The present study examined several distinct indicators of regulation (i.e., task-based executive function, surveyed child effortful control, and surveyed household chaos) as moderators of longitudinal bidirectional links between developmental changes in harsh parenting (HP) and child externalizing behaviors (EXT) from age 9 to 14 years. The sample included 311 children (50.4% female; 111 White or European American; 97 Hispanic or Latino; 103 Black or African American). We conducted cross-lagged panel analyses and utilized multiple reporters (mother, father, and child). Regarding bidirectionality between HP and EXT, findings were mixed depending on informant, but overall more child effects than parent effects or bidirectional effects emerged. Child and household regulation moderated certain effects, providing initial evidence of the potential role of regulations in bidirectional links between HP and EXT. The present study adds impetus to considering child self-regulation and household chaos as critical features influencing the bidirectional link between parenting and child functioning.

One species-general life history (LH) principle posits that challenging childhood environments are coupled with a fast or faster LH strategy and associated behaviors, while secure and stable childhood environments foster behaviors conducive to a slow or slower LH strategy. This coupling between environments and LH strategies is based on the assumption that individuals’ internal traits and states are independent of their external surroundings. In reality, individuals respond to external environmental conditions in alignment with their intrinsic vitality, encompassing both physical and mental states. The present study investigated attachment as an internal mental state, examining its role in mediating and moderating the association between external environmental adversity and fast LH strategies. A sample of 1169 adolescents (51% girls) from 9 countries was tracked over 10 years, starting from age 8. The results confirm both mediation and moderation and, for moderation, secure attachment nullified and insecure attachment maintained the environment-LH coupling. These findings suggest that attachment could act as an internal regulator, disrupting the contingent coupling between environmental adversity and a faster pace of life, consequently decelerating human LH.

It is unclear how much adolescents’ lives were disrupted throughout the COVID-19 pandemic or what risk factors predicted such disruption. To answer these questions, 1,080 adolescents in 9 nations were surveyed 5 times from March 2020 to July 2022. Rates of adolescent COVID-19 life disruption were stable and high. Adolescents who, compared to their peers, lived in nations with higher national COVID-19 death rates, lived in nations with less stringent COVID-19 mitigation strategies, had less confidence in their government’s response to COVID-19, complied at higher rates with COVID-19 control measures, experienced the death of someone they knew due to COVID-19, or experienced more internalizing, externalizing, and smoking problems reported more life disruption due to COVID-19 during part or all of the pandemic. Additionally, when, compared to their typical levels of functioning, adolescents experienced spikes in national death rates, experienced less stringent COVID-19 mitigation measures, experienced less confidence in government response to the COVID-19 pandemic, complied at higher rates with COVID-19 control measures, experienced more internalizing problems, or smoked more at various periods during the pandemic, they also experienced more COVID-19 life disruption. Collectively, these findings provide new insights that policymakers can use to prevent the disruption of adolescents’ lives in future pandemics.

Research has suggested that childhood-onset conduct problems (CPs) are more strongly related to individual predispositions, whereas adolescent-onset CP is more strongly associated with social factors, such as peer delinquency. Neighborhood disadvantage (ND) increases the risk for associating with deviant peers. Thus, peer delinquency could mediate the relationship between ND and adolescent-onset CP. This mediational hypothesis has not been tested previously. We tested this hypothesis in 1,127 justice-involved adolescent males using self-reported delinquency and official arrest records over 3 years after the youth’s first arrest as outcomes. Predictors were self-reported and census-derived indicators of ND and self-reported peer delinquency. Age of onset moderated the associations between self-reported ND and arrests and between self-report of peer delinquency and arrests. In both cases, the association was stronger for those with adolescent-onset CP. Peer delinquency mediated all relationships between ND and CP. Our results also showed some unexpected differences in associations depending on whether self-reported ND or census-derived indicators were used as predictors. Specifically, census-derived ND was negatively related to self-reported offending, which could be due to the use of an arrested sample and the need for youth in more advantaged neighborhoods to show a more severe pattern of antisocial behavior to be arrested.

Research on proactive and reactive aggression has identified covariates unique to each function of aggression, but hypothesized correlates have often not been tested with consideration of developmental changes in or the overlap between the types of aggression. The present study examines the unique developmental trajectories of proactive and reactive aggression over adolescence and young adulthood and tests these trajectories’ associations with key covariates: callous–unemotional (CU) traits, impulsivity, and internalizing emotions. In a sample of 1,211 justice-involved males (ages 15–22), quadratic growth models (i.e., intercepts, linear slopes, and quadratic slopes) of each type of aggression were regressed onto quadratic growth models of the covariates while controlling for the other type of aggression. After accounting for the level of reactive aggression, the level of proactive aggression was predicted by the level of CU traits. However, change in proactive aggression over time was not related to the change in any covariates. After accounting for proactive aggression, reactive aggression was predicted by impulsivity, both at the initial level and in change over time. Results support that proactive and reactive aggression are unique constructs with separate developmental trajectories and distinct covariates.

