The COVID-19 context has created the most severe disruption to education systems in recent history. Its impact on child development was estimated comparing two cohorts of 4- to 6-year-old Uruguayan children: control (n = 34,355, 48.87% girls) and COVID cohort (n = 30,158, 48.95% girls) assessed between 2018 and 2020 in three waves, by a routinely…

This study investigates the effectiveness of the PRIMA antibullying program for elementary education using a cluster-randomized trial with two experimental conditions (with and without student lessons) and a control group. Students of 31 schools participated in the study (N = 3,135; M[subscript age] = 10 years). Multilevel regression analyses…

Tracing developmental pathways of immigrant-origin adolescents, this 3-year longitudinal study (2012-2015) examined within-person changes in cultural orientations and their consequences for school adjustment. Multivariate latent growth mixture modeling confirmed multiple pathways of integration, revealing variable acculturative changes along dual…

This article provides a systematic review and meta-analysis of the current evidence for universal school-based (USB) social and emotional learning (SEL) interventions for students in kindergarten through 12th grade available from 2008 through 2020. The sample includes 424 studies from 53 countries, reflecting 252 discrete USB SEL interventions,…

Adolescence is characterized as a period of social reorientation toward peer relationships, entailing the emergence of sophisticated social abilities. Two studies (Study 1: N = 42, ages 13-17; Study 2: N = 81, ages 13-16) investigated age group differences in the impact of relationship reciprocation within school-based social networks on an…

Minority and majority elementary school students from a Native American reservation (N = 188; K-fifth grade; 5- to 10-year-olds) completed tests of academic self-concepts and self-esteem. School grades, attendance, and classroom behavior were collected. Both minority and majority students exhibited positive self-esteem. Minority students…

Data from the National Institute of Child Health and Human Development (NICHD) Study of Early Childcare and Youth Development (N = 1,364) were used to investigate children's trajectories of academic and social development across 1st, 3rd, and 5th grades. Hierarchical linear modeling was used to examine within- and between-child associations among…

To assess how they compared themselves to peers, elementary school students were observed in class and interviewed over a three-year period. Found that overt forms of social comparison were most frequent among younger children, and subtle forms among older children. With increasing age, children were likely to see subtle forms of social comparison…

Three studies replicated and extended Dweck's findings regarding young children's responses to challenging achievement situations. Findings indicated that a composite of cognitive, behavioral, and affective helplessness indices at kindergarten age predicted helplessness 1 and 5 years later, above and beyond gender and kindergarten task ability.…

Examined academic and behavioral problems as a function of two dimensions by which rejection may vary over time: chronicity and temporal proximity. Suggests that all levels of rejection were associated with greater absenteeism from school, and more chronic and proximal experiences of rejection were associated with elevated externalizing behavior…

Compared outcomes of middle-school-age children born at very low (less than 750-g) or low birthweights (750 to 1,499-g) and full-term. Found that the very-low-weight group fared less well at school age than the low weight and term groups on cognitive functioning, achievement, behavior, and academic performance. Those without neurosensory disorders…

Identified groups of economically disadvantaged children showing high externalizing behavior in first grade that persisted (persistent) or decreased (improver) in third grade, or low first- grade levels that were stable (unproblematic) or increased (new problem) in third grade. Found that verbal ability, behavioral impulsivity, parent…
