Leveraging an intensive time series of young children's movement to capture impulsive and inattentive behaviors in a preschool setting.

Studying within-person variability in children's behavior is frequently hindered by challenges collecting repeated observations. This study used wearable accelerometers to collect an intensive time series (2.7 million observations) of young children's movement at school (N = 62, Mage = 4.5 years, 54% male, 74% Non-Hispanic White) in 2021. Machine learning analyses indicated that children's typical forward acceleration was strongly correlated with lower teacher-reported inhibitory control and attention (r = -.69). Using forward movement intensity as a proxy for impulsivity, we partitioned the intensive time series and found that (1) children modulated their behavior across periods of the school day, (2) children's impulsivity increased across the school week, and (3) children with greater impulsivity showed greater variability in behavior across days.

Attention and behavior problems in childhood predict adult financial status, health, and criminal activity: A conceptual replication and extension of Moffitt et al. (2011) using cohorts from the United States and the United Kingdom.

This study is a conceptual replication of a widely cited study by Moffitt et al. (2011) which found that attention and behavior problems in childhood (a composite of impulsive hyperactive, inattentive, and impulsive-aggressive behaviors labeled "self-control") predicted adult financial status, health, and criminal activity. Using data from longitudinal cohort studies in the United States (n = 1,168) and the United Kingdom (n = 16,506), we largely reproduced their pattern of findings that attention and behavior problems measured across the course of childhood predicted a range of adult outcomes including educational attainment (ßU.S. = -0.22, ßU.K. = -0.13) and spending time in jail (ORU.S. = 1.74, ORU.K. = 1.48). We found that associations with outcomes in education, work, and finances diminished in the presence of additional covariates for children's home environment and achievement but associations for other outcomes were more robust. We also found that attention and behavior problems across distinct periods of childhood were associated with adult outcomes. Specific attention and behavior problems showed some differences in predicting outcomes in the U.S. cohort, with attention problems predicting lower educational attainment and hyperactivity/impulsivity predicting ever spending time in jail. Together with the findings from Moffitt et al., our study makes clear that childhood attention and behavior problems are associated with a range of outcomes in adulthood for cohorts born in the 1950s, 1970s, and 1990s across three countries.

Ambient Temperature Increases and Preschoolers' Outdoor Physical Activity.

This cross-sectional study evaluates the association of high outdoor temperatures with children's engagement in physical activity during play.

Physical punishment and child, adolescent, and adult outcomes in low- and middle-income countries: protocol for systematic review and meta-analysis.

BACKGROUND: Physical punishment at home and in schools is widespread around the world. Systematic reviews and meta-analyses have synthesized evidence, mostly from high-income countries (HICs), showing that physical punishment relates to multiple detrimental individual outcomes. Yet, less work has been done to synthesize the evidence on the association between physical punishment at home and schools and child, adolescent, and adult outcomes in low- and middle-income countries (LMICs), where more than 90% of children live and physical punishment is most socially normative and prevalent. In this manuscript, we present a protocol for a systematic review and meta-analysis on the characteristics of the research, associations, and variation in associations, between physical punishment at home and in schools and child, adolescent, and adult outcomes in LMICs. METHODS: We will conduct a review of studies published in peer-reviewed journals using quantitative methods to assess the association between physical punishment in childhood and/or adolescence and individual outcomes in LMICs. We will search for studies in 10 different databases using keywords in English, Spanish, Portuguese, Arabic, and Chinese related to physical punishment. We will extract qualitative data from the studies and the statistics needed to transform all study-level effect sizes into standardized mean difference effect sizes. For the analyses, we will employ multi-level meta-analyses to use multiple effect sizes per study and leverage within-study variation as well as between study variation using moderation analysis. Besides the meta-analyses, we will also conduct a narrative synthesis of the findings. DISCUSSION: The proposed systematic review and meta-analysis will provide timely evidence to inform global research, policy, and practice on the links between physical punishment and lifelong individual outcomes.

