摘要
目的编制失代偿期肝硬化患者营养素养评估量表并检验其信效度。方法基于Nutbeam健康素养分层模型,通过文献回顾、质性访谈、专家函询和预调查构建量表。通过便利抽样法选取2023年11月至2024年10月于江苏省某三甲医院就诊的406例失代偿期肝硬化患者进行问卷调查,检验量表信效度。结果失代偿期肝硬化患者营养素养评估量表24个条目,探索性因子分析提取出营养态度与知识理解、信息互动与评判、营养实践技能运用3个公因子,累计方差贡献率为66.234%。验证性因子分析示,χ^(2)/df=2.319,GFI=0.805,CFI=0.910,TLI=0.900,RMSEA=0.070。量表水平的内容效度指数为0.910,条目水平的内容效度指数为0.800~1.000。量表Cronbach′sα系数为0.962,半分信度系数0.889,重测信度系数为0.937。结论该量表具有良好的信效度,可作为失代偿期肝硬化患者营养素养水平的有效评估工具。
Objective To develop a nutritional literacy assessment scale for patients with decompensated liver cirrhosis and to evaluate its reliability and validity.Methods Based on Nutbeam′s health literacy framework,the Nutritional Literacy Assessment Scale for Patients with Decompensated Liver Cirrhosis was constructed through literature review,qualitative interviews,expert consultations,and pre-testing.A convenience sampling method was used to select 406 patients with decompensated liver cirrhosis who visited a tertiary hospital in Jiangsu Province from November 2023 to October 2024 for questionnaire survey to assess the scale′s reliability and validity.Results The scale consisted of 24 items.Exploratory factor analysis extracted three common factors:nutritional attitudes and knowledge comprehension,information interaction and judgment,and application of nutritional practice skills,with a cumulative variance contribution rate of 66.234%.Confirmatory factor analysis indicated thatχ^(2)/df=2.319,GFI=0.805,CFI=0.910,TLI=0.900,and RMSEA=0.070.The scale-levle content validity index was 0.910,and the item-level content validity index ranged from 0.800 to 1.000.The Cronbach′sαcoefficient of the scale was 0.962,with a split-half reliability coefficient of 0.889 and a test-retest reliability coefficient of 0.937.Conclusion The assessment scale decompensates good reliability and validity,justifying its use as an effective tool for assessing the nutritional literacy level of patients with decompensated liver cirrhosis.
