Intergenerational Transmission of Parental Adverse Childhood Experiences and Children's Outcomes: A Scoping Review

Prenatal Exposure to Intimate Partner Violence and Child Developmental Outcomes: A Scoping Review Study

Pregnant women face an increased risk of intimate partner violence (IPV). In addition to the risk of violence faced by women, there is a dual concern for risk of harm to the fetus. Expanding knowledge on childbirth outcomes, other domains of children's development have been examined in recent literature. Yet, there is limited comprehensive knowledge in the area. This scoping review study, informed by ecobiodevelopmental theory, mapped evidence associating prenatal IPV exposure and children's development. We searched eight databases, including PubMed, CINAHL, and ERIC. Thirty-one empirical studies published in English that associated prenatal IPV exposure and children's development were eligible for our review. Included studies were published between 2006 and 2022, with 39% published in the most recent 5 years. Eighteen studies had sample sizes smaller than 500, and 21 were atheoretical; six failed to consider covariates. Reviewed studies showed adverse effects of prenatal IPV exposure on psychological, behavioral, physical health, and physiological outcomes, either directly or indirectly via mechanisms such as maternal behavioral health. Due to inconsistency in results and a lack of empirical evidence, however, social and cognitive outcomes were identified as needing further research to enhance our understanding of the global and domain-specific effects of prenatal IPV exposure. Prospective longitudinal studies, driven by theories of causal mechanisms, which adjust for empirically qualified confounders, will be critical to inform practice and policy to promote healthy development of prenatally IPV-exposed children. Incorporating strengths/asset-focused outcomes and examining contextual factors and sex/gender specific effects may advance the knowledge in this area.

Prevalence of Adverse Childhood Experiences in Adolescents with Special Educational and Care Needs in the Netherlands: A Case-File Study of Three Special Educational and Care Settings

To date, Adverse Childhood Experiences (ACEs) in adolescents with special educational and care needs have received little attention as an important risk factor for their behavioral, emotional, and learning problems. This study provides insight into ACE prevalence and family risk factors in three Dutch special educational and care settings for vulnerable school-aged youth. 268 adolescents (10-18 years old) with severe and persistent problems at individual and family level, from a special educational setting (setting 1; n = 59), a residential care setting (setting 2; n = 86) and an alternative educational setting (setting 3; n = 123) were included. A retrospective cross-sectional study design was used. Data were collected between 2016 and 2019 through structured case-file analysis. A substantial proportion of the adolescents in all settings experienced at least one ACE, with 69.5% in setting 1, 84.9% in setting 2 and 95.1% in setting 3. Family risk factors were relatively common, among which a limited social network in all settings (20-50%) and debts in setting 2 and 3 (25-40%). The substantial ACE prevalence underlines the need for early ACE awareness. Trauma-informed care and education are needed to adequately understand trauma-related behaviors, prevent retraumatization, and enhance learning and healthy development. Given that ACEs regarding household dysfunction and family risk factors seem to be common in adolescents with special educational and care needs, family centered approaches should be implemented as well in the interest of lifelong health and well-being for both adolescents and their families.

Do multigenerational homes moderate the intergenerational transmission of maternal adverse childhood experiences?

ABSTRACTBackground: Maternal adverse childhood experiences (ACEs) may lead to increased behavioural problems in children. However, the mediating roles of psychological distress and corporal punishment, two common mechanisms underlying the intergenerational transmission of maternal ACEs, in these relations have not been examined in Chinese samples. Multigenerational homes (MGH) are the dominate living arrangement in China; however, limited research focuses on the effects of MGHs on the intergenerational transmission of maternal ACEs.Objective: This study explored the parallel mediating effects of corporal punishment and psychological distress on the association between maternal ACEs and children's behaviour and whether MGHs can strengthen or weaken the relationship between maternal ACEs and corporal punishment or psychological distress.Participants and setting: Participants were 643 three-year-old children and their mothers (mean age of 32.85 years, SD = 3.79) from Wuhu, China.Methods: Mothers completed online questionnaires measuring ACEs, psychological distress, corporal punishment, their family structure, and children's behavioural problems. This study used a moderated mediation model.Results: The findings suggest that psychological distress and corporal punishment mediate the association between maternal ACEs and children's behavioural problems. The mediating role of corporal punishment was found depend on whether mothers and their children reside in MGHs. MGHs were not found to have a moderating role in the indirect relationship between maternal ACEs and children's behaviour problems via psychological distress.Conclusion: Our findings highlight the importance of addressing psychological distress and corporal punishment when designing interventions targeted Chinese mothers exposed to ACEs and their children, especially those living in MGHs.