Preschoolers' executive functions following indoor and outdoor free play.

BACKGROUND: Children's executive functions develop rapidly during the preschool years and are critical for attending to lessons and meeting classroom expectations. Engaging in periods of outdoor play that have lower regulatory requirements and that provide opportunities for physical activity may help children maintain control over their behavior when they are back in settings with higher regulatory requirements. However, little work has formally examined this proposition in early childhood. METHODS: This study used a quasi-experimental design to examine preschoolers' executive functions following indoor compared to outdoor play. A total of 72 children (mean age = 4.5 years, 46% female, 73% non-Hispanic White) participated in task-based assessments of attention shifting and inhibitory control and in classroom observations of attention and inhibitory control. A subsample of the children (n = 51) was assessed for physical activity using accelerometry to examine the extent to which young children's physical activity during outdoor play predicted their subsequent executive functions better than their physical activity during indoor play. RESULTS: Children showed greater attention during classroom circle time following outdoor play compared to after indoor play (d = .34). Children's non-sedentary activity during indoor play was not related to their subsequent task-based executive functions but showed negative associations with their subsequent classroom-based executive functions. Children's percentage of time spent in non-sedentary physical activity during outdoor play showed a quadratic association with subsequent task-based inhibitory control but linear associations with subsequent classroom-based attention and inhibitory control during circle time. CONCLUSION: Periods of outdoor play that involve recommended amounts of physical activity may help young children engage executive functions when they return to the classroom.

Parent involvement and children's academic achievement: Evidence from a census of public school students in Brazil.

In order to broaden findings beyond high-income countries, this study used path models to test associations between parent involvement and student achievement in Brazil using a 2017 census of public school students in fifth grade (N = 2,167,729, Mage  = 11, 49 % female, 44% Parda, 29% White, 11% Black, 3% Asian, 3% Indigenous) and ninth grade (N = 1,782,899, Mage  = 15, 51% female, 46% Parda, 29% White, 12% Black, 4% Asian, 3% Indigenous). Parent involvement showed positive associations with student reading and math achievement for fifth graders (ßs = .11 & .09) but essentially null associations for ninth graders (ßs = -.01). Students' homework completion mediated associations in both grades (ßs = .03). Parent education was not a strong moderator of associations.

Total Play Time Needed for Preschoolers to Reach Recommended Amount of Non-Sedentary Activity.

Health guidelines suggest that caregivers provide preschoolers with opportunities to be physically active for 3 h per day (roughly 15 min per waking hour), but because children are not continuously active, it is unclear what amount of time is needed to reach this goal. This naturalistic study enrolled 67 children (M = 4.5 years, 46% female) who wore accelerometers to measure their activity during indoor and outdoor free -play (N = 315,061 s). An hour of indoor play was insufficient for most children to reach 15 min of physical activity. When outside, most children reached 15 min of physical activity after slightly more than 30 min. Children engaged in outdoor activity sporadically (1.7 starts/stops per minute). Most physical activity occurred in bouts shorter than 20 s. Indoor free-play does not, on its own, provide sufficient opportunity for preschoolers to engage in physical activity consistent with health guidelines. As a result, outdoor play for at least 30 min at a time has a key role in meeting these guidelines.

Amount and type of physical activity as predictors of growth in executive functions, attentional control, and social self-control across 4 years of elementary school.

This paper used a nationally representative sample of children from the United States to examine the extent to which physical activity and sports participation may promote growth in children's executive functions (EFs), attention, and social self-control over time. Using data from the ECLS-K:2011 (N = 18,174), findings indicated that regular physical activity predicted growth in EFs and attention from 3rd to 4th grade (ßs = 0.03-0.05) but not from kindergarten to 1st grade. After controlling for the frequency of physical activity, participation in group sports predicted increases in EFs, attention, and social self-control during both periods (ßs = 0.02-0.04). Though modest in size, the findings suggest that encouraging children to engage in more frequent and more team-based activity will benefit the development of their EFs and related skills, and especially so for children in middle childhood.

