National Incidence Studies of Missing, Abducted, Runaway, and Thrownaway Children (NISMART), 1988 (ICPSR 9682)

Released/updated on: 1996-11-21
Geographic coverage: United States
This collection was undertaken in response to the mandate of the 1984 Missing Children Act. The objective of the act was to estimate the incidence of five categories of children: children abducted by family members, children abducted by nonfamily members, runaways, thrownaways (those not wanted by their families or taken from families because of abuse or neglect), and children considered missing. Data were collected by several different methods. The centerpiece of this collection is a household survey (Parts 19, 20, and 35) that interviewed families to determine whether any children fit the categories under study. Basic demographic information on age, race, and sex was collected, and questions on the family situation were asked of identified children and their parents and siblings. A survey of juvenile facilities (Parts 28 and 29) was also conducted to determine how many children had run away from these facilities. Facility administrators were prompted for demographic information on the runaways as well as for information on the structure of the runaways' families. In addition, a survey of returned runaways (children who had run away and returned home) (Part 30) was completed to find out whether children's accounts of runaway episodes matched the accounts given by their parents. Children were queried about their relationships with their parents and their views of their contributions to the family. They were also asked about each specific runaway episode: whether they actually ran away or were asked to leave, how long the episode lasted, whether friends knew about it, whether friends accompanied them, whether they used drugs before, during, or after the episode, how they were found, where they were found, and whether disciplinary action was taken. The police records component (Parts 31-33) contains information on homicides, abductions, and sexual assaults.

National Incidence Studies of Missing, Abducted, Runaway, and Thrownaway Children (NISMART), 1999 (ICPSR 4566)

Released/updated on: 2017-12-12
Geographic coverage: United States
Time period: 1997-01-01--1999-01-01
The National Incidence Studies of Missing, Abducted, Runaway, and Thrownaway Children (NISMART) were undertaken in response to the mandate of the 1984 Missing Children's Assistance Act (Pub.L. 98-473) that requires the Office of Juvenile Justice and Delinquency Prevention (OJJDP) to conduct periodic national incidence studies to determine the actual number of children reported missing and the number of missing children who are recovered for a given year. The first such study, NISMART-1 (NATIONAL INCIDENCE STUDIES OF MISSING, ABDUCTED, RUNAWAY, AND THROWNAWAY CHILDREN (NISMART), 1988 [ICPSR 9682]), was conducted from 1988 to 1989 and addressed this mandate by defining major types of missing child episodes and estimating the number of children who experienced missing child episodes of each type in 1988. At that time, the lack of a standardized definition of a "missing child" made it impossible to provide a single estimate of missing children. As a result, one of the primary goals of NISMART-2 was to develop a standardized definition and provide unified estimates of the number of missing children in the United States. Both NISMART-1 and NISMART-2 comprise several component datasets designed to provide a comprehensive picture of the population of children who experienced qualifying episodes, with each component focusing on a different aspect of the missing child population. The Household Survey -- Youth Data and the Household Survey -- Adult Data (Parts 1-2) are similar but separate surveys, one administered to the adult primary caretaker of the children in the sampled household and the other to a randomly selected household youth aged 10 through 18 at the time of interview. The Juvenile Facilities Data on Runaways (Part 3) sought to estimate the number of runaways from juvenile residential facilities in order to supplement the household survey estimate of the number of runaways from households. And the Law Enforcement Study Data, by case perpetrator, and victim, (Parts 4-6) intended to estimate the number of children who were victims of stereotypical kidnappings and to obtain a sample of these cases for in-depth study.

National Incidence Studies of Missing, Abducted, Runaway and Thrownaway Children (NISMART), [United States], 2011 (ICPSR 36566)

Released/updated on: 2017-08-28
Geographic coverage: United States
Time period: 2011-06-01--2012-03-01, 1961-08-01--2011-09-01
The National Incidence Studies of Missing, Abducted, Runaway, and Thrownaway Children (NISMART) were undertaken in response to the mandate of the 1984 Missing Children's Assistance Act (Pub.L. 98-473) that requires the Office of Juvenile Justice and Delinquency Prevention (OJJDP) to conduct periodic national incidence studies to determine the actual number of children reported missing and the number of missing children who are recovered for a given year. The third installment, NISMART-3, was undertaken in 2011 and is comprised of three components; an adult household survey, a survey of juvenile facilities and a survey of law enforcement. It was designed to provide a comprehensive picture of the population dealing with missing children issues and each component focusing on a different aspect of that population namely; the general population, law enforcement and juvenile detention centers across the country. Due to low response rates the data from the youth supplement to the household survey and the juvenile detention center data are unavailable and are not provided here.

National Survey of Children's Exposure to Violence I, 1990-2008 [United States] (ICPSR 35203)

Released/updated on: 2016-09-21
Geographic coverage: United States
Time period: 1990-01-01--2008-07-01

The National Survey of Children's Exposure to Violence (NatSCEV) series involved three rounds of data collection, this study NatSCEV I (baseline), NatSCEV II, and NatSCEV III. For more information on other parts to the series, please use the following links:

NatSCEV III (ICPSR 36523) - http://doi.org/10.3886/ICPSR36523.v1

The National Survey of Children's Exposure to Violence I was designed to obtain lifetime and one-year incidence estimates of a comprehensive range of childhood victimizations across gender, race, and developmental stage. Conducted between January and July, 2008, it assessed the experiences of a nationally representative sample of 4,549 children aged 1 month to 17 years living in the contiguous United States (excluding New Hampshire).

