Background: This article is dedicated to David Farrington who was a giant in criminology and, in particular, a pioneer in studying developmental pathways of delinquent and antisocial behaviour. Numerous studies followed his work. Systematic reviews of his and others' research described between two and seven (mainly 3–5) trajectories. The variation is due to the age of individuals, kind and seriousness of problem behaviour, data sources, assessment methods and cultural context. Reviews stated a lack of research on very early starting problem behaviour, broad developmental outcomes, data from multiple informants and (beyond description) on risk and protective factors or potential causes of the different trajectories. Aims: The present study addresses these issues in a prospective longitudinal design and test of the concept of antisocial potential (AP) in Farrington's ICAP theory. Methods: Data on more than 600 children and their families were gathered in a prospective longitudinal design over 10 years in Germany. To avoid potentially negative effects of criminal justice interventions, the study concentrates on child development from ages 4–5 to 6–7, 8–9, 10–12 and 13–14 years. Child externalising behaviour problems were assessed using the social behaviour questionnaire by kindergarten educators, mothers, school teachers and youth self‐reports. Developmental trajectories were analysed by general growth curve modelling (GGCM) across five time points. The prediction and explanation of different pathways included family factors (SES, stressful life events, aggressive and inconsistent parenting) and child characteristics (intelligence, resting heart rate, disruptive behaviour, temperament and social adaptability). In accordance with dose–response relationships, we also tested accumulated factors in the Cracow Risk/Needs Instrument. Results: The GGCM analysis revealed five developmental trajectories: high‐chronics (2.4%), high‐reducers (7.9%), medium‐ reducers (22.4%), late‐starters medium (8.7%) and low‐chronics (continuously unproblematic youngsters; 58.6%). Although the group with high externalising problems across all time points was rather small due to the affluent context of the region, there were significant social and individual differences between this and the other groups that fitted to ICAP theory. Furthermore, the study revealed differences between those youngsters that desisted from behaviour problems or started later. The predictive validity of accumulated factors in the Cracow Risk/Needs Instrument was very good for the comparison of the groups with persistently high versus no serious behaviour problems. Conclusions: Our results showed that different pathways of aggressive, delinquent, impulsive and other externalising behaviour already commence in early childhood. Behavioural stability (high‐ vs. low‐chronic problems) was well predicted by child and family characteristics, but there were also plausible findings on trajectories of behavioural change. Overall, the findings underline the need for early developmental prevention.

Wayward Youth by August Aichhorn delves into the complexities of working with troubled youth in a compassionate and insightful manner. Aichhorn, a renowned Austrian psychoanalyst, draws from his extensive experience to explore the psychological roots of delinquent behavior in adolescents. Through compelling case studies and thoughtful analysis, he sheds light on the inner struggles of young individuals caught in the throes of rebellion and defiance.

With empathy and wisdom, Aichhorn navigates the turbulent waters of adolescence, offering a fresh perspective on how society can better understand and support its wayward youth. Wayward Youth is a compelling read for anyone interested in the intersection of psychology, social work, and juvenile delinquency.

This report presents key findings on gang membership and knife carrying amongst a cohort of young people based on data collected by the Edinburgh Study of Youth Transitions and Crime (ESYTC). The analysis was commissioned in light of a lack of quantitative data measuring the extent of gang membership and knife crime in Scotland.

We know that most persistent offenders who cause considerable damage to society showed delinquent behavior in childhood. However, the long-term development of childhood arrestees is not well understood as longitudinal data are largely lacking. Dothese high-risk children develop long-term offense patterns? Or are even the youngest children with a police contact capable of growing into law abiding adults? Or is it both? And, in case of the latter, which childhood arrestees stop showing delinquent behavior, and which children persist in crime into early adulthood? By providinginsight into the long-term development of offending of childhood arrestees, and uncovering its explanatory factors, the current thesis improves our understanding of the delinquent development in this high-risk offender group.The current thesis reveals that, in contrast to popular belief, childhood arrestees are not predestined to develop persistent delinquent behavior, as most children are not re-arrested between the age of 12 and 25. Recidivists display heterogeneity in their re-offense patterns, with only a small group of children developing into persistent offenders. Accounting for simultaneous risk exposure across life domains proved necessary to explain why childhood arrestees follow one trajectory over another. Problems in multiple life domains were found to predict persistent offense patterns.

Sources and Solutions in South Africa. This book thoroughly and carefully reviews the evidence for risk and protective factors that influence the likelihood of young people acting aggressively. Layers of understanding are built by viewing the problem from a multitude of perspectives, including the current situation in which South African youth are growing up, perspectives from developmental psychology, the influences of race, class and gender, and of the media. The book examines the evidence for effective interventions in the contexts of young people’s lives – their homes, their schools, their leisure activities, with gangs, in the criminal justice system, in cities and neighbourhoods, and with sexual offenders. In doing so, thoughtful suggestions are made for keeping an evidence-based perspective while (necessarily) adapting interventions for developing world contexts, such as South Africa.
