Data from the Early Childhood Longitudinal Study (ECLS-K; N = 6,420; 67.9% White/non-Hispanic, 15% Hispanic, 13% Black/non-Hispanic, 2% Asian, 3% Native American/Alaska Native; 25% of parents' income <$25,000, 25% = $25,001 to $45,000, 29% = $45,001 to $75,000, 20% = $75,001 or greater) were used to test structural equation models in which…

The present study investigated the relationship between two major components of executive functioning (EF) and externalizing behavior problems (EBP) during the early elementary years. More specifically, Working Memory (WM) and Cognitive Flexibility (CF) measured in kindergarten through second grade were used to predict teacher ratings of EBP in…

We analyzed a population-based cohort of 11,780 U.S. children to identify risk and protective factors by kindergarten predictive of being frequently verbally, social, reputationally, or physically victimized during the upper elementary grades. We also stratified the analyses by biological sex. Kindergarten children displaying externalizing problem…

Approximately one in 10 children in the United States is diagnosed with attention-deficit/hyperactivity disorder (ADHD), a disability that can negatively affect academic achievement, yet relatively few children with ADHD are in special education. To better understand factors that determine which students with ADHD are in special education, we…

Our goals in this study were to examine (a) the degree to which teacher perceptions of children's behavior in kindergarten (averaged across fall and spring for each child) predict retention by Grade 5 and (b) whether these relationships are moderated by student race, gender, or socioeconomic status (SES). Data from the Early Childhood Longitudinal…

As special education inclusion policies become more widespread, classroom compositions are changing in ways that affect all students. The present study fills a critical gap in the literature by documenting the extent to which having a classmate with an emotional disturbance (ED) is linked to kindergarteners' absences. Because having a classmate…

Drawing on a sample of twin children from the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B; Snow et al., 2009), the current study analyzed 2 of the most prominent predictors of externalizing behavioral problems (EBP) in children: (a) parental use of spankings and (b) childhood self-regulation. A variety of statistical techniques were…

Despite the vast body of research examining the relationship between full-day kindergarten attendance and children's outcomes, little is known about the effects of full-day kindergarten on children with disabilities (i.e., students with 1 of the 13 categories of disabilities recognized under federal law). This study fills this research void by…

Background/Context: Researchers, policymakers, and practitioners undoubtedly concur that missing school deteriorates student outcomes. And yet, in evaluating the deleterious effects of missing in-school time, empirical research has almost exclusively focused on absences, and the scant amount of empirical literature on tardiness has focused on…

Children with learning disabilities represent the largest category of students served within special education systems in schools, and are at increased risk for academic and psychosocial problems in comparison to peers without learning disabilities. While much of clinical practice and research focus has been on academic interventions,…

Research has demonstrated mixed results regarding differences in social and emotional characteristics between gifted and typical populations. The purpose of this secondary analysis of data from the Early Childhood Longitudinal Study: Birth Cohort (ECLS-B) is to investigate the affective characteristics of early mathematics and literacy ability…

Many studies have been conducted to address childhood behavior problems, but much remains unknown regarding the causes and factors that affect internalizing and externalizing problems in children. The purpose of the current research study was to examine the relationships between children's internalizing and externalizing behavior problems and (a)…
