Nonstandard maternal work schedules: Implications for African American children's early language outcomes

In this study, observed maternal positive engagement and perception of work–family spillover were examined as mediators of the association between maternal nonstandard work schedules and children's expressive language outcomes in 231 African American families living in rural households. Mothers reported their work schedules when their child was 24 months of age and children's expressive language development was assessed during a picture book task at 24 months and with a standardized assessment at 36 months. After controlling for family demographics, child, and maternal characteristics, maternal employment in nonstandard schedules at the 24-month timepoint was associated with lower expressive language ability among African American children concurrently and at 36 months of age. Importantly, the negative association between nonstandard schedules and children's expressive language ability at 24 months of age was mediated by maternal positive engagement and negative work–family spillover, while at 36 months of age, the association was mediated only by negative work–family spillover. These findings suggest complex links between mothers’ work environments and African American children's developmental outcomes.     

Maternal employment, work schedules, and children's body mass index

Previous work has shown that mothers' employment is associated with increases in children's body mass index (BMI), a measure of weight for height. Nonstandard work (working evenings or nights, weekends, or an irregular shift) may also be associated with children's BMI. This article examines the association between maternal work and children's BMI and considers the influence of mothers' nonstandard work schedules. Using data from school-age children (approximately 8 to 12 years) in the NICHD's Study of Early Child Care and Youth Development (N = 990), this study found that an increase in the total time a mother is employed is associated with an increase in her child's BMI; additionally, the association between maternal employment and children's weight is much stronger at 6th grade relative to younger ages. There was no evidence that maternal or home characteristics or children's time use mediated these associations, nor was there any evidence that nonstandard work was associated with children's BMI. Implications for policy and future research are discussed.     

Maternal employment and child cognitive outcomes in the first three years of life: the NICHD Study of Early Child Care. National Institute of Child Health and Human Development

With increased numbers of women employed in their children's first year of life and with increased attention being paid by parents and policy makers to the importance of early experiences for children, establishing the links that might exist between early maternal employment and child cognitive outcomes is more important than ever. Negative associations between maternal employment during the first year of life and children's cognitive outcomes at age 3 (and later ages) have been reported using data from the National Longitudinal Survey of Youth-Child Supplement. However, it was not known whether these findings would be replicated in another study, nor whether these results were due to features of child care (e.g., quality, type), home environment (e.g., provision of learning), and/or parenting (e.g., sensitivity). This study explored these issues using data on 900 European American children from the National Institute of Child Health and Human Development Study of Early Child Care, which provides information on child cognitive scores at 15, 24, and 36 months, as well as data about the home environment (as assessed by the Home Observation of the Measurement of the Environment Scale), parental sensitivity, and child-care quality and type over the first 3 years of life. Maternal employment by the ninth month was found to be linked to lower Bracken School Readiness scores at 36 months, with the effects more pronounced when mothers were working 30 hr or more per week and with effects more pronounced for certain subgroups (i.e., children whose mothers were not sensitive, boys, and children with married parents). Although quality of child care, home environment, and maternal sensitivity also mattered, the negative effects of working 30 hr or more per week in the first 9 months were still found, even when controlling for child-care quality, the quality of the home environment, and maternal sensitivity. Implications for policy are also discussed.     

Child Care and Children's Peer Interaction at 24 and 36 Months: The NICHD Study of Early Child Care

Data from the National Institute of Child Health and Human Development Study of Early Child Care were examined to determine how children's experiences in child care were related to peer competence at 24 and 36 months of age, after controlling for the effects of family and child characteristics. Peer competence was assessed using mother and caregiver ratings as well as observations of children with their peers in child care, and at 36 months from observations of dyadic play with a familiar peer. Consistent, albeit modest, relations were found between child-care experiences in the first 3 years of life and children's peer competencies. Positive, responsive caregiver behavior was the feature of child care most consistently associated with positive, skilled peer interaction in child care. Children with more experience in child-care settings with other children present were observed to be more positive and skilled in their peer play in child care, although their caregivers rated them as more negative with playmates. Children who spent more hours in child care were rated by their caregivers as more negative in peer play, but their observed peer play was not related to the quantity of care. Child-care experiences were not associated with peer competence as rated by mothers or as observed in dyadic play with a friend. Maternal sensitivity and children's cognitive and language competence predicted peer competence across all settings and informants, suggesting that family and child-care contexts may play different, but complementary roles in the development of early emerging individual differences in peer interaction.     

