DESCRIPTION (provided by applicant): In order to identify functional ability risk factors for adverse mobility outcomes among older drivers, a collaborative study was initiated in 1998 between the Maryland Motor Vehicle Administration (MVA), NHTSA, and the NIA-funded UAB Roybal Center for Research on Applied Gerontology. In this study, a large sample (N=2415) of older adults was evaluated with a brief battery of performance-based measures after completing license renewal at several MVA field sites. In addition, a sub-sample of these participants (N=1432) was followed for a period of up to ten years by telephone interview in order to monitor changes in their overall health and mobility. Through that study, a limited set of functional ability tests were found to be predictive of future crash involvement, and deemed useful by the Maryland MVA for further evaluation and potential implementation in the licensing process. In addition, these same variables were found to be predictive of general declines in mobility and loss of independence. The present research proposes 1) to continue to follow the 812 older adults remaining in the interview sample as they continue to age, 2) to establish a new, more representative, population-based sample of drivers (aged 70+) using the next generation of functional ability tests to determine whether earlier crash prediction relationships can be replicated, and 3) to evaluate a speed of processing cognitive training program in the context of the MVA as a means of facilitating and extending safe mobility. PUBLIC HEALTH RELEVANCE: Age-related changes in health, as well as physical, sensory, and cognitive function, frequently leave older persons more vulnerable to loss of mobility and increased risk of injuries due to falls or automobile crashes. The relationships between functional abilities and crash risk, demonstrated through this ongoing research project, have received wide attention as this and other societies struggle to develop new policies that balance the need for personal mobility and public safety in an aging population. Findings from the next phase of this study will have important implications for designing policies and programs to extend the safe mobility of older drivers, as well as evaluating the impact of enhancing cognitive function on a variety of other outcomes important to sustaining mobility, health, independence, and a satisfying quality of life.

描述（由申请人提供）：为了确定老年驱动因素不良行动能力结果的功能能力风险因素，1998年在马里兰州机动车管理（MVA），NHTSA和NIA资助的UAB UAB ROYBAL ROYBAL APPLICERIPED SERONTOLOGY研究中心进行了协作研究。在这项研究中，在几个MVA场地完成许可证续订后，通过短暂的基于绩效的措施对老年人进行了大量样本（n = 2415）。此外，通过电话访谈跟踪了这些参与者的子样本（n = 1432）长达十年，以监控其整体健康和流动性的变化。通过该研究，发现一组有限的功能能力测试可以预测未来的崩溃参与，并被马里兰州MVA认为有用，以进一步评估和在许可过程中的潜在实施。此外，发现这些相同的变量可以预测流动性和独立性丧失的总体下降。 The present research proposes 1) to continue to follow the 812 older adults remaining in the interview sample as they continue to age, 2) to establish a new, more representative, population-based sample of drivers (aged 70+) using the next generation of functional ability tests to determine whether earlier crash prediction relationships can be replicated, and 3) to evaluate a speed of processing cognitive training program in the context of the MVA as a means of facilitating and extending safe mobility. 公共卫生相关性：与年龄相关的健康以及身体，感觉和认知功能的变化，经常使老年人更容易受到移动丧失的影响，并因跌倒或汽车撞车而造成的伤害风险增加。通过这项正在进行的研究项目证明的功能能力与崩溃风险之间的关系受到了广泛关注，因为这个社会和其他社会都难以制定新的政策，以平衡老龄化人口中对个人流动性和公共安全的需求。这项研究的下一阶段的发现将对设计政策和计划具有重要意义，以扩大较老驱动力的安全性，并评估增强认知功能对对维持移动性，独立性，独立性和满足生活质量的其他各种结果的影响。
