Impact of maternal childhood trauma on child behavioral problems: The role of child frontal alpha asymmetry

A biomarker of brain arousal mediates the intergenerational link between maternal and child post-traumatic stress disorder

This study examined whether there is a biological basis in the child's resting brain activity for the intergenerational link between maternal interpersonal violence-related posttraumatic stress disorder (IPV-PTSD) and child subclinical symptoms. We used high-density EEG recordings to investigate the resting brain activity in a sample of 57 children, 34 from mothers with IPV-PTSD, and 23 from mothers without PTSD. These children were part of a prospective, longitudinal study focusing on the offspring of mothers with and without IPV-PTSD, reporting how the severity of a mother's IPV-PTSD can impact her child's emotional regulation and risk for developing mental illness. However, we had not yet looked into potential EEG biomarkers during resting state that might mediate and/or moderate effects of maternal IPV-PTSD severity on child mental health, and in particular the risk for PTSD. The alpha band spectral power as well as the aperiodic exponent of the power spectrum (PLE; power-law exponent) were examined as mediators of maternal IPV-PTSD and child PTSD. While there was no difference in alpha spectral power between the two groups, PLE was significantly reduced in children of mothers with IPV-PTSD compared to control children, indicating cortical hyper-arousal. Interestingly, child PLE was negatively correlated with the severity of maternal IPV-PTSD, suggesting an intergenerational interaction. This interpretation was reinforced by a negative correlation between child PLE and child PTSD symptoms. Finally, causal analyses using structural equation modelling indicated that child PLE mediated the relationship between maternal PTSD severity and child PTSD. Our observations suggest that maternal IPV-PTSD has an intergenerational impact on the child neurobehavioral development through a correlated abnormal marker of brain arousal (i.e. child PLE). These findings are potentially relevant to psychotherapy research and to the development of more effective psycho-neurobehavioral therapies (i.e. neurofeedback) among affected individuals.

Improving posttraumatic stress disorder assessment in young children: comparing measures and identifying clinically-relevant symptoms in children ages six and under

Young children exposed to trauma are vulnerable to developing posttraumatic stress disorder (PTSD). Although experts agree on the importance of tailoring PTSD assessments to be developmentally-appropriate for young children, there is little research on which assessment methods best identify clinically significant symptomatology in this difficult-to-assess population. Two competing models for assessing PTSD have been proposed by the DSM-5 and ICD-11. This study compared a DSM-5 measure to an ICD-11 measure in young children (ages 1-6) exposed to a natural disaster. The measures identified similar rates of PTSD in children; however, diagnostic agreement between the measures was low (31-36%). Both PTSD measures were associated with actual and perceived life threat, functional impairment, and comorbid psychopathology. PTSD symptom and cluster endorsement rates were also binned by age and compared to functional impairment to identify commonly-reported and highly impairing symptoms in trauma-exposed young children, as potential candidates for inclusion in future revisions of diagnostic criteria. Across age ranges, increased clinginess post-trauma was the most commonly reported symptom and was associated with functional impairment. Arousal symptoms (startle, hypervigilance) and Re-experiencing symptoms (nightmares) also emerged as relevant for young children. Findings may contribute to efforts to improve assessment for PTSD in young children.

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.

Parental Preconception Adversity and Offspring Mental Health in African Americans and Native Americans in the United States: A Systematic Review

This systematic review examines the impact of parental preconception adversity on offspring mental health among African Americans (AAs) and Native Americans (NAs), two populations that have experienced historical trauma and currently experience ethnic/racial mental health disparities in the United States. PsycINFO, PubMed, CINAHL, Scopus, and Web of Science were searched for studies that included at least two generations of AAs or NAs from the same family, measured parental preconception adversity and their offspring's mental health, and examined the association between these variables. Over 3,200 articles were screened, and 18 articles representing 13 unique studies were included in this review. Among the studies with samples that included AAs (n = 12, 92%), 10 (83%) reported a significant association between parental preconception adversity and adverse offspring mental health. The only study with a sample of NAs (n = 1, 8%) also reported a significant association between these variables. Although the literature suggests that parental preconception adversity is associated with offspring mental health among AAs and NAs, it must be interpreted in the context of the small number of studies on this topic and the less-than-ideal samples utilized-just one study included a sample of NAs and several studies (n = 6, 46%) used multi-ethnic/racial samples without testing for ethnic/racial disparities in their results. A more rigorous body of literature on this topic is needed as it may help explain an important factor underlying ethnic/racial mental health disparities, with important implications for interventions and policy.

