Relative contribution of maternal adverse childhood experiences to understanding children's externalizing and internalizing behaviours at age 5: findings from the All Our Families cohort

Psychological Interventions and Those With Elements of Positive Psychology for Child and Youth Mental Health During the COVID-19 Pandemic: Literature Review, Lessons Learned, and Areas for Future Knowledge Dissemination

BACKGROUND

There was a marked decline in child and teenage mental health worldwide during the pandemic, with increasing prevalence of depression, anxiety, and suicide. Research indicates that positive psychological interventions may be beneficial for mental health.

OBJECTIVE

The aims of this review were to evaluate positive psychological interventions for child and youth mental health implemented during the COVID-19 pandemic and assess overall effectiveness for mental health and knowledge.

METHODS

We undertook a literature search of PubMed, MEDLINE, and Google Scholar for all eligible studies on digital and hybrid in-person psychological interventions for youth mental health during the COVID-19 pandemic. A particular emphasis was placed on positive psychological interventions or interventions that had components of positive psychology, including gratitude, acceptance, positive emotions, or resilience building.

RESULTS

A total of 41 interventions were included in this review. Most of the interventions were digital. Overall, most of the interventions assisted with one or more mental health or psychological indicators, such as depression, anxiety, posttraumatic stress disorder, stress, and resilience. However, findings were mixed when it came to targeting both depression and anxiety together. The interventions that promoted youth mental health most often had a range of diverse positive psychology components and were evidence based. Not all studies measured changes in mindfulness. Few studies examined knowledge acquired on mental health self-care, managing mental health problems, knowledge of positive psychological techniques, mindfulness knowledge, or mental health self-efficacy.

CONCLUSIONS

Diverse multicomponent interventions appear to assist with youth mental health overall, although their effects on both depression and anxiety are less clear. There is also a need for more research on knowledge gains to determine whether the interventions improved knowledge on mental health-supportive behaviors, which may be sustained beyond the intervention. Finally, more studies need to evaluate whether the interventions assisted with increasing self-efficacy for practicing positive psychological techniques as well as changes in mindfulness levels. Future studies should not only assess effectiveness for mental health outcomes but also assess knowledge translation, with valid measures of knowledge and self-efficacy for mental health-supportive behaviors and positive psychological skills acquired (eg, the ability to practice mindfulness).

Maternal adverse childhood experiences, child resilience factors, and child mental health problems: A multi-wave study

BACKGROUND

Research suggests that maternal ACEs have intergenerational consequences for offspring mental health. However, very few studies have investigated moderators of this association.

OBJECTIVES

The objective of this longitudinal study was to examine whether child resilience factors moderated the association between maternal ACEs prior to age 18, and child-reported symptoms of anxiety, depression, hyperactivity, and inattention.

PARTICIPANTS AND SETTING

The current study used data from 910 mother-child dyads. Participants were recruited in pregnancy from 2008 to 2010 as part of a longitudinal cohort study.

METHODS

Mothers had previously completed an ACEs questionnaire and reported on their child's resilience factors at child age 8-years. Children completed questionnaires about their mental health problems (symptoms of anxiety, depression, hyperactivity, and attention problems) at ages 10 and 10.5 years. Four moderation models were performed in total.

RESULTS

Results revealed that maternal ACEs predicted child-reported symptoms of anxiety (β = 0.174, p = .02) and depression (β = 0.37, p = .004). However, both these associations were moderated by higher levels of perceived child resilience factors (β = -0.29, p = .02, β = -0.33, p = .008, respectively). Specifically, there was no association between maternal ACEs and child mental health problems in the context of moderate and high levels of child resilience factors.

CONCLUSIONS

Children who have the ability to solicit support from internal and external sources (e.g., being creative, setting realistic goals, making friends easily) may be buffered against the consequences of maternal ACEs on anxiety and depression. Thus, the effects of maternal ACEs on child mental health problems are not deterministic.

Maternal childhood trauma and observed maternal care behaviors with 4-month-old infants

OBJECTIVE

To examine the relationship between maternal childhood trauma and early maternal caregiving behaviors (MCB).

