The importance of interactions between child temperament and parenting has been accepted ever since Thomas and Chess (1977) proposed their “goodness-of-fit” construct, but over the last three decades, pertinent research has grown exponentially. Researchers examining child characteristics that can moderate the effects of socialization have tested increasingly complex, nuanced, and sophisticated models, largely inspired by the highly influential frameworks of child plasticity or differential susceptibility (Belsky & Pluess, 2009). Yet, multiple questions remain unsettled. We addressed four such questions as applied to predicting children’s observed disregard for rules at age 4.5 in a study of 200 community families from the US Midwest. (a) We examined children’s observed negative emotionality at 16 months, most commonly seen as a plasticity “trait,” but separating anger and fear proneness, which may differently moderate effects of socialization. (b) We examined two separate aspects of observed parental socialization at age 3, mutually responsive orientation and power assertion. (c) We distinguished analytically diathesis-stress from differential susceptibility. (d) We examined all effects in mother– and father–child relationships. We supported both diathesis-stress and differential susceptibility, depending on the facet of negative emotionality, the aspect of socialization considered, and parental gender, highlighting the nuanced nature of the processes involved.

Limited data exists on the role of attachment in influencing the development and wellbeing of refugee children. Herein we describe patterning and correlates of attachment in an Australian sample of adolescent Tamil refugees. Sixty-eight adolescents, aged 10–18, were assessed for trauma exposure, mental health problems and pattern of attachment. Attachment representations were assessed by discourse analysis of structured attachment interviews. Mothers of the adolescents were assessed for post-migration family stressors, depression, and post-traumatic stress disorder (PTSD) using self-report measures. Inhbitory A and A+ patterns of attachment predominated. Attachment insecurity was associated with child trauma exposure (β = .417), post-migration family stressors (β = .297) and maternal PTSD (β = .409). Path modeling demonstrated that attachment insecurity mediated associations of child trauma exposure, family stressors and maternal PTSD with child mental health problems, the model yielding adequate fit (Comparative Fit Index [CFI] = .957; standardized root mean square residual [SRMR] = .066; R2 .449). Our cross-sectional findings suggest that compromised attachment security is one potential mechanism by which the adverse effects of refugee family trauma and adversity are transmitted to children. Resettlement policy and psychosocial services should aim to preserve and/or reestablish attachment security in child-caregiver relationships through policy that reduces family stressors and interventions that bolster parental mental health and caregiver sensitivity.

This study explores patterns of self-regulation and emotional well-being among Syrian refugee children in Lebanon, employing a person-centered approach, responding to theoretical challenges articulated by Dante Cicchetti and other psychologists. Using latent profile analysis with data from 2,132 children, we identified seven distinct profiles across cognitive regulation, emotional-behavioral regulation, interpersonal regulation, and emotional well-being. These profiles showed significant heterogeneity in patterns of self-regulation across domains and emotional well-being among Syrian children. Some profiles consistently exhibited either positive (“Well-regulated and Adjusted”) or negative (“Moody and Frustrated”) functioning across all domains, while others revealed domain-specific challenges, e.g., particularly sensitive to interpersonal conflict. This heterogeneity in the organization of self-regulatory skill and emotional well-being challenges the traditional homogeneous view of child development in conflict settings. The study also underscores the profiles’ differential associations with demographic characteristics and experiences, with school-related experiences being particularly salient. We discuss the implications of these findings for future research in developmental psychopathology on self-regulation and emotional well-being in conflict-affected contexts. In addition, we advocate for tailored interventions to meet the diverse needs of children affected by conflict.

School connectedness may offset mental health risks associated with childhood adversity. The present study examined the potential protective effects of school connectedness against childhood adversity when predicting adolescent mental health outcomes in 9,964 individuals (51% female, 81% white) from the Millennium Cohort Study. Structural equation models were fitted to examine the longitudinal relationships between childhood adversity, school connectedness, and adolescent mental health. Childhood adversity was a risk factor, predicting greater internalizing and externalizing problems and lower levels of positive mental health. School connectedness was a promotive factor as it predicted fewer mental health problems and greater positive mental health. Furthermore, school connectedness at age 11 was protective against childhood adversity when predicting internalizing and externalizing problems at age 14. That is, students with a history of adversity who felt more connected to school were less likely to exhibit internalizing and externalizing symptoms than those who felt less connected to school. Only school connectedness at age 11 was protective against childhood adversity, indicating that feeling connected to school at younger ages may disrupt processes linking childhood adversity to adolescent mental health. Schools should foster students’ feelings of connectedness to protect vulnerable individuals and benefit all pupils’ mental health.

