Validity and reliability analysis of the Chinese cancer pain assessment tool

Abstract

目的: 探讨香港钟慧仪博士研制适合中国文化背景的多层面的疼痛评估表 ,《中国人癌症疼痛评估工具》(ChineseCancerPainAssesmenttool,CCPAT) ,的效度与信度。 方法: 测查 319名癌痛患者 ,其中 30名同时用CCPAT和马克盖尔疼痛调查表 (TheMcgillPainQuesionnaire ,MPQ)进行问卷 ,使用因素分析寻找量度疼痛概念有多少因素 ;通过集中癌痛组的CCPAT和MPQ有关项目进行相关总分计算测试 ,确立CCPAT的效度。另抽出 30名患者由两名调查员用CCPAT量表同时进行问卷 ,将CCPAT每一项目作半机率选择 ,计算其信度系数 ,然后将其他患者用CCPAT进行问卷 ,计算其系数的平均值 ,测试在内部的一致性。 结果: 测查 319名癌痛患者 ,CCPA与MPQ的变数相连 ,建立一致的效度 ,比率信度是 0 96 ,内部一致性系数 0 88。 结论: 验证该癌痛评估工具信度、效度良好。对临床评估癌痛病人的疼痛强度有较好的参考价值。 Objective: To discuss the validity and reliability of Chinese cancer pain assessment tool(CCPAT),a multi-layer assessment table that was developed by Doctor Zhong Huiyi from Hong Kong and adapted to Chinese culture background . Method: 319 cases of cancer patients were measured. Among them, 30 patients were questioned by MPQ (the Mcgill pain questionnaire ) and CCPAT.Respectively.Using factor analysis to research for how many factors will influence measured pain concepts .Calculation of total corresponding score was made by gathering all the items of CCPAT and MPQ of the cancer pain group to determine the validity of CCPAT.Other 30 cases of patients were questioned by two investigators. Every factor in CCPAT was carried out half-probability selection and its validity index was calculated.The remaining patients were questioned by CCPAT only .The mean value of the indexes were calculated and the interior coherence was tested . Result: among 319 measured patients ,the variables od CCPAT and MPQ were linked and an accordant validity was established.The rate validity was 0.96 and the interior coherence index was 0.88. Conclusion: CCPAT has a good reliability and validity.It’s a good reference to evaluated the pain intensity of cancer pain patients in clinic.
