医护人员医疗告知知信行问卷的编制及信效度检验

目的编制和验证医护人员医疗告知知信行问卷,用于评估其现状,为针对性干预提供依据。方法以知信行理论为基础,通过文献回顾、质性访谈、小组讨论、德尔菲专家函询、预调查后形成初测问卷,对438名临床医护人员进行调查,修订问卷并进行信效度检验。结果问卷由知识、态度、行为3个维度共31个条目组成;探索性因子分析3个因子累积方差贡献率为71.906%,验证性因子分析各拟合指标均在可接受范围(χ²/df=3.108,RMSEA=0.098,RMR=0.023,IFI=0.924,CFI=0.924);问卷Cronbach′sα系数为0.948;重测信度为0.973;问卷的S-CVI为0.984,各条目的I-CVI为0.860~1.000。结论该问卷具有较好的信效度,适用于医护人员医疗告知知识、态度和行为现状的调查。

Design, reliability and validity of a knowledge, attitude and practice questionnaire on disclosure of information to patients among medical staff

Objective To design and validate a knowledge,attitude and practice(KAP) questionnaire on disclosure of information to patients among medical staff,and to provide reference for assessment and intervention.Methods Based on the KAP theory,a draft questionnaire was formed through literature review,qualitative interview,group discussion,Delphi expert consultation,and pilot test.A total of 438 clinical medical staff were surveyed to test the reliability and validity of the questionnaire.Results A final questionnaire was produced with 31 items on 3 dimensions:knowledge,attitude and practice.Exploratory factor analysis identified 3 common factors,which could explain 71.906% of the total variance.Confirmatory factor analysis indicated the 3-factor model best matched the data:χ²/df=3.108,RMSEA=0.098,RMR=0.023,IFI=0.924,and CFI=0.924.The Cronbach′s alpha coefficient of the total questionnaire was 0.948 and the test-retest reliability was 0.973.The scale-level content validity index was 0.984,and the item-level CVI ranged from 0.860 to 1.000.Conclusion The questionnaire is reliable and valid for assessing medical staff′s KAP of disclosure of information to patients.
