Addressing Under-reporting of Minor Victim Sex Trafficking, Florida, 2011-2017 (ICPSR 37169)
African American Experience of Sexual Assault in Maryland, 2003-2006 (ICPSR 25201)
The purpose of this study was to better understand the problem of sexual assault among African American women in Maryland, assess their use of available resources in response to sexual assault, and explore their use of alternative sources of care. Researchers interviewed 223 female victims of sexual assault (Part 1 and Part 2) between January 2004 and July 2005 and conducted 21 focus groups (Part 3) with sexual assault resource service providers between 2003 and 2006. Criteria for inclusion in the interview component (Part 1 and Part 2) of the study included: African American or Caucasian female, aged 18 and over, resident of Maryland, and victim of sexual assault. There were four streams of recruitment for the interview portion of the study:
- Victims receiving services at one of 18 rape crisis centers located throughout the state of Maryland;
- Community outreach sessions conducted by rape crisis center community educators;
- Through community service providers, including those working in domestic violence centers, forensic nurse examiners (SAFE programs), probation and parole offices, reproductive health centers, county health departments, community services agencies, Historically Black Colleges and Universities, and local colleges; and
- Through three detention centers housing female inmates.
For Part 3 (Focus Group Qualitative Data), rape crisis center representatives and other community service provider representatives received a letter informing them that a focus group was going to be conducted at the end of their study training session and asked them for their participation. Part 1 (Victim Quantitative Data) includes items in the following categories: Personal Demographics, Details of the Sexual Assault, Medical Care, Law Enforcement, Prosecution/Court Process, Sexual Assault Center Services, Other Counseling Services, and Recommendations for Improvement. Part 2 (Victim Qualitative Data) includes responses to selected questions from Part 1. The data are organized by question, not by respondent. Part 3 (Focus Group Qualitative Data) includes questions on the needs of African American women who have been sexually assaulted, whether their needs are different from those of women of other racial/ethnic backgrounds, unique barriers to reporting sexual assault to police for African American women and their treatment by the criminal justice system, unique issues concerning the use of available resources by African American women, such as post-rape medical care and counseling services, and recommendations on how the state of Maryland could improve services for African American women who are the victims of sexual assault.

This study tested a model of individual, familial, and peer variables that additively and synergistically increased or decreased the risk for sexual and teen dating violence based on bullying experiences in early adolescence. The study surveyed 1,162 students from three cohorts in four Midwestern middle schools, who were then followed into three high schools. Five waves of surveys collected information about the level of violence in student homes with parents and siblings or with other children, physical abuse, sexual abuse, exposure to domestic violence, frequency of bullying, self-reported delinquency, and exposure to delinquent friends during the middle school years. Waves six and seven were collected during high school and sexual violence and teen dating violence measures were added to the surveys.

This study was designed to examine how districts that experienced an incident of school employee sexual misconduct in 2014 defined, interpreted, and implemented key elements of Title IX before, during, and after an incident. The study used a qualitative case study design with a purposeful sample of five districts recruited from a database of 459 districts who experienced a case of school employee sexual misconduct in 2014. The study was conducted between January 2016 and September 2017.
Data collected included: 1) various district documents, 2) 41 interviews with primary actors (school employees and county officials directly involved in responding to the incident), 3) 10 focus groups with 51 secondary actors (school employees who were not directly involved with the incident but who might have been indirectly affected by it), and 4) offender, victim and district characteristics. Documents reviewed included written policies and protocols, training materials and handbooks for staff and students, case documents, and other guiding documents as applicable. In interviews and focus groups, participants were asked to discuss their knowledge of district policies and procedures, to describe the dissemination of and any changes to these policies and procedures, and to provide recommendations for improvement. To protect the confidentiality all district and participant identifying information is confidential and has been removed from any reporting.

