Objectives. The concordance of patient reported outcomes in rheumatoid arthritis (RA) among different countries has not been studied in detail. We tried to determine the differences in pain and fatigue perception among a group of RA patients in the US and in Turkey who had similar disease activity and functional score in multidimensional health assessment questionnaire (MDHAQ FN). Methods. One hundred and thirtyseven RA patients from Turkey and 129 from the US were studied. An MDHAQ was obtained and a DAS-28 was calculated for each patient. Pain and fatigue perception was compared between the two groups after adjusting for age, sex, MDHAQ FN and DAS-28. Results. Turkish patients had less pain than their US counterparts when adjusted for MDHAQ FN, DAS-28, age and sex (3.56 (2.24) vs. 4.35 (2.23), p=0.005) whereas there was no difference in fatigue between the two groups (3.85 (2.44) vs. 4.25 (2.45), p=0.194). When the patients with a DAS-28 score of above 5.1 and below 2.6 were compared in both groups, Turkish patients had again less pain albeit less in the high disease activity group. Conclusion. This study suggests that Turkish patients have less pain than the US patients when controlled for age, gender and MDHAQFN and DAS28 scores. This is at odds to the conventional wisdom that pain perception is increased among the non-Western cultures. © 2010 Copyright CLINICAL AND EXPERIMENTAL RHEUMATOLOGY.
