This five-year Hybrid Type 1 Effectiveness-Implementation Randomized Control Trial (RCT) compared two models of linking and retaining individuals recently released from justice involvement to the continuum of community-based HIV and Opioid Use Disorder (OUD) prevention and treatment service cascades of care. A significant innovation of this RCT was that it was delivered within four communities where coalition infrastructures have been established as part of the Justice Community Opioid Innovation Network (JCOIN) studies, a National Institute on Drug Abuse (NIDA)-funded Cooperative Agreement initiative to mitigate the impact criminal justice (CJ)-involved individuals with OUD are having on local communities, and the investigators were able to build on that existing infrastructure. Specifically, 601 CJ-involved individuals were recruited across two Connecticut (New London/Middlesex Counties and Windham/Tolland/New Haven/Hartford Counties) & two Texas (Dallas and Tarrant Counties) high risk communities. HIV status will be assessed via rapid testing at initial point of contact. Participants were randomized to receive at post-release either: a) a Patient Navigator (PN) system for care, wherein navigators assisted linking study participants to appropriate community service providers (e.g., OUD/SUD treatment including medication for opioid use disorder (MOUD), and Hepatitis C virus (HCV) testing and treatment); those not living with HIV were provided access to pre-exposure prophylaxis (PrEP) services, and those living with HIV received assistance with gaining initial or continued access to antiretroviral therapy (ART) services, or b) services delivered via a Mobile Health Unit (MHU) within the participants' community where participants received PrEP/ART, MOUD, and harm reduction services on the MHU or assistance from a community health worker (CHW) in linking to appropriate community-based OUD and other medical and behavioral health providers. The interventions lasted for six months post-release from custody. The focus of this study was the randomized controlled trial.

This multi-method, exploratory study investigated the practices, strategies, and tactics used by police to respond to people experiencing homelessness. Researchers utilized Open Source Social Media Data to document police responses to people experiencing homelessness across 1,004 geographically and jurisdictionally diverse United States police departments, developing an inventory and typology of policing responses. These open-source data were supplemented by coded Legal Case Data, drawn from publicly available legal case records for cases related to police department responses to homelessness, and Agency Policy Data, reporting all police department policies related to homelessness and homeless individuals. Researchers also completed in-depth case studies using observational and survey data collected at six site visits with police departments across the United States. The resulting Social Network Survey Data describe relationships between the homeless outreach team (HOT) at each site, their parent agencies, and community partners. These data are included as DS4 and DS5 in the current data release, alongside the Open Source Social Media Data (DS1), Legal Case Data (DS2), and Agency Policy Data (DS3).

The National Policing Institute (NPI) conducted a three-part study to examine policies, practices, knowledge, and outcomes in eyewitness identification. The two main eyewitness identification methods examined included photo arrays (lineups) and showups. A "showup" is a procedure that takes place shortly after a crime has occurred when the police have found a description-matched suspect. The witness or victim is driven to a location where the detained suspect is located to make an identification, usually close in proximity and time to the crime. Showups are typically conducted in the field, often from the back seat of a police vehicle where the witness or victim cannot be seen by the suspect, to allow an eyewitness to evaluate whether the detained person is the perpetrator.

Study 1: Laboratory-Based Experiment. In this experiment, participants recruited at the University of Bristol Neuroscience Festival watched actors in mock crimes. After viewing the mock suspects, they engaged in a 5-minute activity to serve as a distractor phase. Participants then returned to test their memory of the mock suspects in a showup identification procedure to measure both their confidence and the time taken to make a decision (latency).

Study 2: Field Study. This study collected data from Hartford Police Department and Denver Police Department on showup identifications conducted between 2014-2021 and 2021-2023, respectively. Data also included measures of witness confidence and latency. As the actual perpetrators were unknown in these real-world cases, the research team used a proxy for ground truth by employing a previously developed rating scale to assess evidentiary strength and to help determine the accuracy of the identifications.

Study 3: Agency Survey. Building on the Police Executive Research Forum (PERF) national survey conducted in 2011 (published in 2013), this survey assessed changes over time in U.S. law enforcement agency policies, practices, and knowledge of scientific evidence about eyewitness identification. This study focused on photographic arrays and showups, as these are the most commonly used identification methods, while avoiding questions related to mug shots, live lineups, and composite sketches.

