Midlife in the United States (MIDUS Refresher): Daily Diary Project, 2012-2014

These data are being released in BETA version to facilitate early access to the study for research purposes. This collection has not been fully processed by NACDA or ICPSR at this time; the original materials provided by the principal investigator were minimally processed and converted to other file types for ease of use. As the study is further processed and given enhanced features by ICPSR, users will be able to access the updated versions of the study. Please report any data errors or problems to user support and we will work with you to resolve any data related issues. The MIDUS Refresher Daily Diary Project (aka National Study of Daily Experiences or NSDE) contains data from 782 respondents. The purpose of the Daily Stress Project was to examine how sociodemographic factors, health status, personality characteristics, and genetic endowment modify patterns of change in exposure to day-to-day life stressors as well as physical and emotional reactivity to these stressors. The primary aims were: To 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; To 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; To investigate how exposure and reactivity to daily stressors correlate with physiological indicators of physical health and predict changes in global health reports; and To explore the relative genetic and environmental influences mediating change in exposure and physical and emotional reactivity to daily stressors throughout adulthood. The Daily Diary study is comprised of a subsample of the MIDUS (Midlife in the United States) Refresher, a national survey of nearly 3,600 Americans (aged 25 to 75) conducted during 2011-2014. The MIDUS Refresher survey was designed to replenish the original MIDUS 1 baseline cohort and allow the examination of period effects on health (mental and physical) related to the economic recession by comparing the pre-recession MIDUS 1 sample with the post-recession MIDUS Refresher sample. Guiding hypotheses, at the most general level, were that behavioral and psychosocial factors are consequential for health (physical and mental). Demographic variables in this collection include sex and age.

本数据集以Beta版本形式发布，旨在便于研究目的的早期访问。截至目前，该数据集尚未由NACDA或ICPSR进行全面处理；由主要研究人员提供的原始材料仅经过最小化处理，并转换为其他文件类型以方便使用。随着ICPSR对研究的进一步处理和功能的增强，用户将能够访问研究更新的版本。请向用户支持报告任何数据错误或问题，我们将与您合作解决任何数据相关的问题。MIDUS每日日记项目（又称国家日常体验研究或NSDE）包含782名受访者的数据。每日压力项目的目的是研究社会人口统计学因素、健康状况、人格特征和遗传禀赋如何改变日常生活压力源暴露的动态模式，以及对这些压力源的生理和情绪反应。主要目标包括：描述日常压力源的多方面属性（如频率、内容、严重程度）与日常生理和情绪福祉之间的联系如何在成年后的十年中发生变化；考察社会人口统计学因素和人格特征如何影响对日常压力源的暴露以及生理和情绪反应的变化；探究日常压力源的暴露和反应与生理健康指标的相关性，并预测全球健康报告的变化；以及探索在成年期间调节对日常压力源暴露和生理、情绪反应变化的相对遗传和环境影响因素。每日日记研究由MIDUS（美国中年）更新样本的子样本组成，这是一项针对近3600名美国人（年龄在25至75岁之间）于2011-2014年间进行的全国性调查。MIDUS更新调查旨在补充原始MIDUS 1基线队列，并允许通过比较经济衰退前后的MIDUS 1样本与MIDUS Refresher样本，来研究经济衰退对（精神和生理）健康相关的时期效应。在最一般的层面上，指导假设是行为和心理社会因素对健康（生理和心理健康）具有重要影响。本数据集中的人口统计学变量包括性别和年龄。
