State and trait pain catastrophizing and emotional health in rheumatoid arthritis.
BACKGROUND
Pain catastrophizing is a powerful predictor of pain adaptation, and both stable and time-varying aspects may influence overall emotional well-being.


OBJECTIVE
This study aims to test the independent influences of state and trait pain catastrophizing on the relationship between daily intensity and negative affect, positive affect, and depressive symptoms.


METHODS
Daily diary data were collected for 30 days from a sample of 231 adults with a diagnosis of rheumatoid arthritis.


RESULTS
State pain catastrophizing accounted for a significant proportion of the relationship between daily pain and each of the three examined daily outcomes. Greater trait pain catastrophizing significantly increased the effect of state pain catastrophizing on the relationship between pain intensity and the outcome variables in cross-sectional and time-lagged models.


CONCLUSIONS
The results of the current study indicate that state pain catastrophizing plays a prominent role in the adaptation to daily pain fluctuations, particularly for those with a propensity to catastrophize.
