Key result
A biopsychosocial model incorporating physical disability, helplessness, and passive coping explained 29-43% of the variance in pain and 21-33% of the variance in depression over 12 months.

OBJECTIVE: To cross-validate a biopsychosocial model using physical disability, helplessness and passive coping to predict depression and pain in rheumatoid arthritis (RA). METHODS: Clinical and psychological measures were collected from 157 RA patients at three time points over a period of 12 months. Path analysis was used for cross-sectional and longitudinal prediction of depression and pain. RESULTS: Helplessness and passive coping were found to be significant mediators of the relationship between the physical disability and future depression and pain. Cross-sectionally, the predictive model could account for 52-94% of the variance of pain and 37-71% of the variance of depression. Longitudinally, the predictive model could explain 29-43% of the variance of pain and 21-33% of the variance of depression. CONCLUSIONS: These results suggest that physical disability, helplessness and passive coping have a significant impact on the levels of pain and depression experienced by RA patients.

Tanya Covic (2003) conducted a cohort in Rheumatoid arthritis (n=157). Physical disability, helplessness, and passive coping was evaluated on Depression and pain. A biopsychosocial model incorporating physical disability, helplessness, and passive coping explained 29-43% of the variance in pain and 21-33% of the variance in depression over 12 months.
