Adjusting the National Crime Victimization Survey's Estimates of Rape and Domestic Violence for Gag Factors, 1986-1990 (ICPSR 6558)

Released/updated on: 1996-10-01
Geographic coverage: United States
Time period: 1986-01-01--1990-01-01
The purpose of this project was to use statistical modeling techniques to estimate rape and domestic assault rates, adjusting for interviewing conditions under which the National Crime Victimization Survey (NCVS) was administered. Data for women 16 years of age and older interviewed in the NCVS (see NATIONAL CRIME SURVEYS: NATIONAL SAMPLE, 1986-1990 [NEAR-TERM DATA] [ICPSR 8864]) were analyzed. The researchers considered whether the type of interview (personal or telephone) and the presence of another person (particularly a spouse) influenced or "gagged" the reporting of rape and domestic violence in the NCVS. The researchers also investigated correlates, primarily demographic in nature, of reporting rape, domestic violence, other assaults, and breaking and entry. In total, the data file contains reports of 434 rapes, 1,973 incidents of domestic violence, 13,459 other assaults, and 88,950 incidents of breaking and entry. The binary-coded variables provide information on whether the respondent was alone during the interview, others who were present, whether the interview was by telephone, whether the respondent refused a telephone interview, the number of persons who lived in the household, whether the respondent owned her home, whether the land use was urban, whether the household the respondent was living in was the same household from the last interview, whether the respondent had moved more than three times in the last five years, and whether an assault, domestic violence incident, rape, breaking and entry, or no crime was reported. Demographic information includes the respondent's education, income, employment during the last six months, marital status at the time of the interview, and whether the respondent was white (or non-white) or Hispanic (or non-Hispanic). Variables coded the same as the NCVS variables include age, respondent's relationship to the offender, type of crime, year and quarter of interview, NCVS control number, and person weight.

Alternative Probation Strategies in Baltimore, Maryland (ICPSR 8355)

Released/updated on: 2006-01-12
Geographic coverage: Baltimore, United States, Maryland
The purpose of this study was to assess the relative cost-effectiveness of supervised probation, unsupervised probation, and community service. Data were collected from several sources: input-intake forms used by the State of Maryland, probation officers' case record files, Maryland state police rap sheets, FBI sources, and interviews with Maryland probationers. Non-violent, less serious offenders who normally received probation sentences of 12 months or less were offered randomly selected assignments to one of three treatment methods over a five-month period. Baseline data for probationers in each of the three samples were drawn from an intake form that was routinely completed for cases. An interim assessment of recidivism was made at the midpoint of the intervention for each probationer using information drawn from police records. Probationers were interviewed six and twelve months after probation ended. Demographic information on the probationers includes sex, race, age, birthplace, marital status, employment status, and education.

Analysis of Rhode Island Domestic Violence Offenders on Probation, 1977-2012 (ICPSR 34571)

Released/updated on: 2016-05-20
Geographic coverage: Rhode Island, United States
Time period: 1977-02-01--2012-07-01

These data are part of NACJD's Fast Track Release and are distributed as they there received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except of the removal of direct identifiers. Users should refer to the accompany readme file for a brief description of the files available with this collections and consult the investigator(s) if further information is needed.

The purpose of the study was to:

  • Describe the prosecution and sentencing histories for domestic violence and other offenses;
  • Determine the severity gap in prosecution and sentencing between these domestic violence and non-domestic violence over a six year period; and
  • To answer whether the variation in prosecution and sentencing severity predicts being subsequently charged for domestic violence in the future.

Rhode Island was selected as the study site because it has a high domestic violence arrest rate and specifically distinguishes domestic violence from non-domestic violence offenses based on the relationships of the parties, not by specific type of crime. Further, Rhode Island's judiciary maintains a public web-based database, called CourtConnect, that includes an index of defendants by name and date of birth and lists all arrests followed by prosecution and court actions through final sentence. The criminal history information includes all charges filed in any Rhode Island court for the last 25 years.

Two researchers independently coded offender data (Differential Sentencing Data - Persons, n=982) available on CourtConnect. Coders then determined whether the defendants were prosecuted for the charges brought against them (Differential Sentencing Data - Offenses, n=6,649). Offenses that were not prosecuted were differentiated from offenses that were prosecuted. Each charge was classified as domestic violence or non-domestic violence as defined by state statute.

Assessing Consistency and Fairness in Sentencing in Michigan, Minnesota, and Virginia, 2001-2002, 2004 (ICPSR 22642)

Released/updated on: 2009-11-30
Geographic coverage: United States, Minnesota, Virginia, Michigan
Time period: 2001-07-01--2002-06-30, 2001-07-01--2002-06-30
The purpose of the study was to evaluate the integrity of sentencing outcomes under alternative state guideline systems and to investigate how this variation in structure impacted actual sentencing practice. The research team sought to address the question, to what extent do sentencing guidelines contribute to the goals of consistency, proportionality, and a lack of discrimination. The National Center for State Courts conducted an examination of sentencing patterns in three states with substantially different guidelines systems: Minnesota, Michigan, and Virginia. The three states vary along critical dimensions of the presumptive versus voluntary nature of guidelines as well as basic mechanics. There are differences in the formal design, administration, and statutory framework of the Michigan, Minnesota, and Virginia sentencing systems. For the 2004 Michigan Sentencing Outcomes Data (Part 1), the Michigan Department of Corrections Offender Management Network Information System (OMNI) provided sentencing guideline data for 32,754 individual offenders sentenced during calendar year 2004. For the 2002 Minnesota Sentencing Outcomes Data (Part 2), the Minnesota Sentencing Commission provided data for 12,978 individual offenders sentenced in calendar year 2002. The Virginia Sentencing Commission provided the Fiscal Year 2002 Virginia Assault Sentencing Outcomes Data (Part 3) and the Fiscal Year 2002 Virginia Burglary Sentencing Outcomes Data (Part 4). The Assault and Burglary/Dwelling crime groups have 1,614 and 1,743 observations, respectively. Variables in the four datasets are classified into the broad categories of conviction offense severity, prior record, offense seriousness, grid cell type, habitual/modifiers, departure, and extra guideline variables.

Augmented Federal Probation, Sentencing, and Supervision Information System, 1985 (ICPSR 9664)

Released/updated on: 2006-01-12
Geographic coverage: United States
The United States Sentencing Commission, established by the 98th Congress, is an independent agency in the judicial branch of government. The Commission recommends guidelines prescribing the appropriate form and severity of punishment for offenders convicted of federal crimes. These data were collected to determine whether sentencing disparities existed and whether the guidelines were adequate. Basic information in the collection includes a description of the offense, characterization of the defendant's background and criminal record, method of disposition of the case, and sentence imposed. Felony and misdemeanor cases are included while petty offense cases are excluded. Three types of additional information were used to augment the existing data: (1) more detailed offense and offender characteristics identified by the United States Sentencing Commission but coded by federal probation officers, (2) actual time served in prison from the SENTRY data file of the United States Bureau of Prisons, and (3) information necessary to estimate prospective release dates from the hearing files of the United States Parole Commission. The unit of analysis is the defendant.

