Abstract
In children, psychotic-like experiences (PLEs) are related to risk of psychosis, schizophrenia, and other mental disorders. Maladaptive cognitive functioning, influenced by genetic and environmental factors, is hypothesized to mediate the relationship between these factors and childhood PLEs. Using large-scale longitudinal data, we tested the relationships of genetic and environmental factors (such as familial and neighborhood environment) with cognitive intelligence and their relationships with current and future PLEs in children. We leveraged large-scale multimodal data of 6,602 children from the Adolescent Brain and Cognitive Development Study. Linear mixed model and a novel structural equation modeling (SEM) method that allows estimation of both components and factors were used to estimate the joint effects of cognitive phenotypes polygenic scores (PGSs), familial and neighborhood socioeconomic status (SES), and supportive environment on NIH Toolbox cognitive intelligence and PLEs. We adjusted for ethnicity (genetically defined), schizophrenia PGS, and additionally unobserved confounders (using computational confound modeling). Our findings indicate that lower cognitive intelligence and higher PLEs are significantly associated with lower PGSs for cognitive phenotypes, lower familial SES, lower neighborhood SES, and less supportive environments. Specifically, cognitive intelligence mediates the effects of these factors on PLEs, with supportive parenting and positive school environments showing the strongest impact on reducing PLEs. This study underscores the influence of genetic and environmental factors on PLEs through their effects on cognitive intelligence. Our findings have policy implications in that improving school and family environments and promoting local economic development may enhance cognitive and mental health in children.

Abstract
OBJECTIVE The authors sought to determine whether the Fast Track mental health intervention delivered to individuals in childhood decreased mental health problems and the need for health services among the children of these individuals. METHODS The authors examined whether Fast Track assignment in one generation of children (generation 2; G2) from grades 1 through 10 reduced parent-reported mental health problems and health services use in these children's children (generation 3; G3) 18 years later relative to a control group. The Fast Track intervention blended parent behavior-management training, child social-cognitive skills tutoring, home visits, and classroom social-ecology changes across grades 1-10 to ameliorate emerging conduct problems among the G2 children. For this study, 1,057 G3 children of Fast Track participants (N=581 intervention group, N=476 control group) were evaluated. RESULTS G3 children of G2 parents who were randomized to the Fast Track intervention group used fewer general inpatient services and fewer inpatient or outpatient mental health services compared with G3 children of G2 parents randomized to the control group. Some of these effects were mediated: randomization to Fast Track predicted fewer internalizing problems and less use of corporal punishment among G2 adults at age 25, which subsequently predicted less general inpatient service use and outpatient mental health service use among the G3 children by the time the G2 parents were 34 years old. There were no significant differences between G3 children from these two groups on the use of other health services or on mental health measures. CONCLUSIONS Fast Track was associated with lower use of general inpatient services and inpatient and outpatient mental health services intergenerationally, but effects on parent-reported mental health of the children were not apparent across generations. Investing in interventions for the mental health of children could reduce service use burdens across generations.

Abstract
Some universal prevention programs, such as Raising Healthy Children (RHC), have shown persisting and wide-ranging benefits in adulthood, long after the intervention has ended. Recent studies suggest that benefits may continue into the next generation as well. This study examines whether the RHC intervention, delivered in childhood, may promote healthy family functioning among participants who now have families of their own. Participants were drawn from the Seattle Social Development Project (SSDP), a nonrandomized controlled trial of the RHC intervention prospectively following youths from 18 elementary schools in Seattle, Washington from 1985 to 2014. Participants who became parents were enrolled in an intergenerational study, along with their oldest biological child and an additional caregiver who shared responsibility for raising the child. Ten waves of data were collected between 2002 and 2018. The present analysis includes 298 SSDP parents, 258 caregivers who identified as a parent or partner of SSDP parent ("co-parent"), and 231 offspring. The SSDP parent sample was composed of 41.6% male, 21.1% Asian or Pacific Islander, 24.2% Black or African American, 6.4% Native American, and 48.3% white individuals. No significant intervention effects were found on adult romantic relationship quality; offspring bonding to co-parent; or co-parent past-month use of cannabis, cigarettes, or binge drinking. Findings highlight the continued need to understand how the benefits of theory-guided universal preventive interventions are sustained across the life course and how they may or may not shape family functioning for those who go on to have families and children of their own.ClinicalTrials.gov Identifier: NCT04075019.

