Relating Kindergarten Attention to Subsequent Developmental Pathways of Classroom Engagement in Elementary School

The Joint Operations of Teacher-Student and Peer Relationships on Classroom Engagement among Low-Achieving Elementary Students: A Longitudinal Multilevel Study

Although both teacher-student relationship (TSR) and peer relationship (PR) have been found important for the development of students' classroom engagement, little research has been done regarding the joint operations of these two factors. Guided by a developmental systems framework, this study examined longitudinal between-person and within-person associations between TSR/ PR and classroom engagement in a sample of 784 low-achieving students in the first three years of elementary school. A multidimensional approach was used to distinguish positive and negative dimensions of TSR, as well as peer liking and disliking. At the between-person level, results showed that students' classroom engagement was positively predicted by positive TSR and PR liking and was negatively predicted by negative TSR and PR disliking. Both positive and negative TSR interacted with PR disliking at the between-person level, such that the associations between positive/negative TSR and classroom engagement were stronger for students with lower levels of PR disliking. At the within-person level, changes in classroom engagement were associated with contemporaneous year-to-year changes in positive/negative TSR and PR disliking. No within-person level interaction effects were found. Cross-level interaction showed that the effects of within-person negative TSR on classroom engagement were stronger for students with lower overall levels of PR disliking. Findings highlighted the importance of using a multilevel multidimensional approach to understand the joint operations of TSR and PR in the development of classroom engagement in low-achieving students in early elementary school.

Transactional associations between vocabulary and disruptive behaviors during the transition to formal schooling

This study investigated the transactional relations between vocabulary and disruptive behaviors (DB; physical aggression and opposition/rule breaking/theft and vandalism), during the transition to formal schooling, using a community sample of 572 children. Cross-lagged panel model analyses were used to examine bidirectional relationships, comparing physical aggression to non-aggressive DB. Transactional associations between vocabulary and DB were observed, coinciding with school entry. Lower vocabulary in preschool (60mo.) was predictive of higher physical aggression scores in kindergarten. In turn, higher physical aggression in kindergarten was predictive of lower vocabulary in 1st grade. For non-aggressive DB, recurrent associations were found. Lower verbal skills in preschool (42mo.) and kindergarten predicted higher non-aggressive DB scores later in preschool and in 1st grade respectively. In turn, higher non-aggressive DB in kindergarten predicted lower vocabulary scores in 1st grade. In contrast to transactional paths from vocabulary to DB, transactional paths from DB to vocabulary observed after the transition to elementary school remained significant after controlling for comorbid hyperactivity, impulsivity and inattention behaviors, suggesting these links were specific to aggressive and non-aggressive DB. Practical implications for prevention are discussed.

Longitudinal relations between self-regulatory skills and mathematics achievement in early elementary school children from Chinese American immigrant families

Drawing from two waves (∼1.5-2.5 years apart) of longitudinal data, the current study investigated the bidirectional associations between self-regulatory skills and mathematics achievement among a socioeconomically diverse sample of school-age Chinese American children from immigrant families (N = 258; 48.1% girls; ages 5.8-9.1 years; first to third grades at Wave 1). Children's self-regulatory skills were assessed with task-based measures of attention focusing, inhibitory control, behavioral persistence, and comprehensive executive function as well as parent- and teacher-reported effortful control. Multiple regressions showed that behavioral persistence and parent-reported effortful control positively predicted math achievement over time. Math achievement positively predicted comprehensive executive function over time. These effects were found when controlling for child age, sex, generation status, family socioeconomic status, parents' cultural orientations, and prior levels of math achievement or self-regulation. The prospective relation of math achievement predicting comprehensive executive function remained significant after a false discovery rate correction.

Prospective Associations Between Preschool Exposure to Violent Televiewing and Psychosocial and Academic Risks in Early Adolescent Boys and Girls

OBJECTIVE

Risks of early exposure to media violence remain unclear. This study examines typical early childhood violent media exposure and subsequent psychosocial and academic risks.

METHODS

Our longitudinal birth cohort comprised 978 girls and 998 boys. Child-reported and teacher-reported measures of adjustment at age 12 years were linearly regressed on parent-reported televised violence exposure at ages 3.5 and 4.5 years while adjusting for individual/family confounders.

