This is the Final Summary Overview of the methodology and findings of a study with the goal of finding, collecting, and synthesizing all available published and unpublished research reports that quantitatively analyze the longitudinal relationship between a measure of school violence and later mental health, school performance, or crime/delinquency outcomes. The study used state-of-the-art systematic review and meta-analysis methods to assess the variation in the relationships across studies through multiple-meta-regression modeling. These methods included combining effect sizes by estimating a random effects model with robust variance estimation. A total of 131 research reports from 114 independent studies were included in this meta-analysis. The findings indicate that experiences of various types of school violence are related to adverse outcomes in mental health, school performance, and crime/delinquency. This study distinguished the effects that stem from perpetrating school violence from those attributed to being a victim of school violence. The perpetration of school violence was strongly linked to numerous mental health issues, poor academic performance, and involvement in criminal/delinquent behaviors; on the other hand, being a victim of school violence was associated with only adverse mental health outcomes. Thus, strategies to prevent school violence should view student perpetrators of school violence as having mental health needs, being disconnected from school, and being resistant to school policies. Victims of school violence should be viewed as at risk for mental health disorders, including suicidal ideation.

This study examined factors influencing decisions that lead from a school-based incident to exclusionary discipline, an arrest, and a referral to the juvenile court. Phase 1 involved interviewing groups of key stakeholders including school administrators, district administrators, discipline coordinators, juvenile court judges and other staff, law enforcement officers, Positive Behavior Intervention Support coordinators, and child welfare agencies to understand their approaches to behavior management. For each set of interviews, researchers used the information from the structured interviews to create diagrams outlining the sequence of potential decisions involved in responding to behavior incidents. This report presents the qualitative analysis resulting from Phase 1.

This is the Final Summary Overview of the methodology and findings of a meta-analysis of empirical literature on school violence to determine the key individual-, school-, and community-level factors that influence violence and related problems (victimization, offending, and aggressive behavior) within primary and secondary (K-12) schools. This study's analyses are based on 8,551 effect sizes identified from 693 studies of school violence. The authors note that this is the largest meta-analysis on this issue conducted in the field of criminal justice and is among the largest compiled in the social sciences. A total of 31 predictors of school violence were assessed at the individual, institutional, and community levels. Separate analyses were conducted in assessing the major predictors of any victimization at school, bullying victimization, violent victimization, any aggressive/delinquent behavior at school, bullying perpetration, violent offending, and bringing a weapon to school. The research reviewed indicates that the strongest and most consistent risk factors for various forms of aggression/delinquency at school are antisocial behaviors, deviant peers, victimization, peer rejection, and antisocial attitudes. The strongest predictors for victimization at school are prior victimization, low social competence, peer rejection, violent school context, and negative school climate. LGBT students and those with disabilities are at higher risk for victimization at school. School target-hardening practices, such as security cameras, metal detectors, and school resource officers or security personnel were not found to have any association with any type of violence or victimization at school. 18 tables, 37 references, and a listing of the studies reviewed.

In I978,The National council on Crime and Delinquency (NCCD) published a study entitledWhy Punish the Children? The study JL offered a comprehensive and critical view of the nation's treatment of children whose mothers were incarcerated in the nation's jails and prisons. It documented a neglected and forgotten class of young people whose lives were disrupted and often damaged by the experience of isolation from their imprisoned mothers. Recommendations presented in the study were intended to focus attention on these children and their needs. The present work is a reassessment of the study published in I978. The need for a current appraisal is sharpened by the fact that the incarceration rate for female offenders has skyrocketed in recent years. This has spurred unwelcome growth of the invisible class of infants, children and teenagers who find themselves without a mother at home. While new legions of children are growing up separated from their mothers, government agencies appear more powerless than ever to attend to the needs of the children, their mothers and their caregivers. Now more than ever, we must renew our concern and define our commitment to these children. This report offers an appraisal of their needs and a current agenda for reform.

While gangs and gang culture have been around for countless centuries, The Gang is one of the first academic studies of the phenomenon. Originally published in 1927, Frederic Milton Thrasher’s magnum opus offers a profound and careful analysis of hundreds of gangs in Chicago in the early part of the twentieth century. With rich prose and an eye for detail, Thrasher looked specifically at the way in which urban geography shaped gangs, and posited the thesis that neighborhoods in flux were more likely to produce gangs. Moreover, he traced gang culture back to feudal and medieval power systems and linked tribal ethos in other societies to codes of honor and glory found in American gangs

As a steady source of juvenile delinquents and an incubator for future adult offenders, the youth gang has long been a focus of attention, from their origins and prevalence to intervention and prevention strategies. But while delinquent youth form gangs worldwide, youth gang research has generally focused on the U.S.

