Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Pain reduction on the numeric rating scale [NRS] after 8 weeks. A significant reduction in pain score is defined as a mean difference between groups of at least 1.4 points measured on the NRS. | — |
Secondary
| Measure | Time frame |
|---|---|
| • Quality of life, measured by the Endometriosis Health Profile [EHP-30] (after 8 weeks) • Pain Catastrophizing, measured by the Pain Catastrophizing Scale [PCS] (after 8 weeks) • Affective Symptoms, measured by the Generalized anxiety disorder [GAD-7] and patient health questionnaire [PHQ-9] (after 8 weeks) Outcomes will be assessed by ESM at baseline and after intervention (8 weeks) and results will be compared to the results of the above mentioned validated retrospective questionnaires, measured at 8 weeks. • Pain reduction on the numeric rating scale [NRS] after 4 and 12 weeks. Pain reduction on NRS is assessed by end of week pain score. • Use of analgesics, measured by the BPI questionnaire. • Reduction of dysmenorrhoea on NRS (if applicable) • Reduction of dyspareunia on NRS (if applicable) • The differences in pain reduction on NRS assessed by ESM compared to end of day pain scores [BPI] and end of week pain scores on the NRS. | — |
