Beyond Cumulative Risk: A Dimensional Approach to Childhood Adversity

Adverse Childhood Experiences and Health Outcomes Among Transition-Age Autistic Youth

BACKGROUND

Adverse childhood experiences (ACEs) have been associated with poor health outcomes in the general population. However, their impact on autistic youth remains unclear.

OBJECTIVE

The primary objective was to understand how childhood adversity is related to the general health, mental health, and physical health of transition-age autistic youth.

PARTICIPANTS AND SETTING

Using data from the 2018-2021 National Survey of Children's Health, this cross-sectional study involved 2056 autistic youth aged 12-17.

METHODS

Logistic regression was employed to test the association between three measures of ACEs - individual ACEs, cumulative ACEs, and grouped ACEs based on contexts, and health outcomes of autistic youth.

RESULTS

Our study observed a high prevalence of ACEs among autistic youth, with a substantially higher proportion experiencing multiple ACEs than their neurotypical peers. Individual ACEs were significantly associated with specific health issues. Cumulative ACEs demonstrated a clear dose-response relationship with health outcomes, with higher ACE counts increasing the likelihood of experiencing poor general health, mental health conditions, and physical health issues. Moreover, grouped ACEs associated with health differently, with community-based ACEs being particularly linked to general health status, mental health conditions, and physical health conditions, while family-based ACEs correlated more with more severe mental health conditions and being overweight.

CONCLUSION

These findings collectively emphasize the importance of addressing ACEs as a public health concern among transition-age autistic youth, highlighting the need for targeted interventions, prevention strategies, and support services to mitigate the negative impact of ACEs on the overall well-being of this growing community.

Lifetime Polyvictimization and Mental Health Outcomes in Women With vs Without Incarceration Histories: A Population-Based Latent Class Analysis

We use latent class analysis, a life course framework, and information on the type, frequency, and timing of trauma exposure to identify distinct polytrauma groups in a national sample of women (AddHealth). We compare the identified polytrauma groups and their associations with mental health in adulthood in women with and without incarceration histories. A unique group with polyvictimization (neglect, physical, sexual) exposure in childhood by a caregiver in women with incarceration histories was not identified in women without incarceration histories. We find evidence of distinct associations between polytrauma groups and mental health and possibly, criminal justice involvement, in adulthood.

Risk and resilience factors for psychopathology during pregnancy: An application of the Hierarchical Taxonomy of Psychopathology (HiTOP)

Pregnancy is a time of increased vulnerability to psychopathology, yet limited work has investigated the extent to which variation in psychopathology during pregnancy is shared and unshared across syndromes and symptoms. Understanding the structure of psychopathology during pregnancy, including associations with childhood experiences, may elucidate risk and resilience factors that are transdiagnostic and/or specific to particular psychopathology phenotypes. Participants were 292 pregnant individuals assessed using multiple measures of psychopathology. Confirmatory factor analyses found evidence for a structure of psychopathology consistent with the Hierarchical Taxonomy of Psychopathology (HiTOP). A common transdiagnostic factor accounted for most variation in psychopathology, and both adverse and benevolent childhood experiences (ACEs and BCEs) were associated with this transdiagnostic factor. Furthermore, pregnancy-specific anxiety symptoms most closely reflected the dimension of Fear, which may suggest shared variation with manifestations of fear that are not pregnancy-specific. ACEs and BCEs also linked to specific prenatal psychopathology involving thought problems, detachment, and internalizing, externalizing, antagonistic, and antisocial behavior. These findings extend the dimensional and hierarchical HiTOP model to pregnant individuals and show how maternal childhood risk and resilience factors relate to common and specific forms of psychopathology during pregnancy as a period of enhanced vulnerability.

Childhood trauma is associated with early-onset but not late-onset suicidal behavior in late-life depression

OBJECTIVES

To examine the relationship between childhood traumatic experiences and early and late-onset suicidal behavior among depressed older adults.

DESIGN

Cross-sectional study.

SETTING

Inpatient and outpatient psychiatric services in Pennsylvania.

PARTICIPANTS

Our sample included 224 adults aged 50+ (M ± SD = 62.5 ± 7.4) recruited into three depressed groups: (1) 84 suicide attempters, (2) 44 suicide ideators, and (3) 58 non-suicidal comparisons, and a non-psychiatric healthy comparison group (N = 38).

MEASUREMENTS

The Childhood Trauma Questionnaire measured experiences of childhood trauma such as emotional abuse, physical abuse, emotional neglect, physical neglect, and sexual abuse.

RESULTS

Attempters were separated into early- and late-onset based on age of first attempt using a statistical algorithm that identified a cutoff age of 30 years old. Overall, we found group differences in emotional and physical abuse and neglect in both genders and sexual abuse in females, but not in males. Early-onset attempters experienced more childhood emotional abuse and neglect than late-onset attempters and were more likely to have experienced multiple forms of abuse. They also experienced more emotional abuse and neglect than all comparison groups. Consistently, early-onset attempters more often met criteria for current or lifetime PTSD relative to late-onset attempters and most comparison groups. Late-onset attempters had similar levels of childhood trauma as other depressed groups.

CONCLUSIONS

Our study reaffirms that there are distinct pathways to suicidal behavior in older adults based on their age of first suicide attempt and that trauma experienced in childhood has long-lasting emotional and behavioral consequences, even into late life.

The acute effects of community violence on young children's regulatory, behavioral, and developmental outcomes in a low-income urban sample in Brazil

BACKGROUND

Existing research on the impacts of adversity on young children's psychological well-being has largely focused on household-level risk factors using observational methods in high-income countries. This study leverages natural variation in the timing and location of community homicides to estimate their acute effects on the regulatory, behavioral, and developmental outcomes of Brazilian 3-year-olds.

METHODS

We compared the outcomes of children who were assessed soon after a recent neighborhood homicide to those of children from the same residential neighborhoods who had not recently experienced community violence. Our sample included 3,241 3-year-olds (Mage = 41.05 months; 53% female; 45% caregiver education less than middle school; 26% receiving a public assistance program) from seven neighborhoods in São Paulo, Brazil. Child outcome measures included parent reports of effortful control and behavior problems as well as direct assessments of children's developmental (cognitive, language, and motor) skills. Community homicides were measured using police records.

RESULTS

Recent exposure to community homicides was associated with lower effortful control, higher behavior problems, and lower overall developmental performance for children (d = .05-.20 standard deviations; p = ns - <.001). Effects were consistent across subgroups based on sociodemographic characteristics and environmental supports, but generally largest when community violence exposure was geographically proximal (within 600 m of home) and recent (within 2 weeks prior to assessment).

CONCLUSIONS

Results highlight the pervasive effects that community violence can have on young children as well as the need to expand support to mitigate these effects and prevent inequities early in life.

Acculturation Stress Magnifies Child Depression Effect of Stressful Life Events for Latinx Youth 3 Years Later

Introduction

Experiences of stressful life events (SLEs) during childhood are associated with greater risk for youth psychopathology. Although SLEs are reported in greater frequency by Latinx families, Latinx populations remain largely absent in the SLE literature. Furthermore, Latinx populations face added stressors related to socio-political climate, acculturation, and racism and discrimination. The purpose of this study was to explore the intersection between parent-reported SLEs and acculturation (i.e., socio-political climate-related) stressors for Latinx youth. Greater frequency of caregiver reported SLEs were hypothesized to predict higher depressive symptoms in their children three years later, and acculturation stress was hypothesized to amplify these effects.

Method

The community-recruited, low-income sample for this study consisted of 198 Latinx caregivers (98.5% mothers, 77.3% foreign-born) and their children (M age = 7.4, 47.5% female). Study hypotheses were tested using MPlus.

Results

Consistent with prior literature, more SLEs reported at age 7 by parents were associated with more child-reported depressive symptoms at age 10 but only among boys. However, for both boys and girls, there was a significant interaction between acculturation stress and family SLEs. Specifically, as the amount of acculturation stress reported at age 7 increased, the negative impact of family SLEs on child-reported depressive symptoms at age 10 was magnified, regardless of gender.

Conclusion

Adding to the literature on SLEs within Latinx families, these results indicate that acculturation and socio-political climate stressors need be considered in discussions of the effects of life stress on Latinx youth and their families.