RESULTS

For girls, preschool violent televiewing was associated with increases in emotional distress (b = 0.31; 95% confidence interval [CI], 0.13-0.49) and decreases in classroom engagement (b = -0.97; 95% CI, -1.55 to -0.40), academic achievement (b = -2.60; 95% CI, -3.48 to -1.72), and academic motivation (b = -0.58; 95% CI, -1.09 to -0.07) at age 12 years. For boys, preschool violent televiewing was associated with increases in emotionally distressed (b = 0.33; 95% CI, 0.13-0.53), inattentive (b = 0.25; 95% CI, 0.06-0.45), conduct disordered (b = 0.11; 95% CI, 0.00-0.21), and socially withdrawn behavior (b = 0.23; 95% CI, 0.05-0.40), as well as decreases in classroom engagement (b = -0.84; 95% CI, -1.57 to -0.12), academic achievement (b = -1.19; 95% CI, -2.15 to -0.23), and academic motivation (b = -0.58; 95% CI, -1.13 to -0.03) at age 12 years.

CONCLUSION

Compared with no preschool exposure, violent televiewing is associated with distinct and enduring psychosocial risks by early adolescence. Acknowledging such risks remains a pertinent health literacy target for pediatric professionals, parents, and communities.

Longitudinal relations between behavioral engagement and academic achievement: The moderating roles of socio-economic status and early achievement

This study investigated developmental trajectories of observationally coded engagement across the early elementary years and whether these trajectories were associated with children's academic achievement. Furthermore, we evaluated if these relations varied as a function of children's family socio-economic status and early reading and math skills. Data were collected from 301 children who were studied from kindergarten (Mage = 65.74 months; 49% boys) to 2nd grade. Children's behavioral engagement was observed in kindergarten, 1st, and 2nd grade. Reading and math skills were assessed via standardized tests in kindergarten and 2nd grade. Growth mixture models identified two classes of behavioral engagement: most children (87.0%) displayed relatively high behavioral engagement in the fall of kindergarten and decreased significantly across time (referred to below as high-decreasing class), and other children (13.0%) exhibited moderate behavioral engagement in the fall of kindergarten that was stable across time (referred to below as moderate-stable class). After controlling for academic skills in kindergarten and demographic variables (i.e., child age, sex, ethnicity, and family socio-economic status), children in the high-decreasing class displayed higher reading skills, but not math skills, than children in the moderate-stable class. Additional analyses revealed that differences in reading skills between the two classes were present only for children from low socio-economic status families or for children low in kindergarten reading skills. The findings suggest that economically or academically at-risk students might benefit more than their peers from high behavioral engagement.

Biophysiological stress markers relate differently to grit and school engagement among lower- and higher-track secondary school students

BACKGROUND

This study examines the relationship between adolescents' biophysiological stress (i.e. cortisol, alpha-amylase and oxidative stress) and the development of grit and school engagement over one school year.

AIMS

The study aims to identify how objective stress affects grit and three dimensions of school engagement. Based on the conservation of resources (COR) theory, the study considers lower- and higher-track school students and their genders.

SAMPLE

The sample consists of secondary school students (N = 82; M_Age  = 13.71; SD = 0.67; 48% girls) from Germany.

METHODS

Students participated in a questionnaire and a biophysiological study in the first semester (t1) of the school year and completed the same questionnaire at the end of the school year (t2). After conducting whole-sample analysis, a multi-group cross-lagged panel model was calculated to identify differences among students at lower- and higher-track schools.

RESULTS

Whole-sample analysis reveals that students who exhibit high levels of cortisol report lower cognitive school engagement at t2, whereas students who exhibit high levels of alpha-amylase exhibit less grit at t2. Additionally, lower-track students who exhibited high cortisol levels reported lower cognitive and emotional school engagement throughout the school year. Furthermore, higher-track students with high oxidative stress levels reported lower grit and behavioural school engagement at t2.

CONCLUSIONS

Examining the relationship between biophysiological stress markers and grit and school engagement of students at lower- and higher-track schools indicates that the educational context and its specific subculture shapes physiological stress reactions, which are related differently to grit and engagement dimensions.

Associations between measures of physical fitness and cognitive performance in preschool children

BACKGROUND

Given that recent studies report negative secular declines in physical fitness, associations between fitness and cognition in childhood are strongly discussed. The preschool age is characterized by high neuroplasticity which effects motor skill learning, physical fitness, and cognitive development. The aim of this study was to assess the relation of physical fitness and attention (including its individual dimensions (quantitative, qualitative)) as one domain of cognitive performance in preschool children. We hypothesized that fitness components which need precise coordination compared to simple fitness components are stronger related to attention.