Maternal Attitudes and Knowledge of Child-Rearing: Associations with Family and Child Outcomes

A prospective, longitudinal study of a low birthweight, preterm cohort examined the effects of maternal knowledge of child development and concepts of child rearing on the quality of home environment and on child cognitive and behavioral outcomes. Measures of maternal knowledge at 12 months were found to be significantly associated with the quality of the home environment, the number of child behavior problems, and to a small but significant extent child Stanford-Binet IQ at 36 months. Maternal characteristics were associated with both maternal knowledge and maternal behavior. Child characteristics, including birthweight, were not associated with maternal knowledge or concepts of development for most of the cohort. Subgroup analyses by race/ethnicity revealed a similar pattern of results. However, a measure of neonatal health status was shown to be significantly associated with cognitive outcome in the African-American subgroup at 24 and 36 months.     

Caregiver Responsiveness During Preschool Supports Cooperation in Kindergarten: Moderation by Children’s Early Compliance

Research Findings: The current study examined how children’s parent-reported compliance at age 3 (36 months) moderated the effects of 2 dimensions of directly observed early care and education (ECE) process quality (positivity/responsivity and cognitive stimulation) during the prekindergarten year (54 months) on teacher reports of children’s classroom cooperation in the fall of kindergarten. Compliance at 36 months and cooperation in kindergarten are operationalized as overt, behavioral aspects of self-regulation as appraised by parents and teachers. The sample consisted of 996 children from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development who attended formal or informal ECE settings during the prekindergarten year. Results indicated that children with low compliance at age 3 tend to demonstrate stronger cooperation skills by kindergarten when they experience more positivity/responsivity from their ECE caregivers. Main effects of positivity/responsivity and cognitive stimulation on classroom cooperation were not detected for the overall sample. Practice or Policy: The discussion addresses the importance of preparing and empowering ECE providers to help young children who enter the preschool period struggling with behavioral aspects of self-regulation, such as compliance, to improve these skills through positive and responsive caregiving.     

Relations between early family risk, children's behavioral regulation, and academic achievement

This study examined relations among early family risk, children's behavioral regulation at 54 months and kindergarten, and academic achievement in first grade using data on 1,298 children from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development. Family risk was indexed by ethnic minority status, low maternal education, low average family income from 1 - 54 months, and high maternal depressive symptoms from 1 - 54 months. Results of structural equation modeling indicated that minority status, low maternal education, and low family income had significant negative effects on reading, math, and vocabulary achievement in first grade. Modest indirect effects were also found from ethnicity, maternal education, and maternal depressive symptoms, through 54-month and kindergarten behavioral regulation to first-grade achievement. Discussion focuses on the importance of behavioral regulation for school success especially for children facing early risk.     

The relationship between child care subsidies and children's cognitive development

Child care subsidies help low-income families pay for child care while parents work or study. Few studies have examined the effects of child care subsidy use on child development, and no studies have done so controlling for prior cognitive skills. We use rich, longitudinal data from the ECLS-B data set to estimate the relationship between child care subsidy use and school readiness, using value-added regression models as well as parametric and non-parametric models with propensity score matching. Compared to a diverse group of subsidy non-recipients in various types of non-parental care as well as parental care only, we find that child care subsidy use during preschool is negatively associated with children's math skills at kindergarten entry. However, sensitivity analysis suggests that these findings could be easily overturned if unobserved factors affect selection into subsidy receipt.     

Neighborhood matters: racial socialization of African American children

Differences in racial socialization practices and their effects were examined in a sample of 241 African American 1st graders (average age 6.59 years) living in an urban area. Child outcomes included cognitive development, receptive language skills, and child problem behavior. The cultural environment of the home was associated with higher cognitive scores for boys living in high negative social climate and low social capital neighborhoods and for girls living in high social capital neighborhoods. The positive association of promotion of mistrust and child behavior problems was magnified in neighborhoods that had low levels of social capital. A high negative social climate in the neighborhood attenuated the positive association between preparation for bias/promotion of mistrust and externalizing problems.     

