Maternal depression in the intergenerational transmission of childhood maltreatment and its sequelae: Testing postpartum effects in a longitudinal birth cohort

The future of intergenerational transmission research: A prospective, three-generation approach

Dr. Dante Cicchetti's pioneering theory and research on developmental psychopathology have been fundamental to the proliferation of research on intergenerational transmission over the last 40 years. In part due to this foundation, much has been learned about continuities and discontinuities in child maltreatment, attachment, parenting, and psychopathology across generations. Looking towards the future, we propose that this field stands to benefit from a prospective, three-generation approach. Specifically, following established prospective, longitudinal cohorts of children over their transition to parenting the next generation will afford the opportunity to investigate the developmental origins of intergenerational transmission. This approach also can address key outstanding questions and methodological limitations in the extant literature related to the confounding of retrospective and prospective measures; examination of mediators and moderators; and investigation of the roles of biology, environment, and their interplay. After considering these advantages, we offer several considerations and recommendations for future research, many of which are broadly applicable to the study of two or more generations. We hope that this discussion will inspire the leveraging of existing prospective cohorts to carry forward Dr. Cicchetti's remarkable contributions, with the ultimate aim to inform the development of preventions and interventions that disrupt deleterious intergenerational cycles.

The Prevalence, Predictors, and Health Consequences of Disagreement in Reports of Child Maltreatment Exposure

The purpose of this study was to examine the prevalence, predictors, and consequences of disagreement between prospective caregiver and retrospective child reports of childhood physical and emotional maltreatment. The design was a secondary analysis of data from the Avon Longitudinal Study of Parents and Children, a three-decade long UK-based birth cohort. Prospective caregiver reports were in poor to fair agreement with retrospective child reports for physical and emotional maltreatment exposure, with caregivers tending to underreport exposure. Disagreement between reporters was associated with increased risk of depressive symptoms and substance use severity, but decreased risk for mental health diagnoses. Screening measures of childhood maltreatment exposure should take caution against using measures from different reporters interchangeably (i.e., from mother versus child). Disagreement in reports may indicate unmet need for mental health evaluation.

Trauma in the lives of parents experiencing severe perinatal mental illness

Background

The perinatal period is a time of 'high risk' for new and recurrent episodes of mental illness with 0.1-0.2% of birthing parents requiring admission to specialist mental health units in the months after birth. The prevalence and role of trauma in the lives of birthing parents (most commonly mothers) experiencing severe perinatal mental illness is not well known.

Method

In a new perinatal mental health unit in Sydney Australia, a retrospective audit of trauma prevalence was undertaken using patient completed questionnaires and electronic medical record data. Descriptive analysis was undertaken.

Results

Prevalence of trauma in the lives of mothers with severe mental illness was found to be higher than that reported in general or community mental health settings, with 76% of mothers reporting lifetime trauma exposure and 24% meeting criteria for complex PTSD. The majority reported trauma experiences likely to impact attachment and also reported difficulties in responding to their infants' cues and needs.

Discussion

The findings suggest a need for more research, awareness, and consideration of the role of trauma in experiences of perinatal mental illness, with implications for developing trauma informed models for responding to parental mental illness.

Long-term consequences of childhood emotional abuse in mothers on parental load and child mental health

BACKGROUND

Childhood emotional maltreatment can be associated with long-term consequences on mental health. In addition, transgenerational transmission of adverse childhood experiences to the next generation can occur and thus have an impact on the mental health of one's own children.

OBJECTIVE

The purpose of this study was to examine the role of stress on the association between childhood emotional maltreatment and parental load what is referred to in this study as limitations in parental functioning that affect the resources available to parents to cope with the demands of raising, caring for, and providing for their child. Furthermore the effect of parental load on the mental health of one's own children will be examined.

PARTICIPANTS AND SETTING

N = 237 mother-child dyads (age mother M = 33.76, SD = 4.07 years; age child M = 11.91 months, SD = 0.89 months) from a longitudinal cohort study were examined at two different measuring points.

METHODS

Emotional abuse, perceived stress, parental load and child mental health were assessed using self and external report questionnaires.

RESULTS

The calculation of a mediation showed that the association of emotional abuse and parental load was completely mediated by perceived stress (indirect effect ab = 0.44, 95 %-CI[0.17, 0.78]). In addition, effects of parental load on the child's mental health (β = 0.13, 95%CI [0.07;0.20]), mainly hyperactivity (β = 0.06, 95%CI [0.03;0.11]) and prosocial behavior (β = -0.04, 95%CI [-0.07; -0.01]), were evident.

CONCLUSIONS

The results of this study provide evidence that the mental health of children can be influenced in the long term by increased parental load.

Mother-to-infant bonding difficulties are associated with future maternal depression and child-maltreatment behaviors: A Japanese nationwide longitudinal study

BACKGROUND

Mother-to-infant bonding difficulties (MIBD) are considered risk factors for postpartum depression and child-maltreatment behaviors. However, few longitudinal studies have examined this hypothesis. This study aims to explore the relationship between MIBD and subsequent maternal depression and child-maltreatment behaviors using longitudinal data from a 2021 Japanese nationwide survey.

METHODS

We studied 658 first-time mothers who had given birth within the past year and had not reported postpartum depression or child-maltreatment behaviors at baseline. The Japanese version of Mother-to-Infant Bonding Scale (MIBS) was used to measure MIBD. Subjects were monitored for six months and subsequently completed the Edinburgh Postnatal Depression Scale and responded to inquiries about child-maltreatment behaviors.

RESULTS

After adjusting for covariates, MIBD was associated with higher odds of maternal depression (OR=1.737, 95 % CI [1.078, 2.797]) and child-maltreatment behaviors (OR=2.040, 95 % CI [1.401, 2.970]) six months later. Further analysis indicated that MIBD was particularly associated with a heightened risk of emotional abuse (OR=2.172, 95 % CI [1.486, 3.176]). Sensitivity analysis confirmed these findings through multiple approaches, such as applying inverse probability weighting to mitigate selection bias, using an alternative MIBS cutoff score of 5, and adopting a time-varying model to account for the dynamic nature of depressive symptoms and child-maltreatment behaviors.

CONCLUSION

Proactive screening for MIBD could serve as a valuable tool in the early detection of maternal depression and potential child-maltreatment behaviors.

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.

Maternal postnatal depressive symptoms and early achievement of developmental milestones in infants and young children: A meta-analysis

Screening for social determinants of health, including maternal depression, is a recommended pediatric practice. However, the magnitude of association between maternal and child screening tools remains to be determined. The current study evaluated the association between maternal postnatal depressive symptoms and child developmental milestones, as well as moderators of these associations. A comprehensive search strategy was carried out in four databases (MEDLINE, EMBASE, APA PsycINFO, and Cochrane Central Register of Controlled Trials) from database inception to September 2022. Studies that examine postnatal depressive symptoms and associations with infant and early child (<6 years) achievement of developmental milestones were included. Data were extracted by two independent coders and a random-effects meta-analysis was used to estimate pooled effect sizes and test for moderators. A total of 38 non-overlapping studies (95,897 participants), all focused on maternal postnatal depression, met inclusion criteria. The pooled effect size for the association between postnatal depressive symptoms and early achievement of infant and child developmental milestones (N = 38; r = -.12; 95% CI = -.18, -.06) was small in magnitude. Child age at maternal depression measurement was a moderator, whereby effect sizes became greater for older children. Despite small effects, maternal postnatal depressive symptoms should be included in screening during routine well-child visits to enhance child development outcomes.

Fathers' mental Ill-health and child maltreatment: A systematic review of the literature

Background

Parental mental ill-health is often described as a risk factor for child maltreatment. Yet the literature commonly foregrounds maternal mental ill-health. To obtain a more complete picture, it is crucial to also understand the associations between fathers' mental health and child maltreatment.

Aim

To provide a narrative synthesis of evidence about the relationship between fathers' mental health and child maltreatment.

Method

Four electronic databases were searched, identifying 5479 citations. 151 studies were brought to full-text review. 37 were included in the study.