Cognitive abilities are heritable and influenced by socioeconomic status (SES). It is critical to understand the association between SES and cognition beyond genetic propensity to inform potential benefits of SES-based interventions and to determine if such associations vary across (i) cognitive domains, (ii) facets of SES, and/or (iii) genetic propensity for different aspects of cognition. We examined the contributions of neighborhood socioeconomic advantage, family income, and polygenic scores (PGS) for domains of cognition (i.e., general cognitive ability, executive function, learning and memory, fluid reasoning) in a sample of children (ages 9–10; n = 5549) most genetically similar to reference populations from Europe. With some variability across cognitive outcomes, family income and PGS were independently significantly associated with cognitive performance. Within-sibling analyses revealed that cognitive PGS associations were predominantly driven by between-family effects suggestive of non-direct genetic mechanisms. These findings provide evidence that SES and genetic propensity to cognition have unique associations with cognitive performance in middle childhood. These results underscore the importance of environmental factors and genetic influences in the development of cognitive abilities and caution against overinterpreting associations with PGS of cognitive and educational outcomes as predominantly direct genetic effects.

Suicide rates are rising among U.S. youth, yet our understanding of developmental mechanisms associated with increased suicide risk is limited. One high-risk pathway involves an interaction between heritable trait impulsivity and emotion dysregulation (ED). Together, these confer increased vulnerability to nonsuicidal self-injury (NSSI), suicide ideation (SI), and suicide attempts (SAs). Previous work, however, has been limited to homogeneous samples. We extend the Impulsivity × ED hypothesis to a more diverse sample of adolescents (N = 344, ages 12–15 at Baseline, 107 males and 237 females) who were treated for major depression and assessed four times over two years. In multilevel models, the impulsivity × ED interaction was associated with higher levels and worse trajectories of NSSI, SI, and SAs. As expected, stressful life events were also associated with poorer trajectories for all outcomes, and NSSI was associated with future and concurrent SI and SAs. These findings extend one developmental pathway of risk for self-harming and suicidal behaviors to more diverse adolescents, with potential implications for prevention.

Autism spectrum disorder prevalence more than quadrupled in the United States between 2000 and 2020. Ice storm-related prenatal maternal stress (PNMS) predicts autistic-like trait severity in children exposed early in gestation. The objective was to determine the extent to which PNMS influences the severity and trajectory of autistic-like traits in prenatally flood-exposed children at ages 4–7 years and to test moderation by sex and gestational timing. Soon after the June 2008 floods in Iowa, USA, 268 women pregnant during the disaster were assessed for objective hardship, subjective distress, and cognitive appraisal of the experience. When their children were 4, 5½, and 7 years old, mothers completed the Social Communication Questionnaire (SCQ) to assess their children’s autistic-like traits; 137 mothers completed the SCQ for at least one age. The final longitudinal multilevel model showed that the greater the maternal subjective distress, the more severe the child’s autistic-like traits, controlling for objective hardship. The effect of PNMS on rate of change was not significant, and there were no significant main effects or interactions involving sex or timing. Prenatal maternal subjective distress, but not objective hardship or cognitive appraisal, predicted more severe autistic-like traits at age 4, and this effect remained stable through age 7.

Similar to adults with posttraumatic stress disorder, children with early life adversity show bias in memory for negative emotional stimuli. However, it is not well understood how childhood adversity impacts mechanisms underlying emotional memory. N = 56 children (8–14 years, 48% female) reported on adverse experiences including potentially traumatic events and underwent fMRI while attending to emotionally pleasant, neutral, or negative images. Post-scan, participants completed a cued recall test to assess memory for these images. Emotional difference-in-memory (DM) scores were computed by subtracting negative or positive from neutral recall performance. All children showed enhancing effects of emotion on recall, with no effect of trauma load. However, children with less trauma showed a larger emotional DM for both positive and negative stimuli when amygdala or anterior hippocampal activity was higher. In contrast, highly trauma-exposed children demonstrated a lower emotional DM with greater amygdala or hippocampal activity. This suggested that alternative neural mechanisms might support emotional enhancement of encoding in children with greater trauma load. Whole-brain analyses revealed that right fusiform activity during encoding positively correlated with both trauma load and successful later recall of positive images. Therefore, highly trauma-exposed children may use alternative, potentially adaptive neural pathways via the ventral visual stream to encode positive emotional events.