The CARING study: Examining biological, behavioral, and genetic mechanisms in the intergenerational transmission of toxic stress

When children experience extreme or persistent stressors (e.g., maltreatment, housing insecurity, intimate partner violence), prolonged elevation of the stress-response system can lead to disrupted development of multiple physiological systems. This response, known as toxic stress, is associated with poor physical and mental health across the life course. Emerging evidence suggests that the effects of toxic stress may be transmitted through generations, but the biological and behavioral mechanisms that link caregivers' childhood history with the health of the children they care for remain poorly understood. The purpose of this report is to describe the research protocol for The CARING (Childhood Adversity and Resilience In the Next Generation) Study, a cross-sectional study of caregivers with children aged 3-5 years designed to (1) examine the intergenerational transmission of toxic stress and protective factors; (2) explore three hypothesized pathways of transmission: parenting, daily routines, stressors, and supports; and (3) explore the extent to which genotypic variation in candidate genes related to caregiving and stress contribute to caregivers' and children's susceptibility to the effects of early childhood experiences (i.e., gene × environment interactions). We expect that findings from this study will provide critical data needed to identify targets for precision health interventions, reduce health disparities related to toxic stress, and prevent cycles of adversity among families at risk.

Unique and shared risk factors for early childhood victimisation and polyvictimisation in a Brazilian population-based birth cohort

Background

Identifying modifiable risk factors for child victimisation and polyvictimisation (exposure to multiple types of victimisation) is critical for informing prevention efforts, yet little evidence is available in low- and middle-income countries. The authors aimed to estimate the prevalence of child victimisation and polyvictimisation, and examine unique and shared risk factors in a population-based cohort in Southern Brazil.

Methods

Lifetime child victimisation was based on maternal report when children were aged 4 years old (N∼3900) and included five types of victimisation (conventional crime, child maltreatment, peer/sibling victimisation, sexual victimisation, and witnessing/indirect victimisation) and polyvictimisation. Based on a socioecological model, possible risk factors were examined in four levels: community, maternal and family, parent, and child.

Findings

Conventional crime and peer/sibling victimisation were the most common types of victimisation (46.0 and 46.5%, respectively), followed by witnessing/indirect victimisation (27.0%), and child maltreatment (11.3%). Sexual victimisation had the lowest prevalence (1.4%). One in 10 (10.1%) children experienced polyvictimisation. In general, boys had higher victimisation rates than girls. There were few risk factors related only to specific types of victimisation (e.g., child disability was uniquely associated with child maltreatment and peer/sibling victimisation). Instead, most risk factors were shared across nearly all victimisation types and also associated with polyvictimisation. These shared risk factors were: violent neighbourhood and low social cohesion, maternal adverse childhood experiences, younger maternal age, parental antisocial behaviour, intimate partner violence against mothers, and maternal depression.

Interpretation

These findings reveal a general pattern of accumulative risk effects for different types of victimisation and polyvictimisation, rather than unique risk profiles in children aged four year Prevention efforts should target risk factors at multiple levels (e.g.,: community, maternal and family and parent) during early childhood.

A Short Adverse Experiences Measure Among Mothers of Young Children

OBJECTIVES

Screening for parental adverse childhood experiences (ACEs) in pediatric settings can be burdensome because of the questionnaire's length and sensitive nature. Rapid screening tools may help address these challenges. We evaluated a 2-item short ACE measure developed for adults in a cross-sectional sample of mothers of young children in an urban pediatric emergency department.

