背景:每日压力源与认知能力下降和心脏病风险增加有关,抑郁症,和其他使中年成年人衰弱的慢性疾病。日常压力源往往发生在家里或工作中,在城市和农村环境中更为频繁。相反,花时间在公园或森林等自然环境中,甚至在实验室环境中查看以自然为主题的图像,与较低水平的感知压力相关,并被假设为强大的压力缓冲,“即使在离开自然环境后,也能减少感知到的压力。然而,许多关于日常压力的研究没有捕获环境背景,而是依赖于一天结束时的回忆,而不是即时数据捕获.有了新技术,这些限制可以解决,以提高日常压力经验的知识。
目的:我们建议使用我们新颖的定制的可变环境中的压力报告(STRIVE)生态瞬时评估手机应用程序来测量自由生活条件下中年成年人的日常压力体验。使用我们的应用程序实时捕获数据将使我们能够确定(1)中年成年人的日常压力发生的地点和时间,(2)中年成年人的日常压力源是否与建筑和自然环境的某些元素有关,和(3)日常压力的生态瞬时评估测量与流行的每日压力事件测量工具的修改版本相似和不同,该工具捕获了一天结束的压力报告(在美国的Midlife[MIDUS]调查中使用)。
方法:我们将招募150名居住在大印第安纳波利斯的中年成年人,印第安纳州,在这项为期3周的滚动研究中。由于以前发现少数群体和低收入地区的人承受更大的压力,我们将使用分层抽样来确保我们研究样本的一半由代表性不足的少数民族组成(例如,黑色,美洲印第安人,西班牙裔,或本地太平洋岛民),大约三分之一的样本落在低点,middle-,和高收入阶层。
结果:该项目由国家老龄化研究所于2022年12月至2024年11月资助。参与者注册于2023年8月开始,预计将于2024年7月完成。将对数据进行时空分析,以确定中年成年人的压力发生地点和时间。将对压力环境的图片进行定性分析,以确定压力环境的常见元素。STRIVE应用程序收集的数据将与压力事件数据的回顾性每日清单进行比较。
结论:完成这项研究将扩大我们对中年成年人在自由生活条件下的压力体验的理解,并为数据驱动的个人和社区干预设计铺平道路,以促进中年成年人的健康和福祉。

BACKGROUND: Daily stressors are associated with cognitive decline and increased risk of heart disease, depression, and other debilitating chronic illnesses in midlife adults. Daily stressors tend to occur at home or at work and are more frequent in urban versus rural settings. Conversely, spending time in natural environments such as parks or forests, or even viewing nature-themed images in a lab setting, is associated with lower levels of perceived stress and is hypothesized to be a strong stress \"buffer,\" reducing perceived stress even after leaving the natural setting. However, many studies of daily stress have not captured environmental contexts and relied on end-of-day recall instead of in-the-moment data capture. With new technology, these limitations can be addressed to enhance knowledge of the daily stress experience.
OBJECTIVE: We propose to use our novel custom-built Stress
Reports in Variable Environments (STRIVE) ecological momentary assessment mobile phone app to measure the experience of daily stress of midlife adults in free-living conditions. Using our app to capture data in real time will allow us to determine (1) where and when daily stress occurs for midlife adults, (2) whether midlife adults\' daily stressors are linked to certain elements of the built and natural environment, and (3) how ecological momentary assessment measurement of daily stress is similar to and different from a modified version of the popular Daily Inventory of Stressful Events measurement tool that captures end-of-day stress
reports (used in the Midlife in the United States [MIDUS] survey).
METHODS: We will enroll a total of 150 midlife adults living in greater Indianapolis, Indiana, in this study on a rolling basis for 3-week periods. As those in underrepresented minority groups and low-income areas have previously been found to experience greater levels of stress, we will use stratified sampling to ensure that half of our study sample is composed of underrepresented minorities (eg, Black, American Indian, Hispanic, or Native Pacific Islanders) and approximately one-third of our sample falls within low-, middle-, and high-income brackets.
RESULTS: This project is funded by the National Institute on Aging from December 2022 to November 2024. Participant enrollment began in August 2023 and is expected to finish in July 2024. Data will be spatiotemporally analyzed to determine where and when stress occurs for midlife adults. Pictures of stressful environments will be qualitatively analyzed to determine the common elements of stressful environments. Data collected by the STRIVE app will be compared with retrospective Daily Inventory of Stressful Events data.
CONCLUSIONS: Completing this study will expand our understanding of midlife adults\' experience of stress in free-living conditions and pave the way for data-driven individual and community-based intervention designs to promote health and well-being in midlife adults.