The primary sample of households was selected from a nationwide sampling frame of residential telephone numbers by random digit dialing (RDD). A second sample was drawn by over-sampling United States telephone exchanges that had a population of 70 percent or more of African American, Hispanic, or low-income households.

A short interview was conducted with an adult caregiver (usually a parent) to obtain family demographic information. One child was randomly selected from all eligible children in a household by selecting the child with the most recent birthday. The survey used an enhanced version of the Juvenile Victimization Questionnaire (JVQ), an inventory of childhood victimization. This version of the JVQ obtains reports on 48 forms of offenses against youth that cover five general areas of concern including: conventional crime, child maltreatment, peer and sibling victimization, sexual assault, and witnessing and indirect victimization. Follow-up questions for each victimization item gathered additional information about the victimization incident.

The data set has 1,824 variables and 4,549 cases.

The National Survey of Children's Exposure to Violence II was designed to obtain lifetime and one-year incidence estimates of a comprehensive range of childhood victimizations across gender, race, and developmental stage. Conducted between March, 2011 and January, 2012, it assessed the experiences of a nationally representative sample of 4,503 children aged 1 month to 18 years living in the contiguous United States (excluding New Hampshire).

A nationwide sample which excluded any phone numbers with area codes assigned within the state of New Hampshire was constructed using four frames: (1) 801,317 landline telephone numbers from which telephone households could be drawn by random digit dialing (RDD); (2) 5,000 cell-phone telephone numbers from which a sample of cell phone users could be drawn by RDD; (3) an address-based sample (ABS) of 70,924 cell phone and residential numbers; and (4) a pre-screened sample of 3,573 telephone numbers of households with children from a recent national RDD survey. The compiled frame yielded 3,259 residential RDD interviews, 31 cell phone RDD interviews, 750 ABS interviews, and 463 pre-screened sample interviews for a total of 4,503 interviews.

A short interview was conducted with an adult caregiver (usually a parent) to obtain family demographic information. One child was randomly selected from all eligible children in a household by selecting the child with the most recent birthday. If the selected child was 1 month to 9 years old, the main interview was conducted with the caregiver. If the selected child was 10-17 years old, the main interview was conducted with the child.

The survey used an enhanced version of the Juvenile Victimization Questionnaire (JVQ), an inventory of childhood victimization. This version of the JVQ obtains reports on 53 forms of offenses against youth that cover six general areas of concern including: conventional crime, child maltreatment, peer and sibling victimization, sexual victimization, witnessing and indirect victimization, and internet victimization. Follow-up questions for each victimization item gathered additional information about the victimization incident.

The National Survey of Children's Exposure to Violence III was designed to obtain lifetime and one-year incidence estimates of a comprehensive range of childhood victimizations across gender, race, and developmental stage. Conducted between August 2013 and April 2014, it assessed the experiences of a nationally representative sample of 4,000 children less than 18 years of age living in the contiguous United States (excluding New Hampshire).

A short interview was conducted with an adult caregiver (usually a parent) to obtain family demographic information. One child was randomly selected from all eligible children in a household by selecting the child with the most recent birthday. If the selected child was 1 month to 9 years old, the main interview was conducted with the caregiver. If the selected child was 10-17 years old, the main interview was conducted with the child.

The NatSCEV III questionnaire was very similar to the previous wave minus the extended family exposure to violence follow-up section that was included in NatSCEV II. The questionnaire asked for household demographics and questions about the focal child's health. A series of 52 juvenile victimization screening questions (JVQ) were asked, and for every screener the respondent endorsed, a series of follow-up questions about that victimization was asked. In addition, the survey included sections on lifetime and past year adversity, internet victimization, community disorder, bullying, delinquency, and the child/parent relationship.

Victims of Technology-Facilitated Abuse: Prevalence, Awareness, Dynamics, Help-seeking and Reporting, United States, 2021 (ICPSR 38917)

Released/updated on: 2024-12-10
Geographic coverage: United States

This study was a cross-sectional, national (United States) survey of victims designed to help law enforcement and policymakers to better understand and respond to technology-facilitated abuse (TFA), including non-consensual pornography, sextortion, and cyberstalking. The specific goals for this study were:

  1. Provide information on prevalence, offense dynamics, and levels of awareness about TFA among young adults to help inform policy on this issue.
  2. Develop information on the risk and protective factors associated with TFA victimization to help direct prevention and protection factors.
  3. Improve understanding of what promotes or prevents help-seeking and police reporting of TFA exposure; and obtain baseline data to allow monitoring of help-seeking improvements over time.
  4. Assess costs and consequences of TFA victimization to help inform policy prioritizations and better focus intervention among victims.

This study consisted of four phases. In Phase 1, the research team conceptualized and operationalized TFA domains in consultation with subject matter experts. In Phase 2, cognitive interviews were conducted with students and staff from a large state university (n=13). In phase 3, a pilot survey was distributed and data collected from 111 respondents. Phase 4 was the full-scale administration of the final survey. Respondents were Ipsos KnowledgePanel (KP) panelists aged 18-28 (n=2,639). This collection contains only the data from the full survey.
