Pandemic play moderates the relation between caregiver stress and child emotional distress in contexts of economic adversity.

It is well-established that caregiver stress is linked to increased emotional distress among children, and recent evidence highlights similar associations between caregiver and child emotional well-being during the coronavirus (COVID-19) pandemic. Examining protective factors and coping mechanisms that are associated with resiliency in the face of pandemic-related stress can highlight potential strategies that may help children adapt to other unexpected hardships outside of a global pandemic. Previous research found that playing about the pandemic moderated an association between caregiver stress and children's emotional distress. However, few studies have explored "pandemic play" among children from low-income households, where pandemic-related stressors were often exacerbated. In the present study, 72 caregivers of Head Start preschoolers between 3 and 6 years of age were surveyed between late 2020 and early 2021. Results revealed that 32% of children engaged in pandemic play frequently. Caregiver stress was positively associated with child emotional distress, but only among children who did not engage in pandemic play frequently. These findings support the idea that child-directed play may be a developmentally appropriate and accessible coping mechanism to reduce the emotional burden of stressful events on children, regardless of economic context.

Spanish-English bilingual toddlers' vocabulary skills: The role of caregiver language input and warmth.

There is a well-documented link between bilingual language development and the relative amounts of exposure to each language. Less is known about the role of quality indicators of caregiver-child interactions in bilingual homes, including caregiver input diversity, warmth and sensitivity. This longitudinal study examines the relation between caregiver input (lexical diversity, amount), warmth and sensitivity and bilingual toddlers' subsequent vocabulary outcomes. We video-recorded caregiver-child interactions in Spanish-English Latino homes when toddlers (n = 47) were 18 months of age (M = 18.32 months; SD = 1.02 months). At the 24-month follow-up, we measured children's vocabulary as total vocabulary (English, Spanish combined) as well as within language (Spanish, English). Results revealed that Spanish lexical diversity exposure at 18 months from caregivers was positively associated with children's Spanish and total vocabulary scores at 24 months, while English lexical diversity was positively associated with children's English scores; lexical diversity and amount were highly correlated. Additionally, caregivers' warmth was positively associated with children's Spanish, English and total vocabulary scores. Together, these factors accounted for substantial variance (30-40%) in vocabulary outcomes. Notably, caregiver input accounted for more variance in single language outcomes than did caregiver warmth, whereas caregiver warmth uniquely accounted for more variance in total vocabulary scores. Our findings extend prior research findings by suggesting that children's dual language development may depend on their exposure to a diverse set of words, not only amount of language exposure, as well as warm interactions with caregivers. A video abstract of this article can be viewed at https://youtu.be/q1V_7fz5wog HIGHLIGHTS: Video-recorded observations of caregiver-child interactions revealed warmth and high sensitivity from Latino caregivers. Linguistically-detailed analyses of caregiver input revealed wide variation in the diversity of Spanish and English directed at 18-month-old bilingual toddlers. Bilingual toddlers' vocabulary (single language, total) was positively associated with caregivers' diverse input and warmth, thus extending prior findings on bilinguals' amount of language exposure. Findings suggest that caregivers' lexical diversity explains more variance in bilingual toddlers' single language outcomes, whereas warmth explains more variance in total vocabulary scores.

Child Adjustment During COVID-19: The Role of Economic Hardship, Caregiver Stress, and Pandemic Play.

The coronavirus disease 2019 (COVID-19) led to many lifestyle changes and economic hardships for families with young children. Previous research on risk and resilience highlights that children's adjustment to family hardships is influenced by caregiver stress, but individual child behaviors and characteristics may protect children from negative outcomes. Interestingly, many children have been reported to incorporate COVID-19 themes in their pretend play. Theory suggests children may do so to cope with pandemic-related stress, but no empirical studies have explored this possibility. The purpose of this study was to understand the process by which COVID-19 economic hardships experienced by a family were related to children's emotional well-being and development and to investigate how this process may vary as a function of children's engagement in pandemic-related pretend play. Caregivers (N = 99; mostly high earning families) of preschoolers ages 3-6 years (51% girls, 82% White) living in the United States participated in an online survey at two time points during the pandemic. Result revealed that COVID-19 economic hardships were related to increased caregiver stress, which, in turn, was associated with children's emotional distress and poorer self-regulation. However, engaging in pandemic-related pretend play appeared to protect children's well-being by weakening the adverse association between caregivers' stress and children's emotional distress. Thus, addressing caregiver stress levels and allowing children an outlet to cope with challenges through pretend play could have crucial protective effects on early development and well-being during times of crisis.