Availability and Use of Intermediate Sanctions by Judges and Corrections Professionals in the United States, 1994 (ICPSR 6788)

Released/updated on: 2013-05-15
Geographic coverage: United States
This survey is part of a larger project designed to explore ways to increase the availability and use of intermediate sanctions (IS) on a national level without jeopardizing public safety. A model for an Intermediate Punishment System is suggested. The survey was undertaken to ascertain attitudes and practices concerning IS for three groups: state and federal judges (Part 3), correctional system administrators responsible for community corrections in their state or jurisdiction (Part 1), and program directors who actually operated community programs (Part 2). The units of analysis were intermediate sanctions/programs operating in jurisdictions across the United States. Data were collected on the availability and frequency of use of IS, as well as costs, client/staffing ratios, use of rehabilitative programming, respondents' opinions concerning the field's needs, and program eligibility criteria. Information was also gathered on how decisions were made to place offenders into the various programs, program outcome and whether the program was viewed as being successful (and how this was measured), and types of new programs needed.

Breaking the Cycle of Drugs and Crime in Birmingham, Alabama, Jacksonville, Florida, and Tacoma, Washington, 1997-2001 (ICPSR 3928)

Released/updated on: 2006-03-30
Geographic coverage: Tacoma, United States, Alabama, Florida, Birmingham, Jacksonville, Washington
Time period: 1997-01-01--2001-01-01
This study was an evaluation of the Breaking the Cycle (BTC) demonstration projects conducted in Birmingham, Alabama, Jacksonville, Florida, and Tacoma, Washington, between 1997 and 2001. The BTC demonstrations tested the feasibility and impact of systemwide interventions to reduce drug use among offenders by identifying and intervening with drug-involved felony defendants. This study contains data collected as part of the impact evaluation of BTC, which was designed to test the hypotheses that BTC reduced criminal involvement, substance abuse, and problems related to the health, mental health, employment, and families of felony drug defendants in the demonstration sites. The evaluation examined the relationship between changes in these areas and characteristics of the participants, the kinds and levels of services and supervision they received, and perceptions of defendants about the justice system's handling of their cases. It also assessed how BTC affected case handling and the length of time required to reach a disposition, the number of hearings, and the kinds of sentences imposed. The impact evaluation was based on a quasi-experimental comparison of defendants in BTC with samples of similar defendants arrested in the year before BTC implementation. Interviews were conducted with sample members and additional data were gathered from administrative records sources, such as the BTC programs, arrest records, and court records.

California Vital Statistics and Homicide Data, 1990-1999 (ICPSR 3482)

Released/updated on: 2006-02-17
Geographic coverage: United States, California
Time period: 1990-01-01--1999-01-01
This data collection resulted from the project "Linked Homicide File for 1990-1999," which was conducted by the California Department of Health Services (CDHS), Epidemiology and Prevention for Injury Control Branch, for the purpose of studying homicide and providing evidence for the development of strategies to reduce homicide in California. The researchers combined the strengths of law enforcement reporting and medical reporting in one dataset. The homicide data contain information on victims and circumstances of the 34,542 homicides investigated by law enforcement agencies in California for the period 1990 to 1999. The data are Supplementary Homicide Reports (SHR), which are received monthly by the Department of Justice from all local California law enforcement agencies as part of the national Uniform Crime Reporting program (UNIFORM CRIME REPORTS [UNITED STATES]: SUPPLEMENTARY HOMICIDE REPORTS, 1976-1999 [ICPSR 3180]). The researchers linked the SHRs to the CDHS vital statistics mortality data, which contain the death records provided by the medical examiner or coroner of each county after investigation of the death. Variables include total number of offenders involved, weapon used in the homicide, county of the victim's residence, location and date of the incident, date of death, cause of death, date of arrest for the suspect, and whether supplemental homicide report matched the death record. Demographic data include age, sex, and race of the victim and the suspect, relationships between the suspect and the victim, and the victim's marital status.

Case Outcomes Following Investigative Interviews of Suspected Victims of Child Sexual Abuse in Salt Lake City and County, Utah, 1994-2000 (ICPSR 27721)

Released/updated on: 2010-08-10
Geographic coverage: United States, Salt Lake City, Utah
Time period: 1994-01-01--2000-01-01
The purpose of this study was to examine whether the National Institute of Child Health and Human Development (NICHD) Investigative Interview Protocol impacted child sexual abuse case outcomes within the justice system. The researchers coded information from child protection and police reports, Children's Justice Center (CJC) intake forms, and the CJC electronic database to create a dataset on 1,280 alleged child sexual abuse cases involving children interviewed in Salt Lake County, Utah, between 1994 and 2000. Specifically, the research team gathered case characteristics and case outcomes data on 551 alleged child sexual abuse cases in which investigative interviews were conducted from 1994 to mid-September 1997 before the NICHD protocol was implemented, and 729 alleged child sexual abuse cases in which investigative interviews were conducted from mid-September 1997 to 2000 after the implementation of the NICHD protocol, so that pre-NICHD protocol and NICHD protocol interview case outcomes could be compared. The same police detectives conducted both the pre-NICHD protocol interviews and the NICHD protocol interviews. The dataset contains a total of 116 variables pertaining to cases of suspected child abuse. The major categories of variables include demographic data on the suspected child victim and on the suspected perpetrator, on case characteristics, on case outcomes, and on time delays.

Released/updated on: 2006-03-30
Geographic coverage: United States, Missouri, Phoenix, St. Louis, Arizona, Philadelphia, Pennsylvania
Time period: 1980-01-01--1994-01-01
This study sought to assess changes in the volume and types of homicide committed in Philadelphia, Phoenix, and St. Louis from 1980 to 1994 and to document the nature of those changes. Three of the eight cities originally studied by Margaret Zahn and Marc Riedel (NATURE AND PATTERNS OF HOMICIDE IN EIGHT AMERICAN CITIES, 1978 [ICPSR 8936]) were revisited for this data collection. In each city, police records were coded for each case of homicide occurring in the city each year from 1980 to 1994. Homicide data for St. Louis were provided by the St. Louis Homicide Project with Scott Decker and Richard Rosenfeld as the principal investigators. Variables describing the event cover study site, year of the case, date and time of assault, location of fatal injury, method used to kill the victim, and circumstances surrounding the death. Variables pertaining to offenders include total number of homicide and assault victims, number of offenders arrested, number of offenders identified, and disposition of event for offenders. Variables on victims focus on whether the victim was killed at work, if the victim was using drugs or alcohol, the victim's blood alcohol level, and the relationship of the victim to the offender. Demographic variables include age, sex, race, and marital status of victims and offenders.

