The origins of depressed mood in rheumatoid arthritis.
Most studies that have considered depressed mood in patients with rheumatoid arthritis have failed to analyze the relative contribution of psychological, social and disease state variables. Using multivariate statistical analyses we identified the role played by demographic, disease related, disability and social variables. Together these variables accounted for 44% of the variation in depressed mood. Demographic factors, disability measures, disease duration, social isolation and economic deprivation all made significant contributions to the explanation of depressed mood. The results of our study underline the importance of examining a wide range of factors in order to consider their relative influence on psychological state.
