Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

Fragile X syndrome (FXS), the leading heritable cause of intellectual disability, has a co-occurrence rate of autism spectrum disorder (ASD) estimated at ~60%. The onset and rates of motor development in FXS are slower relative to neurotypical development, and even more so in the context of co-occurring FXS + ASD. Extant evidence suggests these…

Joint attention and imitation are thought to facilitate a developmental cascade of language and social communication skills. Delays in developing these skills may affect the quality of children's social interactions and subsequent language development. We examined how responding to joint attention and object imitation skills predicted rate of…

The aims of this study were to (a) characterize the prevalence and interrelationship of Individualized Education Program (IEP) goals in academic (reading, writing, math) and developmental (language, social skills, behavioral) domains in a large U.S. national sample of autistic children across the elementary and secondary grade levels and (b)…

The current study was a secondary analysis of cross-sectional data collected in New Zealand. Parents (n = 291) of an autistic child completed an online survey that included temporal/demographic questions relating to the parent and child, and parent ratings of the child's core ASD symptoms, their parenting stress, and psychological well-being.…

Difficulties in communication during social interactions are a feature of the diagnosis of autism spectrum disorder (ASD). Little is known about the communication abilities of minimally-verbal (MV) individuals, which comprises one-third of autistic individuals. Natural language sampling (NLS) provides an optimal approach to capture communication…

Evidence-based early interventions for autism spectrum disorder (ASD) have been shown to improve child outcomes and quality of life (Lord et al., 2018; Reichow et al., 2018; Smith & Iadarola, 2015). However, response to intervention is variable across both children and implementation contexts. Understanding factors that influence this…

Social communication and executive functioning challenges as well as co-occurring anxiety/depression may make acquiring the skills needed to manage daily life tasks difficult for diploma-track autistic youth, thus limiting their participation in adult roles. This study describes the associations between executive function, social communication…

Applied behavior analysis (ABA) interventions are delivered using a tiered-service model, in which supervisors with higher levels of experience, education, and certification oversee clinicians who provide direct intervention for individuals with Autism Spectrum Disorder (ASD). Despite the base of empirical support for ABA constructed over several…

This study explores Korean-American parents' perceptions on successful transition to kindergarten (TTK) for their child on the autism spectrum. It further examines challenges experienced during this process, and possible predictors for their challenges. Findings from an online survey (N = 212) indicate that participants consider their child's…

We surveyed New Zealand parents of autistic children to identify their perceived barriers and facilitators to accessing support services, including the influence of a family's level of financial resourcing. A total of 173 completed surveys were analysed. Service pathway factors were the greatest barrier experienced by participants, whereas…
