In October 2013, the Pacific Institute for Research and Evaluation (PIRE), in partnership with Big Brothers Big Sisters of Kentuckiana (BBBS-KY), was funded by the Office of Juvenile Justice and Delinquency Prevention (OJJDP) to implement a mentoring research best practices project that explored whether three types of parent/guardian level variables (psychosocial parent/family characteristics, parent engagement in the mentoring match, and parenting style) influence match quality, match length, and youth outcomes.

This study was designed to describe these factors, as well as investigate how these factors impact match length, match strength, and youth program outcomes. Data to inform both objectives was collected using a longitudinal multimode approach with youth, mentors and parents in the BBBS-KY program in the metro Louisville area. In addition, data from 16 local school districts provided measures of academic performance, school attendance, and disciplinary suspensions. Data were collected at multiple time points from youth, volunteer mentors, and parents/guardians. These data included BBBS-America standard surveys (Youth Outcomes Survey, and Volunteer and Youth Strength of Relationship Surveys). PIRE supplemented the standard BBBS data collection efforts with project-specific baseline volunteer mentor survey and several formative and outcome based inserts to supplement the data that was regularly collected from youth and mentors. The PIRE and BBBS-KY teams also created a project-specific parent/guardian survey to better understand the impact of parental factors on match dynamics and youth mentoring program outcomes. Due to low literacy levels of parents/guardians, this survey was administered as a mixed-mode, audio-computer assisted interview (ACASI). Additional data sources for this study included data from (a) coding of qualitative case review notes for selected aspects of matches by BBBS-KY match support specialists, (b) academic data collected from school districts, and (c) data collected on general match characteristics (e.g., match closure status) collected by BBBS-KY as part of their standard business operations. Most measures were collected early in the match (either match formation or three months into the match) and at 12 months into the match.

Dating It Safe is a longitudinal cohort study of 1,042 youth in southeast Texas. Primarily freshmen high school students were recruited and assessed in the spring of 2010. Follow-up waves were collected annually each spring from 2011 through 2017 (Waves 2-8). The primary aims of this research study were to examine the:

• longitudinal association between the three different forms of teen dating violence (TDV; i.e., physical violence, psychological abuse, and sexual aggression), and
• risk and protective factors of TDV perpetration and victimization.

Guided by a life course perspective, this study used a mixed methodological approach (i.e., quantitative administrative data and qualitative interviews) to identify the differences in events, motivations, and experiences related to gang affiliation and the differences across (a) system-documented, gang-involved individuals, (b) system-documented gang-involved individuals who have gang-involved family members, and (c) other high-risk youth who are suspected of involvement. The overall goal of this research was to identify distinct pathways to gang activity that could inform practitioners and policymakers about useful intervention strategies. The study context was specific to Multnomah County, Oregon.

To achieve this, separate and distinct juvenile and adult systems databases were integrated to create critical linkages between juvenile services data (including risk assessments), adult community corrections data, and federal corrections data (n=2,210 individual records). This allowed for the examination of the trajectory of each individual - regardless of gang system documented gang status - from juvenile services through state adult corrections through federal adult corrections. It also permitted the investigation into the similarities or differences among different system-identified groups (i.e., gang involved, suspected gang involved, or no documentation of gang involvement). Additionally, the inclusion of familial and peer criminal justice records and system gang identification enabled the research team to control for family and peer influences while focusing on how the father's criminality and gang status might be a risk factor for youth criminal legal involvement and escalation into the adult system. Research questions for the quantitative data collection were:

1. What aspects of early criminal offending and other problematic behaviors differ between gang-affiliated youth, gang-affiliated youth with gang-involved parents, and other high-risk youth?
2. Are there significant differences in the likelihood of youth escalation into the adult criminal justice system and the Federal Corrections System between gang-affiliated youth, gang-affiliated youth with gang-involved parents, and other high-risk youth?
3. Are there consistent age-related trends in risk as measured by the Juvenile Crime Prevention (JCP) tool? Do these trends vary by gang-affiliated youth, gang-affiliated youth with gang-involved parents, and other high-risk youth?
4. What is the timing of important life events across the life course of justice-involved youth? Does the timing differ between gang-affiliated youth, gang-affiliated youth with gang-involved parents, and other high-risk youth?
5. Does the close proximity of the timing of these life events increase the likelihood of youth escalation into the adult criminal justice system and the Federal Corrections System? Do these predictions differ between gang-affiliated youth, gang-affiliated youth with gang-involved parents, and other high-risk youth?
6. How do parental offending and incarceration patterns predict their child's likelihood of becoming gang-affiliated and likelihood of escalation into the adult criminal justice system?
7. How do the answers to the above research questions vary by youth race, ethnicity, geography, and offense type?

In addition to quantitative measures of gang pathways, semi-structured interviews were conducted with two groups: gang-affiliated and gang-involved youth supervised in the Department of Community Justice Gang Unit during the study time period (n=32), and corrections staff who had current or previous experience working with gang-affiliated or gang-involved youth (n=12). Original research questions for the qualitative data collection were:

1. What are the critical transition periods for becoming gang-affiliated, and how are they experienced as an emotional event and/or a deliberate decision? How do these differ between individuals who have no criminal justice system involved family members, individuals with criminal justice involved family members, and individuals with gang-affiliated family members?
2. What is the relational and emotional experience of recruiting a familial relation to gang affiliation, and of being recruited by a familial relation to gang affiliation and gang activities?
3. What are the motivations for recruiting a familial relation into gang affiliation, and for allowing oneself to be successfully recruited by a family member?
4. What are the methods employed by gang-affiliated individuals in recruiting their family members?
5. Do the recruiter and recruited have significant or patterned differences in the event and experience of recruitment into gang affiliation and activities?
6. Do the recruiter and recruited have significant or patterned differences in their views and experiences of the criminal justice system?

Qualitative data will be made available in a future update.

Teenage adolescent females residing in Baltimore, Maryland who were involved in a relationship with a history of violence were sought after to participate in this research study. Respondents were interviewed and then followed through daily diary entries for several months. The aim of the research was to understand the context regarding teen dating violence (TDV). Prior research on relationship context has not focused on minority populations; therefore, the focus of this project was urban, predominantly African American females.

The available data in this collection includes three SAS (.sas7bdat) files and a single SAS formats file that contains variable and value label information for all three data files. The three data files are:

• final_baseline.sas7bdat (157 cases / 252 variables)
• final_partnergrid.sas7bdat (156 cases / 76 variables)
• hart_final_sas7bdata (7004 cases / 23 variables)

This project studied the capacity of family group conferencing (FGC) to enhance public safety by equipping returning citizens with the skills and insight to repair relationships and reintegrate successfully into their communities and families. FGC is guided by the philosophy of restorative justice, meaning that crime primarily causes harm to people and relationships and, in turn, creates an obligation to repair that harm. FGC brings together the people most affected by a crime to discuss what happened, learn how people have been affected, and decide what needs to be done to repair the harm.

The project evaluated an FGC program implemented by Supporting Restorative Reentry in Detroit at a residential reentry center in Detroit, Michigan. Researchers used a randomized control trial with high-risk, formerly incarcerated participants still under Michigan Department of Corrections supervision with the goal of assessing the programs ability to reduce recidivism and increase quality of life for returning citizens, their families, and their communities. Variables include measures of criminal identity, optimism, personal agency, social bonds, the FGC process, risk scores, and twelve-month recidivism follow-up. Participants' age, gender, and race demographics are also collected.

This project utilized three strategies to investigate the impact of incarceration on families. First, a statewide integrated data system was used to examine impacts of incarceration in a novel way, using administrative data from corrections, juvenile justice, mental health, social services, substance use services, healthcare, and education. Second, researchers linked multi-agency data to address specific research questions regarding impact of incarceration on families, including impact of incarceration on family physical and mental health, children's involvement with the child welfare and juvenile justice systems, family economic status, and school performance. Third, researchers conducted focus groups and family interviews with 77 inmates and 21 inmate family members sampled from three correctional facilities. Researchers identified qualitative themes regarding impact of incarceration in the lives of inmates and their families.

Only data from the focus groups is included in this collection. The collection includes two SPSS data files: "Inmate_Demographic_Data.sav" with 15 variables and 77 cases and "Family_Demographic_Data.sav" with 19 variables and 21 cases. The actual focus group interviews with inmates and their family members are not available as part of this collection at this time. Administrative data from the South Carolina Revenue and Fiscal Affairs Office was not made available for archiving. Users interested in obtaining these data should consult the accompanying documentation.

These surveys of 12th-grade students are part of a series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students are randomly assigned to complete one of six questionnaires, each with a different subset of topical questions, but all containing a set of "core" questions on demographics and drug use. There are about 1,400 variables across the questionnaires. Drugs covered by this survey include tobacco, smokeless tobacco, alcohol, marijuana, hashish, prescription medications, over-the-counter medications, LSD, hallucinogens, amphetamines (stimulants), Ritalin (methylphenidate), sedatives/barbiturates, tranquilizers, cocaine, crack cocaine, GHB (gamma hydroxybutyrate), ecstasy, methamphetamine, and heroin. Other topics include attitudes toward religion, changing roles for women, educational aspirations, self-esteem, exposure to drug education, and violence and crime (both in and out of school).

Highlights for 2019:

• Change in methodology: half of the MTF schools completed in-class surveys on tablets loaded with the survey; the other half completed traditional paper-and-pencil surveys. Also see the Methodology section on this page for an overview and the codebook for details.
• Expansion and revision of the study documentation in the codebook
• New documentation available for download detailing the question adds/drops/changes to the surveys
• Availability of supplemental data sets for previously unreleased questions

Two supplemental data files (DS8 and DS9) have been included this year by the Principal Investigators. These files each include three administrative variables for year (V1), form (V3), and ID (RESPONDENT_ID) along with a few additional variables of survey questions not previously released for Form 5 (DS8) and Form 6 (DS9) between the years 2016 to 2018. These same variables are already present in the main 2019 data files for Form 5 (DS6) and Form 6 (DS7). The front section of the codebook provides details about each of the variables. There are also instructions on how to merge the supplemental data on to the main data files for the previous three years:

• 2018 data (ICPSR 37416)
• 2017 data (ICPSR 37182)
• 2016 data (ICPSR 36798)

Highlights for 2020:

• All students recorded their survey answers on tablets that the project brought to the schools, preloaded with the MTF surveys.
• Data collection was halted prematurely on March 15, 2020 when the University of Michigan stopped all projects that involved face-to-face data collection because of COVID-19 concerns. This resulted in a 2020 sample size about 25% the size of a regular data collection.
• Guidance for combining grades for analysis: see Appendix C of the codebook.
• Information about potential mode effects for questions on student attitudes and beliefs when comparing previous years' paper-based survey responses to the current tablet method of collection. Please see the codebook Introduction - Survey Mode section for details.

The Supplemental Fraud Survey (SFS) obtained additional information about fraud-related victimizations so that policymakers; academic researchers; practitioners at the federal, state, and local levels; and special interest groups who are concerned with these crimes can make informed decisions concerning policies and programs. The SFS asked questions related to victims' experiences with fraud. These responses are linked to the National Crime Victimization Survey (NCVS) survey instrument responses for a more complete understanding of the individual victim's circumstances.

The 2017 Supplemental Fraud Survey (SFS) was the first implementation of this supplement to the annual NCVS to obtain specific information about fraud-related victimization and disorder on a national level. Since the SFS is a supplement to the NCVS, it is conducted under the authority of Title 34, United States Code, section 10132. Only Census employees sworn to preserve confidentiality may see the completed questionnaires.

