Americans' Changing Lives: Waves I, II, III, IV, V, and VI, 1986, 1989, 1994, 2002, 2011, and 2021 (ICPSR 4690)

Released/updated on: 2024-12-12
Geographic coverage: United States
Time period: 1986-01-01--2021-01-01

The Americans' Changing Lives (ACL) survey series is an ongoing, nationally representative, longitudinal study focusing especially on differences between Black and White Americans in middle and late life. These data constitute the first, second, third, fourth, fifth, and sixth waves in a panel survey covering a wide range of sociological, psychological, mental, and physical health items. Wave I of the study began in 1986 with a nation face-to-face survey of 3,617 adults ages 25 and up, with Black Americans and people aged 60 and over over-sampled at twice the rate of the others. Wave II constitutes face-to-face re-interviews in 1989 of those still alive. Survivors have been re-interviewed by telephone, and when necessary face-to-face, in 1994 (Wave III), 2001/02 (Wave IV), 2011 (Wave V), and 2019/21 (Wave VI).

Please note that for Wave VI, the majority of data collection occurred in 2019, with only a small subset (n=39) of participants surveyed in 2021.

ACL was designed and sought to investigate the following: (1) The ways in which a wide range of activities and social relationships that people engage in are broadly "productive," (2) how individuals adapt to acute life events and chronic stresses that threaten the maintenance of health, effective functioning, and productive activity, and (3) sociocultural variations in the nature, meaning, determinants, and consequences of productive activity and relationships. Among the topics covered are interpersonal relationships (spouse/partner, children, parents, friends), sources and levels of satisfaction, social interactions and leisure activities, traumatic life events (physical assault, serious illness, divorce, death of a loved one, financial or legal problems), perceptions of retirement, health behaviors (smoking, alcohol consumption, overweight, rest), and utilization of health care services (doctor visits, hospitalization, nursing home institutionalization, bed days). Also included are measures of physical health, psychological well-being, and indices referring to cognitive functioning.

Demographic information provided for individuals includes household composition, number of children and grandchildren, employment status, occupation and work history, income, family financial situation, religious beliefs and practices, ethnicity, race, education, sex, and region of residence.

These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.

Drawing on the principles of Whole Person Dementia Assessment (Mast, 2011) and Appelbaum and Grisso's (1988) decision-making model, this project developed a tool, the Lichtenberg Financial Decision Rating Scale (LFDRS). The conceptual model for the LFDRS questionnaire integrates the measurement of contextual variables with financial capacity assessment. The purpose of the study was to establish reliability and validity of the LFDRS and to collect data on normative financial decision-making by older adults.

The researchers posited that as financial exploitation of older adults increases, investigation and prosecution of these cases remains difficult for criminal justice professionals who must balance protection of older adults with their right to autonomy; and that both under and over-protection of older adults can lead to damaging consequences. The project goal was to develop a set of new financial decision-making screening and comprehensive measures for criminal justice professionals and non-criminal justice professionals to aid in detecting and prosecuting financial exploitation of older adults. The LFDRS (described above) is meant to be used by mental health professionals, specially trained in assessment of older adults. In addition, the researchers developed a 10-item screening tool, the Lichtenberg Financial Decision Screening Scale or Short Scale (LFDSS), that was tested by multiple professionals working in diverse settings (e.g., APS workers, elder law attorneys, law enforcement personnel).

Family members are another group that are often aware of an older adult's vulnerability to financial exploitation and therefore, the researchers developed the Lichtenberg Financial Decision Rating Scale -- Family and Friends version (LFDRS - Family and Friends also known as the LFDRS Informant) to allow concerned professionals to interview confidantes of older adults to help measure financial capacity of a loved one. This tool may be particularly useful for Adult Protective Services to interview multiple people regarding their concerns about an older adult.

The collection contains 3 SPSS data files:

  • LFDRS-Data-for-ICPSR.sav (200 cases, 109 variables)
  • LFDRS_Informant-Data-for-ICPSR.sav (150 cases, 45 variables)

Biodemographic Models of Reproductive Aging (BIMORA) Project, 1998-2002 [United States] (ICPSR 4452)

Released/updated on: 2006-10-25
Geographic coverage: United States
Time period: 1998-01-01--2002-01-01
In the early 1990s, researchers at Georgetown University, Pennsylvania State University, and the University of Utah proposed a five-year longitudinal study of female reproductive aging that would include the collection of hormonal, menstrual cycle, and health data from a group of women in order to advance the current understanding of the transition through menopause. The women selected for the BIMORA project were a subset of women belonging to the Tremin Research Program on Women's Health (TREMIN), a longitudinal, prospective study of menstrual cycles and female reproductive health that was begun in the 1930s by Dr. Alan Treloar at the University of Minnesota. As part of the TREMIN study, women recorded their menstrual cycles on calendar cards and were also asked to fill out annual and later biannual health surveys. The first cohort of women was recruited in the 1930s when many of them were attending the University of Minnesota. Some of their daughters, along with additional women, were recruited in the 1960s as part of a second cohort. Recruitment continued after the second cohort, and a total of 156 TREMIN women participated in the five-year BIMORA project. At the beginning of the study, they ranged in age from 25 to 58 years of age and many were from the second TREMIN cohort. Women could not be using exogenous hormones and had to have at least one intact ovary. The participating women had TREMIN data going back as far as the early 1960s, and they continued sending menstrual bleeding and health data to TREMIN during the BIMORA project. In addition, from January 15 to July 14 in each of the five years of the BIMORA project, participants collected daily urine specimens and made a daily record of medication use, health conditions, and menstrual bleeding. These data were analyzed in the BIMORA laboratory. The urine specimens were assayed for urinary conjugates of estrogen, progesterone, LH, and FSH. The TREMIN data and laboratory data were then merged into a single dataset.

Black Rural and Urban Caregivers Mental Health/Functioning, Missouri, 1999-2002 (ICPSR 36349)

Released/updated on: 2019-01-28
Geographic coverage: United States, Missouri
Time period: 1999-01-01--2002-01-01

The Black Rural and Urban Caregivers Mental Health/Functioning data collection includes survey data collected in 2000-2002 from African American females age 65 and older, who provide unpaid care for older African American adults in the St. Louis Metropolitan area and seven rural Missouri counties (Butler, Dunklin, Mississippi, New Madrid, Pemiscot, Scott, and Stoddard).

Because of inadequate recruitment knowledge about rural African American caregivers and persistent reports of challenges when involving African Americans elders in research, this study focused on the involvement of African American rural elders and recruitment of their female informal caregivers in a study of caregivers' well-being and service use. African Americans comprise the largest group of ethnic and racial minority elders aged 65 and older in the U.S. population thus making up one half of all ethnic and racial minority elders. Numerical changes in population size and increasing longevity of older African Americans direct attention to African American informal female caregivers- persons most likely to assist African American elderly with daily living tasks, personal needs, and long-term care. More disabled and chronically ill African American elders portend continuing need from informal or unpaid caregivers for dependent care.

There are two datasets associated with this study, a public-use (da36349-0001) and restricted-use (da36349-0002) version of the same survey data. Both data files contain 521 cases and 1438 variables. However, the restricted file contains continuous as opposed to categorical values for age variables rounded to the nearest whole number.