Health risk assessment of volatile organic compounds at daycare facilities.

Children are particularly vulnerable to many classes of the volatile organic compounds (VOCs) detected in indoor environments. The negative health impacts associated with chronic and acute exposures of the VOCs might lead to health issues such as genetic damage, cancer, and disorder of nervous systems. In this study, 40 VOCs including aldehydes and ketones, aliphatic hydrocarbons, esters, aromatic hydrocarbons, cyclic terpenes, alcohols, and glycol ethers were identified and qualified in different locations at the University of Missouri (MU) Child Development Laboratory (CDL) in Columbia, Missouri. Our results suggested that the concentrations of the VOCs varied significantly among classrooms, hallways, and playground. The VOCs emitted from personal care and cleaning products had the highest indoor levels (2-ethylhexanol-1, 3-carene, homomenthyl salicylate with mean concentration of 5.15 µg/m3 , 1.57 µg/m3 , and 1.47 µg/m3 , respectively). A cancer risk assessment was conducted, and none of the 95th percentile dose estimates exceeded the age-specific no significant risk levels (NSRL) in all classrooms. Dimensionless toxicity index scores were calculated for all VOCs using a novel web-based framework called Toxicological Prioritization Index (ToxPi), which integrates multiple sources of toxicity data. According to the method, homomenthyl salicylate, benzothiazole, 2-ethylhexyl salicylate, hexadecane, and tridecane exhibited diverse toxicity profiles and ranked as the five most toxic indoor VOCs. The findings of this study provide critical information for policy makers and early education professionals to mitigate the potentially negative health impacts of indoor VOCs in the childcare facilities.

Exposure to environmental toxicants and young children's cognitive and social development.

Background Understanding the role of environmental toxicant exposure on children's development is an important area of inquiry in order to better understand contextual factors that shape development and ultimately school readiness among young children. There is evidence suggesting negative links between exposure to environmental toxicants and negative physical health outcomes (i.e. asthma, allergies) in children. However, research on children's exposure to environmental toxicants and other developmental outcomes (cognitive, socioemotional) is limited. Objectives The goal of the current review was to assess the existing literature on the links between environmental toxicants (excluding heavy metals) and children's cognitive, socioemotional, and behavioral development among young children. Methods This literature review highlights research on environmental toxicants (i.e. pesticide exposure, bisphenol A, polycyclic aromatic hydrocarbons, tobacco smoke, polychlorinated biphenyls, flame retardants, phthalates and gas pollutions) and children's development across multiple domains. Results The results highlight the potential risk of exposure to multiple environmental toxicants for young children's cognitive and socioemotional development. Discussion Discussion will focus on the role of environmental toxicants in the cognitive and socioemotional development of young children, while highlighting gaps in the existing literature.

Economic hardship during infancy and U.S. Latino preschoolers' sociobehavioral health and academic readiness.

We tested a culturally integrative model examining the associations among economic hardship during infancy and Latino children's later sociobehavioral problems and academic skills prior to kindergarten entry, whether mothers' mental health problems and positive parenting behaviors mediated those associations, and whether they varied by mothers' acculturation levels. Participants were 714 low-income Latino mothers (M age at enrollment = 24 years; 82% Mexican American; 59% foreign-born) and children (M age at enrollment = 4 months; 53% boys) in the Early Head Start Research and Evaluation Project (EHSREP). Data were gathered across five time points: when the families enrolled in the EHSREP, when the children were 14, 24, and 36 months of age, and just prior to their kindergarten entry. The results revealed an inverse relation between economic hardship during infancy and academic skills prior to kindergarten entry, with the association mediated through maternal mental health problems and positive parenting behaviors. The association between economic hardship and children's sociobehavioral problems via maternal mental health problems and positive parenting behaviors, however, was not statistically significant. Instead, the positive relation between mothers' mental health problems and children's sociobehavioral problems was mediated by maternal positive parenting behaviors. The findings highlight key family processes by which economic hardship in infancy may be associated with Latino preschoolers' academic skills prior to entering school. (PsycINFO Database Record

Negative emotionality and discipline as long-term predictors of behavioral outcomes in African American and European American children.