Abstract
This study tested whether effects of a preventive intervention delivered in elementary school showed benefits for the young adult offspring of intervention recipients over 20 years later. The Raising Healthy Children (RHC) intervention, trialed in 18 public schools in Seattle, Washington, from 1980-1986 (grades 1-6), sought to build strong bonds to family and school to promote school success and avoidance of substance use and illegal behavior. Four intervention groups were constituted: full, late, parent training only, and control. Participants were followed through 2014 (age 39 years). Those who became parents were enrolled in an intergenerational study along with their oldest offspring (10 assessments between 2002 and 2018). This study includes young adult offspring (ages 18-25 years; n = 169; 52% female; 4% Asian, 25% Black, 40% multiracial, 4% Native American, 2% Native Hawaiian/Pacific Islander, 25% White, and 14% Hispanic/Latinx) of participants in the original RHC trial. Offspring outcome measures included high school noncompletion, financial functioning, alcohol misuse, cannabis misuse, cigarette use, criminal behavior, internalizing behavior, social skills, and social bonding. A global test across all young adult outcome measures showed that offspring of parents who received the full RHC intervention reported better overall functioning compared to offspring of control group parents. Analyses of individual outcomes showed that offspring of full intervention group parents reported better financial functioning than offspring of control group parents. Findings show the potential of universal preventive interventions to provide long-term benefits that reach into the next generation.

Effects of family income on brain functional connectivity in US children: associations with cognition. Mol Psychiatry 2023; 28:4195-4202.

Abstract
Higher family income (FI) is associated with larger cortical gray matter volume and improved cognitive performance in children. However, little is known about the effects of FI on brain functional and structural connectivity. This cross-sectional study investigates the effects of FI on brain connectivity and cognitive performance in 9- to 11-years old children (n = 8739) from the Adolescent Brain Cognitive Development (ABCD) study. Lower FI was associated with decreased global functional connectivity density (gFCD) in the default-mode network (DMN), inferior and superior parietal cortices and in posterior cerebellum, and increased gFCD in motor, auditory, and extrastriate visual areas, and in subcortical regions both for girls and boys. Findings demonstrated high reproducibility in Discovery and Reproducibility samples. Cognitive performance partially mediated the association between FI and DMN connectivity, whereas DMN connectivity did not mediate the association between FI and cognitive performance. In contrast, there was no significant association between FI and structural connectivity. Findings suggest that poor cognitive performance, which likely reflects multiple factors (genetic, nutritional, the level and quality of parental interactions, and educational exposure [1]), contributes to reduced DMN functional connectivity in children from low-income families. Follow-up studies are needed to help clarify if this leads to reductions in structural connectivity as these children age.

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

Abstract
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.

Abstract
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.

Abstract
Basic research studies in the past 2 decades have established that conduct problems and antisocial behavior are associated across generations within families. The Fast Track study represents a major prevention effort with children showing higher levels of conduct problems in childhood, and the Rothenberg et al. (Journal of Child Psychology and Psychiatry, 2022) study sheds light on whether this intervention has beneficial effects on the family of procreation. In this commentary, we consider the implications of the major finding that such effects were found for women but not for men. We discuss evidence that men's parenting behavior is influenced by the parenting behavior and overall risk of their women partners, and thus preventive interventions in childhood may have beneficial influences on fathers through mothers.

