Positive parenting moderates associations between childhood stress and corticolimbic structure

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.

Early Life Adversity and Empathy: A Scoping Review of Past Research and Recommendations for Future Directions

Early life adversity (ELA) describes stressful experiences that may increase risk for psychopathology and impact emotion regulation and executive functioning systems. The influence of ELA on the development of empathy-the ability to understand and resonate with others' thoughts and emotions-remains understudied, despite the fact that empathy development relies on cognitive and emotional abilities often affected by ELA. This scoping review summarized 43 empirical articles on ELA and empathy to clarify the muddled literature and address limitations to inform future research. Across various operationalizations of ELA and empathy, 15 articles suggested that ELA was associated with increased empathy, 19 that ELA was associated with decreased empathy, and 12 pointed to a null association. ELA and empathy showed differing associations across developmental periods, with ELA being more related to higher affective empathy and lower cognitive empathy in youth and higher personal distress in adulthood. Categorization by type of adversity revealed a lack of studies on deprivation and environmental adversity, while examination of empathy operationalization revealed a need for the assessment of empathy components among youth and more task-based measures of empathy. Recommendations for future research include the need to (a) clarify operationalizations of ELA, (b) explore empathy components and naturalistic measures, and (c) focus on outcomes in adolescence. Continued efforts to understand the connection between ELA and empathy will provide valuable insight into the impact of adversity on socioemotional development and guide psychosocial interventions for individuals at risk for maladaptive outcomes following adverse childhood experiences.

Exploring the Role of Empathy in the Association Between Early Life Adversity and Antisocial Behavior

Early life adversity (ELA) refers to stressful childhood experiences such as neglect, abuse, and violence exposure that can profoundly shape behavior. While ELA is consistently linked to antisocial behavior (e.g., aggression, delinquency), the role of empathy in this connection is unclear. Empathy, the ability to understand and resonate with others' thoughts and emotions, is theoretically linked to antisocial behavior, but empirical work has produced mixed findings. We explore mediation and moderation frameworks to explain the ELA-antisociality link. Using an online sample of 165 adults, we examine three ELA dimensions (unpredictability, threat, and deprivation) and their association with antisocial behavior and empathy through an ecologically valid empathic accuracy task. We also compare this naturalistic measure of empathy with a popular self-report measure of empathy. Results did not support mediation with either operationalization of empathy (i.e., task or self-report), with no direct effects of ELA on empathy or of empathy on antisocial behavior. Empathic accuracy, however, moderated the association between antisocial behavior and both unpredictability and deprivation in childhood. At low levels of empathic accuracy, there was a significant link between adversity and antisocial behavior (unpredictability β = 0.38, p < 0.001, deprivation β = 0.41, p < 0.001). Empathic accuracy did not moderate an association between threat adversity and antisocial behavior. Notably, across all moderation models, associations were non-significant when the self-report measure of empathy was used. Findings suggest that empathy skills protect against antisocial behavior in the context of unpredictability and deprivation, highlighting the importance of considering dimensions of ELA and ecologically valid, naturalistic empathy measures. Understanding how variations in empathic abilities within ELA dimensions influence antisocial behavior has implications for targeted interventions and promoting emotional well-being in individuals exposed to adversity.

How childhood adversity affects components of decision making

Extreme and chronic adverse experiences in childhood are linked to disruptions in a wide range of behavioral processes, including self-regulation, increased risk taking, and impulsivity. One proposed mechanism for these effects is alterations in how children learn and use information about rewards and risk in their environment. This type of decision making is a complex and multifaceted process consisting of distinct subcomponents, each of which may have varying effects on behavior. Here, we conducted a systematic review of the literature examining how reward and risk related decision making is influenced by childhood adversity. We aimed to identify whether childhood adversity is associated with alterations in how children learn about value information and how they subsequently use that information to inform decisions. Results suggest adverse experiences in childhood primarily impacts how individuals prioritize avoidance of risk and leads to devaluation of rewards.