Childhood maltreatment is linked with later depressive symptoms, but not every maltreated child will experience symptoms later in life. Therefore, we investigate whether genetic predisposition for depression (i.e., polygenic score for depression, PGSDEP) modifies the association between maltreatment and depressive symptoms, while accounting for different types of maltreatment and whether it was evaluated through prospective and retrospective reports. The sample included 541–617 participants from the Quebec Longitudinal Study of Child Development with information on maltreatment, including threat, deprivation, assessed prospectively (5 months–17 years) and retrospectively (reported at 23 years), PGSDEP and self-reported depressive symptoms (20–23 years). Using hierarchical linear regressions, we found that retrospective, but not prospective indicators of maltreatment (threat/deprivation/cumulative) were associated with later depressive symptoms, above and beyond the PGSDEP. Our findings also show the presence of gene–environment interactions, whereby the association between maltreatment (retrospective cumulative maltreatment/threat, prospective deprivation) and depression was strengthened among youth with higher PGSDEP scores. Consistent with the Diathesis-Stress hypothesis, our findings suggest that a genetic predisposition for depression may exacerbate the putative impact of maltreatment on later depressive symptoms, especially when maltreatment is retrospective. Understanding the gene–environment interplay emerging in the context of maltreatment has the potential to guide prevention efforts.

Child maltreatment impacts approximately one in seven children in the United States, leading to adverse outcomes throughout life. Adolescence is a time period critical for the development of executive function, but there is little research examining how abuse and neglect may differently affect the developmental trajectories of executive function throughout adolescence and into young adulthood. In the current study, 167 adolescents participated at six time points from ages 14 to 20. At each time point, adolescents completed behavioral tasks measuring the three dimensions of executive function (working memory, inhibitory control, and cognitive flexibility). Neglect and abuse in early life (ages 1–13) were reported at ages 18–19. Unconditional growth curve models revealed age-related improvement in all three executive function dimensions. Conditional growth curve models tested the prospective effects of recalled neglect and abuse on the developmental trajectories of executive function. The results revealed that neglect was associated with developmental changes in working memory abilities, such that greater levels of neglect during ages 1–13 were associated with slower increases in working memory abilities across ages 14–20. These findings highlight the adverse consequences of early neglect experiences shown by delayed working memory development during adolescence into young adulthood.

Parenting behaviors play an important role in the transmission of depressive symptoms from mothers to children. Although reduced positive affect is a central feature of depression, models of intergenerational transmission have neglected maternal socialization of positive affect as a mediating mechanism. This study investigated whether maternal responses to infant positive affect mediate the link between mothers’ and toddlers’ depressive symptoms. A community sample of 128 mothers (58% White) and their infants (Mage = 6.65 months, SD = 0.53 at first visit) participated in 3 assessments over a 1-year period. Assessments included self-reports of postpartum depressive symptoms, observational measures of maternal responses to infant positive affect and maternal sensitivity, and mother report of toddlers’ depressive problems. Mediation analyses revealed that mothers with elevated postpartum depressive symptoms displayed fewer supportive responses to their infants’ positive affect. In turn, infants who received fewer supportive responses had more depressive problems in toddlerhood. The indirect effect of postpartum depressive symptoms on toddlers’ depressive problems via maternal supportive responses remained significant after controlling for maternal sensitivity. Findings suggest that maternal responses to infant positive affect play a unique role in the intergenerational transmission of depressive symptoms. The theoretical and practical implications of these findings are discussed.

We investigated cross-sectional and longitudinal associations between neonate microbial exposure and emerging behavioral temperament measures at the ages of 1, 2, and 3 years. Infants and mothers (n = 335) were extracted from the Kuopio Birth Cohort Study. Temperament was assessed using the Infant Behavioral and Early Childhood Behavioral Questionnaires. Microbial samples were collected from oral cavity at birth and the bacterial profiles were assessed using 16S rRNA gene sequencing. Microbial diversity was characterized using alpha and beta diversity metrics. Analyses were performed for the most abundant genera. The sample was analyzed as a whole, as well as divided into subgroups representing no antibiotic use during birth (n = 198) and those with antibiotic use during birth (n = 137). No significant associations were observed between microbial profiles and behavioral measures after Bonferroni corrections. Nevertheless, our pre-correction results indicated an association between increased behavioral temperament surgency in the first year and beta diversity (high abundance of Bacteroides, Faecalibacterium and Blautia, low abundance of Lactobacillus) in the antibiotic use group. Additionally, pre-corrections, a high relative abundance of Staphylococcus was associated with increased surgency through years 1, 2, and 3 in the no antibiotics group, prompting consideration into a possible link between antibiotic use and emerging behavioral temperament.

