Adolescent Health and Development in Context (AHDC) Study, Franklin County, Ohio, Wave 1, 2014-2016 (ICPSR 39045)
Released/updated on: 2024-07-23
Geographic coverage: United States, Columbus (Ohio), Ohio
Time period: 2014-01-01--2016-12-31
The overarching objective of the Adolescent Health and Development in Context (AHDC) Project is to collect multilevel, multi-contextual data on a large sample of 1,405 youth ages 11 to 17 years in Franklin County, Ohio. The study emphasizes the interplay of social, psychological, and biological processes in shaping youth developmental outcomes such as risk behavior and victimization, mental and physical health, and educational outcomes. The study employs a prospective cohort design in which the data on youth and caregivers were collected at two time-points, approximately one year apart. The Wave 1 field period began in spring 2014 and was completed in summer 2016. Wave 2 was conducted between January and December 2016. Within each wave, participant data were collected over a weeklong period. An Entrance Survey with both a focal youth and his or her caregiver was followed by a seven-day smartphone-based Global Positioning System (GPS) tracking and EMA data collection period (EMA Week), and a final Exit Survey at the end of the week.

Daily Experience in Adolescence and Biomarkers of Early Risk for Adult Health (ICPSR 35952)
Released/updated on: 2015-06-05
Geographic coverage: United States
This project conducts a 3-wave longitudinal study of adolescents and their caregivers from Mexican, Chinese, and European backgrounds in order to assess the impact of daily experience on biological indicators of early risk for adult health. It includes intensive behavioral assessments and detailed biological markers of health risk from both adolescents and their parents. Approximately 540 pairs of adolescents and their primary caregivers (180 from each ethnic group) are assessed when the adolescents are approximately 15-16, 17-18, and 19-20 years old. Each year, both adolescents and caregivers participate in interviews that include measures of global social factors and potential protective factors. Participants report daily experiences using a nightly diary checklist for 9 consecutive days. Salivary cortisol is obtained at 4 time points each day for 4 of these days in order to analyze HPA activity, and participants wear wrist actigraphs for the same 4 days to measure objective sleep behaviors. Blood pressure, BMI, and waist/hip ratio are assessed, and dried blood spots are obtained for the assessment of c-reactive-protein (CRP), cholesterol, and high density lipoproteins (HDL). Finally, peripheral blood samples are provided by a subsample of 120 families for the assessment of plasma interleukin-6 (IL-6), a pro-inflammatory cytokine, and for gene expression analyses of molecular signaling pathways driving inflammatory biology.

Do Older Adults Know Their Spouses' End-of-Life Treatment Preferences? (ICPSR 25701)
Released/updated on: 2009-06-23
Geographic coverage: United States
When terminally ill patients become mentally incapacitated, their surrogates often make treatment decisions in collaboration with health care providers. The authors examined how surrogates' errors in reporting their spouses' preferences are affected by their gender, status as durable power of attorney for health care (DPAHC), whether they and their spouses discussed end-of-life preferences, and their spouses' health status. Structural equation models were applied to data from married couples in their mid-60s from the 2004 wave of the Wisconsin Longitudinal Study. Surrogates reported their spouses' preferences incorrectly 13 percent and 26 percent of the time in end-of-life scenarios involving cognitive impairment and physical pain, respectively. Surrogates projected their own preferences onto their spouses'. Similar patterns emerged regardless of surrogate gender and status as DPAHC, marital discussions about end-of-life preferences, or spousal health status. Implications for the process of surrogate decision-making and for future research are discussed.

Longitudinal Study of Generations, 1971, 1985, 1988, 1991, 1994, 1997: [California] (ICPSR 4076)
Released/updated on: 2005-02-25
Geographic coverage: United States, Los Angeles, California
The Longitudinal Study of Generations (LSOG), initiated in 1971, began as a survey of intergenerational relations among 300 three-generation California families: grandparents (then in their sixties), middle-aged parents (then in their early forties), and grandchildren (then aged 15 to 26). The study broadened in 1991 and now includes a fourth generation, the great-grandchildren of these same families. The LSOG, with a fully elaborated generation-sequential design, allows comparisons of sets of aging parents and children at the same stage of life but during different historical periods. These comparisons make possible the investigation of the effects of social change on inter-generational solidarity or conflict across 35 years and four generations, as well as effects of social change on the ability of families to buffer stressful life transitions (aging, divorce and remarriage, higher female labor force participation, changes in work and the economy, and possible weakening of family norms of obligation), and the effects of social change on the transmission of values, resources, and behaviors across generations. The study also examines how intergenerational relationships influence individuals' well-being as they transition across the life course from early, to middle, to late adulthood. The LSOG contains information on family structure, household composition, affectual solidarity and conflict, values, attitudes, behaviors, role importance, marital relationships, health and fitness, mental health and well-being, caregiving, leisure activities, and life events and concerns. Demographic variables include age, sex, income, employment status, marital status, socioeconomic history, education, religion, ethnicity, and military service.

