Kindergarten conduct problems are associated with monetized outcomes in adolescence and adulthood.

BACKGROUND: Across several sites in the United States, we examined whether kindergarten conduct problems among mostly population-representative samples of children were associated with increased criminal and related (criminal + lost offender productivity + victim; described as criminal + victim hereafter) costs across adolescence and adulthood, as well as government and medical services costs in adulthood. METHODS: Participants (N = 1,339) were from two multisite longitudinal studies: Fast Track (n = 754) and the Child Development Project (n = 585). Parents and teachers reported on kindergarten conduct problems, administrative and national database records yielded indexes of criminal offending, and participants self-reported their government and medical service use. Outcomes were assigned costs, and significant associations were adjusted for inflation to determine USD 2020 costs. RESULTS: A 1SD increase in kindergarten conduct problems was associated with a $21,934 increase in adolescent criminal + victim costs, a $63,998 increase in adult criminal + victim costs, a $12,753 increase in medical services costs, and a $146,279 increase in total costs. In the male sample, a 1SD increase in kindergarten conduct problems was associated with a $28,530 increase in adolescent criminal + victim costs, a $58,872 increase in adult criminal + victim costs, and a $144,140 increase in total costs. In the female sample, a 1SD increase in kindergarten conduct problems was associated with a $15,481 increase in adolescent criminal + victim costs, a $62,916 increase in adult criminal + victim costs, a $24,105 increase in medical services costs, and a $144,823 increase in total costs. CONCLUSIONS: This investigation provides evidence of the long-term costs associated with early-starting conduct problems, which is important information that can be used by policymakers to support research and programs investing in a strong start for children.

How adolescents' lives were disrupted over the course of the COVID-19 pandemic: A longitudinal investigation in 12 cultural groups in 9 nations from March 2020 to July 2022.

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.

Attachment security, environmental adversity, and fast life history behavioral profiles in human adolescents.

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.

The impact of COVID-19 on the peer relationships of adolescents around the world: A rapid systematic review.

The main objective of this rapid systematic review was to examine how the COVID-19 pandemic impacted peer relationships for adolescents (10-25 years of age) around the globe. We focused on four indices of peer relationships: (1) loneliness, (2) social connectedness, (3) social support, and (4) social media use. In addition, we examined gender and age differences. Four databases (APA PsychInfo, PubMed, Scopus, and Web of Science) were searched for articles published from January 2020 to November 2022. A total of 96 studies (cross-sectional: n = 66, longitudinal: n = 30, quantitative: n = 67, qualitative: n = 12, mixed-methods: n = 17) met our inclusion criteria (empirical observational studies with data on at least one of the indices of interest, cross-sectional data on COVID-19-related experiences or longitudinal data collected during the pandemic, age range of 10-25 years, typically developing adolescents). We extracted data and conducted a narrative synthesis. Findings suggest that COVID-19 disruptions negatively impacted peer relationships for youth. Most studies reported either an increase in loneliness over the course of the pandemic or a positive association between loneliness and COVID-19-related experiences. Similar findings were observed for increased social media use as a means of continued communication and connection. Fewer studies focused on social support but those that did reported a decrease or negative association with COVID-19-related experiences. Lastly, findings suggest a mixed impact on social connectedness, which might be due to the strengthening of closer ties and weakening of more distant relationships. Results for gender differences were mixed, and a systematic comparison of differences across ages was not possible. The heterogeneity in measures of COVID-19-related experiences as well as timing of data collection prevented a more nuanced examination of short and more long-term impacts.

Fast Track Intervention Effects and Mechanisms of Action Through Established Adulthood.

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.

Investigating Longitudinal Trajectories of COVID-19 Disruption: Methodological Challenges and Recommendations.

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.

Adolescents' relationships with parents and romantic partners in eight countries.

