For the past 25 years, I have led multiple group-randomized trials, each focused on a specific underserved population of youth and each one evaluated health effects of complex interventions designed to prevent high-risk behaviors. I share my reflections on issues of intervention and research design, as well as how research results fostered my…

Secondary data analysis was employed to scrutinize factors affecting sample retention in a randomized evaluation of an early childhood intervention. Retention was measured by whether data were collected at 3 points over 2 years. The participants were diverse, immigrant, and U.S.-born families of color from urban, low-income communities. We…

Background: Community health worker (CHW) interventions are known to be an effective strategy to improve health behaviors and outcomes in relation to diabetes, particularly for racial/ethnic communities. Although understanding the function of identity with same race/ethnicity among clients of CHW interventions could contribute to more effective…

Objective: This study examined the efficacy of the Parent and Child Enhancement (PACE) program on child learning, child behavior problems, and parental stress, using randomized controlled trial design, in social services centers. Methods: Eligibility criteria were (1) children aged 2 years at program commencement, (2) low-income, new immigrant, or…

Rates of participation in intervention research have not been extensively studied within autism spectrum disorder. Such research is important given the benefit of early intervention on long-term prognosis for children with autism spectrum disorder. The goals of this study were to examine how family demographic factors predicted treatment…

Young people from areas of socioeconomic disadvantage (SED) are more likely to present with language difficulties, particularly vocabulary difficulties. Studies have shown the effectiveness of vocabulary interventions for children with language impairment but not for adolescents from areas of SED. This article aims to establish the effectiveness…

The intervention evaluated here is one of two "youth social action" projects jointly funded by the Education Endowment Foundation, the U.K. Cabinet Office, the Pears Foundation and the Stone Family Foundation. It was delivered by the Youth United Foundation (YUF) and involved uniformed youth organisations being established in schools in…

Research Findings: This study investigated how mean classroom-level shyness scores moderated the impacts of "INSIGHTS" into "Children's Temperament" on instructional support and students' math and reading skills in kindergarten and 1st-grade classrooms. "INSIGHTS" is a temperament-based social-emotional learning…

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,…

Performance-based scholarships were developed to help tackle some of the financial obstacles facing students in the postsecondary education system. In general, these scholarships aim to help reduce the financial burdens of low-income college students, and are structured to help incentivize good academic progress. Performance-based scholarships…

Persistent inequalities in the academic learning trajectories of underserved students have led to a growing interest in interventions for young children who are at higher risk for academic difficulties later on. This study's primary goal was to understand how the integration of video, computer games and associated hands-on activities impacts…

Abracadabra (ABRA) is a 20-week online literacy program composed of phonic fluency and comprehension activities based around a series of age-appropriate texts.
