Description of intervention(s) / exposure
CodeEndo is a online modular self-directed supportive care program for people living with endometriosis.

Phase 1: This phase will occur first, involving refining the structure and content of the CoDeEndo program, utilizing interviews and focus groups with consumers (i.e. those living with endometriosis) and collaboration with stakeholders (i.e. consumer representatives and endometriosis-related healthcare providers). The frequency and duration of interviews, focus groups, and collaboration will occur on a needs basis throughout this phase and may include for example review of intervention materials, meetings, and online platform feedback. In this phase the final intervention will be created and embedded into an online platform, with the total duration of this phase being 1.5 years.

Phase 2: This phase will follow phase 1, by evaluating the efficacy of the CoDeEndo program. The program will run for 8-weeks and includes 9 interventions each containing a number of sub-modules. The 9 interventions include - Mindfulness, Psychoeducation, Relaxation, Physiotherapy, Acceptance and Commitment Therapy, Hypnotherapy, Yoga, Cognitive Behavioral Therapy, and Dietary Education. Modules are comprised of a mix of video, audio, podcasts, and written resources. Participants will have access to all modules throughout the 8-weeks, allowing for observation of natural use. Participants will also be encouraged to practice (repeat) the modules throughout the 8-weeks. This means that participants can choose to spend as little as 5-mins to several hours per week accessing the CodeEndo Program. Participants will also receive weekly email reminders directing them to CoDeEndo. The specific goals of the intervention will vary for each person, depending on their individual symptoms, severity of disease, expectations and motivations, life experience, and what they want to achieve from the intervention. There are two strategies to monitor adherence to the intervention. 1) The website used to deliver the intervention has an inbuilt tracking system, which is able to provide detailed data regarding participant intervention usage. 2) Also embedded into the website are questions are the end of each module/week asking participants to self-report their usage of the intervention.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
An automated block randomisation sequence with variable block size will be embedded into Qualtrics for allocation concealment. The study biostatistician will not be involved in participant recruitment and will be blinded to group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Consenting participants will be randomly assigned (1:1 ratio) to CodeEndo or Wait-List Control following completion of baseline questionnaire. A block randomisation sequence with variable block size will be embedded into Qualtrics for allocation concealment.

Statistical analyses is planned to be conducted on an intention-to-treat basis. The intervention effect over time (baseline T1, 8-weeks T2, and 6-months T3) on the primary outcomes (EHP-30 and EQ-5D-5L) and the secondary outcomes (all other biopsychosocial outcomes) will be estimated using linear mixed models. The models will include group (intervention, control), time (T1, T2, T3), and group x time interaction effect.

Summary
Brief summary
Endometriosis is a chronic condition in which tissue similar to that lining the uterus grows on other organs, leading to scarring and adhesions and causing pain, menstrual irregularities, and infertility. Impacting 11% of Australian women and those assigned female at birth, endometriosis is under-recognised due to the variability in symptoms, reliance on surgery for diagnosis, and stigma of menstruation. Usual care, comprising of hormone and pain medications, has limited efficacy, is associated with adverse effects, and is discontinued by up to 40% of people. Recognising the inadequacy of the current biomedical healthcare approach to treating endometriosis, there is a need to address the complex psychosocial burden of endometriosis, and there are calls for urgent improvements in access to consumer-centred pain management. The current study will refine the structure and content of 'CodeEndo' – an online modular supportive care program for people living with endometriosis. The project will then evaluate the efficacy of the CodeEndo program using a randomised controlled trial, comparing it to waitlist control on quality of life and other important endometriosis-related biopsychosocial outcomes.

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) may 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.