Recent Stressful Life Events and Perceived Stress as Serial Mediators of the Association between Adverse Childhood Events and Insomnia

Insomnia is common in college students and linked to poorer mental and physical health. There is growing evidence that adverse childhood experiences (ACEs) may contribute to insomnia in adulthood. However, beyond the need for additional replication of these findings, there is a need to identify underlying mechanisms that plausibly connect the two experiences. Based on a serial mediation model, the current study examined the role of two theoretically informed mediators: recent stressful life events and perceived stress. A cross-sectional survey of 2,218 college students at a large university in the southwestern United States was conducted between August 2020 and December 2021. The sample was predominantly Hispanic (96%) and female (73%), with a mean age of 20.7 years. Standardized measures of adverse childhood experiences, recent stressful life events, perceived stress, and insomnia were administered to participants online. Almost 20% of participants reported having experienced four or more adverse childhood experiences and 63% met the threshold for insomnia. Reporting four or more ACEs was associated with significantly greater insomnia severity, and this relationship was serially mediated by both recent stressful life events and perceived stress. However, recent stressful life events appeared to be the most powerful mediator. The results of the current study indicate that recent exposure to stressful life events serves as a plausible mechanism linking early adversity during childhood to adult insomnia and could therefore serve as a potential target for intervention. The findings suggest that students would benefit from university-wide efforts to reduce the number and/or intensity of common stressors.

Early life adversity is associated with greater similarity in neural representations of ambiguous and threatening stimuli

Exposure to early life adversity (ELA) is hypothesized to sensitize threat-responsive neural circuitry. This may lead individuals to overestimate threat in the face of ambiguity, a cognitive-behavioral phenotype linked to poor mental health. The tendency to process ambiguity as threatening may stem from difficulty distinguishing between ambiguous and threatening stimuli. However, it is unknown how exposure to ELA relates to neural representations of ambiguous and threatening stimuli, or how processing of ambiguity following ELA relates to psychosocial functioning. The current fMRI study examined multivariate representations of threatening and ambiguous social cues in 41 emerging adults (aged 18 to 19 years). Using representational similarity analysis, we assessed neural representations of ambiguous and threatening images within affective neural circuitry and tested whether similarity in these representations varied by ELA exposure. Greater exposure to ELA was associated with greater similarity in neural representations of ambiguous and threatening images. Moreover, individual differences in processing ambiguity related to global functioning, an association that varied as a function of ELA. By evidencing reduced neural differentiation between ambiguous and threatening cues in ELA-exposed emerging adults and linking behavioral responses to ambiguity to psychosocial wellbeing, these findings have important implications for future intervention work in at-risk, ELA-exposed populations.

Do dimensions of childhood adversity differ in their direct associations with youth psychopathology? A meta-analysis

Growing evidence supports the unique pathways by which threat and deprivation, two core dimensions of adversity, confer risk for youth psychopathology. However, the extent to which these dimensions differ in their direct associations with youth psychopathology remains unclear. The primary aim of this preregistered meta-analysis was to synthesize the associations between threat, deprivation, internalizing, externalizing, and trauma-specific psychopathology. Because threat is proposed to be directly linked with socioemotional development, we hypothesized that the magnitude of associations between threat and psychopathology would be larger than those with deprivation. We conducted a search for peer-reviewed articles in English using PubMed and PsycINFO databases through August 2022. Studies that assessed both threat and deprivation and used previously validated measures of youth psychopathology were included. One hundred and twenty-seven articles were included in the synthesis (N = 163,767). Results of our three-level meta-analyses indicated that adversity dimension significantly moderated the associations between adversity and psychopathology, such that the magnitude of effects for threat (r's = .21-26) were consistently larger than those for deprivation (r's = .16-.19). These differences were more pronounced when accounting for the threat-deprivation correlation. Additional significant moderators included emotional abuse and youth self-report of adversity. Findings are consistent with the Dimensional Model of Adversity and Psychopathology, with clinical, research, and policy implications.

Childhood maltreatment and resting-state network connectivity: The risk-buffering role of positive parenting

Unraveling the neurobiological foundations of childhood maltreatment is important due to the persistent associations with adverse mental health outcomes. However, the mechanisms through which abuse and neglect disturb resting-state network connectivity remain elusive. Moreover, it remains unclear if positive parenting can mitigate the negative impact of childhood maltreatment on network connectivity. We analyzed a cohort of 194 adolescents and young adults (aged 14-25, 47.42% female) from the Neuroscience in Psychiatry Network (NSPN) to investigate the impact of childhood abuse and neglect on resting-state network connectivity. Specifically, we examined the SAN, DMN, FPN, DAN, and VAN over time. We also explored the moderating role of positive parenting. The results showed that childhood abuse was linked to stronger connectivity within the SAN and VAN, as well as between the DMN-DAN, DMN-VAN, DMN-SAN, SAN-DAN, FPN-DAN, SAN-VAN, and VAN-DAN networks about 18 months later. Positive parenting during childhood buffered the negative impact of childhood abuse on network connectivity. To our knowledge, this is the first study to demonstrate the protective effect of positive parenting on network connectivity following childhood abuse. These findings not only highlight the importance of positive parenting but also lead to a better understanding of the neurobiology and resilience mechanisms of childhood maltreatment.

The association between youth violence and mental health outcomes in Colombia: A cross sectional analysis

BACKGROUND

Violence against children and youth poses public health risks regarding mental health symptoms and substance use. Less studied is the relationship between violence and mental health/substance abuse in the Latin American context. This study explored sex-stratified relationships between violence and mental health/substance use among Colombian youth.

METHODS

We analyzed the 2018 Colombian Violence Against Children and Youth Survey, which collected cross-sectional data from Colombian youth (13-24 years) (n = 2705). Exposure variables were (i) binary sexual, emotional, and physical victimization and (ii) poly-victimization. The outcomes were binary suicidal thoughts, self-harm, past-month psychological distress, binge drinking, smoking, and drug use. Sex-stratified, logistic regressions were adjusted for age, primary school, parental presence, relationship status, and witnessing community violence.

RESULTS

For females, (i) emotional violence (compared to being unexposed) was associated with greater odds of suicidal thoughts, self-harm, and psychological distress and (ii) sexual violence was associated with suicidal thoughts and self-harm. For males, (i) emotional violence (compared to being unexposed) was associated with greater odds of suicidal thoughts and psychological distress, but not self-harm and (ii) sexual violence exposure was associated with suicidal thoughts and self-harm. Physical violence was generally not associated with internalized mental health outcomes for females/males, when emotional and sexual violence were held constant. Poly-victimization was consistently and positively associated with internalized mental health symptoms among females, and to a lesser degree for males. Substance use outcomes for males or females were not associated with violence.

CONCLUSIONS

Findings highlight the internalized mental health burden of emotional and sexual violence.

Individual and environmental factors in internalizing disorders in children and adolescents

BACKGROUND

Literature has emphasized the role of biopsychosocial factors in internalizing disorders; however, the role of developmental competencies of a child have not been explored much in this context. The current study aimed to understand the differences in developmental competencies, temperament, parenting practices and psychosocial adversities between children with and without internalizing disorders.

METHOD

The sample consisted of 200 children and adolescents aged seven to 18 years, with equal number of those with and without an internalizing disorder; and one of their parents. Psychopathology, temperament, interpersonal competence, emotion regulation, executive function, self-concept, adaptive behaviour, parenting practices, life events, family environment and abnormal psychosocial situations were measured using standardized tools.

FINDINGS

Discriminant analysis revealed that temperamental domains of sociability and rhythmicity, developmental competencies of adaptive behaviour and self-concept, parenting practices involving father's involvement and overall positive parenting differentiated the clinical and control groups better. Among psychosocial adversities, family environment domains of cohesion and organization, and subjective stress from life events and abnormal psychosocial situations were the most important discriminators.

CONCLUSION

The current study reveals that specific individual factors involving temperament and developmental competencies and environmental factors involving parenting practices and psychosocial adversities are significantly associated with internalizing disorders. This has implications for the mental health care of children and adolescents with internalizing disorders.

Commentary on the power of predictability: patterns of signals in early life shape neurodevelopment and mental health trajectories

As Davis and Glynn observe in the introduction to their review, early life adversity is a significant impediment to healthy child development. Whereas some theoretical accounts emphasize the sheer number of physical and psychosocial risk factors children experience (Evans, Li, & Whipple, Psychological Bulletin, 2013, 139, 1342), Davis and Glynn review a program of research that is aligned with models highlighting the types of adversity children encounter. They expand on accounts that differentiate threat from deprivation (McLaughlin & Sheridan, Current Directions in Psychological Science, 2016, 25, 239) to draw attention to the role of unpredictability in children's development.

