The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-Outcome Measures in Rheumatology (OMERACT) Psoriatic Arthritis (PsA) Working Group provided updates at the 2020 GRAPPA annual meeting on its work toward developing a core outcome set for PsA. Working groups were set up for the 4 prioritized domains: enthesitis, fatigue, structural damage, and physical function. Two instruments for measurement of physical function were provisionally endorsed: (1) the Health Assessment Questionnaire-Disability Index and (2) the physical functioning domain in the Medical Outcomes Study 36-item Short Form survey.