Fetal Sex as Moderating Factor for the Relationship Between Maternal Childhood Trauma and Salivary Kynurenic Acid and Tryptophan in Pregnancy: A Pilot Study

Traumatic experiences and fetal development influence tryptophan (TRP) and its neuroactive byproduct, kynurenic acid (KYNA). Maternal TRP metabolite levels during pregnancy vary by fetal sex, with higher concentrations in mothers carrying male fetuses. This pilot study aimed to explore the relationship between offspring sex, maternal childhood trauma, and maternal salivary KYNA and TRP levels during pregnancy. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to determine KYNA and TRP levels in maternal saliva samples collected from 35 late-pregnancy participants. Maternal childhood trauma was assessed using the Childhood Trauma Questionnaire, including subscales for emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect. Among mothers pregnant with boys, salivary KYNA significantly correlated with physical and emotional neglect, and salivary TRP with emotional neglect. No significant correlations were found in mothers who delivered female offspring. Significant associations of childhood trauma and offspring sex were found for salivary KYNA but not TRP concentrations. Mothers with higher trauma levels who delivered boys exhibited higher levels of salivary KYNA compared to those with lower trauma levels. Moreover, mothers with higher trauma levels who delivered boys had higher salivary KYNA levels than those with higher trauma levels who delivered girls. This pilot study provides evidence of an association between maternal childhood trauma and TRP metabolism, measured in saliva, especially in mothers pregnant with boys. However, longitudinal studies with larger sample sizes are required to confirm these results.

The Impact of Maternal Interpersonal Violent Trauma and Related Psychopathology on Child Outcomes and Intergenerational Transmission

PURPOSE OF REVIEW

This review aims to outline some consequences that maternal history of trauma with and without related psychopathology, such as posttraumatic stress symptoms (PTSS), can have on their children's development and functioning. It then addresses mechanisms through which intergenerational transmission of interpersonal violence (IPV) and related psychopathology may occur.

RECENT FINDINGS

Findings include the effects of maternal IPV experience and related psychopathology on child social-emotional and biologically-based outcomes. This includes increased developmental disturbances and child psychopathology, as well as physiological factors. Secondly, the review focuses on psychobiological mechanisms by which maternal experience of IPV and related psychopathology likely trigger intergenerational effects. Maternal IPV and related psychopathology can have a negative impact on several areas of their child's life including development, interactive behavior, psychopathology, and physiology. This transmission may partially be due to fetal and perinatal processes, genetic and epigenetic effects, and interactions with their parents.

Examining the impact of prenatal maternal internalizing symptoms and socioeconomic status on children's frontal alpha asymmetry and psychopathology

Prenatal maternal internalizing psychopathology (depression and anxiety) and socioeconomic status (SES) have been independently associated with higher risk for internalizing and externalizing problems in children. However, the pathways behind these associations are not well understood. Numerous studies have linked greater right frontal alpha asymmetry to internalizing problems; however, findings have been mixed. Several studies have also linked maternal internalizing psychopathology to children's frontal alpha asymmetry. Additionally, emerging studies have linked SES to children's frontal alpha asymmetry. To date, only a limited number of studies have examined these associations within a longitudinal design, and the majority have utilized relatively small samples. The current preregistered study utilizes data from a large prospective study of young children (N = 415; Meanage  = 7.27 years; Rangeage  = 5-11 years) to examine the association between prenatal maternal internalizing symptoms, children's frontal alpha asymmetry, and behavior problems. Prenatal maternal internalizing symptoms did not predict children's frontal alpha asymmetry, and there was no association between frontal alpha asymmetry and behavior problems. However, mothers' internalizing symptoms during pregnancy predicted children's internalizing and externalizing outcomes. Non-preregistered analyses showed that lower prenatal maternal SES predicted greater child right frontal alpha asymmetry and internalizing problems. Additional non-preregistered analyses did not find evidence for frontal alpha asymmetry as a moderator of the relation between prenatal maternal internalizing psychopathology and SES to children's behavior problems. Future research should examine the impact of SES on children's frontal alpha asymmetry in high-risk samples.

