Predicting adolescent and young adult outcomes from emotional support and cognitive stimulation offered by preschool-age home and early care and education settings.

Children's early environmental experiences are often considered highly influential for later life development. Yet, environmental contexts, such as the home and early care and education (ECE) setting, and multiple aspects of each setting, are not typically examined concurrently. In this study, we examined associations between cognitive stimulation and emotional support in the home and ECE setting during the preschool years (36-54 months) with adolescent (age 15; n = 708; 52% female) and adult (age 26; n = 584; 54% female) outcomes using data from the Study of Early Child Care and Youth Development, a study conducted at 10 sites across the United States. Cognitive stimulation in the home was significantly related to increased academic achievement at age 15 and educational attainment at age 26. Home emotional support was related to decreased behavior problems and increased social skills at age 15. No significant associations were found between either emotional support or cognitive stimulation in ECE and children's later development. These findings provide further support that the child's home environment during early childhood plays a substantial role in development. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Early care and education.

This chapter briefly reviews the history of early care and education (ECE) in the United States, the ECE conceptual frameworks, how ECE is organized, who uses ECE, and associations between ECE experiences and child outcomes. Nonparent care is now experienced by most children in the United States, with home-based care most common for infants and toddlers and center-based care for preschoolers. ECE settings that involve frequent and responsive teacher-child interactions and access to age-appropriate activities appear to promote children's cognitive and social development, although those associations tend to be quite modest. Publicly funded programs like Head Start and pre-kindergarten programs tend to serve children from low-income families, and are successful in promoting school readiness skills, especially early academic skills. However, the impacts of today's programs largely disappear in the first years of elementary school, and even flipped from being positive to negative in the methodologically most rigorous studies. Explanations for this fadeout are explored.

Do more hours in center-based care cause more externalizing problems? A cross-national replication study.

Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in center-based care predicted changes in externalizing problems in toddlers and preschoolers (N = 10,105; 49% female; data collection 1993-2012) in seven studies, including from Germany, Netherlands, Norway, two from Canada and two from the U.S. Race/ethnicity data were only collected in the United States (57% and 80% White; 42% and 13% African-American; 1.2% and 5% Latinx). Meta-analyses showed no association (r = .00, p = .88) between hours in center-based care and externalizing problems.

Examining three hypotheses for pre-kindergarten fade-out.

Pre-kindergarten (Pre-K) programs typically improve early academic skills, but those gains too often disappear after children transition to elementary school. At least three hypotheses explain this "fade-out" of Pre-K effects: Pre-K does not focus on the "trifecta skills" that uniquely support subsequent learning and development; the quality of school-age experiences as "sustaining environments" are more important for Pre-K attenders than nonattenders; and kindergarten (K) teachers provide "redundant instruction" by teaching the same skills taught in preschool programs. The present sample included the second year of assessments on 455 children living in rural counties in the Southeast recruited from Pre-K classrooms and the first year of assessments for 246 K classmates without center-based preschool experience. Children's academic, language, executive function (EF), and social skills were assessed each fall and spring, and the quality of classrooms was measured each winter. Propensity scores weighted the two groups on demographic characteristics. Hierarchical linear models indicated that the Pre-K attenders had higher levels of language, academic, and EF skills than nonattenders at the beginning of K, but those differences significantly declined for academic skills. By the end of K, the Pre-K group showed slightly higher language and EF skills than the nonattenders. Results appeared to support the trifecta skills hypothesis to explain fade-out, with no evidence supporting the differential sustaining environments or redundant instruction hypotheses. Implications and the study's limitations are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The Educare intervention: Outcomes at age 3.

The effectiveness of Educare, a center-based early education program, in improving child outcomes at age 3 was evaluated in a randomized clinical trial. Educare programs serve children from birth to age 5 and are designed to reduce the achievement gap between children from low-income families and their more advantaged peers. This study began following 239 children from low-income families who were randomly assigned as infants (<19 months) to Educare or a business-as-usual control group. At age 3, assessments of the skills of 202 children remaining in the study revealed significant differences in favor of children in the treatment group on auditory language skills, early math skills, and parent-reported problem behaviors. Effect sizes were in the modest range, although not as strong as the previously reported age 2 findings. No effects were found for observations of parent-child interactions, observer-rated child behaviors, or parent-rated social competence. For English-language skills, children who were dual language learners (DLLs) benefitted more from treatment than non-DLLs. Analyses of outcomes by child care type, regardless of treatment group assignment, showed that children in Educare had better language, math, and behavioral scores than children in less formal care, whereas children in other center-based care only had higher language scores than children in less formal care. Differences in outcomes between Educare and other center-based care were not significant.

The Relation Between Classroom Age Composition and Children's Language and Behavioral Outcomes: Examining Peer Effects.

Grouping children of different ages in the same preschool classroom (i.e., mixed age) is widespread, but the evidence supporting this practice is mixed. A factor that may play a role in the relation between classroom age composition and child outcomes is peer skill. This study used a sample of 6,338 preschoolers (ages 3-5) to examine the influence of both classroom age composition and peer skill on children's behavioral and language outcomes. Results supported the growing literature indicating preschoolers' skills are higher when peer skill is higher, but differences related to classroom age composition were not found. These findings further support the view that peer skill plays an important role in preschool children's outcomes.

