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.

With support from the National Institute on Aging, an initial follow-up of the original Midlife Development in the United States (MIDUS) samples was conducted in 2004 (MIDUS 2). The daily stress and cognitive functioning projects were repeated 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 (e.g., economic recession experiences, optimism and coping, stressful life events, and caregiving). A third wave of cognitive functioning data were also collected. Demographic and background information includes gender, age, education, marital status, income and household composition.

Geographic Coverage:    United States

Time Period:   

  • 2013-05--2014-11

Date of Collection:   

  • 2013-05--2014-11

Unit of Observation:    individual, household

Universe:    The noninstitutionalized, English-speaking population of the United States.

Data Type(s):    survey data

Data Collection Notes:

The variable M2ID is the linking variable for the three datasets in this collection. The data in this collection can also be linked to all MIDUS data sets using the variable M2ID, including wave 1 (ICPSR 2760) and wave 2 (ICPSR 4652).

The Original P.I. Documentation found in this collection refers to the MIDUS Refresher data set. Please note that the data and corresponding documentation for this data set have not been deposited to ICPSR at this time.

Additional information about the Midlife Development in the United States study can be found at the MIDUS Web site.


Sample:    All respondents who completed the M2 phone interview were eligible to participate in the M3 survey.

Time Method:    Longitudinal

Weight:    The data are not weighted. Since M3 was the third wave of a longitudinal survey, there was no sampling and so no sampling weights were created. Post-stratification weights for M3 (adjusted to population parameters) will be forthcoming.

Mode of Data Collection:    computer-assisted telephone interview (CATI), cognitive assessment test, mail questionnaire

Description of Variables:   

The Aggregate Data set contains 2575 variables and 3294 cases. This data set includes information about the following types of variables: recession experience, health, education, occupation, marital status, household roster, children, caregiving, living arrangements, race and ethnicity and life satisfaction.

The Mortality Data set contains 9 variables and 1299 cases. This data set includes the updated decedent status of MIDUS and Milwaukee participants as of October 2015.

The Disposition Codes data set contains 6 variables and 7108 cases. This data set contains final disposition codes for all 7,108 individuals who participated in the M1 baseline survey.

Response Rates:    77 percent of living longitudinal participants completed the M3 phone survey. Details of fielding and final disposition codes can be found in the Field Report.

Presence of Common Scales:    For information regarding scales, please refer to the Psychosocial Constructs and Composite Variables.

Extent of Processing:   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:

  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.

Version History:

  • 2016-03-10 The MIDUS 3 Readme documentation has been updated.
  • 2016-03-07 The documents that were previously combined to create the User Guide have been filtered into the Pyschsocial Constructs and Composite Variables and the Naming and Coding Conventions documents. The documents combined to create the questionnaire documentation have been separated into the MIDUS 3 Telephone Interview and the MIDUS 3 Self-Administered Questionnaire (SAQ).