The Role of Social Support in Perinatal Mental Health and Psychosocial Stimulation

Social support refers to the help someone receives emotionally or instrumentally from their social network. Poor social support in the perinatal period has been associated with increased risk for symptoms of common mental disorders, including depression and posttraumatic stress symptoms (PTS), which may impact parenting behavior. Whether social support impacts parenting behaviors, independent of mental health symptomatology, remains unclear. Among N=309 participants of the Scaling Up Maternal Mental healthcare by Increasing access to Treatment (SUMMIT Trial), a large perinatal depression and anxiety treatment trial, we explored the relations between perceived social support, perinatal depressive and PTS symptoms, and psychosocial stimulation provided by the parent in their home environment. Social support was measured at baseline using the Multidimensional Scale of Perceived Social Support (MSPSS). Perinatal depressive symptoms were measured by the Edinburgh Postnatal Depression Scale (EPDS) and PTS symptoms were measured by the Abbreviated PTSD Checklist (PCL-6) at baseline, 3-, and 6-months post-randomization. Psychosocial stimulation was assessed by the Home Observation Measurement of the Environment (HOME) when the infant was between 6 to 24 months. Using stepwise hierarchical regressions, we found: (1) perceived social support at baseline significantly predicted both depressive and PTS symptoms at 3-months post-randomization, even when controlling for baseline depressive and PTS symptoms; and (2) while neither depressive nor PTS symptoms were significantly associated with psychosocial stimulation, perceived social support at baseline was a significant predictor. Clinical implications regarding treatment of perinatal patients are discussed.

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

Adverse childhood experiences (ACEs) are among the leading environmental causes of morbidity and mortality. Extending research on within-generation effects, more recent scholarship has explored between-generation consequences of ACEs. Despite growing interest in the intergenerational effects of parents' ACEs on children's outcomes, this line of scholarship has yet to be coalesced into a comprehensive review. The current study is a scoping review on the intergenerational transmission of parental ACEs and children's outcomes. Ten databases such as PubMed, APA PsycArticles, and Social Work Abstracts were searched. To be included, empirical studies must have been published in English and analyzed associations between a cumulative measure of at least four parental ACEs and children's outcomes. Sixty-eight studies qualified for the review and, among these, 60 were published in the most recent 5 years (2018-2022). Fifty-one studies had sample sizes smaller than 500, and 55 focused on the effect of maternal ACEs. Nearly all studies demonstrated that parental ACEs could affect children's outcomes directly or indirectly via mechanisms like maternal mental health problems or parenting-related factors. By scoping the extant literature, this review advances the knowledge base regarding the intergenerational impacts of parental childhood trauma and children's outcomes. It also reveals methodological limitations that should be addressed in future research to strengthen causal inferences along with practical implications for interventions that aim to interrupt the intergenerational transmission of trauma.

Providing patient-centred care as Medical Radiation Practitioners to children and young persons in out of home care

Modern healthcare focuses on patient-centred care where patients' needs, beliefs, choices and preferences are valued and lead to better health outcomes. Children and young persons in out of home care (OOHC) require more health care services compared with children from similar social and economic backgrounds. Each state and territory government are responsible for statutory child protection in Australia. If a child is unsafe in their current environment, they may be removed and placed into OOHC where they have ongoing case management with either a government or non-government agency. Complex trauma is the prolonged and uncontrolled exposure to traumatic events, like those experienced by maltreated children. Complex trauma can create a toxic stress response that produces biological alteration to the developing brain and affects the lives of the child, other family members and their descendants. Children with complex trauma often do not have the ability to regulate their responses to stimuli, reacting to minor triggers with disproportionate reactions. Many of these children will present with challenging behaviours. Trauma-informed care is a method of service delivery that seeks to actively minimise re-traumatisation. Creating a safe space is an essential element of trauma-informed care. Children with a history of complex trauma have life experiences that may be re-lived in a healthcare setting. There are ethical and legal considerations like privacy, consent and mandatory reporting when dealing with children in OOHC. By practising trauma-informed care Medical Radiation Practitioners can minimise further trauma to one of the most vulnerable population groups in Australia.

