In 2013, the Midlife in the United States (MIDUS) National Study of Health and Well-Being started its third wave of longitudinal data collection, contacting nearly 5,000 adults between the ages of 45 and 95 who had been MIDUS participants for nearly 20 years. The primary objective of the MIDUS study was to identify the major biomedical, psychological, and social factors that allow some people to achieve good health, psychological well-being, and social responsibility during the journey through middle life on into the later years. MIDUS 3 included additional questions about the 2008 recession to investigate its effect on health and well-being. MIDUS 3 protocols included a 45-minute telephone interview, a 100+ page mail questionnaire, and a 25-minute cognitive interview via telephone.
In 2011, the UWSC fielded the MIDUS Refresher to replenish the MIDUS longitudinal sample. The MIDUS Refresher used a multi-frame sample design, comprised of age-stratified RDD, cell and age-targeted list sample, to recruit 3500 new participants from across the nation, aged 25 to 75, into the study. The MIDUS Refresher protocols, similar to MIDUS 3, included a 45-minute telephone interview, a 100+ page mail questionnaire, and a 25-minute cognitive interview via telephone. The MIDUS Refresher included a random oversample of 500 African American participants conducted in Milwaukee, Wisconsin, with protocols that included a 2-hour in-person interview, a 50 page questionnaire, and a 25-minute cognitive interview.