METHODS

From January 2011 to March 2020, we administered the ACE questionnaire in English or Spanish to 3999 biological mothers of children aged <4 years in a pediatric emergency department in Philadelphia, Pennsylvania. We assessed sensitivity and specificity of a shortened 2-item ACE measure defined as report of childhood emotional abuse and/or household substance use, using 4+ ACEs on the full questionnaire as the standard. We assessed convergent validity by comparing associations of the 2-item and standard measures with maternal, household, and child outcomes using adjusted log-binomial regression.

RESULTS

Mothers were racially and ethnically diverse (54% Latina, 35% Black non-Latina); 94% of children were publicly insured. Thirteen percent of mothers reported childhood emotional abuse and 16% childhood household substance use; 23% reported at least 1 of these and 6% both. Compared with 4+ ACEs on the full questionnaire, the 2-item measure had sensitivity 88% and specificity 90%. In adjusted models, high adversity was associated with poor maternal, household, and child outcomes.

CONCLUSIONS

A 2-item ACE measure assessing childhood emotional abuse and household substance use may be useful in pediatric settings to identify mothers who may have experienced significant child adversity and inform development, testing, or provision of comprehensive family supports.

Childhood adversity in a youth psychiatric population: prevalence and associated mental health problems

Background: Childhood adversity can have lasting negative effects on physical and mental health. This study contributes to the existing literature by describing the prevalence rates and mental health outcomes related to adverse childhood experiences (ACEs) among adolescents registered for mental health care.Methods: Participants in this cross-sectional study were youths (aged 12-18 years) who were referred to outpatient psychiatric departments in the Netherlands. Demographic information was collected from the medical records. The Child Trauma Screening Questionnaire (CTSQ) was used to examine the presence of ACEs and posttraumatic stress symptoms (PTSS). To assess mental health problems, we used the Dutch translation of the Youth Self Report. Descriptive statistics and frequencies were used to calculate prevalence rates across the various ACEs domains. ANOVA and chi-square tests were used to explore the relationship between ACEs and mental health.Results: Of the 1373 participants, 69.1% reported having experienced at least one ACE and 17.1% indicated exposure to four or more ACEs in their lives. Although there was substantial overlap among all ACE categories, the most frequently reported were bullying (49.2%), emotional abuse (17.8%), physical abuse (12.2%), and sexual abuse (10.1%). Female adolescents (72.7%) reported significantly more ACEs than their male counterparts (27.0%). Furthermore, a higher number of ACEs was associated with significantly more self-reported general mental health problems, an elevated prevalence of both mood and post-traumatic stress disorders, and a greater presence of two or more co-existing psychiatric diagnoses (comorbid psychiatric classification).Conclusions: This cross-sectional study on childhood adversity and its association with mental health showed that ACEs are highly prevalent in youth registered for mental health care. This study provides support for a graded and cumulative relationship between childhood adversity and mental health problems.

Intergenerational cascade processes from parental childhood adversity to child emotional and behavioral problems

BACKGROUND

Parental adverse childhood experiences (ACEs) may transmit to the next generation and influence children's emotional and behavioral problems. Relatively little evidence exists on the underlying pathways of this intergenerational transmission at the family- and individual-level.

OBJECTIVE

This study examined the intergenerational cascade processes of parental ACEs on children's emotional and behavioral problems via family cohesion, children's ACEs, and children's self-control.

PARTICIPANTS AND SETTING

283 children (52 % male, Mage = 10.47 years) and their parents (61.1 % mothers, Mage = 38.62 years) were recruited for a 2-month longitudinal study with surveys administered at three time points.

METHOD

Mediation models examined the intergenerational effects of parental ACEs (T1/T3) and family cohesion (T1) as reported by parents, and children's ACEs (T1) and children's self-control (T2) as reported by children, on children's internalizing and externalizing problems (T3) as reported by parents.