Measuring children's behavioral regulation in the preschool classroom: An objective, sensor-based approach.

Children's abilities to regulate their behaviors are critical for learning and development, yet researchers lack an objective, precise method for assessing children's behavioral regulation in their everyday environments such as their classrooms. This study tested a sensor-based approach to assess preschool children's behavioral regulation objectively, precisely, and naturalistically. Children wore accelerometer devices as they engaged in center-based play in their preschool classrooms for roughly 45 min (N = 50 children, 48% female, mean age = 4.5 years). Set to record data each second, these devices collected information about children's movement (N = 140,564 observations). From these data, the authors extracted concrete behaviors hypothesized to index behavioral regulation and compared them with teacher and observer ratings of the same. Initiating movement more frequently, staying seated in activities for shorter amounts of time, and spending a greater amount of time in motion were related to lower ratings of attention and inhibitory control by teachers and by observers of classroom group time, median r = .45, p < .01. These same objectively measured behaviors showed only weak associations with children's performance on assessments of cognitive regulation, median r = .11, p = .47. The findings indicate that ambulatory accelerometers can capture movement-based indicators of children's behavioral regulation in the classroom setting and that performance on measures of cognitive regulation does not strongly predict children's behavior in the classroom. As an unobtrusive and objective measure, actigraphy may become an important tool for studying children's behavioral regulation in everyday contexts.

Patterns of Childhood Body Mass Index Percentile Gains as Predictors of Adolescent Body Mass Index, Waist Circumference, and Blood Pressure.

OBJECTIVE: To examine whether patterns of body mass index (BMI) percentile gains across childhood predict BMI percentile, overweight and obesity, waist circumference, and elevated or prehypertensive blood pressure at age 15. METHODS: Trained technicians in the Study of Early Child Care and Youth Development assessed children's weight and height from birth to 15 years and waist circumference and blood pressure at age 15 (n = 1132). Children's BMI percentile trajectories from age 2 to age 13 along with 28 demographic and social covariates were used to predict BMI percentile, waist circumference, overweight, obesity, and elevated or prehypertensive blood pressure. Linear and logistic regressions were used to predict BMI percentile, overweight, obesity, waist circumference, and elevated or prehypertensive blood pressure. RESULTS: Children were classified into one"?>1 of 4four"?> BMI percentile trajectories: "low stable" (28.4%), "low-to-high" (11.8%), "median stable" (29.0%), and "high rising" (30.7%). Children in trajectory classes characterized by persistent above average BMI percentile or by periods of rapid BMI percentile gains were more likely than their peers to experience poor weight and elevated or prehypertensive outcomes in adolescence. Trajectory class membership explained substantially more variance in adolescent health outcomes than demographic covariates alone. Estimated maternal BMI was a key independent predictor of adolescent outcomes. CONCLUSIONS: Different patterns of BMI percentile gains, namely those with rapid gains or persistently above average BMI percentile, from ages 2 to 13 predicted weight, waist circumference, and elevated or prehypertensive blood pressure at age 15, above and beyond demographic and social characteristics.

It matters how you start: Early numeracy mastery predicts high school math course-taking and college attendance.

Using data from the Applied Problems subtest of the Woodcock-Johnson Tests of Achievement (Woodcock & Johnson, 1989/1990, Woodcock-Johnson psycho-educational battery-revised. Allen, TX: DLM Teaching Resources) administered to 1,364 children from the National Institute of Child Health and Human Development (NICHD) Study of Early Childcare and Youth Development (SECCYD), this study measures children's mastery of three numeric competencies (counting, concrete representational arithmetic and abstract arithmetic operations) at 54 months of age. We find that, even after controlling for key demographic characteristics, the numeric competency that children master prior to school entry relates to important educational transitions in secondary and post-secondary education. Those children who showed low numeric competency prior to school entry enrolled in lower math track classes in high school and were less likely to enrol in college. Important numeracy competency differences at age 54 months related to socioeconomic inequalities were also found. These findings suggest that important indicators of long-term schooling success (i.e., advanced math courses, college enrollment) are evident prior to schooling based on the levels of numeracy mastery.