An Examination of Sleep as a Mediator of the Relationship between Childhood Adversity and Depression in Hispanic and Non-Hispanic Young Adults

The current study integrates previous research on adverse childhood experiences (ACEs) and long-term health outcomes to examine associations between ACEs, sleep duration, and depression in a diverse, mostly healthy, sample of young adults. We examine whether sleep duration mediates the association between ACEs and depression among young adults, and whether ethnicity may moderate observed relationships between ACEs, sleep duration and depression. Data were collected from 518 young adults (66.8% female, Mage=19.79 years, SDage=3.43 years) enrolled in undergraduate Psychology courses at a large Southwestern university. Participants primarily reported their racial/ethnic background as Non-Hispanic White (60.6%) and Hispanic/Latino (25.1%). Participants self-reported their ACEs exposure, sleep characteristics, and depressive symptoms. In addition to calculating overall exposure to ACEs, scores for the specific dimensions of adversity were also calculated (Abuse, Neglect, Exposure to Violence). Results supported a mediation model whereby higher reports of ACEs were associated with depressive symptoms both directly and through sleep duration. Results were not moderated by ethnicity. Findings provide support for sleep duration as one potential pathway through which ACEs may be associated with depressive symptoms in young adulthood, and suggest that this pathway is similar in Hispanic and non-Hispanic young adults.

Strengthening through adversity: The hormesis model in developmental psychopathology

BACKGROUND

Employing a developmental psychopathology framework, we tested the utility of the hormesis model in examining the strengthening of children and youth through limited levels of adversity in relation to internalizing and externalizing outcomes within a brain-by-development context.

METHODS

Analyzing data from the Adolescent Brain and Cognitive Development study (N = 11,878), we formed latent factors of threat, deprivation, and unpredictability. We examined linear and nonlinear associations between adversity dimensions and youth psychopathology symptoms and how change of resting-state functional connectivity (rsFC) in the default mode network (DMN) from Time 1 to Time 5 moderates these associations.

RESULTS

A cubic association was found between threat and youth internalizing problems; low-to-moderate family conflict levels reduced these problems. Deprivation also displayed a cubic relation with youth externalizing problems, with moderate deprivation levels associated with fewer problems. Unpredictability linearly increased both problem types. Change in DMN rsFC significantly moderated the cubic link between threat levels and internalizing problems, with declining DMN rsFC levels from Time 1 to Time 5 facilitating hormesis. Hormetic effects peaked earlier, emphasizing the importance of sensitive periods and developmental timing of outcomes related to earlier experiences.

CONCLUSIONS

Strengthening through limited environmental adversity is crucial for developing human resilience. Understanding this process requires considering both linear and nonlinear adversity-psychopathology associations. Testing individual differences by brain and developmental context will inform preventive intervention programming.

Childhood adversity and psychopathology: the dimensions of timing, type and chronicity in a population-based sample of high-risk adolescents

BACKGROUND

Research on childhood adversity and psychopathology has begun investigating the dimension of timing, however the results have been contradictory depending on the study population, outcome and how adverse life events (ALEs) were operationalized. Additionally, studies so far typically focus only on a narrow range of psychiatric diagnoses or symptoms. The current cross-sectional study aimed to examine the association between timing, type and chronicity of ALEs and adolescent mental health problems.

METHODS

Adolescents from a population-based cohort oversampled on emotional and behavioral problems (mean age 14.8; range 12-17, N = 861) were included in the current analysis. Primary caregivers were interviewed on what ALEs adolescents experienced. ALEs were defined in two ways: (1) broad operationalization, including school difficulties, parental divorce, and family sickness; and (2) physically threatening abuse only, including physical and sexual violence. After looking at lifetime ALEs, we turned to chronicity, timing and sex differences. We focused on overall psychiatric symptoms as well as specific domains of emotional and behavioral problems, assessed using the Youth Self Report (YSR) and psychotic experiences assessed using the Prodromal Questionnaire-16 (PQ-16). A series of linear models adjusted for sociodemographic and parental factors were used.

RESULTS

Lifetime ALEs were associated with all types of psychopathology, with relatively bigger effect sizes for broad than for physical ALEs. The latter associations were found to be more robust to unmeasured confounding. The 9-12 age period of experiencing both broad and physical ALE's was most saliently associated with any psychopathology. Girls were more at risk after experiencing any ALEs, especially if the adversity was chronic or ALEs took place after the age of 12.

CONCLUSIONS

Broad as well as physical ALEs are associated with psychopathology, especially ALEs experienced during the 9-12 age period. Physical ALEs may be more useful in investigating specific etiological factors than broad ALEs. Sex differences may not emerge in lifetime measures of ALEs, but can be important for chronic and later childhood adversity.

Childhood adversity and accelerated reproductive events: a systematic review and meta-analysis

OBJECTIVE

Accelerated female reproductive events represent the early onset of reproductive events involving puberty, menarche, pregnancy loss, first sexual intercourse, first birth, parity, and menopause. This study aimed to explore the association between childhood adversity and accelerated female reproductive events.

DATA SOURCES

PubMed, Web of Science, and Embase were systematically searched from September 22, 2022 to September 23, 2022.

STUDY ELIGIBILITY CRITERIA

Observational cohort, cross-sectional, and case-control studies in human populations were included if they reported the time of reproductive events for female individuals with experience of childhood adversity and were published in English.

METHODS

Two reviewers independently screened studies, obtained data, and assessed study quality, and conflicts were resolved by a third reviewer. Dichotomous outcomes were evaluated using meta-analysis, and pooled odds ratios and 95% confidence intervals were generated using random-effects models. Moderation analysis and meta-regression were used to investigate heterogeneity.

RESULTS

In total, 21 cohort studies, 9 cross-sectional studies, and 3 case-control studies were identified. Overall, female individuals with childhood adversity were nearly 2 times more likely to report accelerated reproductive events than those with no adversity exposure (odds ratio, 1.91; 95% confidence interval, 1.33-2.76; I2=99.6%; P<.001). Moderation analysis indicated that effect sizes for the types of childhood adversity ranged from an odds ratio of 1.61 (95% confidence interval, 1.23-2.09) for low socioeconomic status to 2.13 (95% confidence interval, 1.14-3.99) for dysfunctional family dynamics. Among the 7 groups based on different reproductive events, including early onset of puberty, early menarche, early sexual initiation, teenage childbirth, preterm birth, pregnancy loss, and early menopause, early sexual initiation had a nonsignificant correlation with childhood adversity (odds ratio, 2.70; 95% confidence interval, 0.88-8.30; I2=99.9%; P<.001). Considerable heterogeneity (I2>75%) between estimates was observed for over half of the outcomes. Age, study type, and method of data collection could explain 35.9% of the variance.

CONCLUSION

The literature tentatively corroborates that female individuals who reported adverse events in childhood are more likely to experience accelerated reproductive events. This association is especially strong for exposure to abuse and dysfunctional family dynamics. However, the heterogeneity among studies was high, requiring caution in interpreting the findings and highlighting the need for further evaluation of the types and timing of childhood events that influence accelerated female reproductive events.

Self-Reported Adverse Childhood Experiences and Risk for Internalizing and Externalizing Difficulties among Adolescent Custodial Grandchildren

Despite custodial grandchildren's (CG) traumatic histories and risk for psychological difficulties, knowledge is scant regarding the frequencies, types, and consequences es of adverse childhood experiences (ACEs) they have encountered. We examined self-reported ACEs via online surveys with 342 CG (ages 12 to 18) who were recruited to participate in an RCT of a social intelligence training program. ACEs were assessed by 14 widely used items, and risk for internalizing (ID) and externalizing (ED) difficulties were measured using 80th percentile cut-offs on the Strengths and Difficulties Questionnaire. Classification and regression tree analyses included all 14 ACEs (along with CG gender and age) as predictors of ID and ED risk separately. Given possible comorbidity, analyses were run with and without the other risk type as a predictor. Less than 9% of CG self-reported no ACEs, 48.6% reported two to five ACEs, and 30.5 % reported ≥ 6. Irrespective of ED risk, bullying from peers strongly predicted ID risk. ED risk was peak among CG who also had risk for ID. Without ID risk as a predictor, ED risk was highest among CG who were emotionally abused, not lived with a substance abuser, and encountered neighborhood violence. The frequency and types of ACEs observed were alarmingly higher than those among the general population, suggesting that many CG have histories of trauma and household dysfunction. That a small number of ACEs among the 14 studied here were significant predictors of ID and ED risk challenges the widespread belief of a cumulative dose ACE effect.

