Pain in rheumatoid arthritis (RA) is considered to be associated with non-inflammatory factors, including physical disabilities, psychiatric disorders, and pain catastrophizing (PC). PC is reportedly a key driver in the development of pain in patients with RA without clinical signs of inflammation; however, previous studies enroled patients with RA who were potentially in an inflammatory state. Hence, our aim was to investigate the role of PC as the possible link between pain, physical disabilities, and psychiatric disorders in patients with RA without clinical signs of inflammation.
