Autism diagnosis before age three to expedite access to critical services is a public health priority in the United States. Still, the average age of autism diagnosis is 49 months with substantial variability across states. By examining policy--defined as laws, regulations, procedures, administrative actions, incentives, or voluntary practices of…

We conducted a multi-pronged investigation of different types of reporting bias in autism early childhood intervention research. First, we investigated the prevalence of reporting failures of completed trials registered on clinicaltrials.gov, and found that only 7% of registered trials were updated with results on the registration platform and…

There is little research regarding autistic adult, parent and professional perspectives on support goals for young autistic children. A total of 87 autistic adults, 159 parents of autistic children, and 80 clinical professionals living in New Zealand and Australia completed a survey about the appropriateness and importance of common support goals…

This study examined the feasibility of implementing the Screening Tool for Autism in Toddlers, an interactive Level-2 screen for autism spectrum disorder, within Part C Early Intervention settings. Participants included 69 Early Intervention providers (M age = 43.3 years, 93.7% females, 92.4% Whites) from nine programs who attended a one-day…

Caregiver coaching is an evidence-based practice for autistic children that is poorly implemented in community-based early intervention. Previous studies have identified factors that influence implementation of caregiver coaching in early intervention; however, multi-informant (e.g., caregiver, provider, leadership) qualitative research is…

This article outlines a stakeholder-created research agenda to guide future early intervention research for autistic children. We collaborated with 10 autism service providers, 10 parents of individuals with autism, and 10 autistic people across a total of 18 small group and 2 inter-group meetings occurring over 2 years. Together, we synthesized…

Both expressive and receptive language difficulties in autism emerge early and significantly have an impact on social functioning and quality of life. Despite their wide heterogeneity, autistic language abilities can be stratified into three distinct profiles. Language unimpaired exhibit near-typical verbal performance, language impaired show…

Autistic advocates emphasise the need for neurodiversity-affirming and strengths-based approaches to support services; however, little is known about broader community perspectives regarding the appropriateness of offering early support services to autistic children. This co-designed mixed-methods study employed surveys to gather insights from 253…

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…

The "1,2,3,emoció!" is a universal preschool program of emotional education for children aged 3-5 years that has positive effect on emotional competence. The objective of this study was to evaluate the effectiveness of this program specifically in 3- to 5-year-old children with autism spectrum conditions. The effectiveness was evaluated…

There is a great demand for quality early intervention services for autistic children and their families. Caregiver-mediated interventions are critical components of evidence-based early intervention. However, their implementation in publicly funded systems is often done with poor fidelity. Qualitative evidence suggests that family characteristics…

Naturalistic Developmental Behavioral Interventions (NDBIs) have a strong and growing evidence base. Yet, NDBIs are not implemented on a wide scale within early intervention programs for children on the autism spectrum. Potential reasons for the slow adoption of NDBIs likely stem from the differing theoretical orientations of behavioral and…

To address the variability of naturalistic developmental behavioral intervention outcomes, the current study sought to isolate the effects of the instructional strategies of caregiver-mediated naturalistic developmental behavioral interventions. In this comparative efficacy trial, mothers of 111 autistic children (18-48 months) were randomized to…

Despite consensus on the importance of early detection and intervention for autistic children, health disparities exist, limiting access to timely services. One specific service type in the United States is Individuals with Disabilities Education Act, Part C Early Intervention programs, which are federally funded interventions for children…

Robust evidence supports the efficacy of early autism intervention. Despite broad consensus that earlier intervention leads to better outcomes, evidence for this has been limited to correlational studies. This study examined timing effects of the Early Social Interaction (ESI) model, a parent-implemented intervention, using a complete crossover…
