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.
背景
慢性疼痛应对量表（CPCI）已被广泛用于测量疼痛应对，但巴西版 CPCI 的心理测量特性尚不清楚。
目的
验证巴西版 CPCI 的有效性和可靠性。
材料和方法
本研究纳入了 705 名慢性疼痛门诊患者。采用 Diagonally Weighted Least Squares 方法进行 Cronbach's alpha 分析、校正项目总分相关性分析和验证性因子分析。
结果
构建效度得到支持，因子负荷范围为 0.36-0.90（9 个因素），与原始负荷相符。排除项目 42 和 54 后，最终模型具有较好的拟合度，DF = 2174，TLI = 0.96；CFI = 0.96，RMSEA = 0.051（p = 0.067）。9 个 CPCI 量表中的 8 个具有良好的可靠性（Cronbach's alpha 范围为 0.70-0.92）。放松量表的 alpha 值较低（0.53）。
结论
排除项目 42 和 54 后，巴西版 CPCI 可有效测量巴西成年人的慢性疼痛应对。
