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…

Social communication deficits are one of the defining features of autism spectrum disorder. In schools, social communication deficits are assumed to be due to a skill acquisition issue and remediated through social skills instruction; however, social skills instruction has been fairly criticized, particularly by those in the autistic community, as…

Purpose: Despite group-level improvements in active engagement and related outcomes, significant individual variability in response to early intervention exists. The purpose of this preliminary study was to examine the effects of a group-based Naturalistic Developmental Behavioral Intervention (NDBI) on active engagement among a heterogeneous…

Naturalistic developmental behavioral interventions are an empirically supported intervention approach for young autistic children. Despite the prevalence of disruptive behaviors among autistic children, most manualized caregiver-mediated naturalistic developmental behavioral interventions include limited formal guidance on when and how to manage…

Children with autism spectrum disorder often display some form of challenging behavior and have complex communication needs. Functional communication training is an evidence-based practice that (a) decreases challenging behavior and (b) increases appropriate communicative behavior. Recent research has demonstrated how using augmentative and…

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…

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…

The neurodiversity model of disability is a relatively new approach to teaching and working with autistic individuals. As a result, many interventions align with earlier models of disability, such as the medical and social models, and aim to assimilate autistic individuals among their neurotypical peers rather than celebrate their differences as…

Parent-implemented Naturalistic Developmental Behavioral Interventions (NDBIs), rooted from applied behavioral and developmental sciences, focus on empowering families by training and coaching natural change agents to embed evidence-based strategies during regular events or contexts (e.g., play time). No research, however, has relied on…

Functional communication training (FCT) is a well-established, evidence-based practice used to address challenging behavior among individuals across settings, ages, and disability categories. However, the research is limited on the implementation of FCT in inclusive school settings for students with intellectual and developmental disabilities. The…

This triple-arm, double-blind, randomized clinical trial investigated the effect of multisession prefrontal transcranial direct current stimulation (tDCS) on social functioning in individuals with autism spectrum disorder (ASD). A total of 105 individuals (age 14-21 years) diagnosed with ASD were randomized into the active-tDCS, sham-tDCS, and…

The prevalence of Autism Spectrum Disorders (ASD) has resulted in research on treatment efficacy, lending itself to quantitative analyses. In contrast, ethnographic studies have offered the benefits of analyzing lived experiences and exploring the uniqueness of ASD individuals. Using the Linguistic Ethnography (LE) perspective, this case study…

Applied behavior analysis (ABA) is considered an applied science under the umbrella of behavior analysis and was accepted into the mainstream science in the mid-1900s. An increase in the prevalence of autism gave rise to the need for evidence-based social skills curricula. Previous research indicated many children respond well to video modeling…

Social-communication deficits associated with autism spectrum disorder often lead to undesirable outcomes in other domains, such as interpersonal relationships, employment, and participation in community activities. Parents may be ideal implementers of interventions to address these deficits when provided with instruction that is efficacious and…

Currently, the rate of individuals with autism spectrum disorder (ASD) is growing and further research is needed to understand what evidence-based practices are effective for this population. To contribute further to the already existing literature, the three studies expand on previous reviews and studies by adding information on whom these…