Resilience in young children involved with child protective services

Child maltreatment increases the risk of poor developmental outcomes. However, some children display resilience, meaning they are high-functioning despite their adverse experiences. To date, few research studies have examined protective factors among very young maltreated children. Yet, domains of resilience, and the protective factors that promote resilience among maltreated children, are likely to differ by developmental stage. Drawing on ecological systems theory and life course theory, we examined how protective factors at multiple ecological levels across early childhood were related to social and cognitive resilience among very young children involved with child protective services. The results demonstrated that the buffering effects of protective factors varied by social or cognitive resilience and the cumulative effects of protective factors were more consistently related to later resilience than protective factors at specific time points. In addition, the influence of specific protective factors on resilience slightly varied by initial in-home or out-of-home placement. These findings have important policy and research implications for promoting optimal development among children involved in child protective services.     

Effects of Residential Instability on Head Start Children and Their Relationships with Older Siblings: Influences of Child Emotionality and Conflict between Family Caregivers

This study examined the influence that residential dislocations have on child behavior problems, depression, peer competence, cognitive competence, and the quality of sibling relations in a sample of 70 Head Start children, aged 32 to 67 months, and their older brothers and sisters, aged 48 to 155 months. This was the first study to investigate the sibling relationship in the context of high residential mobility. Information on child characteristics was obtained from mothers and teachers. Sibling data (warmth/harmony and conflict) were obtained from coding videotaped interactions. Child emotionality was found to be an important moderator of the effects of residential mobility on young, poor children and their siblings; caregiver conflict was a less powerful moderator of these effects. Residential instability seemed to compromise the warmth/harmony of the sibling relationship. It was concluded that the effects of residential instability are complex and cannot be understood without considering child characteristics, such as temperament, and the family context in which the child lives.     

Maternal work conditions and child development

How do maternal work conditions, such as psychological stress and physical hazards, affect children's development? Combining data from the Child Development Supplement of the Panel Study of Income Dynamics and the Occupational Information Network allows us to shed some light on this question. We employ various techniques including OLS with extensive controls, a value added approach and individual fixed effects in order to address potential endogeneity problems. Our results reveal that mothers’ exposure to work-related hazards negatively affects children's cognitive development and to work-related stress negatively affects children's behavioral development. While maternal time investments play a small but significant role in mediating these negative associations, paternal time investments neither reinforce nor compensate these associations.     

The Effects of Infant Child Care on Infant-Mother Attachment Security: Results of the NICHD Study of Early Child Care NICHD Early Child Care Research Network

The aims of this investigation were to determine whether Strange Situation attachment classifications were equally valid for infants with and without extensive child-care experience in the first year of life and whether early Child Care experience, alone or in combination with mother/child factors, was associated with attachment security, and specifically with insecure-avoidant attachment. Participants were 1,153 infants and their mothers at the 10 sites of the NICHD Study of Early Child Care. Mother were interviewed, given questionnairies, and observed in play and in the home when their infants were from 1 to 15 months of age; infants were observed in child care at 6 and 15 months and in the Strange Situation at 15 months. Infants with extensive Child Care experience did not differ from infants without child-care in the distress they exhibited during separations from mother in the Strange situation or in the confidence with which trained coders assigned them attachment classifications. There were no significant main effects of Child Care experience (quality, amount, age of entry, stability, or type of care) on attachment security or avoidance. There were, however, significant man effects of maternal sensitivity and responsiveness. Significant interaction effects revealed that infants were less likely to be secure when low maternal sensitivity/responsiveness was combined with poor quality child care, more than minimal amounts of child care, or more than one care arrangement. In addition, boys experiencing many hours in care and girls in minimal amounts of care were somewhat less likely to be securely attachment.     

Mothers' time with infant and time in employment as predictors of mother-child relationships and children's early development

This study tested predictions from economic and developmental theories that maternal time with an infant is important for mother-child relationships and children's development, using time-use diaries for mothers of 7- to 8-month-old infants from the National Institute of Child Health and Human Development Study of Early Child Care (N = 1,053). Employment reduced time with infants, but mothers compensated for some work time by decreasing time in other activities. With family and maternal characteristics controlled, time with infants predicted high Home Observation for Measurement of the Environment (HOME) scores and maternal sensitivity, but bore little relation to children's engagement with mothers, secure attachment, social behavior, or cognitive performance from 15 to 36 months. Mothers who spent more time at work had higher HOME scores. Maternal time with infants may reflect maternal characteristics that affect both time allocation and maternal behavior.     