Long-term effects of childhood difficulties on depressive symptoms among older adults: Role of adulthood income and income satisfaction

AIM

This study examines how childhood difficulties are associated with late-life depression. Using the concept of agency within the structure of the life course perspective, this study investigates how subjective income satisfaction in adulthood plays a role in the relationship between adulthood objective income and late-life depressive symptoms among older adults who have experienced childhood difficulties.

METHODS

Using data from two waves (2006, 2021) of the Korean Welfare Panel Study (N = 1822), we identified respondents with and without childhood difficulties, and performed a series of hierarchical zero-inflated Poisson regression models.

RESULTS

Childhood difficulties (β, 0.07; 95% confidence interval [CI], 0.04-0.11), adulthood low income (β, 0.17; 95% CI, 0.13-0.21), and low income satisfaction (β, 0.16; 95% CI, 0.12-0.21) are associated with an increased level of depressive symptoms in late life. In the context of the association between objective income level and late-life depressive symptoms, the buffering effect of income satisfaction in adulthood was found among the respondents who had experienced childhood difficulties (β, 0.22; 95% CI, 0.09-0.34).

CONCLUSIONS

Childhood difficulties are a critical risk factor impacting late-life psychological well-being. How an individual subjectively evaluates his or her economic status in adulthood plays a major role in mitigating the negative impact of childhood difficulties on late-life health inequality. Interventions to reduce the risk of childhood difficulties and their negative long-lasting impact may alleviate individuals' exposure to depression in late life.

The cognitive tasks and event-related potentials associated childhood adversity: A systematic review

In this systematic review, 18 articles met inclusion criteria to be qualitatively analyzed for converging evidence of brain activity, measured using event-related potential (ERP), related to retrospectively reported childhood adversity/trauma. Using the PRISMA guidelines for systematic reviews, 917 articles were assessed for inclusion and were filtered using study parameters. The most common ERP components listed in the literature were P100, N170, N200, P200, P300, ERN, and LPP. We discuss levels of evidence for changed brain activity, each ERP component, and the tasks used to evoke them. The Childhood Trauma Questionnaire was found to be the most commonly cited measure. We note the need to assess the duration and intensity of childhood adversity/trauma measurements in the strengths and limitations of the reported childhood adversity/trauma measurements. No concrete converging evidence was found to support a relationship between ERP-measured brain activity and retrospectively reported childhood adversity/trauma. Thus, a discussion of limitations and future directions for this field of research is presented.

Associations Between Configurations of Childhood Adversity and Adult Mental Health Disorder Outcomes

The life course perspective and cumulative inequality theory suggest that childhood adversity, occurring during a sensitive period of the life course, can have long-term consequences for adult mental health and well-being. Yet, the long-term influence of adversity on adult outcomes may depend on both the features of adverse childhood experiences (e.g., the number, type, and co-occurrence of adversities) as well as the outcome assessed. Using latent class analysis applied to several waves of prospective data from the Great Smoky Mountain Study (GSMS; N=1,420) we identify subpopulations that are similar in their adversity experiences before age 18. We then predict adult internalizing and substance use disorder diagnoses by adversity experience. Results reveal five distinct classes of adversity, with unique risks for specific diagnoses in adulthood.

Exploring sex differences in trajectories of pubertal development and mental health following early adversity

Despite evidence that early life adversity (ELA) affects mental health in adolescence, we know little about sex differences in how distinct dimensions of adversity affect development and their corresponding effects on mental health. In this three-wave longitudinal study, 209 participants (118 females; ages 9-13 years at baseline) provided objective (salivary hormones, BMI, age of menarche) and subjective (perceived gonadal and adrenal status) measures of puberty and physical development, and reported on levels of internalizing and externalizing symptoms at all timepoints. Participants also reported lifetime exposure to three distinct types of ELA: deprivation, threat, and unpredictability. Using generalized additive mixed models, we tested within each sex whether dimensions of adversity were associated with longitudinal changes in measures of pubertal and physical development, and whether these indices of development were associated with trajectories of internalizing and externalizing symptoms. In females, experiences of threat and unpredictability were significantly associated with earlier pubertal timing (e.g., age of menarche) whereas experiences of deprivation were associated with steeper increases in BMI; further, faster pubertal tempo (i.e., steeper increases in pubertal stage) was associated with increases in internalizing and externalizing symptoms. In males, however, ELA was not associated with any measures of pubertal or physical development or with symptoms. Together, our results suggest that adverse experiences during early life have sex-selective consequences for pubertal and physical maturation and mental health trajectories in ways that may elucidate why females are at higher risk for mental health difficulties during puberty, particularly following exposure to unpredictable and threatening experiences of adversity.

Parental Deprivation- and Threat-Based Factors Associated with Youth Emotion-Based Neurocircuitry and Externalizing Behavior: A Systematic Review

Parental factors, including negative parenting practices (e.g., family conflict, low monitoring), parental depression, and parental substance use, are associated with externalizing behaviors among youth. However, the ways in which these parental factors are associated with youth brain function and consequent externalizing behavior has been less studied. Both the dimensional and stress acceleration models provide frameworks for understanding how parental factors may be associated with frontolimbic and frontoparietal networks implicated in emotional attention and regulation processes. The current review builds upon this work by examining how deprivation- and threat-based parental factors are associated with youth neurocircuitry involved in emotional functioning and externalizing behaviors. A systematic review using PRISMA guidelines was completed and included five studies assessing parenting behaviors, six studies assessing parental depressive symptoms and/or diagnosis, and 12 studies assessing parental history of substance use. Synthesis of reviewed studies discusses support for the dimensional and stress acceleration models within the context of deprivation and threat. Further, a limited number of studies tested (i.e., six studies) and supported (i.e., three studies) youth neural structure and function as a mediator of the association between parental factors and youth externalizing behavior. Specific recommendations for future work include more deliberate planning related to sample composition, improved clarity related to parental constructs, consistency in methodology, and longitudinal study design in order to better understand associations between contextual parental influences and youth neural and behavioral functioning.

The Association Between Adverse Childhood Experiences (ACEs), Bullying Victimization, and Internalizing and Externalizing Problems Among Early Adolescents: Examining Cumulative and Interactive Associations

Both adverse childhood experiences (ACEs) and bullying victimization are linked with mental health problems in adolescents. However, little is known about the overlap between the two factors and how this impacts adolescent mental health problems (i.e., internalizing and externalizing problems). The current study analyzed data from 8,085 participants (47.7% female; 44.1% racial/ethnic minority) in the Adolescent Brain Cognitive Development (ABCD) study, baseline (2016-2018, ages 9-10 years) to Year 2. Regression analyses were used to estimate associations between ACEs, bullying victimization and mental health problems, respectively, adjusting for sex, race/ethnicity, country of birth, household income, parental education, and study site. The findings showed that both ACEs and bullying victimization were independently associated with higher internalizing and higher externalizing problems. However, no significant interaction was found between ACEs and bullying victimization. Overall, the results align with the cumulative risk model of adversity, linking cumulative ACEs and bullying victimization to internalizing and externalizing problems in early adolescents.

Early life adversity accelerates hypothalamic drive of pubertal timing in female rats with associated enhanced acoustic startle

Early life adversity in the form of childhood maltreatment in humans or as modeled by maternal separation (MS) in rodents is often associated with an earlier emergence of puberty in females. Earlier pubertal initiation is an example of accelerated biological aging and predicts later risk for anxiety in women, especially in populations exposed to early life trauma. Here we investigated external pubertal markers as well as hypothalamic gene expression of pubertal regulators kisspeptin and gonadotropin-releasing hormone, to determine a biological substrate for MS-induced accelerated puberty. We further investigated a mechanism by which developmental stress might regulate pubertal timing. As kisspeptin and gonadotropin-releasing hormone secretion are typically inhibited by corticotropin releasing hormone at its receptor CRH-R1, we hypothesized that MS induces a downregulation of Crhr1 gene transcription in a cell-specific manner. Finally, we explored the association between pubertal timing and anxiety-like behavior in an acoustic startle paradigm, to drive future preclinical research linking accelerated puberty and anxiety. We replicated previous findings that MS leads to earlier puberty in females but not males, and found expression of kisspeptin and gonadotropin-releasing hormone mRNA to be prematurely increased in MS females. RNAscope confirmed increased expression of these genes, and further revealed that kisspeptin-expressing neurons in females were less likely to express Crhr1 after MS. Early puberty was associated with higher acoustic startle magnitude in females. Taken together, these findings indicate precocial maturation of central pubertal timing mechanisms after MS, as well as a potential role of CRH-R1 in these effects and an association with a translational measure of anxiety.

