Article Synopsis
  • Adverse experiences during development can lead to negative long-term effects, but the neurobiological mechanisms behind this remain unclear, particularly during the adolescent brain's growth phase.
  • Two main frameworks are used to understand adversity: the cumulative risk model, which combines all types of negative experiences, and the dimensional model, which focuses on specific types, such as threat or deprivation, that have different effects on the brain.
  • A study of 179 adolescent girls found that categorizing adversity by specific dimensions of threat and deprivation better predicted brain changes than considering overall adversity; however, these dimensions did not show distinct relationships with brain development changes.

Introduction: The COVID-19 pandemic may constitute a traumatic event for families with young children due to its acute onset, the unpredictable and ubiquitous nature, and the highly distressing disruptions it caused in family lives. Despite the prevalent challenges such as material hardships, child care disruptions, and social isolation, some families evinced remarkable resilience in the face of this potentially traumatic event. This study examined domains of changes perceived by parents of young children that were consistent with the post-traumatic growth (PTG) model as factors that facilitate family resilience processes.

While there are some regulatory assessment criteria available on how to generally evaluate dermal absorption (DA) studies for risk assessment purposes, practical guidance and examples are lacking. The current manuscript highlights the challenges in interpretating data from in vitro assays and proposes holistic data-based assessment strategies from an industry perspective. Inflexible decision criteria may be inadequate for real data and may lead to irrelevant DA estimates.

Objectives: Children with neurodevelopmental delays show higher levels of externalizing behavioral problems, resulting in increased parental stress. This study aims to determine if the frequency of family routines moderates children's externalizing problems and associated parental stress based on children's cognitive ability longitudinally.

Methods: Children with neurodevelopmental delays and caregivers ( = 202) participated in assessments that included the Wechsler Preschool and Primary Scale of Intelligence-Forth Edition, Child Behavior Checklist, Parent Daily Report, and Family Routines Inventory.

Parents of young children were a subgroup of the population identified early in the pandemic as experiencing significant mental-health symptoms. Using a longitudinal sample of 3,085 parents from across the United States who had a child or children age 0 to 5, in the present study, we identified parental mental-health trajectories from April to November 2020 predicted by pre-COVID-19 cumulative risk and COVID-19-specific risk factors. Both growth-mixture modeling and latent-growth-curve modeling were used to test the relationship between risk factors and parent mental health.

Article Synopsis
  • * Structural issues in health care systems, alongside societal factors, disproportionately affect marginalized groups, such as people of color and those in rural or low-income areas, making it harder for them to receive care.
  • * An interprofessional team is testing a new preventive intervention called Center M, which integrates mindfulness-based cognitive therapy to increase accessibility and appeal for perinatal depression treatment, while also addressing existing barriers in standard prenatal care.

Young children from low-SES backgrounds are at higher risk for delayed language development, likely due to differences in their home language environment and decreased opportunities for back and forth communicative exchange. Intervention strategies that encourage reciprocal caregiver-child interactions may effectively promote young children's language development and enhance optimal language outcomes. The Filming Interactions to Nurture Development (FIND) program is a brief strength-based video-coaching intervention designed to promote increased back and forth ("serve and return") interactions between caregivers and their children.

Dermal absorption values are used to translate external dermal exposure into potential systemic exposure for non-dietary risk assessment of pesticides. While the Environmental Protection Agency of the United States of America (US EPA) derives a common dermal absorption factor for active substances covering all related products, the European Food Safety Authority (EFSA) requests specific product-based estimates for individual concentrations covering the intended use rates. The latter poses challenges, because it disconnects exposure dose from applied dose in absorption studies, which may not be suitable in scenarios where concentration is not relevant.

The dermal absorption potential of C-Caffeine applied as a 4 mg/mL concentration (10 μL/cm finite dose) was investigated in six laboratories under Good Laboratory Practice conditions using an OECD TG 428-compliant in vitro assay with flow-through cells and split-thickness human skin. Potential sources of variation were reduced by a standardized protocol, test item and skin source. Particularly, skin samples from same donors were distributed over two repeats and between labs in a non-random, stratified design.

Objectives: Adolescents in foster care may exhibit differential patterns of brain functioning that contribute to their pervasive socioemotional challenges. However, there has been limited investigation of implicated neural processes, particularly in the social domain. Thus, the current study investigated neural responses to exclusionary and inclusionary peer interactions in adolescents in foster-care.

