DESCRIPTION (provided by applicant): General health literacy can be defined as a person's ability to obtain, process, and understand the basic health information needed to make appropriate health care decisions. The Institute of Medicine has put forth a model of health literacy that includes four constructs: 1) cultural and conceptual knowledge, 2) oral literacy (listening and speaking), 3) print literacy (writing and reading) and 4) numeracy. Each construct reflects a set of skills required to function in the health care system and each requires a valid measure to move forward our understanding of the relationship between literacy and health. We propose to develop a new measure of health literacy based upon a conceptual framework of the health numeracy construct. We have developed a conceptual framework of health numeracy that includes the domains of primary numeric skills, applied health numeracy, and interpretive health numeracy. A comprehensive and valid numeracy measure will advance the science of communication and decision-making by: a) providing a tool to describe the level and components of numeracy present in a given individual or population, b) guiding the development of tailored communication and patient educational materials, and c) supporting the development of interventions to improve health numeracy skills. The specific aims in this application are: 1. To develop a measure of health numeracy named the Numeracy Understanding in Medicine Instrument (NUMi). The NUMi will be a. Based upon an empirically derived framework of health numeracy. b. Cross-culturally equivalent across race (black and white) and ethnic (Hispanic and Non-Hispanic) groups. c. Developed using Item Response Theory to ensure that the estimated characteristics of the items are invariant with respect to the sample that is used to evaluate the measure. 2. To establish the reliability and validity of the NUMi a. Internal reliability and parallel-testing reliability will be conducted. b. Content validity will be supported by expert panel review of the numeracy construct, review of the skills identified to reflect the numeracy construct, and review of the items generated for the NUMi instrument. c. Construct validity will tested by evaluating the association of scores on the NUMi with levels of education and existing measures of achievement and health literacy. d. Criterion validity will be tested by evaluating the association of scores on the NUMi with the Medical Data Interpretation Test, the adoption of health protective behaviors, and perceived health.

描述（由申请人提供）：一般健康素养可以定义为一个人获取、处理和理解做出适当医疗保健决策所需的基本健康信息的能力。医学研究所提出了健康素养模型，包括四个结构：1）文化和概念知识，2）口语素养（听和说），3）印刷素养（写作和阅读）和4）算术。每个结构都反映了在医疗保健系统中发挥作用所需的一套技能，并且每个结构都需要有效的措施来推进我们对识字与健康之间关系的理解。我们建议根据健康计算能力构建的概念框架开发一种新的健康素养测量方法。我们开发了一个健康计算的概念框架，包括初级数字技能、应用健康计算和解释性健康计算领域。全面有效的计算能力测量将通过以下方式推进沟通和决策科学：a）提供描述特定个人或群体的计算能力水平和组成部分的工具，b）指导定制沟通和患者教育的发展材料，以及 c) 支持制定干预措施以提高健康计算技能。该应用程序的具体目标是： 1. 开发一种健康算术测量方法，名为医学算术理解工具 (NUMi)。 NUMi 将是：基于经验得出的健康计算框架。 b.跨种族（黑人和白人）和民族（西班牙裔和非西班牙裔）群体的跨文化同等性。 c.使用项目响应理论开发，以确保项目的估计特征相对于用于评估度量的样本保持不变。 2. 确定 NUMi 的可靠性和有效性将进行内部可靠性和并行可靠性测试。 b.内容有效性将得到专家小组对计算能力结构的审查、对反映计算能力结构的技能的审查以及对 NUMi 工具生成的项目的审查的支持。 c.将通过评估 NUMi 分数与教育水平以及现有成就和健康素养衡量标准的关联来测试构建有效性。 d.标准有效性将通过评估 NUMi 分数与医疗数据解释测试、健康保护行为的采用以及健康感知之间的关联来测试。