Early childhood stress and amygdala structure in children and adolescents with neurodevelopmental disorders

Children and adolescents with neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) may be more susceptible to early life stress compared to their neurotypical peers. This increased susceptibility may be linked to regionally-specific changes in the striatum and amygdala, brain regions sensitive to stress and critical for shaping maladaptive behavioural responses. This study examined early life stress and its impact on striatal and amygdala development in 62 children and adolescents (35 males, mean age = 10.12 years, SD = 3.6) with ASD (n = 14), ADHD (n = 28), or typical development (TD, n = 20) across two cohorts. We assessed stress from various sources, including from the family environment, loss of loved ones, social stress, and illness/injury. We further examined parenting styles as potential moderators of the effects of early life stress. Volumes of the striatum and amygdala were extracted using an automatic segmentation algorithm. Significant group differences in childhood stress exposure were observed (F = 3.29, df = 8, p = 0.002), with autistic children facing more early life stressors (social stress, illness/injury) compared to those with ADHD and neurotypical peers (both, p < 0.002). In autistic children, amygdala volumes were significantly associated with early life stress related to the familial environment, experiences of significant loss, and illness/injury (all, p < 0.03). Positive parenting moderated these effects. These findings suggest that autistic children are more likely to experience early life stress and exhibit region-specific changes in the amygdala, a key brain region implicated in emotional processing and stress responses. This underscores the need for targeted interventions to support autistic children in managing early life stress to potentially mitigate its impact on brain development.

Perspectives on Integrating Biological Assessments to Address the Health Effects of Childhood Adversities

ABSTRACT

A majority of adults in the United States (US) report a range of stressful and potentially traumatic childhood experiences (e.g., physical or sexual abuse, witnessing violence, neglect). Such adversities are associated with a range of mental (e.g., anxiety, mood, and behavioral difficulties) and physical (e.g., cardiovascular illnesses, diabetes, asthma) health problems. Increasingly, precision medicine approaches seek to prevent and treat such multifinal downstream health problems by identifying common etiological pathways (e.g., inflammation and immune pathways) and candidate biomarkers to target interventions. In this context, we review the rationale for continued research to identify biomarkers of childhood adversity. Building on the bioecological theory, we emphasize that individual neurobiological profiles develop within multiple ecological levels (individual, family, neighborhood, macrosocial) that confer both risk and protective factors that can attenuate or amplify biological effects of childhood adversity. Given the limited data on adversity-associated biomarkers for children and adolescents, we discuss future recommendations for research, implications for clinical care, and ethical considerations. Preventing childhood adversity and supporting adversity- and trauma-informed systemic intervention approaches remains our primary recommendation. We highlight the continued need to consider both biomarkers of risk and protective factors across ecological levels in future research.

Integrating data science and neuroscience in developmental psychopathology: Formative examples and future directions

This commentary discusses opportunities for advancing the field of developmental psychopathology through the integration of data science and neuroscience approaches. We first review elements of our research program investigating how early life adversity shapes neurodevelopment and may convey risk for psychopathology. We then illustrate three ways that data science techniques (e.g., machine learning) can support developmental psychopathology research, such as by distinguishing between common and diverse developmental outcomes after stress exposure. Finally, we discuss logistical and conceptual refinements that may aid the field moving forward. Throughout the piece, we underscore the profound impact of Dr Dante Cicchetti, reflecting on how his work influenced our own, and gave rise to the field of developmental psychopathology.

Widening Our Lane: How Child and Adolescent Psychiatrists Can Embrace the Full Spectrum of Mental Health

The majority of a psychiatrist's training and clinical attention is devoted to mental illness rather than mental health. This article suggests a broader understanding and application of mental well-being that can benefit both those already struggling with mental health challenges and those trying to stay well. Recommendations for being a well-being-oriented psychiatrist include increasing one's knowledge about well-being and health promotion and adjusting one's practice to incorporate these principles. Recommendations at the level of the field of psychiatry include revising the definition of a psychiatrist, increasing research on well-being and health promotion, improving financial incentives, expanding efforts in schools and community settings, and providing additional training.

Leveraging the developmental neuroscience of caregiving to promote resilience among youth exposed to adversity

Early adversity is a major risk factor for the emergence of psychopathology across development. Identifying mechanisms that support resilience, or favorable mental health outcomes despite exposure to adversity, is critical for informing clinical intervention and guiding policy to promote youth mental health. Here we propose that caregivers play a central role in fostering resilience among children exposed to adversity via caregiving influences on children's corticolimbic circuitry and emotional functioning. We first delineate the numerous ways that caregivers support youth emotional learning and regulation and describe how early attachment lays the foundation for optimal caregiver support of youth emotional functioning in a developmental stage-specific manner. Second, we outline neural mechanisms by which caregivers foster resilience-namely, by modulating offspring corticolimbic circuitry to support emotion regulation and buffer stress reactivity. Next, we highlight the importance of developmental timing and sensitive periods in understanding caregiving-related mechanisms of resilience. Finally, we discuss clinical implications of this line of research and how findings can be translated to guide policy that promotes the well-being of youth and families.