Intergenerational effects of childhood maltreatment: The relationships among parental childhood emotional neglect, emotional expressiveness and children's problem behaviors

BACKGROUND

Childhood maltreatment has a severe impact on both the health and parenting styles of abused individuals in adulthood, and it even has a negative impact on the offspring of abused individuals. Although studies have confirmed the intergenerational effects of childhood maltreatment, relatively few have emphasized emotional neglect and its mechanism of intergenerational effects. Additionally, few studies have examined the unique role of fathers and how mothers and fathers interact with one another.

OBJECTIVE

The current study aimed to employ the actor-partner interdependence mediation model to investigate the relationship between parental childhood emotional neglect and children's problem behaviors, as well as whether parents' positive and negative emotional expressiveness plays a mediating role.

METHODS, PARTICIPANTS, AND SETTING

In total, 397 dyads of mothers and fathers of children aged 6-9 were recruited and reported their childhood emotional neglect experience and emotional expressiveness, and mothers also rated their children's problem behaviors.

RESULTS

The findings revealed that (a) maternal childhood emotional neglect was associated solely with mothers' own negative emotional expressiveness, followed by their children's problem behavior and (b) paternal childhood emotional neglect showed no effect on children's problem behavior through fathers' own or their spouses' positive and negative emotional expressiveness.

CONCLUSIONS

The findings of this study suggest that childhood emotional neglect has intergenerational effects and that mothers' parenting behaviors are relatively important in preventing adverse effects on their children.

Prefrontal activation in preschool children is associated with maternal adversity and child temperament: A preliminary fNIRS study of inhibitory control

Exposure to adversity is a well-documented risk factor for cognitive, behavioral, and mental health problems. In fact, the consequences of adversity may be intergenerational. A growing body of research suggests that maternal exposures to adversity, including those prior to childbirth, are associated with offspring biobehavioral development. In a sample of 36 mothers and their preschool-age children (mean child age = 4.21 ± 0.92 years), we used functional near-infrared spectroscopy to replicate and extend this work to include brain activation during inhibitory control in young children. We found that measures of maternal exposure to adversity, including cumulative, childhood, and preconception exposures, were significantly and positively associated with activation in the right frontopolar prefrontal cortex (PFC) and in the left temporal and parietal clusters during inhibitory control. In addition, and consistent with previous findings, children's increased negative affect and decreased effortful control were associated with increased right PFC activation during inhibitory control. These findings provide preliminary evidence that maternal and dispositional risk factors are linked to alterations in PFC functioning during the preschool years. Children of mothers with a history of exposure to adversity, as well as children who are less temperamentally regulated, may require increased neural resources to meet the cognitive demands of inhibitory control.

Frontal Alpha Asymmetry in Children with Trauma Exposure

The purpose of the current study was to investigate differences in frontal alpha asymmetry (FAA) between children (5-17 years) with or without histories of trauma exposure. EEG data were obtained from 165 children who participated in the Healthy Brain Network Initiative during rest with eyes open and closed. FAA during resting-state electroencephalography was significantly more negative in the trauma-exposed group, suggesting greater left lateralized FAA and avoidance-oriented motivation. Moreover, alpha suppression (difference in alpha amplitude between eyes open and eyes closed conditions) was marginally greater in the trauma-exposed group. The results suggest that early exposure to trauma may be associated with trait-level avoidance of environmental stimuli, which ultimately may be predictive of psychopathology, including posttraumatic stress disorder (PTSD). Study findings thus provide preliminary evidence of brain-based mechanisms that may confer risk for PTSD in the wake of early trauma exposure.

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.

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.