The UCLA/Duke University National Center for Child Traumatic Stress and its partners employed mixed-methods and a community-based participatory design to investigate the impact of, response to, and recovery from four deadly school shootings and six mass violence events that occurred in the U.S. between 2012 and 2019. Key partners included the UCLA Center for Public Health and Disasters; the UCLA Department of Biostatistics; the University of California, Irvine Department of Psychological Science; the Center for Child and Family Health; and other site-specific partners. A national advisory board with 15 distinguished members informed all aspects of the project.

The goals of this study were to:

• Describe how school shootings and mass violence affect differentially exposed populations, including those injured, those who directly witnessed the violence, bereaved family members, victim service providers, first responders, local community and government leaders, and the community at large
• Examine factors at the individual, family, organization, community, and societal levels that influence severity of traumatic reactions and duration of traumatic effects to school shootings and mass violence events
• Identify secondary adversities that have affected these communities, and how such adversities have influenced recovery
• Examine perceived benefits of victim services
• Identify common themes, trends, and how media and social media influence the impact, response, and recovery of affected communities and the broader community at large

The study investigated 10 mass violence incidents: Chardon High School in Chardon, Ohio (February 27, 2012); Sandy Hook Elementary School in Newtown, Connecticut (December 14, 2012); Marysville Pilchuck High School in Marysville, Washington (October 24, 2014); Isla Vista/University of California, Santa Barbara (UCSB) (May 23, 2014); Century 16 Movie Theater in Aurora, Colorado (July 20, 2012); Washington, D.C. Navy Yard (September 16, 2013); Emmanuel AMC Church in Charleston, South Carolina (June 17, 2015); Inland Regional Center in San Bernardino, California (December 2, 2015); Pulse Nightclub in Orlando, Florida (June 12, 2016); and the Route 91 Harvest Music Festival in Las Vegas, Nevada (October 1, 2017).

Data were obtained and coded from transcripts of focus group and key informant interviews (DS1), social media using Twitter (X) (DS2 through DS8), news media articles (DS9), and secondary/external reports (e.g., after-action reports, commissioned reports, and criminal records) (DS10). The qualitative interview data (DS1) are structured as a list of coded interview quotes with their accompanying code. Users should note that analytic data files were not provided for the content analyses (DS9, DS10). Lists of sources, codebooks, and SPSS syntax files used to create the content analysis data files are available.

The overall goal of the Baby's First Years (BFY) study is to assess the causal role played by household income in affecting children's early cognitive, socio-emotional, and brain development. Recent advances in developmental neuroscience suggest that experiences early in life have profound and enduring impacts on the developing brain. Family economic resources shape the nature of many of these experiences, yet the extent to which they affect children's development is unknown. The Baby's First Years project is the first randomized controlled trial to provide estimates of the causal impacts of unconditional cash gifts on the cognitive, socio-emotional, and brain development of infants and young children in low-income U.S. families.

Specifically, 1,000 recruited mothers of infants with incomes below the federal poverty line from four diverse U.S. communities are receiving monthly cash gift payments by debit card. Mothers were initially told the gifts would last for the first 40 months of their child's life, but the study has secured funding to continue the payments for three additional years (i.e., for a total of 76 months). Parents in the high cash gift group (n=400 in the study sample) are receiving a cash gift of $333 per month ($4,000 per year), while parents in the low cash gift group (n=600) are receiving a nominal monthly gift payment of $20 ($240 per year), also for 76 months.

In order to measure the impacts of the unconditional cash gift income on children's cognitive and behavioral development, the study is assessing high and low cash gift group differences at ages 4, 6, and 8 (and, for a subset of measures, the study captures interim development at ages 1, 2, and 3) in measures of cognitive, language, memory, self-regulation, and socio-emotional development. In order to understand the processes by which child impacts emerge, the study is measuring a host of family process measures summarized in the pre-registration chart. The data collection points are referred to as: "baseline", "age 1", "age 2," "age 3", "age 4", "age 6", and "age 8".

