Polysymptomatic Distress in Patients With Rheumatoid Arthritis: Understanding Disproportionate Response and Its Spectrum

Abstract

PSD rather than FM diagnosis more usefully identifies and predicts disproportionate responses. Just as there are patients who lean disproportionately toward greater severity, there are also patients who disproportionately report milder symptoms. Composite measures used to assess RA are flawed, as they confound RA inflammation and patient distress, and more consideration should be given to disaggregated assessments. PSD also appears to be influenced weakly by RA disease activity.
