项目摘要 老年人口的迅速增加激发了人们对正常人的强烈科学兴趣。 以及老年人的病态认知功能。随着年龄的增长， 像阿尔茨海默氏病这样的衰弱性疾病导致了对临床和研究方法的需求， 测量这些疾病的影响，认知测试在检测，诊断和治疗方面发挥着重要作用。 监测疾病状态和进展。人口结构日益多样化， 认知的精确测量。大多数临床和研究使用的认知测试都是在 使用的是世纪上半叶的心理测量方法。在以下方面取得了重大进展： 测量理论和方法，特别是项目反应理论（IRT）和相关的潜在变量 建模方法，这可能对认知的测量产生重要影响。有 纵向认知轨迹建模和识别的统计方法学的平行进展 对这些重要结果产生积极和消极影响的变量。本次会议旨在 促进现代心理测量学和统计学方法在认知老化研究中的应用。 具体目标是：1）使认知老化领域的发展中和成熟的研究人员了解现代 心理测量和统计建模技术，2）让心理测量理论和统计学专家了解 认知老化研究的实践和理论问题，以及3）鼓励合作， 研究人员，心理测量学家和统计学家在这些会议上。我们已经进行了九次 自2008年首次获得该赠款以来，成功举办了年度会议，并计划举办第10次会议。 2017年9月。迄今为止，该系列已产生59份合作出版物。这一经验有助于 为下一代会议制定计划。会议的形式将包括教学 认知老化和应用心理测量学理论专家的介绍，心理测量学的示范 和统计分析方法，最重要的是，使用真实的数据的实践经验。这些内容和 格式不仅适合于鼓励教育和经验丰富的研究人员的合作， 也是一个非常有效的学习环境，研究生，博士后研究员，和初级 教师。会议主题为拟议的五年续约期是：1）认知老化， 人口统计学上多样化的人群，2），协调，联系和等同认知测量，3） 缺失数据、选择和定量偏倚分析，4）认知储备/弹性，5）分层 贝叶斯项目反应理论建模，以解决纵向数据的挑战。将有一次强 重点是围绕对真实的数据进行科学分析而组织的工作组，我们计划传播 通过传统学术渠道（如提交手稿） 供同行评审的科学期刊使用）以及通过年度科学会议上的专题讨论会。

PROJECT SUMMARY ABSTRACT The rapid increase in the older segment of the population has stimulated intense scientific interest in normal and pathological cognitive functioning in older adults. The increasing prevalence with advancing age of debilitating diseases like Alzheimer's disease has led to a need for clinical and research methods for measurement of effects of these diseases, and cognitive tests play a major role in detecting, diagnosing and monitoring disease status and progression. Increasing demographic diversity creates special challenges for accurate measurement of cognition. Most cognitive tests that are in clinical and research use were developed using psychometric methods from the first half of the 20th century. There have been substantial advances in measurement theory and methodology, notably item response theory (IRT) and associated latent variable modeling methods, that could have an important impact on the measurement of cognition. There have been parallel advances in statistical methodology for modeling longitudinal cognitive trajectories and identifying variables that positively and negatively impact these important outcomes. This conference series is designed to promote the application of modern psychometric and statistical methods in research on cognitive aging. Specific goals are: 1) to expose developing and established researchers in cognitive aging to modern psychometric and statistical modeling techniques, 2) to expose experts in psychometric theory and statistics to the practical and theoretical concerns of cognitive aging research, and 3) encourage collaborations of researchers, psychometricians, and statisticians during these conferences. We have conducted nine successful annual conferences since initial funding of this grant in 2008 and have a 10th planned for September, 2017. This series has generated 59 collaborative publications to date. This experience has helped to shape our plans for the next generation of conferences. The format of the conferences will include didactic presentations by experts in cognitive aging and applied psychometric theory, demonstrations of psychometric and statistical analytic methods, and most importantly, hands-on experience using real data. This content and format is not only appropriate for encouraging education and collaboration of seasoned researchers but has also been an extremely effective learning environment for graduate students, postdoctoral fellows, and junior faculty. Conference themes for the proposed five-year renewal period are: 1) Cognitive aging in demographically diverse populations, 2), Harmonization, linking and equating cognitive measurements, 3) Missing data, selection, and quantitative bias analysis, 4) Cognitive reserve/resilience, and 5) Hierarchical Bayesian item response theory modeling to address challenges in longitudinal data. There will be a heavy emphasis on workgroups organized around scientific analyses of real data, and we plan to disseminate the information resulting from these workshops in both traditional academic outlets (e.g. submission of manuscripts for peer reviewed scientific journals) and through symposia at annual scientific conferences.
