Abstract: A cardinal feature of the DSM-IV diagnostic criteria for conduct disorder is the distinction between childhood- vs adolescent-onset subtypes. Whether such developmental subtypes exist in the population and have different prognoses should be rigorously tested to inform the DSM-V. To evaluate the epidemiological validity of childhood- vs adolescent-onset conduct problems in a prospective birth cohort, and to assess whether life-course-persistent conduct problems are associated with a greater adult health burden. Our s le includes 526 male study members in the Dunedin Multidisciplinary Health and Development Study, a 1-year birth cohort (April 1, 1972, through March 30, 1973). Developmental trajectories were defined using prospective ratings of conduct problems at 7, 9, 11, 13, 15, 18, 21, and 26 years of age. Health burden was assessed as mental and physical health problems at 32 years of age measured via diagnostic interviews and physical examinations. We identified the following 4 developmental subtypes of conduct problems through general growth mixture modeling: (1) childhood-onset/life-course-persistent, (2) adolescent onset, (3) childhood limited, and (4) low. At 32 years of age, study members with the life-course-persistent subtype experienced the worst health burden. To a lesser extent, those with the adolescent-onset subtype also experienced health problems. A childhood-limited subtype not specified by DSM-IV was revealed its adult health outcomes were within the range of the cohort norm. Results support the epidemiological validity of the DSM-IV conduct disorder distinction based on age of onset but highlight the need to also consider long-term persistence to refine diagnosis. Preventing and treating conduct problems has the potential to reduce the adult health burden.

Abstract: This article reports on the childhood origins and adult outcomes of female versus male antisocial behavior trajectories in the Dunedin longitudinal study. Four antisocial behavior trajectory groups were identified among females and males using general growth mixture modeling and included life-course persistent (LCP), adolescent-onset, childhood-limited, and low trajectory groups. During childhood, both LCP females and males were characterized by social, familial and neurodevelopmental risk factors, whereas those on the adolescent-onset pathway were not. At age 32, women and men on the LCP pathway were engaging in serious violence and experiencing significant mental health, physical health, and economic problems. Females and males on the adolescent-onset pathway were also experiencing difficulties at age 32, although to a lesser extent. Although more males than females followed the LCP trajectory, findings support similarities across gender with respect to developmental trajectories of antisocial behavior and their associated childhood origins and adult consequences. Implications for theory, research, and practice are discussed.

Abstract: This study examined early life antecedents of childhood social isolation, whether these factors accounted for poor outcomes of isolated children, and how these associations varied according to patterns of stability and change in childhood isolation. Participants included 2232 children from the Environmental Risk (E‐Risk) Longitudinal Twin Study. We conducted growth mixture modelling (GMM) on combined parent and teacher reports of children's social isolation when children were 5, 7, 10 and 12 years, and we assessed associations with age‐5 antecedents and age‐18 outcomes using regression analyses. We identified three linear developmental trajectories of increasing (4.75%), decreasing (5.25%) and low stable (90.00%) social isolation. Age‐5 attention deficit hyperactivity disorder (ADHD) symptoms, emotional problems, prosocial behaviours, maternal personality (openness) and size of school were associated with the decreasing trajectory of social isolation. When controlling for these antecedents, increasingly isolated children were still more likely to experience ADHD symptoms, loneliness, lower job optimism and lower physical activity at age 18. Isolated children follow distinct patterns of change over childhood and isolation seems most detrimental to health at the time it is experienced. Social isolation can be a valuable indicator of co‐occurring problems and provide targets for mental health intervention in young people.

Abstract: Maladaptive family environments harm child development and are passed across generations. Childhood interventions may break this intergenerational cycle by improving the family environments children form as adults. The present study investigates this hypothesis by examining follow‐up data collected 18 years after the end of the childhood Fast Track intervention designed to prevent externalizing problems. We examined whether Fast Track assignment from grades 1 to 10 prevented the emergence of maladaptive family environments at age 34. A total of 400 ( n = 206 in intervention condition, n = 194 controls) Fast Track participants who were parents at age 34 were surveyed about 11 aspects of their current family environment. The hypotheses and analytic plan were preregistered at osf.io/dz9t5 and the Fast Track trial was registered at clinicaltrials.gov (NCT01653535). Multiple group linear regression models revealed that mothers who participated in the Fast Track intervention as children had lower depression symptoms, alcohol problems, drug problems, corporal punishment use, and food insecurity compared to control group mothers. All effects were modest in magnitude. However, for these same mothers, the Fast Track intervention had no effect on cannabis problems, experiences of romantic partner violence, or maternal use of physical aggression or warmth with their children. Additionally, mothers in the Fast Track intervention group reported higher levels of family chaos than those in the control group, but this effect may be a byproduct of the higher number of children per household in the intervention group. No intervention effects were found for fathers who participated in the Fast Track intervention as children. Childhood assignment to Fast Track has some beneficial effects for girls, but not boys, on the family environments these in iduals formed as adults 18 years later.

Abstract: Conduct disorder (CD) is a common and highly impairing psychiatric disorder that usually emerges in childhood or adolescence and is characterized by severe antisocial and aggressive behaviour. It frequently co-occurs with attention-deficit/hyperactivity disorder (ADHD) and often leads to antisocial personality disorder in adulthood. CD affects ~3% of school-aged children and is twice as prevalent in males than in females. This disorder can be subtyped according to age at onset (childhood-onset versus adolescent-onset) and the presence or absence of callous-unemotional traits (deficits in empathy and guilt). The aetiology of CD is complex, with contributions of both genetic and environmental risk factors and different forms of interplay among the two (gene-environment interaction and correlation). In addition, CD is associated with neurocognitive impairments smaller grey matter volume in limbic regions such as the amygdala, insula and orbitofrontal cortex, and functional abnormalities in overlapping brain circuits responsible for emotion processing, emotion regulation and reinforcement-based decision-making have been reported. Lower hypothalamic-pituitary-adrenal axis and autonomic reactivity to stress has also been reported. Management of CD primarily involves parent-based or family-based psychosocial interventions, although stimulants and atypical antipsychotics are sometimes used, especially in in iduals with comorbid ADHD.