Health Status of Children Enrolled in a Family Navigator Program to Eliminate Intergenerational Poverty.

In 2014, Family Success Alliance (FSA) was formed as a place-based initiative to build a pipeline of programs to reduce the impact of poverty on outcomes for children living in Orange County, North Carolina. In this study, FSA parents' perception of child health, parent and child adverse childhood experiences (ACEs), and resilience were obtained by parent interview. Receipt of recommended health services were abstracted from primary care medical records of FSA children. Correlation coefficients investigated relationships among health, ACEs, and resilience. Among 87 parent-child dyads, 65% were Spanish speaking. At least 1 of the 7 ACEs measured was reported in 37% of children and 70% of parents. Parent perceptions of child health were lower than national averages. Routine preventive services included the following: autism screening at 18 months (15%) and 24 months (31%); ≥4 fluoride varnish applications (10%); lead screening (66%); and receipt of immunizations (94%). Parent perception of child health was moderately correlated with resilience.

Peer effects on low-income children's learning and development.

Using data from a large study of 78 high-quality Head Start classrooms in 12 sites across the U.S., this study examined whether peers' receptive vocabulary skills and teacher-reported social-emotional (S-E) functioning (i.e., behavior problems and self-regulation) measured at the beginning of the preschool year were related to children's gains in these three domains over a school year. Analyses included over 75% of the children in each classroom and produced three noteworthy findings. First, children in classrooms where average peers had higher behavior problems demonstrated increased teacher-reported behavior problems themselves at the end of the year. Second, children in classrooms where average peers had higher self-regulation skills demonstrated larger gains in teacher-reported self-regulation skills at the end of the school year. Third, peers' higher baseline self-regulation skills were found to be associated with children's higher self-regulation in spring, especially when children began the school year with higher levels of self-regulation. This finding indicates that children who have higher baseline self-regulation may be better positioned to benefit from their peers' high self-regulation in developing their own self-regulation skills. In contrast, no evidence was found that peers' baseline receptive vocabulary skills were related to children's receptive vocabulary gains over a school year. Additionally, no significant cross-domain peer effects were found between peers' baseline S-E functioning and children's receptive vocabulary gains nor peers' baseline receptive vocabulary skills and children's S-E development over a school year. Implications of these findings for classroom practice and further research are discussed.

Boosting School Readiness: Should Preschool Teachers Target Skills or the Whole Child?

We use experimental data to estimate impacts on school readiness of different kinds of preschool curricula - a largely neglected preschool input and measure of preschool quality. We find that the widely-used "whole-child" curricula found in most Head Start and pre-K classrooms produced higher classroom process quality than did locally-developed curricula, but failed to improve children's school readiness. A curriculum focused on building mathematics skills increased both classroom math activities and children's math achievement relative to the whole-child curricula. Similarly, curricula focused on literacy skills increased literacy achievement relative to whole-child curricula, despite failing to boost measured classroom process quality.

Vicarious Effort-Based Decision-Making in Autism Spectrum Disorders.

This study investigated vicarious effort-based decision-making in 50 adolescents with autism spectrum disorders (ASD) compared to 32 controls using the Effort Expenditure for Rewards Task. Participants made choices to win money for themselves or for another person. When choosing for themselves, the ASD group exhibited relatively similar patterns of effort-based decision-making across reward parameters. However, when choosing for another person, the ASD group demonstrated relatively decreased sensitivity to reward magnitude, particularly in the high magnitude condition. Finally, patterns of responding in the ASD group were related to individual differences in consummatory pleasure capacity. These findings indicate atypical vicarious effort-based decision-making in ASD and more broadly add to the growing body of literature addressing social reward processing deficits in ASD.

Child and Parenting Outcomes After 1 Year of Educare.

Educare is a birth to age 5 early education program designed to reduce the achievement gap between children from low-income families and their more economically advantaged peers through high-quality center-based programming and strong school-family partnerships. This study randomly assigned 239 children (< 19 months) from low-income families to Educare or a business-as-usual control group. Assessments tracked children 1 year after randomization. Results revealed significant differences favoring treatment group children on auditory and expressive language skills, parent-reported problem behaviors, and positive parent-child interactions. Effect sizes were in the modest to medium range. No effects were evident for observer-rated child behaviors or parent-rated social competence. The overall results add to the evidence that intervening early can set low-income children on more positive developmental courses.

Early child care and adolescent functioning at the end of high school: Results from the NICHD Study of Early Child Care and Youth Development.