Extensive evidence links adverse experiences during childhood to a wide range of negative consequences in biological, socioemotional, and cognitive development. Unpredictability is a core element underlying most forms of early adversity; it has been a focus of developmental research for many years and has been receiving increasing attention recently. In this article, we propose a conceptual model to describe how unpredictable and adverse early experiences affect children's neurobiological, behavioral, and psychological development in the context of the COVID-19 pandemic.

Children with developmental delays or disabilities (DD) are at risk for self-regulation difficulties and behaviour problems compared to typically developing children. Intervening early is crucial to prevent long-term adjustment challenges across home and school contexts. Parenting has been identified as a malleable target of intervention for improving children's adaptive functioning across behavioural, emotional and cognitive domains.

Objective: This study examined how the COVID-19 pandemic differently affected households of children with versus without special healthcare needs. We compared caregivers' and children's emotional well-being (Aim 1), the utilization of preventive healthcare services for young children (Aim 2), and the promotive effects of social support on well-being outcomes (Aim 3) during the pandemic between the two groups.

Methods: Data were drawn from an ongoing, large, longitudinal, and national survey that assessed the pandemic impact on households of young children (0-5).

Certain neural processes that underlie addiction are also central to parenting, notably stress and reward. Parenting interventions that incorporate the unique context of caregivers with addiction have demonstrated some success: However, real-world implementation of evidence-based interventions can be difficult with this population. Video feedback interventions are an especially promising approach to reach parents who experience barriers to participation, particularly caregivers with addiction.

Many existing preventive intervention programs focus on promoting responsive parenting practices. However, these parenting programs are often long in duration and expensive, and meta-analytic evidence indicates that families facing high levels of adversity typically benefit less. Moreover, due to a lack of specification and evaluation of conceptual models, the mechanisms underlying program-related changes in caregivers and their children often remain unclear.

Article Synopsis
  • Most children in U.S. foster care have experienced maltreatment or instability in caregiving, which negatively impacts their development, particularly in areas like neurobiology and behavior.
  • This study focused on toddlers in foster care and found that they exhibited greater right alpha EEG asymmetry compared to a low-income community group without foster care history.
  • However, the study did not find clear relationships between EEG asymmetry and behaviors such as internalizing or externalizing issues, emphasizing the need for deeper exploration of brain-behavior connections after early adversity.

Characterizing typologies of childhood adversity may inform the development of risk profiles and corresponding interventions aimed at mitigating its lifelong consequences. A neurobiological grounding of these typologies requires systematic comparisons of neural structure and function among individuals with different exposure histories. Using seed-to-whole brain analyses, this study examined associations between childhood adversity and amygdala resting-state functional connectivity (rs-fc) in adolescents aged 11-19 years across three independent studies (N = 223; 127 adversity group) in both general and dimensional models of adversity (comparing abuse and neglect).

This study examined children's stress system reactivity via the autonomic nervous system (ANS) and hypothalamic pituitary adrenal axis (HPAA) during an acute stressor as moderators of predicted relations between cumulative risk (CR) and mental health symptoms in a sociodemographically diverse sample of young children (n = 58). We employed a reliable stressor paradigm to allow assessment of individual differences in respiratory sinus arrhythmia (RSA) and pre-ejection period (PEP), indexing ANS reactivity, and salivary cortisol, indexing HPAA reactivity. Children's behaviours were assessed using the Child Behaviour Checklist (CBCL).

This study examined how individual differences in expectations of social consequences relate to individuals' expected involvement in health-risk behaviors (HRBs). A total of 122 adolescents (aged 11-17) reported their expected involvement in a number of risk behaviors and whether or not they expect to be liked more or less by engaging in the behavior: the expected social benefit. Higher perceived social benefit was associated with higher anticipated involvement in said behavior.

A growing number of early childhood (EC) parenting programs target adult executive function (EF) to build responsive parenting behaviors and to promote positive child development. Although measurement of EF is well understood in academic research, little work has examined EF measurement in community settings. The present study examined psychometric properties of the Behavior Rating Inventory of Executive Function-Adult Version among 203 parents whose children were enrolled in EC programs serving under-resourced communities.

Although the Children's Behavior Questionnaire (CBQ; Rothbart, Ahadi, Hershey, & Fisher, 2001) is the most popular assessment for childhood temperament, its psychometric qualities have yet to be examined using Item Response Theory (IRT) methods. These methods highlight in detail the specific contributions of individual items for measuring different facets of temperament. Importantly, with 16 scales for tapping distinct aspects of child functioning (195 items total), the CBQ's length can be prohibitive in many contexts.