METHODS

Physical fitness components like static balance (i.e., single-leg stance), muscle strength (i.e., handgrip strength), muscle power (i.e., standing long jump), and coordination (i.e., hopping on one leg) were assessed in 61 healthy children (mean age 4.5 ± 0.6 years; girls n = 30). Attention was measured with the "Konzentrations-Handlungsverfahren für Vorschulkinder" [concentration-action procedure for preschoolers]). Analyses were adjusted for age, body height, and body mass.

RESULTS

Results from single linear regression analysis revealed a significant (p < 0.05) association between physical fitness (composite score) and attention (composite score) (standardized ß = 0.40), showing a small to medium effect (F² = 0.14). Further, coordination had a significant relation with the composite score and the quantitative dimension of attention (standardized ß = 0.35; p < 0.01; standardized ß =  - 0.33; p < 0.05). Coordination explained about 11% (composite score) and 9% (quantitative dimension) of the variance in the stepwise multiple regression model.

CONCLUSION

The results indicate that performance in physical fitness, particularly coordination, is related to attention in preschool children. Thus, high performance in complex fitness components (i.e., hopping on one leg) tends to predict attention in preschool children. Further longitudinal studies should focus on the effectiveness of physical activity programs implementing coordination and complex exercises at preschool age to examine cause-effect relationships between physical fitness and attention precisely.

Is more child-initiated always better? Exploring relations between child-initiated instruction and preschoolers' school readiness

Although research suggests that the use of child-initiated vs. teacher-directed instructional practices in early childhood education has implications for learning and development, the precise nature of these effects remains unclear. Using data from the Midwest Child-Parent Center (CPC) Expansion Project, the present study examined the possibility that a blend of child- and teacher-directed practices best promotes school readiness among preschoolers experiencing high levels of sociodemographic risk and explored whether the optimal blend varies based on child characteristics. Sixty-two CPC preschool teachers reported their instructional practices throughout the year, using a newly developed questionnaire - the Classroom Activity Report (CAR). The average reported proportion of child-initiated instruction was examined in relation to students' end-of-year performance on a routine school readiness assessment (N = 1,289). Although there was no main effect of child-initiated instruction on school readiness, there was a significant interaction between instruction and student age. Four-year-olds' school readiness generally improved as the proportion of child-initiated time increased, while three-year-olds showed a U-shaped pattern. The present findings add to the evidence that child-initiated instruction might support preschoolers' school readiness, although they also suggest this relation may not always be linear. They also point to the importance of examining instructional strategies in relation to student characteristics, in order to tailor strategies to the student population. The CAR has potential as a brief, practical measurement tool that can support program monitoring and professional development.

Healthy body, healthy mind: Long-term mutual benefits between classroom and sport engagement in children from ages 6 to 12 years

Past research suggests that the relationship between health and schooling is axiomatic. Physical activity, including sport participation, putatively facilitates school performance. However, the direction of this link lacks clarity. We examine the mutual links between sport and classroom engagement in 452 boys and 514 girls from ages 6 to 12 years. Participants are from the Quebec Longitudinal Study of Child Development, a prospective-longitudinal birth cohort. First, trajectories of classroom engagement from ages 6 to 10 years, assessed by teachers, were generated using latent class analysis. Second, analyses of covariance (ANCOVAs) compared leisure time physical activity, self-reported by children at age 12 years, across trajectories of classroom engagement. Third, ANCOVAs compared classroom engagement, measured by teachers at age 12 years, across trajectories of extracurricular sport between ages 6 to 10 years. We identified two classroom engagement trajectories: ‘High’ (77%) and ‘Moderate’ (23%). For girls, being in the ‘High’ trajectory predicted significantly higher levels of physical activity (F(1, 966) = 5.21, p < .05). For boys, being in the ‘Consistent participation’ extracurricular sport trajectory predicted significantly higher levels of classroom engagement (F(1, 966) = 6.29, p < .05). Our analyses controlled for pre-existing individual and family factors. Our findings suggest that sport participation and engaged classroom behavior positively influence each other during childhood. They support the pertinence of investing financial resources in youth intervention so that children can develop their potential both in sporting contexts and in the classroom to foster optimal growth and development.

