The predictive validity of the strange situation procedure: Evidence from registered analyses of two landmark longitudinal studies.

Meta-analyses demonstrate that the quality of early attachment is modestly associated with peer social competence (r = .19) and externalizing behavior (r = -.15), but weakly associated with internalizing symptoms (r = -.07) across early development (Groh et al., Child Development Perspectives, 11(1), 70-76, 2017). Nonetheless, these reviews suffer from limitations that undermine confidence in reported estimates, including evidence for publication bias and the lack of comprehensive assessments of outcome measures from longitudinal studies in the literature. Moreover, theoretical claims regarding the specificity of the predictive significance of early attachment variation for socioemotional versus academic outcomes had not been evaluated when the analyses for this report were registered (but see Dagan et al., Child Development, 1-20, 2023; Deneault et al., Developmental Review, 70, 101093, 2023). To address these limitations, we conducted a set of registered analyses to evaluate the predictive validity of infant attachment in two landmark studies of the Strange Situation: the Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) and the NICHD Study of Early Child Care and Youth Development (SECCYD). Across-time composite assessments reflecting teacher report, mother report, and self-reports of each outcome measure were created. Bivariate associations between infant attachment security and socioemotional outcomes in the MLSRA were comparable to, or slightly weaker than, those reported in the recent meta-analyses, whereas those in the SECCYD were weaker for these outcomes. Controlling for four demographic covariates, partial correlation coefficients between infant attachment and all socioemotional outcomes were r ≤ .10 to .15 in both samples. Compositing Strange Situations at ages 12 and 18 months did not substantively alter the predictive validity of the measure in the MLSRA, though a composite measure of three different early attachment measures in the SECCYD did increase predictive validity coefficients. Associations between infant attachment security and academic skills were unexpectedly comparable to (SECCYD) or larger than (MLSRA) those observed with respect to socioemotional outcomes.

Early cumulative risk and outcomes in adolescence and adulthood: The role of executive function and behavioral regulation.

This study examined the extent to which early cumulative risk predicts a range of behavioral and psychological outcomes (i.e., depression, future orientation, risky behavior, educational attainment, and socioeconomic outcomes) measured at ages 15 and 26 and whether executive function (EF) and/or behavioral regulation mediated and/or moderated these associations. Data for this study came from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development and included a sample of 1,364 participants (52% male) born in 1991 and followed through age 26. Results indicated that early cumulative risk was related to depression and risky behavior at age 15 as well as depression, income, future orientation, and educational attainment at age 26. Furthermore, both EF and behavioral regulation mediated relations among cumulative risk and academic achievement at age 15 and between cumulative risk and income and educational attainment at age 26. Finally, three significant interactions emerged for age 15 outcomes, indicating that EF and behavioral regulation may change relations between cumulative risk and depression, reading, and future orientation. Implications for future research are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

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).

Quality of early childcare and education predicts high school STEM achievement for students from low-income backgrounds.

High-quality early childcare and education (ECE) has demonstrated long-term associations with positive educational and life outcomes and can be particularly impactful for children from low-income backgrounds. This study extends the literature on the long-term associations between high-quality caregiver sensitivity and responsiveness and cognitive stimulation (i.e., caregiving quality) in ECE settings and success in science, technology, engineering, and mathematics (STEM) in high school. Using the 1991 National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n = 1,096; 48.6% female; 76.4% White, 11.3% African American, 5.8% Latine, 6.5% other), results demonstrated that caregiving quality in ECE was associated with reduced disparities between low- and higher-income children's STEM achievement and school performance at age 15. Disparities in STEM school performance (i.e., enrollment in advanced STEM courses and STEM grade point average) and STEM achievement (i.e., Woodcock-Johnson cognitive battery) were reduced when children from lower-income families experienced more exposure to higher caregiving quality in ECE. Further, results suggested an indirect pathway for these associations from caregiving quality in ECE to age 15 STEM success through increased STEM achievement in Grades 3 through 5 (ages 8-11 years). Findings suggest that community-based ECE is linked to meaningful improvements in STEM achievement in Grades 3 through 5 which in turn relates to STEM achievement and school performance in high school, and caregiving quality in ECE is particularly important for children from lower-income backgrounds. This work has implications for policy and practice positioning caregivers' cognitive stimulation and sensitivity in ECE settings across the first 5 years of life as a promising lever for bolstering the STEM pipeline for children from lower-income backgrounds.