RESULTS

Family cohesion, children's ACEs, and children's self-control sequentially mediated the link between parental ACEs and children's externalizing problems (indirect effect = 0.004, 95 % CI [0.001, 0.014]). Parental ACEs were directly linked with children's internalizing problems (β = 0.191, SE = 0.075, p = .011).

CONCLUSIONS

Findings demonstrated intergenerational cascades of distal and proximal risk processes from parental ACEs to children's behavioral problems. These findings have implications for future interventions on children's externalizing problems that aim at improving family cohesion and children's self-control for families exposed to childhood adversity.

A psychometric analysis of the Early Trauma Inventory-Short Form in Colombia: CTT and Rasch model

BACKGROUND

Potential childhood traumatic experiences increase risk for mental and physical health disorders and their precise assessment can help to promote health prevention and promotion strategies for countries with limited data and measurement strategies like Colombia.

OBJECTIVE

The goal of the present study is to strengthen evidence for the validity of scores from an adapted version of the Early Trauma Inventory self report-short form (ETI-SF) using Item Response Theory and by assessing factorial invariance across gender and education level.

PARTICIPANTS AND SETTING

The study assessed a total of 1909 Colombian participants (66.16 % women, 32.16 % men, 1.68 % other gender; age range 18-72 years old).

METHODS

Participants answered the ETI-SF via a web-based sampling strategy.

RESULTS

The total scores of the scale showed good reliability coefficients (α = 0.81 and ω = 0.60). A specific analysis for the subscales showed good reliability for the emotional, physical, and sexual trauma subscales (αs and ωs >0.64), while general trauma showed lower than accepted reliability values (α =0.56 and ω = 0.37). Most of the individual items of the scale showed good calibration. The factorial invariance analysis suggests the possibility of some gender and educational differences.

CONCLUSIONS

The study confirms particularly high rates of potential childhood traumatic experiences in Colombia and complement data for specific trauma types. Overall, the ETI-SF is confirmed as useful for Colombia, which highlights this scale as a good tool to use for public health assessment. Future research can continue the integration of diverse methods for estimating the quality of the scale.

The pernicious role of stress on intergenerational continuity of psychopathology

Development and Psychopathology has been a premier resource for understanding stressful childhood experiences and the intergenerational continuity of psychopathology. Building on that tradition, we examined the unique and joint influences of maternal stress on children's effortful control (age 7) and externalizing behavior (age 11) as transmitted via genetics, the prenatal environment, and the postnatal environment. The sample included N = 561 adopted children and their biological and adoptive parents. Path models identified a direct effect of biological mother life stress on children's effortful control (β = -.08) and an indirect effect of her life stress on child externalizing behavior via effortful control (β = .52), but no main or indirect effects of biological parent psychopathology, prenatal stress, or adoptive mother adverse childhood experiences (ACES). Adoptive mother ACES amplified the association between biological mother life stress and child effortful control (β = -.08), externalizing behavior (β = 1.41), and the indirect effect via effortful control, strengthening associations when adoptive mothers reported average or high ACES during their own childhoods. Results suggest that novel study designs are needed to enhance the understanding of how life stress gets "under the skin" to affect psychopathology in the offspring of adults who have experienced stress.

The effect of parental regulatory focus on the loneliness stigma of college children

BACKGROUND

The present study aimed to examine the relationship between regulatory focus and loneliness stigma, as well as the intergenerational transmission of the two. Specifically, the study analyzed the effects of fathers' and mothers' regulatory focus on their own and their spouses' stigma of loneliness. In addition, a mediation model was constructed to explore how parents' regulatory focus influences their children's stigma of loneliness and the potential mediating mechanisms involved.

METHODS

Questionnaires were distributed to 470 college students and their parents, employing the Regulatory Focus Questionnaire (RFQ) and the Stigma of Loneliness Scale (SLS) to collect data.

