Ph.II: Innovative Methods for Function and Disability Assessment

描述(申请人提供)：我们建议应用创新的测量技术，开发和传播一种用于老年学研究和实践的综合功能和残疾评估工具。该技术为解决传统标准化结果测量技术面临的实用性和心理测量充分性之间的经典冲突提供了一种有效的方法。在这个项目中，我们建议开发、批判性评估和传播晚年功能和残疾工具的计算机适配测试(CAT)工具(Late-Life FDI-CAT)，这是一种有前途的结果工具，旨在全面评估和监测老年人功能和残疾的变化。据我们所知，这在老年学领域以前从未这样做过，是改进结果评估以供老年人使用的一种创新办法。该项目第一阶段的主要目标是：1)在身体功能和残疾领域扩大原有的晚年外国直接投资题库，纳入适合老年人的额外功能和社会角色任务；通过专家反馈、认知测试和焦点小组评估新项目。2)通过收集500名有功能限制和残疾的老年人的不同样本，为修订的晚年外国直接投资题库制定最终项目校准。3)建立一个完全可操作的晚年FDI-CAT系统，并通过真实数据模拟研究证明晚年FDI-CAT的准确性、精确度和应答者负担的减轻。最后，以100名老年人为样本，评价晚年FDI CAT的效度、信度和接受度。这一第二阶段STTR项目的产品将是一种用于老年学研究和临床实践的功能和残疾评估的适销对路的CAT系统。这一新的功能和残疾结果工具改编自固定形式的晚年外国直接投资，将填补实际但高度敏感的评估工具的一个关键空白，该工具专为准确和准确地评估老年人的身体功能和残疾而量身定做。公共卫生相关性：老年人的结果衡量标准正变得越来越重要，并代表着一个主要的公共卫生问题。这一拟议的项目满足了对改进数据收集、数据分析和数据传播方法的需求，这些方法可用于临床应用和公共卫生研究。这一STTR项目的产品将是一种用于评估老年人功能残疾的适销对路的CAT系统。这一新的残疾评估改编自固定形式的晚年外国直接投资，将填补实际但高度敏感的评估系统的关键空白，该评估系统专为准确和准确的身体功能和残疾自我报告评估而量身定做。

DESCRIPTION (provided by applicant): We propose applying innovative measurement technology to develop and disseminate a comprehensive function and disability assessment instrument for use in gerontological research and practice. This technology offers an effective method to resolve the classic conflict between practicality and psychometric adequacy faced by traditional standardized outcome measurement technology. In this project we propose to develop, critically evaluate, and disseminate a Computer-Adapted Testing (CAT) instrument for the Late-Life Function and Disability Instrument (LATE-LIFE FDI-CAT), a promising outcome instrument designed to comprehensively assess and monitor changes in function and disability in older adults. To our knowledge this has never been done before in the field of gerontology and represents an innovative approach to improving outcome assessment for use with older persons. The principal aims of Phase I of this project are to: 1) Expand the original LATE-LIFE FDI item bank in the domains of Physical Function and Disability to incorporate additional functional and social role tasks appropriate for older adults; evaluate new items through expert feedback, cognitive testing and focus groups. 2) Develop final item calibrations for the revised Late-Life FDI item banks by collecting responses from a diverse sample of 500 older adults with functional limitations and disabilities. 3) Create a fully operational LATE-LIFE FDI-CAT system and demonstrate the accuracy, precision, and reductions in respondent burden of the LATE-LIFE FDI- CAT through real data simulation studies. And finally, 4) Evaluate the validity, reliability, and acceptance of the Late-Life FDI CAT in a sample of 100 older adults. The product of this Phase 2 STTR project will be a marketable CAT system for the assessment of function and disability for use in gerontological research and clinical practice. Adapted from the fixed-form, Late-Life FDI, this new function and disability outcome instrument will fill a critical void for a practical yet highly sensitive assessment instrument tailored for accurate and precise assessment of physical function and disability in older adults. PUBLIC HEALTH RELEVANCE: Outcome measures for older adults are becoming increasingly important and represent a major public health concern. This proposed project responds to the need for improved data collection, data analysis and data dissemination methods that can be used in clinical applications and public health research. The product of this STTR project will be a marketable CAT system for the assessment of function disability in older adults. Adapted from the fixed form Late-Life FDI, this new disability assessment will fill a critical void for a practical yet highly sensitive assessment system tailored for accurate and precise self-reported assessment of physical function and disability.
