摘要：

目的编制肠内营养再喂养综合征护理知信行问卷并检验其信效度。方法以知信行理论为框架，通过文献分析、德尔菲专家函询和预调查形成肠内营养再喂养综合征护理知信行初始问卷。采用便利抽样法，于2023年8月选取重庆市2所三级甲等医院的350名ICU护士开展调查，进行项目分析、信度检验和探索性因子分析；选取5所三级甲等医院的546名ICU护士开展调查，进行验证性因子分析。结果最终形成的问卷包括3个维度、45个条目。总问卷的Cronbach’s α系数为0.970，分半信度为0.878，重测信度为0.873，平均内容效度指数为0.940。探索性因子分析提取3个公因子，各条目的因子载荷为0.535~0.878，累计方差贡献率为68.683%；验证性因子分析结果显示，模型拟合可接受，问卷结构稳定。结论肠内营养再喂养综合征护理知信行问卷具有良好的信效度，可作为测评ICU护士对肠内营养再喂养综合征认知水平的调查工具。

Abstract:

Objective To develop a Nursing Knowledge-Attitude-Practice Assessment Questionnaire for the Investigation of Enteral Nutrition Refeeding Syndrome and to test its reliability and validity. Methods Based on the theory of knowledge-attitude-practice，an initial questionnaire was developed through literature review，Delphi and pre-survey. 350 ICU nurses from 2 tertiary A hospitals in Chongqing were investigated for item analysis，reliability analysis and exploratory factor analysis in August 2023；another 546 ICU nurses were selected for confirmatory factor analysis from 5 tertiary A hospitals. Results The final questionnaire included 3 dimensions and 45 items. The total Cronbach’s α coefficient，split-half reliability，test-retest reliability and the questionnaire level content validity index were 0.970，0.878，0.873，and 0.940，respectively. Exploratory factor analysis extracted 3 common factors；the factor load of each item ranged from 0.535 to 0.878；the cumulative variance contribution rate was 68.683%. Confirmatory factor analysis showed that the model fit well and the questionnaire’s factor structure was stable. Conclusion The Nursing Knowledge-Attitude-Practice Assessment Questionnaire for the Investigation of Enteral Nutrition Refeeding Syndrome has good reliability and validity，which can be used as a survey tool to evaluate enteral nutrition refeeding syndrome cognitive level of ICU nurses.
