Assessing activity limitations experienced by persons with rheumatoid arthritis to inform appropriate selection of patient-reported outcomes measures: a qualitative study

Persons with RA reported a variety of activity limitations across multiple domains, including physical function, telecommunication, social interactions, and other aspects of daily living, which could be a focus for goal-setting communication in the clinical setting. PROMIS PF SF10a may be a more effective and efficient scale to measure 4 sub-categories of daily activity limitations. To more comprehensively assess the spectrum of the impact of RA, it appears advisable to also use PROMIS Fatigue SF7a and APS SF4a to examine General tasks and demands, and Interpersonal interactions and relationships limitations.
