Pain Catastrophizing, Subjective Outcomes, and Inflammatory Assessments Including Ultrasound: Results From a Longitudinal Study of Rheumatoid Arthritis Patients

Pain catastrophizing is conceptualized as a negative cognitive–affective response to anticipated or actual pain and has been associated with important pain‐related outcomes. The objective of this prospective study of established rheumatoid arthritis (RA) patients was to explore how pain catastrophizing was related to patient‐reported outcomes (PROs), composite scores, and assessments of inflammatory activity.
