In this systematic review, we examined the rigor and outcomes across 27 object play intervention studies using single-case research methodology. We focused on studies including children age 5 years or younger and examined several descriptive characteristics including materials, instructional packages, and settings. We also analyzed the…

The purpose of this study was to examine the efficacy of the system of least prompts (SLP) for increasing the levels of play behaviors in four young children with disabilities. A multiple probe across participants' single case research design was used to examine the relation between SLP and child-targeted behaviors. The results demonstrated that…

This historical review explores the development of the literature base of single-case intervention research associated with the promotion of social outcomes for young children under the age of 9. Research studies are included from the seminal study conducted in 1956, continuing through 2019. Trends and patterns in study components are noted, such…

We examined the use of an intervention package consisting of the system of least prompts (SLP), visual schedules, peer models, and contingent reinforcement to teach four children with disabilities to independently play board games and communicate with their typically developing peers. We found the intervention package with individual adaptations…

The purpose of this article was to describe 2 studies that examined the relation between descriptive praise and generalized diversity of forms and colors used during art activities in young children. Study I used a true reversal design to examine the relation between descriptive praise and diversity during art activities. All 4 children had small…

We examined an intervention package using peer modeling, systematic prompting, and contingent reinforcement to increase the frequency and complexity of board game play and social behaviors in young children with disabilities. Four children with or at risk for disabilities participated with their typically developing peers. Results indicated a…

Research in early intervention/early childhood special education (EI/ECSE) is focused on identifying effective practices related to positive outcomes for young children with disabilities and their families. Individual responses to evidence-based practices are often variable, and non-responders are common. Single case research (SCR) might be…

Young children with challenging behavior may require individualized interventions to facilitate improved outcomes. Visual activity schedules (VAS) have been well documented for improving engagement, transition, and recreation behaviors with children with autism spectrum disorder (ASD) and intellectual disabilities (ID). However, children…

The purpose of this article was to describe a comprehensive and updated review of available classroom and parenting social-emotional programs for young children. The review analyzed 10 classroom curricula and 8 parenting interventions focused on social-emotional development and the research associated with each. The efficacious adoption criteria…

Increasing numbers of children with autism receive education services in settings with their typically developing peers. In response to this shift in the location of services, there is a growing body of research identifying evidence-based practices for young children with autism in inclusive early childhood classrooms. The purpose of this paper is…

Although comparison studies are important in early intervention/early childhood special education (EI/ECSE), results of well-designed comparison studies are likely to be unpublished because of undifferentiated or differently differentiated results across participants. The purpose of this article is to highlight the utility of comparison designs in…

Play is a "critical" intervention goal for children with autism in inclusive settings because it sets the occasion for social interactions and communication with peers, caregivers, and teachers, and provides an authentic context for embedding instruction. Furthermore, several research studies have found "pretend" play to be a predictor of social…

The purpose of this article is to raise the profile of play so that it is an important domain of concern for serving children with delays and disabilities, just as are the other five domains specified in federal law. A rationale for the integration of the behavioral perspective and the constructivist perspective is presented to contribute clarity…

In this paper, we examine the link between evidence-based practice and social validity by describing five examples from our own research where social validity measures resulted in data that were essential to both a clinical and research agenda on evidence-based practice. Social validity data are reviewed in the context of behavioral skill training…

The shortage of highly qualified speech language pathologists (SLPs) with specialized training in early intervention and early childhood special education (EI/ECSE) is a pressing issue facing the field and dramatically impacts young children's social and academic success. SLP personnel preparation programs focused on training specialists in…
