Validation Studies of Rheumatoid Arthritis Patient-Reported Outcome Measures in Populations at Risk for Inequity: A Systematic Review and Analysis Using the OMERACT Summary of Measurement Properties Equity Table

•There are few patient-reported outcome measure (PROM) validation studies that have been conducted specifically in rheumatoid arthritis populations at risk for inequity.•The majority of studies identified in our review reported quantitative metrics for construct validity, with few feasibility reports, a paucity of longitudinal studies to determine responsiveness, and rare use of qualitative methods.•We encourage the rheumatology research community to ensure diversity of representation in future PROMs research, ensuring that developed instruments are valid in subpopulations at risk for inequities in rheumatology care.