METHOD

Participants included 74 mother-infant dyads (maternal age 20-45 years; ethnicity 64.9% Latina) from a longitudinal pregnancy cohort study. Maternal childhood trauma was assessed during pregnancy with the childhood trauma questionnaire (CTQ). Observed mother-infant interactions at infant age 4 months were coded utilizing modified Ainsworth's MCB rating scales that assessed a range of behaviors (e.g., acceptance, soothing, and delight) which we analyze grouped together and will summarize using the term "maternal sensitivity." Linear regressions tested the associations between maternal childhood trauma and MCB. Primary analyses examined the relationships of MCB with (a) any maternal childhood trauma (moderate or greater exposure to physical abuse, sexual abuse, emotional abuse, physical neglect, and/or emotional neglect) and (b) cumulative childhood trauma. Secondary analyses examined the relationships between each type of childhood trauma and MCB.

RESULTS

Exposure to childhood trauma was not associated with MCB (p = .88). Cumulative childhood trauma score was associated with lower scores on MCB (β = -1.88, p < .05). Emotional abuse and emotional neglect were individually associated with lower scores on MCB (β = -1.78, p = .04; β = -1.55, p = .04, respectively). Physical abuse, sexual abuse, and physical neglect were not associated with MCB.

CONCLUSIONS

Many mothers exposed to childhood trauma may be resilient to negative effects on parenting behaviors, while specific experiences of childhood trauma (emotional abuse, emotional neglect, and cumulative childhood trauma) may predict less sensitive early parenting behaviors.

A Short Adverse Experiences Measure Among Mothers of Young Children

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Maternal and Paternal Adverse Childhood Experiences (ACEs) and Offspring Health and Wellbeing: A Scoping Review

BACKGROUND

Adverse childhood experiences (ACEs) are common, often co-occur, and are associated with poor health outcomes across the life course. Emerging research has emphasized the lasting consequences of ACEs across generations, suggesting parental ACEs are associated with poor physical and mental health outcomes in children. However, the individual effects of fathers' ACEs and pathways of transmission remain unclear. A scoping review was conducted to summarize the current knowledgebase of the intergenerational consequences of parental ACEs on offspring health, clarify pathways of transmission, understand how ACEs are operationalized in the intergenerational literature, and identify gaps in knowledge.

METHODS

Six electronic databases were searched for articles published in English from 1995 to 2022 relating to the long-term consequences of parental ACEs on offspring physical and mental health. Articles underwent title, abstract, and full-text review by two investigators. Content analysis was performed to integrate findings across the included studies.

RESULTS

The search yielded 14,542 unique articles; 49 met the inclusion criteria. Thirty-six articles focused exclusively on mothers, one solely on fathers, and 12 included both mothers and fathers in their analyses. Six studies used an expanded definition of ACEs. Both direct and indirect associations between parental ACEs and poor offspring outcomes were identified, primarily through biological and psychosocial pathways.

CONCLUSIONS

Findings underscore the importance and oversight of fathers and the need to solidify a unified definition and measure of ACEs. This review identified modifiable protective factors (social support, father involvement) and pathways of transmission (parental mental health, parenting); both having important implications for intervention development.

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.

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

OBJECTIVE

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

PARTICIPANTS AND SETTING

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

The relationship between parental adverse childhood experiences and the health, well-being and development outcomes of their children: a systematic review

OBJECTIVES

A growing body of research is emerging regarding the relationship between parental adverse childhood experiences (ACEs) and negative health, well-being and developmental outcomes in their children. This systematic review seeks to understand the relationship between parental ACEs and the health, well-being and developmental outcomes of their children and whether the relationships differ according to the number and type of parental ACEs.

STUDY DESIGN

Systematic review.

METHOD

The review includes articles published between 2000 and 2021 from studies using quantitative longitudinal methods and multivariate analysis to investigate the relationship between parental ACEs and their offspring's outcomes. Relevant studies were identified through a systematic search of five databases and findings synthesised using a narrative synthesis. This review was registered on PROSPERO (CRD42021274068).

