老年非恶性肿瘤慢性病患者终末期生存质量量表编制及信效度检验

Development of End-Stage Quality of Life Scale for Elderly Patients with Chronic Non-malignant Disease and Evaluation of Its Reliability and Validity

目的编制老年非恶性肿瘤慢性病患者终末期生存质量评估量表,并评价其信效度。方法以马斯洛需要层次论的XYZ理论为基础,通过文献回顾、半结构式访谈构建量表条目框架;通过专家函询、预调查对量表条目内容进行调整优化,形成量表施测稿;采用便利抽样法,选取2022年5—12月在四川大学华西医院就诊的568例老年非恶性肿瘤慢性病终末期患者为研究对象,进行量表项目分析及信效度检验。结果老年非恶性肿瘤慢性病患者终末期生存质量量表包含4个维度共35个条目。量表总体内容效度指数(S-CVI)为0.96,各条目内容效度指数(I-CVI)为0.83~1.00,与简明健康测量量表简表的关联效度为-0.528,探索性因子分析提取4个公因子,共解释总变异量的50.674%。量表整体Cronbach’sα系数为0.927,重测信度为0.968。结论老年非恶性肿瘤慢性病患者终末期生存质量量表信效度良好,可作为该类人群生存质量的评估工具。

Objective To develop an end-stage quality of life scale for elderly patients with chronic non-malignant disease,and conduct reliability and validity test on it.Methods Under the guidance of the XYZ theory of Maslow's hierarchy of needs theory,the item framework of the scale was formed through literature review and semi-structured interview.The contents and expressions of the scale items were adjusted and optimized by Delphi method and pre-survey,and the scale implementation draft was formed.A total of 568 elderly patients with non-malignant chronic diseases who were admitted to West China Hospital of Sichuan University from May to December 2022 were conveniently selected for questionnaire investigation.Then the scale item analysis and reliability and validity test were carried out.Results The end-stage quality of life scale for elderly patients with chronic non-malignant disease contained 35 items in 4 dimensions.The scale-level content validity index(S-CVI)of the scale was 0.96,item-level content validity index(I-CVI)was 0.83-1.00,and the calibration association validity with Medical Outcomes Study 12-item Short-Form Health Survey(SF-12)was-0.528.The four common factors extracted by exploratory factor analysis accounted for 50.674%of the total variance.The Cronbach'sαcoefficient of the scale was 0.927,and the retest reliability was 0.968.Conclusion The end-stage quality of life scale for elderly patients with chronic non-malignant disease developed in this study has good reliability and validity,and can be used as a tool to evaluate the quality of life of this population.