Boston Rehabilitative Impairment Study of the Elderly (Boston RISE), 2009-2015 (ICPSR 37045)

Released/updated on: 2021-01-28
Geographic coverage: Massachusetts, Boston
Time period: 2009-01-01--2015-01-01
The Boston Rehabilitative Impairment Study of the Elderly (Boston RISE) was a prospective cohort study of older primary care patients, aged 65 years and older, who were at risk for declining mobility and disability at baseline. The study was designed to investigate which combinations of neuromuscular impairments are most responsible for mobility decline and disability over 2 years of follow up. Through additional funding, Boston RISE continued to collect follow up data on the Late Life Function and Disability Instrument (LLFDI) and mobility-related and healthcare utilization outcomes over the phone as part of a 2-year extension. Several ancillary measures were also collected throughout the course of the study.

Bruising as a Forensic Marker of Physical Elder Abuse in Orange County, California, 2006-2008 (ICPSR 28144)

Released/updated on: 2012-12-21
Geographic coverage: United States, California
Time period: 2006-07-01--2008-05-01
The purpose of the study was to describe bruising as a marker of physical elder abuse. Consenting older adults were examined to document location and size of bruises and assess whether they were inflicted during physical abuse. An expert panel confirmed physical abuse. A research nurse conducted study assessments on 67 adults aged 65 and older reported to Adult Protective Services for suspected physical elder abuse in Orange County, California between July 2006 and May 2008. The study contains a total of 142 variables including age, sex, ethnicity, functional status, medical conditions, cognitive status, history of falls, bruise size, bruise location and color, recall of cause, and responses to the Revised Conflicts Tactics Scales (CTS2) and to the Elder Abuse Inventory (EAI).

Building Late-Life Resilience to Prevent Elder Abuse: A Randomized Controlled Pilot Study of the EMPOWER Program, Arizona, 2019-2021 (ICPSR 38332)

Released/updated on: 2023-08-14
Geographic coverage: United States, Arizona
Time period: 2017-01-01--2021-12-31

Over the past two decades, as the proportion of older Americans has increased, so too have instances of elder abuse, including physical, emotional, and sexual abuse; financial exploitation; and caregiver neglect. The most recent national survey estimates show at least 1 in 10 community-residing older adults experience elder abuse each year, which translates to over 7 million Americans annually. Rates of abuse are magnified for older adults with the least financial and social resources, including those with low incomes, living in isolated rural communities, and facing structural barriers such as systemic racism. Emerging research on the COVID-19 pandemic prompts even greater concern for elder abuse: the virus has disproportionately affected older adults, resulting in increased social isolation, physical health impairment, and exposure to COVID-related fraud.

Recognizing the urgent need to develop and rigorously evaluate programs aimed at preventing elder abuse, the US Department of Justice's National Institute of Justice funded a demonstration from 2017 to 2021 during which researchers from the Urban Institute and practitioners at the Phoenix-based Area Agency on Aging, Region One ("the Area Agency") co-developed an elder abuse prevention program in Maricopa County, Arizona, which Urban's team then evaluated through a randomized controlled pilot study. This multiphase demonstration included an initial planning phase and a subsequent pilot study, which is the focus of this report.

The EMPOWER: Building Late-Life Resilience program is a 12-week in-home intervention, with one-hour weekly visits designed to empower community-residing older adults with the resiliency and resources to lead safe and healthy lives throughout the aging process. EMPOWER provides one-on-one assessments, client-centered prevention education, and needs-responsive life skills training embedded in a series of cognitive reframing conversations with an experienced facilitator. The program has eight modules, each of which culminates in an action plan focused on strengthening a client's internal assets and identifying sources of positive social support. Caseworkers facilitate motivational discussions centered on clients' self-identified goals and action planning, with the aim of optimizing clients' home safety, physical health, social connectedness, and emotional and financial well-being.

Charleston Heart Study, Charleston, South Carolina, 1960-2000 (ICPSR 4050)

Released/updated on: 2021-06-03
Geographic coverage: Charleston (South Carolina), United States, South Carolina
Time period: 1960-01-01--2000-01-01
The Charleston Heart Study (CHS) represents data collected over a 41-year period (1960-2000) in order to provide an understanding of the natural progression of aging in a community-based cohort. In 1960 the CHS began enrolling a random selection of community residents who were 35 years of age and older -- including men and women, Black and White. The primary hypothesis of the original study was to investigate racial differences in the manifestation and risk factors for coronary disease. Over the ensuing 40+ years, a variety of outcome measurements were incorporated into the re-examination of the participants, including psychosocial, behavioral, aging, and functional measures. As a longitudinal study, the CHS allows for the study of the risk factors, correlates, and consequences of aging, while simultaneously allowing for exploration of racial disparity in the manifestation of putative risk factors and outcomes. The CHS began with baseline data and added a special cohort of Black men. In subsequent years three separate follow-ups were conducted. The data include death information for respondents and background characteristics (age, race, sex, occupation, education, and marital status).

Chicago Community Adult Health Study, 2001-2003 (ICPSR 31142)

Released/updated on: 2012-07-11
Geographic coverage: United States, Chicago, Illinois
Time period: 2001-01-01--2003-01-01

The Chicago Community Adult Health Study (CCAHS) consists of four interrelated components that were conducted simultaneously: (1) a survey of adult health on a probability sample of 3,105 Chicago adults, including direct physical measurements of their blood pressure and heart rate and of height, weight, waist and hip circumference, and leg length; (2) a biomedical supplement which collected blood and/or saliva samples on a subset of 661 survey respondents; (3) a community survey in which individuals described aspects of the social environment of all survey respondents' neighborhoods; and (4) a systematic social observation (SSO) of the blocks in which potential survey respondents resided, including a lost letter drop (Milgram et al. 1965) as an unobtrusive measure of neighborhood social capital/sense of responsibility to help others. The latter two extend a community survey and SSO of neighborhoods carried out by the Project on Human Development in Chicago Neighborhoods (PHDCN) in 1995. The adult health survey and the community survey were conducted jointly through face-to-face interviews with a stratified, multistage probability sample of 3,105 individuals aged 18 and over and living in the city of Chicago, with a response rate of 72 percent that is about the highest currently attainable in large urban areas. In addition, blood pressure, heart rate, and physical measurements (of height, weight, waist and hips, and leg length) were collected during the survey interview, and blood and saliva samples from 661 respondents or 60 percent of those doing the survey in the 80 "focal" neighborhood clusters (NCs). SSOs were conducted on 1,663 of the 1,672 city blocks on which each respondent lived. The CCAHS is the largest of five projects under the NIH-funded Michigan Interdisciplinary Center on Social Inequalities, Mind and Body Mind (#P50HD38986), one of five Mind-Body Centers funded by the National Institutes of Health in late 1999. This study will advance the understanding of socioeconomic and racial/ethnic disparities in health, a major priority of the Public Health Service and the National Institutes of Health.

The PI-supplied summary mentions that the study is comprised of four components. However, for the purposes of this data release there are three distinct datasets. Demographic variables include age, birth year, race, ethnicity, number of children in the household, number of children living elsewhere, number of times the respondent has been married, and relationship status, religious preference, and sex.