RESULTS

The analysis of intergenerational transmission effects revealed that parents' regulatory focus and loneliness stigma significantly and positively predicted children's regulatory focus and loneliness stigma, respectively. The Actor-Partner Interdependence Model (APIM) elucidated that both fathers' and mothers' promotion focus exerted significant influence on both actor and partner's loneliness stigma. Furthermore, the mediation model analysis indicated that parents' loneliness stigma, along with children's regulatory focus operate as mediators in the influence of parental regulatory focus on loneliness stigma of their college-aged offspring.

CONCLUSIONS

From a familial context, this study, investigated the association between regulatory focus and loneliness stigma, along with the mediating roles within parent-child groups and couples. The findings enhanced our comprehension of the interrelation between regulatory focus and loneliness stigma, underpinned by empirical evidence.

A role for adverse childhood experiences and depression in preeclampsia

Introduction

Adverse childhood experiences (ACEs) are a measure of childhood adversity and are associated with life-long morbidity. The impacts of ACEs on peripartum health including preeclampsia, a common and dangerous hypertensive disorder of pregnancy, remain unclear, however. Therefore, we aimed to determine ACE association with peripartum psychiatric health and prevalence of preeclampsia using a case-control design.

Methods

Clinical data were aggregated and validated using a large, intergenerational knowledgebase developed at our institution. Depression symptoms were measured by standard clinical screeners: the Patient Health Questionnaire-9 (PHQ-9) and the Edinburgh Postnatal Depression Scale (EPDS). ACEs were assessed via survey. Scores were compared between participants with (N = 32) and without (N = 46) prior preeclampsia.

Results

Participants with ACE scores ≥4 had significantly greater odds of preeclampsia than those with scores ≤ 3 (adjusted odds ratio = 6.71, 95% confidence interval:1.13-40.00; p = 0.037). Subsequent speculative analyses revealed that increased odds of preeclampsia may be driven by increased childhood abuse and neglect dimensions of the ACE score. PHQ-9 scores (3.73 vs. 1.86, p = 0.03), EPDS scores (6.38 vs. 3.71, p = 0.01), and the incidence of depression (37.5% vs. 23.9%, p = 0.05) were significantly higher in participants with a history of preeclampsia versus controls.

Conclusions

Childhood sets the stage for life-long health. Our findings suggest that ACEs may be a risk factor for preeclampsia and depression, uniting the developmental origins of psychiatric and obstetric risk.

Maternal Adverse Childhood Experiences and Young Adult Latino Children's Mental Health

INTRODUCTION

Maternal adverse childhood experiences have been linked to a variety of negative health outcomes in young children; however, young adults and, specifically, young adult Latinos have been vastly understudied. This study investigates the intergenerational pathway between maternal adverse childhood experiences and behavioral health outcomes of their young adult children, as mediated through young adults' own adverse childhood experiences and maternal depression.

METHODS

Structural equation modeling was used to analyze data (in 2023) from mothers and their young adult children (n=398 dyads) enrolled in the Center for the Health Assessment of Mothers and Children of Salinas cohort, a primarily Latino agricultural sample. Maternal and young adult adverse childhood experiences were self-reported retrospectively during a visit at the age of 18 years (2018-2020). Young adult- and maternal-reported internalizing and maternal-reported externalizing behaviors were assessed at the age of 18 years with the Behavior Assessment for Children, second edition. Maternal depression was assessed during a visit at the age of 9 years (2010-2012) using the Center for Epidemiologic Studies Depression Scale.

RESULTS

Maternal and young adult adverse childhood experiences were weakly but statistically significantly correlated (r=0.22). Maternal adverse childhood experiences were statistically significantly associated with maternal-reported youth internalizing symptoms (β=0.29; 95% CI=0.19, 0.38; p<0.001) and externalizing symptoms (β=0.24; 95% CI=0.14, 0.33; p<0.001) and marginally associated with youth-reported internalizing symptoms (β=0.08; 95% CI= -0.02, 0.18; p=0.13). Youth adverse childhood experiences and maternal depressive symptomatology mediated the associations between maternal adverse childhood experiences and young adult outcomes.

