Alternative Sentencing Policies for Drug Offenders: Evaluating the Effectiveness of Kansas Senate Bill 123, 2001-2010 (ICPSR 30982)
The study examined the first five years of operation of Kansas senate bill 123 (November 2003-November 2008) examining individual-level and system-level outcomes over time and across community corrections districts and judicial actors. The study also assesses the impact of SB 123 on the work routines of criminal justice system actors, examining changes in sentencing and supervision practices and interactions across agencies following the implementation of SB 123.
Individual-level impacts of SB 123 on recidivism rates are assessed using sentencing and revocation data collected by the Kansas Sentencing Commission for drug possessors sentenced in Kansas between November 1, 2001 and October 31, 2008 (Dataset 1). Propensity score matching was used to compare the revocation and reconviction rates of drug possessors sentenced to SB 123 with the recidivism rates of similar individuals sentenced to regular probation (standard supervision by community corrections or court services) (Dataset 2). Supervision and program participation data provided by the Kansas Department of Corrections were used to assess the use of drug treatment services, education and employment services, and sanctions for individuals sentenced to SB 123 or standard community corrections (Dataset 3). These quantitative data were complemented by a set qualitative data derived from interviews with SB 123-eligible offenders (Dataset 4), community corrections managers, and courtroom actors (judges, prosecutors, public defenders) (Dataset 5).

Detroit [Michigan] Neighborhood Health Study, 2008-2013 (ICPSR 37038)
The Detroit Neighborhood Health Study (DNHS) is a prospective, representative longitudinal cohort study of predominantly African American adults living in Detroit, Michigan. The main purpose of the study was to determine the predictive effects of ecological stressors, such as income distribution and residential segregation, on the development of post-traumatic stress disorder (PTSD), substance use, and other psychological and behavioral outcomes. An additional purpose was to study the interrelationships between ecological stressors, exposure to potentially traumatic events (PTEs), PTSD, substance use, and immune function. The study team hypothesized that exposure to ecological stressors would influence the risk of PTE exposure, PTSD, substance use, other psychological outcomes, and the relationships between these factors.
The current collection includes data from all 5 waves of the study. Cohort participants were initially recruited in 2008 with a dual-frame probability design, using telephone numbers obtained from the U.S. Postal Service Delivery Sequence Files as well as a listed-assisted random-digit-dial frame. Individuals without listed landlines or telephones and individuals with only a cell phone listed were invited to participate through a postal mail effort. Participants completed a 40 minute, structured telephone interview annually between 2008-2012 to assess perceptions of participants' neighborhoods, mental and physical health status, social support, exposure to traumatic events, and alcohol and tobacco use. In addition, the study team completed a structured assessment of Detroit's 54 neighborhoods in order to describe the characteristics of respondents' neighborhoods. The assessment included information about the quality of housing exteriors; presence of graffiti, abandoned cars, alcohol and tobacco advertisements, and security warning signs; presence of vacant buildings; and street and traffic noise levels.
All survey participants were offered the opportunity to provide a blood specimen (venipuncture, blood spot, or saliva) for immune and inflammatory marker testing as well as genetic testing of DNA. Participants received an additional $25USD if they elected to give a sample. Informed consent was obtained at the beginning of each interview and again at specimen collection. However, these specimens are not included as part of this data collection.

The Early Steps Multisite (ESM) Study is a randomized controlled trial testing the efficacy of the early childhood version of the Family Check-Up intervention. The enclosed data file includes home-based assessments carried out at child ages 2, 3, 4, 5, 7.5, 8.5, 9.5, and 10.5 involving 731 families from three distinct communities in the United States: Pittsburgh, PA (urban), Eugene, OR (suburban), and in and outside Charlottesville, VA (rural). Assessments include questionnaires and interviews with primary caregivers (i.e., typically mothers) and alternative caregivers (fathers, grandparents, and other child caregivers) about child behavior, sociodemographic and family risk, parent well-being and support, coupled with observations of developmentally-tailored parent-child interaction tasks (e.g., teaching, clean-up, and meal preparation tasks at ages 2-5, discussion tasks at ages 7.5 and 9.5). Teacher reports on multiple domains of child behavior were obtained beginning at age 7.5 through age 10.5, and youth reports on their own adjustment beginning at child age 8.5. Direct testing of children's academic achievement was administered at child ages 5, 7.5, and 8.5 using scales from the Woodcock-Johnson.