China Multi-Generational Panel Dataset, Liaoning (CMGPD-LN), 1749-1909 (ICPSR 27063)

Released/updated on: 2016-09-06
Geographic coverage: Asia, China (Peoples Republic)
Time period: 1749-01-01--1909-01-01
The China Multi-Generational Panel Dataset - Liaoning (CMGPD-LN) is drawn from the population registers compiled by the Imperial Household Agency (neiwufu) in Shengjing, currently the northeast Chinese province of Liaoning, between 1749 and 1909. It provides 1.5 million triennial observations of more than 260,000 residents from 698 communities. The population mainly consists of immigrants from North China who settled in rural Liaoning during the early eighteenth century, and their descendants. The data provide socioeconomic, demographic, and other characteristics for individuals, households, and communities, and record demographic outcomes such as marriage, fertility, and mortality. The data also record specific disabilities for a subset of adult males. Additionally, the collection includes monthly and annual grain price data, custom records for the city of Yingkou, as well as information regarding natural disasters, such as floods, droughts, and earthquakes. This dataset is unique among publicly available population databases because of its time span, volume, detail, and completeness of recording, and because it provides longitudinal data not just on individuals, but on their households, descent groups, and communities.

China Multi-Generational Panel Dataset, Shuangcheng (CMGPD-SC), 1866-1913 (ICPSR 35292)

Released/updated on: 2021-10-14
Geographic coverage: Asia, China (Peoples Republic)
Time period: 1866-01-01--1913-01-01
The China Multi-Generational Panel Dataset - Shuangcheng (CMGPD-SC) provides longitudinal individual, household, and community information on the demographic and socioeconomic characteristics of a resettled population living in Shuangcheng, a county in present-day Heilongjiang Province of Northeastern China, for the period from 1866 to 1913. The dataset includes some 1.3 million annual observations of over 100,000 unique individuals descended from families who were relocated to Shuangcheng in the early 19th century. These families were divided into 3 categories based on their place of origin: metropolitan bannermen, rural bannermen, and floating bannermen. The CMGPD-SC, like its Liaoning counterpart, the CMGPD-LN (ICPSR 27063), is a valuable data source for studying longitudinal as well as multi-generational social and demographic processes. The population categories had salient differences in social origins and land entitlements, and landholding data are available at a number of time periods, thus the CMGPD-SC is especially suitable to the study of stratification processes.

Community Tracking Study Household Survey, 1996-1997, and Followback Survey, 1997-1998: [United States] (ICPSR 2524)

Released/updated on: 2024-02-14
Geographic coverage: United States
Time period: 1996-07-01--1997-07-01, 1997-10-01--1998-08-01
This data collection comprises two components of the Community Tracking Study (CTS), the Household Survey and the Followback Survey. The CTS, sponsored by the Robert Wood Johnson Foundation, is a national study designed to track changes in the health care system and their effects on care delivery and individuals. Central to the design of the CTS is its community focus. Sixty sites (51 metropolitan areas and 9 nonmetropolitan areas) were randomly selected to form the core of the CTS and to be representative of the nation as a whole. The Household Survey was administered to households in the 60 CTS sites and to a supplemental national sample of households. At the beginning of each interview, a household informant was identified and queried about the composition of the household. With this information, individuals in the household were grouped into family insurance units (FIU). An FIU reflects family groupings typically used by insurance carriers. It includes an adult household member, his or her spouse, if any, and any dependent children 0-17 years of age (or 18-22 years of age if a full-time student). Family informants, selected from each FIU in the household, provided information on health insurance coverage, health care use, usual source of care, and the general health of all persons in the FIU. These informants also provided information on family income and out-of-pocket expenses for health care, as well as employment, race, and Hispanic origin for all adult FIU members. Each adult in the household, including the FIU informants, responded through a self-response module to questions regarding unmet health care needs, patient trust, satisfaction with physician choice, limitations in daily activities, smoking behaviors, and last doctor visit. In FIUs with more than one child under 18, only one child was randomly selected for inclusion in the survey. The family informant responded on behalf of the child regarding unmet needs and satisfaction with physician choice. The adult family member who took this child to his or her last doctor visit responded to questions about the visit. The Followback Survey was designed to obtain detailed information on private health insurance coverage reported in the Household Survey. It was administered to health plans and other organizations that offered or administered the comprehensive private health insurance policies covering Household Survey respondents in the 60 CTS sites. Information on private health insurance policies collected by the Followback Survey includes product type, gatekeeping, consumer cost sharing, provider payment methods, and coverage of mental health and/or substance abuse services.

This collection comprises the second round of the Community Tracking Study (CTS) Household Survey and the second round of the CTS Followback Survey. The CTS, sponsored by the Robert Wood Johnson Foundation, is a national study designed to track changes in the health care system and their effects on care delivery and individuals. Fifty-one metropolitan areas and nine nonmetropolitan areas were randomly selected to form the core of the CTS and to be representative of the nation as a whole. As in the first round of the Household Survey (COMMUNITY TRACKING STUDY HOUSEHOLD SURVEY, 1996-1997, AND FOLLOWBACK SURVEY, 1997-1998: [UNITED STATES] (ICPSR 2524)), the second round of the Household Survey was administered to households in the 60 CTS sites and to a supplemental national sample of households. Respondents provided information about household composition and demographic characteristics, health insurance coverage, use of health services, unmet health care needs, out-of-pocket expenses for health care, usual source of care, patient trust and satisfaction, last visit to a medical provider, health status and presence of chronic health conditions, risk behaviors and smoking, and employment, earnings, and income. The purpose of the Followback Survey was to obtain detailed information on private health insurance coverage reported in the Household Survey. It was administered to the health plans and other organizations (managed care organizations, third-party administrators, employer or union plans, and employers) that offered or administered the respondents' comprehensive private health insurance policies. Information on private health insurance policies collected by the Followback Survey includes product type, gatekeeping, consumer cost sharing, provider payment methods, and coverage of mental health and/or substance abuse services.

Sponsored by the Robert Wood Johnson Foundation, this survey is one component of the Community Tracking Study (CTS), a national study designed to track changes in the health care system and the effects of the changes on care delivery and on individuals. Central to the design of the CTS is its community focus. Sixty sites (51 metropolitan areas and 9 nonmetropolitan areas) were randomly selected to form the core of the CTS and to be representative of the nation as a whole. The Physician Survey was administered to physicians in the 60 CTS sites and to a supplemental national sample of physicians. Information gathered by the survey instrument includes physician supply and specialty distribution, practice arrangements and physician ownership of practices, sources of practice revenue, level and determinants of physician compensation, effects of care management strategies, and physicians' allocation of time, provision of charity care, career satisfaction, and perceptions of their ability to deliver care. For primary care physicians, the survey instrument also provided vignettes of various clinical presentations for which there was no prescribed method of treatment. These physicians were asked to indicate the percentage of patients for whom they would recommend the course of action specified in each particular vignette. Part 3, the Site and County Crosswalk Data File, describes which counties constitute each site. Part 4, the Physician Survey Summary File, contains site-level averages and percentages and standard errors of these estimates for selected attributes, e.g., the percentage of physicians who were foreign medical school graduates, average age of physicians, average percentage of patient care practice revenue from Medicaid, etc.