Youth in the juvenile justice system evince high rates of mental health symptoms, including anxiety and depression. How these symptom profiles change after first contact with the justice system and – importantly – how they are related to re-offending remains unclear. Here, we use latent growth curve modeling to characterize univariate and multivariate growth of anxiety, depression, and re-offending in 1216 male adolescents over 5 years following their first arrest. Overall, the group showed significant linear and quadratic growth in internalizing symptoms and offending behaviors over time such that levels decreased initially after first arrest followed by a small but significant upturn occurring a few years later. Crucially, multivariate growth models revealed strong positive relationships between the rates of growth in internalizing symptoms and offending behaviors such that improvements in mental health related to greater decreases in offending, and vice versa. These results highlight the reciprocal nature of internalizing and externalizing problems in adolescence, underscoring the importance of considering mental health alongside offending in the juvenile justice system.

Prior to the COVID-19 pandemic, adolescents (N = 1,330; Mages = 15 and 16; 50% female), mothers, and fathers from nine countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, United States) reported on adolescents’ internalizing and externalizing problems, adolescents completed a lab-based task to assess tendency for risk-taking, and adolescents reported on their well-being. During the pandemic, participants (Mage = 20) reported on changes in their internalizing, externalizing, and substance use compared to before the pandemic. Across countries, adolescents’ internalizing problems pre-pandemic predicted increased internalizing during the pandemic, and poorer well-being pre-pandemic predicted increased externalizing and substance use during the pandemic. Other relations varied across countries, and some were moderated by confidence in the government’s handling of the pandemic, gender, and parents’ education.

The current study advances past research by studying the impact of juvenile justice decision making with a geographically and ethnically diverse sample (N = 1,216) of adolescent boys (ages 13–17 years) for the 5 years following their first arrest. Importantly, all youth in the study were arrested for an eligible offense of moderate severity (e.g., assault, theft) to evaluate whether the initial decision to formally (i.e., sentenced before a judge) or informally (i.e., diverted to community service) process the youth led to differences in outcomes. The current study also advanced past research by using a statistical approach that controlled for a host of potential preexisting vulnerabilities that could influence both the processing decision and the youth's outcomes. Our findings indicated that youth who were formally processed during adolescence were more likely to be re-arrested, more likely to be incarcerated, engaged in more violence, reported a greater affiliation with delinquent peers, reported lower school enrollment, were less likely to graduate high school within 5 years, reported less ability to suppress aggression, and had lower perceptions of opportunities than informally processed youth. Importantly, these findings were not moderated by the age of the youth at his first arrest or his race and ethnicity. These results have important implications for juvenile justice policy by indicating that formally processing youth not only is costly, but it can reduce public safety and reduce the adolescent's later potential contributions to society.

This study used data from 12 cultural groups in 9 countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, and United States; N = 1,315) to investigate bidirectional associations between parental warmth and control, and child externalizing and internalizing behaviors. In addition, the extent to which these associations held across mothers and fathers and across cultures with differing normative levels of parent warmth and control were examined. Mothers, fathers, and children completed measures when children were ages 8 to 13. Multiple-group autoregressive cross-lagged structural equation models revealed that evocative child-driven effects of externalizing and internalizing behavior on warmth and control are ubiquitous across development, cultures, mothers, and fathers. Results also reveal that parenting effects on child externalizing and internalizing behaviors, though rarer than child effects, extend into adolescence when examined separately in mothers and fathers. Father-based parent effects were more frequent than mother effects. Most parent- and child-driven effects appear to emerge consistently across cultures. The rare culture-specific parenting effects suggested that occasionally the effects of parenting behaviors that run counter to cultural norms may be delayed in rendering their protective effect against deleterious child outcomes.

