麻醉恢复室护士对全麻术后患者低体温管理知信行问卷的编制与信效度检验

Development of knowledge-attitude-practice questionnaire about post-anesthesia care unit nurses'hypothermia management for patients after general anesthesia and its reliability and validity test

目的编制麻醉恢复室(PACU)护士对全麻术后患者低体温管理知信行(KAP)问卷,并检验其信效度。方法基于循证总结PACU全麻术后患者低体温管理最佳证据,以知信行理论为指导提取证据,构建问卷条目池,通过小组讨论、德尔菲专家函询、预调查修订问卷条目。采用便利抽样法选取全国110所医院465名PACU护士进行问卷调查,以检验问卷信效度。结果最终问卷含知识、态度和行为3个维度,共43个条目,其中知识维度含15条客观题,信念和行为维度分别含13和15个条目,采用Likert 5级评分法作答。信念维度和行为维度Cronbach′sα系数分别为0.989和0.926,总Cronbach′sα系数0.956;重测信度0.879;条目水平的内容效度指数(I-CVI)为0.800~1.000,平均内容效度指数(S-CVI)0.985;探索性因子分析萃取3个公因子,累计方差贡献率为74.22%。结论PACU护士对全麻术后患者低体温管理的KAP问卷信度和效度良好,适用于PACU护士对全麻术后患者低体温知识、态度和行为现状的调查。

Objective To develop a knowledge-attitude-practice(KAP)questionnaire of post-anesthesia care unit(PACU)nurses'hypothermia management for patients after general anesthesia,and to test the reliability and validity of the questionnaire.Methods Summarized the best evidence for the prevention and management of hypothermia in patients after general anesthesia in PACU based on the evidence-based theory,and the first draft of the questionnaire was prepared based on KAP theory.Then the questionnaire items were revised through group discussion,Delphi expert correspondence,and pre-investigation.After that,465 nurses in PACU from 110 hospitals across China were selected for a questionnaire survey by convenience sampling method to test the reliability and validity of the questionnaire.Results The final questionnaire included 43 items from 3 dimensions of knowledge,attitude,and practice,among which the knowledge dimension contained 15 objective questions,and the belief and behavior dimensions contained 13 and 15 items,respectively,which are answered by the Likert 5-level scoring method.The Cronbach'sαof the attitude and practice dimensions were 0.989 and 0.926,respectively,and the Cronbach'sαfor the total scale was 0.956.The test-retest reliability was 0.879.The item-content validity index(I-CVI)ranged from 0.800 to 1.000,and the average scale-content validity index(S-CVI)was 0.985.Three common factors were extracted by exploratory factor analysis and the rate of cumulative variance contribution was 74.22%.Conclusion The reliability and validity of PACU nurses'KAP questionnaire on hypothermia management of patients after general anesthesia are good,which is suitable for the investigation of knowledge,attitude,and behavior status of PACU nurses on hypothermia management of patients after general anesthesia.