The impact of a Caribbean home-visiting child development program on cognitive skills

This paper provides a short-term impact evaluation of a home-visiting Early Child Development (ECD) program in the Caribbean aimed at vulnerable children from birth to three years. The analysis is based on a quasi-experimental research design including approximately four hundred children in treatment and comparable control communities. The differences-in-differences methodology estimates intention-to-treat effects. One year after implementation, we find no significant effects on the cognitive development of the average child, but pronounced differences by birth cohort. The program has significantly improved Fine Motor Skills and Visual Reception scores, related to early reading and writing abilities, of the youngest children aged below 18 months at program start. There is no program impact on the older cohort, whose cognitive development appears to be more strongly correlated with center-based ECD services. Language development has not improved for either cohort. The findings suggest that an early window of opportunities may exist for home-based programs.     

Early Home Environment and Mental Test Performance: A Structural Analysis

A theoretical model of early environment action was examined on a sample of 282 infants representing two racial groups (Caucasian, African-American). Children were obtained from three different sites in the United States. The model examined included the following variables: socioeconomic status (SES), early cognitive status (Bayley MDI at 12 months), stimulation within the home environment (subscales from the HOME Inventory at 12 and 24 months), parents use of negative control (subscales from the HOME Inventory at 12 and 24 months), and later cognitive status (36-month Stanford-Binet IQ). Structural Equation Modeling (SEM) with the LISREL software was used to confirm the fit of the model for African-Americans and Caucasians and for males and females separately. The models for males and females had similar structures, but not equal coefficients for all paths in the model. The models showed significant paths from socioeconomic status and early cognitive status to stimulation with the home environment, a significant path from SES to negative parental control, and a significant path from stimulation within the home environment to later cognitive status. The models for African-Americans and Caucasians differed in structure. For African-Americans, there was no evidence that the link between SES and 36-month IQ was mediated through negative control but SES and early cognitive status were linked to later IQ via the amount of stimulation provided in the home. For Caucasians, early cognitive status did not appear related to 36- month IQ but negative control did appear to mediate the relation between SES and IQ.     

Spoken language development in oral preschool children with permanent childhood deafness

This article documented spoken language outcomes for preschool children with hearing loss and examined the relationships between language abilities and characteristics of children such as degree of hearing loss, cognitive abilities, age at entry to early intervention, and parent involvement in children's intervention programs. Participants were evaluated using a combination of the Child Development Inventory, the Peabody Picture Vocabulary Test, and the Preschool Clinical Evaluation of Language Fundamentals depending on their age at the time of assessment. Maternal education, cognitive ability, and family involvement were also measured. Over half of the children who participated in this study had poor language outcomes overall. No significant differences were found in language outcomes on any of the measures for children who were diagnosed early and those diagnosed later. Multiple regression analyses showed that family participation, degree of hearing loss, and cognitive ability significantly predicted language outcomes and together accounted for almost 60% of the variance in scores. This article highlights the importance of family participation in intervention programs to enable children to achieve optimal language outcomes. Further work may clarify the effects of early diagnosis on language outcomes for preschool children.

Enhancing the Development of Low-Birthweight, Premature Infants: Changes in Cognition and Behavior over the First Three Years

The Infant Health and Development Program is a randomized clinical trial to test the efficacy of educational and family support services and pediatric follow-up offered in the first 3 years of life on reducing the incidence of developmental delay in low-birthweight (LBW), preterm infants in 8 clinical sites ( N = 985). Effects of the intervention on cognitive and behavior problem scores over the 3 years are examined. Significant intervention effects were seen on cognitive scores at 24 and 36 but not 12 months of age; effect sizes were similar at both ages. These effects persist when controlling for earlier cognitive scores. At 24 and 36 months, behavior problem scores for the intervention group were significantly lower than for the follow-up group; the intervention was more efficacious for children with higher initial behavior problem scores. Results are discussed in terms of timing and targeting of services for LBW and disadvantaged children.
