Description of intervention(s) / exposure
Participants are asked to complete questionnaires at baseline and annually thereafter for up to 5 years (or until 31/12/2027). The questionnaires cover periods, pain, quality of life, depression, anxiety, personality traits and adverse childhood events. The number of questionnaires depends on the age of the participant and is detailed in the study protocol and accompanying PICFs.
-For child/young person the questionnaires for the research project will take around 45 minutes of the child’s time, per year.
-For parent/guardian the questionnaires for the research project will take around 30 minutes of your time, per year.
The mode of delivery for all questionnaires is via email for completion online.

Participants are also invited to participate in pain-orientated sensitivity testing (POST) which is performed face-to-face using a calibrated algometer. POST appointments take up to 30 minutes for both the child/young person and their parent/guardian.

Health care utilisation (for children/young people) will be assessed by data linkage to Medicare Benefits Scheme (MBS) and Pharmaceutical Benefits Scheme (PBS) data. This requires the participant or parent/guardian (depending on age) to complete a separate participant consent form for the release of Services Australia information.

Statistical methods / analysis
Data will be analysed to obtain an overarching view of period, pelvic and endometriosis in participants and the characteristics of those that present with pain. We will use multivariate linear and logistic regression analysis to explore. Data will be analysed to describe pain, mental health and health utilisation outcomes controlling for relevant confounding factors.