Adverse childhood experiences screening in healthcare settings: A focus on pediatric primary care

BACKGROUND

Adverse Childhood Experiences (ACEs) screening in healthcare settings is emerging as one of the tangible responses to address the consistent evidence linking ACEs with health. Kaiser Permanente Southern California (KPSC) began ACEs screening in pediatric primary care in 2018 and has developed screening and referral processes based on continued feedback from stakeholders as well as data driven assessment.

OBJECTIVE

We give an overview of the state of ACEs screening in pediatric healthcare settings, challenges facing pediatric providers, and suggestions to address them. We then describe the development of our ACEs screening and referral process within KPSC as an example of how a large healthcare system has implemented and adapted ACEs screening from pilot testing, to phased expansion, to complete implementation.

PARTICIPANTS AND SETTING

Children aged 2-18 years old who were members of KPSC 2018-2023.

RESULTS

We present data on the tailored screening and referral workflows we have developed, rates of positive screens and referrals, and how the initiation of ACEs screening may affect the rates of visit to behavioral health as a treatment option. We also integrate qualitative data to demonstrate the perspective of parents, with the goal of understanding what might help or hinder receipt of behavioral health treatment after ACEs screening.

CONCLUSIONS

We close with future directions for ACEs screening in healthcare settings and considerations for pediatric healthcare providers who may want to begin ACEs screening or adapt their screening and referral processes.

The Dichotomy of Threat and Deprivation as Subtypes of Childhood Maltreatment: Differential Functional Connectivity Patterns of Threat and Reward Circuits in an Adult Trauma Sample

BACKGROUND

Childhood maltreatment is associated with reduced activation of the nucleus accumbens, a central region in the reward network, and overactivity in the amygdala, a key region in threat processing. However, the long-lasting impact of these associations in the context of later-life stress is not well understood. The current study explored the association between childhood threat and deprivation and functional connectivity of threat and reward regions in an adult trauma sample.

METHODS

Trauma survivors (N = 169; mean age [SD] = 32.2 [10.3] years; female = 55.6%) were recruited from a level I trauma center. Two weeks after injury, participants completed the Childhood Trauma Questionnaire (measuring experiences of threat and deprivation) and underwent resting-state functional magnetic resonance imaging. Seed-to-voxel analyses evaluated the effect of childhood threat and deprivation on amygdala and nucleus accumbens resting-state connectivity.

RESULTS

Higher levels of threat were associated with increased connectivity between the right nucleus accumbens with temporal fusiform gyrus/parahippocampal gyrus and the left amygdala and the precuneus (false discovery rate-corrected p < .05). After controlling for posttraumatic symptoms 2 weeks posttrauma and lifetime trauma exposure, only the nucleus accumbens findings survived. There were no significant relationships between experiences of childhood deprivation and amygdala or nucleus accumbens connectivity.

CONCLUSIONS

Experiences of threat are associated with increased nucleus accumbens and amygdala connectivity, which may reflect a preparedness to detect salient and visual stimuli. This may also reflect a propensity toward dysregulated reward processing. Overall, these results suggest that childhood threat may be contributing to aberrant neural baseline reward and threat sensitivity later in life in an adult trauma sample.

Neuroimmune mechanisms connecting violence with internalizing symptoms: A high-dimensional multimodal mediation analysis

Violence exposure is associated with worsening anxiety and depression symptoms among adolescents. Mechanistically, social defeat stress models in mice indicate that violence increases peripherally derived macrophages in threat appraisal regions of the brain, which have been causally linked to anxious behavior. In the present study, we investigate if there is a path connecting violence exposure with internalizing symptom severity through peripheral inflammation and amygdala connectivity. Two hundred and thirty-three adolescents, ages 12-15, from the Chicago area completed clinical assessments, immune assays and neuroimaging. A high-dimensional multimodal mediation model was fit, using violence exposure as the predictor, 12 immune variables as the first set of mediators and 288 amygdala connectivity variables as the second set, and internalizing symptoms as the primary outcome measure. 56.2% of the sample had been exposed to violence in their lifetime. Amygdala-hippocampus connectivity mediated the association between violence exposure and internalizing symptoms (ζ ̂ Hipp π ̂ Hipp = 0.059 $$ {\hat{\zeta}}_{\mathrm{Hipp}}{\hat{\pi}}_{\mathrm{Hipp}}=0.059 $$ ,95 % CI boot = 0.009,0.134 $$ 95\%{\mathrm{CI}}_{\mathrm{boot}}=\left[\mathrm{0.009,0.134}\right] $$ ). There was no evidence that inflammation or inflammation and amygdala connectivity in tandem mediated the association. Considering the amygdala and the hippocampus work together to encode, consolidate, and retrieve contextual fear memories, violence exposure may be associated with greater connectivity between the amygdala and the hippocampus because it could be adaptive for the amygdala and the hippocampus to be in greater communication following violence exposure to facilitate evaluation of contextual threat cues. Therefore, chronic elevations of amygdala-hippocampal connectivity may indicate persistent vigilance that leads to internalizing symptoms.

Longitudinal associations between dimensions of maltreatment and internalizing symptoms in late adolescence: The role of inflammation during the COVID-19 pandemic

Childhood adversity and depression have been linked with heightened inflammation. However, few longitudinal studies examine how dimensions of maltreatment (i.e., abuse and neglect) differentially impact pathways to heightened inflammation and internalizing symptoms. The present study examined effects of abuse and neglect on (1) internalizing symptoms through inflammation, and (2) on inflammation through internalizing symptoms across 3 years of adolescence in the context of the COVID-19 pandemic. In a sample of 78 adolescents, significant indirect effects revealed that childhood abuse, not neglect, significantly predicted future internalizing symptoms, which predicted future heighted C-reactive protein (CRP). Using prospective longitudinal data, these findings emphasize the importance of examining distinct forms of maltreatment in understanding the developmental pathways connecting early adversity, internalizing symptoms, and inflammation.

Developmental cascade models linking contextual risks, parenting, and internalizing symptoms: A 17-year longitudinal study from early childhood to emerging adulthood

Although internalizing problems are the most common forms of psychological distress among adolescents and young adults, they have precursors in multiple risk domains established during childhood. This study examined cascading risk pathways leading to depression and anxiety symptoms in emerging adulthood by integrating broad contextual (i.e., multiple contextual risks), parental (i.e., negative parenting), and child (i.e., internalizing behaviors) characteristics in early and middle childhood. We also compared common and differential pathways to depression and anxiety symptoms depending on the conceptualization of symptom outcomes (traditional symptom dimension vs. bifactor dimensional model). Participants were 235 children (109 girls) and their families. Data were collected at 3, 6, 10, and 19 years of child age, using multiple informants and contexts. Results from a symptom dimension approach indicated mediation pathways from early childhood risk factors to depression and anxiety symptoms in emerging adulthood, suggesting common and distinct risk processes between the two disorders. Results from a bifactor modeling approach indicated several indirect pathways leading to a general internalizing latent factor, but not to symptom-specific (i.e., depression, anxiety) latent factors. Our findings highlighted comparative analytic approaches to examining transactional processes associated with later internalizing symptoms and shed light on issues of early identification and prevention.

Childhood abuse and neglect and profiles of adult emotion dynamics

Childhood maltreatment (CM) is experienced by ∼40% of all children at major personal and societal costs. The divergent associations between emotional, physical, and sexual abuse or neglect in childhood and differences in adult emotional functioning and regulation were examined in terms of daily emotion intensity, variability, instability, inertia, and diversity, reported over 30 days by 290 Dutch aged 19-73. Participants described their abuse/neglect experiences retrospectively using the Childhood Trauma Questionnaire (CTQ). Dissecting CM effects on adult emotion dynamics may inform theories on the ontogenesis and functioning of emotions, on effects of abuse and neglect, to better understand (dys)functional emotional development, and to prevent their adverse sequelae. Structural equation models (SEM) showed that most types of CM were associated with specific patterns of emotion dynamics, and only emotional abuse had no unique effects on the emotional dynamic indices. Emotional neglect was associated with most measures of emotion dynamics (i.e., less intense, variable, unstable, and diverse emotions). Sexual abuse associated with increases and physical neglect decreases in negative affect variability and instability. Physical abuse was associated with inertia but with a small effect size. Social contact frequency did not mediate much of the relationship between CM types and emotion dynamics.

