There is increasing evidence supporting the effectiveness of the Early Start Denver Model (ESDM) for children on the autism spectrum. However, substantial variability in response to the ESDM has been reported across participants. We examined the plausible yet untested hypothesis that variations in the fidelity level of therapists delivering the…

Naturalistic developmental behavioral interventions (NDBIs) are evidence-based interventions for young children with autism spectrum disorder. There has been growing interest in implementing manualized NDBIs within the early intervention (EI) system without a clear understanding of how these programs and the broader strategies encompassed within…

Many autistic children require support to meet their learning needs. Given the heterogeneity within the autism spectrum it is plausible that different types of support might be better suited to different children. However, knowledge on what interventions work best for which children is limited. We examined the outcomes of autistic preschool-aged…

Children typically learn by attending to other people. Autism traits may impact access to social stimuli fundamental to early learning, increasing children's likelihood of a learning disability. Recent reports have highlighted that Autistic children from minority backgrounds have a higher likelihood of co-occurring intellectual disability. This…

We reexamined the efficacy of Pathways early autism intervention using generalized measures of social communication and language skills administered by an unfamiliar adult in a novel environment. Generalized measures improve on sources of measurement bias. Sixty-seven autistic children blocked on age (under versus over 3 years) were randomly…

Despite showing effects in well-controlled studies, the extent to which early intensive behavioral intervention (EBI) produces positive changes in community-based settings remains uncertain. Thus, our study examined changes in autistic symptoms and adaptive functioning in 233 children with autism receiving EBI in a community setting. The results…

We evaluated the effectiveness of a statewide Medicaid program providing in-home Early Intensive Behavioral Intervention services to young children with Autism Spectrum Disorder living in a rural southern state. Program effectiveness was assessed via the Assessment of Basic Language and Learning Skills-Revised (ABLLS-R). A multi-level growth model…

Play is critical in the development of cognitive and language skills in young children with autism; however, few studies have examined the impact of the intervention on the development of play skills. The current study aims to address the change in developmental skills, including play after participation in the JASPER intervention, and to examine…

This study investigates the effectiveness of a 6-month parent-mediated early intervention telehealth program for children with an autism spectrum disorder. The participants comprised a total of 27 parents. The findings showed that participation in the program promotes parents' empowerment and reduce parental stress and a general improvement in the…

Early intervention with parent participation is important for facilitating skill development in children with Autism Spectrum Disorder (ASD). However, many barriers delay or prohibit families from accessing care. We describe the development and acceptability of a novel, comprehensive, self-directed online program for caregivers of children with…

Telehealth is a promising modality for Part C early intervention (EI), services typically implemented face-to-face in home and community settings. Barriers to telehealth in EI reported prior to COVID-19 included lack of training and access to reliable internet. The abrupt telehealth shift at the onset of the pandemic did not permit a phased…

A growing evidence base supports early intensive behavioral intervention (EIBI) for young children with autism spectrum disorder. We have found only one study exploring the outcome of EIBI for children with Rett syndrome, which reported little effect. It suggested that future studies should employ more fine-grained outcome measures. We provided…

In Sweden, young autistic children typically attend community-based preschool programs, which may not be adapted to their needs. In the current study, stakeholders to autistic children receiving Early Intensive Behavioral Intervention were interviewed following a quasi-randomized study (#NCT03634761) aimed at improving the preschool program…

Mounting evidence supports several naturalistic developmental behavioral interventions (NDBI) for toddlers and preschoolers within inclusive childcare centers and preschools. However, these interventions pose many barriers to community implementation. As part of a larger project to create an adapted NDBI for early educators in childcare centers,…

This study aimed to provide initial validity and reliability of the "Measure of NDBI Strategy Implementation-Caregiver Change" ("MONSI-CC"), a novel measure that captures changes in caregivers' implementation of NDBI strategies during early intervention. The MONSI-CC was applied to 119 observations of 43 caregiver-child dyads…