Child Abuse, Neglect, and Violent Criminal Behavior in a Midwest Metropolitan Area of the United States, 1967-1988 (ICPSR 9480)

Released/updated on: 2006-01-12
Geographic coverage: United States
Time period: 1967-01-01--1988-01-01
These data examine the relationships between childhood abuse and/or neglect and later criminal and violent criminal behavior. In particular, the data focus on whether being a victim of violence and/or neglect in early childhood leads to being a criminal offender in adolescence or early adulthood and whether a relationship exists between childhood abuse or neglect and arrests as a juvenile, arrests as an adult, and arrests for violent offenses. For this data collection, adult and juvenile criminal histories of sampled cases with backgrounds of abuse or neglect were compared to those of a matched control group with no official record of abuse or neglect. Variables contained in Part 1 include demographic information (age, race, sex, and date of birth). In Part 2, information is presented on the abuse/neglect incident (type of abuse or neglect, duration of the incident, whether the child was removed from the home and, if so, for how long, results of the placement, and whether the individual was still alive). Part 3 contains family information (with whom the child was living at the time of the incident, family disruptions, and who reported the abuse or neglect) and data on the perpetrator of the incident (relation to the victim, age, race, sex, and whether living in the home of the victim). Part 4 contains information on the charges filed within adult arrest incidents (occasion for arrest, multiple counts of the same type of charge, year and location of arrest, and type of offense or charge), and Part 5 includes information on the charges filed within juvenile arrest incidents (year of juvenile charge, number of arrests, and type of offense or charge). The unit of analysis for Parts 1 through 3 is the individual at age 11 or younger, for Part 4 the charge within the adult arrest incident, and for Part 5 the charge within the juvenile arrest incident.

Convenience Store Crime in Georgia, Massachusetts, Maryland, Michigan, and South Carolina, 1991-1995 (ICPSR 2699)

Released/updated on: 2006-03-30
Geographic coverage: United States, Massachusetts, Georgia, Maryland, South Carolina, Michigan
Time period: 1991-01-01--1995-01-01
For this study, convenience store robbery victims and offenders in five states (Georgia, Massachusetts, Maryland, Michigan, and South Carolina) were interviewed. Robbery victims were identified by canvassing convenience stores in high-crime areas, while a sample of unrelated offenders was obtained from state prison rolls. The aims of the survey were to address questions of injury, to examine store characteristics that might influence the rate of robbery and injury, to compare how both victims and offenders perceived the robbery event (including their assessment of what could be done to prevent convenience store robberies in the future), and to identify ways in which the number of convenience store robberies might be reduced. Variables unique to Part 1, the Victim Data file, provide information on how the victim was injured, whether hospitalization was required for the injury, if the victim used any type of self-protection, and whether the victim had been trained to handle a robbery. Part 2, the Offender Data file, presents variables describing offenders' history of prior convenience store robberies, whether there had been an accomplice, motive for robbing the store, and whether various factors mattered in choosing the store to rob (e.g., cashier location, exit locations, lighting conditions, parking lot size, the number of clerks working, weather conditions, the time of day, and the number of customers in the store). Found in both files are variables detailing whether a victim injury occurred, use of a weapon, how each participant behaved, perceptions of why the store was targeted, what could have been done to prevent the robbery, and ratings by the researchers on the completeness, honesty, and cooperativeness of each participant during the interview. Demographic variables found in both the victim and offender files include age, gender, race, and ethnicity.

Crime Control Effects of Prosecuting Intimate Partner Violence in Hamilton County, Ohio, 1993-1998 (ICPSR 25929)

Released/updated on: 2011-06-27
Geographic coverage: United States, Ohio
Time period: 1993-01-01--1998-01-01
The purpose of this research was to improve understanding of the conditions under which criminal sanctions do and do not reduce repeat violence between intimate partners. This study involved repeated reading and close inspection of four documents in order to compare and contrast the multivariate analyses reported by John Wooldredge and Amy Thistlethwaite (RECONSIDERING DOMESTIC VIOLENCE RECIDIVISM: INDIVIDUAL AND CONTEXTUAL EFFECTS OF COURT DISPOSITIONS AND STAKE IN CONFORMITY IN HAMILTON COUNTY, OHIO, 1993-1998 [ICPSR 3013]). The first part of this study's design involved the detailed literature review of four Wooldredge and Thistlethwaite publications between the years 1999 and 2005. The second element of the study's design required researchers to gain a detailed understanding of the archived data using the documentation provided by Wooldredge. The third element of the study's secondary analysis research design involved using the identified variables to reproduce the multivariate empirical findings about the effects of sanctions, stakes, and social context on repeat offending. These findings were presented in a series of tables in the four Wooldredge and Thistlethwaite publications. After numerous iterations of reading reports and documentation and exploring alternative measures and methods, researchers produced a report detailing their ability to reproduce Wooldredge and Thistlethwaite's descriptive measures. This study's design called for using explicit criteria for determining the extent to which Wooldredge and Thistlethwaite's findings could be reproduced. Researchers developed and applied three criteria for making that determination. The first was a simple comparison of the regression coefficients and standard errors. The second criterion was a determination of whether the reproduced results conformed to the direction and statistical significance levels of the original analyses. The third criterion was to apply a statistical test to assess the significance of any differences in the sizes of the original and the reproduced coefficients. The data archived by Wooldredge provided seven dichotomous measures of criminal sanctions (no charges filed, dismissed, acquitted, a treatment program, probation only, jail only, and a combination of probation and jail). Part of the design of this study was to go beyond reproducing Wooldredge and Thistlethwaite's approaches and to reformulate the available measures of criminal sanctions to more directly test the prosecution, conviction, and sentence severity hypotheses. The researchers produced these tests by constructing three new measures of criminal sanctions (prosecution, conviction, and sanction severity) and testing each of them in separate multivariate models. The Part 1 (Hamilton County, Ohio, Census Tract Data) data file contains 206 cases and 35 variables. The Part 2 (Neighborhood Data) data file contains 47 cases and 12 variables. The variables in Part 1 (Hamilton County, Ohio, Census Tract Data) include a census tract indicator, median household income of tract, several proportions such as number of college graduates in the tract and corresponding Z-scores, a regression factor score for analysis 1, a socio-economic factor, a census tract number for the city of Cincinnati, Ohio, and a Cincinnati neighborhoods indicator. Variables in Part 2 (Neighborhood Data) include a neighborhood indicator, average age in the neighborhood, demographic proportions such as proportion male in the neighborhood and proportion of college graduates in the neighborhood, and a social class factor.

