Midlife in the United States (MIDUS 1) National Study of Daily Experiences (NSDE), 1996-1997 (ICPSR 3725)
Released/updated on: 2023-01-25
Geographic coverage: United States
Time period: 1996-03-01--1997-03-01
The National Study of Daily Experiences (NSDE) is one of the in-depth studies that are part of the MacAuthur Foundation National Survey of Midlife in the United States (MIDUS). The purpose of the NSDE is to examine the day-to-day lives, particularly the daily stressful experiences, of a subsample of MIDUS respondents. Although previous daily diary research has advanced understanding of daily stress processes, there are important limitations in these studies that are addressed in the NSDE. First, previous studies in this area have relied on small and often unrepresentative samples that limit the ability to generalize findings. For this reason, the NSDE uses a large national sample of adults in the United States. Second, previous studies of individual differences in exposure and reactivity to daily events have typically examined only one source of variability, such as personality, to the exclusion of others. The NSDE corrects this problem by utilizing the data collected in the larger MIDUS survey on a wide array of sociodemographic and psychosocial variables to study the determinants of exposure and reactivity to daily stress. Third, previous studies have failed to investigate the role of genetics in both exposure and reactivity to daily stressors. The NSDE has a subsample of identical and fraternal same-sex twin pairs in order to explore this issue. The twins were selected if twin pairs had high self-reported certainty of zygosity, had completed the MIDUS interview and questionnaires, and had mailed in their cheek cell samples. A wide range of information was obtained using the daily telephone interview. Conducting interviews for an entire year provided information about seasonal variation in daily experiences. Respondents completed an average of 7.2 of the 8 interviews resulting in a total of 10,397 days of interviews. Data collection consisted of 40 separate "flights" of interviews with each flight representing the eight-day sequence of interviews from approximately 33 respondents. The entire interview was CATI programmed, which enabled researchers to incorporate skip patterns and open ended probe questions as well as to keypunch data during the interview, allowing data cleaning throughout the data collection. Demographic information includes gender and age.

Midlife in the United States (MIDUS 2), 2004-2006 (ICPSR 4652)
Released/updated on: 2021-09-15
Geographic coverage: United States
Time period: 2004-01-01--2006-01-01
In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of 7,108 Americans aged 25 to 74 (MIDLIFE IN THE UNITED STATES (MIDUS), 1995-1996 [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 twins and the siblings of main sample respondents), and its creative use of in-depth assessments in key areas (e.g., daily stress and cognitive functioning). A description of the study and findings from it are available at http://www.midus.wisc.edu. With support from the National Institute on Aging, a longitudinal follow-up of the original MIDUS samples: core sample (N = 3,487), metropolitan over-samples (N = 757), twins (N = 925 complete pairs), and siblings (N = 950), was conducted in 2004-2006. Guiding hypotheses for it, at the most general level, were that behavioral and psychosocial factors are consequential for physical and mental health. MIDUS 2 respondents were aged 35 to 86. Data collection largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas (e.g., cognitive functioning, optimism and coping, stressful life events, and caregiving). To add refinements to MIDUS 2, an African American sample (N = 592) was recruited from Milwaukee, Wisconsin, who participated in a personal interview and completed a questionnaire paralleling the above assessments. Survey data for the Milwaukee sample are available in a separate project [ICPSR 22840]. Also administered was a modified form of the mail questionnaire, via telephone, to respondents who did not complete a self-administered questionnaire.

Study of Dementia in Swedish Twins, 1990-1999 (ICPSR 25963)
Released/updated on: 2010-06-04
Geographic coverage: Sweden, Global
Time period: 1990-05-01--1999-03-01
The Study of Dementia in Swedish Twins was designed to study the relative influence of genetic and environmental factors for Alzheimer's disease and other types of dementia and to test the role of specific environmental exposures that might constitute risk or protective factors for dementia. The first seven years of the Study of Dementia in Swedish Twins was based on the population from the SWEDISH ADOPTION/TWIN STUDY OF AGING (SATSA), 1984, 1987, 1990, and 1993 (ICPSR 3843). SATSA consists of a subset of 3,838 same-sex twins from the population-based Swedish Twin Registry; however, the baseline sample for the Study of Dementia in Swedish Twins consists of 2,394 individuals who were alive and born in 1935 or earlier. The Study of Dementia in Swedish Twins data cover background information (sex, zygosity, rearing status, ages at each data collection point, age at death), cognitive screening (which took place in conjunction with each SATSA wave of data collection), clinical dementia diagnoses for those who received a complete dementia workup (both baseline and longitudinal), cognitive test results (both baseline and longitudinal), medical history and medical risk factors (medical examination; blood pressure; laboratory results; history of neurologic, coronary, mental, and other diseases; smell test; history of head injury, anaesthesia, fevers, medications, dietary history with respect to fish, raw meat, and acidic foods prepared in aluminum pans), residential, occupational, and leisure activities history (including exposure related to welding, hairdressing, agriculture, medical settings, painting and other sources of organic solvents, crystal, carbon monoxide, radiation, raw meat and game; participation in contact sports; antiperspirant containing aluminum; history of smoking; history of use of alcohol), family history of dementia, and APOE genotype. SATSA is archived separately at ICPSR, see ICPSR 3843. The SATSA and the Study of Dementia in Swedish Twins files contain a common ID number that can be used to create a crosswalk between the files.

Swedish Adoption/Twin Study on Aging (SATSA), 1984, 1987, 1990, 1993, 2004, 2007, and 2010 (ICPSR 3843)
Released/updated on: 2015-05-13
Geographic coverage: Sweden, Global
Time period: 1984-01-01--2010-01-01
The Swedish Adoption/Twin Study on Aging (SATSA) was designed to study the origins of individual differences in aging and the environmental and genetic factors that are involved. SATSA began in 1984, and six additional waves were conducted in 1987, 1990, 1993, 2004, 2007, and 2010. The questionnaire was initially sent to all twins from the Swedish Twin Registry who were separated at an early age and raised apart; the survey was also administered to a control sample of twins who were raised together. The respondents were surveyed on items that included health status, how they were raised, work environment, alcohol consumption, and dietary and smoking habits, as well as questions about personality and attitudes; this information comprised the first component. The second component was collected from a subsample composed of 150 pairs of twins raised apart and 150 pairs of twins raised together. This subsample participated in seven waves of in-person testing, which included a health examination, structured interviews, and tests on functional capacity, cognitive abilities, and memory. The data are represented according to questionnaire and time number, and correspond to each wave/year: Questionnaire 1 and In-Person Testing Time 1 were in 1984; Questionnaire 2 and In-Person Testing Time 2 were in 1987; Questionnaire 3 and In-Person Testing Time 3 were in 1990; Questionnaire 4 and In-Person Testing Time 4 were in 1993; Questionnaire 5 was in 2003; In-Person Testing Time 5 was in 2004; Questionnaire 6 and In-Person Testing Time 6 were in 2007; In-Person Testing Time 7 was in 2010. The Administrative and Cognitive datasets include data from all years/waves. The Smell Survey dataset only includes data from 1990. No years were specified for the Contact measures and Separation measures datasets. Demographic and background information includes age, sex, education, family history, household composition and employment.