INTRODUCTION: Creating romantic relationships characterized by high-quality, satisfaction, few conflicts, and reasoning strategies to handle conflicts is an important developmental task for adolescents connected to the relational models they receive from their parents. This study examines how parent-adolescent conflicts, attachment, positive parenting, and communication are related to adolescents' romantic relationship quality, satisfaction, conflicts, and management. METHOD: We interviewed 311 adolescents at two time points (females = 52%, ages 15 and 17) in eight countries (China, Colombia, Italy, Kenya, the Philippines, Sweden, Thailand, and the United States). Generalized and linear mixed models were run considering the participants' nesting within countries. RESULTS: Adolescents with negative conflicts with their parents reported low romantic relationship quality and satisfaction and high conflicts with their romantic partners. Adolescents experiencing an anxious attachment to their parents reported low romantic relationship quality, while adolescents with positive parenting showed high romantic relationship satisfaction. However, no association between parent-adolescent relationships and conflict management skills involving reasoning with the partner was found. No associations of parent-adolescent communication with romantic relationship dimensions emerged, nor was there any effect of the country on romantic relationship quality or satisfaction. CONCLUSION: These results stress the relevance of parent-adolescent conflicts and attachment as factors connected to how adolescents experience romantic relationships.

Developmental Trajectories of Parental Self-Efficacy as Children Transition to Adolescence in Nine Countries: Latent Growth Curve Analyses.

Little is known about the developmental trajectories of parental self-efficacy as children transition into adolescence. This study examined parental self-efficacy among mothers and fathers over 3 1/2 years representing this transition, and whether the level and developmental trajectory of parental self-efficacy varied by cultural group. Data were drawn from three waves of the Parenting Across Cultures (PAC) project, a large-scale longitudinal, cross-cultural study, and included 1178 mothers and 1041 fathers of children who averaged 9.72 years of age at T1 (51.2% girls). Parents were from nine countries (12 ethnic/cultural groups), which were categorized into those with a predominant collectivistic (i.e., China, Kenya, Philippines, Thailand, Colombia, and Jordan) or individualistic (i.e., Italy, Sweden, and USA) cultural orientation based on Hofstede's Individualism Index (Hofstede Insights, 2021). Latent growth curve analyses supported the hypothesis that parental self-efficacy would decline as children transition into adolescence only for parents from more individualistic countries; parental self-efficacy increased over the same years among parents from more collectivistic countries. Secondary exploratory analyses showed that some demographic characteristics predicted the level and trajectory of parental self-efficacy differently for parents in more individualistic and more collectivistic countries. Results suggest that declines in parental self-efficacy documented in previous research are culturally influenced.

Cultural values, parenting and child adjustment: Introduction to the special issue.

This introduction provides an overview of the major constructs that are the focus of this Special Issue. Individualism and collectivism have been the cornerstones of theoretical work on cultural values in psychological science, and conformity is an important component of theories related to motivational values. Individualism, collectivism and conformity values are reviewed in relation to parenting (warmth, knowledge solicitation, rules/limit-setting, parents' expectations regarding children's family obligations) and children's adjustment (internalising and externalising behaviours). Background on the Parenting Across Cultures project, a study of children, mothers and fathers, in nine countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand and the United States) is provided as a prelude to the country-specific papers from each of these countries that follow in the rest of the Special Issue before a final concluding paper that focuses on between-country versus within-country variation in cultural values, parenting and children's adjustment.

Bidirectional longitudinal associations between parental self-efficacy and child rule-breaking behaviours: A random-intercept cross-lagged panel study.

Parental self-efficacy (PSE) is a pivotal determinant of change in children's adjustment. However, not only has previous research shown that PSE plays a protective role for children's rule-breaking (RB) behaviours (i.e., parent-driven process), but RB also can reduce parents' PSE over-time (i.e., child-driven process). This study examined the bidirectional longitudinal associations between PSE and RB behaviours by disentangling maternal from paternal influences and between- from within-person effects. In the present seven-wave longitudinal study involving 200 Italian children (T1: Mage = 9.80, SD = 0.65; 50.5% girls), their mothers (N = 200) and fathers (N = 190), two random-intercept cross-lagged panel models (one for mothers and one for fathers) were used to explore whether: (a) stable parts of PSE and RB were related to each other, (b) higher levels of PSE were associated with lower levels of RB at a given time point, and (c) higher levels of PSE at a given time point were associated with future lower levels of RB. Results provided evidence both for a parent- and a child-driven process between mothers' PSE and children's RB behaviours. However, these results were not replicated for fathers. Implications are discussed.

Cultural values, parenting, and child adjustment in the United States.

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.

Individualism, collectivism and conformity in nine countries: Relations with parenting and child adjustment.