Participation and enjoyment in Out-of-School activities during adolescence as predictors of activities in adulthood.

This study examined associations between adolescents' participation in out-of-school activities and their participation in activities at age 26 (N = 1041, 50% girls, 77% White). More frequent adolescent participation in sports, arts, volunteer/community service, and religious activities increased the odds of participating in the same type of activity at age 26. Adolescents' enjoyment of activities partially explained the developmental continuity in activity participation. There was limited evidence that individuals' participation across different types of activities was associated. Finally, the diversity or breadth of adolescents' activity participation was associated with larger activity breadth at age 26. These findings suggest that adolescents' out-of-school activities help set the stage for participating in similar, but not different activities during young adulthood.

Longitudinal associations between adolescent out-of-school time and adult substance use.

INTRODUCTION: Based on Bronfenbrenner's bioecological theory and Bornstein's specificity principle, the purpose of this study was to examine adolescents' time in out-of-school settings as a precursor of three types of problematic substance use in adulthood (i.e., binge drinking, regular marijuana use, and use of illicit drugs). METHOD: Adolescents (N = 978) reported the time they spent in four common out-of-school settings at ages 15 and 18: unsupervised time with peers, organized sports, other organized activities, and paid employment. At age 26, participants reported binge drinking, marijuana use, and illicit drug use. RESULTS AND CONCLUSIONS: Adolescents' time in out-of-school settings during high school predicted age 26 substance use over and above family and adolescent factors, including adolescents' substance use during high school. Adolescents' unsupervised time with peers increased the odds and frequency of binge drinking and regular marijuana use at age 26. Time in high school organized sports increased the odds of binge drinking at age 26, but not marijuana or illicit drug use. Time spent in other organized activities, such as community service and the arts, lowered the odds of illicit drug use whereas paid employment in high school was not related to age 26 substance use. Aligned with Bornstein's specificity principle, time spent in specific out-of-school settings during adolescence were differentially related to substance use problems in early adulthood, with some activities serving as a risk factor and other activities serving as a protective factor for young adults.

Child care and family processes: Bi-directional relations between child care quality, home environments, and maternal depression.

The current study examined whether within-family changes in child care quality and quantity predicted subsequent changes in home environment quality and maternal depression across early childhood (6 to 54 months of age). Data were drawn from the NICHD Study of Early Child Care and Youth Development (n = 1239; 77% White; 48% female; data collection from 1991 to 1996), and were analyzed using Random Intercept Cross-Lagged Panel Models. Within-family increases in child care quality predicted modest increases in home environment quality (ß = .13-.17). These effects were most robust from child age 6 to 15 months. Increases in child care quality produced small, statistically non-significant, reductions in depression. Time-specific increases in child care quantity were not consistently predictive of either outcome.

Tracing the origins of the STEM gender gap: The contribution of childhood spatial skills.

Despite some gains, women continue to be underrepresented in many science, technology, engineering, and math (STEM) fields. Using a national longitudinal dataset of 690 participants born in 1991, we tested whether spatial skills, measured in middle childhood, would help explain this gender gap. We modeled the relation between 4th-grade spatial skills and STEM majors while simultaneously accounting for competing cognitive and motivational mechanisms. Strong spatial skills in 4th grade directly increased the likelihood of choosing STEM college majors, above and beyond math achievement and motivation, verbal achievement and motivation, and family background. Additionally, 4th-grade spatial skills indirectly predicted STEM major choice via math achievement and motivation in the intervening years. Further, our findings suggest that gender differences in 4th-grade spatial skills contribute to women's underrepresentation in STEM majors. RESEARCH HIGHLIGHTS: Using a national longitudinal dataset, we found 4th-grade spatial skills directly predicted STEM college major choice after accounting for multiple cognitive and motivational mechanisms. Strong spatial skills in 4th grade also elevated STEM major choice via enhanced math achievement and motivation in the intervening years. Gender differences in 4th-grade spatial skills contributed to women's underrepresentation in STEM college majors.

Self-control and cooperation in childhood as antecedents of less moral disengagement in adolescence.

