摘要
目的 构建缺血性脑卒中术后谵妄风险评估量表,并检验其信效度.方法 采用文献检索、头脑风暴及德尔菲法拟定缺血性脑卒中术后谵妄风险评估量表初稿.采用便利抽样法,选取2020年1月—2021年1月于驻马店市3所三级医院住院的160例缺血性脑卒中手术患者进行调查,对量表初稿进行项目分析、信度及效度检验.结果 构建了包括3个维度、13个条目的缺血性脑卒中术后谵妄风险评估量表.量表条目水平的内容效度指数为0.812～0.962,量表水平的内容效度指数为0.956;探索性因子分子结果显示量表KMO值为0.922,Bartlett's球形检验近似x2值为2 105.652(P＜0.01);13个条目因子载荷均＞0.40,累计方差贡献率为74.221％;总量表Cronbach's α系数为0.931,折半信度0.823,重测信度的组内相关系数为0.826.结论 构建的缺血性脑卒中术后谵妄风险评估量表的信效度较高,可用于缺血性脑卒中术后谵妄发生风险评估.
Abstract
Objective To construct risk assessment scale for postoperative delirium after ischemic stroke and test its reliability and validity.Methods The preliminary draft of the risk assessment scale for postoperative delirium after ischemic stroke was developed by literature search,brainstorming and Delphi method.The convenient sampling method was used to select 160 ischemic stroke patients hospitalized in three tertiary hospitals in Zhumadian City from January 2020 to January 2021 for investigation,and item analysis,reliability and validity test were conducted on the draft scale.Results The risk assessment scale for postoperative delirium after ischemic stroke was constructed,consisting of three dimensions and 13 items.The content validity index of item level was 0.812-0.962,and the content validity index of scale level was 0.956.The exploratory factor analysis results showed that the KMO value of the scale was 0.922,and approximate x2 value of Bartlett's test of sphericity was 2 105.652(P＜0.01).The factor loadings of 13 items were all greater than 0.40,and the cumulative variance contribution rate was 74.221％.Cronbach's α coefficient of the total scale was 0.931,the split-half reliability was 0.823,and the intraclass correlation coefficient of the retest reliability was 0.826.Conclusions The constructed risk assessment scale for postoperative delirium after ischemic stroke has high reliability and validity,which can be used to assess the risk of postoperative delirium after ischemic stroke.
