Abstract

Most indigenous populations in developing counties are burdened by limited health literacy, and validated, cultural and language-specific health literacy measures are not available for them. This article describes a phased approach that was followed to validate the Sesotho Health Literacy Test (SHLT). Data from 474 patients and high school learners were used to test understandability of SHLT items, item response, factor analysis, and convergent and predictive validity of test items. SHLT items showed good internal reliability (Cronbach's α = 0.77). Exploratory structural equation modelling showed acceptable fit as the standardized root-mean-square residual (SRMR = 0.04). The convergent validity of the SHLT was good, indicated by people with more years of formal schooling scoring higher on the SHLT. The predictive validity of the SHLT was good, as those participants who scored high on the SHLT never had reading assistance. The test can be used by practitioners before they implement health promotion.

摘要

发展中县的大多数土著人口承受着有限的健康素养负担，并且他们无法获得经过验证的，针对文化和语言的健康素养措施。本文介绍了一种阶段性方法，可以用来验证Sesotho健康素养测试（SHLT）。来自474名患者和高中学习者的数据用于测试SHLT项目的可理解性，项目反应，因素分析以及测试项目的收敛性和预测有效性。SHLT项目显示出良好的内部可靠性（Cronbachα= 0.77）。探索性结构方程建模显示可接受的拟合为标准均方根残差（SRMR = 0.04）。SHLT的收敛效度很好，这是因为受过正规教育的年限较长的人在SHLT上得分更高。SHLT的预测有效性很好，因为那些在SHLT上得分高的参与者从未获得过阅读帮助。练习者可以在健康促进之前使用该测试。
