Midlife in the United States (MIDUS 3): Milwaukee African American Sample, 2016-2017

In 2005, 592 African Americans from Milwaukee were added to the MIDUS sample to examine health issues in minority populations (for more details, see Midlife in the United States (MIDUS 2): Milwaukee African American Sample [ICPSR #22840]). Respondents were interviewed in their homes using a Computer Assisted Personal Interview (CAPI) survey protocol and asked to complete and return a Self-Administered Questionnaire (SAQ). Afterwards these individuals were eligible for participation in the same research protocol as the national MIDUS 2 sample, including cognitive, daily stress, biomarker, and neuroscience projects. With support from the National Institute on Aging, a second wave of survey data collection on the Milwaukee sample was begun in 2016. The survey consisted of a 2.5 hour CAPI interview followed by a 45-page mailed SAQ. CAPI survey data was collected for 389 individuals, realizing a 78 percent response rate, adjusted for mortality and other eligibility criteria. Data collection for this follow-up wave largely repeated baseline assessments, with additional questions in selected areas (e.g., economic recession experiences, childhood experience with race, etc.). Following successful completion of the CAPI and SAQ protocols, individuals were eligible for participation in cognitive, daily stress, biomarker, and neuroscience projects.

2005年，592名来自美国密尔沃基市的非裔美国人被纳入美国中年发展研究（Midlife in the United States, MIDUS）样本，以考察少数群体的健康议题（更多细节可参见《美国中年发展研究（MIDUS 2）：密尔沃基非裔美国人样本》[ICPSR 编号#22840]）。受访者在家中通过计算机辅助个人访谈（Computer Assisted Personal Interview, CAPI）流程接受访问，并被要求填写并寄回自填式问卷（Self-Administered Questionnaire, SAQ）。此后，该群体可与全国性MIDUS 2样本参与者一同参与同一套研究方案，涵盖认知、日常压力、生物标志物及神经科学相关研究项目。在美国国家衰老研究所（National Institute on Aging）的资助下，针对密尔沃基样本的第二轮调查数据收集工作于2016年启动。本次调查包含2.5小时的CAPI访谈，以及一份45页的邮寄式自填式问卷。最终共有389名受访者完成CAPI调查，经死亡率与其他入组标准调整后，应答率达78%。该追踪波次的数据收集工作大体重复了基线评估内容，并在部分领域增设了额外问题（如经济衰退经历、童年种族经历等）。在顺利完成CAPI与SAQ调查流程后，参与者同样有资格参与认知、日常压力、生物标志物及神经科学相关研究项目。