The Future of Families and Child Wellbeing Study (FFCWS), Public Use, United States, 1998-2024 (ICPSR 31622)
The Future of Families and Child Wellbeing Study (FFCWS, formerly known as the Fragile Families and Child Wellbeing Study) follows a cohort of nearly 5,000 children born in large, U.S. cities between 1998 and 2000. The study oversampled births to unmarried couples; and, when weighted, the data are representative of births in large U.S. cities at the turn of the century. The FFCWS was originally designed to address four questions of great interest to researchers and policy makers:
- What are the conditions and capabilities of unmarried parents, especially fathers?
- What is the nature of the relationships between unmarried parents?
- How do children born into these families fare?
- How do policies and environmental conditions affect families and children?
The FFCWS consists of interviews with mothers, fathers, and/or primary caregivers at birth and again when children are ages 1, 3, 5, 9, 15, and 22. The parent interviews collected information on attitudes, relationships, parenting behavior, demographic characteristics, health (mental and physical), economic and employment status, neighborhood characteristics, and program participation. Beginning at age 9, children were interviewed directly (either during the home visit or on the telephone). The direct child interviews collected data on family relationships, home routines, schools, peers, and physical and mental health, as well as health behaviors.
A collaborative study of the FFCWS, the In-Home Longitudinal Study of Pre-School Aged Children (In-Home Study) collected data from a subset of the FFCWS Core respondents at the Year 3 and 5 follow-ups to ask how parental resources in the form of parental presence or absence, time, and money influence children under the age of 5. The In-Home Study collected information on a variety of domains of the child's environment, including: the physical environment (quality of housing, nutrition and food security, health care, adequacy of clothing and supervision) and parenting (parental discipline, parental attachment, and cognitive stimulation). In addition, the In-Home Study also collected information on several important child outcomes, including anthropometrics, child behaviors, and cognitive ability. This information was collected through interviews with the child's primary caregiver, and direct observation of the child's home environment and the child's interactions with his or her caregiver.
Similar activities were conducted during the Year 9 follow-up. At the Year 15 follow-up, a condensed set of home visit activities were conducted with a subsample of approximately 1,000 teens. Teens who participated in the In-Home Study were also invited to participate in a Sleep Study and were asked to wear an accelerometer on their non-dominant wrist for seven consecutive days to track their sleep (Sleep Actigraphy Data) and that day's behaviors and mood (Daily Sleep Actigraphy and Diary Survey Data).
An additional collaborative study collected data from the child care provider (Year 3) and teacher (Years 9 and 15) through mail-based surveys. Saliva samples were collected at Year 9 and 15 (Biomarker file and Polygenic Scores). The Study of Adolescent Neural Development (SAND) COVID Study began data collection in May 2020 following the onset of the COVID-19 pandemic. It included online surveys with the young adult and their primary caregiver.
The FFCWS began its seventh wave of data collection in October 2020, around the focal child's 22nd birthday. Data collection and interviews continued through January 2024. The Year 22 wave included a young adult (YA) survey with the original focal child and a primary caregiver (PCG) survey. Data were also collected on the children of the original focal child (referred to as Generation 3, or G3).
In 2017, the FFCWS team announced the Fragile Families (FF) Challenge, a collaborative effort in which participants were tasked with using machine learning methods and FFCWS data (Baseline to Year 9) to build a model that would predict six key outcomes at Year 15. Materials used in the FF Challenge have been archived in this collection.

Individualized Assessment and Treatment for Marijuana Dependence: Treatment Mechanisms, United States, 2013-2016 (ICPSR 39044)
Marijuana is the most commonly used illicit drug in the US, but treatment for marijuana dependence is not fully effective. The most effective treatments to date have employed motivational enhancement (MET) plus cognitive-behavioral coping skills treatment (CB) and contingency management (CM) for abstinence. This study was intended to deliver a treatment to enhance coping and self-efficacy to improve marijuana outcomes in the long term. Researchers are explored the idea that more tailored teaching of coping skills may result in improved outcomes for marijuana-dependence than those seen thus far. The Individualized Assessment and Treatment Program (IATP) for marijuana dependent patients employed experience sampling (ES) to determine the strengths and weaknesses of each patient in drug-use situations so that treatment could be tailored accordingly.