The Development of Stress Reactivity and Regulation in Children and Adolescents

Adversity experienced in early life can have detrimental effects on physical and mental health. One pathway in which these effects occur is through the hypothalamic-pituitary-adrenal (HPA) axis, a key physiological stress-mediating system. In this review, we discuss the theoretical perspectives that guide stress reactivity and regulation research, the anatomy and physiology of the axis, developmental changes in the axis and its regulation, brain systems regulating stress, the role of genetic and epigenetics variation in axis development, sensitive periods in stress system calibration, the social regulation of stress (i.e., social buffering), and emerging research areas in the study of stress physiology and development. Understanding the development of stress reactivity and regulation is crucial for uncovering how early adverse experiences influence mental and physical health.

Anhedonia mediates the relationships between childhood trauma and symptom severity of PTSD and depression, but not of social anxiety

BACKGROUND

Childhood trauma is a risk factor for developing multiple forms of psychopathology, including depression, posttraumatic stress disorder (PTSD), and social anxiety. Yet, the mechanisms linking childhood trauma and these psychopathologies remain less clear.

OBJECTIVE

Here we examined whether anhedonia, a reduced ability to experience pleasure, may mediate the relationship between childhood trauma and symptom severity of depression, PTSD, and social anxiety.

METHODS

A total of 230 trauma-exposed participants aged 18-75 were assessed for lifetime trauma exposure, including general and childhood traumatic events, anhedonia, and symptoms of depression, PTSD, and social anxiety.

RESULTS

Controlling for age, gender, and general lifetime trauma exposure, mediation analyses revealed a significant mediation effect of anhedonia for the relationship between childhood trauma and symptom severity of depression and PTSD, but not social anxiety. To better understand these significant mediation effects, we repeated the analyses separately for childhood abuse and neglect, and then for the various subtypes of each type of childhood trauma. Results showed a significant mediation effect of anhedonia on symptoms of both depression and PTSD in individuals who reported high emotional and sexual abuse levels. F Anhedonia was also found to mediate the relationship between both emotional and physical neglect and symptoms of depression and PTSD.

CONCLUSION

These findings refine our understanding of the ways in which childhood traumatic experiences may be associated with different mental health problems by increasing anhedonia. Anhedonia may be an important treatment target in survivors of childhood abuse and neglect.

Does biological age mediate the relationship between childhood adversity and depression? Insights from the Detroit Neighborhood Health Study

The link between childhood adversity and adulthood depression is well-established; however, the underlying mechanisms are still being explored. Recent research suggests biological age may mediate the relationship between childhood adversity and depression in later life. This study examines if biological age mediates the relationship between childhood adversity and depression symptoms using an expanded set of biological age measures in an urban population-based cohort. Data from waves 1-3 of the Detroit Neighborhood Health Study (DNHS) were used in this analysis. Questions about abuse during childhood were coded to form a childhood adversity score similar to the Adverse Childhood Experience measure. Multiple dimensions of biological age, defined as latent variables, were considered, including systemic biological age (GrimAge, PhenoAge), epigenetic age (Horvath, SkinBlood), and immune age (cytomegalovirus, herpes simplex virus type 1, C-reactive protein, interleukin-6). Depression symptoms, modeled as a latent variable, were captured through the Patient Health Questionnaire-9 (PHQ-9). Models were adjusted for age, gender, race, parent education, and past depressive symptoms. Total and direct effects of childhood adversity on depression symptoms and indirect effects mediated by biological age were estimated. For total and direct effects, we observed a dose-dependent relationship between cumulative childhood adversity and depression symptoms, with emotional abuse being particularly influential. However, contrary to prior studies, in this sample, we found few direct effects of childhood adversity on biological age or biological age on depression symptoms and no evidence of mediation through the measures of biological age considered in this study. Further research is needed to understand how childhood maltreatment experiences are embodied to influence health and wellness.

[Emotional Abuse in Childhood and Adolescence: Biological Embedding and Clinical Implications]

Emotional abuse, defined as degrading, manipulative, or neglectful behaviors by caregivers, represents a common adverse experience for children and adolescents, often co-occurring with other maltreatment types. Exposure to emotional abuse significantly affects mental health across the lifespan and is particularly associated with elevated depression risk.This review examinesmechanisms, by which emotional abuse influences brain development and the neuroendocrine stress response system and discusses the roles of genetic vulnerability and epigenetic processes in contributing to an elevated mental health risk. Emotional abuse has similar effects on brain networks responsible for emotion processing and regulation as other maltreatment types.Moreover, it uniquely affects networks related to self-relevant information and socio-cognitive processes. Furthermore, emotional abuse is associated with an impaired recovery of the neuroendocrine response to acute stress. Similar to other maltreatment types, emotional abuse is associated with epigenetic changes in genes regulating the neuroendocrine stress response system that are implicated in increased mental health risk.These findings suggest that emotional abuse has equally detrimental effects on children'smental health as physical or sexual abuse, warranting broader societal awareness and enhanced early detection efforts. Early interventions should prioritize emotion regulation, social cognition, self-esteemenhancement, and relationship- oriented approaches for victims of emotional abuse.

Behavioral and psychiatric correlates of brain responses to social feedback

Maladaptive responses to peer acceptance and rejection arise in numerous psychiatric disorders in adolescence; yet, homogeneity and heterogeneity across disorders suggest common and unique mechanisms of impaired social function. We tested the hypothesis that social feedback is processed similarly to other forms of feedback (e.g., monetary) by examining the correspondence between the brain's response to social acceptance and rejection and behavioral performance on a separate reward and loss task. We also examined the relationship between these brain responses and depression and social anxiety severity. The sample consisted of one hundred and thirteen 16-21-year olds who received virtual peer acceptance/rejection feedback in an event-related potential (ERP) task. We used temporospatial principal component analysis and identified a component consistent with the reward positivity (RewP) or feedback negativity (FN). RewP to social acceptance was not significantly related to reward bias or the FN to social rejection related to loss avoidance. The relationship between RewP and depression severity, while nonsignificant, was of a similar magnitude to prior studies. Exploratory analyses yielded a significant relationship between lower socioeconomic status (SES) and blunted RewP and between lower SES and heightened loss avoidance and blunted reward bias. These findings build on prior work to improve our understanding of the function of the brain's response to social feedback, while also suggesting a pathway for further study, whereby poverty leads to depression via social and reward learning mechanisms.

Caregiver adverse childhood experiences and preschool externalizing problems: The role of factors that contribute to caregiver resilience

BACKGROUND

Preschool children with externalizing problems are at risk for short- and long-term difficulties and preschool externalizing problems (PEP) are influenced by several caregiver factors. One such factor is caregiver adverse childhood experiences (ACEs). Researchers have investigated how caregiver ACEs are related to PEP by identifying risk factors to account for this association. However, research on caregiver factors associated with fewer PEP is limited. Particularly, factors that contribute to caregiver resilience may be adaptive caregiver characteristics that negatively relate to PEP, even when adjusting for caregiver ACEs.

OBJECTIVE

The present study sought to address a gap in the literature by examining the impact of different types of factors that contribute to caregiver resilience (e.g., caregiver social-ecological factors or caregiver positive childhood experiences) as promotive factors of lower PEP.

PARTICIPANTS AND SETTING

Participants included 125 caregiver-child dyads recruited from the community.

METHOD

Participating caregivers completed measures of their own and their child's demographic information, caregiver ACEs, caregiver social-ecological factors, caregiver positive childhood experiences, and PEP.

RESULTS

Overall, positive caregiver childhood experiences (r = -0.25, p < .01), and not caregiver social-ecological factors (r = -0.13, p = .15), demonstrated a significant negative association with PEP. However, this relation became statistically non-significant when adjusting for caregiver ACEs (β = -0.12, p = .20).

CONCLUSIONS

Given the association between caregiver ACEs and PEP, this study highlights the importance of assessing a caregiver's ACEs, specifically when working with caregivers seeking parent training for disruptive child behaviors. There should be a continued focus on ecological and family strengths and differential impacts as they relate to PEP.