Moral disengagement is a social cognition people use to engage in wrongdoings even when they know it is wrong. However, little is known about the antecedents that predict moral disengagement. The current study focuses on the development of self-control and cooperation during middle childhood as two antecedents of moral disengagement among 1,103 children (50% female; 77% White, 12% Black, 6% Hispanic, and 5% other). Children's self-control at age 8 and growth in self-control from age 8 to 11 were positively linked to adolescents seeing themselves as having self-control at age 15, which then predicted less moral disengagement at age 18. Children's cooperation at age 8 also was positively linked to adolescents' self-views of cooperation at age 15, which in turn, was associated with less moral disengagement at age 18. These findings demonstrate the potential of self-control and cooperation as intrapersonal and interpersonal strengths during middle childhood for mitigating moral disengagement 10 years later.

Early maternal sensitivity and markers of physical health: Enduring or transient associations from childhood to adulthood?

Individual differences in the quality of early experiences with primary caregivers have been reliably implicated in the development of socioemotional adjustment and, more recently, physical health. However, few studies have examined the development of such associations with physical health into the adult years. To that end, the current study used prospective, longitudinal data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,306, 52% male, 77% White/non-Hispanic) to investigate whether associations between direct observations of maternal sensitivity in the first 3 years of life and repeated assessments of two commonly used, objective indicators of physical health (i.e., body mass and mean arterial blood pressure) remained stable or diminished in magnitude over time. Associations between early maternal sensitivity and lower body mass remained relatively stable from age 54 months to 26 years and were robust to the modeling of autoregressive and second-order stability processes as well as the inclusion of potential demographic confounders. In contrast, although associations between early caregiving and lower mean arterial pressure remained relatively stable from Grade 4 to age 15 years (the oldest age for which mean arterial pressure was assessed thus far), these associations were not robust to the inclusion of covariates and the modeling of second-order stability processes.

Adult outcomes of sustained high-quality early child care and education: Do they vary by family income?

Experimental research demonstrates sustained high-quality early care and education (ECE) can mitigate the consequences of poverty into adulthood. However, the long-term effects of community-based ECE are less known. Using the 1991 NICHD Study of Early Child Care and Youth Development (n = 994; 49.7% female; 73.6% White, 10.6% African American, 5.6% Latino, 10.2% Other), results show that ECE was associated with reduced disparities between low- and higher-income children's educational attainment and wages at age 26. Disparities in college graduation were reduced the more months that low-income children spent in ECE (d = .19). For wages, disparities were reduced when children from low-income families attended sustained high-quality ECE (d = .19). Findings suggest that community-based ECE is linked to meaningful educational and life outcomes, and sustained high-quality ECE is particularly important for children from lower-income backgrounds.

Preschool executive function and adult outcomes: A developmental cascade model.

The present study examined longitudinal associations between preschoolers' executive function (EF) and adult educational attainment, impulse control, and general health directly and through its cascading effects on childhood and adolescent EF using a large, national, and prospective longitudinal sample of participants. Data were drawn from the National Institute of Child Health and Human Development study of Early Child Care and Youth Development (NICHD SECCYD) and included a diverse sample (52% male at birth; 76% White; 13% Black; 6% Hispanic; and 5% other; 14.23 mean years of maternal education) of 1,364 participants born in 1991 and followed through age 26. Four main findings emerged. First, we observed significant bivariate relations between EF measured at 54 months and adult educational attainment (r = .36, p < .01), and impulse control (r = .11, p = .01). Second, early EF measured during preschool and childhood explained variance in adult educational attainment and impulse control above and beyond adolescent EF. Third, childhood EF mediated the association between preschool EF and adult educational attainment and impulse control but did not operate through adolescent EF. Finally, neither preschool EF nor EF measured at other developmental stages predicted health during adulthood. Together, these findings shed light on the direct and cascading influences of EF across development on important domains of adult functioning.

Developmental pathways linking the quality and intensity of organized afterschool activities in middle school to academic performance in high school.

