PROJECT SUMMARY This five-year plan for a MOSAIC K99/R00 Postdoctoral Career Transition Award will equip Dr. Erica O’Brien with essential knowledge and skills to help launch her career as an independent scientist in health- focused aging research. This qualified candidate seeks to focus her research program on understanding the psycho-social and social cognitive determinants, multi-factorial pathways, and temporal dynamics underlying lifelong engagement in health-promoting behaviors and activities. The career development plan involves scientific training at Pennsylvania State University’s College of Health and Human Development under the mentorship of world-renowned experts in ecological momentary assessments, physical activity, aging/adult development, and health behavior research. The proposed training will supplement Dr. O’Brien’s existing background in studying age-related differences in cognitive engagement and in using diary designs with a foundation in intensive longitudinal methods and technologies as well as in health behavior research. Physical activity (PA) serves as an important behavioral pathway to delayed functional decline, disease, and mortality as well as to improved quality of life and psychological well-being in older age. Yet, many people do not obtain the recommended levels of PA, with insufficient PA being more likely in older adults. Existing studies increasingly indicate that people who believe that low PA reflects an expected and inevitable part of the aging process report lower levels of PA engagement, but the pathways explaining this relationship are unclear. Whereas theories of aging suggest that negative self-views of aging (NS-VOA) adopted earlier in life become internalized and self-fulling later in life, health behavior theories emphasize the lack of motivation to engage in PA and poor self-regulation of PA behavior as driving forces. Guided by these ideas, the proposed research uses an intensive within-person approach to characterize the relationship and underlying mechanisms between PA and NS-VOA as they unfold in daily life. K99 Years 1 and 2 will use existing data to address Aims 1 and 2. Aim 1 will characterize the extent of within-person variation in NS-VOA, testing whether NS-VOA vary significantly on four timescales: years, weeks, days, and moments (i.e., within-days). Aim 2 will examine the association between NS-VOA and PA on daily and momentary timescales. It is hypothesized that PA engagement will be lower on occasions when NS-VOA are higher than usual, with stronger relationships for higher (vs. lower) intensity PA and when device-based (vs. self- reported) PA are used. Aims 1 and 2 are novel, within-person assessment contexts important for understanding fast-acting relationships and underlying mechanisms. R00 Year 3 will collect and analyze new data for Aim 3 to test whether NS-VOA act through motivation and self-regulation factors to influence PA on daily and momentary timescales. This work will inform preparation and submission of an R-grant (R00 Years 4 and 5) that focuses on prevention and intervention to increase older adults’ PA at key times when NS-VOA may impair PA engagement.

项目概要 MOSAIC K99/R00 博士后职业转型奖的五年计划将为 Erica 博士提供装备 奥布莱恩拥有必要的知识和技能，可以帮助她开启健康领域独立科学家的职业生涯—— 重点关注老龄化研究。这位合格的候选人力求将她的研究计划集中在理解 心理社会和社会认知决定因素、多因素途径以及潜在的时间动态 终生参与促进健康的行为和活动。职业发展计划包括 在宾夕法尼亚州立大学健康与人类发展学院接受科学培训 生态瞬时评估、身体活动、衰老/成人领域世界知名专家的指导 发展和健康行为研究。拟议的培训将补充奥布莱恩博士现有的培训 研究与年龄相关的认知参与差异以及使用日记设计的背景 强化纵向方法和技术以及健康行为研究的基础。 体力活动 (PA) 是延迟性功能衰退、疾病、 和死亡率以及改善老年生活质量和心理健康。然而，很多人 未获得推荐的 PA 水平，老年人更可能出现 PA 不足的情况。现存的 越来越多的研究表明，那些相信低 PA 反映了预期和不可避免的部分的人 衰老过程报告 PA 参与水平较低，但解释这种关系的途径尚不清楚。 然而，衰老理论表明，在生命早期采取的对衰老的消极自我观（NS-VOA）会变得越来越重要。 健康行为理论强调，在以后的生活中内化和自我实现，缺乏参与的动力 PA和不良的自我调节成为PA行为的驱动力。在这些想法的指导下，拟议的研究 使用密集的内部方法来描述之间的关系和潜在机制 PA 和 NS-VOA 在日常生活中的表现。 K99 第 1 年和第 2 年将使用现有数据来实现目标 1 和 2。目标 1 将描述 NS-VOA 的人内差异，测试 NS-VOA 在四个时间尺度上是否显着变化：年、周、 天和时刻（即几天之内）。目标 2 将检查 NS-VOA 和 PA 之间的关联性 瞬时时间尺度。据推测，当 NS-VOA 关闭时，公共广播的参与度会降低。 高于平常，对于较高（与较低）强度 PA 以及基于设备（与自我）的关系更强 报道）使用PA。目标 1 和 2 是新颖的内部评估环境，对于理解很重要 快速反应的关系和基本机制。 R00 第 3 年将收集和分析目标 3 的新数据 测试 NS-VOA 是否通过动机和自我调节因素来影响日常和瞬间的 PA 时间尺度。这项工作将为 R 拨款（R00 第 4 和第 5 年）的准备和提交提供信息，该拨款的重点是 当 NS-VOA 可能损害 PA 参与的关键时刻，进行预防和干预，以提高老年人的 PA 参与度。