This study was a multisite, randomized, hybrid Type 1 effectiveness-implementation (EPIS) trial designed to answer the following questions: Is a pre-treatment telehealth intervention effective in linking incarcerated women to community medication for opioid use disorder (MOUD) services upon release, and does the addition of peer navigators strengthen the intervention?

Nine-hundred women with moderate-to-high risk opioid use incarcerated in one of 9 Kentucky jails participated. Randomization was performed at the level of the jail. Data were collected every three months for up to 12 months total.

Primary effectiveness outcomes included MOUD initiation/retention, opioid overdose, relapse, and recidivism; primary implementation outcomes included optimal strategies for implementing and sustaining MOUD telehealth.

This is a documentation-only release. Data for this study are not currently available but will be added in the future.

Congenital heart defects (CHDs) are the most common type of birth defect. CHDs can be noncomplex or complex. Examples of noncomplex CHDs include an issue with one heart valve or a hole in the heart. Complex CHDs may affect several parts of the heart or the way the blood circulates. Nearly 150,000 adults in the United States have a complex CHD. Guidelines from the American Heart Association and the American College of Cardiology recommend that patients with complex CHDs see a heart doctor every one to two years. But many patients don't see a heart doctor until they have serious health problems. In this study, the research team examined how often adults with CHDs received recommended care from a heart doctor, and how outcomes differed when patients do or do not receive recommended care from a heart doctor.

A cohort of adults with noncomplex or complex CHD was recruited from across 13 sites in the United States (n=21,417) affiliated with the National Patient-Centered Clinical Research Network (PCORnet). The research team analyzed electronic health record (EHR) data and health care claims data from PCORnet that were harmonized using the Common Data Model (v6.0 and v6.1). Records data were collected retrospectively at least 1 to 3 years prior to study start (5 years maximum). Participants were also invited to join the Congenital Heart Initiative (CHI) through the Eureka Research Platform, completing online surveys about quality of life, mental health, and physical health (n=3,978).

Due to the risk of re-identification based on unique patterns in the individual-level PCORnet EHR data, patient privacy regulations prohibit the public release of the individual-level data. This collection contains the code underlying the analysis and technical specifications for the PCORnet queries.

The American National Election Studies (ANES) 2024 Time Series is a continuation of the series of election studies conducted since 1948 to support analysis of public opinion and voting behavior in U.S. presidential elections. The 2024 study features a mixed-mode design including in-person, internet, video, phone, and paper-and-pencil interviewing.

Two separate fresh cross-sectional samples were drawn, one for use with in-person interviewing as the primary mode and the second for web interviewing as the primary mode. In addition, the 2024 study features a panel of respondents previously completed the ANES in 2016 and 2020, as well as interviews with individuals who previously participated in the 2024 General Social Survey (GSS).

The goal of this study was to improve local community public health and safety outcomes for reentering justice-involved individuals who have a history of (or are at risk for) using opioids. The study compared two implementation strategies: one (vertical) in which all units in a community are trained and begin the program simultaneously and another (horizontal) in which one lead-off unit in the community is trained as a prototype of the program, the prototype is tested and refined, and then the lead-off unit helps to train other units within the community. Specific aims were to 1) increase access to and retention in community behavioral health (CBH) and medications for opioid use disorder services; 2) improve outcomes associated with public health and safety; 3) compare two implementation strategies on systems-level outcomes designed to increase service initiation and receipt of implementation and services; and 4) examine the impact of these strategies on justice-involved individuals' outcomes. The study examined both implementation and implementation-effectiveness, seeking to answer the questions of which implementation strategy is most effective for rapid and sustainable uptake of evidence-based practices and for increasing service linkage and initiation, services retention, and improved opioid-related public health safety outcomes. The study used a hybrid type 3 study design. The study's primary aim was to compare two implementation strategies and two interventions at two levels (client and system), with a secondary aim to assess client-level outcomes associated with the trial. The study design integrated 2 robust methodologies (stepped wedge and cluster randomized trial), and included 18 research performance sites (communities) located in Texas, New Mexico, and Illinois.

This is a documentation-only release, an update that includes data for this study will be added in the future.

This study assessed the implementation of an evidence-based treatment in correctional settings by comparing the effectiveness of two medications used to treat opioid use disorder: extended-release buprenorphine (XR-B) vs. extended-release naltrexone (XR-NTX) among adults who were incarcerated in U.S. jails and prisons at five distinct trial sites.

