Midlife in the United States: Core Sample Mortality Data, 2016

In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of over 7,000 Americans aged 25 to 74 [ICPSR 2760]. The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health. With support from the National Institute on Aging, an initial follow-up of the original Midlife Development in the United States (MIDUS) samples was conducted in 2004 (MIDUS 2). The daily stress and cognitive functioning projects were repeated at MIDUS 2; in addition the protocol was expanded to include biomarkers and neuroscience. In 2005, a baseline sample of 592 African Americans from Milwaukee was added to MIDUS to examine health issues in minority populations. In 2013 a third wave (MIDUS 3) of survey data was collected on longitudinal participants. Data collection for this follow-up wave largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas (e.g., economic recession experiences, optimism and coping, stressful life events, and caregiving). A third wave of cognitive functioning data and a second wave of the Milwaukee sample were also collected. Data collection for the daily diary, biomarkers, and neuroscience is ongoing. This dataset includes all known MIDUS decedents (N=1,511) from the Core National and Milwaukee samples as of December 2016.

于1995-1996年间，由麦克阿瑟中年研究网络对超过7,000名25至74岁的美国公民进行了全国性调查[ICPSR 2760]。本研究旨在探究行为、心理及社会因素在理解年龄相关差异对身心健康的影响中所扮演的角色。在国家老龄研究所的支持下，对原初的美国中年发展研究（MIDUS）样本进行了首次跟踪调查（MIDUS 2）于2004年实施。在MIDUS 2中，对日常压力和认知功能项目进行了重复研究；此外，研究方案得到了扩展，纳入了生物标志物和神经科学领域。2005年，为研究少数族裔群体的健康问题，MIDUS项目新增了来自密尔沃基的592名非裔美国人的基线样本。2013年，对纵向参与者收集了第三次调查数据（MIDUS 3）。此次数据收集主要重复了基线评估（例如，电话访谈和广泛的自我管理问卷），并在选定领域增加了相关问题（例如，经济衰退经历、乐观与应对策略、压力性生活事件以及照护）。此外，还收集了第三次认知功能数据和密尔沃基样本的第二波数据。日常日记、生物标志物和神经科学的数据收集仍在进行中。该数据集包含了截至2016年12月为止，来自核心国家样本和密尔沃基样本的所有已知的MIDUS去世者（N=1,511）。