Youth Gangs in International Perspective provides a needed corrective by offering significant studies from across Europe, as well as Trinidad-Tobago and Israel. The book spans the diversity of the field in the cultural and scholarly traditions represented and methods used, analyzing not only the social processes under which gangs operate and cohere, but also the evolution of the research base, starting with the Eurogang Program’s definition of the term youth gang. Cross-national and gender issues are discussed, as are measurement concerns and the possibility that the American conception of the youth gang is impeding European understanding of these groups.

Every day there are new stories of gang-related crime: from the proliferation of illegal weapons in the streets and children dealing drugs in their schools, to innocent bystanders caught in the crossfire of never-ending gang wars. Once considered an urban phenomenon, gang violence is permeating American life, spreading to the suburbs and bringing the problem closer to home for much of America. The government, schools, social agencies, and the justice system are conspicuous by their sporadic interest in the subject and have failed to develop effective policies and programs. Existing social support mechanisms and strategies for suppressing violence have often been unsuccessful. And, state and federal policy is largely nonexistent.In The Youth Gang Problem: A Community Approach, Irving Spergel provides a systematic analysis of youth gangs in the United States. Based on research, historical and comparative analysis, and agency documents and the author's extensive first-hand experience, the work explores the gang problem from the perspective of community disorganization, especially population movement, and the plight of the underclass. It examines the factors of gang member personality, gang dynamics, criminal organization, and the influence of family, school, prisons, and politics, as well as the response of criminal justice agencies and community groups.

  Spergel describes techniques used by social agencies, schools, employment programs, criminal justice agencies, and grass-roots organizations for dealing with gangs, and recommends strategies that emphasize the use of local resources, planning, and collaborative procedures.There is no single strategy and no easy solution to the youth gang problem in the United States. There are, however, substantial steps we can take, and they must be honestly and systematically tested. Offering a practical and alternative approach to a serious social problem, The Youth Gang Problem: A Community Approach is a major and long-awaited contribution to this dilemma. It is required reading for criminal justice personnel, school staff, social workers, policy makers, students and scholars of urban and organizational sociology, and the general reader concerned with the youth gang problem and how to control, intervene, and prevent it.

Choo explores group delinquency in the Asian American community. His primary focus is two youth groups, a Korean affiliated Chinese youth gang and a Korean delinquent group. The two groups have evolved through different processes and under different community circumstances. Both manifest differing patterns of delinquent activities and require different approaches to their problems. By analyzing the demographic, socioeconomic, and cultural characteristics of the Korean immigrant community, the book discusses the unique lifestyle of Korean-American immigrants in relation to their youth and group delinquency problem. Choo also explains the phenomenon of gangs and immigrant youth by detailed comparison of the emergence, development, persistence and change of theser two distinctive groups.

Diverting youth from juvenile court involvement should be a central focus in efforts to reduce racial and ethnic disparities and improve outcomes in our nation’s youth justice systems. Clear evidence shows that getting arrested in adolescence or having a delinquency case filed in juvenile court damages young people’s futures and increases their subsequent involvement in the justice system. Compared with youth who are diverted, youth who are arrested and formally petitioned in court have far higher likelihood of subsequent arrests and school failure. Pre-arrest and pre-court diversion can avert these bad outcomes. Research shows that Black youth are far more likely to be arrested than their white peers and far less likely to be diverted from court following arrest. Other youth of color – including Latinx youth, Tribal youth, and Asian/Pacific Islander youth – are also less likely than their white peers to be diverted. The lack of diversion opportunities for youth of color is pivotal, because greater likelihood of formal processing in court means that youth of color accumulate longer court histories, leading to harsher consequences for any subsequent arrest. Expanding diversion opportunities for youth of color therefore represents a crucial, untapped opportunity to address continuing disproportionality in juvenile justice.