Criminal Careers and Crime Control in Massachusetts [The Glueck Study]: A Matched-Sample Longitudinal Research Design, Phase I, 1939-1963 (ICPSR 9735)

Released/updated on: 2005-11-04
Geographic coverage: United States, Massachusetts
The relationship between crime control policies and fundamental parameters of the criminal career, such as career length, participation in offenses, and frequency and seriousness of offenses committed, is examined in this data collection. The investigators coded, recoded, and computerized parts of the raw data from Sheldon and Eleanor Glueck's three-wave, matched sample study of juvenile and adult criminal behavior, extracting the criminal histories of the 500 delinquents (officially defined) from the Glueck study. Data were originally collected by the Gluecks in 1940 through psychiatric interviews with subjects, parent and teacher reports, and official records obtained from police, court, and correctional files. The subjects were subsequently interviewed again between 1949 and 1965 at or near the age of 25, and again at or near the age of 32. The data coded by Laub and Sampson include only information collected from official records. The data address in part (1) what effects probation, incarceration, and parole have on the length of criminal career and frequency of criminal incidents of an offender, (2) how the effects of criminal control policies vary in relation to the length of sentence, type of offense, and age of the offender, (3) which factors in criminal control policy correlate with criminal career termination, (4) how well age of first offense predicts the length of criminal career, and (5) how age of offender relates to type of offense committed. Every incident of arrest up to the age of 32 for each respondent (ranging from 1 to 51 arrests) is recorded in the data file. Variables include the dates of arrest, up to three charges associated with the arrest, court disposition, and starting and ending dates of probation, incarceration, and parole associated with the arrest.

Delinquency in a Birth Cohort in Wuchang District, Wuhan, China, 1973-2000 (ICPSR 3751)

Released/updated on: 2006-03-30
Geographic coverage: China (Peoples Republic), Global
Time period: 1973-01-01--2000-01-01
This study was designed by American criminologist Marvin Wolfgang as a replication of his DELINQUENCY IN A BIRTH COHORT studies conducted in Philadelphia, Pennsylvania (ICPSR 7729 and ICPSR 9293). The focus of the study is a cohort of all persons born in 1973 in the Wuchang District of the city of Wuhan. This district was selected because it was a populous commercial and residential area. The cohort birth year was chosen to reflect the impact of major economic and social changes in China. Data include interviews with all known criminal offenders as of 1990 and with a matched comparison sample. Additional residential, demographic, and updated criminal history data as of 2000 were collected on all persons born in the 1973 Wuchang District cohort.

Desistance from Crime Over the Life Course, South Carolina, 2005-2017 (ICPSR 36987)

Released/updated on: 2021-03-30
Geographic coverage: United States, South Carolina
Time period: 2005-01-01--2017-01-01

The current study focused on 479 men and women from South Carolina who were enrolled as participants in the Serious and Violent Offender Reentry Initiative (SVORI) multi-site program evaluation shortly before prison release in 2004 or 2005. The original SVORI data suggested that the South Carolina respondents were similar to the multi-site sample with "committed to not going back to prison" as the most common reason for desisting and using drugs or alcohol as the most common reason for persisting. The goals of the current study were to (1) update information on the current status of these individuals across multiple domains (e.g., housing, employment, substance use); (2) gather additional administrative recidivism data to examine long-term offending; and (3) acquire information about the factors individuals associated with their decisions to desist from criminal activity, as well as circumstances associated with renewed criminal activity or desistence. Interviews were conducted with those that the study team were able to locate and additional administrative arrest and incarceration data were acquired for the full sample, providing recidivism follow-up over at least a 10-year period.

Official administrative data were obtained from the South Carolina Law Enforcement Division (rearrests) and South Carolina Department of Corrections (reincarcerations). Arrest data span the entire arrest history (from first arrest through December 2015); reincarceration data span the period between the SVORI study prison release in 2005 and 2006 through June 2014. These data were obtained for the full sample of 479 South Carolina SVORI participants.

Three components of interview data were collected.

  • Desistance study interview data: 1 wave of in-person interviews was conducted with 208 study subjects who consented to participate in an interview. The research team used computer-assisted personal interviewing (CAPI) to administer the survey, and interviews were conducted from September 2016 through March 2017.
  • Life event data: The Life Events Calendar (LEC) is a tool used in qualitative and quantitative research to gather retrospective information about a person's life, experiences, and history. The approach is based on autobiographical memory and how entering events on a calendar or page help facilitate memory recall. LECs typically encompass periods of 5 years or less; this study's LEC covered a 10- to 12-year span to allow analysis since last contact with the study cohort. Data were collected from the 208 subjects who consented to be interviewed.
  • SVORI interview data: This inventory includes files with select baseline and outcome data (e.g., self-reported employment, drug use, criminal behavior) for desistance study subjects who responded to follow-up interviews at Wave 2 (3-month), Wave 3 (9-month), and Wave 4 (15-month).

This collection of administrative and interview data is organized into 14 data parts. Demographic data includes information on age, gender, race, and education.

Developing Methods for Assessing Outcomes of Law and Policy on Drug Trafficking Offenders, Organizations, and Criminal Justice Responses, United States, 2000-2018 (ICPSR 38441)

Released/updated on: 2024-02-27
Geographic coverage: Tacoma, Seattle, United States, California, Bellevue, Washington
Time period: 2000-01-01--2018-12-31

This project sought to gather and analyze data on the effects of marijuana legalization from primary and secondary data sources that are both local and national in scope, and at both the individual and aggregate level. Since 1996, 37 states have passed statutes legalizing marijuana for medical and/or recreational use, while it has remained illegal under federal law. Jurisdictional and temporal variation in law creates a complex environment and substantial challenges for police and prosecutors charged with enforcement, and little is known about the justice system processing, public safety, and public health outcomes of evolving laws and policies.

Secondary criminal justice and public health data were gathered from federal, state, and local sources. Each source has a sufficiently long time series to provide statistical power and to allow for sometimes gradual implementation. The design exploits geographic and temporal variation in the implementation of marijuana law, using a difference-in-differences design that compares outcomes in states which implemented the policies with states that did not, before and after implementation.

Domestic Violence and Substance Abuse Among the Arrestee Population in Albuquerque, New Mexico, 1999-2001 (ICPSR 3585)

Released/updated on: 2003-06-25
Geographic coverage: United States, New Mexico
Time period: 1999-01-01--2001-01-01
The focus of this study was to examine levels of aggressive behavior during incidents of domestic violence in relation to self-reported drug and alcohol use among an arrestee population from Bernalillo County in Albuquerque, New Mexico. The research questions motivating this project were: (1) Are acts of domestic violence committed while the offender is taking illicit psychoactive substances, as ascertained by self-reports? (2) For those individuals with domestic violence charges, do urinalyses conducted within 48 hours of an individual's arrest indicate the recent use of a psychoactive substance? (3) Which substances are most prevalently associated with incidents of domestic violence? (4) Is there a difference in levels of aggressive behavior that is dependent on the individual? (5) Does the severity of domestic violence increase with the presence of psychoactive substances? (6) What differences (if any) exists between batterers who take psychoactive substances and batterers who do not? The data for this research were collected in conjunction with the National Institute of Justice's Arrestee Drug Abuse Monitoring (ADAM) programs. The domestic violence survey addendum was administered to all arrestees from Bernalillo County in Albuquerque, New Mexico, who had completed the ADAM interview and provided a urine specimen and were willing to answer additional questions concerning domestic violence. Variables from the ADAM instruments were comprised of demographic data on each arrestee, calendar of admissions to drug treatment-related programs, data on dependence and abuse, drug market and use data, and urine test results. Variables from the domestic violence addendum include demographics on the intimate partner, whether specific physical events occurred, whether specific injuries had been sustained by both arrestee and partner, and the specific circumstances surrounding the physical abuse event.

