Early experience unpredictability in child development as a model for understanding the impact of the COVID-19 pandemic: A translational neuroscience perspective

Associations of sleep quality with war-related anxiety, childhood stressors, and war-related stressors in a sample of adult Israeli civilians during the Hamas-Israel war

The current study examined the sleep quality of Israeli adults following the onset of the Hamas-Israel war, and the associations of reduced sleep quality with the magnitude of war-related anxiety and exposure to adverse war-related events. We also examined whether exposure to stressors during childhood predicts a greater war-related reduction in sleep quality. 536 Israeli adults (mean age 31.4, 209 women) completed an online survey in January 2024, three months into the war. The survey included questionnaires assessing retrospectively childhood harshness (exposure to morbidity and mortality and low socioeconomic status), adverse childhood experiences, and childhood unpredictability. War anxiety was assessed via the war anxiety scale. The participants also completed the Pittsburgh Sleep Quality Index and the Insomnia Severity Index concerning two time points: (a) retrospectively, before the war, and (b) currently, during the war. Participants reported reduced sleep quality and increased symptoms of insomnia during the war. The magnitude of these changes was predicted by exposure to adverse war experiences both directly and indirectly through war-related anxiety. Poorer sleep quality and increased symptoms of insomnia were also indirectly predicted by childhood exposure to morbidity-mortality of close others and childhood unpredictability through greater war-related anxiety. Thus, exposure to the adverse experiences of war, as well as harsh and unpredictable childhoods, could hinder sleep quality during wartime, with these effects mediated by war-related anxiety.

Associations among environmental unpredictability, changes in resting-state functional connectivity, and adolescent psychopathology in the ABCD study

BACKGROUND

Unpredictability is a core but understudied dimension of adversities and has been receiving increasing attention recently. The effects of unpredictability on psychopathology and the underlying neural mechanisms, however, remain unclear. It is also unknown how unpredictability interacts with other dimensions of adversities in predicting brain development and psychopathology of youth.

METHODS

We applied cluster robust standard errors to examine how unpredictability was associated with the developmental changes in resting-state functional connectivity (rsFC) of large-scale brain networks implicated in psychopathology, as well as the moderating role of deprivation, using data from the Adolescent Brain Cognitive Development (ABCD) study, which included four measurements from baseline (mean ± s.d. age, 119.13 ± 7.51 months; 2815 females) to 3-year follow-up (N = 5885).

RESULTS

After controlling for threat, unpredictability was associated with a smaller increase in rsFC within default mode network (DMN) and a smaller decrease in rsFC between cingulo-opercular network (CON) and DMN. Neighborhood educational deprivation moderated the associations between unpredictability and changes in rsFC within DMN and fronto-parietal network (FPN), as well as between CON and DMN. A smaller decrease in rsFC between CON and DMN mediated the association between unpredictability and externalizing problems. Neighborhood educational deprivation moderated the indirect pathway from unpredictability to externalizing problems via a smaller decrease in CON-DMN rsFC.

CONCLUSIONS

Our findings shed light on the neural mechanisms underlying the associations between unpredictability and adolescents' psychopathology and the moderating role of deprivation, highlighting the significance of providing stable environment and abundant educational opportunities to facilitate optimal development.

Leveraging the science of early life predictability to inform policies promoting child health

Addressing the tremendous burden of early-life adversity requires constructive dialogues between scientists and policy makers to improve population health. Whereas dialogues focused on several aspects of early-life adversity have been initiated, discussion of an underrecognized form of adversity that has been observed across multiple contexts and cultures is only now emerging. Here we provide evidence for "why unpredictability?", including: 1. Evidence that exposures to unpredictability affect child neurodevelopment, with influences that persist into adulthood. 2. The existence of a translational non-human animal model of exposure to early life unpredictability that can be capitalized upon to causally probe neurobiological mechanisms. 3. Evidence that patterns of signals in the early environment promote brain maturation across species. 4. The uneven distribution of unpredictability across demographic populations that illuminates a possible focal point for enhancing health equity. We then outline the potential of unpredictability in terms of the "what"; that is, how might the concept of unpredictability be leveraged to inform policy? We emphasize the importance of interdisciplinary and community partnerships to the success of this work and describe our community-engaged research project. Finally, we highlight opportunities for the science of unpredictability to inform policies in areas such as screening, immigration, criminal justice, education, childcare, child welfare, employment, healthcare and housing.