The present study examined the early parenting and temperament determinants of children's antisocial and positive behaviors in a low-income, diverse ethno-racial sample. Participants were from the Early Head Start Research and Evaluation Project, which included 960 European American (initial M age = 15.00 months; 51.2% female) and 880 African American mothers and their children (initial M age = 15.10 months; 49.2% female) followed from 15 months of age to 5th grade. For European American children, findings showed direct and indirect effects (via self-regulation) of early negative emotionality on later behaviors. For African American children, discipline practices in infancy had direct long-term implications for behaviors in 5th grade. Discussion highlights the interplay of parenting, temperament, and culture from infancy to late childhood. (PsycINFO Database Record

The interplay of maternal sensitivity and toddler engagement of mother in predicting self-regulation.

Using data from the Early Head Start Research and Evaluation Project, a cross-lag mediation model was tested to examine longitudinal relations among low-income mothers' sensitivity; toddlers' engagement of their mothers; and toddler's self-regulation at ages 1, 2, and 3 years (N = 2,958). Age 1 maternal sensitivity predicted self-regulation at ages 2 and 3 years, and age 2 engagement of mother mediated the relation between age 1 maternal sensitivity and age 3 self-regulation. Lagged relations from toddler self-regulation at ages 1 and 2 years to later maternal sensitivity were not significant, suggesting stronger influence from mother to toddler than vice versa. Model fit was similar regardless of child gender and depth of family poverty. (PsycINFO Database Record

Preschool children with gender normative and gender non-normative peer preferences: psychosocial and environmental correlates.

We addressed several issues concerning children who show gender non-normative (GNN) patterns of peer play. First, do young children with GNN peer preferences differ from children with gender normative (GN) peer preferences in problem behaviors? Second, do GNN and GN children differ in sociability and isolation and do they have differential socialization opportunities with externalizing, internalizing, and socially competent peers? We employed a Bayesian approach for classifying children as GNN based on their peer preferences as compared to their peers using a sample of Head Start preschool children from a large Southwestern city (N = 257; 53 % boys; M age = 51 months; 66 % Mexican American). To calculate socialization opportunities, we assessed affiliation to each child in the class and weighted that by each peer's characteristics to determine the exposure that each child had to different kinds of peers. GN children of both sexes interacted more with same-sex peers, which may limit learning of different styles of interaction. As compared to GN children, GNN children exhibited more engagement in other-sex activities and with other-sex play partners and GNN children experienced somewhat fewer peer interactions, but did not differ on problem behaviors or social competence. Boys with GNN peer preferences had increased exposure to peers with problem behaviors. GNN girls experienced little exposure to peers with problem behaviors, but they also had little exposure to socially competent peers, which may reduce learning social skills from peers. Implications of these findings for future socialization and development will be discussed.

Preschoolers' academic readiness: What role does the teacher-child relationship play?

We examined the role of the teacher-child relationship quality (close, dependent, and conflictive) on preschoolers' (N = 95) academic readiness for kindergarten, and we tested children's prosocial and aggressive behavior and peer group exclusion as mediators of this relation. A unique feature of this study is the ethnically and socio-economically diverse preschool-aged sample. The association between close teacher-child relationships and academic readiness was partially mediated by prosocial behavior and peer group exclusion. There was also evidence of a transactional association between close teacher-child relationships and children's behavior. Additionally, children's behavior and peer group exclusion mediated the relation between negative teacher-child relationships (dependent and conflictive) and academic readiness. The findings suggest that teacher training, education, and support for establishing close teacher-child relationships may maximize preschoolers' academic readiness by promoting social adaptation.