Midlife in the United States (MIDUS 3), 2013-2014 (ICPSR 36346)
Released/updated on: 2019-04-30
Geographic coverage: Contiguous United States
Time period: 2013-05-01--2014-11-30
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.

National Long-Term Care Survey: 1982, 1984, 1989, 1994, 1999, and 2004 (ICPSR 9681)
Released/updated on: 2010-06-21
Geographic coverage: United States
Time period: 1982-01-01--1982-12-31, 1984-01-01--1984-12-31, 1989-01-01--1989-12-31, 1994-01-01--1994-12-31, 1999-01-01--1999-12-31, 2004-01-01--2004-12-31
The National Long-Term Care Survey (NLTCS) has completed six waves, nominally at five-year intervals, 1982, 1984, 1989, 1994, 1999, and 2004. The NLTCS is a nationally-representative sample both of the community and of institutionalized populations and is longitudinal in that sample persons join the survey once they reach 65 years of age and stay in the survey until they either die or are lost to follow-up. At each wave, a screener questionnaire is administered to the sample which divides the sample into three parts: the non-disabled (frequently called screen-outs), the disabled but living in the community, and the disabled living in an institution. About 5,000 people die between waves and are replaced by a sample of about that size of people who have become age 65 since the prior wave. Because of budget considerations it usually has not been possible to continue the entire non-disabled sample into the next wave. Instead a sample of the non-disabled is drawn to keep the total sample size for a wave at about 20,000. One of the interesting and useful features of the NLTCS is that data are collected on help that the sample person receives from informal caregivers.
The NLTCS is a very data-rich resource with many components, including disability measures, medical conditions, attained education levels, and income. Numerous papers have used it as a source of data addressing a wide variety of topics related to aging and disability.
Ancillary surveys have been added to measure other characteristics of the 65 and older population, to include a Caregiver Survey to acquire data on informal caregivers themselves (done in 1989, 1999, and 2004) and Next-of-Kin (NOK) surveys administered to sample persons who had died between 1982 and 1984 and again between 1994 and 1999. The sample has been frequently supplemented to compensate for low representation in some survey components, in particular the 75 years and older and 95 years and older components. In 1999 physical specimens were drawn from a sample of persons who responded to the survey. These physical specimens (blood where possible, alternatively a buccal wash) are subject to a genetic analysis and, in the case of blood, to a panel of proteins believed to be particularly important to health.

Project on Human Development in Chicago Neighborhoods (PHDCN): Addendum (Primary Caregiver), Wave 3, 2000-2002 (ICPSR 13670)
Released/updated on: 2007-03-02
Geographic coverage: United States, Chicago, Illinois
Time period: 2000-01-01--2002-12-31
The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. For primary caregivers included in Wave 3 but not in Wave 2, an addendum interview was administered consisting of measures or portions of measures from the Wave 2 interview. This included questions from PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): DEMOGRAPHIC FILE, WAVE 2, 1997-2000 (ICPSR 13609), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): MY CHILD'S EXPOSURE TO VIOLENCE, WAVE 2, 1997-2000 (ICPSR 13619), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): FAMILY SUICIDE INTERVIEW, WAVE 2, 1997-2000 (ICPSR 13623), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): HOUSEHOLD COMPOSITION, WAVE 2, 1997-2000 (ICPSR 13628), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): HEALTH SCREEN, WAVE 2, 1997-2000 (ICPSR 13629), and PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): PRENATAL AND EARLY HEALTH, WAVE 2, 1997-2000 (ICPSR 13644).

The CBCL protocol, administered to parents or primary caregivers, was first developed by Thomas M. Achenbach and has been one of the most widely-used standardized measures in child psychology for evaluating maladaptive behavioral and emotional problems in preschool subjects aged 2 to 3 or in subjects between the ages of 4 and 18. One version of the CBCL was administered to primary caregivers of subjects belonging to Cohort 0, while another version was administered to primary caregivers of subjects belonging to Cohorts 3-15 of the Longitudinal Cohort Study. Both versions assessed internalizing (i.e., anxious, depressive, and overcontrolled) and externalizing (i.e., aggressive, hyperactive, noncompliant, and undercontrolled) behaviors. Several subareas were measured including social withdrawal, somatic complaints, anxiety and depression, destructive behavior, social problems, thought problems, attention problems, aggressive behavior, and delinquent behaviors. The Wave 2 versions of the instrument contained a subset of questions asked in the Wave 1 versions. Each of the questions asked in Wave 2 was also asked in Wave 1.

