中文版慢性疼痛自我效能感量表用于老年癌痛病人的信效度研究

摘要

目的 探讨慢性疼痛自我效能感量表(Chronic Pain Self-efficacy Scale,CPSS)应用于老年癌痛病人的信、效度.方法 经作者同意后,将英文版的CPSS 翻译、修订后,制定中文版的CPSS,对211 例老年癌痛病人施测,检验量表的内部一致性信度、Guttmann 分半信度、重测信度、内容效度、预测效度和校标效度.结果 量表的内部一致性信度(Cronbach's α)系数是0.896,3个分量表是0.785～0.863;Guttmann 分半信度是0.763～0.896,重测信度是0.810～0.902,分量表与总量表的相关系数是0.755～0.872.总量表和各分量表与NRS 评分的相关系数-0.450～-0.263;因子分析中产生3 个公因子,即疼痛管理自我效能感、躯体性自我效能感、症状应对自我效能感,共能解释总体方差的76.83%,项目的 因子载荷值为0.435～0.854.结论 中文版的CPSS 应用于老年癌痛病人具有较高的信、效度.%Objective To study the reliability and validity of llie Chronic Pain Self-Efficacy Scale (CPSS) in elderly patients with cancer pain. Methods A toial of 211 elderly patients with cancer pain were surveyed with CPSS Chinese version, the results of which were analyzed for its reliability and validity study. Results The total Cror.bacb's a. Coefficient was 0.896, and the Cronbach's a. Coefficients of 3 sub-scales were 0.785-0.863 and Guttmann split-half reliability was 0.763-0.896. Meanwhile, test, -retest reliability was 0.8!.0~0.902 and the correlation coefficient, of subscales and total scale were 0.75 5~ 0.872. The correlation coefficients of score of subscales and total scale with the NRS were -0.450-0.263. Factor analysis generated three common factors: PSE (Self- Efficacy for Pain Management), FSK (Self-I Efficacy for Physical Function) and CSK (Self-Efficacy for Coping with symptoms), which were able to explain the overall variance of 76.83/6 and the factor loading values of item were 0.435-0.854. Conclusion There arc high reliability and validity of the Chinese version of CPSS In elderly cancer patients with pain.