Hyperactivity and Impulsivity Symptoms Mediate the Association Between Adverse Childhood Experiences and Reading Achievement: A LONGSCAN Cohort Study

Adverse Childhood Experiences (ACEs) include various childhood stressors that can negatively impact the health and well-being of children. ACEs are associated with poor academic achievement. Attention is strongly associated with academic achievement, and there is a graded relationship between ACEs exposure and subsequent development of parent-reported ADHD; however, it is unclear whether ADHD symptoms mediate the relationship between ACEs and academic achievement. This study tested a model of mediation by ADHD symptoms between ACEs and academic achievement (measured by reading score). This retrospective cohort analysis utilized data from the Longitudinal Study on Child Abuse and Neglect (LONGSCAN), a data consortium exploring the impact of child maltreatment (n = 494). There were relatively even numbers of male and female child participants, and the majority of caregivers were either non-Hispanic White or Black. Path analyses were modeled for ACEs as a sum score and separately for individual ACE exposures, with number of symptoms of Inattention (IN) and Hyperactivity/Impulsivity (H/I) as mediators, and academic achievement as the outcome, adjusting for covariates. ACEs were highly prevalent in this sample (M = 5.10, SD = 1.90). After retaining significant covariates, significant direct associations (P < .05) were seen between ACE sum score and IN (β = .14) and H/I (β = .21), and between H/I and reading score (β=-.14). A higher ACE score was associated with lower reading scores through variation in H/I, but not IN. H/I mediated the relationship between ACEs and reading score in this high-risk population, providing new insight into relationships between ACEs and academic achievement, which can inform interventions.

Protective factors for resilience in adolescence: analysis of a longitudinal dataset using the residuals approach

INTRODUCTION

The residuals approach, in which residual scores from regression models are used as a proxy for resilient functioning, offers great potential to increase understanding of resilience processes. However, its application in child and adolescent wellbeing research is limited to date. We use this approach to examine how adversity exposure impacts later wellbeing (life satisfaction, and internalising mental health difficulties) in the early-to-middle adolescence transition; whether gender and ethnic differences in resilience exist; which internal and external factors confer protective effects for resilience; and, whether the protective effect of these factors differs by gender and level of adversity exposure.

METHOD

Secondary analysis of the #BeeWell longitudinal data set (N = 12,130 adolescents, aged 12/13 at T1 and 13/14 at T2, representative of Greater Manchester, England) was undertaken, using a series of linear regressions to establish adversity indices for later wellbeing, before assessing the protective effects of internal and external factors on resilience.

RESULTS

Multiple adversity factors (e.g., home material deprivation, sexuality discrimination, bullying) were found to impact later wellbeing. Girls and white adolescents presented lower levels of resilience than their peers. Internal psychological factors (self-esteem, emotional regulation, optimism) consistently conferred the strongest protective effects, but behavioural/activity factors (physical activity, sleep) also contributed to resilience. Among external factors, friendships and peer support were the most salient. Physical activity yielded stronger protective effects among boys (compared to girls). Effects of protective factors were stronger among those at lower (compared to higher) levels of adversity exposure.

CONCLUSION

The residuals approach can make a considerable contribution to our understanding of the interplay between adversity exposure and access to protective factors in determining adolescent wellbeing outcomes. Moreover, its application provides clear implications for policy and practice in terms of prevention (of adversity exposure) and intervention (to facilitate resilience).

Adopting a child perspective for exposome research on mental health and cognitive development - Conceptualisation and opportunities

Mental disorders among children and adolescents pose a significant global challenge. The exposome framework covering the totality of internal, social and physical exposures over a lifetime provides opportunities to better understand the causes of and processes related to mental health, and cognitive functioning. The paper presents a conceptual framework on exposome, mental health, and cognitive development in children and adolescents, with potential mediating pathways, providing a possibility for interventions along the life course. The paper underscores the significance of adopting a child perspective to the exposome, acknowledging children's specific vulnerability, including differential exposures, susceptibility of effects and capacity to respond; their susceptibility during development and growth, highlighting neurodevelopmental processes from conception to young adulthood that are highly sensitive to external exposures. Further, critical periods when exposures may have significant effects on a child's development and future health are addressed. The paper stresses that children's behaviour, physiology, activity pattern and place for activities make them differently vulnerable to environmental pollutants, and calls for child-specific assessment methods, currently lacking within today's health frameworks. The importance of understanding the interplay between structure and agency is emphasized, where agency is guided by social structures and practices and vice-versa. An intersectional approach that acknowledges the interplay of social and physical exposures as well as a global and rural perspective on exposome is further pointed out. To advance the exposome field, interdisciplinary efforts that involve multiple scientific disciplines are crucial. By adopting a child perspective and incorporating an exposome approach, we can gain a comprehensive understanding of how exposures impact children's mental health and cognitive development leading to better outcomes.

Patterns of Childhood Adversity among Women with and without Childhood ADHD: Links to Adult Psychopathology and Global Functioning

We examine the outcomes associated with childhood adversity for women with and without carefully diagnosed childhood ADHD, via an ethnically diverse sample of 140 participants with ADHD (Mage = 9.7) and 88 age- and ethnicity-matched comparisons (Mage = 9.4). At adult follow-up, we retained 211 of the original 228 participants (92.6%; Mage = 25.6). We used latent class analysis to identify patterns of childhood adversity and examine their association with adult global functioning and psychopathology. Key findings: (1) Four childhood adversity classes emerged (Low Exposure, Familial Dysfunction, Emotional Maltreatment, Pervasive Exposure); (2) Childhood ADHD predicted membership in the Emotional Maltreatment class; and (3) Childhood adversity classes were differently associated with adult outcomes, such that membership in both the Emotional Maltreatment and Pervasive Exposure classes predicted significantly higher internalizing and externalizing symptoms as well as significantly lower global functioning than women in the Low Exposure class. Furthermore, compared to the Emotional Maltreatment class, the Familial Dysfunction class had lower externalizing symptoms, whereas the Pervasive Exposure class had lower global functioning and higher internalizing symptoms by adulthood. Findings provide information about girls and women who could be targeted for intervention in terms of ADHD behavior patterns plus adverse experiences in childhood. Beyond limitations, we discuss the need to investigate the confluence of neurodevelopmental conditions and adverse child events with respect to maladaptive outcomes.

Patterns of Trauma Among Youth Seeking Mental Health Services at a Community-Based Clinic: A Latent Class Analysis Approach

We examine the association between trauma patterns, gender identity, ethnicity, foster care involvement, and mental health needs in a sample of low-income youth. Our community sample included 2,175 clients aged 6 or older (Mage = 11.9), has a closely-even gender ratio (55% female and 45% male and others) and is ethnically diverse (37% Black, 31% Multiracial, 14% Latinx, 9% White, 10% Others). 61% of youth in this sample have involvement with the foster care system. Latent class analysis was used to identify trauma patterns, explore predictors of latent class membership, and estimate the cumulative mental health needs for each trauma class. Results revealed four trauma patterns (Low Trauma, Caregiving Disruption, Community Violence, and Multiple Trauma). Girls were more likely than boys to be in the high-trauma groups. Compared to Black youth, Latinx youth were more likely to be in the Multiple Trauma class, whereas White youth were less likely to be in the high trauma classes. Youth with past or current involvement with the foster care system were more likely than those without to be in the high-trauma classes. Mental health needs for youth in Low Trauma and Caregiving Disruption were comparable, but were highest for those in Community Violence. Contrary to expectation, the Multiple Trauma group did not have the highest-level mental health needs. Interventions for low-income youth can benefit from knowing which trauma patterns are associated with various levels of mental health needs. Newer models of care focusing on building healthy communities may be the way forward.

On Navigating Analytical Choices in Research on Early Life Adversity: A Commentary on Sisitsky et al. (2023)

Early life adversities (ELA), including exposure to childhood maltreatment, deprivation or community violence, rarely occur in isolation. This co-occurrence poses several conceptual and methodological challenges for researchers, who must decide how best to model ELA and its association with outcomes. In this commentary, we discuss how different analytical choices come with their own - often complementary - sets of assumptions, strengths and limitations, which should be carefully considered when designing research on ELA. We then summarize work published in this issue by Sisitsky et al. (Research on Child and Adolescent Psychopathology, 2023), which serves as an important example of how different approaches can be incorporated in research in order to capture ELA as a complex phenomenon, while generating actionable results. Ultimately, such integration can enhance the quality and relevance of research, contributing to a more comprehensive understanding of ELA and its effects on health outcomes, paving the way for more targeted prevention and intervention strategies to promote children's wellbeing.