Early life adversity (ELA) and youth chronic health conditions have been examined as separate contributors to psychopathology. However, little work has specifically examined early life health adversity (ELHA) and its association with risk for internalizing disorders. This study seeks to examine the relationship between ELHA and internalizing disorders across adolescence. A sample of 705 Australian mother–youth dyads participated in a prospective longitudinal study. Mothers reported child health indicators at youth ages three-to-four days, six months, and five years and completed a psychiatric interview at 15 years. Youth completed a psychiatric interview, as well as measures of current health status, at age 20. ELHA was positively associated with both youth anxiety and depressive disorders from ages 15 to 20. When independently accounting for the role of (a) current health status and (b) exposure to traditionally conceptualized forms of ELA, these findings remained statistically significant for anxiety but not depressive disorders. ELHA interacted with maternal depression, such that ELHA was only associated with youth depressive disorders in cases where mothers themselves had experienced depression. Routine mental health screenings may be warranted for youth who experience ELHA and their mothers. Pediatric primary care may be an ideal setting for implementing prevention and intervention efforts.

Parental mentalization, as the ability to understand mental states (e.g., desires) behind their children’s actions, may play a relevant role in the prevention of future externalizing problems. We conducted a meta-analysis to examine the relationship between parental mentalization and children’s externalizing problems. Six electronic databases were searched for studies, published in English or Spanish, linking empirically those two variables. Participants included caregivers and children between 0 and 18 years. The filtering process yielded 42 studies with 52 effect sizes. Random-effect analysis revealed higher parental mentalization associated with fewer externalizing problems, with an effect size of r = −.19 (95% CI [−.25, −.13]). Due to high heterogeneity (I2 = 83.750), further analyses were conducted to explore factors affecting such association. Parenting experience and children’s developmental stage moderated the relationship, but approaches to operationalize mentalization (MM or PRF), sample type (clinical/at-risk vs. community), and reporting figure (primary caregiver vs. other informants) did not. The study highlights the significance of parental mentalization as a potential contributor to the prevention of externalizing behaviors among infants, children, and adolescents. Our findings may underscore practical implications for equipping caregivers with mentalization skills, helping them to answer appropriately to their children needs.

Infant sleep quality is increasingly regarded as an important factor for children long-term functioning and adaptation. The early roots of sleep disturbances are still poorly understood and likely involve a complex interplay between prenatal and postnatal factors. This study investigated whether exclusive breastfeeding during the first 6 months moderated the association between maternal prenatal pandemic-related stress (PRS) and sleep problems in 24-months children born during the COVID-19 pandemic. We also explored the potential contribution of maternal postnatal anxiety in these relations. Seventy-eight infants (50% males) and their mothers provided complete data from birth to 24 months. Between 12 and 48 h from birth, maternal PRS during pregnancy was retrospectively reported as well as maternal anxiety and exclusive breastfeeding. Maternal anxiety and exclusive breastfeeding were also reported at 3 and 6 months after childbirth. Children sleep disturbances were reported at 24 months. Bayesian analyses revealed that maternal PRS was positively associated with sleep problems in children who were not exclusively breastfed from birth to 6 months. Findings add to the growing literature on the lasting impact of early pre- and postnatal experiences on child well-being and development.

Rates of youth suicidal thoughts and behaviors (STBs) are rising, and younger age at onset increases vulnerability to negative outcomes. However, few studies have investigated STBs in early adolescence (ages 10–13), and accurate prediction of youth STBs remains poor. Network analyses that can examine pairwise associations between many theoretically relevant variables may identify complex pathways of risk for early adolescent STBs. The present study applied longitudinal network analysis to examine interrelations between STBs and several previously identified risk and protective factors. Data came from 9,854 youth in the Adolescent Brain Cognitive Development Study cohort (Mage = 9.90 ± .62 years, 63% white, 53% female at baseline). Youth and their caregivers completed an annual measurement battery between ages 9–10 through 11–12 years. Panel Graphical Vector Autoregressive models evaluated associations between STBs and several mental health symptoms, socioenvironmental factors, life stressors, and substance use. In the contemporaneous and between-subjects networks, direct associations were observed between STBs and internalizing symptoms, substance use, family conflict, lower parental monitoring, and lower school protective factors. Potential indirect pathways of risk for STBs were also observed. Age-specific interventions may benefit from prioritizing internalizing symptoms and early substance use, as well as promoting positive school and family support.

