PROJECT SUMMARY Social wellbeing and cognitive health are two pillars of successful aging, and they are interrelated. Three decades of research have consistently shown that social isolation is associated with declines in cognitive functioning. Although existing literature has explored the individual-level risk and protective factors, researchers' attention has been less paid to the extent to which physical and social characteristics of the living environment affect social isolation and cognitive health. The Ecological Theory of Aging (ETA) posits environmental factors have significant influences on health and social wellbeing. Negative physical characteristics of the environment were hypothesized to be related to increased social isolation and cognitive decline longitudinally. An increasing amount of research investigated the association between ICT use and social isolation, yet whether ICT use would interact with the effect of environmental factors on the risk of social isolation has not yet been empirically tested. Besides, the influence of ICT use on cognitive health has not been well understood. Promoting social interaction using technology-based approaches have the potential to alleviate social isolation among older people and prevent cognitive decline. The proposed dissertation work (F99) will examine the effect of physical and social environments of living on social isolation and cognitive health. The effects of ICT use will be investigated within living contexts. Multi-level modeling and structural equation modeling methods will be employed to conduct secondary data analysis using data from the National Health & Aging Trend Study (NHATS) wave 5 to 9. The postdoctoral stage (K00) is guided by the overarching aim of building knowledge on the behavioral and contextual pathways that could explain the association between social isolation and cognitive decline and developing a community-based behavioral health intervention. At the K00 phase, the PI will increase understanding of the social isolation and cognitive health research landscape by conducting a systematic review. Longitudinal data from the ongoing Internet-based Conversational Engagement Clinical Trial (I-CONECT) will be analyzed to examine the association between social isolation and change in neuropsychological outcomes. The PI will utilize the longitudinal data collected with the Collaborative Aging Research Using Technology (CART) platform to investigate the relationships between daily activities, social engagement, and the cognitive health of older participants. Knowledge to be built at F99 and K00 stages will be synthesized to inform the participatory co-design of a technology-facilitated intervention program for social isolation and cognitive decline. The proposed research will produce knowledge on the influence of environmental factors on social isolation and cognitive health, and achieve the PI’s long-term professional goal of developing behavioral health intervention to address social isolation and prevent the onset of Alzheimer's Disease and Related Dementias.

项目概要 社会福祉和认知健康是成功老龄化的两大支柱，并且它们是相互关联的三者。 数十年的研究一致表明，社会孤立与认知能力下降有关 尽管现有文献已经探讨了个体层面的风险和保护因素，但研究人员的功能。 人们较少关注生活环境的物理和社会特征在多大程度上 影响社会孤立和认知健康的生态衰老理论（ETA）假定环境因素。 环境的负面物理特征对健康和社会福祉具有重大影响。 纵向增加与社会孤立增加和认知能力下降有关。 大量研究调查了信息通信技术的使用与社会孤立之间的关联，但信息通信技术的使用是否 环境因素对社会孤立风险影响的相互作用尚未得到实证研究 此外，信息通信技术的使用对认知健康的影响尚未得到充分了解。 使用基于技术的方法进行互动有可能缓解老年人之间的社会孤立 拟议的论文工作（F99）将研究身体的影响。 以及生活的社会环境对社会隔离和认知健康的影响。 将在生活环境中研究多层次建模和结构方程建模方法。 受雇使用国家健康与老龄化趋势研究 (NHATS) 的数据进行二次数据分析 第 5 波至第 9 波。博士后阶段 (K00) 的总体目标是构建关于 行为和情境路径可以解释社会孤立和 下降并制定基于社区的行为健康干预措施 在 K00 阶段，PI 将增加。 通过进行系统回顾来了解社会隔离和认知健康研究领域。 正在进行的基于互联网的对话参与临床试验 (I-CONECT) 的纵向数据将 进行分析以检查社会孤立与神经心理学结果变化之间的关联。 PI 将利用通过协作老化研究技术 (CART) 收集的纵向数据 调查日常活动、社交参与和认知健康之间关系的平台 将综合 F99 和 K00 阶段的年长参与者知识，为参与者提供信息。 共同设计一项技术辅助的干预计划，以应对社会孤立和认知能力下降。 研究将产生关于环境因素对社会孤立和认知的影响的知识 健康，并实现 PI 制定行为健康干预措施的长期专业目标，以解决 社会隔离和预防阿尔茨海默病和相关痴呆症的发作。