This study investigated how individualism, collectivism and conformity are associated with parenting and child adjustment in 1297 families with 10-year-old children from 13 cultural groups in nine countries. With multilevel models disaggregating between- and within-culture effects, we examined between- and within-culture associations between maternal and paternal cultural values, parenting dimensions and children's adjustment. Mothers from cultures endorsing higher collectivism and fathers from cultures endorsing lower individualism engage more frequently in warm parenting behaviours. Mothers and fathers with higher-than-average collectivism in their culture reported higher parent warmth and expectations for children's family obligations. Mothers with higher-than-average collectivism in their cultures more frequently reported warm parenting and fewer externalising problems in children, whereas mothers with higher-than-average individualism in their culture reported more child adjustment problems. Mothers with higher-than-average conformity values in their culture reported more father-displays of warmth and greater mother-reported expectations for children's family obligations. Fathers with higher-than-average individualism in their culture reported setting more rules and soliciting more knowledge about their children's whereabouts. Fathers who endorsed higher-than-average conformity in their culture displayed more warmth and expectations for children's family obligations and granted them more autonomy. Being connected to an interdependent, cohesive group appears to relate to parenting and children's adjustment.

Intergenerational effects of the Fast Track intervention on the home environment: A randomized control trial.

BACKGROUND: 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. METHODS: 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 https://osf.io/dz9t5 and the Fast Track trial was registered at clinicaltrials.gov (NCT01653535). RESULTS: 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. CONCLUSIONS: Childhood assignment to Fast Track has some beneficial effects for girls, but not boys, on the family environments these individuals formed as adults 18 years later.

Predictors of problematic adult alcohol, cannabis, and other substance use: A longitudinal study of two samples.

This study examined whether a key set of adolescent and early adulthood risk factors predicts problematic alcohol, cannabis, and other substance use in established adulthood. Two independent samples from the Child Development Project (CDP; n = 585; 48% girls; 81% White, 17% Black, 2% other race/ethnicity) and Fast Track (FT; n = 463; 45% girls; 52% White, 43% Black, 5% other race/ethnicity) were recruited in childhood and followed through age 34 (CDP) or 32 (FT). Predictors of substance use were assessed in adolescence based on adolescent and parent reports and in early adulthood based on adult self-reports. Adults reported their own problematic substance use in established adulthood. In both samples, more risk factors from adolescence and early adulthood predicted problematic alcohol use in established adulthood (compared to problematic cannabis use and other substance use). Externalizing behaviors and prior substance use in early adulthood were consistent predictors of problematic alcohol and cannabis misuse in established adulthood across samples; other predictors were specific to the sample and type of substance misuse. Prevention efforts might benefit from tailoring to address risk factors for specific substances, but prioritizing prevention of externalizing behaviors holds promise for preventing both alcohol and cannabis misuse in established adulthood.

Pre-pandemic psychological and behavioral predictors of responses to the COVID-19 pandemic in nine countries.

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.

Predicting child aggression: The role of parent and child endorsement of reactive aggression across 13 cultural groups in 9 nations.

Parent and child endorsement of reactive aggression both predict the emergence of child aggression, but they are rarely studied together and in longitudinal contexts. The present study does so by examining the unique predictive effects of parent and child endorsement of reactive aggression at age 8 on child aggression at age 9 in 1456 children from 13 cultural groups in 9 nations. Multiple group structural equation models explored whether age 8 child and parent endorsement of reactive aggression predicted subsequent age 9 child endorsement of reactive aggression and child aggression, after accounting for prior child aggression and parent education. Results revealed that greater parent endorsement of reactive aggression at age 8 predicted greater child endorsement of aggression at age 9, that greater parent endorsement of reactive aggression at age 8 uniquely predicted greater aggression at age 9 in girls, and that greater child endorsement of reactive aggression at age 8 uniquely predicted greater aggression at age 9 in boys. All three of these associations emerged across cultures. Implications of, and explanations for, study findings are discussed.

Emotion-related Self-regulation Profiles in Early Adolescence: A Cross-National Study.

