The Cambridge-Somerville Youth Study was the first large-scale randomised experiment in the history of criminology. [1] It was commissioned in 1936 by Dr. Richard Cabot, a Boston physician who proposed an experiment to evaluate the effects of early intervention in preventing or reducing rates of juvenile delinquency. It was started in 1939 by Edwin Powers and Helen Witmer. [2] [3]
For the study, 506 boys, ages 5 to 13 years old who lived in youth facilities in eastern Massachusetts, were selected and matched carefully into either a treatment group or a control group. The boys in the treatment group were assigned a counselor and received academic tutoring, medical and psychiatric attention, and referrals to YMCA, Boy Scouts, summer camps and community programs. Boys in the control group were only told to report regularly. [2] [4] [5]
For the initial and ten year follow up, there was either no difference or a greater rate of negative results as reported by the authors. [2] 30 years after the initial experiment about 95% of the participants were found by using public records and surveyed by Joan McCord. [5] [6]
McCord found that when compared to the control group, men in the treatment group were, to a statistically significant degree
Yet the program had no significant impacts on juvenile arrest rates measured by official or unofficial records. The program also had no impacts on adult arrest rates. There were no significant differences between the two groups in the number of serious crimes committed, age at when a first crime was committed, age when first committing a serious crime, or age after no serious crime was committed. A larger proportion of criminals from the treatment group went on to commit additional crimes than their counterparts in the control group. [5]
In 1981, McCord published a study from new data she gathered about the original participants of the Cambridge-Somerville Youth Study. Compared to the control group of the study, she found that a significantly greater proportion of the treatment group
She formulated four hypotheses about why the program had some damaging results to the treatment group: (1) that counselors imposed middle-class values on lower-class youth which did not help the youth. (2) that boys in the treatment group became dependent on counselors and, when the program ended, the boys lost a source of help. (3) that the treatment group suffered a labeling effect. (4) that the helpfulness of the counselors increased expectations of the boys in the treatment group which could not be sustained, resulting in disillusionment after the program was completed.

Juvenile delinquency, also known as juvenile offending, is the act of participating in unlawful behavior as a minor or individual younger than the statutory age of majority. These acts would otherwise be considered crimes if the individuals committing them were older. The term delinquent usually refers to juvenile delinquency, and is also generalised to refer to a young person who behaves an unacceptable way.
Sex differences in crime are differences between men and women as the perpetrators or victims of crime. Such studies may belong to fields such as criminology, sociobiology, or feminist studies. Despite the difficulty of interpreting them, crime statistics may provide a way to investigate such a relationship from a gender differences perspective. An observable difference in crime rates between men and women might be due to social and cultural factors, crimes going unreported, or to biological factors for example, testosterone or sociobiological theories). The nature or motive of the crime itself may also require consideration as a factor.
In sociology, the social disorganization theory is a theory developed by the Chicago School, related to ecological theories. The theory directly links crime rates to neighbourhood ecological characteristics; a core principle of social disorganization theory that states location matters. In other words, a person's residential location is a substantial factor shaping the likelihood that that person will become involved in illegal activities. The theory suggests that, among determinants of a person's later illegal activity, residential location is as significant as or more significant than the person's individual characteristics. For example, the theory suggests that youths from disadvantaged neighborhoods participate in a subculture which approves of delinquency, and that these youths thus acquire criminality in this social and cultural setting.
The American juvenile justice system is the primary system used to handle minors who are convicted of criminal offenses. The system is composed of a federal and many separate state, territorial, and local jurisdictions, with states and the federal government sharing sovereign police power under the common authority of the United States Constitution. The juvenile justice system intervenes in delinquent behavior through police, court, and correctional involvement, with the goal of rehabilitation. Youth and their guardians can face a variety of consequences including probation, community service, youth court, youth incarceration and alternative schooling. The juvenile justice system, similar to the adult system, operates from a belief that intervening early in delinquent behavior will deter adolescents from engaging in criminal behavior as adults.
Sheldon Glueck was a Polish-American criminologist. He and his wife Eleanor Glueck collaborated extensively on research related to juvenile delinquency and developed the "Social Prediction Tables" model for predicting the likelihood of delinquent behavior in youth. They were the first criminologists to perform studies of chronic juvenile offenders and among the first to examine the effects of psychopathy among the more serious delinquents.
Juvenile delinquency in the United States refers to crimes committed by children or young people, particularly those under the age of eighteen.
The United States incarcerates more of its youth than any other country in the world,, through the juvenile courts and the adult criminal justice system, which reflects the larger trends in incarceration practices in the United States. In 2010, approximately 70,800 juveniles were incarcerated in youth detention facilities alone. As of 2006, approximately 500,000 youth were brought to detention centers in a given year. This data does not reflect juveniles tried as adults. As of 2013, around 40% were incarcerated in privatized, for-profit facilities.

