DESCRIPTION (provided by applicant): Operational definition of chronic disability in the National Long-Term Care Survey Abstract: This application requests two years of funding to investigate the operational definition of chronic disability in the National Long-Term Care Survey (NLTCS). Published studies that use data or refer to results from the NLTCS vary in the amount of detail they provide on the definition of chronic disability employed by the survey. Most of these studies, however, oversimplify the NLTCS's operational definition of chronic disability by ignoring longitudinal features of the survey. This practice may lead not only to erroneous conclusions but also to misspecified policy implications. The NLTCS began in 1982 and now extends over six waves through 2004. It provides an important source of information on possible changes in disability over time among the elderly Americans. The NLTCS data on basic and instrumental activities of daily living have been used to generate some major findings such as showing a decline in chronic disability among the elderly Americans. However, complexity of the design, influenced by many decisions made in the early years of the survey, presents conceptual and analytic challenges for secondary users of the NLTCS data. In particular, the operational definition of chronic disability employed by the NLTCS is difficult to track down comprehensively. As a result, it often gets misinterpreted toward an oversimplification. Our preliminary study shows that the NLTCS by design measures some combination of chronic and short term disability as opposed to chronic disability as commonly stated in the literature. The primary aims of this project are to develop a comprehensive description of the operational definition of chronic disability used in the NLTCS and to investigate the impact of the design choices made by the NLTCS on the measurement of chronic disability. This project will illuminate the interplay between the basic definition of chronic disability, as a disability lasting more than 90 days, and the complex longitudinal design of the NLTCS. It will also investigate whether there are subgroups of the elderly population that are differentially affected by the NLTCS design choices as they relate to the measurement of chronic disability. Finally, it will explore whether additional data from the NLTCS can be used to obtain a valid chronic disability measure. Findings of this study will benefit secondary users of the NLTCS data and future designers of longitudinal surveys that aim to track chronic disability status of the elderly over time.

描述(由申请人提供)：国家长期护理调查中慢性残疾的可操作性定义摘要：本申请申请为期两年，用于调查国家长期护理调查中慢性残疾的可操作性定义。使用NLTCS数据或参考NLTCS结果的已发表研究在提供调查所采用的慢性残疾定义的细节方面存在差异。然而，大多数这些研究忽略了调查的纵向特征，过度简化了NLTCS对慢性残疾的可操作性定义。这种做法不仅可能导致错误的结论，还可能导致错误的政策含义。NLTCS始于1982年，目前已延续了六波，一直持续到2004年。它提供了有关美国老年人残疾随时间可能发生变化的重要信息来源。NLTCS关于日常生活的基本和工具性活动的数据被用来产生一些重要的发现，例如显示美国老年人的慢性残疾有所下降。然而，设计的复杂性，受调查最初几年作出的许多决定的影响，给NLTCS数据的二级用户带来了概念和分析方面的挑战。特别是，NLTCS采用的慢性残疾的可操作性定义很难全面追踪。因此，它经常被误解为过于简单化。我们的初步研究表明，NLTCS在设计上衡量的是慢性和短期残疾的某种组合，而不是文献中通常所说的慢性残疾。该项目的主要目的是全面描述国家长期残疾控制系统中使用的慢性残疾的可操作性定义，并调查非长期长期残疾控制系统所作的设计选择对慢性残疾衡量的影响。本项目将阐明慢性残疾的基本定义与NLTCS复杂的纵向设计之间的相互作用，慢性残疾是持续90天以上的残疾。它还将调查是否有不同的老年人口亚群受到NLTCS设计选择的不同影响，因为它们与慢性残疾的衡量有关。最后，它将探索是否可以使用来自NLTCS的额外数据来获得有效的慢性残疾衡量标准。这项研究的结果将使NLTCS数据的二次使用者和未来的纵向调查的设计者受益，这些纵向调查旨在跟踪老年人随时间的慢性残疾状况。国家长期护理调查项目说明中慢性残疾的操作性定义：本申请申请两年的资金，以调查国家长期护理调查(NLTCS)中慢性残疾的操作性定义。使用NLTCS数据或参考NLTCS结果的已发表研究在提供调查所采用的慢性残疾定义的细节方面存在差异。然而，大多数这些研究忽略了调查的纵向特征，过度简化了NLTCS对慢性残疾的可操作性定义。这种做法不仅可能导致错误的结论，还可能导致错误的政策含义。该项目的主要目的是全面描述国家长期残疾控制系统中使用的慢性残疾的可操作性定义，并调查非长期长期残疾控制系统所作的设计选择对慢性残疾衡量的影响。本项目将阐明慢性残疾的基本定义与NLTCS复杂的纵向设计之间的相互作用，慢性残疾是持续90天以上的残疾。它还将调查是否有不同的老年人口亚群受到NLTCS设计选择的不同影响，因为它们与慢性残疾的衡量有关。最后，它将探索是否可以使用来自NLTCS的额外数据来获得有效的慢性残疾衡量标准。这项研究的结果将使NLTCS数据的二次使用者和未来的纵向调查的设计者受益，这些纵向调查旨在跟踪老年人随时间的慢性残疾状况。