The four primary goals of The Detroit Sexual Assault Kit Action Research Project (DSAK-ARP) were:
- To assess the scope of the problem by conducting a complete census of all sexual assault kits (SAKs) in police property.
- To identify the underlying factors that contributed to why Detroit had so many un-submitted SAKs.
- To develop a plan for testing SAKs and to evaluate the efficacy of that plan.
- To create a victim notification protocol and evaluate the efficacy of that protocol.
To conduct the census and investigate factors that contributed to untested SAKs, The study investigated police and other public records, interviewed public officials and employees and manually cataloged untested SAKs to conduct the census and gather information as to the decision making processes as to why the SAKs remained untested.
A random sample of 1,595 SAKs were tested as part of developing a SAK testing plan. Kits were divided into four testing groups to examine the utility of testing SAKs for stranger perpetrated sexual assaults, non-stranger perpetrated sexual assaults and sexual assaults believed to be beyond the statute of limitations. The final testing group split SAKs randomly into two addition sample sets as part of an experimental design to examine whether the testing method of selective degradation was a quicker and more cost efficient approach that offered satisfactory levels of accuracy when compared to standard DNA testing methods.
A two stage protocol was created to inform sexual assault victims that their SAKs had been tested, discuss options for participating with the investigation and prosecution process and connect the victim with community services.

This study measures the size and structure of the underground commercial sex economy in eight major US cities: San Diego, Seattle, Dallas, Denver, Washington, DC, Kansas City, Atlanta, and Miami. The goals of this study were to derive a more rigorous estimate of the underground commercial sex economy (UCSE) in eight major US cities and to provide an understanding of the structure of this underground economy.
Researchers relied on a multi-method approach using both qualitative and quantitative data to estimate the size of UCSE including:
- Collecting official data on crime related to the underground weapons and drugs economies
- Conducting semi-structured interviews with convicted traffickers, pimps, child pornographers, and sex workers at the federal, state, and local levels
- Conducting semi-structured interviews with local and federal police investigators and prosecutors to inform our analysis of the interrelationship across different types of underground commercial sex activity.
Evaluation of the Implementation of the Sex Offender Treatment Intervention and Progress Scale (SOTIPS), United States, 1978-2017 (ICPSR 37035)
The purpose of the project was to (1) determine whether the combined dynamic (SOTIPS) and static risk assessment (Static-99R) tools better predicted sexual recidivism than either alone, and (2) determine whether the tools could be implemented successfully in more representative populations. Previous research has established a "status quo" for risk assessments.
This study was set within the context of the developing sexual offender risk prediction field, where investigators explored reliable and valid means to assess what have been termed "dynamic risk factors." Instruments that identify the specific psychological risk factors present in the individual offender ought to allow treatment for that individual to be tailored to these specific needs, thus increasing its effectiveness. Thus, instruments have been designed to:
- Assess psychological factors that are empirically related to sexual recidivism, thus creating a basis for selecting treatment targets
- Show robust incremental predictive validity relative to Static-99R or other measures of static risk factors
- Measure change in a way that is convincingly related to sexual recidivism
- Incorporate and point risk managers towards some of the factors identified in the desistance literature
- Improve the effectiveness of treatment in reducing sexual recidivism
Enrollment of sex offenders in the evaluation study began in April 2013. To be included, offenders needed to be Static-99R eligible (an adult male convicted of a contact or non-contact sex offense with an identifiable victim), mentally cognizant, released to community supervision, and at least 18 years old in January 2013 in Maricopa County and April 2013 in New York City.
Federally Prosecuted Commercial Sexual Exploitation of Children (CSEC) Cases, United States, 1998-2005 (ICPSR 26722)
To increase understanding of the prosecution of Commercial Sexual Exploitation of Children and Youth (CSEC) offenders, the Urban Institute, a non-partisan social and economic policy research organization, along with Polaris Project, an anti-human trafficking organization based in the United States and Japan, were awarded a cooperative agreement from the Office of Juvenile Justice and Delinquency Prevention (OJJDP) to conduct a 12-month study on CSEC in the United States. The purpose of this research was to conduct a national analysis of federal prosecutions of CSEC-related cases from 1998 through 2005, in order to answer the following four research questions:
- Is the United States enforcing existing federal laws related to CSEC?
- What are key features of successfully prosecuted CSEC cases? What factors predict convictions in cases? What factors predict sentence length?
- Have the U.S. courts increased penalties associated with sexual crimes against children?
- What, if any, are the effects of CSEC legislation on service providers who work with these victims?
The data collection includes three datasets: (Dataset 1) Base Cohort File with 7,696 cases for 50 variables, (Dataset 2) Commercial Sexual Exploitation of Children (CSEC) Defendants in cases filed in U.S. Court with 7,696 cases for 100 variables, and (Dataset 3) Suspects in Criminal Matters Investigated and Concluded by U.S. Attorneys Dataset with 13,819 cases for 14 variables.
Identify, Respond, Prevent: Addressing Human Trafficking Among Youth Involved in Juvenile Justice and Child Welfare Systems, Florida, 1993-2020 (ICPSR 39039)
This study extended the understanding of human trafficking among youth involved in child welfare and juvenile justice systems by examining relationships among trafficking victimization, youth characteristics, and experiences in the juvenile justice, child welfare, and criminal justice systems. Using de-identified linked administrative data provided by the Florida Department of Juvenile Justice (DJJ), Florida Department of Law Enforcement (FDLE), and the Florida Department of Children and Families (DCF), researchers:
- informed identification of trafficking victimization by assessing the predictive utility of Florida's Human Trafficking Screening Tool, using ordered multinomial regressions and factor analysis;
- informed response to trafficked youth by describing characteristics of those who experience trafficking during juvenile justice or child welfare supervision, or who enter juvenile justice supervision with prior human trafficking allegations, using descriptive statistics and linear and logistic regression;
- informed secondary prevention for at-risk youth by identifying those at greatest risk of human trafficking throughout adolescence, and informed tertiary prevention among trafficked youth by identifying those at greatest risk of subsequent victimization following an initial trafficking allegation;
- investigated the longitudinal association between human trafficking allegations and subsequent juvenile and adult criminal charges. Data collection included all youth served by DCF who were born in or after 1993, and whose records included at least one maltreatment allegation before February 29th, 2020.

