Abstract

Background: Toward delivering appropriately safe, high quality and effective health care, healthcare organization should be health literate. This paper presents the development and psychometrics of an instrument for assessing the attributes of a health literate hospital which is called MAHLO-76 (Measure to Assess Health Literate Organization) here by authors.

Methods: The current study is methodological research which is involved two phases of tool development and psychometric evaluation. MAHLO primary item pool was prepared using the data extracted from the semi-structured, in-depth interviews and literature review. The face and content validity were evaluated applying qualitative and quantitative approaches. Exploratory factor analysis with varimax rotation after Bartlett sphericity and KMO tests was used to evaluate the construct validity. Confirmatory factor analysis was conducted to evaluate the structural factors, applying the most common goodness-of-fit indices. In order to determine internal consistency and test-retest stability, Cronbach's alpha and intra-class correlation coefficient were calculated respectively.

Results: The initial tool after checking for duplicates and excluding was contained 79 items. In terms of face validity, 3 items were modified using qualitative method and none of the items had an impact score of less than 1.5. In the qualitative content validity assessment, 16 items were revised and none of the items had CVR score less than 0.59 and CVI score less than 0.79. The results of the EFA obtained from the KMO showed the adequacy of the sample size (KMO value = 0.884) and the Bartlett's sphericity test showed a significant correlation between the items (χ2 = 38124.040, df = 3081, P < 0.0001). The exploratory factor analysis indicated that 14 initially extracted factors explained 63.716% of the total variance. In Confirmatory factor analysis, the chi-square was 205.016 and other model fit indices including NFI:0.812, NNFI:0.875, CFI:0.919, IFI:0.921, MFI:0.857, GFI:0.930, AGFI:0.918, RMR:0.051, RMSEA:0.06 were calculated. In reliability assessment, Cronbach's alpha was 0.94 and the value of ICC was 0.98.

Conclusion: Measure to Assess Health Literate Organization (MAHLO-76) is a valid and reliable instrument that can be used as assessment as well as self-assessment tool in hospital settings. Its application could disclosure those organizational health literacy aspects in clinical environments that need necessary interventions.

医院环境中健康素养组织评估新措施(MAHLO-76)的发展和心理测量特性的方法学研究。
背景:为了提供适当的安全、高质量和有效的医疗保健,医疗保健机构应该具有健康素养。本文介绍了一种用于评估卫生素养医院属性的工具的开发和心理测量学,该工具被称为MAHLO-76(评估卫生素养组织的措施)。方法:目前的研究是方法论研究,包括工具开发和心理测量评估两个阶段。MAHLO主要项目池的数据提取自半结构化、深度访谈和文献综述。采用定性和定量的方法来评估表面效度和内容效度。采用Bartlett球度检验和KMO检验后的变量旋转探索性因子分析来评估构念效度。采用最常用的拟合优度指标,进行验证性因子分析来评价结构因素。为了确定内部一致性和重测稳定性,分别计算Cronbach’s alpha和intra-class相关系数。结果:经重复剔除后的初始工具包含79个项目。在面子效度方面,有3个条目采用定性方法进行了修改,没有一个条目的影响得分低于1.5。在定性内容效度评价中,共修改了16个项目,没有一个项目的CVR得分低于0.59,没有一个项目的CVI得分低于0.79。从KMO获得的EFA结果显示样本量的充分性(KMO值= 0.884),Bartlett's球形检验显示各项目之间存在显著相关性(χ2 = 38124.040, df = 3081, P)。结论:MAHLO-76是一种有效可靠的健康素养组织评估工具,既可以作为医院环境中的评估工具,也可以作为自我评估工具。它的应用可以揭示临床环境中需要必要干预的组织健康素养方面。
