Three generations of developmental epidemiologically based randomized field trials of the Good Behavior Game (GBG) have been delivered to Baltimore elementary schools. With the collaboration of family and community partners, all three trials were directed at decreasing proximal targets of aggressive behavior and improving learning in first-grade…

Classroom observations have long been considered a necessary component of Attention-Deficit/Hyperactivity Disorder (ADHD) evaluations. Yet, research evaluating the utility of observational ratings in ADHD assessment is limited. This study examined the contributions of the Behavioral Observation of Students in Schools (BOSS) to ADHD assessment by…

A randomized controlled trial was used to examine the impact of an attachment-based, teacher-child, dyadic intervention (Banking Time) to improve children's externalizing behavior. Participants included 183 teachers and 470 preschool children (3-4 years of age). Classrooms were randomly assigned to Banking Time, child time, or business as usual…

The primary purpose of the 2017-2018 NC Pre-Kindergarten (NC Pre-K) Evaluation was to examine the effectiveness of the NC Pre-K Program using a randomized controlled trial (RCT) design. The major issue addressed by this type of study is around the benefits of offering children access to enrollment in NC Pre-K. An RCT is considered the…

The primary purpose of the 2017-2018 NC Pre-Kindergarten (NC Pre-K) Evaluation was to examine the effectiveness of the NC Pre-K Program using a randomized controlled trial (RCT) design. Because children are randomly assigned to either receive NC Pre-K (treatment) or not (control) in an RCT, differences in outcomes can be causally attributed to…

Background: There is an increased focus on randomized trials for proximal behavioral outcomes in early childhood research. However, planning sample sizes for such designs requires extant information on the size of effect, variance decomposition, and effectiveness of covariates. Objectives: The purpose of this article is to employ a recent large…

For children with the most serious and persistent academic and behavior problems, parent involvement in education, particularly teacher perceptions of involvement, is essential to avert their expected long-term negative outcomes. Despite the widespread interest in and perceived importance of parent involvement in education, however, few…

Research has shown that teacher effectiveness is the most important school-based factor that influences student outcomes, including student achievement. Studies have also shown that there is substantial variation in teacher effectiveness, such that some teachers improve student outcomes at a much faster rate than others. The strong influence of…

For children with the most serious and persistent academic and behavior problems, parent involvement in education, particularly teacher perceptions of involvement, is essential to avert their expected long-term negative outcomes. Despite the widespread interest in and perceived importance of parent involvement in education, however, few…

The purpose of this study was to evaluate the efficacy of a universal social skills program, the Social Skills Improvement System Classwide Intervention Program (SSIS-CIP; Elliott & Gresham, 2007), for students in first grade. Classrooms from 6 elementary schools were randomly assigned to treatment or business-as-usual control conditions.…

This group randomized controlled trial (RCT) evaluated the efficacy of Incredible Years Teacher Classroom Management Program (IY TCM) on student social behavioral and academic outcomes among a large diverse sample of students within an urban context. Participants included 105 teachers and 1817 students in kindergarten to third grade. Three-level…

A wide and rich body of literature has identified the family as the key context influencing children's development. In response, school districts and policymakers have sought to engage parents in children's learning, particularly low-income families. Meta-analyses conclude that efforts to engage low-income parents do improve students' academic…

This article describes the use of "Teacher Impression Journals" during a larger study that examined the efficacy of an intervention program designed to promote kindergarteners' positive attitudes toward peers with disabilities (i.e., the "Special Friends" program). The journals were designed to gather information about…

The current study examines classroom-level peer behavioral regulation skills and their implications for children's school readiness outcomes. Specifically, this study will answer the following research questions: (1) Is the average level of peers' behavioral regulation skills in a classroom in the fall associated with growth in children's school…

This study reports the results of a randomized controlled trial examining the effect of Conjoint Behavioral Consultation (CBC), a family-school partnership intervention, on children's behaviors, parents' skills, and parent-teacher relationships in rural community and town settings. Participants were 267 children, 267 parents, and 152 teachers in…
