Description of intervention(s) / exposure
This trial tests yoga and cognitive-behavioural therapy (CBT)

CBT for chronic pain: Participants randomized to CBT will attend 8 weekly group CBT sessions of 120 minutes (minimum 10, max 13 participants/group) either in person or online, delivered by provisional psychologists under the supervision of a senior psychologist. The program draws on Beverly Thorn’s widely available CBT protocol for pain. The program aims to assist individuals to: gain an understanding of pain including education about chronic pain; learn practical strategies for managing pain and mood; practice the techniques both in and outside of the group setting, and; and learn how to maintain the gains they have made during therapy and prevent relapse. Participants will be encouraged to complete 20 min home practice (at least 3 days/week) involving working through the techniques introduced during sessions led by the therapist. The task for each week will be distributed via email. Adherence to the intervention will be monitored with attendance checklists.

Yoga therapy: Participants randomized to yoga will attend 8 weekly group yoga sessions of 60 minutes (minimum 10, maximum 13 participants/group) either in person or online. Classes include: physical postures (suitable for all levels of experience, with adjustments for individual physical fitness and health issues); breath awareness and techniques; and relaxation and meditation.
The yoga sequence will be based on vinyasa yoga in the tradition of T. Krishnamacharya, which emphasizes adaptations for health conditions. Classes will be led by experienced yoga therapists. Adherence to the intervention will be monitored with attendance checklists. Before beginning classes, participants will attend a 60 minutes session with the yoga therapist to develop their home practice schedule, accounting for any injuries or health issues. Participants will be encouraged to complete 20 min home practice (at least 3 days/week)- involving simple movement and breathing techniques, with the aim of setting a new positive pattern for participants to continue after study completion. These sessions will be monitored for the duration of the intervention. Patient’s home practice fidelity and adherence will be measured with a logbook.

Comparator / control treatment
standard care + education

In addition to standard medical care (e.g. hormones, SSRIs, SNRIs and TCAs such as amitriptyline), the control group will receive standardised educational care, consisting of weekly educational handouts on endometriosis. This is consistent with endometriosis education patients receive from their treating physician. Eight weekly topics align with 8 topics: symptoms, diagnosis, management, fertility, emotions complications, relationships and endo stories. These materials will be delivered to participants via email. At 12 months, patients will be offered their choice of yoga or CBT. These participants will not be followed up after they start the intervention.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will involve contacting the holder of the allocation schedule (the study statistician) who is based at central administration site with no access to participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation schedule will be created using computer software by the study statistician who has no direct patient contact.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

The people analysing the results/data
Intervention assignment
Parallel
Other design features
Blinding the treatment groups is not possible as is often the case in psychotherapy and mind-body trials. However, outcome measures will be collected by a blinded researcher, and the investigators will be blinded to participant allocation, making it a single-blinded study.
Phase
Not Applicable
Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
The data will be analysed using mixed-effects ANOVA and linear models to identify change over time within and between groups, followed by post-hoc analyses to identify statistically significant differences. Analyses will be carried out on intention-to-treat basis. To reduce bias, the statistician analysing the data will be blind to group allocation during the data analysis.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
We believe participants (a chronically ill cohort) might be reluctant to participate if we decided to share their health-related data. Further, we are initiating a program of research in this area and want our team to be able to use the data in future publications. This is not a large dataset and thus by opening it to others we might lose the opportunity to publish the data ourselves.