Note: This is a documentation-only release. The data will be provided in a forthcoming update to this study.

This study is part of the Seek, Test, Treat and Retain (STTR) Collaboration Project that involved over twenty studies in the fields of HIV and drug abuse. All studies were independently developed, but were chosen for the collaboration because they focused on one or more steps of the HIV treatment cascade: Seek, Test, Treat and Retain. As part of STTR Collaboration Project, the studies were grouped into Criminal Justice-related studies and Vulnerable Population-related studies. The data collected by these studies included twelve common domains (e.g., Demographic characteristics, Mental Health) in each of which a shared questionnaire or instrument was taken up by the studies and adapted to fit the study.

The data in this study focus on adult respondents' drug use, HIV-related experiences, sexual behavior, emotional and mental health, medication use, and other health-related and behavioral characteristics in South Africa from 2012 to 2014.

Almost eight million women have experienced physical violence, sexual violence or stalking by an intimate partner in the U.S. during the last 12 months. The physical and mental health consequences of intimate partner violence (IPV) on both IPV victims and their children are substantial and wide-ranging. Despite the highly prevalent, endemic levels of IPV, and the exponential growth in IPV research over the past 25 years; few effective secondary prevention strategies have been identified. One of the most effective secondary prevention efforts identified to date is the civil domestic violence protective order (DVPO). As many as 20% of IPV victims are estimated to file for a DVPO. The largest and most rigorously conducted studies to date have found full DVPOs to be strongly protective of IPV recidivism. In recent years, however, both within and outside of Washington state, IPV professionals have reported, and appellate decisions have offered confirmation, that important and potentially unsafe changes in the adjudication of these civil orders has occurred.

At the crux of many of these cases is the real concern, supported by the outcomes of appellate decisions, that victim protection is being placed secondary to concerns over DVPO respondent objections of violations of their constitutional due process or liberty rights. An additional concern is the DVPO trial court's erroneous and overly restrictive interpretations of the domestic violence protection laws. Preliminary analyses conducted by researchers with King County, Washington data, offer some indication that these changes are being reflected in changes in the outcomes of DVPO filings. Over the past twenty years, these analyses show a decreasing trend in the issuance of full DVPOs and an increasing trend in the issuance of multiple temporary orders.

The Root Causes of Bias-based Harassment in Schools study examined the prevalence and consequences of bias-based harassment among adolescents across the United States. Using a nationally representative sample of 639 adolescents aged 14-17 and their parents/guardians (at baseline) recruited through the NORC AmeriSpeak Panel, this longitudinal study collected data across four waves from October 2021 to August 2023.

The research focuses on two primary objectives: identifying rates and psychological and school-related outcomes of bias-based harassment (both victimization and perpetration) related to gender identity, religion, immigration status, sexual orientation, and race/ethnicity and determining risk and protective factors at multiple levels of the social ecology that predict bias-based harassment and influence outcomes. The surveys included in this study assessed various domains, including direct and witnessed forms of bias-based harassment, perpetration behaviors, psychological and school functioning, attitudes toward marginalized groups, peer norms, and social support.

The overall goal of this project was to conduct an evaluability assessment to help optimize implementation of prevention and reintegration efforts that incorporate psychological interventions for United States-based individuals engaged in criminal violent extremism. The specific research aims were:

1. Identify and achieve consensus on the most appropriate types of psychological-behavioral interventions for individuals engaged in criminal violent extremism or with criminal violent extremist groups that, on their own will, have requested access to such interventions.
2. Standardize the delivery and monitoring of the psychological-behavioral interventions--to the extent possible--using trainings and data collection instruments.
3. Conduct an evaluability assessment focused on the identified psychological-behavioral interventions.

For Aim 1, the research team conducted a literature review to understand what type of psychological interventions are applied in reintegration programs around the world, reviewing 67 articles that described 32 programs. To complement this review, the team also conducted interviews with practitioners with direct in-depth experience delivering psychological interventions (25 interviewed, 18 transcripts analyzed).