Abstract
The present study examines whether the Fast Track (FT) intervention, a 10-year randomized controlled trial with children at risk for conduct problems, affects family formation in adulthood, as indexed by partnerships, parenthood, and family structure, and whether the intervention effect differs across participants' gender and race/ethnicity. Participants included 891 children (intervention n = 445; control n = 446; 69% male; 51% Black, 47% White) who were recruited in kindergarten and followed to age 32 or 34 (80% participation of still-living participants), when they reported on their romantic partnerships, parenthood, and family structure. Controlling for numerous covariates that are related to family formation, intervention participants were more likely than those in the control group to be married rather than single and to have a larger number of children; the intervention and control groups did not differ on cohabitation status, age at first marriage, whether they had ever been divorced, their likelihood of being a parent, the age at which they first became a parent, the spacing of births, family structure (partnered or not, with or without children), or in whether they were residentially independent of their parents and grandparents. Intervention effects were not moderated by gender, but race/ethnicity moderated the effect of the intervention on the probability of having any children and the number of children. These findings suggest that several elements of family formation may remain unchanged by an intervention that changes many other behavioral and psychological trajectories of participants.

Abstract
BACKGROUND Many children grow up with adult alcohol misuse in the home. A clearer understanding of this exposure's long-term mental health consequences and the role of associated child maltreatment experiences and potential protective factors could guide relevant intervention strategies. OBJECTIVE To prospectively evaluate the association between living with adult alcohol misuse during childhood and major depressive disorder (MDD) during adulthood; whether child maltreatment explains the association; and whether sex, school bonding, or neighborhood bonding moderate the association.Participants and setting: This study used longitudinal data from 783 individuals followed from childhood to age 39. METHODS At grade 9, participants were asked whether they lived with adults who misused alcohol. Diagnostic assessments of MDD were conducted across three time-points during participants' thirties and participants were categorized as having met diagnostic criteria 0, 1, or 2 or more times. RESULTS Ordinal logistic regressions found that children living with adult alcohol misuse showed greater chronicity of adult MDD (OR = 1.63; 95% CI: 1.05, 2.52). There was a 49% reduction in the odds ratio and the association was no longer statistically significant when child maltreatment was included in the model (OR = 1.32; 95% CI: 0.84, 2.07). No statistically significant moderation of associations was observed. CONCLUSIONS Children exposed to adult alcohol misuse, and maltreatment often associated with this misuse, may be at risk for mental health challenges well into adulthood. Interventions that address childhood exposure to adult alcohol misuse and associated maltreatment may be important to mitigate long-term mental health challenges to exposed children.

Abstract
Young adulthood is an important developmental period for investigating the nature of violent behavior. This study examines the unique contribution of alcohol use to violence perpetration among young adults in the Australian community, after accounting for the influence of sociodemographic, early life, trait, and well-being influences. Cross-sectional, self-report data was collected from 507 young adults aged 18-20 years in the Australian general community via an online survey. Sequential logistic regressions examined the relative and independent contribution of adverse childhood experiences (ACEs), impulsivity, psychological distress, and hazardous alcohol use to past-year violent behavior. Results show one in eight young adults aged 18-20 (13%) reported at least one act of violent behavior in the past year, primarily assault perpetrated against another person. Sequential logistic regression identified that after controlling for other risk factors, the number of ACEs reported and hazardous alcohol use were independently and positively associated with increased odds of reporting violent behavior in young adulthood. These findings demonstrate that ACEs and hazardous alcohol use are important, independent correlates of violent behavior in young adults. While preventing early adversity is key for reducing violence in the community, this evidence suggests that it is also important to target proximal causes such as hazardous alcohol use. Increasing early and widespread access to evidence-based, trauma-informed violence-prevention programs targeting risk factors across multiple settings is critical for reducing harm and supporting young people into healthy adulthood.