Integrating developmental neuroscience with community-engaged approaches to address mental health outcomes for housing-insecure youth: Implications for research, practice, and policy

One in three children in the United States is exposed to insecure housing conditions, including unaffordable, inconsistent, and unsafe housing. These exposures have detrimental impacts on youth mental health. Delineating the neurobehavioral pathways linking exposure to housing insecurity with children's mental health has the potential to inform interventions and policy. However, in approaching this work, carefully considering the lived experiences of youth and families is essential to translating scientific discovery to improve health outcomes in an equitable and representative way. In the current paper, we provide an introduction to the range of stressful experiences that children may face when exposed to insecure housing conditions. Next, we highlight findings from the early-life stress literature regarding the potential neurobehavioral consequences of insecure housing, focusing on how unpredictability is associated with the neural circuitry supporting cognitive and emotional development. We then delineate how community-engaged research (CEnR) approaches have been leveraged to understand the effects of housing insecurity on mental health, and we propose future research directions that integrate developmental neuroscience research and CEnR approaches to maximize the impact of this work. We conclude by outlining practice and policy recommendations that aim to improve the mental health of children exposed to insecure housing.

Annual Research Review: Mapping the multifaceted approaches and impacts of adverse childhood experiences - an umbrella review of meta-analyses

Adverse childhood experiences (ACEs) significantly impact lifelong health and well-being. Despite extensive research, a comprehensive understanding of ACEs' multifaceted impacts continues to be challenging to achieve. This study synthesizes meta-analytic evidence to provide a comprehensive view of ACEs' effects, addressing various approaches to conceptualizing ACEs and their diverse outcomes. Employing an umbrella synthesis methodology, this review integrated findings from 99 meta-analyses involving 592 effect sizes. We examined ACEs through specificity, lumping, dimensional, and child maltreatment-centric approaches, assessing their impact across six domains: biological system dysregulation, neuropsychological impairments, physical health complications, mental health conditions, social and behavioral challenges, and criminal justice involvement. The findings reveal a small to moderate overall effect size of ACEs across outcome domains. Specific ACE approaches exhibited varying impact levels, with notable differences in effects on mental health, social/behavioral issues, and criminal justice involvement. When ACEs were aggregated without distinguishing between different types, but with consideration of their cumulative effects, adverse outcomes were significantly exacerbated. The child maltreatment-centric approach consistently demonstrated substantial effects across all evaluated domains. This review underscores the heterogeneity in ACEs' impacts, influenced by the type of ACE and specific outcomes considered. It highlights the necessity for comprehensive approaches to understanding, preventing, and mitigating the effects of ACEs. These insights are vital for developing targeted interventions and informing policy-making, emphasizing the complexity and varied nature of ACEs' influence on individual development and societal well-being.

Childhood unpredictability research within the developmental psychopathology framework: Advances, implications, and future directions

Greater unpredictability in childhood from the level of the caregiver-child dyad to broader family, home, or environmental instability is consistently associated with disruptions in cognitive, socioemotional, behavioral, and biological development in humans. These findings are bolstered by experimental research in non-human animal models suggesting that early life unpredictability is an important environmental signal to the developing organism that shapes neurodevelopment and behavior. Research on childhood unpredictability has surged in the past several years, guided in part by theoretical grounding from the developmental psychopathology framework (shaped largely by Dr. Dante Cicchetti's innovative work). The current review focuses on future directions for unpredictability research, including probing intergenerational effects, the role of predictability in resilience, cultural and contextual considerations, and novel developmental outcomes that should be tested in relation to childhood unpredictability. We urge the integration of multidisciplinary perspectives and collaborations into future research on unpredictability. We also provide ideas for translating this research to real-world practice and policy and encourage high-quality research testing whether incorporating predictability into interventions and policy improves developmental outcomes, which would support further dissemination of these findings.

A consensus statement on perinatal mental health during the COVID-19 pandemic and recommendations for post-pandemic recovery and re-build

Introduction

The COVID-19 pandemic posed a significant lifecourse rupture, not least to those who had specific physical vulnerabilities to the virus, but also to those who were suffering with mental ill health. Women and birthing people who were pregnant, experienced a perinatal bereavement, or were in the first post-partum year (i.e., perinatal) were exposed to a number of risk factors for mental ill health, including alterations to the way in which their perinatal care was delivered.