For Aim 2, based on findings from previous research and Aim 1, the team engaged mental health providers with experience in treating individuals with a history of engagement in criminal violent extremism to create a series of online educational videos on specifical psychological techniques and case management tools tailored to probation officers. In addition, the team conducted a Nominal Group Technique (NGT) session to clarify roles engaged in reintegration efforts and delivering psychological interventions. The NGT was conducted with 12 experts in violent extremism.

For Aim 3, the team focused on the use of dialectical behavioral therapy (DBT) for criminal extremists on probation. A purposive sample of probation officers was recruited to watch the training videos developed in Aim 2 and complete a survey on the usefulness of the videos (33 recruited, 26 completed surveys). Three officers responded to follow-up questions three months after the initial survey. Five clients with a history of engagement in violent extremism that received psychological interventions also completed surveys.

This collection currently contains only the online survey data (Aim 3). The qualitative data collected from practitioner interviews (Aim 1) and the NGT session (Aim 2) will be released in a future update. Please see the ICPSR README for more information.

This multi-site clinical research study collaborated with five county jails in Illinois and medication-assisted treatment (MAT) providers to test an adapted version of an evidence-based intervention, the Recovery Management Checkups (RMC) model, which provides quarterly check-ups and assistance with treatment retention and re-linkage as indicated at the quarterly check-ups. The study aimed to determine if tailoring the check-ups to an individuals need for treatment leads to more efficient targeting of resources to those in need, reduces the intervention burden on those with lower need, and results in an improved overall effectiveness and cost-effectiveness of RMC. Data for this study are not currently available but are forthcoming.

RTI International (RTI) and the National Police Foundation (NPF) partnered to better understand how police agencies can increase their recruitment of women into law enforcement roles. The study team identified limited resources and non-specific guidance for recruiting women officers as key factors limiting agencies' ability to recruit women, and aimed to provide more detailed guidance for agencies based on observational data and randomized controlled trials of recruitment content.

Researchers compiled Thematic Analysis Data based on the public-facing websites and social media accounts of select police agencies. Focus groups were conducted with current officers to understand their experiences and recommendations for increasing women's interest in the field, but were not included in the current data release. Lab experiments were conducted to assess the general public's reaction to short-form video and Facebook-style recruitment advertisements with varying messaging strategies, resulting in the Recruitment Experiment 1 and 2 Data. The study team also conducted field studies which developed and measured public perceptions to Google Search and Facebook advertisements for the Greensboro Police Department (GPD) and Dallas Police Department (DPD). The resulting data were compiled into the Field Study (Greensboro) and (Dallas) Data.

This study examined a pressing racial equity problem in early childhood education: the disproportionate suspension and expulsion of Black and Brown children and children with disabilities from early learning opportunities. The study centered on the legislative process conducted in Oregon during 2021 and 2022 when grassroot led bills to eliminate the use of exclusionary practices in preschool setting were introduced to the Oregon legislature.

This data collection contains anonymized qualitative data for each of the three bills involved in the process: Senate Bill 236 (2021), House Bill 2166 (2021), and House Bill 5202 (2022).

In the original study, discourse analysis was used to investigate support and opposition to structural remedies to a systemic racial equity problem.

This study is part of the American National Election Studies (ANES), a time series collection of national surveys fielded since 1948. The American National Election Studies are designed to present data on Americans' social backgrounds, political predispositions, social and political values, perceptions and evaluations of groups and candidates, opinions on questions of public policy, and participation in political life.

This file contains the original, verbatim open-ended responses to survey questions on respondents' occupation and industry. The data cover ANES Time Series studies conducted between 1996 and 2024.

The Michigan Metro Area Communities Study (MIMACS) is a panel survey of select Michigan communities residents aged 18 and older. Flint is one of the communities included in MIMACS. The initial survey in Flint was conducted in 2022 and the sample was drawn from an address-based probability sample of all occupied Flint households. The 3rd survey wave, collected between January 15 - March 18, 2024, researchers invited 823 previously enrolled panelists and 1,554 invitations to a randomly selected address-based refreshment sample of Flint households to participate in a self-administered online or interviewer-administered telephone survey. Survey topics included: Household Composition, Residence and Housing Status; Health, Social Determinants of Health, Long COVID, Mental Health; Disability; Perceptions of Neighborhood; Transportation Mode; Financial Precarity; Perception of Control; Voting; Employment; Demographics.