A Systematic Review of the Effect of Parental Adverse Childhood Experiences on Parenting and Child Psychopathology

Adverse childhood experiences (ACEs) are defined as early exposure to maltreatment and household dysfunction. Researchers have demonstrated the link between ACEs and negative psychological, behavioral, interpersonal, and health outcomes. A growing area of interest in the ACE literature concerns the relationship between ACEs, parenting, and child psychopathology due to the intergenerational effect of ACEs. Emotional availability and discipline strategies are two domains of parenting that can increase understanding of the associations between ACEs, parenting, and child psychopathology from an attachment framework because they are both salient during early childhood and directly influence a child's later behavior. This paper utilized the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to elucidate the relationships between parental ACEs, parents' emotional availability and discipline strategies, and children's psychopathology. PubMed, PSYCINFO, and Psychology and Behavioral Sciences Collection were used to access the literature on June 16, 2020, and 26 studies met the inclusion criteria. Results from this review suggested that there is a direct association between ACEs and parental emotional availability and discipline techniques. Depression and dissociation were identified as potential mediators. There was support for the direct association between parental ACEs and children's internalizing and externalizing difficulties. Maternal anxiety and depressive symptoms, emotional availability, attachment, and children's maltreatment experiences were found to be possible mediators. Recommendations are proposed to address limitations within the literature to further expand upon the research of ACEs, parenting, and child psychopathology.

Maternal History of Adverse Experiences and Posttraumatic Stress Disorder Symptoms Impact Toddlers’ Early Socioemotional Wellbeing: The Benefits of Infant Mental Health-Home Visiting

Background

The present study examined the efficacy of the Michigan Model of Infant Mental Health-Home Visiting (IMH-HV) infant mental health treatment to promote the socioemotional wellbeing of infants and young children. Science illuminates the role of parental “co-regulation” of infant emotion as a pathway to young children’s capacity for self-regulation. The synchrony of parent–infant interaction begins to shape the infant’s own nascent regulatory capacities. Parents with a history of childhood adversity, such as maltreatment or witnessing family violence, and who struggle with symptoms of post-traumatic stress may have greater challenges in co-regulating their infant, thus increasing the risk of their children exhibiting social and emotional problems such as anxiety, aggression, and depression. Early intervention that targets the infant–parent relationship may help buffer the effect of parental risk on child outcomes.

Methods

Participants were 58 mother–infant/toddler dyads enrolled in a longitudinal randomized control trial testing the efficacy of the relationship-based IMH-HV treatment model. Families were eligible based on child age (<24 months at enrollment) and endorsement of at least two of four socio-demographic factors commonly endorsed in community mental health settings: elevated depression symptoms, three or more Adverse Childhood Experiences (ACEs) parenting stress, and/or child behavior or development concerns. This study included dyads whose children were born at the time of study enrollment and completed 12-month post-baseline follow-up visits. Parents reported on their own history of ACEs and current posttraumatic stress disorder (PTSD) symptoms, as well as their toddler’s socioemotional development (e.g., empathy, prosocial skills, aggression, anxiety, prolonged tantrums).

Results

Maternal ACEs predicted more toddler emotional problems through their effect on maternal PTSD symptoms. Parents who received IMH-HV treatment reported more positive toddler socioemotional wellbeing at follow-up relative to the control condition. The most positive socioemotional outcomes were for toddlers of mothers with low to moderate PTSD symptoms who received IMH-HV treatment.

Conclusion

Results indicate the efficacy of IMH-HV services in promoting more optimal child socioemotional wellbeing even when mothers reported mild to moderate PTSD symptoms. Results also highlight the need to assess parental trauma when infants and young children present with socioemotional difficulties.

Impact of maternal childhood trauma on child behavioral problems: The role of child frontal alpha asymmetry

Childhood trauma is associated with many long-term negative outcomes, and is not limited to the individual experiencing the trauma, but extends to subsequent generations. However, mechanisms underlying the association between maternal childhood trauma and child psychopathology are not well understood. Here, we targeted frontal alpha asymmetry (FAA) as a potential underlying factor of the relationship between maternal childhood trauma and child behavioral problems. Electroencephalography (EEG) was recorded from (N = 45) children (Mean age = 57.9 months, SD = 3.13) during an eyes-closed paradigm in order to evaluate FAA. Mothers reported on their childhood trauma experiences using the Childhood Trauma Questionnaire (CTQ), and on their child's behavior using the child behavior checklist (CBCL). We found that maternal childhood trauma significantly predicted child total, internalizing, and externalizing behavior at age 5 years. We also observed a role for FAA such that it acted as a moderator, but not mediator, for behavioral problems. We found that children with relative more right/less left frontal activity were more at risk to develop behavioral problems when their mother had been exposed to trauma in her childhood. These results indicate that child frontal asymmetry may serve as a susceptibility marker for child behavioral problems.
