Takeaway
The Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQv2.1) electronic patient-reported outcome (ePRO) Role Function-Restrictive (RFR) domain is a reliable and validated measure of the functional impact of migraine.
Why this matters
This study demonstrates that this instrument is psychometrically robust and appropriate for inclusion in future migraine studies assessing the impacts of migraine on role functioning.