Domestic Violence Experiment in King's County (Brooklyn), New York, 1995-1997 (ICPSR 4307)

Released/updated on: 2006-08-01
Geographic coverage: United States, Brooklyn, New York (state)
Time period: 1995-02-01--1997-09-01
The researchers sought to add to the incipient literature on randomized studies of batterer treatment, by conducting an experimental study that compared batterers assigned to treatment to batterers assigned to a community service program irrelevant to the problem of violence. The study was conducted using a true experimental design and consisted of 376 spousal assault cases drawn from the Kings County (New York) Criminal Court which were adjudicated between February 19, 1995, and March 1, 1996. Batterers were mandated to attend a 40-hour batterer treatment program or to complete 40 hours of community service. The random assignment was made at sentencing, after all parties (judge, prosecutor, and defense) had agreed that batterer treatment was appropriate, the defendant agreed to treatment and was accepted by the Alternatives to Violence (ATV) program, and the program was available based on the random assignment process. Interviews were also conducted with both the batterer and the victim at sentencing as well as 6 months post-sentence and 12 months post-sentence. These interviews collected data in areas regarding demographics (first interview only), recidivism, beliefs about domestic violence, conflict management strategies, locus of control, and for victims, self esteem. Administrative records were also used to obtain data regarding any new crimes committed.

Geographic coverage: United States, United Kingdom, Australia

The objective of this study was to systematically review and statistically synthesize all available research that, at a minimum, compared participants in a restorative justice program to participants processed in a more traditional way using meta-analytic methods. Ideally, these studies would include research designs with random assignment to condition groups, as this provides the most credible evidence of program effectiveness.

The systematic search identified 99 publications, both published and unpublished, reporting on the results of 84 evaluations nested within 60 unique research projects or studies. Results were extracted from these studies, related to delinquency, non-delinquency, and victim outcomes for the youth and victims participating in these programs.

Effects of Short-Term Batterer Treatment for Detained Arrestees in Sacramento County, California, 1999-2000 (ICPSR 4383)

Released/updated on: 2007-02-13
Geographic coverage: United States, California
Time period: 1999-01-01--2000-01-01
This study evaluated the effects of a program for detained arrestees developed by the Sacramento Sheriff's Department. The program was set up as an early intervention program to provide domestic violence (DV) education for arrestees during their time of detention before going to court. This evaluation used an experimental design. The researchers randomly assigned 629 batterers to either the batterer treatment wing of the jail or to a no-treatment control group in another wing of the jail. Interviews were conducted with the batterers and victims shortly after the arrest that placed the batterer in the Sacramento jail (Parts 1 and 2) and again six months after the intervention or control condition was concluded (Parts 3 and 4). Official police arrest data on recidivism were also collected post-arrest (Part 5). Interviews were conducted over the phone, except for the baseline batterer interviews that were done in the jail, and for those who were not available for interviewing, over the phone. Activities of the batterer treatment program included: mandatory detention in a special DV jail wing supervised by correction officers who had received special DV training, batterer educational workshops, daily Twelve-Step Drug/Alcohol addiction support groups, and strict regulations on television watching (special nonviolent educational programs were the only available programs). Batterer education classes were held daily, and the research team checked attendance logs. The arrestees were required at least to attend the program classes and Narcotics Anonymous/Alcoholics Anonymous groups and sit quietly. For the control group, participants were assigned to the regular part of the jail and received the usual incarceration experience of persons detained in the Sacramento County Jail (including no treatment services). Official police arrest data on recidivism were analyzed for up to one year post-arrest (Part 5). Treatment implementation data (Part 6), which records the frequency of the batterer's attendance in the various treatment programs offered in the special DV jail wing, and variables used in the analysis for the project's final report (Part 7) are also available with this collection. In addition to general demographic variables such as age, race, religion, source of income, and employment situation, specific variables are gathered for specific datasets. Variables collected in Parts 1 and 2 (Batterer and Victim Baseline Data) include information regarding whether or not the batterer was in the treatment or control group, the relationship between the batterer and victim, and types of injuries the victim received. Parts 3 and 4 (Batterer and Victim Six-Month Data) contain variables related to employment and living situation, as well as any additional assistance either party received since the arrest event. Variables in Part 5 (Tracking Database) include the date, location, and length of interviews. Part 6 (Treatment and Implementation Data) contains variables related to the different programs the batterer in the experimental group may have participated in. The variables for Part 7 (Supplemental Final Report Variables) include information about the study participants such as whether all four interviews were completed and the presence of any new domestic violence charges.

Electronic Monitoring of Nonviolent Convicted Felons: An Experiment in Home Detention in Marion County, Indiana, 1986-1988 (ICPSR 9587)

Released/updated on: 2006-01-12
Geographic coverage: Indiana, United States
Time period: 1986-11-01--1988-12-01
The purpose of the study was to provide information about home detention monitoring systems and to evaluate their effectiveness. The principal investigators sought to determine (1) whether electronic monitoring systems relieved some of the burdens associated with manual monitoring of home detention, such as making telephone calls and field visits, (2) how home detention affected the lifestyles of offenders, (3) whether the methods of monitoring influenced offender behavior during the program, (4) how electronic monitoring differed from manual monitoring in terms of supervision of the offenders, (5) how offenders reacted to electronic monitoring, (6) how offenders' families reacted to electronic monitoring, and (7) whether the method of monitoring influenced the probability of an arrest or subsequent contact with the criminal justice system after release from the program. Part 1 contains demographic information, such as age, race, marital status, number of children, living arrangements, employment, and education for each offender. Also included is information on the offense leading to the current case, including numbers and types of charges and convictions for both felonies and misdemeanors, recommendations and judicial disposition for the current case, and information on the criminal history of the offender. Part 2 contains data from the intake interview with the offender, such as information on the offender's family, living arrangements, education, employment, past alcohol and drug use, and expectations for the home detention program and monitoring procedures. Part 3 contains information collected in the exit interview and is similar in content to Part 2. Part 4 contains information on the program delivery (type of release from the program, violations of the program, results of tests for alcohol and drug use, errand time, payment, contacts with offenders, and the characteristics and results of the contacts with electronically monitored offenders). Part 5 is a check of criminal histories of offenders for at least one year after their release from the program.