Results

Studies revealed mixed evidence for associations between forms of paternal mental ill health and child maltreatment, with stronger evidence for paternal depression and weak or no evidence for PTSD and anxiety. Many confounding factors were identified across the papers.

Discussion

The small number and limited range of good quality studies indicate the need to correct the relative invisibility of fathers within research about mental health and child maltreatment. At present, the available evidence is not sufficient to draw firm conclusions about the association between fathers' mental health and child maltreatment or appropriate policy and practice responses.

The Role of Psychopathology and Emotion Regulation in the Intergenerational Transmission of Childhood Abuse: A Family Study

Previous studies have shown that parents with a history of childhood abuse are at increased risk of perpetrating child abuse. To break the cycle of childhood abuse we need to better understand the mechanisms that play a role. In a cross-sectional extended family design including three generations (N = 250, 59% female), we examined the possible mediating role of parental psychopathology and emotion regulation in the association between a history of childhood abuse and perpetrating child abuse. Parents' own history of childhood abuse was associated with perpetrating abuse toward their children, and externalizing (but not internalizing) problems partially mediated this association statistically. Implicit and explicit emotion regulation were not associated with experienced or perpetrated abuse. Findings did not differ across fathers and mothers. Findings underline the importance of (early) treatment of externalizing problems in parents with a history of childhood abuse, to possibly prevent the transmission of child abuse.

Examining the relationship between maternal childhood abuse history and mother-infant bonding: The mediating roles of postpartum depression and maternal self-efficacy

BACKGROUND

The detrimental effects of childhood abuse on long-term outcomes are well-known, however few studies have examined these effects in the context of postpartum psychopathology, maternal self-efficacy, and mother-infant bonding quality.

OBJECTIVE

This study aimed to examine the relationship between a maternal childhood abuse experience (i.e., physical, psychological, and sexual) and mother-infant bonding disturbances, and whether this relationship was mediated by postnatal depression symptomatology and maternal self-efficacy.

METHOD

A sample of 191 postpartum women (Mage = 32.88, SD = 4.20) recruited online from the general population completed self-report measures of the constructs of interest.

RESULTS

Postnatal depression symptomatology and maternal self-efficacy were found to fully mediate the relationship between psychological child abuse experience and mother-infant bonding disturbances (β = 0.06, SE = 0.03, 95% CI: 0.01, 0.12). Postnatal depression symptomatology (but not maternal self-efficacy) was an independent mediator between psychological child abuse experience and mother-infant bonding (β = 0.07, SE = 0.03, 95 % CI: 0.01, 0.13). After inclusion of other abuse types as covariates in the analyses, the findings for maternal child physical abuse attenuated to non-significance. Child sexual abuse was not associated with the mediating or outcome variables, highlighting the issue of disclosure despite the anonymous online environment.

CONCLUSION

This study highlights the negative impact of psychological childhood abuse experience on the quality of the mother-infant bond during the postpartum period and potential pathways that underlie this relationship. This study also draws attention to the need to recognize comorbidity of abuse types in research.

Maternal depression trajectories in childhood, subsequent maltreatment, and adolescent emotion regulation and self-esteem: the 2004 Pelotas birth cohort

This study aimed to examine the impact of maternal depressive symptoms trajectories on 15-year-old adolescents' self-esteem and emotion regulation and test the mediating role of child maltreatment in this association. The 2004 Pelotas Birth Cohort is an ongoing cohort study originally comprised of 4231 live births in a southern Brazilian city. We examined a subsample of 1949 adolescents at age 15 years. Maternal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale. Trajectories of maternal depression from 3 months until the 11-year follow-up were calculated using a group-based modeling approach. Child maltreatment at age 11 years was measured using the parent-report version of the Parent-Child Conflict Tactics Scale. Adolescent outcomes at age 15 years were assessed by the self-report version of the Rosenberg Self-esteem Scale and the Emotion Regulation Index for Children and Adolescents. Path model analysis was conducted using a structural equation modeling framework in Mplus software. All maternal depression trajectories were negatively associated with offspring self-esteem and emotion regulation compared to the reference group (low depression trajectory). There was a significant indirect effect of maternal depression trajectories on emotion regulation mediated via child maltreatment. No evidence of moderation by sex was found for any pathway. The effects of maternal depression on adolescents' emotion regulation are partly mediated by child maltreatment at age 11.

Associations of COVID-19 Stressors and Postpartum Depression and Anxiety Symptoms in New Mothers

BACKGROUND AND OBJECTIVES

Early reports during the COVID-19 pandemic showed pregnant and postpartum women have increased rates of anxiety and depression. We hypothesized that exposure to more COVID-19-related events (e.g., stay-at-home orders, school closures, work layoffs, family members ill with COVID-19; Event Exposure), greater perceived impact of COVID-19 events on the family (Family Impact), and less social support would be associated with more anxiety and depression symptoms among first-time mothers.

METHODS

We interviewed 125 first-time mothers of infants under 3 months of age from four pediatric primary care offices (June 2020 - February 2021) to assess COVID-19 experiences, anxiety and depression symptoms, and social support. Hierarchical linear regression evaluated relations between COVID-19 Event Exposure, COVID-19 Family Impact, and social support on maternal anxiety and depression symptoms.

RESULTS

COVID-19 Event Exposure was not associated with depression or anxiety symptom scores. However, greater COVID-19 Family Impact was related to increased maternal depression and anxiety symptoms when controlling for COVID-19 Event Exposure. Reduced social support predicted higher depression symptom scores, but not anxiety symptom scores, when accounting for other variables.

CONCLUSION

The number of COVID-19-related events experienced by first-time mothers did not predict anxiety or depression symptoms. However, greater perceived impact of COVID-19 on their family was associated with higher symptoms of anxiety and depression in these mothers. Pediatricians can promote resilience strategies to help new mothers adapt during the COVID-19 pandemic to help decrease anxiety and depression symptoms.

Depression in the next generation is related with maternal behaviors: A cross-comparison by alternating rat's mother care

This study investigated the potential impacts of depressive rats' maternal behavior as an early life stress on the outcome of offspring as an adulthood. Offspring from the same mother were divided into two groups, half of them were fostered or remained by a depressive mother, and the other half remained or fostered by a control mother, respectively. The results showed that offspring fostered by depressive mothers presented significant depressive behaviors. Meanwhile, depressive mothers engaged in more grooming during the light cycle, but less off-the-pup behavior during the dark phase. In conclusion, offspring exposed to a postnatal depressive maternal environment developed a depressive-like behavior. Contrarily, postpartum maternal behaviors play an essential role, which might determine the outcome of the next generation. Furthermore, the appropriate timing of postpartum maternal caring sequences, which might eliminate prenatal stressful influences, was recognized and might be a promising approach for reducing children's predisposition to mental disorders in their life time.

Maternal history of maltreatment and offspring's emotional and behavioral problems in adolescence: Do family factors contribute to the intergenerational risk transmission?

BACKGROUND

A history of childhood maltreatment often has a negative and long-lasting impact across different domains in life. A childhood maltreatment experience in parents may even affect the next generation. So far, the effects of family factors have been considered in the intergenerational transmission of adversity across the childhood years, but whether the effects remain until adolescence is less clear.

OBJECTIVE

Using data from a large population-based study in the Netherlands, including both mother and child reports, we examined whether maternal childhood maltreatment history is associated with increased mental health problems in offspring and the role of family functioning and harsh parenting as a potential pathway.

PARTICIPANTS

4912 adolescents (aged 13 years) and their mothers were recruited in the Generation R study.

METHODS

Mothers reported childhood maltreatment experiences using the Childhood Trauma Questionnaire (CTQ), and adolescents reported on their mental health using the Youth Self Report (YSR). Structural equation modeling (SEM) was used to test the association of maternal childhood maltreatment on mental health problems in offspring and family functioning and harsh parenting as mechanisms to explain this association.

