DESCRIPTION (provided by applicant): The objective of this proposed project is to transform the data collection technology used to assess function and disability in older adults. The proposal responds to NIA's stated priority listed in PA-04-064 to "develop new products that improve data collection, data analysis, and data dissemination of gerontological research." Traditional, fixed-form outcome instruments present serious measurement and practical requirements to identify, track, and evaluate change in function and disability across older age-groups. To address these deficiencies, the principal aims of Phase I are to: (1) build a prototype computerized adaptive testing (CAT) instrument based on an existing Late-Life Function & Disability Instrument (LL-FDI); (2) compare the accuracy, response burden, and sensitivity to change of the prototype LLFDI-CAT with the full-length LL-FDI instrument (LLFDI-Fixed) from an existing database; and (3) evaluate scoring comparability, respondent burden and acceptance of parallel versions of the LLFDI-Fixed and LLFDI-CAT in a pilot test with a sample of disabled older adults. The product in Phase I will be a prototype version of a LLFDI-CAT. In Phase II of the research project, we will examine item calibrations of the original LL-FDI, add new items to broaden the range of coverage and fill in identified gaps, conduct a field study to re-calibrate items, create algorithms for a fully operational LLFDI-CAT system, and implement a dissemination plan. The LLFDI-CAT will fill a critical void for a feasible and psychometrically superior assessment instrument to be used in gerontological research where outcome measures are needed that are comprehensive, sensitive to change, and practical. Relevance to Public Health: Improved instruments are critical for use in and for use in public health research where outcome measures are needed that are comprehensive and sensitive to meaningful change related to interventions designed to improve the health and functioning of older adults and to test the effectiveness of new clinical treatments and interventions. The product of this STTR project will be a marketable Computer Adapted Testing (CAT) version of the Late Life-FDI, an instrument that has great promise to improve function and disability assessment in older persons. Adapted from the Late-Life FDI, this contemporary assessment technology will fill a critical void for a practical and psychometrically superior system that is not currently available for use in public health research. The public health research and clinical communities would be the likely markets interested in the CAT technology that would be developed and evaluated in this STTR.

描述（由申请人提供）：该拟议项目的目标是改变用于评估老年人功能和残疾的数据收集技术。该提案响应了 NIA 在 PA-04-064 中列出的优先事项，即“开发改进老年学研究的数据收集、数据分析和数据传播的新产品”。传统的、固定形式的结果工具提出了严格的测量和实际要求，以识别、跟踪和评估老年人的功能和残疾变化。为了解决这些缺陷，第一阶段的主要目标是：（1）基于现有的晚年功能和残疾仪器（LL-FDI）构建原型计算机自适应测试（CAT）仪器； (2) 将原型 LLFDI-CAT 与现有数据库中的全长 LL-FDI 工具（LLFDI-Fixed）的准确性、响应负担和变化敏感性进行比较； (3) 在样本试点测试中评估 LLFDI-Fixed 和 LLFDI-CAT 平行版本的评分可比性、受访者负担和接受度 的残疾老年人。第一阶段的产品将是 LLFDI-CAT 的原型版本。在研究项目的第二阶段，我们将检查原始LL-FDI的项目校准，添加新项目以扩大覆盖范围并填补已发现的空白，进行实地研究以重新校准项目，为全面的项目创建算法。运作 LLFDI-CAT 系统，并实施传播计划。 LLFDI-CAT 将填补老年学研究中可行且心理测量学上优越的评估工具的关键空白，老年学研究需要全面、对变化敏感且实用的结果测量。与公共卫生的相关性：改进的仪器对于公共卫生研究的使用至关重要，因为公共卫生研究需要全面且敏感的结果测量，这些测量与旨在改善老年人健康和功能的干预措施相关的有意义的变化敏感，并测试其有效性新的临床治疗和干预措施。该 STTR 项目的产品将是 Late Life-FDI 的可销售计算机适应测试 (CAT) 版本，该工具有望改善老年人的功能和残疾评估。这种当代评估技术改编自晚年外国直接投资，将填补实用和心理测量优越系统的关键空白，而该系统目前无法在以下领域使用： 公共卫生研究。公共卫生研究和临床社区将是可能的市场 对本 STTR 中将开发和评估的 CAT 技术感兴趣。
