胰十二指肠切除术病人家庭肠内营养知信行问卷的研制及信效度检验

Development and reliability and validity test of a home enteral nutrition questionnaire on knowledge⁃attitude⁃practice for patients with pancreaticoduodenectomy

目的:研制胰十二指肠切除术病人家庭肠内营养知信行问卷,并检验其信效度。方法:在文献回顾的基础上,以知信行模式为理论框架,确定问卷条目池内容;经2轮专家函询形成初始问卷;采用便利抽样法选取196例胰十二指肠切除术病人为研究对象,通过临界比值、Pearson相关系数、探索性因子分析、验证性因子分析等检验其信效度。结果:最终问卷包括知识、信念、行为3个维度,共30个条目。总Cronbach’sα系数为0.909,重测信度为0.932。条目水平的内容效度指数为0.830~1.000,问卷水平的内容效度指数为0.969。问卷KMO值为0.832,探索性因子分析共提取出3个公因子,累计方差贡献率为77.620%。验证性因子分析显示各指标拟合度较好。结论:胰十二指肠切除术病人家庭肠内营养知信行问卷具有良好的信效度,可作为调查胰十二指肠切除术病人家庭肠内营养知信行水平的客观测评工具。

Objective:To develop a home enteral nutrition questionnaire on knowledge⁃attitude⁃practice for patients with pancreaticoduodenectomy and test its reliability and validity.Methods:On the basis of literature review and qualitative interview,the contents of the questionnaire item pool were determined based on the theoretical framework of knowledge,belief and action model.The initial questionnaire was formed after two rounds of expert letter consultation;Convenience sampling method was used to select 215 patients with pancreaticoduodenectomy as subjects,and the reliability and validity were tested by critical ratio method,Pearson correlation coefficient method,exploratory factor analysis and confirmatory factor analysis.Results:The final questionnaire consisted of 30 items from three dimensions of knowledge,belief and behavior,with a total Cronbach'sαcoefficient of 0.909 and a retest reliability of 0.932.Item level I⁃CVI was 0.830⁃1.000,and questionnaire level S⁃CVI was 0.969.The KMO value of the questionnaire was 0.832,and three common factors were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 77.620%.Confirmatory factor analysis showed that the fitting degree of each index was good.Conclusion:The home enteral nutrition questionnaire on knowledge-attitude-practice for patients with pancreaticoduodenectomy questionnaire has good reliability and validity,and can be used as an objective evaluation tool to investigate the knowledge and practice level of home enteral nutrition in patients with pancreaticoduodenectomy.