Evaluating a Driving While Intoxicated (DWI) Night Drug Court in Las Cruces, New Mexico, 1997-1998 (ICPSR 3186)

Released/updated on: 2006-01-18
Geographic coverage: Las Cruces, United States, New Mexico
The purpose of this study was twofold. First, researchers wanted to assess the benefits of the driving while intoxicated (DWI) drug court established in the Las Cruces, New Mexico, Municipal Court in an effort to determine its future viability. This was accomplished by examining the behaviors and attitudes of three groups of convicted drunk-drivers and determining the extent to which these groups were different or similar. The three groups included: (1) non-alcoholic first- and second-time offenders (non-alcoholic offenders), (2) alcoholic first- and second-time DWI offenders (alcoholic offenders), and (3) chronic three-time (or more) DWI offenders (chronic offenders). The second purpose of this study was to explore police officers' attitudes toward court-based treatment programs for DWI offenders, while examining the distinguishing characteristics between police officers who support court-based programs for drunk drivers and those who are less likely to support such sanctions. Data for Part 1, Drug Court Survey Data, were collected using a survey questionnaire distributed to non-alcoholic, alcoholic, and chronic offenders. Part 1 variables include blood alcohol level, jail time, total number of prior arrests and convictions, the level of support from the respondents' family and friends, and whether the respondent thought DWI was wrong, could cause injury, or could ruin lives. Respondents were also asked whether they acted spontaneously in general, took risks, found trouble exciting, ever assaulted anyone, ever destroyed property, ever extorted money, ever sold or used drugs, thought lying or stealing was OK, ever stole a car, attempted breaking and entering, or had been a victim of extortion. Demographic variables for Part 1 include the age, gender, race, and marital status of each respondent. Data for Part 2, Police Officer Survey Data, were collected using a survey questionnaire designed to capture what police officers knew about the DWI Drug Court, where they learned about it, and what factors accounted for their attitudes toward the program. Variables for Part 2 include police officers' responses to whether DWI court was effective, whether DWI laws were successful, the perceived effect of mandatory jail time versus treatment alone, major problems seen with DWI policies, if DWI was considered dangerous, and how the officer had learned or been briefed about the drug court. Other variables include the number of DWI arrests, and whether respondents believed that reforms weaken police power, that DWI caused more work for them, that citizens have bad attitudes, that the public has too many rights, and that stiffer penalties for DWI offenders were more successful.

Geographic coverage: United States, Florida
Time period: 1991-01-01--1997-01-01
This study was undertaken to investigate the relationship, if any, between drug treatment and success or failure of drug-involved offenders on probation/community supervision. Further, the researchers sought to evaluate the outcomes of drug-involved offenders admitted to (1) secure residential substance abuse treatment (RSAT) programs, (2) non-secure residential drug treatment programs, (3) non-residential drug treatment programs, and (4) no drug treatment programs. Data were collected from administrative records provided by the Florida Department of Corrections, specifically case history records of offenders admitted to supervision in the community from July 1, 1991, through June 30, 1997. Part 1 is comprised of all cases admitted to community supervision between July 1, 1991, and June 30, 1993 (fiscal years 1991 and 1992) and treated in a secure residential drug treatment program. Part 2 is comprised of all cases admitted to community supervision from July 1, 1991, through June 30, 1995, receiving treatment in a non-secure residential drug treatment program. Part 3 contains data on offenders admitted to non-residential drug treatment programs, whose community supervision admissions were between July 1, 1991, and June 30, 1993. Part 4 contains data on offenders admitted to non-residential drug treatment programs, whose community supervision admissions were between July 1, 1993, and June 30, 1995 (fiscal years 1993 and 1994). Part 5 contains data on cases admitted to community supervision between July 1, 1991, and June 30, 1993, who did not receive drug treatment of any kind. Cases admitted to community supervision between July 1, 1993, and June 20, 1995, receiving no drug treatment are contained in Part 6. Each supervision admission record contains a history of subsequent court actions that were complete through December 31, 1997. Variables for all parts include population estimates, unemployment rates, population by age-specific categories, violent and nonviolent index offenses, per capita personal income, clearance rates, split sentence flag, primary offense disposition, primary offense felony level, current commitment years supervised, supervision type, whether current offense included a drug charge, number of prior supervision terms, number of prior commitments, reasons for failure, treatment facility code, number of drug sale/traffic offenses, outcome of supervision period, and reasons for prison intake. Demographic variables include race and gender.

An Evaluation of 24/7 Sobriety Program Implementation, North Dakota, 2001-2015 (ICPSR 37369)

Released/updated on: 2024-01-30
Geographic coverage: United States, North Dakota
Time period: 2001-01-01--2015-01-01

The 24/7 Sobriety Program was created in South Dakota in 2005 to reduce repeat driving under the influence (DUI) offenses and jail populations, with the idea being to compel DUI defendants to abstain from alcohol and/or drug use for a period of time (Jackley and Long, 2017). The evidence-based program works as a continuous monitoring program where DUI defendants submit to scheduled and/or random testing for controlled substances. If a participant does not appear for testing or tests positive, they are subject to swift, certain, proportional, and consistent sanctions (e.g., immediate short-term incarceration). Compliant participants receive immediate positive feedback. As of March 2017, 24/7 Sobriety programs were authorized in 9 states: South Dakota, North Dakota, Montana, Washington, Idaho, Wyoming, Wisconsin, Utah, and Alaska.

In this study, the research team examined the implementation of the 24/7 Sobriety program in South Dakota, Montana, North Dakota, Jacksonville (Duval County), Florida, and Yavapai County, Arizona. The researchers sought to answer questions about the program's mechanics and effectiveness across several states, and to illuminate what aspects of program delivery are central to achieving outcomes that are relevant to criminal justice researchers and practitioners, such as recidivism, public safety, and alternatives to incarceration. This multi-site, mixed-methods evaluation consisted of secondary analysis of administrative program data and arrest records from North Dakota, case studies of pilot programs in Jacksonville and Yavapai County involving stakeholder interviews and on-site observations, and secondary analysis of breathalyzer test results from South Dakota, North Dakota, and Montana.

The North Dakota 24/7 Sobriety implementation and outcomes data are a county-by-month panel of driving under the influence of alcohol (DUI) arrest events compiled from state Department of Transportation reports and a set of variables based on restricted 24/7 Sobriety program data describing program implementation by county in North Dakota from 2008 to 2015, with pre-program arrest data dating back to 2001.

Evaluation of Day Fines in Maricopa County, Arizona, 1991-1993 (ICPSR 2024)

Released/updated on: 2006-03-30
Geographic coverage: United States, Arizona
Time period: 1991-01-01--1993-01-01
This study sought to evaluate how well day fines work as an intermediate sanction. Day fines are a structured approach to imposing fines that considers both the offender's ability to pay and the severity of the offense. The program involves two steps: (1) a determination of the number of fine units for an offense, based on the severity of the offense, and (2) a valuation of fine units, based on the offender's net daily income, hence the name "day fines". While four jurisdictions participated in the day fines evaluation, only the site in Maricopa County, Arizona, was structured in such a way to allow for a quasi-experimental research design. Therefore, this collection only contains data from the Financial Assessment Related to Employability (FARE) day fines program in Maricopa County. The FARE program was started in 1991 and targeted felony offenders with little need for supervision or treatment -- in other words, the low risk-low need defendant. The intent of the program was to draw clients from the population of offenders who would traditionally receive routine probation, thus serving as an intermediate sanction between routine and summary probation. The major research strategy was to consider the FARE-sentenced offenders as the experimental group and to construct a similar comparison group out of the offenders sentenced by non-day fines judges. The design involved three major steps: (1) identification of 1991 and 1992 defendants who received a FARE sentence, (2) screening of sentenced defendants in non-FARE courts using FARE eligibility criteria to match the FARE participants, and (3) coding background and 12-month follow-up information for both FARE and comparison group offenders from probation and clerk files to record background information, monetary payments, and any technical violations and arrests occurring during the 12-month follow-up period. Variables in Part 1, Fines Paid Data, include the total amount of the fine and how much of the fine was applied to probation fees, reimbursement, restitution, and victim compensation. Part 2, Official Records Data, contains background information such as arrest history, marital status, education, drug use, and drug treatment. Additional information includes current arrest, recommended sentence, disposition, sentence imposed, employment and income, and risk/needs assessment. Six- and 12-month reviews collected data on supervisory status, technical violations, new arrests, payment enforcement, and payment term revisions.