Tsogolo la Thanzi (TLT) is a longitudinal study in Balaka, Malwai designed to examine how young people navigate reproduction in an AIDS epidemic. Tsogolo la Thanzi means "Healthy Futures" in Chichewa, which is Malawi's most widely spoken language.

The 2019 Household Listing Data are the result of a new census of the original catchment area, 10 years after the initial study began. These data are supplemental to the main TLT series, providing insights into how the Balaka area developed over the past 10 years. It includes data from all persons living within 7 kilometers of the TLT research center.

Guided by dynamic and ecological conceptualizations of long-term resilience, this study examined whether psychosocial services delivered within juvenile residential facilities (RFs) were successful in promoting positive youth trajectories following release, whether facility violence, and, alternatively, staff connectedness influenced the effectiveness of services, and whether effects were further qualified by youth trauma history. Data for the project were drawn from the Pathways to Desistance study, which followed a large sample of juvenile offenders over seven years. A subset of 667 participants who completed release interviews following an RF stay and completed follow-up interviews were included in this study.

This collection includes the syntax files used to clean and analyze the Pathways to Desistance study Subject Measures and Release Measures data. More information about these collections and how to access these data is available on their study pages.

In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of over 7,000 Americans aged 25 to 74 (ICPSR 2760). The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health.

With support from the National Institute on Aging, an initial follow-up of the original Midlife Development in the United States (MIDUS) samples was conducted in 2004 (MIDUS 2). The daily stress and cognitive functioning projects were repeated at MIDUS 2; in addition the protocol was expanded to include biomarkers and neuroscience. In 2005, a baseline sample of 592 African Americans from Milwaukee was added to MIDUS to examine health issues in minority populations.

In 2013, a third wave (MIDUS 3) of survey data was collected on longitudinal participants. Data collection for this follow-up wave largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas (e.g., economic recession experiences, optimism and coping, stressful life events, and caregiving). A third wave of cognitive functioning data and a second wave of the Milwaukee sample were also collected. Data collection for the daily diary, biomarkers, and neuroscience is ongoing. This dataset includes mortality information for all known MIDUS decedents (N=2,822) from the Core National and Milwaukee samples as of December 2025.

The MIDUS Refresher sample is the second wave of the Midlife in the United States (MIDUS) study. The MIDUS study seeks to understand how factors in the lives of American adults such as working conditions, relationships, health, finances, personal outlooks and individual choices impact health and well-being as individuals age from early adulthood to later life. This second wave of the study with the refresher sample also sought to shed light on how U.S. adults have been impacted by the COVID-19 pandemic and how these experiences are linked with their health, broadly defined.

In 2022-2025, the second wave of cognitive assessments were carried out on the MIDUS Refresher participants who had completed the MIDUS Refresher 2 survey interview. The first part of the assessments consists of the Brief Test of Adult Cognition via Telephone (BTACT) including seven subtests: word list recall immediate, word list recall delayed, backward digit span, number series, counting backward speed, category fluency, and an attention switching reaction time task. The second part consists of the Montreal Cognitive Assessment (MoCA-BLIND), which is newly introduced at the Refresher 2. It is an adapted version of the original MoCA, a rapid screening instrument for mild cognitive dysfunction, and tests seven cognitive domains: attention and concentration, memory, language, conceptual thinking, calculations, and orientation.

This study is the largest survey of community college trustees to date. It was conducted jointly by the Association of Community College Trustees (ACCT) and the Center for the Study of Community Colleges (CSCC).

Tsogolo La Thanzi (TLT) is a decade-long population-based cohort study of young women and men from Balaka, Malawi. Tsogolo La Thanzi means "Health Futures" in Chichewa, Malawi's most widely spoken language. TLT has followed young adults (ages 15-25 at enrollment, 15-35 inclusive) as they navigate relationships and childbearing within the context of a generalized AIDS epidemic. TLT enrolled more than 3000 individuals and collected 11 waves of data, covering a 10-year period (2009-2019) that spans massive changes in the HIV treatment context in Malawi as well as the ages of peak incidence and peak fertility for female respondents.

