Midlife in the United States Series (MIDUS)
MIDUS data were collected in 1995 - 1996 from a national sample of over 7,000 individuals aged 25 to 75 in the United States of America, aiming to investigate the role of behavioral, psychological, and social factors in accounting for age-related variations in health and well-being. Based on the success of MIDUS, the study was awarded a grant in 2002-2008 to carry out a longitudinal follow-up of MIDUS respondents. MIDUS 2 thus consisted of separate research projects, including Cognition, Daily Diary, Biomarker, and Neuroscience projects, each of which collected different information from sample respondents. The study was extended for a 3rd round of funding in 2011-2016, where data came from independent samples, known as the MIDUS Refresher. MIDUS 3 study included longitudinal follow-up of MIDUS samples from 2013 - 2015.
