Numerous studies have identified a late-onset pattern of offending, yet debate remains over whether this pattern is real or attributable to measurement error. The goal of the present study is to identify whether this late-onset trajectory exists. We used prospective longitudinal data from the Rochester Youth Development Study and group-based trajectory modeling to identify distinct developmental patterns in self-reported incidence of general delinquency from approximately ages 14 to age 31. We then examined and compared the means of general, violent, street, and property offending for individuals belonging to late bloomer, chronic, and low-level offending trajectories across three periods: 1) pre-onset (ages 14-17), 2) post-onset (ages 29-31), and, 3) for a subset of participants participating in a follow-up study, post-trajectory (ages 32-40). Results confirmed the existence of a distinct late bloomers offending trajectory characterized by low rates of delinquency throughout adolescence and high levels throughout adulthood. Furthermore, late bloomers had similar mean levels of delinquency as low-level offenders and that were considerably lower than chronic offenders in the pre-onset period and similar means of offending as chronic offenders that were considerably higher than low-level offenders in the post-onset and post-trajectory periods. Comparisons of these three groups on adolescent risk and protective factors indicated that late bloomers were more similar to individuals in the low-level trajectory and had fewer risk and more protective factors than individuals following a chronic trajectory. Contrary to prior work which attributes late-onset offending to reliance on official data which fails to detect adolescent offending, late bloomer offending appears to be a genuine phenomenon. These results lend greater support to dynamic theories of crime.

The Zurich Project on the Social Development from Childhood to Adulthood (z-proso) began in 2004 in response to the need for a better evidence base to support optimal child social development and prevent crime and violence. Since then, the study has tracked the development of a diverse sample of youths (N = 1,675 in the target sample; ~50% female) from age 7 (n = 1,360) to age 20 (n = 1,180), with primary data collection waves at ages 7, 8, 9, 10, 11, 12, 13, 15, 17, and 20. The study uses a multi-method, multi-informant design that combines teacher, youth, and parent reports with observational and behavioural measures, biosampling, functional imaging, and ecological momentary assessment. Analyses of the data have contributed important evidence to a diversity of topics in child and adolescent development, illuminating the developmental roots of crime and aggression, the impacts of exposure to different forms and combinations of victimisation, and trajectories of mental health and neurodevelopmental symptoms.

The dual systems model is a developmental cognitive framework found to have utility for explaining engagement in antisocial behavior. Centered on differential development of sensation-seeking and impulse control, the theory has risen to prominence. Despite this, there is limited understanding of how exposure to violence may drive development in these outcomes. Specifically, knowledge is limited in terms of how different forms of exposure to violence (direct victimization, witnessed violence) may influence development of these constructs differently and whether the age at which exposure occurs matters in this regard. The present study utilized the Pathways to Desistance data to examine these relationships. Mixed effects modeling was used to analyze the data. Findings indicated that both direct victimization and witnessed violence predicted change in both dual systems constructs. However, the salience of witnessed violence for predicting sensation-seeking declined in a linear manner as participants got older. Implications are discussed.