Evaluation of Reentry-Based Restorative Justice: A Randomized Controlled Trial, Detroit, Michigan, 2019-2024 (ICPSR 39600)

Released/updated on: 2026-04-16
Geographic coverage: Detroit, United States, Michigan
Time period: 2019-01-01--2024-01-01

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.

Evaluation of the Implementation and Impact of the Massachusetts Intensive Probation Supervision Project, 1984-1985 (ICPSR 9970)

Released/updated on: 2006-01-18
Geographic coverage: United States, Massachusetts
Time period: 1984-01-01--1985-01-01
The purpose of this study was to evaluate the effectiveness of an Intensive Probation Supervision (IPS) program on high-risk offenders. The IPS program was characterized by four changes in usual procedures: (1) increased supervision, (2) risk/needs assessment for substance abuse, employment, and marital/family relationships, (3) stricter enforcement of probation, and (4) a four-stage revocation procedure for technical violations. The investigators also studied whether the additional caseload of the probation officers who implemented the IPS program reduced the number of supervision contacts with non-IPS probationers under normal minimum, moderate, and maximum supervision regimens. Offenders put on IPS probation in 1985 from 13 experimental courts were compared to high-risk offenders put on regular probation in the experimental courts in 1984, and to high-risk offenders on regular probation from 13 control courts for both 1984 and 1985. Data were derived from risk assessment forms, needs/strengths assessment forms, probation supervision records, and criminal history data obtained from the state's probation central field. For each offender, a full range of data were collected on (1) offender risk characteristics at initial, four-month, ten-month, and termination assessments, (2) offender needs characteristics at the same intervals, (3) probation officer/offender contact chronologies for the entire one-year follow-up period, and (4) offender prior criminal history and recidivism during a one-year follow-up period.

Evaluation of the Lexington County, South Carolina, Domestic Violence Court, 1997-2002 (ICPSR 4045)

Released/updated on: 2006-03-30
Geographic coverage: United States, South Carolina
Time period: 1997-01-01--2002-01-01
A separate Criminal Domestic Violence Court (CDVC) was established in Lexington County, South Carolina, in November 1999, to hold perpetrators of domestic violence accountable through increasing fines and jail time and to place a strong emphasis on mandatory batterer treatment programs. The CDVC was a specialized court that combined the efforts of law enforcement, judges, prosecutors, mental health professionals, and victim advocates to improve the safety of domestic violence victims and hold offenders accountable. The researchers undertook to evaluate and measure the extent to which the CDVC was successful in implementing its goals. For the process evaluation, interviews were conducted in 2002 with 50 victims and 50 defendants to examine their overall level of satisfaction with the court process, their perceptions of procedural justice, and their recommendations for improving the CDVC process. Interviews were conducted in person using structured questions immediately after a case was heard. The outcome evaluation consisted of two methods of data collection. A time series intervention analysis examined the monthly frequency of criminal domestic violence for the years 1997 through 2001. Criminal domestic violence cases were compared for the 34 months before the establishment of the CDVC (January 1997 to October 1999) and the first 26 months following its implementation (November 1999 to December 2001). Additionally, in an effort to examine the impact of the Lexington County Criminal Domestic Violence Court on individual case outcomes, a recidivism analysis was conducted on a random sample of 400 criminal domestic violence cases. Of these cases, 200 were control cases drawn from the Lexington County Sheriff's Department's arrest database for the period January 1997 to June 1999, and 200 were treatment cases comprised of domestic violence arrest cases that occurred between December 1999 and December 2000 and processed through CDVC. Variables in Part 1 (Victim Interview Data) and Part 2 (Defendant Interview Data) included responses to structured interview questions about the victims' and offenders' perceptions of various aspects of the court process, whether they felt treated with dignity and respect, and their overall impression of the CDVC response to domestic violence. Variables in Part 3 (Monthly Arrest Data) include court period, month, and frequency of monthly domestic violence arrests, monthly simple assault arrests, and monthly aggravated assault arrests. Variables in Part 4 (Recidivism Data) include race, age, and gender of offender, employment status, booking date, days in jail prior to trial, number of charges pending, number of prior domestic violence offenses, date of first re-arrest, recidivism within first year and a half, days free of arrest, if defendant was diverted to pretrial intervention, and the amount of the fine.

Evaluation of the Midtown Community Court in New York City, 1992-1994 (ICPSR 2311)

Released/updated on: 2006-03-30
Geographic coverage: New York City, United States, New York (state)
Time period: 1992-01-01--1994-01-01
In October 1993, the Midtown Community Court opened as a three-year demonstration project designed to forge links with the community in developing a problem-solving approach to quality-of-life offenses. The problems that this community-based courthouse sought to address were specific to the court's midtown New York City location: high concentration of quality-of-life crimes, broad community dissatisfaction with court outcomes, visible signs of disorder, and clusters of persistent high-rate offenders with serious problems, including addiction and homelessness. This study was conducted to evaluate how well the new court was able to dispense justice locally and whether the establishment of the Midtown Community Court made a difference in misdemeanor case processing. Data were collected at two time periods for a comparative analysis. First, a baseline dataset (Part 1, Baseline Data) was constructed from administrative records, consisting of a ten-percent random sample of all nonfelony arraignments in Manhattan during the 12 months prior to the opening of the Midtown Community Court. Second, comparable administrative data (Part 2, Comparison Data) were collected from all cases arraigned at the Midtown Court during its first 12 months of operation, as well as from a random sample of all downtown nonfelony arraignments held during this same time period. Both files contain variables on precinct of arrest, arraignment type, charges, bonds, dispositions, sentences, total number of court appearances, and total number of warrants issued, as well as prior felony and misdemeanor convictions. Demographic variables include age, sex, and race of offender.

Examination of Actuarial Offender-Based Prediction Assessments in Texas, 1993-1996 (ICPSR 20403)

Released/updated on: 2008-06-23
Geographic coverage: United States, Texas
Time period: 1993-01-01--1996-01-01
The purpose of this study was to provide a comprehensive assessment of the usefulness and effectiveness of prediction and classification of offenders under community supervision. A felony cohort data collection instrument was developed to test the validity of the Wisconsin Risk and Need Instrument in use in Texas, as well as to develop "better" predictor variables for a variety of dependent variables. Using the felony cohort data instrument, the Texas Department of Criminal Justice Community Justice Assistance Division (TDCJ-CJAD) collected detailed statewide information on 3,405 felony offenders placed on probation in Texas during October 1993. Specifically, the form was completed by a probation officer on all felony probation intakes at the time the initial case classification risk/needs assessment was conducted. Additionally, follow-up forms were developed and administered to track the offenders' progress at one year, two years, and three years. Variables include probationer information, current offense, criminal history, social history, substance abuse, probation sanctions, case classification risk items, and case classification need items. Additional variables include felony cohort one-year follow-up data form questions, felony cohort second-year follow-up data form questions, and felony cohort third-year follow-up data form questions.

