Prevent-Teach-Reinforce for Young Children (PTR-YC) is a standardized model of positive behavior support designed to deliver individualized interventions for preschool-aged children with severe and persistent challenging behaviors. A randomized controlled trial was conducted to compare effects of PTR-YC with those of a "business as…

Telehealth training may benefit parents' use of early intervention for children with autism spectrum disorder (ASD). This study is one of the few randomized trials to compare telehealth parent training in the Early Start Denver Model (P-ESDM) with a community treatment-as-usual, early intervention program. Parents were randomized to 12 weekly…

A randomized controlled trial was conducted to evaluate effects of the Joint Attention Mediated Learning (JAML) intervention. Toddlers with autism spectrum disorders (ASD) aged 16-30 months (n = 144) were randomized to intervention and community control conditions. Parents, who participated in 32 weekly home-based sessions, followed a mediated…

This randomized controlled trial in 55 low-performing schools across Florida compared 2 early literacy interventions--1 using stand-alone materials and 1 using materials embedded in the existing core reading/language arts program. A total of 3,447 students who were below the 30th percentile in vocabulary and reading-related skills participated in…

The purpose of this study was to investigate the effects of an early numeracy intervention delivered by kindergarten teachers to students identified as having mathematics difficulties. A multigroup growth-modeling-with-random-assignment-to-intervention-condition design was employed. Thirty-two teachers were randomly assigned to the treatment or…

Research Findings: Mental state verbs (MSV), a component of literate and academic language, may facilitate vocabulary growth, as they relate to metacognitive and metalinguistic awareness as well as decontextualized talk, all of which have been associated with vocabulary growth. In this study, we examined teacher MSV use in group content…

Purpose: We investigated a small-group intervention designed to teach vocabulary and comprehension skills to preschoolers who were at risk for language and reading disabilities. These language skills are important and reliable predictors of later academic achievement. Method: Preschoolers heard prerecorded stories 3 times per week over the course…

This study described the commenting practices of Head Start teachers, and the relationship of comments to the expressive and receptive vocabulary growth of children with below-the-mean language ability across one year of preschool. Participants included 52 Head Start teachers, and 489 children (247 early intervention candidates and 242 Head Start…

Young children removed from institutions and placed into foster care or adoptive homes have been shown to experience significant gains in IQ relative to children who remain in institutions. Less is known about the long-term impact of severe early deprivation on development in late childhood. Data are presented from a follow-up of children at 12…

Early interventions aim at promoting a good mother-child relationship as basis for a good socio-emotional development, especially in high-risk populations, and at correcting already unfavorable patterns of interaction and are common today. Insecure attachment, both of the child and of the mother, has been identified as a risk factor for early…

Head Start enhances school readiness during preschool, but effects diminish after children transition into kindergarten. Designed to promote sustained gains, the Research-based Developmentally Informed (REDI) Parent program (REDI-P) provided home visits before and after the kindergarten transition, giving parents evidence-based learning games,…

Many preschool language-focused interventions attempt to boost language and literacy skills in young children at risk in these areas of development, though the long-term effects of such interventions are not well-established. This study investigated kindergarten language and reading skills, specifically the subcomponents of vocabulary, decoding,…

We investigate the classwide efficacy of INSIGHTS, a universal social-emotional learning intervention for early elementary grades, on observed teacher practices and student behaviors. Twenty-two elementary schools (87% free/reduced lunch) were randomly assigned to INSIGHTS or an attention-control condition. Kindergarten and first-grade classrooms…