The transition from childhood to adolescence presents elevated risks for the onset of psychopathology in youth. Given the multilayered nature of development, the present study leverages the longitudinal, population-based Adolescent Brain Cognitive Development Study to derive ecologically informed risk/resilience profiles based on multilevel influences (e.g., neighborhood and family socioeconomic resources, parenting, school characteristics) and their transition pathways and examine their associations with psychopathology. Latent profile analysis characterized risk/resilience profiles at each time point (i.e., baseline, Year-1, Year-2); latent transition analysis estimated the most likely transition pathway for each individual. Analysis of covariance was used to examine associations between profile membership at baseline (i.e., ages 9–11) and psychopathology, both concurrently and at Year-2 follow-up. Further, we examined the associations between profile transition pathways and Year-2 psychopathology. Four distinct profiles emerged across time – High-SES High-Protective, High-SES Low-Protective, Low-SES High-Family-Risk, and Low-SES High-Protective. Despite reasonably high stability, significant transition over time among profiles was detected. Profile membership at baseline significantly correlated with concurrent psychopathology and predicted psychopathology 2 years later. Additionally, profile transition pathways significantly predicted Year-2 psychopathology, exemplifying equifinality and multifinality. Characterizing and tracing shifts in ecologically informed risk/resilience influences, our findings have the potential to inform more precise intervention efforts in youth.

The rates of anxiety and depression increase across adolescence, many experience recurrence after treatment, yet longitudinal studies examining promotive factors are scarce. We prospectively examined the role of the promotive factors structured style, personal and social competencies, family functioning, and social resources in homotypic and heterotypic continuity and discontinuity of anxiety and depression across three years in a clinical sample. Participants were adolescents with anxiety or depressive disorders aged 13–18 years at T1 (N = 717, 44% initial participation rate) and aged 16–21 years at T2 (N = 549, 80% follow-up participation rate). At T1, diagnoses were collected from medical records and participants responded to questionnaires. At T2, semi-structured diagnostic interviews were conducted. Higher levels of all promotive factors were associated with reduced probability of anxiety or depression three years later. The promotive factors were not associated with homotypic continuity of anxiety, whereas personal competence beliefs, social competence, and, less strongly, family functioning were associated with reduced homotypic continuity of depression and heterotypic continuity from depression to anxiety. Analyses with interaction terms did not indicate moderation by the promotive factors. Our findings suggest that bolstering promotive factors may be vital for increasing treatment success and preventing recurrence of anxiety and depression in the transition toward adulthood.

Research has shown experimentally that if children are taught to use language to create distance (socially, physically, and temporarily) when they revisit a potentially traumatic experience they reduce the intensity of their emotions. Building on this, this study was carried out to explore whether children with better spatial skills are better at such downregulation because of their very aptitude in understanding the concept of distance. Using data from a general-population birth cohort in the UK, the study examined the bidirectional association between emotional dysregulation and spatial ability among children aged 5 and 7 years. The findings reveal a significant reciprocal relationship even after adjusting for family, contextual, and individual confounders including verbal ability: spatial skills at age 5 years were inversely related to emotional dysregulation at age 7 years, and conversely, greater emotional dysregulation at age 5 years was associated with poorer spatial ability at age 7 years. The two paths were equally strong and there was no evidence of differences between them on the basis of sex. Our results suggest that enhancing spatial abilities could be a potential avenue for supporting emotion regulation in middle childhood.

Social camouflaging (SC) is a set of behaviors used by autistic people to assimilate with their social environment. Using SC behaviours may put autistic people at risk for poor mental health outcomes. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the goal of this systematic review was to investigate the development of SC and inform theory in this area by outlining the predictors, phenotype, and consequences of SC. This review fills a gap in existing literature by integrating quantitative and qualitative methodologies, including all gender identities/age groups of autistic individuals, incorporating a large scope of associated factors with SC, and expanding on theory/implications. Papers were sourced using Medline, PsycInfo, and ERIC. Results indicate that self-protection and desire for social connection motivate SC. Camouflaging behaviors include compensation, masking, and assimilation. Female individuals were found to be more likely to SC. Additionally, this review yielded novel insights including contextual factors of SC, interpersonal relational and identity-related consequences of SC, and possible bidirectional associations between SC and mental health, cognition, and age of diagnosis. Autistic youth and adults have similar SC motivations, outward expression of SC behavior, and experience similar consequences post-camouflaging. Further empirical exploration is needed to investigate the directionality between predictors and consequences of SC, and possible mitigating factors such as social stigma and gender identity.