CONCLUSIONS

Findings demonstrate the potential impacts of adversity across generations in Latino immigrant families, an understudied population. Understanding the mechanisms and factors associated with these pathways may lead to strategies that prevent poor mental health outcomes in young adults.

Intergenerational transmission of parent adverse childhood experiences to child outcomes: A systematic review and meta-analysis

OBJECTIVE

The current meta-analytic review provides a comprehensive synthesis of studies examining parent exposure to ACEs and the developmental and mental health outcomes of their children.

PARTICIPANTS AND SETTING

Eligible studies up to August 2021 were identified through comprehensive database searches in PsycINFO, MEDLINE, and Embase. Studies that were included examined the intergenerational effects of parent ACEs on child development (i.e., cognitive, language, motor, social difficulties, and early social-emotional development) or mental health (i.e., internalizing problems, externalizing problems) outcomes.

METHODS

Data were extracted by two coders using a standardized extraction protocol. A multi-level meta-analytic approach was used to derive pooled effect sizes and test for moderators.

RESULTS

A total of 52 studies were included in the meta-analysis. Parent ACEs were positively associated with child mental health problems (r=0.17, 95% CI [0.12, 0.21], p<.001), child externalizing difficulties (r=0.20, 95% CI [0.15, 0.26], p<.001), and child internalizing difficulties (r=0.17, 95% CI [0.11, 0.22], p<.001). There were no significant sociodemographic (i.e., child age, parent age, income level, child sex, or racial/ethnic minority status) or methodological (i.e., study type or quality) moderators of these associations. Preliminary evidence suggests that parent ACEs were not associated with offspring developmental outcomes, such as cognitive or language skills.

CONCLUSIONS

Results suggest that parent ACEs are associated with some, but not all child outcomes. Additional research focused on the mechanisms of transmission are needed to inform policies and practices related to the intergenerational transmission of ACEs.

Parents' Adverse and Positive Childhood Experiences and Offspring Involvement With the Criminal Legal System

Importance

Intergenerational cycles of adversity likely increase one's risk of criminal legal system involvement, yet associations with potential contributors, such as parents' adverse childhood experiences (ACEs) and positive childhood experiences (PCEs), have not been explored.

Objective

To investigate the association of parents' ACEs and PCEs with their adult children's involvement in US legal systems, from arrest to conviction.

Design, Setting, and Participants

The study team analyzed data from the Panel Study of Income Dynamics (PSID), a nationally representative cohort study of families in the US. PSID-2013 survey data were merged with the 2014 PSID Childhood Retrospective Circumstances Study (CRCS), collected May 2014 to January 2015, which asked adults aged 18 to 97 years to retrospectively report on their childhood experiences. Parents and their adult children were linked in the data set. Data were analyzed from October 2022 to September 2023.

Main Outcomes and Measures

The child arrest outcome was regressed on parents' ACE and PCE scores using logistic regression models. In addition, multinomial logistic regression models were used to assess the associations of parents' ACE and PCE scores with the number of times their child was arrested and convicted.

Results

Of 12 985 eligible individuals, 8072 completed the CRCS. Among CRCS participants, there were 1854 eligible parent-child dyads (ie, parents and their adult children) that formed the analytic sample. The mean (SD) age of offspring at the time of CRCS completion was 38.5 (10.9) years, and 1076 offspring (51.3%) were female. Having 4 or more parental ACEs was associated with 1.91-fold (95% CI, 1.14-3.22) higher adjusted odds of arrest before age 26 and 3.22-fold (95% CI, 1.62-6.40) higher adjusted odds of conviction before age 26 years, compared with children of parents without ACEs. These associations persisted after controlling for parental PCEs.

Conclusions and Relevance

In this nationally representative study, children of parents with higher ACEs were at greater risk of arrest during adolescence and young adulthood, even after controlling for parents' PCEs. Addressing and preventing childhood adversity through multigenerational life course approaches may help disrupt intergenerational pathways to the criminal legal system.

