Endometriosis Pelvic Pain Interdisciplinary Cohort (EPPIC) Data Registry

In collaboration with the BC Women’s Centre for Pelvic Pain and Endometriosis patients with endometriosis and/or pelvic pain have the opportunity to participate in the Endometriosis Pelvic Pain Interdisciplinary Cohort (EPPIC) Data Registry.

The data registry collects longitudinal data reflecting patient history, pain, psycho-social factors, quality of life, physical exam pain mapping, specialized ultrasound results, surgical findings and pathology. This includes the completion of validated questionnaires yearly for 5 years to assess depression (PHQ-9), generalized anxiety (GAD-7), pain catastrophizing (PCS), sleep scale, and endometriosis health profile (EHP-30).

With a goal of better understanding endometriosis we are particularly interested in;

  • predictors of chronic pelvic pain;
  • sexual pain;
  • sexual quality of life;
  • central sensitization;
  • characterizing endometriosis
  • linking gene mutations to clinical symptoms and;
  • exploring transnational and behavioral implications of our research findings.


Data is available on request to qualified investigators as per current ethical approvals and data sharing agreements set by the University of British Columbia Research Ethics Board. Requests for access can be sent to:
