A Comparative Study of Violent Extremism and Gangs, United States, 1948-2018 (ICPSR 37386)
The study assesses the extent of commonalities between individuals who become involved in violent extremist groups and criminal gangs, and the processes by which individuals engage in each group. Following this comparison, the extent to which the empirical results support the potential for anti-gang programs to bolster the resilience of communities against violent extremism and other forms of crime is assessed.
Quantitative assessment was conducted by comparing individuals included in the Profiles of Individual Radicalization in the United States (PIRUS) dataset with a subset of individuals drawn from the National Longitudinal Survey of Youth 1997 (NLSY97) along a number of demographic, social, and socioeconomic characteristics.
Supplementary survey data was also collected from 45 former and current gang members in the United States concurrently with long-form interviews, covering a range of variables including background characteristics, demographic information, and attitudes among the respondents.

Gang Affiliation and Radicalization to Violent Extremism within Somali-American Communities, 5 North American Cities, 2013-2019 (ICPSR 37466)
How is the process of radicalization understood over time? Do current radicalization to violence differ from earlier waves? How can these understandings be utilized to prevent radicalization to violence and--equally important--understand the reach and impact of programs designed to do so? The overall goal of this project was to pursue the following aims:
- Aim 1: To understand how adversity and social bonds relate to changes in openness to violent extremism over time.
- Aim 2: To evaluate experience and perception of, and the effectiveness of, Countering Violent Extremism (CVE) activities.
- Aim 3: To evaluate mechanisms of change in violent extremism.
- Aim 4: To understand similarities/ differences in experiences and/or histories of Somali youth who joined Al-Shabab vs. those known to have been killed in Syria, fighting with ISIS and other terrorist groups.
The above aims were accomplished through extending an ongoing longitudinal research program to span 5 years, and expanding a psychological autopsy sample to include Somali youth who have left Minneapolis and been killed fighting with ISIS and other terrorist groups in Syria. Data collection for the longitudinal study consisted of conducting an additional wave of structured interviews with Somali youth (between the ages of 21-33); interviews included assessments of structural adversity (resettlement hardships, trauma exposure, and discrimination), social factors (connection to the resettlement community and/or Somali diaspora community, internet use, and level of acculturation) delinquency, gang involvement, civic engagement, and support for legal and illegal (violent) actions in support of political change. The researchers used latent transition analysis (LTA), generalized estimating equation modeling, and linear regression modeling to accomplish Aims 1-3. Aim 4 was accomplished by using a combination of open source data analysis, psychological autopsy and case analysis methodology. The researchers expanded our current in-depth case studies of Somali youth who left Minneapolis to join al-Shabaab (N = 23, males aged 22-30) to include those who joined ISIS or Al-Nusra (N=4, males aged 18-29). Research questions associated with Aim 4 were analyzed using a psychological autopsy method of developing case histories. Case histories were coded for themes and analyzed for convergence or divergence with case histories of youth who joined Al-Shabab. Scholarly products include manuscripts in journals relevant to criminal justice, policy briefs, and interim and final reports. This project builds on partnerships between Boston Children's Hospital, Somali communities, and Georgia State University.
Intra- and Intergenerational Aspects of Serious Domestic Violence and Alcohol and Drug Abuse in Buffalo, 1987 (ICPSR 9984)
Multi-State Recidivism Study Using Static-99R and Static-2002 Risk Scores and Tier Guidelines From the Adam Walsh Act, Florida, Minnesota, New Jersey, South Carolina, 1990-2004 (ICPSR 34628)
This study seeks to examine important components of our nation's sex offender tracking and monitoring systems, with a focus on risk assessment and sexual recidivism (measured by re-arrest). Data were collected from 1,789 adult sex offenders in the following states.
- Florida: 500 cases
- Minnesota: 500 cases
- New Jersey: 291 cases
- South Carolina: 498 cases
The data file contains another 551 cases from the state of Massachusetts. However, due to how and when those cases were identified they were not included in the Principal Investigator's focus and analysis. There are also another 151 cases where a study participant's state is missing. Total there are 2,491 cases and 1,947 variables.
Offender Decision-Making: Decision Trees and Displacement, Texas, 2014-2017 (ICPSR 37116)
These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.
This research expanded on offenders' decisions whether or not to offend by having explored a range of alternatives within the "not offending" category, using a framework derived from the concept of crime displacement. Decision trees were employed to analyze the multi-staged decision-making processes of criminals who are blocked from offending due to a situational crime control or prevention measure. The researchers were interested in determining how offenders evaluated displacement options as available alternatives. The data were collected through face-to-face interviews with 200 adult offenders, either in jail or on probation under the authority of the Texas Department of Criminal Justice, from 14 counties. Qualitative data collected as part of this study's methodology are not included as part of the data collection at this time.
Three datasets are included as part of this collection:
- NIJ-2013-3454__Part1_Participants.sav (200 cases, 9 variables)
- NIJ-2013-3454__Part2_MeasuresSurvey.sav (2415 cases, 6 variables)
- NIJ-2013-3454__Part3_Vignettes.sav (1248 cases, 10 variables)
Demographic variables included: age, gender, race, and ethnicity.