Methods

A consensus statement was derived from a cross-disciplinary collaboration of experts, whereby evidence from collaborative work on perinatal mental health during the COVID-19 pandemic was synthesised, and priorities were established as recommendations for research, healthcare practice, and policy.

Results

The synthesis of research focused on the effect of the COVID-19 pandemic on perinatal health outcomes and care practices led to three immediate recommendations: what to retain, what to reinstate, and what to remove from perinatal mental healthcare provision. Longer-term recommendations for action were also made, categorised as follows: Equity and Relational Healthcare; Parity of Esteem in Mental and Physical Healthcare with an Emphasis on Specialist Perinatal Services; and Horizon Scanning for Perinatal Mental Health Research, Policy, & Practice.

Discussion

The evidence base on the effect of the pandemic on perinatal mental health is growing. This consensus statement synthesises said evidence and makes recommendations for a post-pandemic recovery and re-build of perinatal mental health services and care provision.

The promotive and protective effects of parents' perceived changes during the COVID-19 pandemic on emotional well-being among U.S. households with young children: an investigation of family resilience processes

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.

Methods

This study drew data from the RAPID project, a large ongoing national study that used frequent online surveys to examine the pandemic impact on U.S. households with young children. A subsample of 669 families was leveraged for the current investigation, including 8.07% Black, 9.57% Latino(a), 74.44% non-Latino(a) White families, and 7.92% households of other racial/ethnic backgrounds. In this subsample, 26.36% were below 200% federal poverty level.

Results

Approximately half of the parents reported moderate-to-large degrees of changes during the pandemic, and the most prevalent domain of change was appreciation of life, followed by personal strengths, new possibilities, improved relationships, and spiritual growth. Black and Latino(a) parents reported more changes in all five domains than White parents and more spiritual growth than parents of the other racial/ethnic groups. Moreover, parent-reported improved relationships were found to indirectly reduce young children's overall fussiness/defiance and fear/anxiety symptoms through reducing parents' emotional distress. Perceived changes in the new possibilities, personal strengths, and appreciation of life domains were found to serve as protective factors that buffered the indirect impacts of material hardship mean levels on child behavioral symptoms via mitigating parents' emotional distress.

Discussion

These findings shed light on resilience processes of a family system in a large-scale, disruptive, and stressful socio-historical event such as the COVID-19 pandemic. The five PTG domains could inform therapeutic and intervention practices in the face of future similar events. Importantly, these findings and the evinced family resilience should not negate the urgent needs of policy and program efforts to address material hardships, financial instabilities, and race/ethnicity-based structural inequalities for families of young children.

COVID-19-related stress exacerbates the effect of child maltreatment on negative affect via increased identity confusion during adolescence

INTRODUCTION

Exposure to childhood maltreatment may undermine the crucial developmental task of identity formation in adolescence, placing them at risk for developing negative affect. The current study investigated whether COVID-19-related stress intensified the indirect link between child maltreatment and adolescents' negative affect through identity confusion.

METHOD

Using multidimensional assessments of child maltreatment (threat vs. deprivation), the study included a sample of 124 adolescents (Mage  = 12.89, SD = 0.79; 52% female) assessed before (January 2018 to March 2020) and during the pandemic (May to October 2020) in Georgia, United States. The majority of the participants were European American (78.8%), followed by African American (11.5%), Hispanic (3.8%), Asian/Pacific Islander (1.0%), and other (4.8%). We used structural equation modeling to test (a) the mediating role of identity confusion in the link between childhood maltreatment and negative affect and (b) whether COVID-19-related stress moderated these indirect effects. Simple slopes and Johnson-Neyman plots were generated to probe regions of significant interaction effects.

RESULTS

Threat and deprivation predicted an increase in adolescent identity confusion. Additionally, childhood threat and deprivation were indirectly linked to adolescents' negative affect through increased levels of identity confusion. COVID-19-related stress significantly exacerbated the link between identity confusion and negative affect.

CONCLUSION

Identity confusion is a mechanism underlying the link between child maltreatment and the development of negative affect in adolescence. Our results inform prevention and intervention programs that aim to reduce negative affect among adolescents who experience threatening and depriving rearing environments.