Childhood exercise as medicine: Extracurricular sport diminishes subsequent ADHD symptoms

Extracurricular sport has been a valued educational investment to promote both physical and mental health in children and adolescents. Few longitudinal studies have tested whether extracurricular sport is associated with inattentive/hyperactive symptoms. Using a prospective-longitudinal birth cohort of 758 girls and 733 boys, we examined the prospective relationship between consistent middle childhood participation in extracurricular sport and subsequent ADHD symptoms. We hypothesized that engaging in extracurricular sport will promote reductions in symptoms. As a predictor, mothers reported on whether the child participated in sport or organized physical activities with a coach/instructor at ages 6, 7, 8, and 10 years. Developmental trajectories of the sport predictor, from ages 6 to 10 years, were generated using longitudinal latent class analysis. At age 12 years, sixth grade teachers reported on child ADHD symptom outcomes observed in the school setting over the last 6 months. ADHD symptoms were linearly regressed on trajectories of participation in organized sport in boys and girls, while controlling for pre-existing child and family characteristics. For girls, consistent participation in organized sport significantly predicted lower subsequent ADHD symptoms, compared with girls with low-inconsistent participation (unstandardized B = 0.07, p ≤ .05, 95% CI, 0.01-0.14). Early sustained middle childhood involvement in organized sport seems beneficial for the subsequent behavioral development of girls but no associations were found for boys. Middle childhood participation in structured venues that demand physical skill and effort with a coach or instructor may thus represent a valuable policy strategy to promote this aspect of behavioral development for girls.

Children's cortisol response to the transition from preschool to formal schooling: A review

This review examines the current state of knowledge regarding children's biological stress response during the transition from preschool to compulsory formal schooling, focusing on longitudinal studies that include repeated measures of cortisol concentrations in saliva or scalp hair. In all, eight independent studies (ten publications) were found and their results support the hypothesis that the transition from preschool to formal schooling coincides with an increase in cortisol concentration in both saliva and hair. Evidence of recovery (i.e. decrease in stress response over time) is more limited and suggests that it could take as many as 3-6 months before kindergarten children's cortisol concentration returns to baseline levels. However, important individual differences are observed. Potential predictors that have received some empirical support include child temperament (fearfulness/inhibition or surgency/extroversion) and prenatal maternal stress or anxiety. Very few studies, however, have examined whether there are actual functional consequences of individual differences in children's cortisol response associated with this transition. Finally, current methodological limitations and avenues for future studies are discussed.

Early Childhood Household Smoke Exposure Predicts Less Task-Oriented Classroom Behavior at Age 10

Secondhand tobacco smoke is considered a developmental neurotoxicant especially given underdeveloped vital systems in young children. An ecological test of its negative influence on brain development can be made by examining the prospective association between early childhood household smoke exposure and later classroom behavior. Using a longitudinal birth cohort, we examined the unique contribution of household tobacco smoke exposure to children’s subsequent classroom engagement at age 10. From child ages 1.5 to 7 years, parents of 2,055 participants from the Quebec Longitudinal Study of Child Development reported on household smoking by themselves and other home occupants. At age 10, fourth-grade teachers reported on the child’s classroom engagement. In terms of prevalence, 58% of parents reported that their children were never exposed to smoke in the home, while 34% and 8% of children were exposed to transient and continuous household smoke, respectively. Compared with never exposed children, those who were exposed to transient and continuous household smoke scored 13% and 9% of a standard deviation lower on classroom engagement in fourth grade, standardized B = −.128 (95% confidence interval = −.186, −.069) and standardized B = −.093 (95% confidence interval = −.144, −.043), respectively. Compared with their never exposed peers, children exposed to transient and continuous early childhood household smoke showed proportionately less classroom engagement, which reflects task-orientation, following directions, and working well autonomously and with others. This predisposition poses risks for high school dropout, which from a population health perspective is closely linked with at-risk lifestyle habits and unhealthy outcomes.

Feelings of Safety at School, Socioemotional Functioning, and Classroom Engagement

PURPOSE

Classroom engagement is a key indicator of student motivation, learning potential, and the eventual probability of persisting to high-school completion. This study investigated whether feeling unsafe at school interferes with classroom engagement and simultaneously considered whether this association is mediated by poorer student well-being in the form of experiencing symptoms of depression and demonstrating aggressive behavior problems.