This study represents the first comprehensive national assessment of law enforcement uses of and perspectives on sex offender registration and notification (SORN) systems. The two-year, mixed-method study featured collection and analysis of interview data from over two-dozen jurisdictions, and administration of a nationwide survey of law enforcement professionals. The study examined ways in which law enforcement leaders, uniformed staff, and civilian staff engaged in SORN-related duties perceive SORN's roles and functions, general effectiveness, and informational utility. Additionally, the study elicited law enforcement perspectives related to promising SORN and related sex offender management practices, perceived barriers and challenges to effectiveness, and policy reform priorities.
This collection includes two SPSS data files and one SPSS syntax file: "LE Qualitative Data.sav" with 55 variables and 101 cases, "LE Quantitative Data-ICPSR.sav" with 201 variables and 1402 cases and "LE Quantitative Data Syntax.sps".
Qualitative data from interviews conducted with law enorcement professionals are not available at this time.

National Crime Victimization Survey, Concatenated File, 1992-2013 (ICPSR 35165)
The National Crime Victimization Survey (NCVS) Series, previously called the National Crime Surveys (NCS), has been collecting data on personal and household victimization through an ongoing survey of a nationally-representative sample of residential addresses since 1973. The NCVS was designed with four primary objectives: (1) to develop detailed information about the victims and consequences of crime, (2) to estimate the number and types of crimes not reported to the police, (3) to provide uniform measures of selected types of crimes, and (4) to permit comparisons over time and types of areas. The survey categorizes crimes as "personal" or "property." Personal crimes include rape and sexual attack, robbery, aggravated and simple assault, and purse-snatching/pocket-picking, while property crimes include burglary, theft, motor vehicle theft, and vandalism. Each respondent is asked a series of screen questions designed to determine whether she or he was victimized during the six-month period preceding the first day of the month of the interview. A "household respondent" is also asked to report on crimes against the household as a whole (e.g., burglary, motor vehicle theft). The data include type of crime, month, time, and location of the crime, relationship between victim and offender, characteristics of the offender, self-protective actions taken by the victim during the incident and results of those actions, consequences of the victimization, type of property lost, whether the crime was reported to police and reasons for reporting or not reporting, and offender use of weapons, drugs, and alcohol. Basic demographic information such as age, race, gender, and income is also collected, to enable analysis of crime by various subpopulations.
This dataset represents the concatenated version of the NCVS on a collection year basis for 1992-2013. A collection year contains records from interviews conducted in the 12 months of the given year. Under the collection year format, victimizations are counted in the year the interview is conducted, regardless of the year when the crime incident occurred.