In 2017, Los Angeles County established an Office of Youth Diversion and Development to advance a collaboratively designed pre-booking diversion initiative that prevents youth from getting formally arrested or referred to probation during encounters with law enforcement. Human Impact Partners and the Los Angeles (LA) County Office of Youth Diversion and Development (YDD) partnered to develop this evaluation framework to assess and prevent racial inequities in this program. LA County’s pre-booking diversion program is part of a broader effort to reduce mass incarceration of Black and Brown youth . In LA County and across the US, Black and Brown youth are arrested and detained by law enforcement at disproportionately greater rates compared to White youth. Organizing by local youth advocates and policy changes at the local, state, and national level have created opportunities for community-based pre-booking diversion in LA County to reduce the excessive and unfair criminalization and incarceration of Black and Brown youth and equitably improve outcomes for youth.

The United States incarcerates an alarming number of children and adolescents every year. Disproportionately, they are youth of color. Given the short- and long-term damages stemming from youth out of home placement, it is vital to understand its true scope. In 2019, there were more than 240,000 instances of a young person detained, committed, or both in the juvenile justice system.1 However, youth incarceration is typically measured via a one-day count taken in late October.2 This metric vastly understates its footprint: at least 80% of incarcerated youth are excluded from the one-day count. This undercount is most prevalent for detained youth, all of whom have been arrested but have yet to face a court hearing.

Street outreach workers comb public places such as parks, vacant lots, and abandoned waterfronts to search for young people who are living out in public spaces, if not always in the public eye. Street Kids opens a window to the largely hidden world of street youth, drawing on their detailed and compelling narratives to give new insight into the experiences of youth homelessness and youth outreach. Kristina Gibson argues that the enforcement of quality of life ordinances in New York City has spurred hyper-mobility amongst the city’s street youth population and has serious implications for social work with homeless youth. Youth in motion have become socially invisible and marginalized from public spaces where social workers traditionally contact them, jeopardizing their access to the already limited opportunities to escape street life. The culmination of a multi-year ethnographic investigation into the lives of street outreach workers and ‘their kids’ on the streets of New York City, Street Kids illustrates the critical role that public space regulations and policing play in shaping the experience of youth homelessness and the effectiveness of street outreach.

Over the past three decades, States have enacted legislation making it easier to transfer youth to the adult criminal justice system. Although the process occurs with male and female youth, this document specifically addresses the challenges of transferring girls to adult court and correctional systems. Mechanisms developed to move youth into adult systems include Judicial Waiver/Transfer Laws, Prosecutorial Direct Filing, Statutory Exclusion Provisions, the “Once an Adult, Always an Adult” Provisions and Age of Jurisdiction Laws. When making those transfer decisions, less consideration may be given to the idea that adult jails and prisons are not designed for the confinement of youth, and as a result most are not equipped to meet the inherent and specific needs of adolescents.

While not intended as a research document, this bulletin highlights challenges when transferring juveniles to the adult criminal justice system for administrators and the individual justice involved girls. It is hoped that the audience for this document will extend beyond that of adult and juvenile correctional administrators and reach other related stakeholders who are involved in the decision-making regarding the transfer of juveniles to the adult criminal justice system

A growing body of research demonstrates that for many juvenile offenders, lengthy out-of-home placements in secure corrections or other residential facilities fail to produce better outcomes than alternative sanctions. In certain instances, they can be counterproductive. Seeking to reduce recidivism and achieve better returns on their juvenile justice spending, several states have recently enacted laws that limit which youth can be committed to these facilities and moderates the length of time they can spend there. These changes prioritize the use of costly facilities and intensive programming for serious offenders who present a higher risk of reoffending, while supporting effective community-based programs for others.

This report presents information on nine States that have adopted policies within their juvenile justice systems aimed at reducing the incarceration rate of youth in the United States. The nine States singled out for their efforts include California, Connecticut, Illinois, Ohio, Mississippi, New York, Texas, Washington, and Wisconsin. Using data collected by Federal agencies, this report presents details on national and State incarceration trends, with specific focus on the nine States. The analysis found that the decrease in youth incarceration rates is associated with changes in State policies since 2001 that have focused on increasing the availability of evidence-based alternatives to incarceration; requiring intake procedures that reduce use of secure detention facilities; closing or downsizing youth confinement facilities; reducing schools' overreliance on the justice system to address discipline issues; disallowing incarceration for minor offenses; and restructuring juvenile justice responsibilities and finances among States and counties. The nine States identified in this report were selected as a result of adopting at least four of the six policy changes, exceeding the national-average reduction in youth confinement for the period 2001-2010, and experiencing a decline in youth arrests for the same period.