METHODS

Data were from the Québec Longitudinal Study of Child Development, an ongoing study that began in 1998 with a population-based cohort of 2,120 Quebec 5-month-old infants. Structural equation modeling was used to test the central hypothesis that concurrent youth self-reported feelings of a lack of safety at school are associated with poorer teacher-reported student classroom engagement (at age 13 years) and the mediating role of emotional and behavioral problems. The model controlled for concurrent measures of victimization, the school safety climate, and earlier measures of students' academic adjustment.

RESULTS

The findings support the central hypothesis that youth who feel safer at school are also more engaged in the classroom (p ≤ .05). Students who felt safer demonstrated less depressive symptoms, but this only partly explained the association between feeling safe and being engaged.

CONCLUSIONS

Increasing student feelings of safety at school (e.g., by reducing victimization, improving the overall school and neighborhood safety climate) is likely to represent an effective strategy for promoting classroom engagement. Such interventions could also contribute to future academic achievement and high-school completion and decrease symptoms of mental health problems among youth.

Associations between Extracurricular Activity and Self-Regulation: A Longitudinal Study from 5 to 10 Years of Age

Purpose.

Health promotion in youth is likely to benefit from enhancing academic achievement and physical activity. The present study examines how kindergarten childhood self-regulation skills and behaviors predict involvement in both structured and unstructured physical and nonphysical extracurricular activities in the fourth grade. As a second objective this study also investigated how kindergarten childhood participation in extracurricular activities predicts classroom engagement, reflective of self-regulation, by the fourth grade.

Design.

Secondary analyses were conducted using prospective-longitudinal data.

Setting.

The Quebec Longitudinal Study of Child Development, Quebec, Canada.

Subjects.

Participants were randomly selected at birth from a stratified sample of 2694 born in Québec, Canada, between 1997 and 1998. Participants were included if they had complete data on teacher ratings of child self-regulation as measured by classroom engagement and parent ratings of sports participation (n = 935).

Measures.

Teachers reported self-regulation skills in children through a measure of classroom engagement. Parents provided reports of child participation extracurricular activities.

Analysis.

Ordinary least-squares regressions were conducted.

Results.

A higher-frequency kindergarten involvement with structured physical activities was associated with fourth-grade classroom engagement (β = .061, 95% confidence interval [CI]: .017, .104). Better kindergarten classroom engagement predicted more frequent participation in fourth-grade structured physical activities (β = .799, 95% CI: .405, 1.192) and team sports (β = .408, 95% CI: .207, .608).

Conclusion.

Results suggest mutual relations between physical activity and self-regulation from kindergarten to grade four. This suggests strong learning skills indicative of self-regulation and opportunities to participate in supervised physical activities or sports teams may help children develop healthy dispositions and behaviors in emerging adolescence.

24-Month-Old Children With Larger Oral Vocabularies Display Greater Academic and Behavioral Functioning at Kindergarten Entry

Data were analyzed from a population-based, longitudinal sample of 8,650 U.S. children to (a) identify factors associated with or predictive of oral vocabulary size at 24 months of age and (b) evaluate whether oral vocabulary size is uniquely predictive of academic and behavioral functioning at kindergarten entry. Children from higher socioeconomic status households, females, and those experiencing higher quality parenting had larger oral vocabularies. Children born with very low birth weight or from households where the mother had health problems had smaller oral vocabularies. Even after extensive covariate adjustment, 24-month-old children with larger oral vocabularies displayed greater reading and mathematics achievement, increased behavioral self-regulation, and fewer externalizing and internalizing problem behaviors at kindergarten entry.

Too Much Television? Prospective Associations Between Early Childhood Televiewing and Later Self-reports of Victimization by Sixth Grade Classmates

BACKGROUND

Using a birth cohort, this study aimed to verify whether televiewing at 29 months, a common early childhood pastime, is prospectively associated with self-reported victimization at age 12.

METHODS

Participants are 991 girls and 1006 boys from the Quebec Longitudinal Study of Child Development. The main predictor comprised parent-reported daily televiewing by their children at 29 months. In the sixth grade, children reported how often they experienced victimization by classmates in the past year. The authors conducted multivariate linear regression, in which child self-reports of victimization were linearly regressed on early televiewing and potential confounders.

RESULTS

Every SD unit increase (0.88 hours) in daily televiewing at 29 months predicted an 11% SD unit increase in self-reported peer victimization by sixth grade classmates (unstandardized B = .031, p < .001, 95% confidence interval = 0.014-0.042). This relationship was adjusted for child characteristics (gender, preexisting externalizing behaviors, baseline cognitive abilities, and televiewing at age 12) and family characteristics (family configuration, income, and functioning, and maternal education).