This particular study contains the data collected from an additional survey referred to as Tsogolo La Thanzi 3 (TLT-3), fielded in 2019, following the release of ten waves of data collected between 2009 and 2015. Unlike the past where the sample included male partners, this third round of data collection focused solely on women.

TLT-3 covered many of the same topics found in the original TLT multi-wave project such as: relationships, religion, HIV/AIDS, pregnancy, marriage, sexually transmitted diseases, and future expectations.

Additionally, modules specific to TLT-3 included: kinship, mental health, and trust in clinics. These data can be used cross-sectionally or can be merged with previous waves to facilitate analyses of a full ten years of social change in Balaka township and across the life course.

The standard care of hospital or emergency department patients experiencing an acute ischemic stroke includes intravenously administered tissue plasminogen activator (tPA). Mobile stroke units (MSUs) are ambulances equipped with staff and a computed tomographic scanner that can allow for tPA to be administered more quickly. This comparative effectiveness trial examined clinical outcomes in stroke patients who received either an earlier diagnosis and treatment using an MSU or standard triage and transport by Emergency Medical Services (EMS). The sample included multicenter cohorts with randomized deployment weeks and blinded assessment of both trial entry and clinical outcomes.

Fathers Empowered to Learn, Lead, and Achieve Success (FELLAS) is a Responsible Fatherhood program, funded by the Office of Family Assistance, and provided by the Partnership for Maternal and Child Health in Northern New Jersey. The program served community-based fathers aged 18 and older who reside in Essex County, New Jersey. To be eligible for the program, fathers must have had at least one child aged 24 or younger. Expectant fathers were eligible. The FELLAS program consisted of three key components:

• Responsible Parenting: Uses 24/7 Dad, an evidence-based, father-focused parenting curriculum designed to enhance parenting skills.
• Healthy Marriage/Relationship Skills: Incorporates Couple Communication I, an evidence-based curriculum that includes home visits to strengthen relationships and marriage dynamics.
• Economic Stability: Provides a comprehensive set of services, including employment assessments, basic technology training, and pre-employment soft skills development.

The core program consisted of 35 hours of intensive workshops, broken down as follows:

• 24 hours of 24/7 Dad group sessions
• 6 hours of economic stability group sessions
• 5 hours of Couple Communication I group sessions
• The program was taught over 15 weeks, two-three hours per week

For the five weeks prior to the start of each cohort, the Father Program Specialists (FPSs) recruited fathers by conducting street outreach throughout Essex County, outreach in-person at childcare centers and schools, outreach and marketing to local partners requesting referrals to the program. They also encouraged fathers who had previously completed the program to assist with word-of-mouth marketing. Recruitment was also facilitated, in part, by The Partnership's extensive experience in the community. Two cohorts were conducted each year. Each FPS facilitated the FELLAS programming for the fathers he recruited and also served as the case manager for these fathers.

The Bureau of Justice Statistics (BJS) initiated a multiyear effort to improve the efficiency, reliability, and utility of the National Crime Victimization Survey (NCVS). The effort had three main goals: modernize the organization and content of the NCVS instrument, increase the quality of information collected and efficiency of the instrument flow, and improve the measurement and classification of crime. To that end, BJS is redesigning the entire survey instrument, which includes a household roster, a victimization screener, and a detailed crime incident report (CIR). Each of these instrument components were examined in the NCVS Instrument Redesign Field Test. This large-scale national field test was conducted from October 2019 to March 2020 to compare the performance of the current NCVS instrument and procedures (Condition 1) against the redesigned instrument (Condition 2). For more details on this effort, see the NCVS Instrument Redesign webpage.

After the large-scale field test, a smaller test was conducted that assessed the feasibility of conducting the NCVS as a self-administered, web-based instrument. This test included two samples: an address based sample (Condition 3A) and a sample of individuals who were part of an existing web-based panel (Condition 3B). For more details on this effort, see the NCVS Instrument Redesign webpage.