RESULTS

Adolescents of mothers with a history of maltreatment had greater internalizing (β = 0.07, p < .01) and externalizing problems (β = 0.08, p < .01). Moreover, we found an indirect effect via family functioning over time and harsh parenting at ages 3 and 8 years which mediated this association.

CONCLUSION

We concluded an intergenerational effect of maternal childhood maltreatment on adolescents internalizing and externalizing problems. The findings might enable earlier intervention within the family context to mitigate the consequences of maternal childhood maltreatment.

Maternal Childhood Maltreatment History and Child Behavior Problems: Developmental Patterns and Mediation via Maternal Depressive Symptoms and Parenting Behavior

Maternal exposure to childhood maltreatment (CM) is associated with offspring behavioral problems; however, little work has examined these associations longitudinally across child development. This study examined the effects of maternal history of CM on trajectories of child internalizing and externalizing behavior measured from toddlerhood to preschool, and the role of maternal depressive symptoms and parenting behavior as potential mediators. Participants included 115 mother-child dyads recruited from a hospital maternity ward. Maternal CM was measured at 3-months postpartum. At 18, 36, and 60 months, maternal depressive symptoms and child behavior were assessed via maternal report and parenting behavior was assessed through direct observation. Findings indicated that children of mothers exposed to CM demonstrated poorer trajectories of problem behavior across early childhood. Maternal depressive symptoms mediated the relation between CM and children's internalizing problems. Findings highlight the importance of screening for maternal depressive symptoms and early intervention for maternal and child mental health.

Depression Transmission From Parents to Their Adult Children in China: The Mediating Role of Family Violence

Depression can be transmitted from parents to children through the gene-environment interaction. Previous studies have focused on the short-term effects of parental depression on children and adolescents while neglecting the long-term effects. Furthermore, as a major indicator of stressful environment, the mediating role of different types of family violence has rarely been studied. The purpose of this study was to examine the long-term effects of parental depressive symptoms on those of adult children and to explore the potential mediating roles of different types of family violence (physical abuse, witnessing interparental violence, and sibling violence) in China. Data came from the 2014 and 2018 waves of the China Health and Retirement Longitudinal Study (CHARLS), which consisted of 10,973 participants aged 45 years and older. Logistic regression models were performed. The total effect was decomposed into direct and indirect effects by logistic regression based on the Karlson/Holm/Breen (KHB) method. The results indicated that parental depressive symptoms were related to adult children's depressive symptoms (odds ratio [OR], 1.20; 95% confidence interval [CI] [1.16-1.25]). The KHB method showed that this relationship was mediated by physical abuse (OR, 1.01; 95% CI [1.00-1.01]) and witnessing interparental violence (OR, 1.01; 95% CI [1.01-1.02]). In China, depression can be transmitted from parents to their adult children through family violence. The findings suggest that regular mental health screening across entire lifespan and family violence prevention programs targeting depressed parents may bring long-term benefit to adult children's mental health.

Maternal History of Childhood Adversities and Later Negative Parenting: A Systematic Review

Adverse childhood experiences negatively impact future violence, victimization, perpetration, health, and lifelong development. The aim of the present study was to systematically review the scientific evidence of empirical studies on the association between maternal childhood adversity in a familial context, including maltreatment, household challenges, and later maternal negative parenting. A search was performed in the PubMed, PsycINFO, Web of Science, SciELO, and LILACS databases, using the combination of the following keywords: (neglect OR abuse OR maltreatment OR harsh parenting OR punishment OR discipline OR negative parenting practices) AND (adverse childhood experiences OR early adversity OR cycle of violence OR cycle of maltreatment OR history of maltreatment) AND (mother OR maternal). The results of 29 studies showed predominantly significant direct associations between maternal childhood adversities and negative parenting with their children (83%). Parental stress was also significantly associated with a maternal history of childhood adversities. Focusing on the type of maltreatment practices, there were similar intergenerational transmission types: homotypic and heterotypic. Few studies have examined the protective factors that could buffer the negative impact of a maternal childhood history of adversities on later negative parenting.

Parents' history of childhood interpersonal trauma and postpartum depressive symptoms: The moderating role of mindfulness

Postpartum depression is the most commonly reported mental health issue among parents welcoming a new child, with long-term impacts on the well-being of their family. Survivors of childhood interpersonal trauma (CIT) appear to be more vulnerable with higher rates of postpartum depressive symptoms. Yet, studies are needed on protective mechanism that can buffer the link between CIT and postpartum depressive symptoms, to identify factors that can promote resilience in CIT survivors as they navigate this demanding period. Studies also need to include both parents to adopt a comprehensive dyadic perspective. This study examined the moderating role of mindfulness, a protective mechanism documented as key for both postpartum mental health and trauma processing, in the association between CIT and postpartum depressive symptoms in parental couples. A randomly selected sample of 843 couples who recently welcomed a new child completed self-reported measures of CIT, dispositional mindfulness and postpartum depression. Path analyses showed that more experience of CIT was associated with higher levels of postpartum depression, but this association was weaker in parents with higher dispositional mindfulness. Exploration of mindfulness facets yielded that higher disposition to act with awareness and observation acted as specific buffers, for fathers and mothers respectively. In addition, more CIT reported by one parent was linked with their partner's higher depressive symptoms. These findings shed light on the protective role of mindfulness during the postpartum period to protect against postpartum depression in parents who are CIT survivors and their partners.

Breaking the Cycle of Intergenerational Childhood Maltreatment: Effects on Offspring Mental Health

This study evaluated how continuities and discontinuities in the intergenerational transmission of maltreatment affect offspring psychopathology. Data from a multigenerational prospective, longitudinal study were used to compare the severity of offspring psychopathology in families with no history of maltreatment (controls) and those in which parents, offspring, or both experienced childhood maltreatment (cycle breakers, initiators, and maintainers, respectively). Participants included 454 parents (M_age = 47.1, SD_age = 3.4) and their 697 offspring (M_age = 22.3, SD_age = 6.3). Offspring of cycle breakers reported less psychopathology than offspring of cycle maintainers and did not report more psychopathology than offspring of controls. Offspring of cycle initiators and maintainers reported comparable levels of psychopathology. Results suggest that breaking the cycle of maltreatment buffers offspring from risk for psychopathology associated with parental maltreatment, with no enduring or additive effects of maltreatment across generations. Our findings highlight the need for maltreatment prevention programs and further research to identify conditions and characteristics that reduce the probability of intergenerational transmission.

Testing the Ecophenotype Model: Cortical Structure Alterations in Conduct Disorder With Versus Without Childhood Maltreatment

BACKGROUND

Childhood maltreatment is common in youths with conduct disorder (CD), and both CD and maltreatment have been linked to neuroanatomical alterations. Nonetheless, our understanding of the contribution of maltreatment to the neuroanatomical alterations observed in CD remains limited. We tested the applicability of the ecophenotype model to CD, which holds that maltreatment-related psychopathology is (neurobiologically) distinct from psychopathology without maltreatment.

METHODS

Surface-based morphometry was used to investigate cortical volume, thickness, surface area, and gyrification in a mixed-sex sample of participants with CD (n = 114) and healthy control subjects (HCs) (n = 146), ages 9 to 18 years. Using vertexwise general linear models adjusted for sex, age, total intracranial volume, and site, the control group was compared with the overall CD group and the CD subgroups with (n = 49) versus without (n = 65) maltreatment (assessed by the Children's Bad Experiences interview). These subgroups were also directly compared.

RESULTS

The overall CD group showed lower cortical thickness in the right inferior frontal gyrus. CD youths with a history of maltreatment showed more widespread structural alterations relative to HCs, comprising lower thickness, volume, and gyrification in inferior and middle frontal regions. Conversely, CD youths with no history of maltreatment only showed greater left superior temporal gyrus folding relative to HCs. When contrasting the CD subgroups, those with maltreatment displayed lower right superior temporal gyrus volume, right precentral gyrus surface area, and gyrification in frontal, temporal, and parietal regions.

CONCLUSIONS

Consistent with the ecophenotype model, findings indicated that CD youths with versus without maltreatment differ neurobiologically. This highlights the importance of considering maltreatment history in neuroimaging studies of CD and other disorders.