CONCLUSIONS

Daily televiewing time at 29 months was associated with a subsequent increased risk of victimization by classmates at the end of sixth grade, a period which represents a critical developmental transition to middle school. Youth who experience peer victimization are at an increased risk of long-term mental health issues, such as depression, underachievement, and low self-esteem. This prospective association, across a 10-year period, suggests the need for better parental awareness, acknowledgement, and compliance with existing recommendations put forth by the American Academy of Pediatrics.

Feasibility and validity of the structured attention module among economically disadvantaged preschool-age children

Rooted in the theory of attention put forth by Mirsky, Anthony, Duncan, Ahearn, and Kellam (1991), the Structured Attention Module (SAM) is a developmentally sensitive, computer-based performance task designed specifically to assess sustained selective attention among 3- to 6-year-old children. The current study addressed the feasibility and validity of the SAM among 64 economically disadvantaged preschool-age children (mean age = 58 months; 55% female); a population known to be at risk for attention problems and adverse math performance outcomes. Feasibility was demonstrated by high completion rates and strong associations between SAM performance and age. Principal Factor Analysis with rotation produced robust support for a three-factor model (Accuracy, Speed, and Endurance) of SAM performance, which largely corresponded with existing theorized models of selective and sustained attention. Construct validity was evidenced by positive correlations between SAM Composite scores and all three SAM factors and IQ, and between SAM Accuracy and sequential memory. Value-added predictive validity was not confirmed through main effects of SAM on math performance above and beyond age and IQ; however, significant interactions by child sex were observed: Accuracy and Endurance both interacted with child sex to predict math performance. In both cases, the SAM factors predicted math performance more strongly for girls than for boys. There were no overall sex differences in SAM performance. In sum, the current findings suggest that interindividual variation in sustained selective attention, and potentially other aspects of attention and executive function, among young, high-risk children can be captured validly with developmentally sensitive measures.

Classroom peer relationships and behavioral engagement in elementary school: the role of social network equity

Applying social capital and systems theories of social processes, we examine the role of the classroom peer context in the behavioral engagement of low-income students (N = 80) in urban elementary school classrooms (N = 22). Systematic child observations were conducted to assess behavioral engagement among second to fifth graders in the fall and spring of the same school year. Classroom observations, teacher and child questionnaires, and social network data were collected in the fall. Confirming prior research, results from multilevel models indicate that students with more behavioral difficulties or less academic motivation in the fall were less behaviorally engaged in the spring. Extending prior research, classrooms with more equitably distributed and interconnected social ties-social network equity-had more behaviorally engaged students in the spring, especially in classrooms with higher levels of observed organization (i.e., effective management of behavior, time, and attention). Moreover, social network equity attenuated the negative relation between student behavioral difficulties and behavioral engagement, suggesting that students with behavioral difficulties were less disengaged in classrooms with more equitably distributed and interconnected social ties. Findings illuminate the need to consider classroom peer contexts in future research and intervention focused on the behavioral engagement of students in urban elementary schools.

Early childhood television viewing and kindergarten entry readiness

BACKGROUND

Using a large population-based sample, this study aims to verify whether televiewing at 29 mo, a common early childhood pastime, is prospectively associated with school readiness at 65 mo.

METHODS

Participants are a prospective longitudinal cohort of 991 girls and 1,006 boys from the Quebec Longitudinal Study of Child Development with parent-reported data on weekly hours of televiewing at 29 mo of age. We conducted a series of ordinary least-squares regressions in which children's scores on direct child assessments of vocabulary, mathematical knowledge, and motor skills, as well as kindergarten teacher reports of socioemotional functioning, were linearly regressed on early televiewing.

RESULTS

Every SD increase (1.2 h) in daily televiewing at 29 mo predicted decreases in receptive vocabulary, number knowledge scores, classroom engagement, and gross motor locomotion scores, as well as increases in the frequency of victimization by classmates.

CONCLUSION

Increases in total time watching television at 29 mo were associated with subsequent decreases in vocabulary and math skills, classroom engagement (which is largely determined by attention skills), victimization by classmates, and physical prowess at kindergarten. These prospective associations, independent of key potential confounders, suggest the need for better parental awareness and compliance with existing viewing recommendations put forth by the American Academy of Pediatrics (AAP).
