Midlife in the United States (MIDUS 3): Cognitive Project, 2013-2017

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. The study was innovative for its broad scientific scope, its diverse samples (which included siblings of the main sample respondents and a national sample of twin pairs), and its creative use of in-depth assessments in key areas (e.g. daily diary of stressful experiences [ICPSR 3725] and cognitive functioning [ICPSR 3596]) on a subset of participants. A detailed description of the study and findings generated by it are available at: http://www.midus.wisc.edu. With support from the National Institute on Aging, a follow-up of the original Midlife Development in the United States (MIDUS) sample was conducted in 2004 (MIDUS 2 [ICPSR 4652]). The daily stress and cognitive functioning projects were repeated and expanded at MIDUS 2; in addition the protocol was expanded to include biomarkers and neuroscience. 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 such as economic recession experiences. Cognitive functioning data were also collected at the same time, while data collection for the daily diary, biomarker, and neuroscience projects commenced in 2017. Data in this collection are related to MIDUS 3 [ICPSR 36346]. Data collection for the MIDUS 3 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). In 2013-2014, a second wave of cognitive assessments (Project 3) were carried out on individuals who had recently completed the MIDUS 3 phone survey (Project 1). This assessment, known as the Brief Test of Adult Cognition via Telephone (BTACT), was carried out approximately 9 years after the first wave of cognitive data collection was completed in 2004-2005. MIDUS 3 BTACT data were collected from 2,693 MIDUS 3 participants. Further, a second wave of cognitive assessments were also carried out on respondents to the MIDUS Milwaukee Wave 2 survey that was conducted in 2016-2017. BTACT data were collected from 330 Milwaukee respondents. Finally, BTACT data was collected in 2017 from another 268 respondents (called the Refielding sample) who did not complete this project during the M3 field period. This M3 BTACT dataset contains a total of 3,291 respondents. More details on the fielding of these cases can be found in the MIDUS field reports for the M3 survey [ICPSR 36346] and the Milwaukee 2 survey [ICPSR 37120]. The dataset includes 245 variables and 3,291 cases. Demographic variables in this collection include sex and age.

1995年至1996年间，麦克阿瑟中年研究网络对7,000多名25至74岁的美国公民进行了全国性调查[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的影响中的作用。该研究因广泛的科学视野、多样化的样本（包括主要样本受访者的兄弟姐妹及全国性双胞胎样本）以及其在关键领域（例如，压力体验的日常日记[ICPSR 3725]和认知功能[ICPSR 3596]）中对部分参与者的深入评估之创新性而著称。关于该研究及其产生的发现，详细信息可查阅：http://www.midus.wisc.edu。在国家老龄研究所的支持下，对最初的美国中年发展研究（MIDUS）样本进行了2004年的后续研究（MIDUS 2 [ICPSR 4652]）。在MIDUS 2中，日常压力和认知功能项目得到了重复和扩展；此外，研究方案也得到了扩展，纳入了生物标志物和神经科学。2013年，对纵向参与者进行了第三次调查波（MIDUS 3）。此后续调查波的数据收集在很大程度上重复了基线评估（例如，电话访谈和广泛的自我管理问卷），并在选定领域（例如，经济衰退经历）中增加了额外问题。同时收集了认知功能数据，而日常日记、生物标志物和神经科学项目的数据收集则始于2017年。该收集的数据与MIDUS 3 [ICPSR 36346]相关。MIDUS 3的数据收集在基线评估（例如，电话访谈和广泛的自我管理问卷）的基础上进行了大量重复，并在选定领域（例如，经济衰退经历、乐观与应对策略、压力性生活事件和照护）中增加了额外问题。2013-2014年，对最近完成MIDUS 3电话调查（项目1）的个人进行了第二次认知评估波（项目3）。这项评估被称为通过电话进行的成人认知简测（BTACT），在大约9年前，即2004-2005年第一次波次认知数据收集完成后进行。MIDUS 3 BTACT数据是从2,693名MIDUS 3参与者中收集的。此外，还对2016-2017年进行的MIDUS密尔沃基波2调查的受访者进行了第二次认知评估。BTACT数据是从330名密尔沃基受访者中收集的。最后，2017年，从268名（称为重新抽样样本）未在M3现场调查期间完成此项目的受访者中收集了BTACT数据。该M3 BTACT数据集包含总计3,291名受访者的数据。关于这些案例的实地调查的更多细节，可在M3调查的MIDUS实地报告中找到[ICPSR 36346]以及密尔沃基2调查[ICPSR 37120]。该数据集包括245个变量和3,291个案例。该收集中的人口统计学变量包括性别和年龄。
