DESCRIPTION (provided by applicant): Health literacy has emerged as a critically important factor in health outcomes. Although existing measures of health literacy have distinct advantages and have been useful in research and clinical practice, each has characteristics that reduce its usefulness with some populations. The core aim of this application will be to develop a new health literacy measure with content, linguistic, and psychometric properties that will make it more broadly useful for screening and diagnostic purposes in clinical and research populations. It will be administered using computer touch screen technology to make the measure easily administered and scored and readily accessible via computers or the Internet. During development the measure will be validated by assessing its relations to other measures and participants' health. The planned development process will use item response theory (IRT) methods to develop a measure that functions equivalently in both Spanish and English and with younger and older persons. Its content will be broadly based following the recommendations health literacy experts and include audio and video items to enhance the measure's interest and validity. The measure will be computer administered using touch screen technology so that when deployed it may be self-administered and scored. The measure will be developed in two phases. We will first generate approximately 200 candidate items by rationally creating items of various levels of difficulty within broad content areas related to health literacy based on the content areas described in the Institute of Medicine report on health literacy (Nielsen-Bohlman et al., 2004). Items will be generated in Spanish or English and then translated and back translated into and from each language to ensure that their content is equivalent in both languages. We will then pilot test these candidate items in Spanish and English with 75 persons from each language group across several age ranges, drawing on persons aged 18 years and older. Items will be qualitatively evaluated using participant feedback and quantitatively using nonparametric IRT methods Items will be selected from the larger item pool for testing with larger groups of 30 persons in each decade of age from the 20s to 80s in both Spanish and English, so that 60 persons in each decade will be involved in the second phase of scale development for a total of 420 persons. The measure will be validated by assessing its relations with currently-used measures of health literacy, cognitive and academic measures, and health status, health care-related quality of life, and utilization of healthcare services. The creation of an easily-administered measure of health literacy will further the goals of this program announcement that requests applications focused on improved measures of health literacy. The new measure will be readily deployed over the Web. Future development will allow the creation of a computerized adaptive measure of health literacy and integrated tailored information applications to improve health literacy. PUBLIC HEALTH RELEVANCE: Health literacy is a critically important public health problem but current measures of it are inadequate. The application to be developed in this application will address this problem by creating a computer-administered measure of health literacy that is useful across age and language groups and is cost-effective to use.

描述（由申请人提供）：健康素养已成为健康成果的至关重要的因素。尽管现有的健康素养措施具有明显的优势，并且在研究和临床实践中很有用，但每个人都具有降低其对某些人群的有用性的特征。该应用程序的核心目的是使用内容，语言和心理测量学特性制定新的健康素养措施，这将使其对于临床和研究人群的筛查和诊断目的更为广泛。它将使用计算机触摸屏技术进行管理，以使该措施轻松地管理和评分，并可以通过计算机或Internet访问。在开发过程中，该措施将通过评估其与其他措施和参与者健康的关系来验证。 计划的发展过程将使用项目响应理论（IRT）方法来开发一种在西班牙语和英语以及年轻和老年人中等效起作用的度量。它的内容将大致遵循健康素养专家的建议，并包括音频和视频项目，以增强措施的兴趣和有效性。该措施将使用触摸屏技术进行计算机管理，以便在部署时可以自我管理和评分。 该度量将分为两个阶段。我们将根据医学研究所中描述的健康素养报告中所述的内容领域，在与健康素养有关的广泛内容领域中合理地创建与健康素养有关的各种难度的项目，首先生成大约200个候选项目（Nielsen-Bohlman等，2004）。项目将以西班牙语或英语生成，然后翻译并从每种语言中转换为转换和返回，以确保其内容在两种语言中相当。然后，我们将以西班牙语和英语为西班牙语和英语测试这些候选物品，其中包括18岁及以上的人的每个语言组的75人。项目将使用参与者反馈对项目进行定性评估，并使用非参数IRT方法进行定量评估项目项目将从较大的项目池中选择，以在每个十年中的20年代至80岁之间的西班牙语和英语中的30人中进行测试，以便在每个十年中的60人将参与第二阶段的第二阶段，共有420人。该措施将通过评估其与当前使用的健康素养，认知和学术措施以及健康状况，与医疗保健相关的生活质量以及医疗保健服务的利用的关系来验证。 建立易于管理的健康素养衡量标准将进一步进一步，以提出该计划公告的目标，该公告要求申请专注于改进的健康素养衡量标准。新措施将很容易通过网络部署。未来的开发将允许创建用于健康素养的计算机化自适应度量，并综合量身定制的信息应用程序，以提高健康素养。 公共卫生相关性：健康素养是一个至关重要的公共卫生问题，但目前的措施不足。在本应用程序中开发的应用程序将通过创建一个具有计算机管理的健康素养衡量标准来解决此问题，该素养在跨年龄和语言群体中很有用，并且具有成本效益。