Abstract
Background School-based drug use prevention programs have demonstrated notable potential to reduce the onset and escalation of drug use, including among youth at risk of poor outcomes such as those exposed to trauma. Researchers have found a robust relationship between intervention fidelity and participant (i.e., student) outcomes. Effective implementation of evidence-based interventions, such as the Michigan Model for HealthTM (MMH), is critical to achieving desired public health objectives. Yet, a persistent gap remains in what we know works and how to effectively translate these findings into routine practice. The objective of this study is to design and test a multi-component implementation strategy to tailor MMH to meet population needs (i.e., students exposed to trauma), and improve the population-context fit to enhance fidelity and effectiveness. Methods Using a 2-group, mixed-method randomized controlled trial design, this study will compare standard implementation versus Enhanced Replicating Effective Programs (REP) to deliver MMH. REP is a theoretically based implementation strategy that promotes evidence-based intervention (EBI) fidelity through a combination of EBI curriculum packaging, training, and as-needed technical assistance and is consistent with standard MMH implementation. Enhanced REP will tailor the intervention and training to integrate trauma-informed approaches and deploy customized implementation support (i.e., facilitation). The research will address the following specific aims: (1) design and test an implementation strategy (Enhanced REP) to deliver the MMH versus standard implementation and evaluate feasibility, acceptability, and appropriateness using mixed methods, (2) estimate the costs and cost-effectiveness of Enhanced REP to deliver MMH versus standard implementation. Discussion This research will design and test a multi-component implementation strategy focused on enhancing the fit between the intervention and population needs while maintaining fidelity to MMH core functions. We focus on the feasibility of deploying the implementation strategy bundle and costing methods and preliminary information on cost input distributions. The substantive focus on youth at heightened risk of drug use and its consequences due to trauma exposure is significant because of the public health impact of prevention. Pilot studies of implementation strategies are underutilized and can provide vital information on designing and testing effective strategies by addressing potential design and methods uncertainties and the effects of the implementation strategy on implementation and student outcomes.

Abstract
Neurocognitive development is a dynamic process over the life course and is influenced by intrauterine factors as well as later life environment. Using data from the Pune Maternal Nutrition Study from 1994 to 2008, we investigate the association of in utero, birth, and childhood conditions with offspring neurocognitive development in 686 participants of the cohort, at age 12 years. The life course exposure variables in the analysis include maternal pre-pregnancy size and nutrition during pregnancy, offspring birth measurements, nutrition and physical growth at age 12 years along with parental education and socio-economic status. We used the novel Bayesian Model Averaging (BMA) approach; which has been shown to have better predictive performance over traditional tests of associations. Our study employs eight standard neurocognitive tests that measure intelligence, working memory, visuo-conceptual and verbal learning, and decision-making/attention at 12 years of age. We control for nutritional-metabolic information based on blood measurements from the pregnant mothers and the children at 12 years of age. Our findings highlight the critical role of parental education and socio-economic background in determining child neurocognitive performance. Maternal characteristics (pre-pregnancy BMI, fasting insulin during pregnancy) and child height at 12 years were also robust predictors on the BMA. A range of early factors - such as maternal folate and ferritin concentrations during pregnancy, and child's head circumference at birth - remained important determinants of some dimensions of child's neurocognitive development, but their associations were not robust once we account for model uncertainty. Our results suggest that intrauterine influences on long- term neurocognitive outcomes may be potentially reversible by post-birth remediation. In addition to the current nutritional interventions, public health policy should also consider social interventions in children born into families with low socio-economic status to improve human capital.

Abstract
Poverty, as assessed by several socioeconomic (SES) factors, has been linked to worse cognitive performance and reduced cortical brain volumes in children. However, the relative contributions of the various SES factors on brain development and the mediating effects between cognition and brain morphometry have not been investigated. Here we used cross-sectional data from the ABCD Study to evaluate associations among various SES and demographic factors, brain morphometrics, and cognition and their reproducibility in two independent subsamples of 3892 children. Among the SES factors, family income (FI) best explained individual differences in cognitive test scores (stronger for crystallized than for fluid cognition), cortical volume (CV), and thickness (CT). Other SES factors that showed significant associations with cognition and brain morphometrics included parental education and neighborhood deprivation, but when controlling for FI, their effect sizes were negligible and their regional brain patterns were not reproducible. Mediation analyses showed that cognitive scores, which we used as surrogate markers of the children's level of cognitive stimulation, partially mediated the association of FI and CT, whereas the mediations of brain morphometrics on the association of FI and cognition were not significant. These results suggest that lack of supportive/educational stimulation in children from low-income families might drive the reduced CV and CT. Thus, strategies to enhance parental supportive stimulation and the quality of education for children in low-income families could help counteract the negative effects of poverty on children's brain development.

