Background: Early childhood is essential for the rapid development of self-regulation systems, shaped by brain maturation and parental discipline. Inadequate discipline can hinder this development, leading to behavioral, social, and long-term negative outcomes. Objective: This meta-analysis synthesizes research conducted over the last two decades,…

Self-regulation develops rapidly during early childhood and is essential for academic and social adjustment. However, previous research has attempted to define the conceptualization and structure of self-regulation differently, leaving the field with an incomplete picture. The nature of the relations between self-regulation and early child…

Healthy relationships between parents and teachers are essential to addressing children's emotional and behavioral concerns. The current meta-analysis examined the effects of family-school engagement interventions on parent-teacher relationships. Twenty-three group-design studies yielding 58 effects comprised the current sample. Random effect…

Externalizing behavior and low academic performance present key developmental challenges for school-age children, with the potential for these domains to predict each other over time, leading to worsened outcomes. Yet, previous studies have yielded inconsistent conclusions about the directional pathways between externalizing behaviors and academic…

Humans possess a tendency to rapidly and consistently make character evaluations from mere facial appearance. Recent work shows that this tendency emerges surprisingly early: children as young as 3-years-old provide adult-like assessments of others on character attributes such as "nice," "strong," and "smart" based…

This article synthesized evidence for the validity and reliability of the Strengths and Difficulties Questionnaire in children aged 3-5 years. A systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement guidelines was carried out. Study quality was rated using the Consensus-based Standards for the…

Empirical research supporting the contention that insecure attachment is related to internalizing behaviors has been inconsistent. Across 60 studies including 5,236 families, we found a significant, small to medium effect size linking insecure attachment and internalizing behavior (observed d = 0.37, 95% CI [0.27, 0.46]; adjusted d = 0.19, 95% CI…

This article examines associations between observed quality in preschool center classrooms for approximately 6,250 three- to five-year-olds and their school readiness skills at kindergarten entry. Secondary analyses were conducted using data from four large-scale studies to estimate the effects of preschool center quality and interactions between…

Clear associations of sleep, cognitive performance, and behavioral problems have been demonstrated in meta-analyses of studies in adults. This meta-analysis is the first to systematically summarize all relevant studies reporting on sleep, cognition, and behavioral problems in healthy school-age children (5-12 years old) and incorporates 86 studies…

Aim: The aim of this study was to investigate melatonin-related findings in autism spectrum disorders (ASD), including autistic disorder, Asperger syndrome, Rett syndrome, and pervasive developmental disorders, not otherwise specified. Method: Comprehensive searches were conducted in the PubMed, Google Scholar, CINAHL, EMBASE, Scopus, and ERIC…

Attachment theory suggests that children's attachment insecurity plays a key role in the development of anxiety. In the present study we evaluated the empirical evidence for the link between insecure attachment and anxiety from early childhood to adolescence. A meta-analysis of 46 studies, from 1984 to 2010, including 8,907 children, was…

The effectiveness of behavioural intervention programs for children with Autistic Spectrum Disorders was addressed by a meta-analysis, which reviewed 14 studies. The findings suggest that the behavioural programs are effective in improving several developmental aspects in the children, in terms of their treatment gains, and also relative to…

States and the federal government have invested in early care and education programs with an explicit goal of improving school readiness for low-income children. These investments, aimed at strengthening the quality of care and supporting families' access to high-quality settings, are based in part on a confluence of research findings showing a…

Background: The differential effectiveness of parent training has led researchers to examine a variety of child, parent, and familial variables that may predict treatment response. Studies have identified a diverse set of child, parent psychological/behavioral and demographic variables that are associated with treatment outcome and dropout.…
