Limited research has examined the active ingredients and mechanisms of change of naturalistic developmental behavioral interventions (NDBIs). The present study used an exploratory sequential mixed-methods design to develop a comprehensive Theory of Change of Project ImPACT, an empirically supported NDBI. We used qualitative data from interviews…

Younger siblings of autistic children are at a high likelihood (HL) of autism, language, and/or cognitive delays. Vocal complexity, a continuous measure of the developmental maturity of vocal communication, is facilitated by parent-child interaction and predicts language outcomes. This study examined whether parents' intervention fidelity to…

This article describes the development and use of a first of its kind statewide implementation of an adapted Early Start Denver Model (ESDM). Supported by a collaborative partnership between stakeholders that included families, state agencies, and a state university, the intervention was implemented within the existing framework of a northeastern…

We used a multiple baseline across strategies design to determine the effect of technology-enhanced performance-based feedback on parent's use of preventive strategies to address children's challenging behaviors for two parent--child dyads. A father, mother, and each of their young children participated. We also measured associated child outcomes…

Over the past decade, a newer class of interventions has emerged specifically designed for young children with or at high likelihood of autism, which are called Naturalistic Developmental Behavioral Interventions (NDBIs). NDBIs are particularly well-suited as a discipline agnostic, primary intervention for young children with autism and other…

Functional communication training (FCT) is an evidence-based intervention that while often effective, can result in rote responding, reduced generalizability of target behavior, and resurgence of challenging behavior (CB) during treatment lapses. Lag schedules of reinforcement have been successfully used to address these concerns. We applied an…

A majority of children's language learning experiences occur in inclusive early child care and education settings. Few evidence-based professional development (PD) programs exist to empower early childhood education providers to use language instruction practices with children in inclusive classrooms. There is little research on providers'…

Naturalistic developmental behavioral intervention (NDBI) strategies appear to be well-suited for implementation by preschool teachers of young children ages 3 through 5, yet research exploring NDBI implementation within this specific context is extremely limited. We applied an implementation science framework to examine reported knowledge,…

Few studies examine the effectiveness of community-based early interventions in unselected samples of autistic children, especially those from minoritized backgrounds. These types of studies require attention to strategies for recruitment, retention, data collection, and support for community providers beyond those used in university-based trials.…

Despite substantial empirical support, correlates of retention and success in community-based parent-child interaction therapy (PCIT) implementation are not well defined. Widespread application of PCIT necessitates improved understanding of intervention components relating to family outcomes beyond highly controlled research trials. Using data…

Many young children entering early childhood programs demonstrate challenging behaviors that place them at risk for emotional/behavioral disorders (EBDs), which impact their future success in school. The purpose of this study was to conduct a conceptual replication of BEST in CLASS by examining child outcomes from BEST in CLASS--Web, a web-based…

Group contingencies have been used successfully to modify a variety of behaviors for children with diverse characteristics across multiple settings. However, these interventions have not been applied to increase social interactions (SI) between typically developing children and those with multiple or severe disabilities (MSD). Furthermore, little…

The Early Start Denver Model (ESDM) has been gaining popularity as a comprehensive treatment model for children ages 12 to 60 months with autism spectrum disorders (ASD). This article evaluates the research on the ESDM through an analysis of study design and purpose; child participants; setting, intervention agents, and context; density and…

The current study examined the feasibility and initial efficacy of the Summer Treatment Program for Pre-kindergarteners (STP-PreK) with 37 preschoolers with autism spectrum disorder (ASD) and externalizing behavior problems (EBP). Parents and teachers reported on children's behavior, social/adaptive skills, and self-regulation. Children completed…

Social narratives (e.g., Social Stories™) are common antecedent-based interventions promoted for the purposes of improving prosocial behaviors and reducing challenging behavior for children with and without disabilities. Although they are commonly prescribed and used, their effectiveness has almost exclusively been assessed for children with…