The Seek, Test, Treat and Retain (STTR) Collaboration Project involved over twenty studies in the fields of HIV and drug abuse. These studies were independently developed, but were chosen for the collaboration because they focused on one or more steps of the HIV treatment cascade: Seek, Test, Treat and Retain. These studies were grouped into Criminal Justice-related studies and Vulnerable Population-related studies. The data collected by these studies included twelve common domains (e.g. demographic characteristics, mental health) in each of which a shared questionnaire or instrument was taken up by the studies and adapted to fit the study. This repository contains the collected data and documentation from the STTR collaboration.

This study in particular is part of the Urban Health Studies project, specifically assessing treatment outcomes of high-risk probationers and parolees with HIV in California from 2012 to 2013.

This study contains data from the Northwestern Juvenile Project (NJP) series, a prospective longitudinal study of the mental health needs and outcomes of youth in detention.

The purpose of this study was to examine the dose of incarceration and subsequent psychiatric and psychosocial functioning in 1,829 justice-involved youths in Chicago, Illinois 16 years after detention.

The study publication, "Incarceration and Subsequent Psychosocial Outcomes: A 16-Year Longitudinal Study of Youth After Detention", was published in April 2025 in the Journal of the American Academy of Child and Adolescent Psychiatry.

Drug use remains a major public health problem among youth in the United States. Effective implementation of evidence-based interventions for youth is critical for reducing the burden of drug use and its consequences. The Michigan Model for Health (MMH) is a universal prevention curriculum that has demonstrated efficacy in reducing adolescent substance use. Fidelity is essential to intervention effectiveness, yet youth rarely receive evidence-based interventions (EBIs) as intended; this is partly due to a poor fit between the intervention and the context. The disconnect between the EBI and context is especially pronounced among underserved and vulnerable populations, including among youth exposed to trauma. Trauma is a potent risk factor for substance use, abuse, and the development of substance use disorders. Consequently, there is a critical need to design and test effective, cost-efficient implementation strategies to optimize the fidelity of school-based drug use prevention to meet better the needs of youth exposed to trauma. The study designed and tested a multi-component implementation strategy to improve intervention-context fit and enhance fidelity and effectiveness.

This study was using a 2-group, mixed method, randomized trial design, this pilot study compared standard implementation (Replicating Effective Programs [REP]) versus enhanced REP to deliver MMH. REP is an implementation strategy bundle that promotes EBI fidelity through curriculum packaging, training, and as-needed technical assistance. Enhanced REP incorporates tailoring of the EBI package and training and deploys customized implementation support (i.e., implementation facilitation). The research focuses on youth at heightened risk of drug use and its consequences due to trauma exposure.

This NIJ-funded study used a data driven approach to understand rural police department responses to the opioid crisis. Researchers compiled County-Level Drug Data on overdose deaths to understand the spatio-temporal distribution of drug misuse and to identify counties with high levels of death that are doing better and worse than expected according to an inclusive statistical model. In combination with this data, researchers collected Police Agency Survey Data from police departments in four states to understand departments' access to intelligence resources. Based on this survey, six agencies with varying law enforcement structural relations with state-level agencies were selected to participate in the study intervention. Departments were partnered with mentors and encouraged to enhance their intelligence networks, design a simple initiative, equip themselves for it, and carry it out. Outcomes from the intervention were evaluated through survey data - available as Implementation Site Administrative and Survey Data - and through a series of qualitative interviews, which will be made available at a later date.

This project examined the implementation of student threat assessment in Florida public schools. Researchers investigated threat assessment training and implementation, which types of threat cases schools experienced, and how cases were resolved. This project used a mixed-method approach with four broad research questions: (1) What are stakeholder reactions to training and implementation of threat assessment in their school? (2) What are the characteristics of threat assessments conducted in Florida public schools? (3) What relationships exist among academic, disciplinary, and legal outcomes for students receiving a threat assessment? (4) Are there adverse disparities in student outcomes associated with race, ethnicity, or special education status?

The data produced by this study include three Case Data datasets (DS1-3), comprised of Florida Department of Education (FLDOE) case data on student threats from the 2020-21 and 2021-22 school years; two Training Survey Data datasets (DS4/5), containing results from surveys of participants who completed Comprehensive School Threat Assessment Guidelines (CSTAG) trainings; and Needs Assessment Survey Data (DS6) from a survey of district school safety leads assessing needs and concerns about their district's threat assessment process.