The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One such measure was the Child Care Interview. It was administered to subjects' primary caregivers (PCs) in Cohort 0. It included questions on the structure of child care arrangements, the flexibility and stability of this arrangement, and other questions related to child care. It also asked some questions similar in nature to those asked in PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): SCHOOL AND DAY CARE SCREEN, WAVE 2, 1997-2000 (ICPSR 13653).

Subjects were given a drawing of a circle and then asked to draw a circle, themselves, staying between lines on a sheet of paper given to them. Three different trials were administered. The initial trial served as a baseline. For the second trial, the subject was asked to draw the circle as quickly as possible, and for the third trial the subject was asked to draw the circle as slowly as possible.

One such was the Conflict Tactics Scale for Parent and Child (CTSS). The CTSS, administered to the primary caregiver (PC) of subjects belonging to Cohorts 0, 3, 6, and 9, measured psychological and physical maltreatment and neglect of children by their PC or any other adult family or household member, as well as nonviolent modes of discipline. The CTSS also measured the extent to which an adult carried out specific acts of physical and psychological aggression, regardless of whether the child was injured. This Wave 3 study was modified from the Wave 1 parent-child version of the Conflict Tactics Scale used in PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): CONFLICT TACTICS SCALE FOR PARENT AND CHILD, WAVE 1, 1994-1997 (ICPSR 13584).

Buss and Robert Plomin, was designed to evaluate subjects based on four temperaments (emotionality, activity, sociability, and impulsivity). For the purposes of the PHDCN Longitudinal Cohort Study, the EASI Temperament Survey was administered both to subjects and primary caregivers (PC). The young adults comprising cohort 18 completed the EASI Temperament Survey as a self-report inventory, while the primary caregivers of children belonging to cohorts 3 through 15 completed the EASI Temperament measure as a parental ratings survey. Respondents were asked to determine how accurately the behaviors or personality traits mentioned, characterized the subject in question, either themselves or their child. The responses to the EASI measure were used to evaluate the subjects' various social tendencies, emotional characteristics, and personality traits.

The Employment and Income Interview was administered to the subjects' primary caregivers for Cohorts 0, 3, 6, 9, 12, and 15 and to the subjects themselves for Cohort 18. The Employment and Income Interview was developed specifically for the PHDCN Longitudinal Cohort Study with the intent of combining the employment and income data obtained with educational status data to create socioeconomic stratifications for the respondents. The Employment and Income Interview sought to obtain data describing the respondent's current or most recent employment and that of his or her partner. The Employment and Income Interview also sought information regarding primary income and additional sources of income as well total working hours, proximity to work, and means of transportation to work for both the respondent and his or her partner.

One of these measures was the Family Environment Scale (FES). The FES was designed to assess the interpersonal relationships and the overall social environment within the family. The FES captures the perception of the family's functioning from one of its own members. In the case of the PHDCN Longitudinal Cohort Study, the respondents who completed the FES were the primary caregivers for cohorts 0-15 and the subjects composing cohort 18. The FES specifically sought to quantify three dimensions of the family environment: interpersonal relationships, directions of personal growth, and basic organization and structure. In addition to acting as a self-report measuring the family environment, the FES was also used as an instrument to observe the effect of the family environment on the individual subjects. Three scales (Conflict, Control, and Moral-Religious Emphasis) from the Family Environment Scale were used in this questionnaire to further evaluate the functioning of the family.

One such measure was the Family Legal Update (Young Adult). It was administered to subjects in Cohorts 15 and 18. It included questions designed to ascertain any family member's involvement with the law in the past year. It is related to PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): FAMILY MENTAL HEALTH AND LEGAL HISTORY, WAVE 1, 1994-1997 (ICPSR 13591) and PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): FAMILY LEGAL UPDATE, WAVE 2, 1997-2000 (ICPSR 13622). It is also very similar in nature to PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): FAMILY LEGAL UPDATE, WAVE 3, 2000-2002 (ICPSR 13703).

Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One such measure was the Gift Wrap instrument. It was administered to subjects in Cohort 0 and was designed to observe the impulsivity and restraint of the subject. A research assistant (RA) was provided with a previously wrapped gift for the subject along with other wrapping supplies. The RA informed the subject that he/she had a gift for the subject but that the gift needed to be wrapped so it would be a surprise. The RA then asked the subject not to look and positioned the subject so that the subject was facing away from the RA. The RA then stood approximately three feet behind the subject and pretended to wrap the gift by crinkling and shaking the wrapping supplies. The RA observed the subject in this manner for 60 seconds and coded the subject's reaction to the gift wrapping noises. After the allotted time, the subject was presented with the gift that had previously been wrapped.