Infant epigenetic aging moderates the link between Black maternal childhood trauma and offspring symptoms of psychopathology

Although offspring of women exposed to childhood trauma exhibit elevated rates of psychopathology, many children demonstrate resilience to these intergenerational impacts. Among the variety of factors that likely contribute to resilience, epigenetic processes have been suggested to play an important role. The current study used a prospective design to test the novel hypothesis that offspring epigenetic aging - a measure of methylation differences that are associated with infant health outcomes - moderates the relationship between maternal exposure to childhood adversity and offspring symptomatology. Maternal childhood adversity was self-reported during pregnancy via the ACEs survey and the CTQ, which assessed total childhood trauma as well as maltreatment subtypes (i.e., emotional, physical, and sexual abuse). Offspring blood samples were collected at or shortly after birth and assayed on a DNA methylation microarray, and offspring symptomatology was assessed with the CBCL/1.5-5 when offspring were 2-4 years old. Results indicated that maternal childhood trauma, particularly sexual abuse, was predictive of offspring symptoms (ps = 0.003-0.03). However, the associations between maternal sexual abuse and offspring symptomatology were significantly attenuated in offspring with accelerated epigenetic aging. These findings further our understanding of how epigenetic processes may contribute to and attenuate the intergenerational link between stress and psychopathology.

Indigenous Cultural Identity Protects Against Intergenerational Transmission of ACEs Among Indigenous Caregivers and Their Children

A large body of empirical research has demonstrated that caregiver adverse childhood experiences (ACEs) predict ACEs in one's child, a phenomenon known as the intergenerational transmission of ACEs. Little of this empirical research, however, has focused specifically on Indigenous peoples despite a growing body of theoretical literature and the wisdom of Elders and Traditional Knowledge Keepers that speaks to the presence of this phenomenon within Indigenous communities as well as the protective role of Indigenous cultural identity in preventing the intergenerational transmission of ACEs. The purpose of the current study was to conduct an empirical evaluation of this hypothesis, specifically that Indigenous cultural identity and social support protects against the intergenerational transmission of ACEs among Indigenous peoples and their children in the USA. Participants were 106 Indigenous women caregivers of children ages 10 to 14 in South Dakota who completed surveys. Results showed that Indigenous cultural identity moderated the association between caregiver ACEs and child ACEs. At high levels of cultural identity, there was no association between caregiver ACEs and child ACEs. At low levels of Indigenous cultural identity, however, there was a strong and positive relationship between caregiver ACEs and child ACEs. Social support did not moderate the association between caregiver ACEs and child ACEs. These findings underscore the need for initiatives that enhance Indigenous cultural identity and social support among Indigenous caregivers to prevent the intergenerational transmission of ACEs.

Intergenerational Continuity of Childhood Adversity and Its Underlying Mechanisms Among Teen Mothers and Their Offspring

The present study investigates how parenting stress mediates the intergenerational continuity of childhood adversity in teenage mothers. Childhood adversity experiences of caregivers significantly affect their offspring's exposure to childhood adversity. However, little is known about the mechanisms linking childhood adversity across generations. The study measures how parental distress and parent-child dysfunctional interaction mediate the association between teen mothers' childhood adversity and their offspring's adversity, measuring when the offspring reached 11.5 years of age. The results revealed that parental distress, but not parent-child dysfunctional interaction, mediated the association between teen mothers' child abuse and their offspring's household dysfunction. This suggests that parental distress may be a crucial intervention target to prevent the intergenerational continuity of childhood adversity. The findings imply that efforts to prevent the intergenerational continuity of childhood adversity may be more successful if the public and professionals have a broader understanding of the associations between early adversity and parenting contexts. In conclusion, the study shed light on the potential mechanisms underlying the intergenerational continuity of childhood adversity and highlights the importance of targeting parenting stress, specifically parental distress, as an intervention strategy to prevent the perpetuation of childhood adversity across generations.

