William Healy’s The Individual Delinquent, first published in 1915, is a landmark in the development of modern criminology, juvenile justice, and the scientific study of offenders. Based on five years of intensive research with more than a thousand young repeat offenders at Chicago’s Juvenile Psychopathic Institute, Healy challenged the prevailing search for a single explanation of criminal behavior. Instead, he argued that delinquency could be understood only by examining the individual offender and the complex interaction of psychological, physical, developmental, family, and environmental factors.

Healy’s central question remains strikingly contemporary: not simply what crime was committed, but why did this particular person commit it? His approach combined family and developmental histories, medical examinations, psychological testing, investigation of home and social environments, and extensive personal interviews. He emphasized diagnosis, prognosis, treatment, and follow-up rather than reliance upon punishment or abstract theories of criminality.

This Read-Me.Org Modernized-Classic makes Healy’s massive original work accessible to contemporary readers. The original volume of more than 800 pages has been abridged to approximately one-quarter of its length while retaining Healy’s organization and central arguments. The text has been rendered in modern English, representative case histories have been condensed, and editorial notes identify obsolete terminology and historically limited assumptions. Review and discussion questions make the volume particularly suitable for students and classroom use.

Both a historical document and a surprisingly modern argument for individualized justice, The Individual Delinquent illuminates the emergence of psychological and clinical approaches to crime and demonstrates why understanding the person behind the offense became a fundamental concern of twentieth-century criminology.

Mental Conflicts and Misconduct is a pioneering work in the history of psychology, criminology, and juvenile justice. First published in 1917, physician and juvenile court reformer William Healy challenged the prevailing belief that young offenders were simply bad, immoral, or mentally defective. Drawing on dozens of real-life case studies, Healy argued that many acts of delinquency arise from hidden emotional conflicts rooted in childhood experiences, secrets, fears, and unresolved traumas.

Working with young people who stole, ran away, lied, fought, or repeatedly broke the law, Healy uncovered a striking pattern. Beneath seemingly senseless misconduct often lay painful memories, disturbing knowledge, family secrets, or experiences that children felt unable to discuss with trusted adults. These buried conflicts, he believed, could exert a powerful influence on behavior long after the original events had been forgotten or repressed.

This modernized and abridged Read-Me.Org edition makes Healy's landmark study accessible to contemporary readers while preserving all forty of his remarkable case histories and the core of his argument. The book reveals the origins of ideas that would later influence child guidance clinics, trauma-informed care, psychological treatment, and modern approaches to juvenile justice.

Although some of Healy's assumptions reflect the limitations of his era, many of his insights remain surprisingly relevant. His emphasis on listening to children, understanding individual circumstances, and addressing underlying causes rather than relying solely on punishment anticipated developments that continue to shape psychology and criminal justice today.

Part historical document, part psychological investigation, and part humanitarian appeal, Mental Conflicts and Misconduct remains an important classic for students of psychology, criminology, social work, education, and anyone interested in the complex relationship between childhood experience and human behavior.

Tackling street gangs has recently been highlighted as a priority for public health. In this paper, the four components of a public health approach were reviewed: (1) surveillance, (2) identifying risk and protective factors, (3) developing and evaluating interventions at primary prevention, secondary prevention, and tertiary intervention stages, and (4) implementation of evidence-based programs. Findings regarding the effectiveness of prevention and intervention programs for street gang members were mixed, with unclear goals/objectives, limited theoretical foundation, and a lack of consistency in program implementation impeding effectiveness at reducing street gang involvement. This paper proposes that the Good Lives Model (GLM), a strengths-based framework for offender rehabilitation, provides an innovative approach to street gang intervention. Utilizing approach-goals, the GLM assumes that improving an individual’s internal skills and external opportunities will reduce the need to become involved in street gangs. Wrapping the GLM framework around current evidence-based interventions (e.g., Functional Family Therapy) increases client engagement and motivation to change, which is notably poor amongst those at risk of, or involved in, street gangs.
