Midlife in the United States (MIDUS 3): Daily Diary Project, 2017-2019

The National Study of Daily Experiences (NSDE) is one of the in-depth studies that are part of the Midlife in the United States (MIDUS) longitudinal study of health and well-being. Known within the MIDUS study as the Daily Diary Project (2), the purpose of the NSDE is to examine the day-to-day lives, particularly the daily stressful experiences, of a subsample of MIDUS respondents. The primary aims of the MIDUS 3 Daily Diary project were to: (1) describe how the links between multiple aspects of daily stressors (e.g., frequency, content, severity) and daily physical and emotional well-being change over ten years during adulthood; (2) examine how sociodemographic factors and personality characteristics influence change in both exposure to as well as changes in physical and emotional reactivity to daily stressors; (3) investigate how exposure and reactivity to daily stressors correlate with physiological indicators of physical health and predict changes in global health reports; and (4) explore the relative genetic and environmental influences mediating change in exposure and physical and emotional reactivity to daily stressors throughout adulthood. During 2017-2019, the Daily Diary project collected data on a subsample of the MIDUS 3 survey sample, including cases from the MIDUS Milwaukee sample. A total of 1,236 respondents completed Daily Diary interviews. A subset of these respondents provided 4-days worth of saliva samples that provided data on cortisol and alpha amylase.

每日体验全国调查（National Study of Daily Experiences, NSDE）是隶属于美国中年健康与福祉纵向研究（Midlife in the United States, MIDUS）的深度研究项目之一。该项目在MIDUS研究框架内被称为日记追踪项目（Daily Diary Project，标注(2)），其核心宗旨为探究MIDUS受访者子样本的日常生活状态，尤其是日常应激体验。MIDUS第三轮日记追踪项目的主要研究目标如下：（1）阐释成年期十年间，日常应激源的多维度特征（如发生频率、内容、严重程度）与每日躯体及情绪福祉之间的关联如何随时间演变；（2）探究社会人口学因素与人格特征如何影响日常应激源暴露水平的变化，以及个体对应激源的躯体与情绪反应性的变化；（3）研究日常应激源的暴露水平与反应性如何与躯体健康的生理指标相关联，并预测整体健康自评报告的变化；（4）探索遗传与环境因素在成年期内如何介导日常应激源暴露水平，以及个体对应激源的躯体与情绪反应性的变化。2017年至2019年期间，该日记追踪项目针对MIDUS第三轮调查的子样本（含MIDUS密尔沃基子样本）收集了相关数据，共计1236名受访者完成了日记访谈。其中部分受访者提供了为期4天的唾液样本，用于获取皮质醇与α-淀粉酶的相关检测数据。
