Midlife in the United States (MIDUS 3), 2013-2014 (ICPSR 36346)
In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of over 7,000 Americans aged 25 to 74 [ICPSR 2760]. The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health. The study was innovative for its broad scientific scope, its diverse samples (which included siblings of the main sample respondents and a national sample of twin pairs), and its creative use of in-depth assessments in key areas (e.g. daily diary of stressful experiences [ICPSR 3725] and cognitive functioning [ICPSR 3596]) on a subset of participants. A detailed description of the study and findings generated by it are available at: http://www.midus.wisc.edu
With support from the National Institute on Aging, a follow-up of the original Midlife Development in the United States (MIDUS) sample was conducted in 2004 (MIDUS 2 [ICPSR 4652]). The daily stress and cognitive functioning projects were repeated and expanded at MIDUS 2; in addition the protocol was expanded to include biomarkers and neuroscience.
In 2013 a third wave (MIDUS 3) of survey data was collected on longitudinal participants. Data collection for this follow-up wave largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas such as economic recession experiences. Cognitive functioning data were also collected at the same time, while data collection for the daily diary, biomarker, and neuroscience projects commenced in 2017.
MIDUS also maintains a Colectica portal, which allows users to interact with variables across waves and create customized subsets. Registration is required.
Tsogolo La Thanzi (TLT): Migration Autopsy Data, Malawi, 2009-2012 [Healthy Futures] (ICPSR 37190)
The Tsogolo La Thanzi (TLT): Migration Autopsy collection contains data collected as part of the Tsogolo la Thanzi (TLT) Study. TLT is a longitudinal study in Balaka, Malawi designed to examine how young people navigate reproduction in an AIDS epidemic. Tsogolo la Thanzi means "Healthy Futures" in Chichewa, Malawi's most widely spoken language. New data is being collected to develop better understandings of the reproductive goals and behavior of young adults in Malawi -- the first cohort to never have experienced life without AIDS. To understand these patterns of family formation in a rapidly changing setting, TLT used the following approach: an intensive longitudinal design where respondents are interviewed every fourth months at TLT's centralized research center.
The Migration Autopsy collection contains many TLT respondents whom moved away during the study period. In order to both carefully track attrition and gather valuable information about migration, TLT performed a migration autopsy on study participants who migrated from the study area during the course of the 8-wave observation period. Data collection began in April of 2009 and was completed in December of 2012. To assess changes on a longer time-horizon, a follow-up survey we refer to as Tsogolo la Thanzi 2 (TLT-2) was fielded between June and August of 2016.
