Translation, cultural adaptation, and validation of the Portuguese version of ENDOPAIN-4D questionnaire

The Portuguese ENDOPAIN-4D is a culturally adapted and validated instrument for multidimensional pain assessment in European Portuguese women with endometriosis, with validity likely limited for other Portuguese-speaking communities. The newly identified three-factor structure for worst pain may aid individualized pain management and follow-up in clinical and psychosomatic care. Further studies should evaluate concurrent validity and the stability and responsiveness of the new algorithms.
