The Chronic Pain Coping Inventory (CPCI) is a frequently used measure that assesses 8 categories of coping strategies that patients might use to cope with chronic pain. Despite its good psychometric properties and widespread use, the instrument has not been tested for its applicability and validity in non-Western populations, such as among Chinese. This study evaluated the reliability and validity of a Chinese translation of the 42-item CPCI (ChCPCI-42) in a sample of Chinese patients with chronic pain (n = 208). In addition to the ChCPCI-42, the patients were administered the Chronic Pain Grade (CPG) questionnaire, the Pain Catastrophizing Scale (PCS), the Centre for Epidemiological Studies-Depression Scale (CES-D), and questions assessing sociodemographic characteristics. Results of confirmatory factor analyses revealed that of the ChCPCI-42 8 scales, 6 demonstrated acceptable-to-good data-model fit (CFI >or= 0.90) and 2 demonstrated medium fit (CFI >or= 0.85). The 8 scales demonstrated adequate to good internal consistency (Cronbach alpha, 0.69 to 0.79) and correlated with CES-D, PCS, pain intensity, and disability in expected directions. Results of hierarchical multiple regression analyses showed that the ChCPCI-42 scales predicted concurrent depression (F (8,177) = 3.07, P < .01) and pain disability (F (1, 179) = 4.35, P < .001) scores, the Task Persistence scale being the strongest unique predictor among the 8 scales. The findings support the factorial validity and reliability of a 42-item CPCI that can be used among Chinese patients with chronic pain.
The report outlines the first validation of the CPCI for use in Hong Kong Chinese. This makes available a suitable instrument for chronic pain research in the Southern Chinese population and will help to elucidate similarities and differences in pain coping between Chinese and other ethnic groups.
慢性疼痛应对量表（CPCI）是一种常用的评估患者可能用于应对慢性疼痛的 8 种应对策略的量表。尽管它具有良好的心理测量学特性和广泛的应用，但该工具尚未在非西方人群中（如中国人）进行适用性和有效性测试。本研究评估了慢性疼痛患者（n = 208）样本中 42 项 CPCI（ChCPCI-42）中文翻译的信度和效度。除了 ChCPCI-42，患者还接受了慢性疼痛量表（CPG）、疼痛灾难化量表（PCS）、流行病学研究中心抑郁量表（CES-D）和评估社会人口学特征的问题。验证性因素分析的结果表明，在 ChCPCI-42 的 8 个量表中，有 6 个量表显示出可接受至良好的数据模型拟合（CFI≥0.90），有 2 个量表显示出中等拟合（CFI≥0.85）。8 个量表表现出足够至良好的内部一致性（Cronbach α，0.69 至 0.79），并与 CES-D、PCS、疼痛强度和残疾呈预期方向相关。分层多元回归分析的结果表明，ChCPCI-42 量表预测了抑郁的共变量（F（8,177）=3.07，P<.01）和疼痛残疾（F（1,179）=4.35，P<.001），任务坚持量表是 8 个量表中最强的独特预测因素。这些发现支持了用于中国慢性疼痛患者的 42 项 CPCI 的因子有效性和可靠性。
该报告概述了 CPCI 在香港中国人中的首次验证。这为南方中国人慢性疼痛研究提供了一种合适的工具，并将有助于阐明中国人与其他族裔在疼痛应对方面的相似性和差异。
