventions will be delivered online. MBSR aims to increase peoples awareness of their tendency to get caught up in thoughts and help them live in the present moment. Once an individual has achieved greater awareness of their thought processes, MBCL then aims to help individuals to become kinder to themselves, and less critical. We know from interview studies with young people with IBD that they can be harsh on themselves about how they are coping, and being harsh and critical can impact wellbeing. By targeting mindfulness and self-compassion we hope to demonstrate a positive impact on wellbeing, by reducing stress, anxiety and depression and improving quality of life (primary outcome measures) for young people with IBD and equip them with a mindfulness practice to use in the future as they continue to manage their IBD.

Design: This study is designed as a pilot and feasibility trial, using a step-wedged design, and designed in line with CONSORT guidance. Pilot trials are used in advance of a larger future definitive randomised controlled trial (RCT) to focus on the development and refinement of the intervention, assess potential effectiveness, intervention acceptability and to determine whether a larger RCT is feasible. In step-wedged designs, all participants begin the study as 'control participants' and at regular 'steps' one group crosses from the control to the intervention condition, until all groups have completed the intervention. The step-wedged design is a pragmatic and financially viable design which reconciles the need for robust evaluations and logistical time constraints, as each participant acts as their own control. On conclusion of group participation, all participants will be invited to take part in one-to-one interviews with the lead researcher to discuss their experiences of MBSR+MBCL, to assess the acceptability of the intervention and inform future adaptations prior to larger trial.

Recruitment: Eligible and consenting participants will be identified in two ways. Firstly, by clinical staff at either Sheffield Teaching Hospital (NHS) or Sheffield Children's Hospital specialist IBD gastroenterology services and secondly, by poster, email or social media advertisements at the University of Sheffield and through relevant charitable organisations. Participants will be recruited on an ongoing basis and allocated to the next available group, or another, if the dates of the next group are not convenient.

Procedure: All consenting and eligible participants will meet with the lead researcher who will induct them into the trial and inform them of group allocation, and when they will commence the intervention. As in most psychological intervention trials, it will be impossible to blind participants to the interventions they are receiving. All outcome measures will be completed online via the Qualtrics platform.

Interventions (delivered online via video call): MBSR is an 8-week intervention consisting of 2.5 hour weekly sessions which involves the teaching and practice of formal mindfulness exercises, aimed at promoting the use of mindfulness in daily life for individuals experiencing stress, pain and/or illness. Participants are asked to engage in homework exercises which are intended to reinforce the techniques learnt each week. The intervention will aim to establish home practice and introduce self-compassion. MBCL is designed to be a follow-up intervention to a MBI. MBCL is a group intervention, also eight weeks in length and the sessions last 2.5 hours. The sessions contain a mixture of mindfulness practice, group discussion and didactic and interactive teaching. However, the content of the practices are different to traditional MBSR, focusing on turning towards suffering and developing a kind attitude to the self. Both MBSR and MBCL interventions will be taught by one of two accredited mindfulness teachers who have extensive experience in teaching MBIs, and who will complete the MBCL teaching training prior to the trial commencing. Adherence to the interventions will be measured by attendance at the group sessions and by participants home practice diaries. Fidelity to the interventions will be evaluated in line with guidance from previous studies and the application of a fidelity checklist.

Control condition: Prior to entering the intervention phase of the study, all individuals will begin in the control condition which consists of the routine medical monitoring and psychosocial support provided by gastroenterologists and IBD nurse specialists. Participants will be requested not to change their medication during the study, if at all possible, and to refrain from beginning any other psychological interventions.

Sample size: MBIs group sizes vary between 8 and 15 participants. Four groups will be conducted during the life of the grant, recruiting up to 60 participants. Despite being a pilot study we aim to achieve a sufficient sample size to adequately determine effectiveness. In line with previous studies of MBSR in chronic health conditions, assuming a conservative estimated medium effect size of d = .6 for our primary outcomes (e.g. depression and anxiety in diabetes) and a significance level of alpha = .05 (two-tailed), data from 45 participants would achieve 80% power45 and provide robust data for analysis.

Quantitative analysis: Statistical analysis will be carried out according to the principles of intention to treat. Repeated measures ANCOVAs will be conducted across all outcome measures, controlling for baseline measurements, to assess the potential impact of the intervention. Cohen's d effect sizes will be calculated to assess the magnitude of any potential change. In addition to the effectiveness of MBSR, and subsequently MBSR+MBCL, additional analyses to explore moderators of the treatment effects, such as disease type, age of diagnosis, current medication will be conducted. Sustainability of effects will be analysed via 3 and 6 month follow up data. The feasibility of the intervention will be evaluated via quantitative data on recruitment, enrolment, retention, attrition, missing data and fidelity to the model. Guidance on pilot and feasibility will be fully adhered to in reporting.

Qualitative Analysis: To assess the acceptability of the intervention, ascertain its value to participants and seek service-user views on any adaptations that would need to be made prior to a larger evaluation of the intervention, one-to-one interviews will be conducted with a sample of participants across the groups (aiming for a minimum of 12 participant interviews). All participants will be invited to take part, at the end of their respective group. The one-to-one interviews will be conducted by the lead researcher and be guided by an interview-schedule, designed to explore participants experience of the intervention in an open non-directive manner. Data will be transcribed and will be analysed using thematic analysis, which focuses on eliciting themes from participants' description of their experiences. Thematic analysis has been chosen as the methodology is not tied to a particular theoretical position, but offers a systematic approach to discerning themes in participant's accounts of their experiences.

Quality assurance plan: All aspects of the safety, monitoring and quality control of the data will be monitored by the a representative from the sponsor, there will be no separate Data Safety and Monitoring Board involved.
