Parenting programs have been shown to be effective in preventing and reducing externalising problems in young children. Despite their efficacy, the low rate of initial parental engagement in these programs is a major challenge for clinicians and researchers. Few studies have examined factors associated with rates of initial engagement in parenting…

Identifying effective methods that can counteract seasonal trends in learning loss is essential to ensure continuous literacy growth of young learners. Computer-assisted instruction (CAI) is a solution for providing an effective summer literacy program that could help offset summer learning loss. In this study, four-year-old students from South…

There is a need for robust evidence about which educational interventions work in preschool to foster children's cognitive and socio-emotional learning (SEL) outcomes. Lab-based individually randomized experiments can develop and refine such interventions, and field-based randomized experiments (e.g., cluster randomized trials) evaluate their…

Empowerment is a core construct in health behavior and an emerging trend in pediatrics. Although it has been suggested as an approach that may promote the person's participation in health care decisions and positive outcomes, little is known about the nature and effectiveness of interventions to support empowerment in families and preschool-age…

Background: The language of the science curriculum is complex, even in the early grades. To communicate their scientific observations, children must produce complex syntax, particularly complement clauses (e.g., "I think it will float;" "We noticed that it vibrates"). Complex syntax is often challenging for children with…

Background: Poverty-related disparities in school readiness are well documented (Dreyer, 2020). Increasing cognitively stimulating parenting practices can contribute greatly to addressing such disparities, and therefore represent a key modifiable target for preventive interventions beginning early in life (Brooks-Gunn & Markman, 2005).…

Background: A total of 68% of pre-school children with cleft palate have speech problems requiring speech therapy. There is a lack of access to regular targeted therapy. Parent training leads to positive outcomes in early communication skills in cleft palate and non-cleft speech disorders. Connected health has been used to address inadequate…

This paper reviews research on the design and effectiveness of preschools in the United States. Three randomized controlled trials that enrolled roughly 350 total children in demonstration studies during the 1960s and 1970s shape much of the current discussion of preschool. We examine what these studies and more recent ones based on random…

Tender Shoots is a randomized controlled trial (RCT) for parents aimed at improving preschool children's oral language skills relevant for later reading. Parents of 72 preschool children (M = 50 months) were randomly assigned to either a Rich Reading and Reminiscing (RRR) condition, a Strengthening Sound Sensitivity (SSS) condition, or an…

Early intervention efforts have been effective in reducing disruptive behaviors and the probability of poor developmental outcomes. Early interventions include common practice elements to improve social functioning and decrease problem behaviors that disrupt the teaching-learning process. The First Step Next intervention has been well validated…

Background: Recent evidence suggests that pre-school children with co-occurring phonological speech sound disorder (SSD) and expressive language difficulties are at a higher risk of ongoing communication and literacy needs in comparison with children with these difficulties in isolation. However, to date there has been no systematic or scoping…

The primary aim of this study was to assess the efficacy of a childcare-based intervention in increasing child physical activity by allowing children unrestricted access to outdoor areas for free-play when structured activity is not taking place. A randomized controlled trial was conducted in six childcare services. Intervention services provided…

This article assesses the likely generalizability of educational treatment-effect estimates from regression discontinuity designs (RDDs) when treatment assignment is based on academic pretest scores. Our assessment uses data on outcome and pretest measures from six educational experiments, ranging from preschool through high school, to estimate…

Background: Children with language comprehension difficulties are at risk of educational and social problems, which in turn impede employment prospects in adulthood. However, few randomized trials have examined how such problems can be ameliorated during the preschool years. Methods: We conducted a cluster randomized trial in 148 preschool…