The National Survey of Teen Relationships and Intimate Violence (STRiV) examines the changing nature of adolescent dating relationships, particularly those marked by adolescent relationship abuse (ARA). More specifically, this study was designed to produce nationally representative estimates of the prevalence of multiple forms of ARA among youth (ages 10-18), to document the characteristics of abusive relationships during adolescence, to assess ARA risk factors, and to situate these estimates within the environment of adolescents' key social relationships and communications.

STRiV includes individual data from a nationally representative sample of households with at least one resident youth. Baseline and follow-up surveys were completed using a secure web survey with toll-free telephone and online help available.

The Pittsburgh Youth Study (PYS) is part of the larger "Program of Research on the Causes and Correlates of Delinquency" initiated by the Office of Juvenile Justice and Delinquency Prevention in 1986. PYS aims to document the development of antisocial and delinquent behavior from childhood to early adulthood, the risk factors that impinge on that development, and help seeking and service provision of boys' behavior problems. The study also focuses on boys' development of alcohol and drug use, and internalizing problems.

PYS consists of three samples of boys who were in the first, fourth, and seventh grades in Pittsburgh, Pennsylvania public schools during the 1987-1988 academic year (called the youngest, middle, and oldest sample, respectively). Using a screening risk score that measured each boy's antisocial behavior, boys identified at the top 30 percent within each grade sample on the screening risk measure (n=~250), as well as an equal number of boys randomly selected from the remainder (n=~250), were selected for follow-up. Consequently, the final sample for the study consisted of 1,517 total students selected for follow-up. 506 of these students were in the oldest sample, 508 were in the middle sample, and 503 were in the youngest sample.

Assessments were conducted semiannually and then annually using multiple informants (i.e., boys, parents, teachers) between 1987 and 2010. The youngest sample was assessed from ages 6-19 and again at ages 25 and 28. The middle sample was assessed from ages 9-13 and again at age 23. The oldest sample was assessed from ages 13-25, with an additional assessment at age 35. Information has been collected on a broad range of risk and protective factors across multiple domains (e.g., individual, family, peer, school, neighborhood). Measures of conduct problems, substance use/abuse, criminal behavior, mental health problems have been collected.

This collection contains data and syntax files for family interaction constructs. The datasets include constructs on: relationships and communication with parents/caretakers; parental monitoring and caretaker supervision; counter-control by the child; family involvement, including getting along with siblings; persistence of discipline; physical punishment; caretaker anti-social attitudes; positive parenting; and quality time.

The family constructs were created by using the PYS raw data. The raw data are available at ICPSR in the following studies: Pittsburgh Youth Study Youngest Sample (1987 - 2001) [Pittsburgh, Pennsylvania], Pittsburgh Youth Study Middle Sample (1987 - 1991) [Pittsburgh, Pennsylvania] , and Pittsburgh Youth Study Oldest Sample (1987 - 2000) [Pittsburgh, Pennsylvania].

The Toledo Adolescent Relationships Study (TARS) explores the relationship qualities and the subjective meanings that motivate adolescent behavior. More specifically, this study seeks to examine the nature and meaning of adolescent relationship experiences (e.g. with family, peers, and dating partners) in an effort to discover how experiences associated with age, gender, race, and ethnicity influence the meaning of dating relationships. The study further investigates the relative impact of dating partners and peers on sexual behavior and contraceptive practices, as well as involvement in other problem behaviors that can contribute independently to sexual risk-taking. The longitudinal design of the Toledo Adolescent Relationships Study (TARS) includes a schedule of follow-up interviews occurring one, three, five, ten, and about eighteen years after the initial interview. Additional waves have since been conducted.

Wave 1 of TARS includes detailed data collected from both parents and adolescent respondents about their relationship experiences, including self-reported data from parents, parent-reported data about adolescent respondents, and self-reported data from adolescent respondents. These data are available as a combined dataset organized by adolescent respondent.

