Psychosocial predictors of functional change in recently diagnosed rheumatoid arthritis patients

In order to examine the influence of active and passive pain-coping strategies and social support characteristics on the change in functional status in the first stage: of the disease tn rheumatoid arthritis patients,, self-report data and clinical and laboratory measures were collected from 91-patients (70% female, mean age 57 yr) shortly after diagnosis and 1 yr later. Multiple regression;analyses indicated that, after taking the influence of demographic variables, disease activity and pain,into account, a decrease in functional status (mobility, self-care, grip strength) after 1 yr could be predicted by an initially more;frequent use of the passive pain-coping strategies of worrying and-resting. A decrease in mobility could be additionally predicted by an initially smaller social network. Results indicate the impact of passive pain-coping strategies and social network characteristics for the prognosis of functional outcome in the first stage of the disease and suggest the early;manifestation of avoidance mechanisms; including behavioral, cognitive-emotional and social components, in face of a chronic stressor.