Community Tracking Study Physician Survey, 2000-2001: [United States] (ICPSR 3820)

Released/updated on: 2024-02-14
Geographic coverage: United States
Time period: 2000-01-01--2001-01-01
This study comprises the third round of the physician survey component of the Community Tracking Study (CTS). Sponsored by the Robert Wood Johnson Foundation, the CTS is a large-scale investigation of changes in the health care system and their effects on people. Central to the design of the CTS is its community focus. Sixty sites (51 metropolitan areas and 9 nonmetropolitan areas) were randomly selected to form the core of the CTS and to be representative of the nation as a whole. As in the first two rounds of the physician survey, COMMUNITY TRACKING STUDY PHYSICIAN SURVEY, 1996-1997: [UNITED STATES] (ICPSR 2597) and COMMUNITY TRACKING STUDY PHYSICIAN SURVEY, 1998-1999: [UNITED STATES] (ICPSR 3267), the third round was administered to physicians in the 60 CTS sites and to a supplemental national sample of physicians. The survey instrument collected information on physician supply and specialty distribution, practice arrangements and physician ownership of practices, physician time allocation, sources of practice revenue, level and determinants of physician compensation, provision of charity care, career satisfaction, physicians' perceptions of their ability to deliver care, effects of care management strategies, and various other aspects of physicians' practice of medicine. Part 3, the Site and County Crosswalk Data File, identifies the counties that constitute each CTS site. Part 4, Physician Survey Summary File, contains site-level estimates and standard errors for selected physician characteristics, e.g., the average age of physicians, the percentage of physicians who were either very or somewhat dissatisfied with their overall career in medicine, and the average percentage of patients with prescription coverage that included the use of a formulary.

This was a two phase project designed to investigate the decision-making process of the coroner/medical examiner (CME) offices who are charged with investigating suspicious elder deaths and to pilot an intervention that augmented the decision-making process in three CME offices. In phase one, researchers collected case data from CME offices, public data on elder deaths, and interviews with CME investigators. Researchers then developed a brief screening tool, Elder Suspicious Death Field Screen (ESDFS), to be used by CME employees fielding reports of elder deaths. In phase two, the ESDFS was implemented in three counties for a six-month data collection period. An expert panel reviewed a subsample of cases to assess whether CME investigators made appropriate decisions to investigate or not.

Course of Domestic Abuse Among Chicago's Elderly: Risk Factors, Protective Behaviors, and Police Intervention, 2006-2009 (ICPSR 29041)

Released/updated on: 2013-04-23
Geographic coverage: United States, Chicago, Illinois
Time period: 2006-04-01--2009-10-01
The study was conducted to examine if and how risk factors and protective behaviors affect the course of elder abuse over time, and the role of police in intervening with elderly victims of domestic abuse and/or neglect. It also examined the prevalence rates for various types of abuse using a stratified sample of Chicago's elderly population. The study involved in-depth interviews with 328 elderly (aged 60 and over) residents of Chicago from three sample groups: (1) 159 community nonvictims; (2) 121 community victims; and (3) a police sample consisting of 48 elderly victims who had been visited by trained domestic violence/senior citizen victimization officers in the Chicago Police Department. The interviews were conducted using a survey instrument designed to assess victimization. The survey included questions about various characteristics and risk factors associated both with victims and perpetrators of abuse and/or neglect, specific types of abuse, and protective behaviors of victims. Victimization was examined twice over a 10-month period to evaluate the course of abuse over time. The efficacy of police intervention was also examined.

Danish 1905 Cohort Study, 1998 (ICPSR 3960)

Released/updated on: 2016-08-22
Geographic coverage: Denmark, Global
Time period: 1905-01-01--1998-01-01
This data collection provides information on individuals born in Denmark in 1905 and who were still living in Denmark in 1998. The overall goal of the study was to establish a genetic-epidemiological database to shed light on the aging process among the extremely old. The data focus on their physical and cognitive functioning. Respondents were asked if they had been previously diagnosed with diseases such as diabetes, arthritis, asthma, migraine, cancer, stroke, heart attack, or depression, and if they were experiencing such ailments as cough, body pains, and bone fracture and were taking medication for them. Questions probed respondents' feelings about their health, life, and future. To assess respondents' general health and functioning, they were asked if they needed assistance with toileting, bathing, dressing, and mobility around the house; how often they needed to use the bathroom during the night; and if they used physical aids such as wheelchairs, eyeglasses, crutches, catheters, or diapers. They were also tested for memory and cognition, mobility, vision, speech, hearing, and lung functioning. Information was also elicited on respondents' mental state and awareness, energy level, menopause, frequency of visits with children and family, visits from a nurse, use of home care services, sleeping patterns, smoking and drinking habits, weight gain or loss, exercises, social activities, hobbies, reading habits, television viewing, and recent deaths in the family. Demographic information includes age, education, and marital status.

Developing a Taxonomy To Understand and Measure Outcomes of Success in Community-Based Elder Mistreatment Interventions, New York City, New York, 2018-2019 (ICPSR 37955)

Released/updated on: 2022-06-29
Geographic coverage: New York City, Queens, United States, Brooklyn, New York (state), Manhattan (New York City)
Time period: 2018-01-01--2019-01-01

Research tools available to help advance knowledge of effective community-based elder mistreatment (EM) interventions are limited. The field lacks an understanding of what success means in EM response program (EMRP) interventions, which work directly with victims to reduce the risk of re-victimization. Without establishing indicators of EMRP success, it is not possible to develop valid intervention outcome measures to compare different EMRP models toward the development of evidence-based practice. Informed by the EMRP practice principle of older adult self-determination, this study developed a victim-centric taxonomy of case outcomes that indicate EMRP success.

This study drew on two sources of data, including interviews with EM victims and a scoping review to inform taxonomy development. Prioritizing the perspective of victims, this study conducted interviews with 27 victims involved in EMRP services who vary in EM subtype, gender, and race/ethnicity.

The taxonomy of successful EMRP outcomes will serve as important research infrastructure to support the development of EMRP intervention outcome measurement in future research.

Development of a Brief Elder Abuse and Neglect Screening Tool for Emergency Medical Services: Detection of Elder Abuse Through Emergency Care Technicians (DETECT), Texas, 2015 (ICPSR 37245)

Released/updated on: 2022-08-30
Geographic coverage: United States, Texas
In collaboration with Texas Adult Protective Services (APS) and one of the largest mobile healthcare providers in North Texas -- MedStarMobile Healthcare (MedStar) -- this study developed and piloted an elder abuse (EA) screening tool: Detection of Elder Abuse Through Emergency Care Technicians (DETECT). The DETECT tool was designed specifically to help medics identify potential EA among community-dwelling older adults during an emergency response. DETECT relies entirely on the medics' systematic observations of the older adults' physical and social environment -- no direct questioning of the older adult or their caregivers is involved. The DETECT tool was developed through an iterative, user-centered design process in which input was gathered from key stakeholders, and revisions to the tool incorporated their feedback. The intent was for that process to result in an EA screening tool that was easy for medics to use in the field and that helped medics capture information about older adults, their environments, and their caregivers that is thought to be associated with the occurrence of EA.

The purpose of this study was to investigate violence and aggression committed by nursing home residents that is directed toward other residents, referred to here as resident-to-resident elder mistreatment (R-REM). Resident-to-resident mistreatment (R-REM) was defined as: negative and aggressive physical, sexual, or verbal interactions between long term care residents, that in a community setting would likely be construed as unwelcome and have high potential to cause physical or psychological distress in the recipient.