Participants were 198 men and women meeting criteria for marijuana dependence and randomly assigned to 9 sessions of treatment in one of 4 treatment conditions: Standardized MET plus CB (SMET-CB); SMET+ CM (SMET-CB-CM); IATP; or IATP + CM (IATP-CM). Patients in all treatments engaged in ES via cell-phone for two weeks prior to treatment, for a weekly period during treatment, for another week after treatment has ended, and for two weekly periods at months 8 and 14. In the IATP conditions, the information gathered from the pretreatment and during-treatment ES periods provided data for a functional analysis of patients' drug use and urges to use. Therapists used the information to address specific cognitions, affects, and behaviors that were adaptive and maladaptive, and tailored a specific coping skills program with the patient. During-treatment experience sampling allowed monitoring of the treatment goals and procedures, making the treatment adaptive. In the SMET-CB conditions the experience sampling data were not used in therapy, but still provides in-vivo measures of drug use and coping skills.
It was hypothesized that IATP conditions would yield significantly better coping skills acquisition than SMET-CB conditions, both at posttreatment and at extended follow-ups, and that change in coping skills would predict better outcomes for the IATP conditions. It was further predicted that the addition of CM to both IATP and SMET-CB would enhance short-term and long-term outcomes. The results would have implications for improved tailoring of treatment to patients' strength and deficits, and for the validity of the training of coping skills for cannabis relapse prevention. The data collected will shed light on the ways in which patients in treatment use coping skills in real-time contexts. Finally, the use of repeated ES periods will allow researchers to determine how treatment impacts thoughts, feelings and behaviors, and how these in turn affect outcome in the long and short term.
Integrated Public Health Surveys, 2010-2011 (ICPSR 33822)
This collection comprises a single data file which was produced as part of the data harmonization efforts of the Robert Wood Johnson Foundation and the United States Centers for Disease Control and Prevention. The file contains merged data from five sources:
2010 National Profile of Local Health Departments, a survey of local health departments conducted by the National Association of County and City Health Officials (NACCHO).
2011 National Profile Survey of Local Boards of Health, a survey of local boards of health conducted by the National Association of Local Boards of Health (NALBOH).
2010 State and Territorial Public Health Survey, a survey of state and United States territory health departments conducted by the Association of State and Territorial Health Officials (ASTHO).
2011 County Health Rankings, a compilation of county-level health measures and within-state county health rankings produced by the University of Wisconsin Population Health Institute.
2010 Census Demographic Profile Summary File, a series of tables with housing and population data from the 2010 Census.
Produced by matching data from the last four sources to the NACCHO data, the data file contains one case for each of the 2,107 local health departments (LHD) that responded to the NACCHO survey. Each LHD's record in the file includes the ASTHO data for its state health department and the NALBOH data for its local board of health (LBH), if it had a LBH and the LBH responded to the NALBOH survey. (If a LHD had multiple LBHs, then the first one in the NALBOH data was matched to the LHD). In addition, county (or county equivalent)-level data from the County Health Rankings and Census Demographic Profile Summary File were matched to the records of the 1,535 LHDs represented in the data file with a jurisdiction covering a single county or county equivalent.
The Iowa Adoption Studies, 1975-2008 (ICPSR 34369)
The Iowa Adoption Studies were conducted between 1975 and 2008. The group of studies consist of 5 independent waves of data collection each of which examined genetic (biological) and environmental influences on psychopathology. The adoption paradigm allowed separation of genetic and environmental influences on behavior, as well as joint influences due to gene x environment interaction. Adoptees were interviewed about lifetime psychopathology including substance abuse and dependence, antisocial personality, and mood disorders. A follow-up study was conducted from 2000-2004 that recruited all previous participants and natural offspring of the adoptive parents when available. Standardized psychiatric assessments were administered along with measures of personality disorders and traits, retrospective reports on childhood experiences with adoptive parents, and current symptomatology. An extensive neurocognitive assessment was conducted on a subset of participants who had standardized school achievement scores. The goal of this last wave of assessment was to evaluate the influence of substance use on mid-life cognition and health.
The respondents were assessed using a number of different surveys over the study period. The following describes the notable variables as well as descriptions of the surveys included in the dataset.