The Relationship Between a Lifetime History of Sexual Victimization and Perinatal Depression: A Systematic Review and Meta-Analysis

BACKGROUND

The association between a lifetime history of sexual victimization and the well-being of women during the perinatal period has received increasing attention. However, research investigating this relationship has yet to be systematically reviewed or quantitatively synthesized.

AIM

This systematic review and meta-analysis aims to calculate the pooled effect size estimate of the statistical association between a lifetime history of sexual victimization and perinatal depression (PND).

METHOD

Four bibliographic databases were systematically searched, and reference harvesting was conducted to identify peer-reviewed articles that empirically examined associations between a lifetime history of sexual victimization and PND. A random effects model was used to ascertain an overall pooled effect size estimate in the form of an odds ratio and corresponding 95% confidence intervals (CIs). Subgroup analyses were also conducted to assess whether particular study features and sample characteristic (e.g., race and ethnicity) influenced the magnitude of effect size estimates.

RESULTS

This review included 36 studies, with 45 effect size estimates available for meta-analysis. Women with a lifetime history of sexual victimization had 51% greater odds of experiencing PND relative to women with no history of sexual victimization (OR = 1.51, 95% CI [1.35, 1.67]). Effect size estimates varied considerably according to the PND instrument used in each study and the racial/ethnic composition of each sample.

CONCLUSION

Findings provide compelling evidence for an association between a lifetime history of sexual victimization and PND. Future research should focus on screening practices and interventions that identify and support survivors of sexual victimization perinatally.

The impact of maternal childhood maltreatment on child externalizing behaviour and the mediating factors underlying this association: a three-level meta-analysis and systematic review

Child maltreatment can negatively impact not only survivors but also survivors' children. However, research on the intergenerational effect of maternal childhood maltreatment on child externalizing behaviour has yielded contradictory results and has not yet been systematically synthesised. The current three-level meta-analysis and systematic review aimed to provide a quantitative estimate of the strength of the association between maternal childhood maltreatment and child externalizing behaviour and to summarise research on potential mediating factors of this association. PsycINFO, PubMed, and Embase were searched and 39 studies with 82 effects sizes were included in the meta-analysis. Results revealed a small significant association between maternal childhood maltreatment and child externalizing behaviour (r = 0.16; 95% CI 0.12-0.19; publication bias-adjusted effect size: r = 0.12, 95% CI 0.08-0.16). Maternal mental health, particularly depressive symptoms, maternal parenting and children's maltreatment exposure were the most frequently examined mediators of this association, with relatively robust mediating effects for children's maltreatment exposure and maternal depressive symptoms, but mixed evidence for the mediating role of maternal parenting. This meta-analysis provides evidence for a small but significant association between maternal childhood maltreatment and children's externalizing behaviour, emphasizing the need to develop effective preventive and intervention strategies to minimise the effects of childhood maltreatment on the next generation.

Stressful life events: Typology of aggression and mistreatment in male perpetrators of gender-based violence

The objective of this study was to analyze groups based on the stressful life events suffered and to know the relationship of these profiles with the type of abuse exercised against women in the couple. A sample of 118 heterosexual men who perpetrated gender-based violence was used, with a mean age of 40.46 years (SD = 11.14). The results show that those who suffered a greater number of adverse experiences abused their partners more frequently and with a more aggravated character. In addition, knowing typologies based on previous stressful life events could favor specific interventions in the elimination of the normalization of violence as a maladaptive relational strategy. It is necessary to continue investigating the characteristics of men who exercise gender-based violence, as well as to analyze previous exposure to violence in the family of origin due to the influence it exerts on subsequent abuse.

Tunisian maltreating mothers characteristics

Introduction

the aim of our cross-sectional study was to compare the sociodemographic and clinical characteristics, the social support, the personal history of abuse, and the parental bonding style of maltreating Tunisian mothers to those of nonmaltreating mothers.

Methods

this was a cross-sectional study carried out on the child psychiatry department of Mongi Slim Hospital in Tunisia. A data-collection sheet was designed to collect sociodemographic and clinical data about the child and the maltreatment (type, frequency, and duration), the mother of the child (sociodemographic and clinical data) and the family (socioeconomic situation and conjugal violence).

Results

the sample was composed of 167 mothers. Children were significantly more maltreated when their ages were between 6 and 12 years (p=0.004) and less maltreated when they had been born prematurely (p=0.007). Also, the higher the level of the mother´s education, the less the child was maltreated (p=0.007). In addition, maltreated mothers more frequently had a history of physical abuse, emotional abuse, or emotional neglect during their childhood (p values were respectively 0.002, 0.05, and 0.007). Thus, when mothers maltreated their children, a perception of optimal grandmother-mother parenting was significantly less frequent, and a perception of an affectionless-bonding grandmother-mother was significantly frequent (p = 0.019).

Conclusion

we conclude that it is important to consider individual, relational, communal, and social factors to elaborate efficient strategies for preventing children maltreatment.

Identifying Risk and Resilience Factors in the Intergenerational Cycle of Maltreatment: Results From the TRANS-GEN Study Investigating the Effects of Maternal Attachment and Social Support on Child Attachment and Cardiovascular Stress Physiology

Introduction

Childhood maltreatment (CM) is a developmental risk factor and can negatively influence later psychological functioning, health, and development in the next generation. A comprehensive understanding of the biopsychosocial underpinnings of CM transmission would allow to identify protective factors that could disrupt the intergenerational CM risk cycle. This study examined the consequences of maternal CM and the effects of psychosocial and biological resilience factors on child attachment and stress-regulatory development using a prospective trans-disciplinary approach.

Methods

Mother-child dyads (N = 158) participated shortly after parturition (t 0), after 3 months (t 1), and 12 months later (t 2). Mothers' CM experiences were assessed at t 0, attachment representation at t 1 and psychosocial risk and social support were assessed at t 1 and t 2. At t 2, dyads participated in the Strange Situation Procedure (SSP). Children's attachmen status were classified as organized vs. disorganized, including their level of disorganized behavior, and heart rate (HR) and respiratory sinus arrhythmia (RSA) were recorded as stress response measures of the autonomic nervous system. Maternal caregiving during SSP was assessed using the AMBIANCE scale. Child's single nucleotide polymorphisms rs2254298 within the oxytocin receptor (OXTR) and rs2740210 of the oxytocin gene (OXT) were genotyped using DNA isolated from cord blood.

Results

Maternal CM experiences (CM+) were significantly associated with an unresolved attachment status, higher perceived stress and more psychological symptoms. These negative effects of CM were attenuated by social support. As expected, maternal unresolved attachment and child disorganized attachment were significantly associated. Maternal caregiving did not mediate the relationship between maternal and child attachment but influenced children's HR and RSA response and disorganized behavior. Moreover, the rs2254298 genotype of the OXTR gene moderated the stress response of children from mothers with CM. Children carrying the rs2740210 risk allele of the OXT gene showed more disorganized behavior independent from maternal CM experiences.

Conclusion

We replicated and extended existing CM and attachment models by co-examining maternal attachment, social support, and child genetic susceptibility on child attachment and cardiovascular stress regulation. The findings contribute to an extended understanding of risk and resilience factors and enable professionals to target adequate services to parents and children at risk.

The intergenerational transmission of maternal adverse childhood experiences on offspring's psychiatric disorder and the mediating role of maternal depression: Results from a cross sectional study

Maternal adverse childhood experiences (ACEs) may negatively affect the mental health and development of their offspring. The purpose of this study was to investigate the association of maternal ACE and offspring's psychiatric disorder and the mediating effect of maternal depression. The subjects included 463 mothers (42.78 ± 5.68 years) and their offspring aged 6-18 years (13.26 ± 3.90 years). Mothers reported their ACE before age 18 and completed the Beck Depression Inventory-II and Diagnostic Predictive Scales (DPS), a screening tool for offspring's psychiatric disorder. 35.42% of subjects had at least one ACE, and 11.0% reported three or more ACEs. Higher maternal ACE scores were associated with a significantly higher prevalence of offspring's psychiatric disorders (p < 0.001). Household dysfunction of maternal ACE (OR = 2.263, p < 0.001) is significantly associated with offspring's psychiatric disorder. In the mediation model in which the household dysfunction affects the number of offspring's psychiatric disorders, the partial mediation model through maternal depression was significant. The mother's experience of household dysfunction before the age of 18 has a significant impact on her offspring's psychiatric disorder and supported significant mediation through maternal depression. Further research is needed to determine the mechanisms of intergenerational transmission of ACE and offspring's psychopathology.