The Ecological Resilience Framework: The Justice Ambassadors Youth Council as a model for community-based resilience

We present an 'Ecological Resilience Framework' (ERF) to demonstrate how resilience is created through the Justice Ambassadors Youth Council (JAYC) program. JAYC is a platform in which New York government representatives collaboratively learn and develop policy solutions alongside emerging adults who are criminal legal system impacted and reside in predominantly Black and Hispanic communities characterized by chronically high levels of poverty, violence, and incarceration. We focus our work on the process of developing resilience in the context of structural social inequity and injustice. We argue that resilience can best be understood in the context of the adversity to which it is a response, not as an isolated individual quality. Therefore, resilience science is at its best when it incorporates a multi-disciplinary scientific perspective, one that addresses a continuum from individual- to community- to society-level physical, cognitive, relationship, and mental health variables. To demonstrate how our ERF incorporates this approach, we outline how JAYC not only supports young adult participants in understanding their individual life trajectories and narrative identity, but also actively connects them within a diverse social network of mentors and to various opportunities that support a healthy transition to adult resilience.

Exploring parent-engaged developmental monitoring of young children before and during the COVID-19 pandemic, Porter Novelli Styles 2019 and 2021

Background

Early identification of developmental delays may have been negatively impacted by the COVID-19 pandemic. Parental engagement in developmental monitoring is a key component to successfully identifying developmental concerns.

Objective

/Hypothesis.The purpose of this project was to understand whether parental engagement in developmental monitoring changed over the course of the COVID-19 pandemic, from Spring 2019 to Fall 2021.

Methods

Survey data was obtained from 2019 SpringStyles and 2021 FallStyles Porter Novelli Public Services ConsumerStyles cross-sectional surveys. Only respondents with at least one child under the age of 8 at the time of the survey were included in the analytic sample (2019 N = 403; 2021 N = 344). Participants were asked several questions about how they monitor their children’s development. Changes in frequency of developmental monitoring from 2019 to 2021 were estimated using chi-squared tests.

Results

In both 2019 and 2021, 89% of parents reported engaging in any type of developmental monitoring. Within the group of parents who engaged in any monitoring, there were no differences across years in the percentage of parents reporting using the methods surveyed, except that a smaller percentage reported comparing their children to others in 2021 (25%) compared to 2019 (36%, p <.002).

Conclusions

Despite major disruptions to families’ lives, there were no significant changes to parents’ overall engagement in developmental monitoring prior to and during the COVID-19 pandemic.

Exposure to unpredictability and mental health: Validation of the brief version of the Questionnaire of Unpredictability in Childhood (QUIC-5) in English and Spanish

Unpredictability is increasingly recognized as a primary dimension of early life adversity affecting lifespan mental health trajectories; screening for these experiences is therefore vital. The Questionnaire of Unpredictability in Childhood (QUIC) is a 38-item tool that measures unpredictability in childhood in social, emotional and physical domains. The available evidence indicates that exposure to unpredictable experiences measured with the QUIC predicts internalizing symptoms including depression and anxiety. The purpose of the present study was to validate English and Spanish brief versions (QUIC-5) suitable for administration in time-limited settings (e.g., clinical care settings, large-scale epidemiological studies). Five representative items were identified from the QUIC and their psychometric properties examined. The predictive validity of the QUIC-5 was then compared to the QUIC by examining mental health in four cohorts: (1) English-speaking adult women assessed at 6-months postpartum (N = 116), (2) English-speaking male veterans (N = 95), (3) English-speaking male and female adolescents (N = 155), and (4) Spanish-speaking male and female adults (N = 285). The QUIC-5 demonstrated substantial variance in distributions in each of the cohorts and is correlated on average 0.84 (r's = 0.81-0.87) with the full 38-item version. Furthermore, the QUIC-5 predicted internalizing symptoms (anxiety and depression) in all cohorts with similar effect sizes (r's = 0.16-0.39; all p's < 0.05) to the full versions (r's = 0.19-0.42; all p's < 0.05). In sum, the QUIC-5 exhibits good psychometric properties and is a valid alternative to the full QUIC. These findings support the future use of the QUIC-5 in clinical and research settings as a concise way to measure unpredictability, identify risk of psychopathology, and intervene accordingly.