The correlates of crime explore the associations of specific non-criminal factors with specific crimes.
Eleanor Touroff Glueck was an American social worker and criminologist. She and her husband Sheldon Glueck collaborated extensively on research related to juvenile delinquency and developed the "social prediction tables" model for ascertaining the likelihood of delinquent behavior in youth. They were the first criminologists to perform studies of chronic juvenile offenders and among the first to examine the effects of psychopathy among the more serious delinquents.
Criminology is the interdisciplinary study of crime and deviant behaviour. Criminology is a multidisciplinary field in both the behavioural and social sciences, which draws primarily upon the research of sociologists, political scientists, economists, legal sociologists, psychologists, philosophers, psychiatrists, social workers, biologists, social anthropologists, scholars of law and jurisprudence, as well as the processes that define administration of justice and the criminal justice system.
Joan Fish McCord was an American professor of Criminology at Temple University. Through her experimental studies of delinquency, including the Cambridge Somerville Youth Study, and her philosophical perspective, she made important contributions to the understanding of developmental criminology, the differing roles of mothers, fathers, and neighborhoods, and the importance of differentiating between discipline and punishment. McCord was a recipient of the Herbert Bloch Award from the American Society of Criminology. and the International Society of Criminology's Emile Durkheim prize.
Gender responsive approach for girls in the juvenile justice system represents an emerging trend in communities and courts throughout the United States, Australia and Latin America, as an increasing number of girls are entering the juvenile justice system. A gender responsive approach within the juvenile justice system emphasizes considering the unique circumstances and needs of females when designing juvenile justice system structures, policies, and procedures.

Messinger Professor of Criminology, and the executive director of the Center for Criminology and Public Policy Research at the Florida State University College of Criminology and Criminal Justice.
Experimental criminology is a field within criminology that uses scientific experiments to answer questions about crime: its prevention, punishment and harm. These experiments are primarily conducted in real-life settings, rather than in laboratories. From policing to prosecution to probation, prisons and parole, these field experiments compare similar units with different practices for dealing with crime and responses to crime. These units can be individual suspects or offenders, people, places, neighborhoods, times of day, gangs, or even police officers or judges. The experiments often use random assignment to create similar units in both a "treatment" and a "control" group, with the "control" sometimes consisting of the current way of dealing with crime and the "treatment" a new way of doing so. Such experiments, while not perfect, are generally considered to be the best available way to estimate the cause and effect relationship of one variable to another. Other research designs not using random assignment are also considered to be experiments because they entail human manipulation of the causal relationships being tested.
Mendota Juvenile Treatment Center (MJTC) is a juvenile psychiatric facility of the Wisconsin Department of Health Services, located in the Lorenz Hall Annex on the grounds of the Mendota Mental Health Institute (MMHI) in Madison, Wisconsin. It has space for 29 patients. The inmates at Mendota usually have anti-social personality disorders who do not feel empathy, guilt, nor remorse. It uses the Mendota Juvenile Treatment Center Program.
J. David Hawkins is an American sociologist, academic, and author. He is Emeritus Endowed Professor of Prevention and founding director of the Social Development Research Group in the School of Social Work at the University of Washington. His research focuses on the prevention of behavior problems in children and adolescents. He developed the Communities That Care prevention system with Richard F. Catalano.
Community crime prevention relates to interventions designed to bring reform to the social conditions that influence, and encourage, offending in residential communities. Community crime prevention has a focus on both the social and local institutions found within communities which can influence crime rates, specifically juvenile delinquency.