Intergenerational transmission of maternal childhood adversity and depression on children's internalizing problems

OBJECTIVE

Childhood trauma exacts a lasting toll on one's own mental health and the health of one's offspring; however, limited research has examined the pathways through which this intergenerational transmission occurs. This study aimed to identify the transactions and mechanisms that link maternal early life trauma, maternal depressive symptoms, and children's internalizing symptoms.

METHOD

A pregnancy cohort of N = 1462 mothers (66% Black, 32% White, 2% Other race) reported their childhood trauma exposure and depressive symptoms during pregnancy. Maternal depressive and children's internalizing symptoms were measured repeatedly when offspring were 12, 24, 36, and 48-60 months of age. A path model tested the transactional associations between maternal and child symptomatology and mediation of maternal childhood trauma on offspring symptoms via maternal depressive symptoms.

RESULTS

Mothers' childhood trauma history was related to greater prenatal and postnatal (12 and 24 months) maternal depressive symptoms, which were prospectively associated with offspring internalizing problems at 36 and 48-60 months. Child-directed effects on maternal depressive symptoms were not observed. The association of maternal trauma on children's internalizing at 36 months was mediated by maternal depressive symptoms at 24 months.

LIMITATIONS

Assessments of the key study variables were provided by mothers. Childhood trauma was evaluated retrospectively.

CONCLUSION

Women's experiences of adversity in childhood have persistent and cumulative effects on their depression during the transition to parenthood, which is associated with risk for children's internalizing. Given the two-generation influence of maternal childhood trauma exposure, attending to its impact may protect both caregivers and their children.

Mediators and moderators in the relationship between maternal childhood adversity and children's emotional and behavioural development: a systematic review and meta-analysis

Maternal experiences of childhood adversity can increase the risk of emotional and behavioural problems in their children. This systematic review and meta-analysis provide the first narrative and quantitative synthesis of the mediators and moderators involved in the link between maternal childhood adversity and children's emotional and behavioural development. We searched EMBASE, PsycINFO, Medline, Cochrane Library, grey literature and reference lists. Studies published up to February 2021 were included if they explored mediators or moderators between maternal childhood adversity and their children's emotional and behavioural development. Data were synthesised narratively and quantitatively by meta-analytic approaches. The search yielded 781 articles, with 74 full-text articles reviewed, and 41 studies meeting inclusion criteria. Maternal mental health was a significant individual-level mediator, while child traumatic experiences and insecure maternal-child attachment were consistent family-level mediators. However, the evidence for community-level mediators was limited. A meta-analysis of nine single-mediating analyses from five studies indicated three mediating pathways: maternal depression, negative parenting practices and maternal insecure attachment, with pooled indirect standardised effects of 0.10 [95% CI (0.03-0.17)), 0.01 (95% CI (-0.02 to 0.04)] and 0.07 [95% CI (0.01-0.12)], respectively. Research studies on moderators were few and identified some individual-level factors, such as child sex (e.g. the mediating role of parenting practices being only significant in girls), biological factors (e.g. maternal cortisol level) and genetic factors (e.g. child's serotonin-transporter genotype). In conclusion, maternal depression and maternal insecure attachment are two established mediating pathways that can explain the link between maternal childhood adversity and their children's emotional and behavioural development and offer opportunities for intervention.

The Intergenerational Impact of Structural Racism and Cumulative Trauma on Depression

Depression among individuals who have been racially and ethnically minoritized in the United States can be vastly different from that of non-Hispanic White Americans. For example, African American adults who have depression rate their symptoms as more severe, have a longer course of illness, and experience more depression-associated disability. The purpose of this review was to conceptualize how structural racism and cumulative trauma can be fundamental drivers of the intergenerational transmission of depression. The authors propose that understanding risk factors for depression, particularly its intergenerational reach, requires accounting for structural racism. In light of the profoundly different experiences of African Americans who experience depression (i.e., a more persistent course of illness and greater disability), it is critical to examine whether an emerging explanation for some of these differences is the intergenerational transmission of this disorder due to structural racism.

Maternal childhood abuse and neglect predicts offspring development in early childhood: The roles of reflective functioning and child sex

BACKGROUND

Recent evidence suggests that offspring of mothers having been exposed to childhood abuse and neglect (CA&N) are at increased risk of developmental problems and that boys are more affected by maternal CA&N than girls. Since impairments in reflective functioning (RF) have been associated with maternal CA&N and offspring development, RF could represent a key mechanism in these intergenerational risk trajectories.

OBJECTIVE

This study evaluated mediating (RF) and moderating (child sex) mechanisms in the association between maternal CA&N and child development.

PARTICIPANTS AND SETTING

In a longitudinal setting, 111 mothers completed measures during pregnancy and between 11 and 36 months postpartum.

METHODS

CA&N and impairments in RF were assessed during pregnancy and offspring development was measured during the longitudinal follow-up using the Ages and Stages Questionnaires (ASQ-3). Child development was operationalized in two ways: using the global score at the ASQ-3 and using a dichotomous score of accumulation of delays across domains of development.

RESULTS

Structural equation modeling indicated that RF mediated the association between maternal CA&N and offspring development. Child sex moderated the association between CA&N and the clustering of developmental problems (Wald = 5.88, p = 0.02), with boys being particularly likely to accumulate developmental delays when their mother experienced CA&N (RR = 2.62). Accumulation of developmental problems was associated with impairments in maternal RF in girls and with maternal exposure to CA&N in boys.

CONCLUSIONS

Results provide novel insights on the role of mentalization and child sex in the association between maternal CA&N and child development.

Adverse Childhood Events and Substance Misuse in Men Who Perpetrated Intimate Partner Violence

Adverse childhood events related to violence suffered have developmental consequences such as the reproduction of such violence in intimate relationships and substance misuse in the later life trajectory. The objective of this study was to analyze the relationship between suffering adverse childhood events and excessive consumption of alcohol and drugs in 120 men, with a mean age of 40.51 years (SD = 11.06), who have abused women in a relationship. The results indicate that those who suffered abuse in childhood and other adverse childhood events in the family of origin consumed alcohol and drugs in excess. Furthermore, the regression models show that alcohol consumption is related to previous substance use by parents, while drug use is related to leaving home due to family conflicts. Also, the consumption of alcohol and other substances is likewise associated with consumption by parents and conflicts within the family. The size of the effect of the relationship increases when different forms of poly-victimization coexist. Conflict treatment is necessary in any setting, especially when it takes place in the family environment and at an early age, to avoid the transmission of maladaptive behaviors associated with substance misuse and violence.

It's not always binary: Connecting the continuum of caregiver depression with child adjustment in children who are high risk for maltreatment

BACKGROUND

Young children living with a depressed parent are at risk for developing social, behavioral, and emotional problems. The purpose of this study was to evaluate whether an increase in subclinical caregiver depression scores was associated with increases in internalizing and externalizing behavior in children who are at high risk for maltreatment.

METHODS

The 1019 U.S.-based dyads consisted of predominantly single (45.53%) and Black/African American (53.29%) caregivers and high-risk 4-year-olds from the LONGSCAN study. Multivariate regression analyzes were used to evaluate the relationship between caregiver Center for Epidemiological Studies-Depression (CES-D) scores, above and below the at-risk for depression CES-D score, and preschooler internalizing, externalizing, and total problem behaviors, measured with the Child Behavior Checklist (CBCL).