What's Next? Advances and Challenges in Understanding How Environmental Predictability Shapes the Development of Cognitive Control

Forming predictions about what will happen next in the world happens early in development, without instruction, and across species. Some environments support more accurate predictions. These more predictable environments also support what appear to be positive developmental trajectories, including increases in cognitive control over thoughts and actions. Such consequences of predictable environments have broad-reaching implications for society and have been explained across ecological, psychological, computational, and neural frameworks. However, many challenges remain in understanding the effects of environmental predictability, including adaptive responses to unpredictable environments and the mechanisms underlying the effects of predictable environments on developmental trajectories. Future work addressing different dimensions of predictability -- across time scales, locations, actions, people, and outcomes -- and their interactions will advance the ability to understand, predict, and support developmental trajectories.

Networks of Adversity in Childhood and Adolescence and Their Relationship to Adult Mental Health

Adverse experiences before the age of eighteen are common and include diverse events ranging from sexual abuse to parental divorce. These stressful experiences have been linked to physical and mental health issues. Previous research has focused mainly on childhood adversity, such as experiences in the family environment. Little consideration has been given to adversities that may be particularly harmful in adolescence. To understand adolescents' adverse experiences, this project used data from the Avon Longitudinal Study of Parents and Children (ALSPAC, total N = 14,901, N ≈ 1,200 - 10,000 per measure). We modelled interrelations of adversities in childhood (1-11 years) and adolescence (11-23 years) and examined adversity clusters using network analysis. We found two similar clusters in the childhood and adolescence networks: (1) direct abuse and (2) adverse family factors. We identified a third cluster of (3) educational and social adversities for adolescence. For both age groups, emotional abuse in the family environment was closely linked to mental health in early adulthood and most adversities were linked with depression in early adulthood. In adolescence, housing and academic issues and abuse by a romantic partner were particularly central to the network of adversities. Thus, we found commonalities and differences in the relevance of adverse experiences at different developmental stages. These findings highlight the need to develop age-dependent frameworks for adversity research and policymaking.

Differential Associations of Adversity Profiles with Adolescent Cognitive Control and Psychopathology

Adverse childhood experiences are common and have long-term consequences for biological and psychosocial adjustment. We used a person-centered approach to characterize distinct profiles of adversity in early adolescence and examined associations with later cognitive control and psychopathology. The sample included 167 adolescents (47% female) and their primary caregivers who participated in a longitudinal study across four time points (approximately one year between assessments). At Time 1 (Mage = 14 years), we measured seven indicators of adversity: socioeconomic disadvantage, abuse, neglect, household chaos, parent substance use, parent depression, and negative life events. At Times 2-4, adolescents' behavioral performance and functional activation during a cognitive control task were measured. At Time 5, adolescents and their caregiver reported on adolescent internalizing and externalizing symptomatology. Using latent profile analysis, we identified four distinct adversity subgroups: a low exposure group, a neglect group, a household instability group, and a poly-adversity group. These groups significantly differed on subsequent levels of psychopathology, but not cognitive control. Specifically, the poly-adversity group reported significantly higher levels of both internalizing and externalizing symptomatology relative to the low exposure group, and the household instability group demonstrated elevated risk for externalizing symptomatology. When using a cumulative risk approach, higher levels of adversity exposure were associated with significantly worse cognitive control performance (but not neural activation). These results suggest that psychopathology outcomes may be differentially predicted by distinct patterns of risk, and that cognitive control impairment may be more strongly predicted by cumulative risk.

Does reward processing moderate or mediate the link between childhood adversity and psychopathology: A longitudinal study

Childhood adversity is common and associated with elevated risk for transdiagnostic psychopathology. Reward processing has been implicated in the link between adversity and psychopathology, but whether it serves as a mediator or moderator is unclear. This study examined whether alterations in behavioral and neural reward processing function as a mechanism or moderator of psychopathology outcomes following adversity experiences, including threat (i.e., trauma) and deprivation. A longitudinal community sample of 10-15-year-old youths was assessed across two waves (Wave 1: n = 228; Wave 2: n = 206). Wave 1 assessed adverse experiences, psychopathology symptoms, reward processing on a monetary incentive delay task, and resting-state fMRI. At Wave 2, psychopathology symptoms were reassessed. Greater threat experiences were associated with blunted behavioral reward sensitivity, which, in turn, predicted increases in depression symptoms over time and mediated the prospective association between threat and depression symptoms. In contrast, reward sensitivity moderated the association between deprivation experiences and prospective externalizing symptoms such that the positive association of deprivation with increasing externalizing symptoms was absent for children with high levels of reward sensitivity.

Reciprocal associations between early maladaptive schemas and depression in adolescence: long-term effects of childhood abuse and neglect

BACKGROUND

Adolescent depression has grown to be a major social concern in China. During the coronavirus pandemic, the incidence of depression among Chinese adolescents increased substantially. More research is required to inform the prevention and intervention of adolescent depression in China. Depression is associated with Early Maladaptive Schemas (EMSs). Childhood abuse and neglect are distal antecedents of adolescent depression. It is not known how depression and EMSs interact in adolescence and how childhood abuse and neglect contribute to this relationship. This study aimed to examine the reciprocal relationships between depression and EMSs, as well as the long-term effects of childhood abuse and neglect on depression and EMSs during adolescence. The work also investigates gender differences in these mechanisms.

METHODS

Using a two-wave longitudinal design, we recruited 3,485 Chinese adolescents (Mage = 13.2; 43.2% females) from three Shanxi Province, China middle schools. All participants completed self-report questionnaires addressing childhood abuse and neglect, depression, and EMSs. Structural equation models examined reciprocal relationships between depression and EMS, as well as the effect of childhood abuse and neglect on depression and EMSs. Multi-group analysis addressed gender differences.

RESULTS

Results indicated that greater depression predicted more EMSs measured later, but EMSs did not predict subsequent depression. Childhood abuse and neglect had different effects on depression and EMSs during adolescence. Specifically, exposure to childhood abuse related to more severe depression and EMSs in adolescence and contributed to the perpetuation of EMSs by increasing depression. Exposure to childhood neglect showed a direct effect on depression and indirectly reinforced subsequent EMSs through depression. There were no gender differences.

CONCLUSION

These findings contribute to a better understanding of the emergence and course of depression in early adolescence, suggesting that childhood abuse and neglect are critical early risk factors. Additionally, depression plays a key role in promoting schema perpetuation among adolescents exposed to childhood maltreatment, providing important implications for relevant prevention and intervention in early adolescence.

Parental mental health trajectories over the COVID-19 pandemic and links with childhood adversity and pandemic stress

BACKGROUND

The COVID-19 pandemic has created significant disruptions, with parents of school-age children being identified as a vulnerable population. Limited research has longitudinally tracked the mental health trajectories of parents over the active pandemic period. In addition, parents' history of adverse (ACEs) and benevolent (BCEs) childhood experiences may compound or attenuate the effect of COVID-19 stressors on parental psychopathology.

OBJECTIVE

To identify distinct longitudinal trajectories of parental mental health over the COVID-19 pandemic and how these trajectories are associated with parental ACEs, BCEs, and COVID-19 stress.

PARTICIPANTS AND SETTING

547 parents of 5-18-year-old children from the U.K., U.S., Canada, and Australia.

METHODS

Growth mixture modelling was used to identify trajectories of parental mental health (distress, anxiety, post-traumatic stress, and substance use) from May 2020 to October 2021. COVID-19 stress, ACEs, and BCEs were assessed as predictors of mental health trajectories via multinomial logistic regression.

RESULTS

Two-class trajectories of "Low Stable" and "Moderate Stable" symptoms were identified for psychological distress and anxiety. Three-class trajectories of "Low Stable", "High Stable", and "High Decreasing" symptoms were observed for post-traumatic stress. Reliable trajectories for substance use could not be identified. Multinomial logistic regression showed that COVID-19 stress and ACEs independently predicted membership in trajectories of greater mental health impairment, while BCEs independently predicted membership in trajectories of lower psychological distress.

CONCLUSIONS

Parents experienced mostly stable mental health symptomatology, with trajectories varying by overall symptom severity. COVID-19 stress, ACEs, and BCEs each appear to play a role in parents' mental health during this unique historical period.