Using multilevel models, we examined mother-, father-, and child-reported (N = 1,336 families) externalizing behavior problem trajectories from age 7 to 14 in nine countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States). The intercept and slope of children's externalizing behavior trajectories varied both across individuals within culture and across cultures, and the variance was larger at the individual level than at the culture level. Mothers’ and children's endorsement of aggression as well as mothers’ authoritarian attitudes predicted higher age 8 intercepts of child externalizing behaviors. Furthermore, prediction from individual-level endorsement of aggression and authoritarian attitudes to more child externalizing behaviors was augmented by prediction from cultural-level endorsement of aggression and authoritarian attitudes, respectively. Cultures in which father-reported endorsement of aggression was higher and both mother- and father-reported authoritarian attitudes were higher also reported more child externalizing behavior problems at age 8. Among fathers, greater attributions regarding uncontrollable success in caregiving situations were associated with steeper declines in externalizing over time. Understanding cultural-level as well as individual-level correlates of children's externalizing behavior offers potential insights into prevention and intervention efforts that can be more effectively targeted at individual children and parents as well as targeted at changing cultural norms that increase the risk of children's and adolescents’ externalizing behavior.

The current study advanced research on the link between community violence exposure and aggression by comparing the effects of violence exposure on different functions of aggression and by testing four potential (i.e., callous–unemotional traits, consideration of others, impulse control, and anxiety) mediators of this relationship. Analyses were conducted in an ethnically/racially diverse sample of 1,216 male first-time juvenile offenders (M = 15.30 years, SD = 1.29). Our results indicated that violence exposure had direct effects on both proactive and reactive aggression 18 months later. The predictive link of violence exposure to proactive aggression was no longer significant after controlling for proactive aggression at baseline and the overlap with reactive aggression. In contrast, violence exposure predicted later reactive aggression even after controlling for baseline reactive aggression and the overlap with proactive aggression. Mediation analyses of the association between violence exposure and reactive aggression indicated indirect effects through all potential mediators, but the strongest indirect effect was through impulse control. The findings help to advance knowledge on the consequences of community violence exposure on justice-involved youth.

Using data from 1,177 families in eight countries (Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States), we tested a conceptual model of direct effects of childhood family adversity on subsequent externalizing behaviors as well as indirect effects through psychological mediators. When children were 9 years old, mothers and fathers reported on financial difficulties and their use of corporal punishment, and children reported perceptions of their parents’ rejection. When children were 10 years old, they completed a computerized battery of tasks assessing reward sensitivity and impulse control and responded to questions about hypothetical social provocations to assess their hostile attributions and proclivity for aggressive responding. When children were 12 years old, they reported on their externalizing behavior. Multigroup structural equation models revealed that across all eight countries, childhood family adversity had direct effects on externalizing behaviors 3 years later, and childhood family adversity had indirect effects on externalizing behavior through psychological mediators. The findings suggest ways in which family-level adversity poses risk for children's subsequent development of problems at psychological and behavioral levels, situated within diverse cultural contexts.

In the psychological tradition, desistance from antisocial behavior is viewed as the product of psychosocial maturation, including increases in the ability to control impulses, consider the implications of one's actions on others, delay gratification in the service of longer term goals, and resist the influences of peers. The present study investigates how individual variability in the development of psychosocial maturity is associated with desistance from antisocial behavior in a sample of 1,088 serious juvenile offenders followed from adolescence to early adulthood (ages 14–25). We find that psychosocial maturity continues to develop to the midtwenties and that different developmental patterns of maturation are found among those who desist and those who persist in antisocial behavior. Compared to individuals who desisted from antisocial behavior, youths who persisted exhibited diminished development of psychosocial maturity. Moreover, earlier desistance compared to later desistance is linked to greater psychosocial maturity, suggesting that there is an association between desistance from antisocial behavior and normative increases in psychosocial maturity.

Improvements in temperance, perspective, and responsibility are a part of typical development of psychosocial maturity during adolescence. The existing literature suggests that the developmental course of psychosocial maturity is influenced by normative variations in social context, but little is known about how atypical contexts, such as incarceration, influence its development. The study investigates how the development of psychosocial maturity is affected by incarceration, using data from a 7-year longitudinal study of 1,171 adolescent males. We compared the effects of confinement in juvenile facilities with varying degrees of focus on incarceration versus rehabilitation (i.e., secure vs. residential treatment facilities) and tested whether facility quality and age at incarceration moderate the effect of incarceration on psychosocial maturity. The results indicate that incarceration in a secure setting, but not a residential treatment facility, is associated with a short-term decline in temperance and responsibility. The total amount of time incarcerated in a residential treatment facility, but not a secure setting, had a negative effect on the developmental trajectory of psychosocial maturity. Age at incarceration, but not the facility quality, moderated the effect of recent incarceration: older youths were more susceptible to short-term negative effects of recent incarceration in a secure setting, but they also benefited more than younger participants from short-term positive effects of incarceration in a residential treatment setting. Furthermore, youths who perceived their incarceration setting as unsafe evinced a decline in temperance. Future research and policy implications are discussed.