RESULTS

Caregiver CES-D score increases, above and below the at-risk for depression score, were significantly associated (p < 0.05) with increased child internalizing, externalizing, and total problem behaviors. After adjusting for covariates, among dyads whose caregivers had subclinical (CES-D < 16) scores, a one-unit score increase was significantly associated with a 0.43 increase (p = 0.00) in children's CBCL internalizing score.

LIMITATIONS

These findings are restricted to preschool children who are at risk for maltreatment, limiting generalizability.

CONCLUSIONS

Low and moderate levels of caregiver depressive symptomatology were associated with a negative influence on preschoolers' adjustment. Practitioners should consider that the link between caregiver depression and child wellbeing may lie on a continuum. With consideration of the full continuum of symptoms, early intervention and anticipatory guidance may decrease the impact of depression on the caregiver, child, and system.

Maternal childhood maltreatment and perinatal outcomes: A systematic review

BACKGROUND

Maternal childhood maltreatment (MCM) is linked to poor perinatal outcomes but the evidence base lacks cohesion. We explore the impact of MCM on four perinatal outcome domains: pregnancy and obstetric; maternal mental health; infant; and the quality of the care-giving environment. Mechanisms identified in the included studies are discussed in relation to the maternal programming hypothesis and directions for future research.

METHOD

We completed a comprehensive literature search of eight electronic databases. Independent quality assessments were conducted and PRISMA protocols applied to data extraction.

RESULTS

Inclusion criteria was met by N = 49 studies. MCM was consistently associated with difficulties in maternal and infant emotional regulation and with disturbances in the mother-infant relationship. Directly observed and maternal-reported difficulties in the mother-infant relationship were often mediated by mothers' current symptoms of psychopathology. Direct and mediated associations between MCM and adverse pregnancy and obstetric outcomes were suggested by a limited number of studies. Emotional and sexual abuse were the most consistent MCM subtype significantly associated with adverse perinatal outcomes.

LIMITATIONS

A meta-analysis was not possible due to inconsistent reporting and the generally small number of studies for most perinatal outcomes.

CONCLUSIONS

MCM is associated with adverse perinatal outcomes for mothers' and infants. Evidence suggests these associations are mediated by disruptions to maternal emotional functioning. Future research should explore biological and psychosocial mechanisms underpinning observed associations between specific subtypes of MCM and adverse perinatal outcomes. Services have a unique opportunity to screen for MCM and detect women and infants at risk of adverse outcomes during the perinatal period.

Preferences and Barriers to Counseling for and Treatment of Intimate Partner Violence, Depression, Anxiety, and Posttraumatic Stress Disorder Among Postpartum Women: Study Protocol of the Cross-Sectional Study INVITE

The cross-sectional study INVITE (INtimate partner VIolence care and Treatment prEferences in postpartum women) aims to examine treatment and counseling preferences and barriers in relation to the experience of intimate partner violence (IPV), depression and anxiety, and (childbirth-related) posttraumatic stress disorder (PTSD) among postpartum women in Dresden, Germany. Currently, the INVITE study consists of an interim sample of N = 1,787 participants with n = 891 completed interviews. Recruitment is ongoing, targeting a community sample of at least N = 4,000 women who complete various quantitative questionnaires via telephone interviews at 3-4 months postpartum. The differences in rates of IPV, postpartum depression and anxiety, and/or (childbirth-related) PTSD as well as treatment and counseling preferences and barriers between affected and non-affected women will be assessed. Further, predisposing variables, past and present stress exposure, enabling resources, as well as past and present health will be examined as predictors of service preferences and barriers. In this study protocol, the theoretical background, methods, as well as preliminary results regarding sociodemographic characteristics and birth-related factors of the interim sample are presented and discussed in terms of their socio-political relevance. Simultaneously assessing IPV, postpartum depression and anxiety, and (childbirth-related) PTSD will facilitate exploring comorbidities and concomitant special needs of affected women. Results of the INVITE study will therefore set the ground for well-aimed development and improvement of treatment and counseling services for the respective target groups by informing health care professionals and policy makers about specific preferences and barriers to treatment. This will yield the possibility to tailor services to the needs of postpartum women.

Intergenerational Effect of Maternal Childhood Maltreatment on Next Generation's Vulnerability to Psychopathology: A Systematic Review With Meta-Analysis

Many studies have identified the multiple negative consequences of childhood maltreatment on subsequent mental health. However, research on the intergenerational effect of maternal childhood maltreatment has not been systematically synthesized. This meta-analysis aimed to provide a quantitative estimate of the intergenerational effect of maternal childhood maltreatment on their offspring's psychopathology. Electronic databases and gray literature were searched for English-language prospective cohort studies. Two reviewers independently extracted data and assessed study quality with the Newcastle-Ottawa Scale. This review only included those studies with (1) maternal childhood maltreatment occurring prior to 18 years of age, (2) using a clear and reliable assessment for maltreatment exposure and offspring's mental health problems prior to age 18. Random-effect models were used to calculate the pooled effect size of maternal childhood maltreatment on offspring's psychopathology, and meta-regression was used to explore potential confounders. Twelve studies met eligibility criteria. Significant heterogeneity was found across selected studies. Maternal childhood maltreatment was found to have a small but significant effect on the offspring's depression and internalizing behaviors (r = .14, 95% confidence interval [.09, .19]). Two moderators were found, maternal depression and ethnicity. Maternal depression reduced the effect size of maternal maltreatment on offspring's depression and internalizing disorders. The offspring of non-Caucasian mothers who had a history of childhood maltreatment faced a higher risk of mental health problems. There was no evidence of publication bias. This review provides robust evidence to reinforce the need for policies to reduce its occurrence, as it can influence not just one but two or possibly more generations.

Intergenerational Continuity in Child Maltreatment: Explicating Underlying Mechanisms

The current study examined direct and indirect effects of a mother's history of childhood physical and sexual abuse on her child's officially reported victimization. This prospective, longitudinal study followed a community-based sample of 499 mothers and their children. Mothers (35% White/non-Latina, 34% Black/non-Latina, 23% Latina, and 7% other) were recruited and interviewed during pregnancy, and child protective services records were reviewed for the presence of the participants' target child between birth and age 3.5. Whereas both types of maternal maltreatment history doubled the child's risk of child protective services investigation, mothers' sexual abuse history conferred significantly greater risk. Pathways to child victimization varied by type of maternal maltreatment history. Mothers who had been physically abused later demonstrated interpersonal aggressive response biases, which mediated the path to child victimization. In contrast, the association between maternal history of sexual abuse and child victimization was mediated by mothers' substance use problems. Study implications center on targeting child maltreatment prevention efforts according to the mother's history and current problems.

The Impact of Maternal Adverse Childhood Experiences on Offspring's Internalizing and Externalizing Problems

OBJECTIVE

Adverse childhood experiences (ACEs) are associated with negative physical and mental health outcomes across the lifespan, but research on intergenerational transmission of maternal ACEs and its impact on the offspring's mental health problems are limited. The study examines the effects of maternal ACEs on the risk of internalizing or externalizing problems among offspring.

METHODS

There were 450 mother-child dyads. Mothers completed the Adverse Childhood Experiences Questionnaire. The child outcomes included internalizing and externalizing problems assessed by the Korean Child Behavior Checklist (K-CBCL) and Korean Youth Self-Report (K-YSR), depression assessed by the Center for Epidemiological Studies Depression Scale for Children (CES-DC) and anxiety assessed by the Screen for Child Anxiety Related Emotional Disorders (SCARED).

RESULTS

36.1% of mothers experienced at least one ACE, and 11.1% experienced three or more ACEs. Cumulative maternal ACEs were associated with internalizing problems, externalizing problems, depression and anxiety in the offspring. Household dysfunction from maternal ACEs was significantly associated with delinquent behavior, anxiety/depression, and somatic complaints in the offspring.

CONCLUSION

The findings support the hypothesis that maternal ACEs are related to mental health problems in the offspring. Further research is needed to determine the factors mediating intergenerational transmission as well as intervention strategies to prevent ACEs and mental health problems in the offspring.