A collection year contains records from interviews conducted in the 12 months of the given year. Under the collection year format, victimizations are counted in the year the interview is conducted, regardless of the year when the crime incident occurred.
The 2016 National Crime Victimization Survey (NCVS) violent and property crime estimates were significantly higher than 2015, but it was not possible to determine the degree to which the change in rates resulted from the sample redesign rather than real changes in U.S. victimization levels. Therefore, the Bureau of Justice Statistics (BJS) examined the 2015 and 2016 victimization rates separately for new and continuing sample counties in the 2016 Criminal Victimization bulletin.
The BJS requested that the U.S. Census Bureau create a 2016 revised file with outgoing county interviews from July-December 2015, continuing county interviews from January-June 2016, and all interviews (continuing and new counties) from July-December 2016. In other words, the outgoing 2015 cases replaced the new 2016 cases in the first half of 2016. The files in this study serve as a separate research file to allow data users to make comparisons between 2015, 2016, and 2017 NCVS estimates using a nationally representative sample. It provides a sample that still represents the entire country but does not have the inflated crime rates seen in the new counties in 2016.

Personal crimes include rape and sexual assault, robbery, aggravated and simple assault, and purse-snatching/pocket-picking, while property crimes include burglary, theft, motor vehicle theft, and vandalism. Each respondent is asked a series of screen questions designed to determine whether she or he was victimized during the six-month period preceding the first day of the month of the interview. A "household respondent" is also asked to report on crimes against the household as a whole (e.g., burglary, motor vehicle theft). The data include type of crime, month, time, and location of the crime, relationship between victim and offender, characteristics of the offender, self-protective actions taken by the victim during the incident and results of those actions, consequences of the victimization, type of property lost, whether the crime was reported to police and reasons for reporting or not reporting, and offender use of weapons, drugs, and alcohol. Basic demographic information such as age, race, gender, and income is also collected, to enable analysis of crime by various subpopulations.
This dataset represents the concatenated version of the NCVS on a collection year basis for 1992-2017. A collection year contains records from interviews conducted in the 12 months of the given year. Under the collection year format, victimizations are counted in the year the interview is conducted, regardless of the year when the crime incident occurred.

The 2016 National Crime Victimization Survey (NCVS) violent and property crime estimates were significantly higher than 2015, but it was not possible to determine the degree to which the change in rates resulted from the sample redesign rather than real changes in U.S. victimization levels. Therefore, the Bureau of Justice Statistics (BJS) examined the 2015 and 2016 victimization rates separately for new and continuing sample counties in the 2016 Criminal Victimization bulletin.
The BJS requested that the Census Bureau create a 2016 revised file with outgoing county interviews from July-December 2015, continuing county interviews from January-June 2016, and all interviews (continuing and new counties) from July-December 2016. In other words, the outgoing 2015 cases replaced the new 2016 cases in the first half of 2016. The files in this study serve as a separate research file to allow data users to make comparisons between 2015, 2016, and 2017 NCVS estimates using a nationally representative sample. It provides a sample that still represents the entire country but does not have the inflated crime rates seen in the new counties in 2016.

National Former Prisoner Survey, 2008 (ICPSR 31441)
Under the Prison Rape Elimination Act of 2003, Congress mandated that the United States Department of Justice, Bureau of Justice Statistics (BJS) investigate former prisoners' experiences in prison to assist in understanding the incidence and prevalence of sexual victimization within the prison setting. BJS and its subcontractor, NORC at the University of Chicago, led a national data collection effort focusing on prison sexual assault as reported by former state prisoners.
The focus of the National Former Prisoner Survey (NFPS) was sexual victimization among former state prisoners. The survey was divided into 6 sections. The first two sections were administered using a computer-assisted personal interviewing (CAPI) method and focused on demographic and criminal history information. The remaining sections, covering more sensitive information, were administered using a touch-screen-audio-assisted-computer-self-interviewing (TACASI) method.
Sections A and B of the instrument collected demographic and criminal history information, as well as information on placements during the last continuous incarceration. Sections C and D captured detailed inmate-on-inmate sexual victimization during the last continuous incarceration, including the type of sexual activity, identification of facilities at which such incidents occurred, frequency of occurrences, and other specifics regarding sexual victimization. Section E addressed staff-on-inmate sexual victimization and misconduct, whether considered willing or unwilling, and gathered specifics of activity indicated. The last section, F, focused on the impacts of sexual assault on victimized respondents, as well as parole supervision characteristics for all respondents.
The National Former Prisoner Survey (NFPS) began in January 2008 and concluded in October 2008, and involved the random selection of approximately 250 parole offices across the country using probability proportional-to-size (PPS) sampling procedures. Completed interviews were obtained for 17,738 respondents; supplemental data was collected on all former prisoners sampled in order to develop weights for national estimations.
