This study advances the understanding of risk and protective factors in trajectories of conduct problems in adolescence in seven countries that differ widely on a number of sociodemographic factors as well as norms related to adolescent behavior. Youth- and parent-report data from 988 adolescents in seven countries (Colombia, Italy, Kenya, Philippines, Sweden, Thailand, and the USA) who were followed longitudinally from ages 10 to 18 (yielding 6872 total data points) were subject to latent class growth analysis. A 4-class model provided the best fit to the data: Late Starters, Alcohol Experimenters, Mid-Adolescent Starters, and Pervasive Risk Takers. The probability of membership in each class differed by country in ways that were generally consistent with country-specific norms and expectations regarding adolescent behavior. Positive parenting was associated with a lower likelihood of adolescents’ membership in the Pervasive Risk Takers class, whereas psychological control, monitoring/behavioral control, and autonomy granting were associated with a higher likelihood of membership in the Pervasive Risk Takers class. Associations between parenting and membership in the other classes suggest that some risk taking during adolescence is normative even when parenting is positive.

Introduction Prosocial behavior (i.e., voluntary actions aimed at benefiting others, such as helping, comforting, and sharing) has proven beneficial for individuals' adjustment during the transition to adolescence. However, less is known about the role of the broader sociocultural context in shaping prosocial development across different cultures. Thus, the present study explored the longitudinal trajectory of prosocial behavior in the transition to adolescence (from ages 9 to 16) by examining the role of the Human Development Index (HDI) in relation to prosocial development. Methods A sample of 915 children (Time 1: 50.5% males; M age = 9.24, SD = 0.69) across six countries (Colombia, Jordan, Italy, the Philippines, Thailand, and the United States) participated in the study. Over four time points covering 7 years, prosocial behavior was assessed using a self-report measure. Results A second-order Latent Growth Curve Model, controlling for child gender and family SES, showed that prosocial behavior remained stable in contexts with high HDI, whereas increases in prosocial behavior were evidenced as children moved into adolescence in contexts with low HDI. Moreover, cultural differences in the mean level of prosocial behavior were shown during late childhood and the earliest phase of adolescence, whereas the national development of a given context did not account for differences in prosocial behavior during late adolescence. Discussion Findings underscore that national life expectancy, education, and wealth play a role in age-related changes in other-oriented behaviors during adolescence. The role of sociocultural factors in shaping trajectories of prosocial behavior across six countries is discussed.

The aims of the current 30 year prospective study were to determine: (1) whether socially withdrawn kindergarten children are less likely than others to enter serious romantic relationships or become parents by age 34, (2) whether socially withdrawn children parent differently than non-withdrawn individuals when they grow up, and (3) whether subtypes of withdrawal are associated with different adult outcomes. Following Harrist et al. (1997), 558 kindergarten children (81% White, 17% Black) were categorized into one of the five groups: four clusters of social withdrawal ( n = 95 unsociable, 23 passive-anxious, 18 active-isolate, and 25 sad/depressed) or non-withdrawal ( n = 397), using directly observed school behavior and teacher ratings. About 30 years later ( M age = 34.45 years, SD = 0.62 years), participants self-reported on their romantic relationship and parent status and parenting warmth and harshness. Overall, the group of socially withdrawn children was no more or less likely than the non-withdrawn group to be in a current relationship or a parent, nor did they report any differences in parenting. However, the active-isolate subtype of social withdrawal, characterized by impulsivity and anger, was less likely than the non-withdrawn group to be in a current relationship ( B = −1.24, p < 0.05). This study suggests socially withdrawn children in the United States fare similarly to non-withdrawn peers in adulthood in their romantic relationships and parenting, but a subgroup of active-isolate children may be at risk of not entering adult relationships.

Early preventive interventions can improve outcomes in childhood, but the most effective interventions can continue to deliver benefits through the life course. The Fast Track intervention, a randomized controlled trial for children at risk of conduct problems, has lowered psychopathology, substance use problems, and criminality and elevated happiness at age 25. However, research has not studied whether the intervention’s effects continue further into established adulthood. In addition, little is known about the mechanisms through which the intervention may affect adult outcomes. We attempted to answer both questions by simultaneously estimating the intervention’s direct effect on adult outcomes at age 31 and the intervention’s indirect effects on those outcomes via interpersonal, intrapersonal, and academic competencies gained through the intervention. Participants included the Fast Track intervention ( n = 445; 72.4% male) and high-risk control samples ( n = 446; 66.4% male). Direct and total effects of random assignment to Fast Track on age 31 outcomes were not significant. However, our analyses showed that Fast Track’s improvements to interpersonal and intrapersonal skills in childhood served as catalysts for better life outcomes at age 31. Higher interpersonal skills led to fewer externalizing, internalizing, and substance use problems, reduced criminality and sexual partners, in addition to increased general health and full-time employment. Improved intrapersonal skills led to greater strength. There were no significant indirect pathways via academic skills. Our findings inform understanding of how a childhood preventive intervention can improve adjustment and behaviors into established adulthood.

Relatively few studies have longitudinally investigated how COVID-19 has disrupted the lives and health of youth beyond the first year of the pandemic. This may be because longitudinal researchers face complex challenges in figuring out how to code time, account for changes in COVID-19 spread, and model longitudinal COVID-19-related trajectories across environmental contexts. This manuscript considers each of these three methodological issues by modeling trajectories of COVID-19 disruption in 1080 youth from 12 cultural groups in nine nations between March 2020-July 2022 using multilevel modeling. Our findings suggest that for studies that attempt to examine cross-cultural longitudinal trajectories during COVID-19, starting such trajectories on March 11, 2020, measuring disruption along 6-month time intervals, capturing COVID-19 spread using death rates and the COVID-19 Health and Containment Index scores, and using modeling methods that combine etic and emic approaches are each especially useful. In offering these suggestions, we hope to start methodological dialogues among longitudinal researchers that ultimately result in the proliferation of research on the longitudinal impacts of COVID-19 that the world so badly needs.

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.

Cash transfer policies have been widely discussed as mechanisms to curb intergenerational transmission of socioeconomic disadvantage. In this paper, we take advantage of a large casino-funded family transfer program introduced in a Southeastern American Indian Tribe to generate difference-in-difference estimates of the link between children’s cash transfer exposure and third grade math and reading test scores of their offspring. Here we show greater math (0.25 standard deviation [SD], p =.0148, 95% Confidence Interval [CI]: 0.05, 0.45) and reading (0.28 SD, p = .0066, 95% CI: 0.08, 0.49) scores among American Indian students whose mother was exposed ten years longer than other American Indian students to the cash transfer during her childhood (or relative to the non-American Indian student referent group). Exploratory analyses find that a mother’s decision to pursue higher education and delay fertility appears to explain some, but not all, of the relation between cash transfers and children’s test scores. In this rural population, large cash transfers have the potential to reduce intergenerational cycles of poverty-related educational outcomes.

We examined whether cultural values, conformity and parenting behaviours were related to child adjustment in middle childhood in the United States. White, Black and Latino mothers ( n = 273), fathers ( n = 182) and their children ( n = 272) reported on parental individualism and collectivism, conformity values, parental warmth, monitoring, family obligation expectations, and child internalising and externalising behaviours. Mean differences, bivariate correlations and multiple regression analyses were performed on variables of interest. Collectivism in mothers and fathers was associated with family obligation expectations and parental warmth. Fathers with higher conformity values had higher expectations of children's family obligations. Child internalising and externalising behaviours were greater when Latino families subscribed to individualistic values. These results are discussed in the context of cultural values, protective and promotive factors of behaviour, and race/ethnicity in the United States.