The effects of early life adversity on children's mental health and cognitive functioning

Emerging evidence suggests that partially distinct mechanisms may underlie the association between different dimensions of early life adversity (ELA) and psychopathology in children and adolescents. While there is minimal evidence that different types of ELA are associated with specific psychopathology outcomes, there are partially unique cognitive and socioemotional consequences of specific dimensions of ELA that increase transdiagnostic risk of mental health problems across the internalizing and externalizing spectra. The current review provides an overview of recent findings examining the cognitive (e.g., language, executive function), socioemotional (e.g., attention bias, emotion regulation), and mental health correlates of ELA along the dimensions of threat/harshness, deprivation, and unpredictability. We underscore similarities and differences in the mechanisms connecting different dimensions of ELA to particular mental health outcomes, and identify gaps and future directions that may help to clarify inconsistencies in the literature. This review focuses on childhood and adolescence, periods of exquisite neurobiological change and sensitivity to the environment. The utility of dimensional models of ELA in better understanding the mechanistic pathways towards the expression of psychopathology is discussed, with the review supporting the value of such models in better understanding the developmental sequelae associated with ELA. Integration of dimensional models of ELA with existing models focused on psychiatric classification and biobehavioral mechanisms may advance our understanding of the etiology, phenomenology, and treatment of mental health difficulties in children and youth.

Family stress during the pandemic worsens the effect of adverse parenting on adolescent sleep quality

BACKGROUND

Adverse parenting is consistently associated with increased sleep problems among adolescents. Shelter-in-Place restrictions and the uncertainty linked to the Covid-19 pandemic have introduced new stressors on parents and families, adding to the risk for youth's sleep problems.

OBJECTIVE

Using multidimensional assessments of child maltreatment (CM; threat vs. deprivation), the present study examined whether parent-report and child-report of Covid-19 related stress potentiated the effect of CM on sleep problems among boys and girls.

PARTICIPANTS AND SETTING

The study focused on a sample of 124 dyads of adolescents (Mage = 12.89, SD = 0.79; 52% female) and their primary caregivers (93% mothers) assessed before and during the pandemic (May to October 2020).

METHOD

Data were obtained from both youth and their parents. Structural equation modeling (SEM) was used to test all study hypotheses. Simple slopes and Johnson-Neyman plots were generated to probe significant interaction effects.

RESULTS

Deprivation, but not threat, directly predicted increased sleep problems among boys during the pandemic. Additionally, elevation in Covid-19 stress (both parent and child report) intensified the link between CM (threat and deprivation) and sleep problems among boys.

CONCLUSION

Our findings inform prevention and intervention efforts that aim to reduce sleep problems among boys during stressful contexts, such as the Covid-19 pandemic.

Associations Between Childhood Stressors, COVID-19-Related Anxiety, and Sleep Quality of Adults During the Third Wave of the COVID-19 Pandemic in Israel

PURPOSE

Studies point to a persistent effect of the COVID-19 pandemic on sleep quality and mental health, including anxiety. Exposure to stressors during childhood increases the susceptibility to anxiety in later life. Given the negative effects of anxiety on sleep quality, the present study aimed to examine the associations between various childhood stressors and poor sleep quality of adults during the COVID-19 pandemic, and whether these associations are mediated by COVID-19-related anxiety.

PARTICIPANTS AND METHODS

A total of 586 participants aged 18-40 (mean age 27.53± 6.48 years, 301 females) were recruited to take part in an online survey conducted in Israel between February 7 and 15, 2021, during the third wave of the COVID-19 pandemic. Participants completed questionnaires assessing retrospectively adverse childhood experiences (ACEs), childhood harshness (indexed separately by exposure to morbidity and mortality and low socioeconomic status, SES), and childhood unpredictability. COVID-19-related anxiety was assessed using two items. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), and insomnia symptoms with the Insomnia Severity Index (ISI). Participants were asked to complete the ISI concerning two time points: (a) retrospectively, before the COVID-19 outbreak, and (b) currently, during the pandemic.

RESULTS

Path analysis indicated that poor sleep quality (PSQI) was directly and indirectly (through COVID-19-related anxiety) predicted by the number of ACEs and childhood morbidity-mortality exposure, directly predicted by childhood low SES, and indirectly predicted by childhood unpredictability. Insomnia symptoms increase (ISI) was indirectly predicted by the number of ACEs, childhood morbidity-mortality exposure, and childhood unpredictability.

CONCLUSION

ACEs as well as harsh and unpredictable childhood environments are predictive of poorer sleep during the COVID-19 pandemic. COVID-19-related anxiety mediates the effects of childhood stressors (other than low SES) on sleep. These findings may have clinical implications relevant to stressful periods in general.