The first variables in the dataset identify sibling pairs and provides data on whether the respondents' biological parents suffered from mental health or substance abuse issues. Next birth records are provided that give basic information about the health of the person when he or she was born. This information is followed by the survey results of "The Schedule for Nonadaptive and Adaptive Personality" (SNAP) as well as variables that reflect the diagnosis of personality disorders and nonadaptive personality traits based on the SNAP survey responses.
The next section includes responses from "The Iowa Personality Disorder Screen," a quick personality disorder screen developed in 1999 intended for use in clinical and research settings.
Next, responses to Pearson Assessments "Brief symptoms inventory" are included as well as the scores calculated based on these survey responses. The results of this survey assess the mental state of the patient including scales on Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic Anxiety, Paranoid Ideation and Psychoticism.
The respondents also completed the "Buss-Durkee Hostility Questionnaire" and were assessed on measure regarding the following hostility traits: negativism, resentment, indirect hostility, assault, suspicion, irritability and verbal hostility.
Reponses to the "The Social Provisions Scale" survey are also included. The purpose of this survey is to assess the relationship the respondents have to other people. The 6 social provisions assessed include: guidance, reliable alliance, reassurance of worth, attachment, social integration, and opportunity for nurturance.
"The Parental Bonding Instrument" instrument was utilized to assess the respondents' relationships to their mothers and fathers.
A series of cognitive tests were administered to respondents. ICPSR is unable to provide the survey instruments used in the cognitive test due to copy write issues. These tests include:
Controlled Oral Word Association Test (COWAT)
North American Adult Reading Test (NAART)
Rey Figure and Rey Complex Figure Test and Recognition Trial (RCFT)
Shipley Institute of Living Scale (SILS)
Stroop Color and Word Test (SCWT)
Tower of Hanoi (TofH)
Comprehensive Trailmaking Test (CTMT)
Weschler Adult Intelligence Test (WAIS)
Weschler Memory Test (WMS)
The dataset also includes respondents' results of the Comprehensive Performance Test (CPT) and the Iowa Gambling Task (IGT)
Scores from the "Iowa Test of Basic Skills," a test of academic achievement that evaluates students knowledge in subjects including, mathematics, reading comprehension, and science, are included in the dataset. Respondents are evaluated in grades 4, 8 and 11.
The final section of the dataset includes two waves of the "Semi Structured Assessment for the Genetics of Alcoholism," a survey intended to assess the physical, psychological, and social manifestations of alcohol abuse. These survey responses make up the bulk of the dataset and include variables on a variety of topics including: demographics, medical history, substance use, eating disorders, depression, dysthymia, mania, ASP, suicide, PTSD, generalized anxiety disorder, OCD, social phobia, agoraphobia, panic disorder, home environment, gambling, and ADHD. Substances use investigated includes alcohol, tobacco, marijuana, sedatives, stimulants, cocaine, opiates, solvents, hallucinogens, and other drugs.
This dataset includes 934 cases and 9,370 variables.
Iowa Youth and Families Project, 1989-1992 (ICPSR 26721)
This data collection contains the first four waves of the Iowa Youth and Families Project (IYFP), conducted in 1989, 1990, 1991, and 1992. The Iowa Youth and Families Project was developed from an initial sample of 451 7th graders from two-parent families in rural Iowa. The study was merged with the Iowa Single Parent Project (ISPP) to form the Iowa Family Transitions Project in 1994, when the target youth were seniors in high school. Survey data were collected from the target child (7th grader), a sibling within four years of age of the target child, and both parents. Field interviewers visited families at their homes on several occasions to administer questionnaires and videotape interaction tasks including family discussion tasks, family problem-solving tasks, sibling interaction tasks, and marital interaction tasks.
The Household Data files contain information about the family's financial situation, involvement in farming, and demographic information about household members.
The Parent and the Child Survey Data files contain responses to survey questions about the quality and stability of family relationships, emotional, physical, and behavioral problems of individual family members, parent-child conflict, family problem-solving skills, social and financial support from outside the home, traumatic life experiences, alcohol, drug, and tobacco use, and opinions on topics such as abortion, parenting, and gender roles. In addition, the Child Survey Data files include responses collected from the target child and his or her sibling in the study about experiences with puberty, dating, sexual activity, and risk-taking behavior.
The Problem-Solving Data files contain survey data collected from respondents about the family interactions tasks.
