【摘要】 目的:探讨癌痛自我效能感问卷应用于癌痛患者中的信度和效度。方法:采用癌痛自我效能感问卷调查129例癌痛患者,并进行信度(内部一致性信度、Guttmann折半信度和重测信度)和效度(内容效度、结构效度和效标效度)分析。结果:癌痛管理自我效能感问卷(PSE)、躯体功能自我效能感问卷(FSE)和症状应对自我效能感问卷(CES)的内部一致性信度为0.784~0.886,折半信度为0.767~0.894,重测信度为0.813~0.903,癌痛自我效能感问卷的内部一致性信度为0.897,折半信度为0.885,重测信度为0.864;分问卷与总问卷的相关系数为0.845~0.951,分问卷之间的相关系数为0.672~0.779,P<0.01;提取特征值大于1的因子共3个,累计贡献率为62.56%;三个分问卷与总问卷得分与NRS评分呈显著负相关性,相关系数分别为-0.514、-0.593、-0.447和-0.482(均P<0.01)。结论:癌痛自我效能感问卷应用于癌痛患者具有较好的信度和效度,可用其评价我国癌症患者的癌痛自我效能感。

Reliability and Validity of Cancer Pain Self-efficacy Questionnaire in Cancer Pain Patients/HAN Ling,CHAO Donghua,WU Minhong,et al.//Medical Innovation of China,2018,15(08):132-135
【Abstract】 Objective:To investigate the reliability and validity of cancer pain self-efficacy questionnaire in patients with cancer pain.Method:A total of 129 patients with cancer pain were investigated by using the cancer pain self-efficacy questionnaire,and the reliability(internal consistency reliability,Guttmann fold reliability and retest reliability) and validity(content validity,structural validity and efficiency validity) analysis.Result:The internal consistency reliability of the self-efficacy questionnaire(PSE),physical function self-efficacy questionnaire(FSE) and symptom response self-efficacy questionnaire(CES) were 0.784-0.886,the fold reliability was 0.767-0.894,the reliability of the questionnaire was 0.897-0.903,the internal consistency reliability of the cancer pain self-efficacy questionnaire was 0.897,the folding reliability was 0.885,the retest reliability was 0.864,the correlation coefficient between the questionnaire and the total questionnaire was 0.845-0.951,the correlation coefficient between the three sub-questionnaires was 0.672-0.779,P<0.01,and the total contribution rate was 62.56%.The scores of the three sub-questionnaires and the total questionnaire were negatively correlated with NRS score,the correlation coefficients were -0.514,-0.593,-0.447 and -0.482(P<0.01).Conclusion:The self-efficacy questionnaire of cancer pain is suitable for cancer pain patients with good reliability and validity,and can be used to evaluate the cancer pain self-efficacy of cancer patients in China.

癌痛自我效能感是癌癥患者判断自己能否自我管理癌痛疼痛和能否进行日常生活的能力感知[1]。国内以往的研究表明,慢性疼痛自我效能感量表是一种可用于评价慢性疼痛患者自我效能感的有效评估工具[2-3],然而关于癌症患者专用的癌痛自我效能感量表报道却较少。目前,大部分研究人员采用常规的慢性疼痛自我效能感量表进行相关调查研究[4-5]。本研究将常规的慢性疼痛自我效能感量表进行了适当修订形成了针对癌症患者的癌痛自我效能感问卷,而且分析了问卷的信效度,以期为国内癌症患者的癌痛评估和治疗干预提供科学的参考依据,现报告如下。