RESULTS

Nineteen studies met the inclusion criteria and were included in the review. This resulted in a combined population sample of 124,043 parents and 128,400 children. Diversity in measurement of parental ACE exposure and in the type of ACEs measured within the studies precluded a meta-analysis. Offspring of parents exposed to ACEs had a higher risk of a range of negative health, well-being and developmental outcomes. This relationship differs according to the number and type of parental ACEs, with a positive relationship observed between the number of parental ACEs and the risk of negative health, well-being and development outcomes in their children.

CONCLUSIONS

These findings indicate that screening for parental ACEs by health visitors, midwives and other health or social care staff may identify an at-risk population of infants, children and adolescents and improve child outcomes.

Women's Mental Health up to Eight Years after Childbirth and Associated Risk Factors: Longitudinal Findings from the All Our Families Cohort in Canada

OBJECTIVE

This study examined the prevalence of elevated maternal anxiety and/or depression symptoms up to eight years after childbirth and the association between role and relationship strains during parenting and mental health challenges from three to eight years after childbirth.

METHODS

This study used data from the All Our Families longitudinal pregnancy cohort. Role and relationship strain factors and anxiety and depression symptoms were measured at repeated time points from four months to eight years after childbirth. The proportion of women with elevated anxiety and/or depression was calculated at each available time point. Generalized estimating equation models were used to examine the association between role and relationship strain factors and anxiety and/or depression from three to eight years after childbirth. Predicted probability of having anxiety and/or depression was estimated across those with and without challenges with roles and relationships. The models were adjusted for known risk factors such as maternal income and perinatal anxiety and/or depression.

RESULTS

The prevalence of elevated anxiety and/or depression ranged from 18.8% (at four months) to 26.2% (at eight years). The adjusted odds ratio of anxiety and/or depression was 3.5 (95% CI = 2.9, 4.3) for those juggling family responsibilities and 2.4 (95% CI = 2.0, 3.0) for those with stressful partner relationship compared to their counterparts. Similarly, experiencing financial crunch and poor partner relationship were associated with increased mental health difficulties. Women without challenges in roles or relationships had a 23% lower predicted probability of anxiety and/or depression than those with the challenges.

CONCLUSIONS

Monitoring mothers for anxiety and depression beyond the postpartum period and strategies that address role and relationship challenges may be valuable to women at risk of anxiety and depression.

Associations of Maternal Adverse Childhood Experiences with Behavioral Problems in Preschool Children

Investigations have found maternal adverse childhood experiences (ACEs) cause an intergenerational danger to their children's health. However, no study has investigated the effects of maternal ACEs on behavioral problems of preschool children in China and gender differences on these effects. This paper aims to investigate the role of maternal ACEs on behavioral problems of preschool children in China and explore gender differences as related to these behavioral problems. Stratified cluster sampling method was used to select 7318 preschool children from 12 districts in Hefei city, China. A questionnaire survey was conducted to collect information on maternal exposure to ACEs and Conners' Parent Rating Scales. Logistic regression was used to analyze the relationship between maternal ACEs and children's behavioral problems. The prevalence of behavioral problems in preschool children was 16.0%, while it was higher among girls (18.4%) than boys (13.92%) (χ² = 27.979, p < 0.001). The rate of behavioral problems in children in the group of mothers with ACEs was higher than those without ACEs (all p < 0.05). Maternal ACEs were associated with increased risk of the behavior problems in preschool children (adjusted OR 2.91, 95% CI 2.45-3.45), and no gender difference (in girls 3.01, 2.38-3.81, in boys 2.79, 2.17-3.58, respectively) was found. Maternal ACEs were associated with increased risk of each type of the behavioral problems of preschool children, except that maternal emotional neglect was not associated with psycho-physical problems, impulse-activities, and anxiety. The only gender differences found were higher conduct problems related to maternal emotional abuse and ACEs and higher anxiety related to maternal physical abuse and community violence in girls compared with boys. Mothers exposured to ACEs are more likely to have children with behavioral health problems in preschool period. Further research is needed to explore the mechanisms by which maternal ACEs influence children's behavioral problems.