Intergenerational Cycles of Maltreatment: A Scoping Review of Psychosocial Risk and Protective Factors

Child maltreatment tends to show intergenerational continuity. However, a significant proportion of maltreated parents break these cycles. Since several studies have investigated risk and protective factors associated with the intergenerational continuity of child maltreatment over the past decades, and no systematic review of the literature is available, this scoping review aimed to summarize studies documenting associated psychosocial risk and protective factors. A secondary objective was to document the prevalence of this phenomenon. A search in six major databases (PsycINFO, Scopus, Medline, Social Work Abstracts, ProQuest Dissertations/Theses, and Web of Science) was conducted. Studies involving human participants, presenting original findings, written in French or English, and of any type of design were included. There was no limit regarding the date of publication, except for theses/dissertations (5 years). A final sample of 51 papers was retained, 33 providing data on risk and protective factors and 18 providing only prevalence data. Results indicate that parents' individual characteristics (e.g., mental health, age), childhood adversity (e.g., multiple forms of adversity), relational (e.g., couples' adjustment, attachment, social support), and contextual factors (e.g., disadvantage, community violence) are relevant to the intergenerational continuity of child maltreatment. Prevalence rates of continuity ranged from 7% to 88%. Major limitations of reviewed studies are discussed. Continued efforts to uncover the mechanisms associated with the intergenerational continuity of child maltreatment using strong methodological designs are necessary. Knowledge in this area could lead to the development of effective prevention strategies (e.g., mental health services for parents, family/dyadic interventions) to break harmful intergenerational cycles of violence.

Trends of Perinatal Stress, Anxiety, and Depression and Their Prediction on Postpartum Depression

Perinatal stress, anxiety, and depression impacts not only women but also their child(ren). The purpose of this longitudinal study is to explore trends of stress, anxiety, and depressive symptoms from pregnancy to postpartum and understand predictions of stress and anxiety on postpartum depression. One-hundred-fifty-six women at 23-28 weeks gestation (T1), 147 at 32-36 weeks gestation (T2), 129 at over 36 weeks gestation (T3), and 83 at postpartum (T4) completed study surveys. The Perceived Stress Scale, Center for Epidemiologic Studies Depression scale, and State-Trait Anxiety Inventory were used to measure stress, depressive symptoms, and anxiety. Descriptive statistics, Pearson and Spearman's correlation, and Generalized Estimating Equation were applied to analyze the data. Results showed that levels of anxiety and depressive symptoms increased from 24 weeks gestation to postpartum, whereas stress levels decreased during pregnancy but increased in postpartum. Over half of women experienced anxiety symptoms, especially during late pregnancy and postpartum. Stress, anxiety, and depressive symptoms were inter-correlated. Notably, women at late pregnancy and postpartum were prone to stress, anxiety, and depression. Prenatal anxiety could predict postpartum depressive symptoms. Active assessment and management of stress, anxiety, and depression is needed and should begin from early pregnancy and continue until postpartum.

Associations between childhood maltreatment and DNA methylation of the oxytocin receptor gene in immune cells of mother-newborn dyads

The neuropeptide oxytocin (OXT) and its receptor (OXTR) modulate interpersonal relationships, particularly mother-child interactions. DNA methylation (DNAm) changes of the OXTR gene were observed in individuals who experienced Childhood Maltreatment (CM). A modulatory role of single nucleotide polymorphisms (SNP) within OXTR in association with CM on the regulation of OXTR was also postulated. Whether these CM-induced epigenetic alterations are biologically inherited by the offspring remains unknown. We thus investigated possible intergenerational effects of maternal CM exposure on DNAm and OXTR gene expression, additionally accounting for the possible influence of three SNP: rs53576 and rs2254298 (OXTR gene), and rs2740210 (OXT gene). We used the Childhood Trauma Questionnaire to classify mothers into individuals with (CM+) or without CM (CM-). Maternal peripheral immune cells were isolated from venous blood (N = 117) and fetal immune cells from the umbilical cord (N = 113) after parturition. DNA methylation was assessed using MassARRAY. Taqman assays were performed for genotyping and gene expression analyses. Among mothers, CM was not associated with OXTR mean methylation or gene expression. However, four CpG sites showed different methylation levels in CM- compared to CM+. In mothers, the OXTR rs53576 and OXT rs2740210 allelic variations interacted with CM load on the OXTR mean methylation. Maternal and newborns' mean methylation of OXTR were positively associated within CM- dyads, but not in CM+ dyads. We show gene×environment interactions on the epigenetic regulation of the oxytocinergic signaling and show the intergenerational comparability of the OXTR DNAm might be altered in infants of CM+ mothers.

Psychometric properties of psychosocial dimensions associated with postpartum depression

AIM

The aim of the study was psychometric properties of a questionnaire for assessing psychosocial dimensions associated with postpartum depression (PAPP).

METHODS

Initial form of the questionnaire for assessing PAPP was developed based on the results of a qualitative study. Principal component analysis was used to determine the construct validity, as well as Cronbach's alpha and intraclass correlation coefficient to determine the reliability of the questionnaire. Construct validity, predictability of the questionnaire, and confirmatory factor analysis were evaluated in a longitudinal study on 303 pregnant women in the third trimester of pregnancy. Also, using Edinburgh postnatal depression scale, the level of depression was evaluated 6 weeks after childbirth.

RESULTS

Exploratory factor analysis led to a 47-item questionnaire with five dimensions and confirmed that five factors determined 42.31% variance. Cronbach's alpha was 0.851 for the total score of questionnaire and for the factors, ranged from 0.84 to 0.92. ICC of total was 0.92 (95% confidence interval (CI): 0.69-0.93). Analyzing the confirmatory factor analysis showed that the 47 items questionnaire had a good construct validity (CMIN/DF = 2.01, p = 0.122). The level of the PAPP in women suffered from postpartum depression was higher than women without postpartum depression (odds ratio = 1.01, 95% CI: 1.01-1.02, p = 0.001). A cut-off score of 42 provided the best sensitivity (0.75) and specificity (0.50) for PAPP.

CONCLUSION

The psychometric properties of the PAPP showed an appropriate validity and reliability, and it may applicable to predict of at risk pregnant women for postpartum depression who seeking antenatal care services.

Parental Depression and Contextual Selection: The Case of School Choice

Parental depression constricts children's development, but the mechanisms implicated-beyond daily parenting tactics-remain unknown. Today, parents must evaluate and select environmental contexts for child-rearing within increasingly complex residential and educational markets. Depression may hamper parents' abilities to navigate this terrain, constraining information collection and impairing child-oriented decision-making. In turn, depressed parents' children may lack access to developmentally enriching neighborhood, school, and child care settings. K-12 school sorting offers a strategic case to assess these expectations, given proliferating nontraditional options and school quality data. Analyses using the Los Angeles Family and Neighborhood Survey (N = 2,754) linked to administrative data suggest that depressed parents' children attend magnet, charter, or private schools at lower rates than similarly situated children of nondepressed parents; depression-based disparities appear largest among Latino and Black families. The study motivates future research examining whether the depression-contextual selection link mediates intergenerational processes and exacerbates segregation.

The impact of childhood trauma on psychological interventions for depression during pregnancy and postpartum: a systematic review

Women who have experienced childhood trauma (CT) are at increased risk for depression during pregnancy and postpartum, pregnancy complications, and adverse child outcomes. There are effective psychotherapeutic interventions to treat depression during pregnancy and postpartum, yet there is a paucity of literature on the impact of CT on treatment outcomes. This review aims to determine whether and how maternal CT history affects the outcomes of psychological interventions for depression during pregnancy and postpartum. PubMed, PsycINFO, and Cochrane Library searches were conducted to identify papers on psychological interventions designed to treat depression during pregnancy and postpartum in women with CT. Seven manuscripts, describing six studies, met the inclusion criteria (N = 1234). Three studies utilized core principles of interpersonal psychotherapy (IPT). Two studies investigated interventions based on cognitive behavioral therapy (CBT). One study was based on a psychoeducation component. Results suggest that IPT-based interventions are beneficial for women with CT. The evidence regarding CBT-based interventions is less conclusive. This review is written in light of the paucity of research addressing the question systematically. The Childhood Trauma Questionnaire (CTQ) was the main measure used to assess CT. Trauma related to accidents, illness, and political violence was not included. The results are only applicable to interventions based on either IPT or CBT and cannot be generalized to other forms of psychotherapy. Psychotherapeutic interventions are beneficial for depressed women with history of CT during pregnancy and postpartum; however, further systematic research is needed.

