Background
The Chronic Pain Coping Inventory (CPCI) has been widely used to measure coping with pain, however, the psychometric properties of the Brazilian CPCI are unknown.
Aim
To verify the validity and reliability of the CPCI-Brazilian version.
Materials and methods
A sample of 705 outpatients with chronic pain participated in the study. Cronbach’s alpha, corrected item-total correlations, and confirmatory factor analysis were performed, using the method of Diagonally Weighted Least Squares.
Results
Construct validity was supported with a factor loading range of 0.36–0.90 (9 factors) corroborating original loads. The final model had adequate fit with items 42 and 54 excluded, D.F = 2174, TLI = 0.96; CFI = 0.96 and RMSEA = 0.051(p = 0.067). Eight of the nine CPCI scales showed satisfactory reliability (Cronbach’s alpha ranged from 0.70 to 0.92). The Relaxation scale obtained a low alpha value (0.53).
Conclusion
The CPCI-Brazilian version, after exclusion of items 42 and 54, is valid to measure chronic pain coping in Brazilian adults.