Maternal attachment insecurity, maltreatment history, and depressive symptoms are associated with broad DNA methylation signatures in infants

The early environment, including maternal characteristics, provides many cues to young organisms that shape their long-term physical and mental health. Identifying the earliest molecular events that precede observable developmental outcomes could help identify children in need of support prior to the onset of physical and mental health difficulties. In this study, we examined whether mothers' attachment insecurity, maltreatment history, and depressive symptoms were associated with alterations in DNA methylation patterns in their infants, and whether these correlates in the infant epigenome were associated with socioemotional and behavioral functioning in toddlerhood. We recruited 156 women oversampled for histories of depression, who completed psychiatric interviews and depression screening during pregnancy, then provided follow-up behavioral data on their children at 18 months. Buccal cell DNA was obtained from 32 of their infants for a large-scale analysis of methylation patterns across 5 × 106 individual CpG dinucleotides, using clustering-based significance criteria to control for multiple comparisons. We found that tens of thousands of individual infant CpGs were alternatively methylated in association with maternal attachment insecurity, maltreatment in childhood, and antenatal and postpartum depressive symptoms, including genes implicated in developmental patterning, cell-cell communication, hormonal regulation, immune function/inflammatory response, and neurotransmission. Density of DNA methylation at selected genes from the result set was also significantly associated with toddler socioemotional and behavioral problems. This is the first report to identify novel regions of the human infant genome at which DNA methylation patterns are associated longitudinally both with maternal characteristics and with offspring socioemotional and behavioral problems in toddlerhood.

Adverse Childhood Experiences in Autistic Children and Their Caregivers: Examining Intergenerational Continuity

Although there is an urgent need to develop trauma-informed services for autistic youth, little research has evaluated adverse childhood experiences (ACEs) in autistic youth from an intergenerational perspective. 242 caregivers of autistic (n = 117) and non-autistic (n = 125) youth reported on ACEs that they experienced in their own childhoods and ACEs experienced by their children, as well as measures of depression, stress, and child autistic traits and behavioral concerns. Autistic youth and their caregivers both experienced significantly higher rates of ACEs than the non-autistic dyads. Intergenerational continuity, the association between caregiver and child ACEs, was significantly stronger for autistic youth. ACEs showed differential patterns of associations with parent depressive symptoms and child autistic traits across groups.

Intergenerational trauma: Parental PTSD and parent-reported child abuse subtypes differentially relate to admission characteristics in the autism inpatient collection

Autistic youth experience high rates of maltreatment. Little research has considered how distinct abuse dimensions differentially relate to meaningful outcomes, nor taken an intergenerational approach to consider how caregiver trauma and child maltreatment are related. This study sought to identify how parent-reported child abuse subtypes and parent posttraumatic stress disorder (PTSD) relate to each other and to admission characteristics upon inpatient service entry. Autistic youth (N = 527; 79% White, 21.3% girls, mean age = 12.94 years) participated in the autism inpatient collection. Parents reported on child abuse subtypes (physical, sexual, emotional) and their own PTSD, child behavior and emergency services, and parenting stress. Youth of parents with PTSD were nearly three times more likely to have parent-reported physical and emotional abuse. Autistic girls were more likely to experience parent-reported sexual abuse and a higher number of subtypes. Lower income related to higher rates of parent-reported child emotional abuse and parent PTSD. Emotional abuse associated with child behavior whereas both child physical and emotional abuse related to emergency services. Reported parent PTSD associated with child behavior and parental distress. When considered jointly, parent PTSD and number of parent-reported child abuse subtypes differentially related to child behavior and interacted to predict psychiatric hospitalizations. Intergenerational continuity of trauma is important to consider among autistic youth, and both parent-reported child abuse and parent PTSD relate to admission characteristics. Critical limitations include reliance on binary parent reports of child abuse and parent PTSD and the low representation of youth of minoritized identities. Implications for trauma-informed care are discussed.

Maternal depressive and anxiety symptoms before and during the COVID-19 pandemic in Canada: a longitudinal analysis

BACKGROUND

Parents have faced substantial social and economic challenges during the COVID-19 pandemic. Preliminary cross-sectional research has demonstrated increases in mental health problems in mothers during the COVID-19 pandemic compared with pre-pandemic estimates. We aimed to study an existing longitudinal cohort of mothers to assess changes in the prevalence of maternal depression and anxiety symptoms as a result of the COVID-19 pandemic over time and at the individual level.

