    一种成年人营养素养测量量表的编制及信效度评价

    Development of a nutritional literacy assessment scale for adults and its evaluation of reliability and validity

      摘要
    • 摘要:
      目的筛选成年人营养素养测评量表条目，并验证其信效度，为评价成年人的营养素养水平提供一个测量工具。
      方法通过文献综述法形成量表条目池，通过Delphi专家咨询对量表进行初步筛选后形成营养素养初始调查问卷，线上调查1 718名成年人后收集结果，结合临界比值法、校正题项-总相关系数法和因子分析法进一步筛选条目，并使用Cronbach's α系数和折半信度系数来检验量表的信度，从内容效度和结构效度两方面检验量表的效度。
      结果本研究成年人营养素养量表包括功能性营养素养（包括知识储备、知识理解、获取技能和应用技能4个领域）、互动性营养素养（互动技能领域）和评判性营养素养（评判技能领域）3个方面，总共43项条目。总量表的Cronbach's α系数为0.971，折半信度系数为0.855；量表水平的内容效度指数为0.982，条目水平的内容效度指数为0.846~1.000；验证性因子分析结果显示6个维度的标准化因子载荷0.463~0.938，平均方差萃取值0.552~0.807，组合信度值0.860~0.961。
      结论该量表具有良好的信度和效度，可用于成年人营养素养水平的测量。

       

      Abstract:
      ObjectiveTo screen the items of the adult nutrition literacy assessment scale, and verify its reliability and validity for providing a tool to assess the nutritional literacy levels of adults.
      MethodsThe literature review was used to form the item pool, the initial nutrition literacy questionnaire was developed by Delphi consultation, and the results of online questionnaires of 1 718 adults were collected for further filtering entries combined with critical ration method, correction item-total correlation coefficient method and factor analysis method.The reliability of scale was tested using the Cronbach's α coefficient and Split-Half coefficient, and the validity of scale was tested in terms of content validity and structure validity.
      ResultsThe nutritional literacy assessment scale included the functional nutrition literacy(including knowledge, understanding, obtaining skills and applying skills), interactive nutrition literacy(interactive skills) and critical nutrition literacy(critical skills), a total of 43 items.The Cronbach's α coefficient and Split-half reliability coefficient of total scale were 0.971 and 0.855, respectively.The content validity index at scale level and item level were 0.982 and 0.846-1.000, respectively.The results of confirmatory factor analysis showed that the standardized factor load, AVE value and CR value of the six dimensions were 0.463-0.938, 0.552-0.807 and 0.860-0.961, respectively.
      ConclusionsThe reliability and validity of the nutrition literacy assessment scale are good, and it can be used to assess the nutritional literacy for adults.