Abstract
Early neural development and maternal health have critical long-term effects on children's mental health and outcomes later in life. As child mental disorders continue to rise nationwide, a number of states are considering new ways of investing in the critical early childhood period to prevent later poor outcomes and reduce the burden on the mental health system. Because most state mental health authorities (SMHAs) have no dedicated mental health dollars to devote to this early, crucial period of child development, building coalitions is key to implementing prevention and promotion programming. The authors describe two issues-coalition building and contractual considerations-that should be considered as SMHAs develop these types of policies or plan new prevention and promotion initiatives. Coalition building includes establishing the structural conditions for implementing a prevention or promotion initiative, resolving workforce issues (i.e., who will carry the program out), and engaging communities and families in the effort. Contractual considerations include establishing agreed-upon measures and metrics to monitor outcomes, assigning accountability for those outcomes, and delineating realistic time frames for these investments before expecting improved outcomes. The promise of moving services upstream to support early childhood development, to prevent mental health issues from derailing children's development, and to promote children's well-being are goals that are within reach.

Applying the Social Development Model in Middle Childhood to Promote Healthy Development: Effects From Primary School Through the 30s and Across Generations. JOURNAL OF DEVELOPMENTAL AND LIFE-COURSE CRIMINOLOGY 2021; 7:66-86. [PMID: 34150470 PMCID: PMC8210839 DOI: 10.1007/s40865-020-00152-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 07/27/2020] [Accepted: 08/24/2020] [Indexed: 06/13/2023]
Abstract
PURPOSE This paper describes the origins and application of a theory, the social development model (SDM), that seeks to explain causal processes that lead to the development of prosocial and problem behaviors. The SDM was used to guide the development of a multicomponent intervention in middle childhood called Raising Healthy Children (RHC) that seeks to promote prosocial development and prevent problem behaviors. This paper reviews and integrates the tests of the SDM and the impact of RHC. While the original results of both model and intervention tests have been published elsewhere, this paper provides a comprehensive review of these tests. As such this integrative paper provides one of the few examples of the power of theory-driven developmental preventive intervention to understand impact across generations and the power of embedding controlled tests of preventive intervention within longitudinal studies to understand causal mechanisms. METHODS Application of the SDM in the RHC intervention was tested in a quasi-experimental trial nested in the Seattle Social Development Project (SSDP). SSDP is a longitudinal study of 808 students who attended 18 public schools in Seattle, WA, and whose parents consented for their participation in longitudinal research when they were in Grade 5 (77% of the eligible population in participating schools). Students assented at each survey administration and consented to longitudinal follow-up when they turned 18. Panel subjects were followed and surveyed 15 times from Grade 5 through age 39, with most completion rates above 90%. RESULTS We describe effects of the full multicomponent RHC intervention delivered in Grades 1 through 6 by comparing outcomes of those children assigned to the full RHC intervention condition to controls from middle childhood through age 39. We also report the effects of the full RHC intervention on the firstborn children of participants compared with the firstborn children of controls. CONCLUSIONS We discuss use of the theory to guide development and testing of preventive interventions and the utility of nesting intervention tests within longitudinal studies for testing both theory and interventions.

Abstract
The development of health is a cumulative, dynamic, and lifelong process responding to a variety of biological and behavioral influences, of which those in childhood are especially influential and, indeed, formative. Reflecting the balance of positive and adverse experiences during childhood, initial trajectories for future health and development emerge. Preventive pediatric care can anticipate and respond to those experiences and the personal and social circumstances in which they occur. These actions can promote better health and prevent chronic illness during adulthood. Building on the life course health development framework, ways to positively affect patterns of individual and population health practice are identified. Maximizing the opportunity to influence children's health over their lifetime will require purposeful partnerships with other entities with which children and their families interact as well as improvements in pediatric care processes. The latter includes expanding the databases that drive service (such as registries, care plans, and referrals) and adopting proactive, strengths-based, patient and family-centered, comprehensive, multidisciplinary models of care.
