Children are the hidden victims of the prison boom. Parental incarceration can cause profound emotional and practical difficulties for them as they strive to cope with separation, financial loss, stigma, and highly restrained contact with their loved ones. This book takes a hard look at possible long-lasting effects of parental incarceration on children in the United States, England, Sweden and the Netherlands. Four major studies of some 20,000 children, followed from childhood to adulthood, demonstrate the far-reaching consequences that parental incarceration can have for children in later years. The worst effects occur in social contexts characterized by harsh penal attitudes and restrictive prison practices. These cross-national differences illustrate the need for reforms to better protect this vulnerable population.

This Brief fills a gap in criminological literature, as there are few empirically-based studies on delinquency of adolescent girls. It provides results of a longitudinal study, The Pittsburgh Girls Study (PGS), which includes 2,451 girls, followed annually from age 10-19, the ages when criminal behavior tends to emerge. This study provides the most extensive and comprehensive investigation into the criminal offending and self-reported trajectories of offending of PGS participants, along with an in-depth examination of other criminal career dimensions.In five chapters, this short volume reviews the limited extent of girls' delinquency literature, presents data on girls' offending patterns (onset, persistence, specialization, and desistence), provides insights on gender differences by comparison with the Pittsburgh Youth Study, which focused on male offenders, and explores the theoretical and practical implications of the results.By understanding the origins and onset of criminal behavior in girls, researchers can begin to understand effective interventions and crime prevention. This Brief will be of interest to researchers in criminology and criminal justice, as well as related fields such as sociology, public policy, and psychology.

This Brief examines criminal careers by providing the most extensive and comprehensive investigation to date on the official offending, self-reported offending, and trajectories of offending of the Pittsburgh Youth Study (PYS) participants. The PYS is a longitudinal study, which was initiated in 1987, and involves repeated follow-ups on several community cohorts (starting in grades 1, 4, and 7) of inner-city boys in Pittsburgh, Pennsylvania. This Brief covers the Youngest and Oldest PYS cohorts (which had the most follow-up and most data available) from ages 10-30. It provides the most complete descriptive analyses of the criminal careers of these males to date. The three cohorts are commonly referred to as the Youngest, Middle, and Oldest cohorts, respectively. Consistent with several prior publications with the PYS data (Loeber et al., 2008), this book focuses only on data from the Youngest and Oldest cohorts as these cohorts were followedup the most frequently and have the longest time window of data available. It will be of interest to researchers in Criminology and Criminal Justice, as well as related fields like Sociology, Developmental Psychology, Social Policy, and Education.

Epidemiological surveys have provided key information about the prevalence and degree of seriousness at different ages of a wide array of problem behaviors such as delinquency, substance use, early sexual involvement, and mental health disorders. Knowledge of the extent of these problems and changes in their course over time is important. In its absence, interventions and health planning in general can be difficult. Understanding which risk and protective factors are relevant to which problem behaviors is also essential for the formulation of theories that constitute the basis of intervention. This book draws on the results of the major Pittsburgh Youth Study complemented by follow-up tracking of juvenile court records for more than six years, to address the following questions: *What is the prevalence and age of onset of delinquency, substance use, and early sexual behavior for three samples of boys age 8, 11, and 14? What are the average mental health problems for these ages? How strong are the relationships among these problem behaviors in each of the samples? *Which variables best explain individual differences among the boys in their manifestations of delinquency, substance use, early sexual behavior, and mental health problems? To what extent do explanatory factors vary with age? How accurately can boys with different outcomes be identified by risk scores based on hierarchical multiple regressions? *To what extent are explanatory factors associated with one outcome that are also associated with other outcomes? Are explanatory factors that are especially characteristic of a multiproblem group of boys--who display many different problem behaviors--different from explanatory factors associated with boys with few problems? *Do the results fit a general theory of juvenile problem behaviors, or is a differentiated theory more applicable?

The first decade of the new century proved to be a deadly one for many children and young people in the United States. Despite increased policing on the streets, higher rates of incarceration, harsher sentencing, stricter control of illegal drugs, and attempts to reduce access to firearms, FBI reports show that more than 7,300 young people between the ages of 15 and 29 were murdered in 2008 alone. It’s clear that traditional crime reduction strategies have not stemmed the rising tide of homicides perpetrated by and upon one of society’s most vulnerable populations. Innovative, practicable solutions are needed to staunch this lethal trend.Based on the findings of a unique longitudinal study, Young Homicide Offenders and Victims: Risk Factors, Prediction, and Prevention from Childhood now provides experts with unprecedented analysis of prospectively collected data on 1,517 boys and young men who grew up in Pittsburgh, Pennsylvania. Following these males from childhood into early adulthood, examining their lives and the conditions under which they grew up in a representative mid-sized American city, the study forms the basis of this unique volume designed to stimulate debate on key questions of prevention and intervention as well as dispel popular myths about the childhood and adolescent features of homicide offenders and homicide victims. Key areas of coverage include:Early childhood risk factors of young homicide offenders and victims. Insights into homicide offenders’ lives as told in their own words.The effectiveness of screening for at-risk youth. Risk factor–based prevention and intervention strategies.The impact of interventions on homicide rates.Policy implications at the local, state, and national levels.Young Homicide Offenders and Victims: Risk Factors, Prediction, and Prevention from Childhood is essential reading for researchers,practitioners, and policy makers across the fields of juvenile justice and criminology, developmental psychology, sociology, psychiatry, public health, and policy making.-------“This book changes the game in violence research … The analysis is masterful, the prose is readable, and the achievement is nothing short of stunning.”Richard Rosenfeld, Ph.D. / Curators Professor of Criminology and Criminal Justice, University of Missouri-St. Louis“This book will stand the test of time as a landmark homicide study.”James C. Howell, Ph.D. / Senior Research Associate, National Gang Center“This is a fascinating, pioneering book … The authors’ sophisticated analyses demonstrate convincingly the considerable value of prospective longitudinal data for enhancing our understanding of the etiology and control of lethal violence.”Steven F. Messner, Ph.D. / Distinguished Teacher Professor, Department of Sociology, University at Albany, SUNY / President, American Society of Criminology

Between 1980 and 1996 the number of arrests has increased considerably for offenders ages 12 and under. This increase is a cost to society in two ways: the cost of the crime and the cost of multiple agencies involved with these children. Several questions have developed due to this increase: How does the juvenile justice system deal with child delinquents? Is child delinquency a predictor of serious, violent, and chronic offending? How early can we predict delinquency, and what are early warning signs? In an effort to develop answers for these questions and many more, editors Rolf Loeber and David Farrington organized a study group on Very Young offenders comprising 39 experts on juvenile delinquency and child problem behavior. Over a two-year period of intense and collaborative work these individuals have produced the book Child Delinquents: Development, Intervention, and Service Needs. Presenting empirically derived insights, Child Delinquents is the definitive statement to date on the working knowledge of prevalence, development, risk and protective factors, and optimal intervention with preteen offenders. This book is an excellent source for a broad audience of researchers, scholars, psychiatry, and practitioners at the administrative level.
