目的:编制恶性肿瘤患者安宁疗护知识问卷,并检测其信效度。方法:参考安宁疗护实践指南及相关文献形成最初版肿瘤患者安宁疗护知识问卷,采取德尔菲两轮专家咨询法,邀请15名专家对问卷的内容效度进行检验,并选取170名肿瘤患者对问卷的信效度进行检验。结果:该问卷的Cronbanch'sα系数为0. 895,重测信度系数为0. 820,条目水平的内容效度指数(I-CVI)波动在0. 818~1. 00,量表水平的内容效度指数(S-CVI)为0. 910,结构效度(KMO)值为0. 843,Bartlett's球形检验结果为P≤0. 001,共提取2个公因子,解释变量为70. 036%,最终保留12个条目。结论:本研究编制的恶性肿瘤患者安宁疗护知识问卷具有较好的信效度,适合评估肿瘤患者对安宁疗护知识的掌握情况。
Objective:To develop a reliable and valid scale that measures knowledge about hospice care for cancer patient.Methods:An initial questionnaire on the knowledge of hospice care for cancer patients was developed according to hospice care guidelines and relevant articles.Two-round Delphi technique was adopted.Fifteen experts were invited to test the validity of the questionnaire,and 170 patients were selected to test the reliability and validity of the questionnaire.Results:Cronbanch’s alpha was 0.895.The retest reliability was 0.820.I-CVI was 0.818-1.00.S-CVI was 0.910.KMO was 0.843.Bartlett’s Test of Sphericity showed that P<0.001.Two common factors were extracted.The explanatory variable was 70.036%.The formal scale finally included 12 items.Conclusion:The questionnaire compiled in this study has a good reliability and validity,which is suitable for evaluating the knowledge of hospice care for cancer patients.
