Midlife in the United States (MIDUS Refresher 1): Milwaukee African American Sample, 2012-2013

In 2012-2013, the MIDUS Milwaukee Refresher study recruited a sample of 508 Milwaukee African American adults, aged 25 to 64, designed to replenish the Midlife Development in the United States (MIDUS 2): Milwaukee African American Sample, 2005-2006 (ICPSR 22840). This sample was also designed to increase the number of racial minorities included in the broader MIDUS study. The MIDUS Milwaukee Refresher survey employed the same assessments (demographic, psycho-social, and physical and mental health) as those assembled on the existing MIDUS sample, but with additional questions about the effect of the economic recession of 2008-09. A sample of African Americans from Milwaukee County, Wisconsin, was stratified by age, gender, and income. Area probability sampling methods were used to identify potential respondents. Field interviewers screened households to determine if they contained any African American adults. There was additional screening to achieve an appropriate age/gender distribution in a manner similar to what was done for the original MIDUS sample (Midlife in the United States (MIDUS 1), 1995-1996 [ICPSR 2760]). Milwaukee respondents were interviewed in their homes using a 2.5-hour Computer Assisted Personal Interview (CAPI) protocol and afterwards asked to complete a self-administered questionnaire (SAQ). All measures paralleled those used in the larger MIDUS samples. In addition to successful completion of the survey, participants were asked to complete a cognitive assessment by phone. Some respondents were eligible to participate in additional MIDUS projects: daily diary assessments, biomarker assessments, and neuroscience assessments.

2012-2013年间，MIDUS（美国中年发展研究）密尔沃基更新研究项目招募了508名年龄在25至64岁之间的密尔沃基非洲裔美国人，旨在补充2005-2006年间进行的美国中年发展研究（MIDUS 2）：密尔沃基非洲裔美国人样本（ICPSR 22840）。此样本的设立亦旨在扩大MIDUS研究项目中种族少数群体的代表性。MIDUS密尔沃基更新调查采用了与现有MIDUS样本相同的评估方法（包括人口统计、心理社会、生理和心理健康等），并额外增加了关于2008-2009年经济衰退影响的问题。来自威斯康星州密尔沃基县的非洲裔美国人样本按年龄、性别和收入进行了分层。采用区域概率抽样方法识别潜在受访者。实地访谈员对家庭进行筛选，以确定家庭中是否包含非洲裔成年人。为了实现与原始MIDUS样本（美国中年（MIDUS 1），1995-1996年[ICPSR 2760]）类似的目标年龄/性别分布，进行了额外的筛选。密尔沃基受访者在家中接受为期2.5小时的计算机辅助个人访谈（CAPI）并随后被要求完成一份自我管理问卷（SAQ）。所有测量指标都与更大规模的MIDUS样本保持一致。除了完成调查外，参与者还被要求通过电话完成一项认知评估。一些受访者有资格参与额外的MIDUS项目：日常日记评估、生物标志物评估和神经科学评估。