The goals of this project were to: enhance institutional recognition of R-REM; examine the convergence of R-REM reports across different methodologies; identify the most accurate mechanism for detecting and reporting R-REM; develop profiles of persons involved with R-REM by reporting source; investigate existing R-REM policies, and; develop institutional guidelines for reporting R-REM episodes. Also, the project team sought to answer the following research questions: (1) Will the reporting of R-REM differ by source? (2) Which reporting methods will show the highest level of convergence and accuracy in reporting? (3) What resident characteristics or profiles will predict R-REM across the differing reporting sources? (4) What are the existing guidelines and/or institutional policies for reporting R-REM? To achieve these goals, the researcher conducted this study over a two week period in five urban and five suburban New York City facilities. Resident-to-resident abuse information was derived from five sources: (1) resident interviews (2) staff informants (3) observational data (behavior sheets) (4) resident chart reviews (5) incident and accident reports.

Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.

The purpose of the study was to:

  • Examine resident abuse from staff report by direct care workers in a nationally representative sample of assisted living settings;
  • Expand the scope of our understanding of resident abuse by including medication abuse in assisted living settings; and
  • Use the data collected to examine: a. rates of abuse; b. the association of external organizational, and internal factors with resident abuse; c. direct care worker characteristics associated with abuse; d. resident characteristics associated with abuse; e. leadership characteristics associated with abuse; f. the inter-correlations of different types of abuse; and, g. resident-to-resident abuse.

For the purposes of this research, an assisted living facility is defined as a long term care setting that typically provides residents for activities of daily living and instrumental activities of daily living. Using state listings from websites, researchers identified approximately 21,000 of assisting living facilities. A random sample of approximately seven percent (n=1,500) of these eligible assisted living facilities were selected from all 50 states. Administrators of assisted living facilities were asked if they were willing to complete the questionnaire (n=1,376). Administrators were also asked if they would be willing to distribute the questionnaire to direct care workers (n=12,555). Researchers requested that they distribute the survey to all full-time and part-time direct care workers on all shifts. Follow up reminder mailings and emails were used for the administrators.

Financial Abuse of Elderly People vs. Other Forms of Elder Abuse in Virginia, 2003-2008 (ICPSR 29301)

Released/updated on: 2015-06-26
Geographic coverage: United States, Virginia
Time period: 2003-01-01--2008-01-01

This study examined financial exploitation of elderly people compared to other forms of elder maltreatment (physical abuse, neglect, and hybrid, i.e., financial exploitation and physical abuse and/or neglect) that occurred in a domestic setting. The cases were explored by obtaining information from a variety of sources including:

  • Three different individuals about a given case including (1) the caseworker from APS that managed the reported case, (2) the person who had been reported to have experienced elder abuse and, (3) where they were available, a non-offending third party who knew the elder at the time of the APS response to the report of elder abuse (e.g., the elder's domestic partner, care provider, friend, or family member).
  • Data derived from the Virginia Department of Social Services' Adult Services Adult Protective Services (ASAPS) Database which contains information drawn from several sources.
  • Prosecutors in four states that were interviewed about their experience prosecuting elder abuse, barriers and facilitators associating with prosecuting such cases, and possible reforms.

The specific goals of this research were to (1) Determine unique aspects of financial exploitation as compared to other forms of elder maltreatment, including risk factors, reporting, investigation, and case outcomes; (2) Determine the degree of congruence between the perceptions of victims of elder maltreatment and APS caseworkers regarding these cases; and (3) Develop recommendations based on these findings for addressing the financial abuse of the elderly.

Financial Exploitation and Psychological Abuse of Older Adults in the Chicago Metropolitan Area, 2007-2008 [United States] (ICPSR 26881)

Released/updated on: 2013-01-11
Geographic coverage: United States, Chicago, Illinois
Time period: 2007-01-01--2008-01-01
The research team developed two self-reporting questionnaires, the Older Adult Mistreatment Assessment (OAMA) Client Questionnaire and the OAMA Staff Questionnaire, in order to measure for financial exploitation and psychological abuse of the elderly. The OAMA Client Questionnaire was administered to clients aged 60 years and over who had been substantiated for at least one form of elderly mistreatment within the Chicago metropolitan area. In addition, a corresponding Staff Questionnaire was administered to each evaluator involved in the field test and submitted on behalf of each client in the study. In all, 227 client interviews with 227 corresponding staff questionnaires were compiled between 2007 and 2008, and scales were developed for measurements of both financial exploitation and psychological abuse. Financial exploitation of the elderly was measured through variables related to theft, scams, coercion, signs of abuse or financial entitlement by trusted friends or family members, and money management difficulties. Psychological abuse of the elderly was measured through variables related to isolation, disrespect, exploited vulnerability, shame, threats and intimidation, and risk factors related to the client's trusted friends or family.

Geographic coverage: Gainesville, United States, Orlando, Fort Lauderdale, St. Petersburg, Florida, Tampa, Jacksonville, Miami
Time period: 2007-01-01--2008-01-01
The purpose of this project was to develop and pilot test an interviewer-administered self-report questionnaire that might be used in a subsequent national survey to scientifically establish the prevalence of second-party elder abuse or neglect. The project focused only on those living in the communities who were capable of accurately self-reporting their knowledge, attitudes, and practices. Through focus groups of adult protective services and abuse hot-line staff, questionnaire items were generated and later tested through interviews of clients of aging services in Florida. Aging services case managers screened and recruited 95 clients, aged 65 and older, with 25 clients who had reports of mistreatment within the hotline database, and 70 comparison clients (no reports of mistreatment). Groups were matched by gender and age within 10 years. The interviews were conducted over an 18-month period, of which 3 interviews were conducted in-person and 92 interviews were conducted by telephone. All interviews were conducted by trained interviewers of the research team. Twenty-six interviews were conducted in Spanish. Interviews focused on demographics; activities of daily living; 19 possible types of elder abuse or neglect within the previous year, and, for each positive response, questions about the perpetrators and their relationship to the older adult; a description of when the mistreatment happened, how often, what the respondent did, and whether it was related to the perpetrator's anger, neglect, or carelessness.

The Generations study is a five-year study designed to examine health and well-being across three generations of lesbians, gay men, and bisexuals (LGB). The study explored identity, stress, health outcomes, and health care and services utilization among LGBs in three generations of adults who came of age during different historical contexts. This collection includes baseline, wave 1, and wave 2 data collected as part of the Generations study.

The study aimed to assess whether younger cohorts of LGBs differed from older cohorts in how they viewed their LGB identity and experienced stress related to prejudice and everyday forms of discrimination, as well as whether patterns of resilience differed between different LGB cohorts. Additionally, the study sought to examine how differences in stress experience affected mental health and well-being, including depressive and anxiety symptoms, substance and alcohol use, suicide ideation and behavior, and how younger LGBs utilized LGB-oriented social and health services, relative to older cohorts.

In wave 2, respondents were re-interviewed approximately one year after completion of the baseline (wave 1) survey. Only respondents who participated in the original sample of participants were surveyed at wave 2 (i.e., the enhancement oversample was not included in the longitudinal design of this study).

In wave 3, respondents were re-interviewed approximately one year after the completion of the wave 2 survey.

Demographic variables collected as part of this study include questions related to age, education, race, ethnicity, sexual identity, gender identity, income, employment, and religiosity.