Emotionality and self-regulation are crucial for positive development, especially during early adolescence when youths experience normative increases in behavioral problems and declines in prosociality. Using Latent Profile Analysis (LPA-a person-oriented technique to identify patterns of functioning within individuals), we identified youths' profiles based on dimensions of mother-reported negative emotionality (NE; anger/frustration, sadness/depressive mood), and Effortful Control (EC; attentional, activation and inhibitory control) and examined concurrent associations with self- and mother-reported aggressive and prosocial behaviors. We included a cross-national sample of 530 youths (M age =11.43; 49% males) from Colombia (17%), Italy (36%), and United States (47%). We identified four profiles: Adjusted (38%; low NE; high EC)-lowest aggression, highest prosociality; Average (34%; average NE and EC)-average aggression and prosociality; Emotional-regulated (20%; high NE; average EC)-average aggression and high prosociality; and Emotional-dysregulated (8%; high NE; low EC)-highest aggression, low prosociality. We highlight associations of different emotion-regulation patterns with specific behavioral responses in early adolescence.

Predictive Validity of Adolescent Callous-Unemotional Traits and Conduct Problems with Respect to Adult Outcomes: High- and Low-Risk Samples.

Current understanding of the predictive validity of callous-unemotional (CU) traits is limited by (a) the focus on externalizing psychopathology and antisocial behaviors, (b) a lack of long-term prospective longitudinal data, (c) samples comprised of high-risk or low-risk individuals. We tested whether adolescent CU traits and conduct problems were associated with theoretically relevant adult outcomes 12-18 years later. Participants were drawn from two studies: higher-risk Fast Track (FT; n = 754) and lower-risk Child Development Project (CDP; n = 585). FT: conduct problems positively predicted externalizing and internalizing psychopathology and partner violence, and negatively predicted health, wellbeing, and education. Three conduct problems × CU traits interaction effects were also found. CDP: CU traits positively predicted depression and negatively predicted health and education; conduct problems positively predicted externalizing and internalizing psychopathology and substance use, and negatively predicted wellbeing. CU traits did not provide incremental predictive validity for multiple adult outcomes relative to conduct problems.

The Intergenerational Transmission of Maladaptive Parenting and its Impact on Child Mental Health: Examining Cross-Cultural Mediating Pathways and Moderating Protective Factors.

Using a sample of 1338 families from 12 cultural groups in 9 nations, we examined whether retrospectively remembered Generation 1 (G1) parent rejecting behaviors were passed to Generation 2 (G2 parents), whether such intergenerational transmission led to higher Generation 3 (G3 child) externalizing and internalizing behavior at age 13, and whether such intergenerational transmission could be interrupted by parent participation in parenting programs or family income increases of > 5%. Utilizing structural equation modeling, we found that the intergenerational transmission of parent rejection that is linked with higher child externalizing and internalizing problems occurs across cultural contexts. However, the magnitude of transmission is greater in cultures with higher normative levels of parent rejection. Parenting program participation broke this intergenerational cycle in fathers from cultures high in normative parent rejection. Income increases appear to break this intergenerational cycle in mothers from most cultures, regardless of normative levels of parent rejection. These results tentatively suggest that bolstering protective factors such as parenting program participation, income supplementation, and (in cultures high in normative parent rejection) legislative changes and other population-wide positive parenting information campaigns aimed at changing cultural parenting norms may be effective in breaking intergenerational cycles of maladaptive parenting and improving child mental health across multiple generations.

Parenting, Adolescent Sensation Seeking, and Subsequent Substance Use: Moderation by Adolescent Temperament.

Although previous research has identified links between parenting and adolescent substance use, little is known about the role of adolescent individual processes, such as sensation seeking, and temperamental tendencies for such links. To test tenets from biopsychosocial models of adolescent risk behavior and differential susceptibility theory, this study investigated longitudinal associations among positive and harsh parenting, adolescent sensation seeking, and substance use and tested whether the indirect associations were moderated by adolescent temperament, including activation control, frustration, sadness, and positive emotions. Longitudinal data reported by adolescents (n = 892; 49.66% girls) and their mothers from eight cultural groups when adolescents were ages 12, 13, and 14 were used. A moderated mediation model showed that parenting was related to adolescent substance use, both directly and indirectly, through sensation seeking. Indirect associations were moderated by adolescent temperament. This study advances understanding of the developmental paths between the contextual and individual factors critical for adolescent substance use across a wide range of cultural contexts.