Polygenic risk for autism, attention-deficit hyperactivity disorder, schizophrenia, major depressive disorder, and neuroticism is associated with the experience of childhood abuse

People who experience childhood abuse are at increased risk of mental illness. Twin studies suggest that inherited genetic risk for mental illness may account for some of these associations. Yet, the hypothesis that individuals who have experienced childhood abuse may carry genetic loading for mental illness has never been tested with genetic data. Using polygenic risk scores for six psychiatric disorders-attention-deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), bipolar disorder (BPD), major depressive disorder (MDD), neuroticism, and schizophrenia-we tested whether genetic risk for mental illness was associated with increased risk of experiencing three types of childhood abuse: physical/emotional abuse, physical assault, and sexual abuse, in a cohort of white non-Hispanic women (n = 11,315). ADHD and MDD genetic risk scores were associated with a higher risk of experiencing each type of childhood abuse, while neuroticism, schizophrenia, BPD, and ASD genetic scores were associated with a higher risk of experiencing physical/emotional abuse and physical assault, but not sexual abuse. Sensitivity analyses examining potential bias from the differential recall of childhood trauma, parental socioeconomic status, and population stratification were consistent with the main findings. A one-standard-deviation increase in genetic risk for mental illness was associated with a modestly elevated risk of experiencing childhood abuse (OR range: 1.05-1.19). Therefore, inherited genetic risk may partly account for the association of childhood abuse with mental illness. In addition, future treatments for mental illness will benefit from taking into consideration the co-occurrence of childhood trauma and genetic loading.

Housing insecurity and adolescent well-being: Relationships with child welfare and criminal justice involvement

BACKGROUND

Housing insecurity is endemic among low-income, marginalized families throughout the United States. Unstably housed families face increased likelihood of coming into contact with various social systems that upend family routines and norms, but the roles of these contacts in linking housing insecurity with long-term adolescent outcomes are unknown.

OBJECTIVE

The present study tested whether family contacts with the criminal justice and child welfare systems mediated links between housing insecurity and adverse adolescent outcomes.

PARTICIPANTS AND SETTING

Data came from at-risk families with children born 1998-2000 in 20 large American cities followed over 15 years (N = 2,892).

METHODS

Structural equation modeling estimated a measurement model using confirmatory factor analysis and a structural model testing direct and indirect pathways from housing insecurity to adolescent depression and delinquency via contact with the criminal justice and child welfare systems.

RESULTS

Housing insecurity was associated with increased contact with both the criminal justice and child welfare systems. Housing insecurity at age 5 was directly associated with adolescent depression at age 15 (β = 0.09, p < 0.05) and indirectly associated with adolescent delinquency via mothers' criminal justice (β = 0.04, p < 0.05) and child welfare (β = 0.07, p < 0.05) contacts.

CONCLUSIONS

Families with high needs may face stigma or seek assistance that increases surveillance of families and thus likelihood for sanctioning by the criminal justice and child welfare systems. Providers and systems working with low-income, insecurely housed families must consider stigma faced by clients to avoid further marginalizing underserved populations.

Intimate partner violence against women and child maltreatment in a Brazilian birth cohort study: co-occurrence and shared risk factors

BACKGROUND

Intimate partner violence (IPV) against women and child maltreatment (CM) are major public health problems and human rights issues and may have shared causes. However, their overlap is understudied. We investigated the prevalence of IPV and CM, their co-occurrence in households and possible shared risk factors, in the general population of a Brazilian urban setting.

METHODS

Prospective population-based birth cohort, including over 3500 mother-child dyads with maternal reports on both IPV and CM when children were 4 years old. Eleven neighbourhood, family and parental risk factors were measured between birth and age 4 years. Bivariate and multivariate Poisson regression models with robust variance were used to test which potential risk factors were associated with IPV, CM and their co-occurrence.

RESULTS

The prevalence of any IPV and CM were 22.8% and 10.9%, respectively; the co-occurrence of both types of violence was 5%. Multivariate analyses showed that the overlap of IPV and CM was strongly associated with neighbourhood violence, absence of the child's biological father, paternal antisocial behaviour in general and a mother-partner relationship characterised by high levels of criticism, maternal depression and younger maternal age. A concentration of many risk factors among 10% of the population was associated with a sixfold increase in risk for overlapping IPV and CM compared with households with no risk factors.

CONCLUSION

IPV and CM share important risk factors in the family and neighbourhood environments and are particularly common in households with multiple social disadvantages and family difficulties. Integrated preventive interventions are needed.

Child maltreatment: An intergenerational cascades model of risk processes potentiating child psychopathology

BACKGROUND

Child maltreatment poses substantial risk for compromised mental health in children. Further, child abuse and neglect are potentiated within a cascade of intergenerational and current familial risk processes that require clarification to inform understanding of adverse outcomes and direct prevention and intervention efforts.

OBJECTIVE

Using a multi-informant design, the current study applied an intergenerational cascades approach to examine the interconnected pathways among several familial risk factors associated with child maltreatment and its consequences.

PARTICIPANTS

Participants were 378 children (aged 10-12) and their mothers from economically disadvantaged, ethnically diverse backgrounds. The sample included maltreated children recruited via CPS records and demographically comparable non-maltreated children.

METHODS

Structural equation modeling (SEM) was conducted to test sequential mediation pathways examining the independent and cascading effects of maternal history of childhood maltreatment, maternal adolescent childbearing, current maternal depression, and the child's lifetime history of maltreatment on the child's internalizing and externalizing symptoms.

RESULTS

Multigenerational developmental cascades were identified. Maternal history of maltreatment predicted chronic maltreatment for offspring, which in turn predicted greater internalizing (β = .167, p = .03) and externalizing symptoms (β = .236, p = .005) in late childhood. Similarly, children born to mothers who began childbearing in adolescence were more likely to experience chronic maltreatment during childhood and develop subsequent symptoms. Effects were found over and above a parallel cascade from maternal maltreatment to offspring psychopathology via a maternal depression pathway.

CONCLUSION

Findings reveal targets to prevent or ameliorate progressions of intergenerational risk pathways.

What Research Questions Should the Next Generation of Birth Cohort Studies Address? An International Delphi Study of Experts

OBJECTIVE

Birth cohort studies (BCS) have generated a wealth of invaluable basic scientific and policy-relevant information on a wide range of issues in child health and development. This study sought to explore what research questions are currently a priority for the next generation of BCS using a 3-round Delphi survey of interdisciplinary experts.

METHODS

Twenty-four (Round I, N = 17; Round II, N = 21; Round III, N = 18) experts across a wide range of fields (eg, psychology, public health, and maternal/child health) agreed to participate. In Round I, the expert panel was invited to freely respond to the question, "what are the key scientific questions future birth cohort studies should address?" Content analysis of answers was used to identify 47 questions for rating on perceived importance by the panel in Round II and consensus-achieving questions were identified. Questions that did not reach consensus in Round II were posed again for expert re-rating in Round III.

RESULTS

Twenty six of 47 questions reached consensus in Round II, with an additional 6 reaching consensus in Round III. Consensus-achieving questions rated highly on importance spanned a number of topics, including environmental effects on child development, intergenerational transmission of disadvantage, and designing BCS to inform intervention strategies.

CONCLUSION

Investigating the effects of family/environmental factors and social disadvantage on a child's development should be prioritized in designing future BCS. The panel also recommended that future BCS are designed to inform intervention strategies.