The Observational Data files contain the interviewers' observations collected during these tasks.
Demographic variables include sex, age, employment status, occupation, income, home ownership, religious preference, frequency of religious attendance, as well as the ages and sex of all household members and their relationship to the head of household. Demographic information collected on the parents also includes their birth order within their family, the ages and political philosophy of their parents, the sex, age, education level, and occupation of their siblings, and the country of origin of their ancestors.

Midlife in the United States (MIDUS 1), 1995-1996 (ICPSR 2760)
The Midlife in the United States (MIDUS) is a collaborative, interdisciplinary investigation of patterns, predictors, and consequences of midlife development in the areas of physical health, psychological well-being, and social responsibility. A description of the study and findings from it are available at http://www.midus.wisc.edu.
The first wave of the MIDUS study (MIDUS 1 or M1) collected survey data from a total of 7,108 participants. The baseline sample was comprised of individuals from four subsamples: (1) a national RDD (random digit dialing) sample (n=3,487); (2) oversamples from five metropolitan areas in the U.S. (n=757); (3) siblings of individuals from the RDD sample (n=950); and (4) a national RDD sample of twin pairs (n=1,914). All eligible participants were non-institutionalized, English-speaking adults in the coterminous United States, aged 25 to 74.
Data from the samples were collected primarily in 1995/96. The survey (Project 1) dataset contains responses from a 30-minute Phone interview and two 50-page Self-Administered Questionnaire (SAQ) instruments. Of the 7,108 respondents who completed the Phone interview, 6,325 also completed the SAQ.
This updated version of the study is comprised of three primary datasets:
Dataset 1, Main, Siblings, and Twin Data, contains responses from the main survey of 7,108 respondents. Respondents were asked to provide extensive information on their physical and mental health throughout their adult lives, and to assess the ways in which their lifestyles, including relationships and work-related demands, contributed to the conditions experienced. Those queried were asked to describe their histories of physical ailments, including heart-related conditions and cancer, as well as the treatment and/or lifestyle changes they went through as a result. A series of questions addressed alcohol, tobacco, and illegal drug use, and focused on history of use, regularity of use, attempts to quit, and how the use of those substances affected respondents' physical and mental well-being. Additional questions addressed respondents' sense of control over their health, their awareness of changes in their medical conditions, commitment to regular exercise and a healthy diet, experience with menopause, the decision-making process used to deal with health concerns, experiences with nontraditional remedies or therapies, and history of attending support groups. Respondents were asked to compare their overall well-being with that of their peers and to describe social, physical, and emotional characteristics typical of adults in their 20's, 40's, and 60's. Information on the work histories of respondents and their significant others was also elicited, with items covering the nature of their occupations, work-related physical and emotional demands, and how their personal health had correlated to their jobs. An additional series of questions focusing on childhood queried respondents regarding the presence/absence of their parents, religion, rules/punishments, love/affection, physical/verbal abuse, and the quality of their relationships with their parents and siblings. Respondents were also asked to consider their personal feelings of accomplishment, desire to learn, sense of control over their lives, interests, and hopes for the future.
The Datasets previously numbered 2 and 3 have been removed to avoid redundancies, and all datasets have been renumbered. Please refer to the readme file.
Dataset 2, Twin Screener Data, provides the first national sample of twin pairs ascertained randomly via the telephone.
Dataset 3, Coded Text Responses, describes how open-ended textual responses in the MIDUS 1 Computer-Assisted Telephone Interview (CATI) and Self-Administered Questionnaire (SAQ) were transformed into categorical numeric codes. These codes are included in a stand-alone dataset containing only those cases (N=3,950) that contained text data in their responses.
Online Analysis Only: Datasets 1, 2, and 3 were merged together by the SU_ID variable to form "Merged Data with Weights (Online Analysis Only)" (Dataset 4) for online analysis capabilities.
MIDUS also maintains a Colectica portal, which allows users to interact with variables across waves and create customized subsets. Registration is required.
