Midlife in the United States: Core Sample Mortality Data, 1995-2020

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=2,124) from the Core National and Milwaukee samples as of December 2020.

1995年至1996年间，麦克阿瑟中年研究网络对美国25至74岁超过7,000名美国人进行了全国性调查（ICPSR 2760）。该研究的宗旨在于探究行为、心理和社会因素在理解年龄相关差异对身心健康影响中所扮演的角色。在老年研究院的支持下，对原初的美国中年发展研究（MIDUS）样本进行了首次跟踪调查，该调查于2004年进行（MIDUS 2）。在MIDUS 2中，日常压力和认知功能项目得以重复实施；此外，研究方案得到扩展，纳入了生物标志物和神经科学领域。2005年，为了研究少数族裔群体的健康问题，来自密尔沃基的592名非裔美国人样本被添加至MIDUS。2013年，对纵向参与者进行了第三次调查波（MIDUS 3）。此跟踪调查波的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报告问卷），并在选定领域增加了额外问题（例如，经济衰退体验、乐观与应对策略、压力性生活事件以及照护）。第三次认知功能数据波和第二次密尔沃基样本数据波也得以收集。日常日记、生物标志物和神经科学的数据收集仍在进行中。截至2020年12月，该数据集包含了核心国家样本和密尔沃基样本中所有已知的MIDUS死亡者（N=2,124）。