INTRODUCTION: Adolescents' organized afterschool activities have been linked to their academic performance, but processes contributing to these relations are not well understood. This study tested two pathways linking activity intensity and activity quality in 6th grade to high school academic performance: adolescents' activities in 9th grade and adolescents' academic skills in 9th grade. METHODS: Data were from the Study of Early Child Care and Youth Development, a longitudinal study conducted at 10 sites in the United States. Data were collected from 918 participants (51% female) who were assessed in 6th grade (Age 12; middle school), 9th grade (Age 15; beginning of high school), and 12th grade (Age 18; end of high school). RESULTS & CONCLUSIONS: Findings from structural equation models indicated that adolescents who had higher activity intensity and activity quality in 6th grade participated in activities with higher intensity and quality in 9th grade. These 9th grade activities formed an indirect path linking 6th grade activities to high school academic performance, including grades and number of advanced classes. In addition, 6th grade activity quality promoted adolescents' work orientations in 9th grade, a key academic disposition that then predicted grades and number of advanced classes in high school. These findings suggest that organized afterschool activities in middle school may prepare adolescents for academic success in high school via their participation in activities in 9th grade as well a stronger work orientation in 9th grade.

Convergent and Discriminant Validity of Retrospective Assessments of the Quality of Childhood Parenting: Prospective Evidence From Infancy to Age 26 Years.

Retrospective self-report assessments of adults' childhood experiences with their parents are widely employed in psychological science, but such assessments are rarely validated against actual parenting experiences measured during childhood. Here, we leveraged prospectively acquired data characterizing mother-child and father-child relationship quality using observations, parent reports, and child reports covering infancy through adolescence. At age 26 years, approximately 800 participants completed a retrospective measure of maternal and paternal emotional availability during childhood. Retrospective reports of childhood emotional availability demonstrated weak convergence with composites reflecting prospectively acquired observations (R2s = .01-.05) and parent reports (R2s = .02-.05) of parenting quality. Retrospective parental availability was more strongly associated with prospective assessments of child-reported parenting quality (R2s = .24-.25). However, potential sources of bias (i.e., depressive symptoms and family closeness and cohesiveness at age 26 years) accounted for more variance in retrospective reports (39%-40%) than did prospective measures (26%), suggesting caution when using retrospective reports of childhood caregiving quality as a proxy for prospective data.

The development of cooperation and self-control in middle childhood: Associations with earlier maternal and paternal parenting.

Developmental theories and previous research have emphasized the significance of cooperation and self-control in middle childhood. The present study extends previous research by examining (a) the growth of cooperation and self-control as well as the relations between them in middle childhood (third to sixth grade) and (b) the extent to which mothers' and fathers' parenting during early childhood (54 months and first grade) was associated with children's cooperation and self-control. The sample included 705 children (51% female, 86% White) and their mothers, fathers, and teachers in the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD). Children, on average, exhibited increases in self-control but not cooperation from third to sixth grade though the increases were smaller for children who had higher self-control or cooperation at third grade. Children who exhibited higher self-control at third grade tended to exhibit higher cooperation at third grade; similar positive associations emerged for the changes in self-control and cooperation over time. In addition, if a child exhibited higher self-control at one time point relative to their typical average level, they tended to also exhibit higher cooperation at the same time point relative to their typical average level. However, these relative deviations within person were not associated over time. Lastly, maternal and paternal sensitive and stimulating parenting in early childhood was positively associated with children's cooperation and self-control in middle childhood. Overall, our findings shed light on the growth of and the relations between cooperation and self-control in middle childhood and highlight the role of maternal and paternal parenting in early childhood.

Predictors and consequences of school mobility in middle childhood.

In this prospective longitudinal study (N = 1094, M age = 5.6 years to M age = 11.1 years), we examined family factors associated with school mobility and then asked if either a move during the previous year or cumulative moves across elementary school were related to child functioning. Family factors were not linked to a recent move or a single move, but changes in family income and household structure did predict higher odds of two or more moves in elementary school. There was no evidence that a recent move or a single move was related to children's academic or social functioning. Effects of two or more moves on child functioning were not significant after controlling for the number of analyses that were conducted. Taken together, school mobility during elementary school did not appear to be a pervasive risk although we were unable to study very high rates of school mobility because of very small sample sizes.

Children's developing work habits from middle childhood to early adolescence: Cascading effects for academic outcomes in adolescence and adulthood.