The Feasibility of the Adverse Childhood Experiences Questionnaire among Women in Danish Antenatal Care: A Mixed-Methods Study

A traumatic upbringing increases the risks of antenatal health problems, unfavourable pregnancy outcomes, and mental disorders. Such childhood experiences may affect women's pa-renting skills and the social-emotional functioning of their children. Research on screening for adverse childhood experiences in antenatal care is limited. The objective of this study was to explore pregnant women's attitudes towards and experiences of an adverse childhood experiences questionnaire, and to assess the relevance of the questionnaire among a population of pregnant women referred to antenatal care levels one and two, targeting women who are generally not perceived to be vulnerable. Data were collected at three maternity wards and consisted of quantitative data on 1352 women's adverse childhood experience scores, structured observations of 18 midwifery visits, and in-depth interviews with 15 pregnant women. Quantitative data were analysed by descriptive statistics, and qualitative data were analysed using systematic text condensation. The qualitative analysis revealed two main categories: "Being screened for childhood adversities" and "Having adverse childhood experiences". In the study population, the prevalence of adverse childhood experiences was high. The women assessed the adverse childhood experiences questionnaire to be a relevant and acceptable screening method. Furthermore, women's perceptions of their relationship with their midwife greatly impacted their attitudes towards and experiences of the questionnaire.

Intergenerational and early life associations of the gut microbiome and stress-related symptomatology among Black American mothers and children

Recent evidence suggests that maternal childhood adversity may have an intergenerational impact, with children of adversity-exposed mothers exhibiting elevated symptoms of psychopathology. At the same time, many children demonstrate resilience to these intergenerational effects. Among the variety of factors that likely contribute to resilience, the composition of the gut microbiome may play a role in buffering the negative impacts of trauma and stress. The current prospective cohort study tested the novel hypothesis that offspring gut microbiome composition is a potential moderator in the relationship between maternal exposure to childhood adversity and offspring symptomatology (i.e., internalizing, externalizing, and posttraumatic stress symptoms). Maternal childhood adversity was self-reported during pregnancy via the Childhood Trauma Questionnaire and Adverse Childhood Experiences (ACEs) survey, and offspring symptomatology was assessed with the Child Behavior Checklist/1.5-5 when offspring were 2-4 years old. Offspring fecal samples were collected between these timepoints (i.e., during 6- to 24-month follow-up visits) for microbiome sequencing. Results indicated that maternal ACEs and the relative abundances of Bifidobacterium, Lactobacillus, and Prevotella were associated with offspring symptomatology. However, there was little evidence that microbial abundance moderated the association between maternal adversity and offspring symptoms. Overall, these findings further our understanding of how the gut microbiome associates with psychopathology, and informs future studies aimed at targeting modifiable factors that may buffer the intergenerational effects of childhood adversity.

Perception of School Violence: Indicators of Normalization in Mapuche and Non-Mapuche Students

The current social and political scenario in Chile has opened up the debate on two centuries of usurpation and discrimination towards the Mapuche people. Educational centers are not oblivious to the social exclusion faced by indigenous children and young people, and this forms part of the phenomenon of school violence. This study explores the differences in perception between Mapuche and non-Mapuche students regarding school violence. The issue is the lack of knowledge regarding cultural variations in the perception of school violence in spaces of social and cultural diversity in the Mapuche context. This study describes the characteristics of school violence perceived by students in relation to differences based on ancestry and characterizes the variations in perception. A total of 1404 students participated from urban schools in the city of Temuco, Chile, aged 10 to 13 (M = 11.4; SD = 1.1) who completed the CENVI questionnaire. The confirmatory factor analysis (CFA) of the total sample and categories provides indexes that fit the proposed model. The omega coefficients provide internal reliability guarantees. This study tests configural, metric and scalar invariance for all the categories explored, and statistically significant differences are found between Mapuche and non-Mapuche students in the perception of physical and verbal violence, where the Mapuche student perceives more violence. Results are discussed based on existing research on education in spaces of social and cultural diversity in the Mapuche context, with research into elements that can help explain the findings.
