Alternate Title

MIDUS 2 Milwaukee

Summary

As a refinement to Midlife in the United States (MIDUS 2), 2004-2006 (ICPSR 4652), a sample of African Americans from Milwaukee was included to examine health issues in minority populations. Areas of the city of Milwaukee, Wisconsin, were stratified according to the proportion of the population that were African American. Those areas with high concentrations were sampled at higher rates than areas with lower concentrations. Area probability sampling methods were used along with population counts from the 2000 United States Census 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 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 1 and 2 samples. After successful completion of the Project 1 survey, some participants were eligible to participate in other MIDUS projects (2 through 5). Survey data was collected for 592 individuals.

Study Purpose

A specific aim of the MIDUS 2 was to recruit a new city-specific oversample of African Americans to participate in a field interview and questionnaire that paralleled the main sample instruments. Milwaukee was chosen in hopes of recruiting many of these respondents to the biological and neuroscience assessments.

The goal of this project was to complete interviews with 400 African Americans between 35 and 85 years of age. All respondents self-identified as black during the in-person screening process.

Study Design

All respondents were invited to participate in a phone interview of approximately 30 minutes in length and to complete 2 self-administered questionnaires (SAQs), each of approximately 45 pages in length. In addition, the twin subsample was administered a short screening survey to assess zygosity and other twin-specific information.

Sample

The sampling design was a stratified area probability sample of households in Milwaukee County, Wisconsin. The sampling frame included Census tracts in which at least 40 percent of the population was African American. The Census blocks were stratified by income, with roughly half coming from tracts in which the median household income was $40,000 or greater, and the rest coming from tracts in which the median household income was below $40,000.

Of the 7,108 participants in MIDUS 1, 4,963 were successfully contacted to participate in another phone interview of about 30 minutes in length. The average longitudinal follow-up interval was approximately 9 years and ranged from 7.8 to 10.4 years.

Response Rates

The overall response rate for the in-person interview was 70.7 percent. The overall SAQ response rate was 67.2 percent. The phone survey administration of the Telephone Assisted Cognitive Testing (TACT) had an overall response rate of 51.8 percent. Full discussion of the response rates for all of these portions of the MIDUS 2 Project 1 Milwaukee oversample are reported in the response rates section of Appendix A.
