DESCRIPTION (provided by applicant): This application proposes to continue the National Health and Aging Trend Study (NHATS), which aims (1) to promote scientific inquiry into late-life disability trends and dynamics, their antecedents and correlates, and disparities therein and (2) to advance study of the social and economic consequences of late-life disability for individuals, families, and society. To achieve these aims, in the next 5-year cycle (2014-2018) we will: (a) Collect data in person from the original NHATS cohort annually, including: continued collection of the enhanced disability protocol and supplemental questions on consequences including subjective and economic wellbeing, living and care arrangements, and quality of end of life; collection of dried blood spots, some to be assayed to foster study of the biologic risk for disability progression, and others to be stored for future use; enhancements to the NHATS interview in key understudied areas of potentially growing importance-use of rehabilitation services aimed at recovery from disability, and the service environment and related amenities that promote independent functioning in retirement and senior community settings-and incorporating new modules submitted by the broader research community. (b) Replenish the sample in Round 5 (2015). Replenishment will be implemented in such a way that NHATS maintains the ability to produce 5-year age estimates (including 90+) and Black-White comparisons. (c) Clean, document and disseminate public use files online and continue to make Medicare claims and other sensitive and restricted files available using established procedures. (d) Undertake methodological studies to improve the efficiency of data collection in future rounds, including testing the sensitivity of key estimates to differential follow-up periods and applying modern measurement approaches such as Item Response Theory (IRT) to measures of capacity. The overarching goal of NHATS is to be a platform for scientific inquiry to guide efforts to reduce disability, maximize functioning, and enhance older adults' quality of life. Research using NHATS will foster research to design multi-factor interventions to reduce late-life disability, and will support comprehensive modeling of outcomes of the disability process including living and care arrangements, expenditures, economic well-being, and quality of life.

描述（由申请人提供）：本申请建议继续进行国家健康和老龄化趋势研究（NHATS），其目的是（1）促进对晚年残疾趋势和动态、其前因和相关性以及其中的差异的科学探究， (2) 推进晚年残疾对个人、家庭和社会造成的社会和经济后果的研究。为了实现这些目标，在下一个 5 年周期（2014-2018 年）中，我们将： (a) 每年从原始 NHATS 队列中亲自收集数据，包括： 继续收集增强的残疾协议和关于后果的补充问题，包括主观后果和经济福祉、生活和护理安排以及临终质量；收集干燥的血点，其中一些用于分析以促进对残疾进展的生物风险的研究，另一些则被储存以供将来使用；增强 NHATS 访谈在可能日益重要的关键未研究领域的使用——旨在从残疾中恢复的康复服务，以及促进退休和老年社区环境中独立运作的服务环境和相关便利设施——并纳入更广泛的社区提交的新模块研究社区。 (b) 补充第5轮（2015年）的样本。补充的实施方式应使 NHATS 保持提供 5 岁年龄估计（包括 90 岁以上）和黑白比较的能力。 (c) 在线清理、记录和传播公共使用文件，并继续使用既定程序提供医疗保险索赔和其他敏感和受限文件。 (d) 进行方法学研究，以提高未来几轮数据收集的效率，包括测试关键估计对不同随访期的敏感性，并将项目反应理论（IRT）等现代测量方法应用于能力测量。 NHATS 的总体目标是成为一个科学探究平台，以指导减少残疾、最大限度地发挥功能并提高老年人的生活质量。使用 NHATS 的研究将促进设计多因素干预措施的研究，以减少晚年残疾，并将支持残疾过程结果的综合建模，包括生活和护理安排、支出、经济福祉和生活质量。
