急诊医护人员启动不复苏知信行量表的编制及信效度检验

Development and psychometric testing of Knowledge-Attitude-Practice Scale on Initiating Do-Not-Resuscitate among emergency medical staff

目的 编制急诊医护人员启动不复苏知信行量表,并进行信效度检验。方法 通过文献回顾法和专家函询法形成预测试量表。2020年8月,便利选取浙江省2所三级甲等医院急诊室的181名医护人员进行调查,对量表进行项目分析和信效度检验。结果 急诊医护人员启动不复苏知信行量表共3个维度、31个条目。其中知识维度10个条目、态度维度11个条目、行为维度10个条目。启动不复苏知识、态度、行为3个维度方差贡献率依次为24.86%、21.24%、19.33%,累计方差贡献率为65.42%,平均内容效度指数分别为0.962、0.988、0.900,各条目的内容效度指数为0.857~1.000。该量表总Cronbach’s α系数为0.953,各维度的Cronbach’s α系数为0.919~0.940;总折半信度为0.770,各维度的折半信度为0.843~0.909。结论 急诊医护人员启动不复苏知信行量表具有较好的信效度,可用于急诊医护人员启动不复苏认知与行为水平评估。

Objective To develop Knowledge-Attitude-Practice Scale of Initiating Do-Not-Resuscitate(DNR) among emergency medical staff,and to evaluate the reliability and validity. Methods We formed a pretest scale by literature review and expert consultation. To analyze items of the scale and test the reliability and validity,we processed a survey among 181 medical staff with initiating DNR Knowledge-Attitude-Practice Scale in emergency department of two tertiary hospitals in Zhejiang at August 2020. Participants were selected by convenience sampling. Results The Knowledge-Attitude-Practice Scale on Initiating DNR among emergency medical staff has 31 items and 3 dimensions. There were 10 items in the knowledge dimension,11 items in the attitude dimension,and 10 items in the practice dimension. The variance contribution rate of knowledge,attitude and practice on initiating DNR were24.86%,21.24%,and 19.33% in order,and the cumulative variance contribution rate was 65.42%. The content va lidity index(CVI) of the 3 dimensions were 0.962,0.988,and 0.900. The CVI of each item ranged from 0.857 to1.000. The Cronbach’s α coefficients of the scale was 0.953,and the Cronbach’s α coefficients of each dimension ranged from 0.919 to 0.940. The total split-half reliability coefficient of the scale was 0.770,and the split-half reliability coefficient of each dimension ranged from 0.843 to 0.909. Conclusion The Knowledge-Attitude-Practice Scale of Initiating Do-Not-Resuscitate(DNR) among emergency medical staff has good reliability and validity,and it can be used to evaluate the initiation of DNR knowledge and behavior level of emergency medical staff in China.