The Hawaii Personality and Health Cohort, 1959-1967: Childhood Personality Data (ICPSR 36737)

Released/updated on: 2017-05-17
Geographic coverage: United States, Hawaii, Kauai, Oahu
Time period: 1959-01-01--1967-01-01

The Hawaii Personality and Health Cohort consists of teacher ratings of their students' personalities. John M. (Jack) Digman orchestrated the collection of the child personality data between 1959 and 1967, during his tenure as a professor at the University of Hawaii. Childhood data was collected on 2418 children in classrooms on the islands of Oahu and Kauai. Six waves of data collection were completed, and eighty-eight teachers provided assessments of their students. Children ranged in age from 5 to 14, and were in grades 1,2,3,5 or 6.

The initial goal of this work was to generate ratings using a broad set of items to allow for research on the structure of personality in childhood. The data collection predated the acceptance of the Big Five model of personality. Items were selected to capture the entire range of observable personality, which at the time was thought to be characterized by 10 or more domains. Subsequent analysis by Dr. Digman, and later by Lewis R. (Lew) Goldberg, demonstrated a consistent five factor structure in the child personality data. In the early days of the emergence of the Big Five model of personality structure, the Hawaii child data provided initial evidence to support the acceptance of Big Five model of personality.

Subsequent follow-up of the sample in adulthood has included multiple questionnaires, and assessments of objective markers of health. These follow-up data allowed for the first ever assessment of the stability in the Big Five over a span of 40 years. At average age 50, participants were recruited for a half day clinic visit. Objective markers of health collected at this time have supported work testing childhood personality as a predictor of physical health, and also research testing lifespan pathways linking childhood personality to physical health in adulthood.

This initial release includes the full childhood cohort data. Also included are a set of Big Five scores that have been used in published research on the Hawaii Personality Cohort, and a number of different sets of personality scales derived from these data. Basic demographic information is also provided. Subsequent data releases will include questionnaire and clinic data collected in adulthood.

For additional information about the correspondence between these datasets, please see the accompanying Excel file, which provides a table of overlapping variables across the datasets. Further information about this crosswalk file can be found in the "Item Overlap" section of the accompanying Study Description document.

Demographic variables included in this study include gender, cultural identity, and year of birth.

HIV Stigma in a Population of Adults Age 50 and Over in the Pacific Northwest, 2003-2005 (ICPSR 33242)

Released/updated on: 2013-03-29
Geographic coverage: United States
Time period: 2003-01-01--2005-01-01

Older adults are increasingly becoming impacted by HIV disease, both as newly infected individuals and as long-term survivors of HIV/AIDS living into older age. HIV-related stigma impacts the quality of life of all persons with HIV/AIDS. However, little is known about HIV-related stigma in older adults because many studies do not include older subjects or ignore age as a variable. This mixed methods study examined the experiences of HIV-related stigma in a sample of 25 older adults with HIV/AIDS from the Pacific Northwest. Quantitative methods measured HIV stigma and depression, while in-depth qualitative interviews captured the lived experiences of these individuals. Stigma was positively and significantly correlated with depression and stigma was found to be significantly higher in African American, as compared to White informants. Qualitative interviews yielded 11 themes that correspond to the four categories constructed in the stigma instrument. Rejection, disclosure concerns, stereotyping, protective silence and feeling "other", were all common experiences of these individuals.

Hospitalized Older Persons Evaluation (HOPE) Study, 1991-1993: [California] (ICPSR 6560)

Released/updated on: 2006-01-12
Geographic coverage: United States, California
Time period: 1991-03-01--1993-05-31
The HOPE study was a multi-center randomized clinical trial mounted to determine the effects of hospital inpatient consultative comprehensive geriatric assessment (CGA) under typical practice conditions on selected patient health and health services utilization outcomes. The main outcome measures were functional status, health status, mortality, rehospitalization, and total use of health care services for hospital patients 65 years of age and older. Functional status was evaluated by questions about limitations in patients' activities of daily living due to health problems. Also included were items covering living arrangements (with whom and where), ethnicity, education, and marital status. Health status questions covered patients' perceptions of mental health and current physical health. The functional and health status of patients was measured prior to CGA treatment and randomization, again at 3 months post-randomization, and at 12 months post-randomization. Functional and health status data are included in Parts 3-8. Health services utilization data (Parts 9-15) cover patient use of medical services such as urgent care, emergency room, radiology, durable medical equipment, and medications (prescribed and over the counter). Mortality information (Part 17) includes date of lost contact or death, and data source of survival status. Hospitalization measures (Part 18) include date of admission and discharge, admittance source diagnoses and procedures, and inpatient/outpatient status.

Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.

Financial elder exploitation (FE) is an increasing problem for vulnerable elders exploited by opportunists and for the social service and criminal justice system designed to protect them. This study systematically investigated both objective and subjective measures of social support and isolation, along with common risk factors mentioned in FE theories, including dependency, physical health, depression, cognition, and demographic characteristics. Researchers collected data on individual difference variables with an emphasis on cognitive factors and data on contextual factors using an individually administered survey approach. The framework for this project was derived from known factors for FE, predicted protective factors for FE, and conceptual approaches from the child mistreatment literature on risk and resilience.

The study includes 1 SPSS data file with 216 cases and 297 variables.

The Impact of a Forensic Collaborative for Older Adults on Criminal Justice and Victim Outcomes: A Randomized-Control, Longitudinal Design, Denver, Colorado, 2014-2018 (ICPSR 37167)

Released/updated on: 2020-07-30
Geographic coverage: United States, Colorado, Denver
Time period: 2014-01-01--2018-01-01

Initially funded in 2013 by the National Institute of Justice, the primary purpose of this project was to conduct a randomized-control test of the impact of a victim-focused, forensic collaborative relative to usual care (UC) on older adult victims' health, mental health, and criminal justice outcomes. During the course of the project, researchers responded to enrollment and consent challenges by implementing Arm 2 that focused on collecting caseworker and victim advocate perceptions of cases as well as administrative data from Adult Protective Services (APS).

This collection contains 6 datasets:

  • Arm 1 (DS1) contains survey results from victim-focused interviews of 40 older adults who were reported to be victims of abuse, neglect, and/or financial exploitation over 4 time points. Variables describe victim and case characteristics, service use/needs, risk factors for abuse, consequences of abuse and exploitation, and criminal justice process and outcomes.
  • Arm 2 (DS2) includes a survey of APS caseworkers reporting on a case of older adult abuse, such as client (older adult victim) and perpetrator demographics, mistreatment details (verbal abuse, physical abuse, sexual abuse, neglect, financial exploitation, and/or housing exploitation), and service use.
  • Collateral assessments (DS3) surveyed a trusted individual related to the older adult respondent in Arm 1. This included data on the perceptions of the older adult's functioning and use of services; and the quality of decision-making procedures, desired treatment, and outcomes in the criminal justice system. Of the 40 Arm 1 participants interviewed, 33 gave collateral contact information. Of those 33, 16 could not be reached, one failed the consent quiz, and two declined to participate. Of the 14 who participated in an initial interview, only three participated at the follow-up nine months later.
  • Revictimization and Prosecutorial Outcome Data (DS5) includes information on new incidents reported to law enforcement over the nine months following the original incident report and prosecution outcomes, gathered from publicly-accessible police reports and court information for Arm 1 and Arm 2 cases.
  • APS administrative data (DS6), such as the demographics of the older adult victim and the primary perpetrator, assessment scores for risk and safety, the alleged mistreatment type, whether mistreatment was substantiated, and APS case status. The data included overall risk/safety scores and summary scores for the domains of physical functioning, environmental context, financial resources, mental health, cognition, medical issues, and mistreatment.

