The Compilation of ICU Nurses’ “Knowledge, Attitude and Practice” Questionnaire for Adult Patients with Mechanical Ventilation through Breath Tube

目的:编制ICU护士对成人经口气管插管机械通气患者口腔护理的“知信行”量表,并对其进行信效度检验。方法:以知信行理论为依据,应用文献回顾、质性研究法、德尔菲专家函询法、小样本预调查法形成初始问卷;应用便利抽样法于2022年3~4月选取山东省潍坊市6所三甲医院的256位ICU护士进行问卷调查。使用SPSS 25.0统计软件对应用问卷进行信效度检验。结果:经过2轮专家函询和预调查后,删除5个条目及修改1个条目的表述方式,形成包含3个维度44个条目的专家函询问卷。经过项目分析后,最终形成正式问卷。问卷信度总Cronbach’s α系数为0.948,折半系数为0.850,内容效度指数I-CVI为0.831,KMO值为0.876,Bartlett’s球形检验的值等于10496.648,P = 0.000,达到显著性水平(P < 0.05)。结论:本研究编制完成的“ICU护士对成人经口气管插管机械通气患者口腔护理‘知信行’问卷”具有良好的信效度,可作为评估护士成人经口气管插管机械通气患者口腔护理“知信行”的有效、科学的工具。

Objective: To develop the knowledge, attitude and practice scale of ICU nurses’ oral care of adult patients with mechanical ventilation through breath tube, and test its reliability and validity. Methods: Based on the theory of knowledge, attitude and practice, the initial questionnaire was formed by literature review, qualitative research, Delphi expert letter inquiry and small sample pre-survey. From March to April 2022, 256 ICU nurses from 6 first-class hospitals in Weifang, Shandong Province were selected by convenience sampling method for the questionnaire survey. SPSS 25.0 statistical software was used to test the reliability and validity of the applied questionnaire. Results: After 2 rounds of expert letter consultation and preliminary survey, 5 items were deleted and the expression of 1 item was modified to form an expert letter consultation questionnaire containing 44 items in 3 dimensions. After the project analysis, the for-mal questionnaire was finally formed. The total Cronbach’s α coefficient of questionnaire reliability was 0.948, the half coefficient was 0.850, the content validity index I-CVI was 0.831, the KMO value was 0.876, and the Bartlett’s sphericity test value was 10496.648, P = 0.000, reaching the signifi-cance level (P < 0.05). Conclusions: The “ICU nurses’ ‘knowledge, trust and practice’ questionnaire of oral care of adult patients with mechanical ventilation through breath tube” compiled in this study has good reliability and validity, and can be used as an effective and scientific tool to evaluate the knowledge, attitude and practice of oral care of adult patients with mechanical ventilation through breath tube.
