2018-06-07 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Checked for undocumented or out-of-range codes.
Summary View help for Summary
These data are being released in BETA version to facilitate early access to the study for research purposes. This collection has not been fully processed by NACDA or ICPSR at this time; the original materials provided by the principal investigator were minimally processed and converted to other file types for ease of use. As the study is further processed and given enhanced features by ICPSR, users will be able to access the updated versions of the study. Please report any data errors or problems to user support and we will work with you to resolve any data related issues.
Data in this collection are related to MIDUS 3 [ICPSR 36346]. Data collection for the MIDUS 3 largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas (e.g., economic recession experiences, optimism and coping, stressful life events, and caregiving).
In 2013-2014, a second wave of cognitive assessments (MIDUS 3) were carried out on individuals who had recently completed the MIDUS 3 phone survey [ICPSR 36436]. This assessment, known as the Brief Test of Adult Cognition via Telephone (BTACT), was carried out approximately 9 years after the first wave of cognitive data collection was completed in 2004-2005. MIDUS 3 BTACT data were collected from 2,693 MIDUS 3 participants. Further, a second wave of cognitive assessments were also carried out on respondents to the MIDUS Milwaukee Wave 2 survey that was conducted in 2016-2017. BTACT data were collected from 329 Milwaukee respondents. This M3 BTACT dataset contains a total of 3,023 respondents.
The dataset includes 244 variables and 3,023 cases. Demographic variables in this collection include sex and age.

Study Purpose View help for Study Purpose
The overarching objective of MIDUS is to investigate linkages between sociodemographic, psychosocial, and biological variables to account for later life profiles of morbidity and mortality.
The purpose of the Cognitive Project was to determine how cognition is related to overall mental and physical health. Specific goals were: (1) to characterize the nature and range of midlife cognitive performance, relative to those younger and older, across multiple domains in a nationally representative sample (MIDUS); and (2) to examine the relationship between biopsychosocial factors (e.g. SES, health status, health-promoting behaviors, metabolic and cardiovascular biomarkers, depression, personality, control beliefs, stressful life events) and individual difference in cognitive functioning. The development of a cognitive battery provided an opportunity to examine the cognitive performance of young, middle-aged and older adults from a wide range of education levels in a large-scale, national sample.
Study Design View help for Study Design
The BTACT is the first comprehensive cognitive battery, including measures of speed and reaction time, to be administered by telephone to a national sample across the adult years and into later life. It includes seven subtests: word list recall immediate, word list recall delayed, backward digit span, number series, counting backward speed task, category fluency, and an attention switching reaction time task. Given the nature of the MIDUS sample, the cognitive project provides a rich data set to examine individual differences in cognitive functioning and changes therein over 9 years with a diverse sample in terms of age, sex, socioeconomic status (income, education) and geographical region. For more information on the BTACT instrument, please visit the Lifespan Lab Website and the publication by Lachman, Margie E. et al.
