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.

项目摘要 这项摩西K99/R00的五年计划将为Erica博士提供服务。 奥布莱恩（O'Brien 专注的衰老研究。这位合格的候选人试图将她的研究计划集中在理解 心理社会和社会认知决定者，多因素途径以及临时动态 终身参与促进健康的行为和活动。职业发展计划涉及 宾夕法尼亚州立大学健康与人类发展学院的科学培训 世界知名专家的生态瞬时评估，体育锻炼，衰老/成人的遗产 发展和健康行为研究。拟议的培训将补充奥布莱恩博士的现有 研究与年龄相关的认知参与和使用日记设计的背景 密集纵向方法和技术以及健康行为研究的基础。 体育活动（PA）是延迟功能下降，疾病， 和死亡率以及改善年龄段的生活质量和心理健康。但是，很多人 请勿获得建议的PA水平，而老年人的PA不足可能不足。现存的 研究越来越多地表明，那些认为低PA的人反映了预期和不可避免的一部分 衰老过程报告PA参与度较低，但是解释这种关系的途径尚不清楚。 衰老理论表明，衰老的负面自我观察（NS-VOA）在生活中采用了 在以后的生活中，内在化和自我实现，健康行为理论强调缺乏动力 PA和对PA行为作为驱动力的不良自我调节。在这些想法的指导下，拟议的研究 使用密集的内部方法来表征关系和基本机制 PA和NS-VOA在日常生活中展开。 K99年1年和2年将使用现有数据来解决目标1和2。AIM 1将表征 NS-VOA的人体内部变化，测试NS-VOA是否在四个时间尺度上有显着差异：年，几周， 几天和时刻（即末日）。 AIM 2将检查NS-VOA和PA之间的关联 暂时的时间尺度。假设NS-VOA的情况下，PA的参与度将较低 比平常更高，具有更高（与较低）强度PA的关系更强，并且基于设备的关系（与自我 报告了PA。目标1和2是新颖的人内评估环境，对于理解很重要 快速作用的关系和潜在的机制。 R00 3年级将收集和分析AIM 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PA对日常和暂时的影响 时间尺度。这项工作将为R-Grant（4年和5年）的准备和提交提供信息，该工作重点介绍 在NS-VOA可能会损害PA参与度的关键时间，预防和干预以增加老年人的PA。