Arm 1 demographic variables includes age, gender, education, employment status, marital status, household size, ethnic minority, and income source. Arm 2 surveys reported ethnicity, gender, age, education, marital status, and employment status; APS data reported age and gender.

Local Health Department Infrastructure Study, 1999-2000: [United States] (ICPSR 3185)

Released/updated on: 2024-02-14
Time period: 1999-01-01--2000-01-01
The purpose of this survey was to address the paucity of current data on the United States' local public health infrastructure and to advance understanding of the many ways local public health agencies contribute to keeping the nation's population and environment healthy. The survey collected information on local health department (LHD) characteristics (e.g., type of jurisdiction served, office to which the LHD reported directly, total expenditures, and sources of the LHD's total budget), priority program areas, and public health services provided directly or through contracts with others. Additional data cover LHD workforce composition, staffing needs, workforce training, and partnerships and collaborations with other groups and organizations, such as state or federal agencies, hospitals, HMOs, community health centers, universities, community-based organizations, professional associations, faith communities/churches, and business/private corporations. LHDs also reported on completion of community health assessments and development of community health improvement plans.

Longitudinal Study of Aging Danish Twins, 1995 (ICPSR 21041)

Released/updated on: 2009-06-09
Geographic coverage: Denmark, Global
Time period: 1995-02-01--1995-04-01
The focus of the "Longitudinal Study of Aging Danish Twins (LSADT)" was on elucidating the causes of variation in survival, health, diseases, loss of abilities, and cognitive functions among the elderly and oldest-old. The LSADT was conducted every two years between 1995 and 2005 and consists of six waves. The study is comprised of interviews of elderly Danish twins aged 75 years and older (later 70 years and older). At each interview wave, the interview assessment was based on the interview used in the previous waves, which covers health, physical functioning, cognitive functioning, depression symptomatology, social factors, lifestyle characteristics, and quality of life. The self-report interview assessments were supplemented with objective indicators of physical strength and agility, behavioral speed, and pulmonary peak-flow. Biological material was also collected from the participants for future DNA analysis.

Mass Marketing Elder Fraud Intervention, United States, 1999-2023 (ICPSR 39001)

Released/updated on: 2025-05-14
Geographic coverage: United States
Time period: 1998-06-06--2023-07-26

Estimates suggest that up to 16% of American adults--approximately 40 million people--fall victim to mass marketing scams each year. Mass marketing scams include any attempts to fraudulently solicit money from consumers through mass communication methods, such as the internet, telephone, and mail. Complaints to consumer protection agencies have risen 240% in the past 10 years (Federal Trade Commission [FTC], 2013, 2023). According to conservative estimates from the most recent Consumer Sentinel Network Report (FTC, 2023), Americans reported more than $2.7 billion in direct losses from fraud in 2022. In addition to financial costs, consequences to victims include feelings of shame and embarrassment, loss of trust, depression, and, in the most severe cases, suicidal ideation. These consequences of fraud are particularly impactful for older adults who suffer higher losses per incident, on average (FTC, 2022) and face greater challenges recovering from losses after retirement. Research on elder mistreatment in general has shown that older victims consume 30% more mental health and substance abuse services and are hospitalized more often than non-victims.

These scams convince susceptible targets that they have won bogus sweepstakes, merchandise, free vacations, or lotteries, but they first need to pay money to claim their winnings. Based on data from one major investigation from 2011 to 2016, the United States Postal Inspection Service (USPIS) found that Americans sent $558 million in checks, credit card payments, and money orders through the mail in response to such scams (USPIS internal data). Overall, the USPIS estimates that 3% of U.S. adults--7.5 million Americans--have mailed a payment in response to mass marketing fraud and that 60%-70% of these individuals are revictimized by a similar solicitation or an entirely different offer. Given these figures, reducing the incidence of mass marketing fraud could save millions of dollars annually.

Although the FTC, the National Council on Aging, the Consumer Financial Protection Bureau, the Better Business Bureau, American Association of Retired Persons (AARP), and other agencies and organizations routinely disseminate fraud education and awareness materials, it is unclear how much of these materials reach the most vulnerable populations. Much of the content is available online, yet according to the Pew Research Center, only 75% of adults older than age 65 use the internet, and only 64% have home broadband. Printed materials are also disseminated at senior centers, libraries, legal service offices, and outreach events, but older adults who are socially isolated and most susceptible to fraud are unlikely to be reached through these venues.

To address gaps in intervention research, Research Triangle Institute (RTI) International and the University of Minnesota conducted the Mass Marketing Elder Fraud Intervention (MMEFI) Study with collaboration and support from the USPIS. This multiphase research project included a secondary analysis of USPIS administrative data on prior scams and a randomized controlled trial test of the efficacy of two variations of a mailed intervention for preventing revictimization by mail fraud. The overall objective was to provide specific policy recommendations to the USPIS and other consumer protection agencies regarding the effectiveness of a mailed intervention. The MMEFI Study had the following specific goals:

  • Enhance knowledge and understanding of repeat victimization among older victims of mass marketing scams.
  • Engage in rigorous testing of the efficacy of two versions of a fraud intervention strategy geared toward preventing repeat victimization among older victims of mass marketing scams.
  • Assess victims' perceptions of the intervention and collect self-report data on experiences with other types of fraud by surveying individuals in the intervention study.

Midlife in the United States (MIDUS 2): Milwaukee African American Sample, 2005-2006 (ICPSR 22840)

Released/updated on: 2024-02-26
Geographic coverage: Milwaukee, United States, Wisconsin
Time period: 2005-01-01--2006-01-01
As a refinement to Midlife in the United States (MIDUS 2), 2004-2006 (ICPSR 4652), a sample of African Americans from Milwaukee was included to examine health issues in minority populations. Areas of the city of Milwaukee, Wisconsin, were stratified according to the proportion of the population that were African American. Those areas with high concentrations were sampled at higher rates than areas with lower concentrations. Area probability sampling methods were used along with population counts from the 2000 United States Census to identify potential respondents. Field interviewers screened households to determine if they contained any African American adults. There was additional screening to achieve an appropriate age/gender distribution in a manner similar to what was done for the original MIDUS sample Midlife in the United States (MIDUS 1), 1995-1996 (ICPSR 2760). Milwaukee respondents were interviewed in their homes using a Computer Assisted Personal Interview (CAPI) protocol and afterwards asked to complete a Self-Administered Questionnaire (SAQ). All measures paralleled those used in the larger MIDUS 1 and 2 samples. After successful completion of the Project 1 survey, some participants were eligible to participate in other MIDUS projects (2 through 5). Survey data was collected for 592 individuals.

Midlife in the United States (MIDUS 3): Milwaukee African American Sample, 2016-2017 (ICPSR 37120)

Released/updated on: 2023-03-16
Geographic coverage: Milwaukee, United States, Wisconsin
Time period: 2016-01-01--2017-01-01

In 2005, 592 African Americans from Milwaukee were added to the MIDUS sample to examine health issues in minority populations (for more details, see Midlife in the United States (MIDUS 2): Milwaukee African American Sample [ICPSR #22840]). Respondents were interviewed in their homes using a Computer Assisted Personal Interview (CAPI) survey protocol and asked to complete and return a Self-Administered Questionnaire (SAQ). Afterwards these individuals were eligible for participation in the same research protocol as the national MIDUS 2 sample, including cognitive, daily stress, biomarker, and neuroscience projects.