The Toledo Adolescent Relationships Study (TARS) includes several waves of data collection available through ICPSR. Please see the ICPSR Series page for available studies.

The longitudinal design of the Toledo Adolescent Relationships Study (TARS) includes a schedule of follow-up interviews occurring one, three, and five years after the initial interview. Four prior waves of data have been collected (2001, 2002, 2004, and 2006). Data were collected from adolescent respondents through structured in-home interviews utilizing laptop computers.

In addition, the fifth wave, conducted in 2011 when the participants were young adults, builds on prior waves by adding quantitative and qualitative assessments of intimate partner violence (IPV).

This study builds on a 20-year longitudinal investigation of the lives and relationship experiences of a large, diverse sample of young adult women and men interviewed first as adolescents. It focuses on the phenomenon of social distancing.

The COVID-19 survey (online) module and in-depth (phone) interviews with subsamples of compliant and less than compliant respondents has three specific aims: a) identify life course experiences and social influences associated with variability in compliance with social distancing recommendations, b) examine relationship-based dynamics and other contingencies (e.g., economic) linked to compliance decision-making, and particularly factors associated with 'derailments' after initially intending to comply with these guidelines, and c) assess consequences of social distancing for emotional and behavioral health and relationship functioning (e.g., depression, substance use, intimate partner conflict).

The Toledo Adolescent Relationships Study (TARS) includes six prior waves of data that were collected in 2001, 2002, 2004, 2006, 2011, and 2018 through 2020. Please see the ICPSR Series page for available studies.

Somalis in North America offer a window into the remarkable potential that can be realized by refugees/immigrants despite experiences of severe adversity as well as the challenges some subgroups encounter when adjusting to life in a new country. Somalia has endured one of the longest and most brutal wars of the past 30 years. This enduring conflict has led to millions of Somalis being dispersed as refugees across the globe. As refugees with limited resources, many Somalis in North America are resettled in poor urban neighborhoods where they are visibly different, not only because of race or ethnicity but also because of dress, especially for women who wear a Muslim head covering.

In addition, the community has been plagued by violence. While the number of Somali American youth joining these groups are small and while the majority of Somali Americans are law-abiding citizens, the terrorist groups' ability to recruit these youth and to convince some of them to engage in violent acts is concerning, not only to policymakers and law enforcement, but also to the Somali community, which fears losing more youth to violence or having the community's reputation sullied by being associated with terrorism.

While some of the social and cultural factors affecting Somalis are unique to that ethnic group, they also share experiences common to many immigrants, navigating identity development and duality as they move between home and host cultures, contending with discrimination as religious, racial and ethnic minorities, and striving to achieve their dreams while struggling to gain socioeconomic stability. Thus, understanding their developmental trajectories may inform the understanding of other immigrant and refugee groups as well.

No valid and reliable measurement for risk for violent extremism exists; there is no single profile or set of risk factors that can accurately determine who is most at risk for engaging in violent extremist acts. The study did not attempt to determine who is most at risk. Rather, the researchers sought to identify broad attitudes that would indicate a general openness to, or rejection of, the use of violence or illegal actions in support of a political cause.

The qualitative interviews feature experiences of formal (e.g. police) and informal (e.g. community) institutions over the past year. Examples of interview prompts include questions related to social bonds with family and community, and interactions with police.

This secondary data analysis study combined social disorganization and self-control theories to understand violent victimization among children and adolescents. The study used data from 1,889 youth from the 9, 12, and 15-year-old cohorts of the Longitudinal Cohort Study in the Project on Human Development in Chicago Neighborhoods (PHDCN). The PHDCN was an interdisciplinary study on how the contexts in which children and adolescents reside contribute to their behavior and psychological development.

Data analyzed for this study were from self-reports of children, adolescents, and their primary caregivers during waves 1 and 2 of the longitudinal data collection effort. In addition, neighborhood structural characteristics from the U.S. Census were also analyzed.