METHODS

In this longitudinal observational study, women who took part in the All Our Families pregnancy cohort in Canada were invited to complete a COVID-19 impact survey between May 20 and July 15, 2020. Women who had not agreed to additional research, had discontinued, were lost to follow-up, or who were not contactable via email were excluded. Maternal depression and anxiety symptoms during the COVID-19 pandemic were compared with three previous estimates collected at 3, 5, and 8-year timepoints (between April, 2012, and October, 2019). Depression symptoms were assessed using the 10-item Center for Epidemiological Studies Depression scale and anxiety symptoms were assessed using the short form of the Spielberger State-Trait Anxiety Inventory. Repeated cross-sectional analyses were done to assess temporal trends and fixed-effects regression models were fitted to assess within-person change over time.

FINDINGS

Of the 3387 women included in the All Our Families study, 2445 women were eligible and were invited to participate in the COVID-19 impact study, of whom 1333 consented to participate, and 1301 were included in the longitudinal analysis. At the COVID-19 impact survey timepoint, a higher proportion of mothers had clinically significant depression (35·21%, 95% CI 32·48-38·04) and anxiety symptoms (31·39%, 28·76-34·15) than at all previous data collection timepoints. The mean depression score (8·31, 95% CI 7·97-8·65) and anxiety score (11·90, 11·66-12·13) at the COVID-19 pandemic timepoint were higher than previous data collection waves at the 3-year timepoint (mean depression score 5·05, 4·85-5·25; mean anxiety score 9·51, 9·35-9·66), 5-year timepoint (mean depression score 5·43, 5·20-5·66; mean anxiety score 9·49, 9·33-9·65), and 8-year timepoint (mean depression score 5·79, 5·55-6·02; mean anxiety score 10·26, 10·10-10·42). For the within-person comparisons, depression scores were a mean of 2·30 points (95% CI 1·95-2·65) higher and anxiety scores were a mean of 1·04 points (0·65-1·43) higher at the COVID-19 pandemic timepoint, after controlling for time trends. Larger increases in depression and anxiety symptoms were observed for women who had income disruptions, difficulty balancing home schooling with work responsibilities, and those with difficulty obtaining childcare. White mothers had greater increases in anxiety scores than non-white mothers and health-care workers had smaller increases in depressive symptoms than non-health-care workers.

INTERPRETATION

Compared with previous estimates, the prevalence of maternal depression and anxiety among mothers in a Canadian cohort increased during the COVID-19 pandemic. Financial support, childcare provision, and avoiding the closure of schools, might be key priorities for preventing future increases in maternal psychological distress.

Adverse childhood experiences are associated with illicit drug use among pregnant women with middle to high socioeconomic status: findings from the All Our Families Cohort

Background

Adverse childhood experiences (ACEs) are associated with illicit drug use among pregnant women who are socioeconomically vulnerable. While it is assumed that the impact of ACEs on illicit drug use in pregnancy is reduced among women with higher socioeconomic status (SES), this assumption is not well tested in the literature. The objective of this study was to examine the impact of maternal ACEs on illicit drug use in a community-based sample of pregnant women with middle to high SES.

Methods

This study is a secondary analysis of a prospective cohort study that collected data from 1660 women during and after pregnancy in Calgary, Canada between 2008 and 2011 using mailed surveys. Illicit drug use in pregnancy was self-reported by women at 34–36 weeks gestation. An established scale examined maternal ACEs before 18 years. Logistic regression models and 95% confidence intervals tested associations between maternal ACE scores and illicit drug use in pregnancy.

Results

Overall, 3.1% of women in this predominantly married, well-educated, middle and upper middle income sample reported illicit drug use in pregnancy. Women with 2–3 ACEs had more than a two-fold increase, and women with 4 or more ACEs had almost a four-fold increase in illicit drug use in pregnancy, relative to women with 0–1 ACEs after adjustment for confounders. Exposure to child abuse was more consistently associated with illicit drug use in pregnancy than exposure to household dysfunction in childhood.

Conclusions

Maternal ACEs were common and associated with a moderate increase in the odds of illicit drug use in pregnancy among Canadian women with middle to high SES.