With support from the National Institute on Aging, a second wave of survey data collection on the Milwaukee sample was begun in 2016. The survey consisted of a 2.5 hour CAPI interview followed by a 45-page mailed SAQ. CAPI survey data was collected for 389 individuals, realizing a 78 percent response rate, adjusted for mortality and other eligibility criteria. Data collection for this follow-up wave largely repeated baseline assessments, with additional questions in selected areas (e.g., economic recession experiences, childhood experience with race, etc.). Following successful completion of the CAPI and SAQ protocols, individuals were eligible for participation in cognitive, daily stress, biomarker, and neuroscience projects.

Midlife in the United States (MIDUS): Psychological Experiences Follow-Up Study, 1998 (ICPSR 2911)

Released/updated on: 2018-03-23
Geographic coverage: United States
Time period: 1998-03-01--1998-09-01
The Midlife in the United States (MIDUS) data collection was a collaborative, interdisciplinary investigation of patterns, predictors, and consequences of midlife development in the areas of physical health, psychological well-being, and social responsibility. This component of the first MIDUS data collection was designed to understand popular metaphors of personal turmoil and change, such as the "midlife crisis," the "change of life," the "empty nest syndrome," and more. The primary objective of the Psychological Experiences Study was to explore how adults perceive psychological change in their lives. The study used questions derived from John Clausen's definition of "turning points" and other sources to collect data on self-perceived psychological changes involving work, important relationships, views about the self and dreams, beliefs about the midlife crisis, and recent major life events and transitions. This study was a random telephone follow-up of 724 respondents of the original MIDUS random-digit-dial sample. Part 1 of this collection consists of the quantitative data obtained from the telephone interviews. Part 2 includes the open-ended responses to selected questions from the telephone interviews.

Time period: 2012-01-01--2013-01-01

In 2012-2013, the MIDUS Milwaukee Refresher study recruited a sample of 508 Milwaukee African American adults, aged 25 to 64, designed to replenish the Midlife Development in the United States (MIDUS 2): Milwaukee African American Sample, 2005-2006 (ICPSR 22840). This sample was also designed to increase the number of racial minorities included in the broader MIDUS study. The MIDUS Milwaukee Refresher survey employed the same assessments (demographic, psycho-social, and physical and mental health) as those assembled on the existing MIDUS sample, but with additional questions about the effect of the economic recession of 2008-09. A sample of African Americans from Milwaukee County, Wisconsin, was stratified by age, gender, and income.

Area probability sampling methods were used to identify potential respondents. Field interviewers screened households to determine if they contained any African American adults. There was additional screening to achieve an appropriate age/gender distribution in a manner similar to what was done for the original MIDUS sample (Midlife in the United States (MIDUS 1), 1995-1996 [ICPSR 2760]). Milwaukee respondents were interviewed in their homes using a 2.5-hour Computer Assisted Personal Interview (CAPI) protocol and afterwards asked to complete a self-administered questionnaire (SAQ). All measures paralleled those used in the larger MIDUS samples. In addition to successful completion of the survey, participants were asked to complete a cognitive assessment by phone. Some respondents were eligible to participate in additional MIDUS projects: daily diary assessments, biomarker assessments, and neuroscience assessments.

Released/updated on: 2025-11-19
Geographic coverage: Milwaukee, United States, Wisconsin
Time period: 2023-01-01--2024-01-01

In 2012-2013, the MIDUS Milwaukee Refresher study recruited a sample of 508 Milwaukee African American adults, aged 25 to 64, designed to replenish the original MIDUS Milwaukee 1 survey that was designed to increase the number of racial minorities in 2005. The MIDUS Milwaukee Refresher survey employed the same comprehensive assessments (demographic, psycho-social, and physical and mental health) as those on the existing MIDUS sample, with additional questions about the effect of the Great Recession in 2008-09.

In 2023-2024, the second wave of survey data was collected from 327 longitudinal Refresher Milwaukee participants, including the questions (1) repeated from the Refresher 1, (2) new impacts of the COVID-19 pandemic replacing the questions related to the Great Recession in the Refresher 1, and (3) the additional questions in selected areas (e.g., AD8, IADL, family history of dementia). This new longitudinal MIDUS Refresher Milwaukee data allow examination of period effects on health and well-being related to the COVID-19 pandemic by comparing the pre-pandemic MIDUS Refresher Milwaukee 1 data with the post-pandemic MIDUS Refresher Milwaukee 2 data. Further, the longitudinal MIDUS Refresher datasets (wave 1 and wave 2) allow investigation of the two major macro-level historic events, the Great Recession and the COVID-19 pandemic, on health and well-being.

National Academy of Sciences-National Research Council Twin Registry (NAS-NRC Twin Registry), 1958-2013 [RESTRICTED] (ICPSR 36234)

Released/updated on: 2020-11-16
Geographic coverage: United States
Time period: 1958-01-01--2013-01-01

In 1958, the Medical Follow-up Agency (MFUA) of the Institute of Medicine began a project to identify twins who had jointly entered military service during World War II. In the end, MFUA identified nearly 16,000 White male twin pairs born 1917-1927 in which both members had served in the military. These twins comprise the National Academy of Sciences-National Research Council World War II Twin Registry (NAS-NRC Twin Registry). This collection represents data from service records, a mailed questionnaire assessing zygosity, and repeating health surveys, including information on education, employment history, and earnings.

There are nine datasets associated with this restricted-use collection:

1) The Administrative dataset includes demographic, zygosity, service history, mortality, and questionnaire participation data;

2) The Service and Other Records dataset contains information collected from service records, physical exam data, cognitive test data, and dental records;

3) The Questionnaire 2 dataset consists of data collected in the first mailed questionnaire sent in 1965 about pain, illnesses, smoking habits, alcohol consumption, and employment;

4) The Questionnaire 3 dataset includes data from the baseline epidemiological questionnaire sent in 1974 about number and sex of children, religious attendance, education, income, and occupation;

5) Questionnaire 7, mailed in 1985, contains similar topics as in Questionnaire 2, and includes data about health conditions such as diabetes, as well as feelings about work and retirement;

6) Questionnaire 8 was mailed in 1998 was the third epidemiologic questionnaire. This dataset is comprised of overlapping topics with Q2 and Q7, and has additional data about feelings, prescription medications, activity levels, the Geriatric Depression Scale, and parental death status;

7) The NEO Personality Inventory dataset includes responses to the NEO Five-Factor Personality Inventory mailed in 2005-2006;

8) The Service and Death Records dataset (VDE access only) contains information about date and place of birth, state at induction, disciplinary measures during service, decorations received during service, indicator for those known to have been POWs, reason for separation from the military, age at death if died over age 90, and cause of death. Some of this information was obtained from the re-read of service records and is thus available only for a subset of 6357 men;

9) Diagnoses dataset (VDE access only) contains data about medical conditions diagnosed between 1935 and 1985 that were abstracted from a variety of medical records over the course of the study. The diagnoses were coded using the International Classification of Disease system (WHO, 2015).