Post-Pregnancy Factors Predicting Teen Mothers' Educational Attainment by Age 30 in Two National Cohorts.

Women who begin childbearing as teenagers attain lower levels of education than women who delay childbearing until age 20 and later. Little is known about post-pregnancy factors that predict educational attainment among teen mothers. The current study examined whether teen mothers' environment and experiences 2 years after their first birth contribute to their educational outcomes by age 30, net of selection factors associated with teenage childbearing. Data were from two cohorts, the National Longitudinal Surveys of Youth 1979 (N = 241) and 1997 (N = 378). Multinomial logistic regression modeling was used to assess associations of post-pregnancy factors with teen mothers' educational attainment. Having child care was associated with increased odds of attaining a high school diploma and of attending college in both cohorts. Providing regular and subsidized child care for teen mothers is an opportunity to support teen mothers in achieving higher levels of educational attainment.

Physical punishment and child outcomes: a narrative review of prospective studies.

Physical punishment is increasingly viewed as a form of violence that harms children. This narrative review summarises the findings of 69 prospective longitudinal studies to inform practitioners and policy makers about physical punishment's outcomes. Our review identified seven key themes. First, physical punishment consistently predicts increases in child behaviour problems over time. Second, physical punishment is not associated with positive outcomes over time. Third, physical punishment increases the risk of involvement with child protective services. Fourth, the only evidence of children eliciting physical punishment is for externalising behaviour. Fifth, physical punishment predicts worsening behaviour over time in quasi-experimental studies. Sixth, associations between physical punishment and detrimental child outcomes are robust across child and parent characteristics. Finally, there is some evidence of a dose-response relationship. The consistency of these findings indicates that physical punishment is harmful to children and that policy remedies are warranted.

Twin Differences in Harsh Parenting Predict Youth's Antisocial Behavior.

In the current study, we leveraged differences within twin pairs to examine whether harsh parenting is associated with children's antisocial behavior via environmental (vs. genetic) transmission. We examined two independent samples from the Michigan State University Twin Registry. Our primary sample contained 1,030 families (2,060 twin children; 49% female; 6-10 years old) oversampled for exposure to disadvantage. Our replication sample included 240 families (480 twin children; 50% female; 6-15 years old). Co-twin control analyses were conducted using a specification-curve framework, an exhaustive modeling approach in which all reasonable analytic specifications of the data are interrogated. Results revealed that, regardless of zygosity, the twin experiencing harsher parenting exhibited more antisocial behavior. These effects were robust across multiple operationalizations and informant reports of both harsh parenting and antisocial behavior with only a few exceptions. Results indicate that the association between harsh parenting and children's antisocial behavior is, to a large degree, environmental in origin.

Trust in expert versus lay comments in online articles about spanking and car seat safety.

In this study, we experimentally examined parents' perceptions of scientific information about spanking, a controversial topic, and car seat safety, a consensus topic, presented in online news articles. Specifically, we tested whether parents of children ages 2 to 8 years would trust scientific experts (speaking from professional expertise) more than online lay commenters (speaking from personal experience). One hundred and eighty parents across 41 U.S. states were recruited online from Amazon's Mechanical Turk (124 mothers, 56 fathers; 74% White, 9% Black, 8% Latino, 8% Asian, and 1% other or multiple ethnicities). Parents were randomly assigned to read a news article with an expert discussing spanking research that varied by two conditions: The news article contained either anti-spanking lay comments or pro-spanking lay comments. All parents also read a second news article on car seat safety (a consensus topic). Between-condition analyses were used to compare perceptions of the comment conditions, and within-condition analyses were used to compare perceptions of the expert knowledge versus the comments and to compare perceptions of the spanking expert versus the car seat expert. Moderation analyses were used to compare parents' perceptions based on their attitudes toward spanking. Parents with positive attitudes toward spanking recognized pro-spanking comments as opinion, yet still found them more trustworthy than a scientist taking the opposite position. All parents perceived the car seat expert as trustworthy. The results highlight challenges in disseminating information about controversial topics to the public.

