虽然已经使用了一些工具来衡量卫生素养，但主要工具的一个关键限制是，它们只衡量阅读能力或印刷能力，在有限的程度上衡量计算能力。因此，本研究旨在开发一种新的工具，使用更全面和基于技能的方法来衡量个人的健康素养。首先，我们确定了一组要演示的技能和要执行的任务。接下来，我们选择现实世界中与健康相关的刺激来测量这些技能，然后我们开发了调查项目。经过一系列认知访谈后，对调查项目进行了修订，发展成为一个38项的工具，并使用基于网络的面板进行试点测试。基于心理测量的属性，我们删除了表现不佳的项目，产生了一个25项的工具，名为健康素养技能工具。在验证性因子分析的基础上，这些项目被分为五个子量表，分别代表散文、文件、定量、口头和基于互联网的信息寻求技能。构念效度与成人功能健康素养测验的简短形式和自我报告技能之间的相关性得到了支持。整体仪器表现出良好的内部一致性，Cronbach's alpha为0.86。计划进行更多的分析，目标是创建该工具的简短形式。
Although a number of instruments have been used to measure health literacy, a key limitation of the leading instruments is that they only measure reading ability or print literacy and, to a limited extent, numeracy. Consequently, the present study aimed to develop a new instrument to measure an individual's health literacy using a more comprehensive and skills-based approach. First, we identified a set of skills to demonstrate and tasks to perform. Next, we selected real-world health-related stimuli to enable measurement of these skills, and then we developed survey items. After a series of cognitive interviews, the survey items were revised, developed into a 38-item instrument, and pilot tested using a Web-based panel. Based on the psychometric properties, we removed items that did not perform as well, resulting in a 25-item instrument named the Health Literacy Skills Instrument. Based on confirmatory factor analysis, the items were grouped into five subscales representing prose, document, quantitative, oral, and Internet-based information seeking skills. Construct validity was supported by correlations with the short form of the Test of Functional Health Literacy in Adults and self-reported skills. The overall instrument demonstrated good internal consistency, with a Cronbach's alpha of 0.86. Additional analyses are planned, with the goal of creating a short form of the instrument.
