This study investigated the concordance between clinician and patient assessments of patient’s physical and mental functioning, made using 4-category ordinal scales, for a consecutive sample of 166 outpatients with rheumatoid arthritis. Weighted kappa isn’t a normed statistic, but the respective weighted kappa statistic obtained for the assessments, 0.39 and 0.30, are believed to reflect fair concordance. Data were also analyzed via confirmatory UniODA models which hypothesized that physician and patient ratings agreed. Findings indicated relatively strong concordance for the physical health ratings (ESS=55.5), and moderate concordance for mental health ratings (ESS=43.3).
