Abstract

Abstract: 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 were 24.86%,21.24%,and 19.33% in order,and the cumulative variance contribution rate was 65.42%. The content validity index（CVI） of the 3 dimensions were 0.962,0.988,and 0.900. The CVI of each item ranged from 0.857 to 1.000. 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.

Key words: Emergency Service,Hospital, Medical Staff, Do-not-resuscitate, Health Knowledge,Attitude,Practice, Reliability, Validity