Midlife in the United States (MIDUS 2), 2004-2006 (ICPSR 4652)
In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of 7,108 Americans aged 25 to 74 (MIDLIFE IN THE UNITED STATES (MIDUS), 1995-1996 [ICPSR 2760]). The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health. The study was innovative for its broad scientific scope, its diverse samples (which included twins and the siblings of main sample respondents), and its creative use of in-depth assessments in key areas (e.g., daily stress and cognitive functioning). A description of the study and findings from it are available at http://www.midus.wisc.edu. With support from the National Institute on Aging, a longitudinal follow-up of the original MIDUS samples: core sample (N = 3,487), metropolitan over-samples (N = 757), twins (N = 925 complete pairs), and siblings (N = 950), was conducted in 2004-2006. Guiding hypotheses for it, at the most general level, were that behavioral and psychosocial factors are consequential for physical and mental health. MIDUS 2 respondents were aged 35 to 86. Data collection largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas (e.g., cognitive functioning, optimism and coping, stressful life events, and caregiving). To add refinements to MIDUS 2, an African American sample (N = 592) was recruited from Milwaukee, Wisconsin, who participated in a personal interview and completed a questionnaire paralleling the above assessments. Survey data for the Milwaukee sample are available in a separate project [ICPSR 22840]. Also administered was a modified form of the mail questionnaire, via telephone, to respondents who did not complete a self-administered questionnaire.

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.
Midlife in the United States (MIDUS Refresher 1), 2011-2014 (ICPSR 36532)
In 2011-2014, the MIDUS Refresher study recruited a national probability sample of 3,577 adults, aged 25 to 74, designed to replenish the original MIDUS 1 baseline cohort and paralleling the five decadal age groups of the MIDUS 1 baseline survey [ICPSR 2760]. The MIDUS Refresher survey employed the same comprehensive assessments as those assembled on the existing MIDUS sample, but with additional questions about the effect of the economic recession of 2008-09.
The MIDUS Refresher collection is split into two datasets: Aggregate Data and Coded Text Data. The Coded Text Dataset provides coded responses to open-ended question items in the Aggregate Dataset. The survey data collection (Project 1) [MIDUS, ICPSR 2760] consisted of a 30-minute phone interview followed by two 50-page mailed self-administered questionnaires. Survey data were collected on demographic, psycho-social, and physical and mental health information. This new crosssectional MIDUS sample allows the examination of period effects on health (mental and physical) related to the economic recession by comparing the pre-recession MIDUS 1 sample with the post-recession MIDUS Refresher sample. A further objective of the MIDUS Refresher sample was to strengthen cross-project analyses in MIDUS by increasing the sample sizes available for testing hypotheses dealing with the interplay of key factors (e.g., socioeconomic status, gender, psychosocial factors, biological factors) in mid- and laterlife health. To that end, the MIDUS Refresher sample followed the same multi-disciplinary protocol established in the main MIDUS sample, in that after completing the survey protocol respondents were asked to complete a cognitive assessment by phone (Project 3) [MIDUS 3, ICPSR 36346] and later became eligible to participate in daily diary assessments (Project 2) [MIDUS 2, ICPSR 4652] biomarker assessments (Project 4) [MIDUS 2: Biomarker Project, ICPSR 29282] and neuroscience assessments (Project 5) [MIDUS 2: Neuroscience Project, ICPSR 28683].
The MIDUS Refresher was funded by the National Institute on Aging as two separate but related efforts: The MIDUS Refresher younger decades (MRY), was fielded in November, 2011, and recruited over 2,100 new participants aged 25 to 54; Funding was later added for the MIDUS Refresher older decades (MRO), which was fielded in June, 2013 and recruited over 1,400 new participants aged 55 to 74.
Demographic variables include age, sex, gender, race, religion, and marital status.

Monitoring the Future: Base Year & Follow-Up Core Panel Data, Ages 18-30, United States, 1976-2021 [Restricted-Use] (ICPSR 39223)
The Monitoring the Future (MTF) project is a long-term epidemiologic and etiologic study of substance use among youth and adults in the United States. It is conducted at the University of Michigan's Institute for Social Research and is funded by a series of investigator-initiated research grants from the National Institute on Drug Abuse.
The MTF panel study consists of six different survey forms (five forms from 1976-1988), and each survey contains a "core" set of questions about demographics and substance use. This study contains the "core" data for these questions compiled across all survey forms and years in which they are included for the longitudinal panel participants. Each record in the core panel dataset includes the respondent's data for their base year (BY) 12th grade survey (modal age 18) and their young adult follow-up FU surveys (modal ages 19-30).