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.

Foster Care: How We Can, and Should, Do More for Maltreated Children.

Foster care provides round-the-clock substitute care for nearly 700,000 U.S. children who are temporarily or permanently separated from their family of origin each year. Each state manages its own foster care system according to federal regulations. Despite numerous large-scale federal policy reforms over the past several decades, substantial concerns remain about the experiences and outcomes of children in the foster care system. The most recent effort to reform foster care, the Family First Prevention Services Act of 2018, attempts to both reduce the use of foster care and increase the quality of care. In this report, we review how policy has shaped the experiences and outcomes of children in foster care, where policy has succeeded, and where it falls short of achieving its goals. We then identify opportunities for federal and state policy to better support the safety, health, and well-being of children in foster care.

There is still no evidence that physical punishment is effective or beneficial: Reply to Larzelere, Gunnoe, Ferguson, and Roberts (2019) and Rohner and Melendez-Rhodes (2019).

The authors' original article (Gershoff et al., 2018) summarized the extensive body of research demonstrating that parents' use of physical punishment is ineffective and linked with risk of detrimental outcomes for children. In this Reply, the authors agree with several points raised in two commentaries on the article (Larzelere, Gunnoe, Ferguson, & Roberts, 2019; Rohner & Melendez-Rhodes, 2019)-that statistical rigor is needed before making conclusions and that potential contextual moderators need to be considered. However, neither commentary negated the scientific inferences and conclusions of the Gershoff et al. article or presented any convincing evidence that physical punishment is beneficial to children. The preponderance of evidence clearly indicates physical punishment is harmful, a finding that is increasingly being recognized by professional organizations, including the American Psychological Association.

Age-specific risk factors associated with placement instability among foster children.

Placement instability places foster children at an increased risk of negative developmental outcomes. Previous research has yielded inconsistent results on risk factors for placement instability. Therefore, we investigated two research questions: (1) Which child attributes and case histories are associated with placement disruptions (moves indicative of child, agency or caregiver dissatisfaction with the existing placement)?; and (2) How do associations of child attributes and case histories with placement disruptions vary by developmental stage --early childhood (0-5 years), middle childhood (6-12 years), and adolescence (13 years or older)? Using a complete entry cohort of 23,765 foster children in Texas, our results demonstrated that the effects of different risk factors varied by placement end reason and across developmental stages. Of note, kinship placement, compared to non-relative foster care, and placement with all siblings were each associated with an increased risk of substandard care disruptions. Placements with females or Hispanic children were at an increased risk of child-initiated disruption, whereas placements with Black children were more likely to end due to placement mismatch or substandard care reasons. Finally, the adolescence age group was always associated with the greatest increase in risk regardless of disruption reason. These findings provide researchers, caseworkers, and policymakers important information on the risk factors for placement instability among children in foster care.

The strength of the causal evidence against physical punishment of children and its implications for parents, psychologists, and policymakers.

The question of whether physical punishment is helpful or harmful to the development of children has been subject to hundreds of research studies over the past several decades. Yet whether causal conclusions can be drawn from this largely nonexperimental research and whether the conclusions generalize across contexts are issues that remain unresolved. In this article, the authors summarize the extent to which the empirical research on physical punishment meets accepted criteria for causal inference. They then review research demonstrating that physical punishment is linked with the same harms to children as is physical abuse and summarize the extant research that finds links between physical punishment and detrimental outcomes for children are consistent across cultural, family, and neighborhood contexts. The strength and consistency of the links between physical punishment and detrimental child outcomes lead the authors to recommend that parents should avoid physical punishment, psychologists should advise and advocate against it, and policymakers should develop means of educating the public about the harms of and alternatives to physical punishment.
