Study type
Interventional
Description of intervention(s) / exposure
EndoSMS is a text messaged based intervention that provides supportive messages to individuals living with endometriosis. Messaging covers a range of domains including general endometriosis information, psychological support, self-care and general lifestyle tips. Participants will receive four semi-personalised text messages (e.g., to their preferred name) per week, free of charge, for a period of three months with messages selected from the EndoSMS message bank according to their user characteristics (e.g., smoker vs. non-smoker). Each message is very brief - a maximum of 50 characters and should take less than 1 minute to read.

Behaviour
Comparator / control treatment
Participants randomised to the waitlist control condition will receive no additional support beyond their usual care (e.g., GP/gynaecologist appointments) until the pilot is complete at 3 months and then they will be given the option to receive the text messaging program for a period of 3 months

Secondary outcome [2] 402657 0
User acceptability (e.g., messages easy to understand) is assessed via a self-report online survey using Likert-type questions (i.e., along a scale from Not at all to Very Much so). These questions are derived from questions used in prior research by this team:

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The intervention will be administered entirely online, along with randomisation. Concealment will be by central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomly assigned to conditions using a random generator following completion of the online baseline survey.
Masking / blinding

Statistical methods / analysis
Statistical and thematic analysis will be conducted using SPSS and nVIVO, respectively. With the aim of pilot studies to provide indicative data of an intervention’s potential benefit (Lee et al., 2014), this trial aimed to gain user acceptability and feasibility data to inform a future definitive trial. We will provide confidence interval estimates (95% through 75%) of the range of possible intervention effects for the outcomes of interest. Difference scores (3-month – baseline) are analysed using independent sample t-tests (or Mann-Whitney U-tests for small samples) based on a Minimal Clinically Important Difference (MCID) score for each outcome. Sub-sample analyses are undertaken for: 1) Indigenous only; 2) Taking hormone medication only; 3) Rural/regional located participants only; and 4) Participants indicating having medication taking difficulties. For participants assigned to the Intervention condition, descriptive data were reported regarding user acceptability, along with baseline characteristics of participants completing the study versus those who dropout, and SMS-system delivery data.