This study is a secondary analysis of data from ICPSR Study Number 27101, Serious and Violent Offender Reentry Initiative (SVORI) Multi-site Impact Evaluation, 2004-2011 [United States]- specifically the adult male dataset -to examine the associations among child support obligations, employment and reentry outcomes. The study addressed the following research questions:

  1. Are the demographic, criminal justice and employment-related characteristics of incarcerated men with child support orders significantly different in any important way from incarcerated males without child support orders?
  2. Did SVORI clients receive more support and services related to child support orders and modification of debt after release from prison compared to non-SVORI participants?
  3. Does having legal child support obligations decrease the likelihood of employment in later waves, net of key demographic and criminal justice history factors?
  4. How does employment influence the relationship between child support debt and recidivism? and
  5. Is family instrumental support a significant predictor of reduced recidivism or increased employment in models assessing the relationship between child support obligations, employment and recidivism?

The study includes one document (Syntax_ChildSupport_Reentry_forICPSR_2012-IJ-CX-0012.docx) which contains SPSS and Stata syntax used to create research variables.

Examining Prosecutorial Decision-Making Across Federal District Courts, 2000-2009 [UNITED STATES] (ICPSR 34513)

Released/updated on: 2016-09-22
Geographic coverage: United States
Time period: 2000-01-01--2009-01-01

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 study utilized data from the Bureau of Justice Statistics on federal criminal case processing to study jurisdictional variations in prosecutorial decision-making outcomes. It linked information across multiple federal agencies in order to track individual offenders across the various stages of the federal justice system. Specifically, it combined arrest information from the United States Marshall's Service with charging information from the Executive and Administrative Offices of the United States Attorney and with sentencing information from the United States Sentencing Commission. These individual data were subsequently augmented with additional information on federal courts to examine contextual variations in charging decisions across federal jurisdictions.

There are three data files. Dataset 1 (Executive Office for United States Attorneys (EOUSA) and United States Marshals Service (USMS) Data) contains 88 variables and 284,869 cases. Dataset 2 (Administrative Office of the United States Courts (AOUSC) and United States Sentencing Commission (USSC) Data) contains 717 variables and 256,598 cases. Dataset 3 (United States District Court Characteristics Data) contains 6 variables and 89 cases.

Only Dataset 3 is being released as part of the available study materials. Datasets 1 and 2 can be re-created using the syntax files which are included in the study materials.

Examining Radicalization's Risk and Protective Factors: A Case-Control Study of Violent Extremists, Non-Violent Criminal Extremists, Non-Offending Extremists, and Regular Violent Offenders, United States, 1990-2020 (ICPSR 39026)

Released/updated on: 2025-08-14
Geographic coverage: United States
Time period: 1990-01-01--2020-01-01

This project examined the multidimensional pathways that led to extremism and extremist behaviors. The focus of the research was to examine risk and protective factors that either directly, or in combination, interact to increase or mitigate the risk of radicalization and terrorism.

This project comparatively examined the presence/absence of risk and protective factors across three groups:

  1. extremist individuals who committed ideologically motivated violent (fatal and non-fatal violent attacks) and nonviolent (financial) crimes
  2. extremists who did not break the law and only engaged in legal extremist activities
  3. persons who committed non-ideological motivated homicides and other violent attacks

Thus, researchers accomplished four major goals/objectives in this project. First, although there has been a good amount of radicalization and risk assessment-related research on risk and protective factors, researchers expanded this work with comparative analyses that have not been previously explored. Second, few studies compared violent or nonviolent criminal extremists to nonoffending extremists or other types of violent offenders. Third, researchers used a case-control approach to provide an empirically robust understanding of categorical differences across groups that have not yet been achieved. Fourth, researchers examined differences in participation of warning behaviors across the groups studied.

The data file includes 971 cases.

Experiment to Enhance the Reporting of Drug Use by Arrestees in Cleveland, Detroit, and Houston, 1997 (ICPSR 2890)

Released/updated on: 2001-04-12
Geographic coverage: Detroit, United States, Texas, Ohio, Cleveland, Michigan, Houston
Time period: 1997-07-01--1997-11-01
This project involved an experiment conducted in three Drug Use Forecasting (DUF) [DRUG USE FORECASTING IN 24 CITIES IN THE UNITED STATES, 1987-1997 (ICPSR 9477)] program sites to determine whether using a more detailed informed consent procedure and/or altering the sequence of the interview and urine specimen collection could enhance the validity of arrestees' self-reports of drug use without adversely affecting study response rates. A 2x2 factorial design was used to assess the effects of the two manipulations. The first two experimental conditions involved administering either the standard DUF informed consent or an enhanced consent that told the arrestees more about the confidential nature of the research and the capabilities of urinalysis. The second two conditions involved collecting the urine specimen either before or after the interview was administered. The experiment included 2,015 adult arrestees from Cleveland, Ohio, Detroit, Michigan, and Houston, Texas, who were randomly assigned to one of the four experimental conditions. The experiment was designed so that the only variability across the interviews was the manipulation of informed consent and the sequencing of the urine specimen request. All other procedures of a standard DUF collection were followed. Data were collected in Cleveland between July 8 and August 22, 1997, in Detroit from August 4 to September 27, 1997, and in Houston from October 17 to November 1, 1997. Variables specific to this project include the experimental condition to which the respondent was assigned, follow-up questions asking whether the arrestee would have responded differently if assigned to the other conditions, and several dummy variables on length and type of drug use. Data from the DUF interview provided detailed information about each arrestee's self-reported use of 15 drugs. For each drug type, arrestees were asked whether they had ever used the drug, the age at which they first used the drug, whether they had used the drug within the past three days, how many days they had used the drug within the past month, whether they had ever needed or felt dependent on the drug, and whether they were dependent on the drug at the time of the interview. Data from the DUF interview instrument also included alcohol/drug treatment history, information about whether arrestees had ever injected drugs, and whether they were influenced by drugs when the crime that they were charged with was committed. The data also include information about whether the arrestee had been to an emergency room for drug-related incidents and whether he or she had had prior arrests in the past 12 months. Urine tests screened for the presence of ten drugs, including marijuana, opiates, cocaine, PCP, methadone, benzodiazepines (Valium), methaqualone, propoxyphene (Darvon), barbiturates, and amphetamines (positive test results for amphetamines were confirmed by gas chromatography). Demographic data include the age, race, sex, educational attainment, marital status, employment status, and living circumstances of each respondent.
