Description of intervention(s) / exposure
This study aims to determine if health or economic outcomes are improved when women with chronic pelvic pain have group education sessions included in care plans.
Participants with chronic pelvic pain referred to Physiotherapy will be quasi-randomised to one of three arms: 1) suite of scheduled individual consultations over 14 weeks (current/"usual" practice), 2) an introductory group education session attendance followed by a suite of scheduled individual consultations over 14 weeks and 3) an introductory group education session followed by weekly group therapy sessions (8 week program) and a suite of scheduled individual consultations over 14 weeks. Physiotherapy led group sessions will provide education about chronic pain, introduce relevant therapeutic concepts, promote treatment adherence and maintain motivation through regular contact and message reinforcement, and a consumer focus group will provide input to group session content/format. All treatment arms will be provided by Physiotherapists with post graduate qualifications in Women's Health Physiotherapy and a minimum 5 years clinical experience, and all intervention will occur at the Women's and Children's Hospital (Women's Physiotherapy department).
Treatment arm 1: Participants will attend individual face to face consultations with a Physiotherapist, and will undergo comprehensive assessment (subjective, objective) and management. The schedule of consultations is designed to promote motivation and adherence through more regular contact/reinforcement of key messages early in the schedule - participants will attend a 1 hour session, and then 30 min review appointments at 2 weeks / 6 weeks / 10 weeks / 14 weeks. Participants will receive locally developed take home written resources (specific to chronic pelvic pain) and be directed to existing applications/online programs (eg mindfulness applications) to reinforce the care received face to face.
Treatment arm 2: Participants will attend a preliminary group education session (2 hour duration) which will introduce key pain science concepts and chronic pain management strategies, before attending individual consultations (per treatment arm 1).
Treatment arm 3: Participants will attend the preliminary group education session and individual consultations (per treatment arm 2) but will also attend an 8 week group therapy program (1 hour sessions). Each group therapy session will be lead by an experienced Physiotherapist and will include an exercise component as well as a short education topic related to chronic pain management from the multi-disciplinary team. Participants will receive a copy of the commercially available "Explain Pain workbook: Protectometer" (available via http://www.protectometer.com/products.html) to work through over the 8 week group therapy program.

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Women referred to the physiotherapy department for the treatment of CPP will be phoned and asked if they are interested in receiving information on the trial. If so, the trial will be discussed and a short series of screening questions will be completed to ensure suitability for trial inclusion. Purposive sampling will be used to allocate to treatment arm 3, given the potentially onerous time commitment required to complete the treatment arm. Where a participant declines treatment arm 3 but still wishes to participate in the study, they will be randomly allocated to either treatment arm 1 or 2 using allocation by sequentially numbered sealed opaque envelopes containing numbers representative of the 2 therapy arms. The envelopes will put together in a random way by a co-investigator (LH) uninvolved in the allocation process. A participant information sheet and informed consent form will be sent to them and on receipt of signed informed consent form, the co-chief investigator (TB) will open the next sequential envelope and allocate the participant to that arm of the trial. Block randomisation will be used to ensure a spread of women with/without confirmed/suspected endometriosis as well as an equal spread of women aged </> 25 years across treatment arm 1 and 2.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation via random placement of envelopes by co-investigator (LH) uninvolved in allocation process - on receipt of signed written consent form, project coordinator will take the next envelope in sequence for treatment arm allocation (arms 1 and 2)

Efficacy
Statistical methods / analysis
This is a randomised controlled trial (treatment arms 1 and 2) with the primary outcome NRS VAS (numerical rating scale visual analogue scale) assumed to follow normal distribution. A power calculation was based on a mean VAS of 58 with a standard deviation of 21 in a group of women with pelvic pain and endometriosis (Gerlinger et al., 2012). A sample size of n = 22 in each group is required for a two sample non-inferiority trial with a non-inferiority margin = 1.5, sd = 2, alpha = 0.05 and power = 0.80. Assuming a dropout rate of 25%, we will need to randomise 30 subjects to each group. ANCOVA will be used to compare post treatment VAS NRS between groups, adjusting for baseline VAS NRS, age, presence/absence of confirmed endometriosis and use of pain medication during study.
Quantitative analysis of pain assessment/impact scores, absenteeism and physical activity engagement will be undertaken.