Relations between early child care and adolescent functioning at the end of high school (EOHS; M age = 18.3 years) were examined in a prospective longitudinal study of 1,214 children. Controlling for extensive measures of family background, early child care was associated with academic standing and behavioral adjustment at the EOHS. More experience in center-type care was linked to higher class rank and admission to more selective colleges, and for females to less risk taking and greater impulse control. Higher quality child care predicted higher academic grades and admission to more selective colleges. Fewer hours in child care was related to admission to more selective colleges. These findings suggest long-term benefits of higher quality child care, center-type care, and lower child-care hours for measures of academic standing at the EOHS. (PsycINFO Database Record

I. QUALITY THRESHOLDS, FEATURES, AND DOSAGE IN EARLY CARE AND EDUCATION: INTRODUCTION AND LITERATURE REVIEW.

This monograph addresses the hypotheses that preschool children benefit most strongly when early care and education (ECE) is at or above a threshold of quality, has specific quality features, and/or is of longer duration. These issues are pivotal in recent policies designed to improve the quality of ECE, especially for children from low-income families. Evidence of quality thresholds in which ECE quality has stronger impacts in settings with moderate to high levels of quality than in settings with low quality would inform policy initiatives in which monetary incentives or consequences are allocated to ECE settings based on their level of quality. Evidence that specific features of quality, such as quality of teacher-child interactions and of literacy and mathematics instruction, are predictors of gains in child outcomes could help inform quality improvement efforts. Evidence that more time spent in center-based ECE or in instruction in specific content areas predict larger gains among preschoolers could be useful in designing public preschool programs such as Head Start or prekindergarten. Secondary data analyses of eight large studies of preschool children in center-based ECE were conducted. Analyses focused on quality thresholds and quality features examined the extent to which three types of quality measures predicted gains in children's language, literacy, mathematics, and social skills. The measures comprised (1) global quality measures that provide an overall or global rating of quality, focusing on interactions as well as on physical features of the environment, activities, and routines; (2) interaction-specific measures that focus in depth on the quality of interactions between teachers and children with respect to instructional and emotional support; and (3) domain-specific measures that focus on the quality of instruction and stimulation in specific content areas such as early language and literacy. The goal was to provide replicated analyses with data from several projects in order to address each question. Multilevel analyses that controlled for entry skills were conducted, and results were combined by using meta-analysis, nonlinear and nonparametric analyses, and propensity score analyses. With respect to thresholds, the analyses suggest that increases in the quality of instruction are related to larger gains in language and literacy outcomes, but only in higher quality classrooms. Results point to stronger associations between quality and child outcomes in higher versus lower quality classrooms for measures of the instructional quality of teacher-child interactions and of the quality of specific activities thought to promote early literacy, such as teaching phonemic skills and book reading. In addition, the items focusing on quality of interactions on the global measure also predicted acquisition of language and social skills in higher but not in lower quality classrooms. With respect to quality features, interaction-specific and especially domain-specific measures of quality remained significant predictors of child outcomes, whereas global measures of quality were never significant positive predictors, when both global and more specific measures of quality were included simultaneously in analyses. There is thus consistent evidence that more specific measures of quality are better predictors of child outcomes. With respect to dosage, several approaches were used in operationalizing both the cumulative and current dosage of children's exposure to ECE. Propensity score analyses that included baseline scores on outcomes to control for selection into larger dosages suggested that children with two as opposed to one year of Head Start had stronger vocabulary and literacy skills both immediately upon exit from Head Start and at the end of kindergarten. Fewer absences and more observed time spent on instruction were associated with stronger gains in literacy and mathematics skills. Finally, findings revealed that more time spent on instruction in classrooms with higher overall quality was particularly important to the development of mathematics skills. No other replicated evidence of quality by quantity interactions emerged.

III. TESTING FOR QUALITY THRESHOLDS AND FEATURES IN EARLY CARE AND EDUCATION.

In this chapter, we report on the analyses focusing on both quality thresholds and quality features. First, we address questions about quality thresholds, using two analytic approaches. The analyses ask whether there is evidence suggesting thresholds in the association between a specific quality measure and a specific child outcome. Second, we extend these analyses to ask whether each child outcome is more strongly related to global quality measures or to quality measures that measure teacher-child interactions or quality of instruction in a given content area. The research to date provides the basis for the articulation of two hypotheses related to quality thresholds and features: (1) the quality of ECE is a stronger predictor of residualized gains in child outcomes in classrooms with higher quality than in classrooms with lower quality and (2) more specific measures of quality are stronger predictors of residualized gains in child outcomes than are global measures. We turn now to analyses intended to address these hypotheses by using data from several data sets.

Head Start at ages 3 and 4 versus Head Start followed by state pre-k: Which is more effective?

As policy-makers contemplate expanding preschool opportunities for low-income children, one possibility is to fund two, rather than one year of Head Start for children at ages 3 and 4. Another option is to offer one year of Head Start followed by one year of pre-k. We ask which of these options is more effective. We use data from the Oklahoma pre-k study to examine these two 'pathways' into kindergarten using regression discontinuity to estimate the effects of each age-4 program, and propensity score weighting to address selection. We find that children attending Head Start at age 3 develop stronger pre-reading skills in a high quality pre-kindergarten at age 4 compared with attending Head Start at age 4. Pre-k and Head Start were not differentially linked to improvements in children's pre-writing skills or pre-math skills. This suggests that some impacts of early learning programs may be related to the sequencing of learning experiences to more academic programming.