Children's work habits at school include being a hard worker, turning in work on time, following classroom rules, and putting forward one's best effort. Models on youth character, noncognitive skills, and social-emotional learning suggest that self-management skills like work habits are critical for individuals' subsequent academic success. Using data from 1,124 children in the NICHD Study of Early Childcare and Youth Development (49% female; 77% White), we examined children's developing work habits from first to sixth grade and their developmental cascading effects on academic outcomes at the beginning and end of high school as well as at age 26. The findings on differential stability of work habits (i.e., bivariate correlations) suggest that children were likely to maintain their relative position among peers from first to sixth grade. The complementary findings on mean-level changes from the latent growth curves suggest that children's work habits exhibited mean-level increases over the same period, meaning that children's work habits became more advanced from first to sixth grade. Models used to examine the developmental cascades of work habits suggest that children's work habits at first grade and the growth in children's work habits from first to sixth grade (a) directly predicted their academic outcomes at the beginning and the end of high school, and (b) indirectly predicted their educational attainment at age 26 through their academic outcomes during adolescence. These findings underscore the importance of foundational noncognitive skills during middle childhood that predict individuals' academic outcomes up to 20 years later in adulthood.

Observing individual children in early childhood classrooms using Optimizing Learning Opportunities for Students (OLOS): A feasibility study.

In this study, we present a newly developed observational system, Optimizing Learning Opportunities for Students (OLOS). OLOS is designed to elucidate the learning opportunities afforded to individual children within early childhood classrooms and as they transition to formal schooling (kindergarten through third grade). OLOS records the time spent in different types of learning opportunities (e.g., play, literacy, math) and the frequency of specific discourse moves children and teachers use (child talk and teacher talk). Importantly, it is being designed to be used validly and reliably by practitioners. Using OLOS, we explored individual children's experiences (n = 68 children in 12 classrooms) in four different types of early childhood programs; state-funded, state-funded PK serving children with disabilities, Head Start, and a tuition-based (non-profit) preschool. Results of our feasibility study revealed that we could feasibly and reliably use OLOS in these very different kinds of pre-kindergarten programs with some changes. OLOS provided data that aligned with our hypotheses and that our practitioner partners found useful. In analysing the observations, we found that individual children's learning opportunities varied significantly both within and between classrooms. In general, we observed that most of the PK day (or half day) was spent in language and literacy activities and non-instructional activities (e.g., transitions). Very little time in math and science was observed yet children were generally more likely to actively participate (i.e., more child talk) during academic learning opportunities (literacy, math, and science). The frequency of teacher talk also varied widely between classrooms and across programs. Plus, the more teacher talk we observed, the more likely we were to observe child talk. Our long-term aim is that OLOS can inform policy and provide information that supports practitioners in meeting the learning and social-behavioral needs of the children they serve.

Parenting, temperament, and attachment security as antecedents of political orientation: Longitudinal evidence from early childhood to age 26.

This article examines early childhood antecedents of adults' political orientation. Using longitudinal data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, we investigate associations between parenting beliefs and behaviors, child temperament, and attachment security during early childhood in relation to adult political ideology and party affiliation at age 26 years (N = 1,364). Young children's fearful temperament and anxious attachment security, as well as mothers' authoritarian parenting beliefs in early childhood, predicted conservative political orientations at age 26. Children's abilities to focus attention and avoidant attachment security predicted liberal orientations. These findings provide evidence that multiple aspects of early developmental experience-temperament, parenting, and infant-mother attachment-are associated with later political orientations.

Additive and synergistic relations of early mother-child and caregiver-child interactions for predicting later achievement.

This study examines associations between stimulating-responsive social interactions with mothers and nonparental childcare providers during the first 3 years of life and children's vocabulary and mathematics skills through age 15 (N = 1,364). Additive relations were found in which more stimulating-responsive interactions with mothers and with caregivers were linked to higher mathematics achievement in childhood and adolescence. More stimulating-responsive early interactions with mothers were also associated with larger child vocabularies through age 15. Synergistic relations, consistent with the dual-risk hypothesis, also were found. Children whose early interactions with both mothers and caregivers were low in stimulation and responsivity had substantially lower mathematics skills. Implications for early childhood interventions and policies are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
