摘要：

目的 编制ICU医护人员对急性呼吸窘迫综合征（acute respiratory distress syndrome, ARDS）患者俯卧位通气的知信行问卷并进行信效度检验。方法 依据知信行理论模型，通过文献学习、理论分析、专家访谈、德尔菲专家函询、预调查形成初始问卷，于2022年10月—11月选取安徽省7所三级综合性医院的426名ICU医护人员作为调查对象，进行信效度检验；于2023年1月—2月选取该7所三级综合性医院的另外455名ICU医护人员作为调查对象，用于验证性因子分析。结果 最终形成问卷包含知识、信念、行为3个维度，共41个条目；探索性因子分析3个因子累计方差贡献率为65.319%，验证性因子分析各拟合指标均在可接受范围（χ2/df=2.504，RMSEA=0.058，RMR=0.014，IFI=0.933，CFI=0.933，PGFI=0.740，PNFI=0.846，PCFI=0.883）；问卷Cronbach's α系数为0.982，重测信度为0.995，分半信度为0.950。结论 该问卷具有较好的信效度，适用于调查ICU医护人员对ARDS患者俯卧位通气知信行现况。

Abstract: Objective To develop a questionnaire measuring the knowledge，belief，and practice of prone position ventilation for patients with ARDS among ICU medical staff，and to conduct reliability and validity testing. Methods Based on the knowledge，belief，and behavior theory model，an initial questionnaire was formed through literature study，theoretical analysis，expert interviews，Delphi expert consultation，and preliminary surveys. From October to November 2022，426 ICU medical staff from 7 tertiary comprehensive hospitals in Anhui Province were selected as the research subjects for reliability and validity testing. From January to February 2023，another 455 ICU medical staff from 7 tertiary comprehensive hospitals were selected as the survey subjects for confirmatory factor analysis. Results The final questionnaire consisted of three dimensions：knowledge，belief，and behavior，with a total of 41 items. The cumulative variance contribution rate of the three factors in exploratory factor analysis was 65.319%，and all fitting indicators in confirmatory factor analysis were within an acceptable range （χ2/df=2.504，RMSEA=0.058， RMR =0.014，IFI =0.933，CFI =0.933，PGFI =0.740，PNFI =0.846，PCFI =0.883）. Questionnaire Cronbach’s α coefficient was 0.982，the retest reliability was 0.995，and the split half reliability was 0.950. Conclusion This questionnaire has good reliability and validity，and is suitable for investigating the current status of ICU medical staff’s knowledge，belief，and practice of prone ventilation in ARDS patients.
