Individuals with autism spectrum disorder and average IQ exhibit a widening discrepancy between lagging adaptive skills relative to their cognitive potential, but it is unknown when this discrepancy emerges in development. To address this important question, we measured adaptive and cognitive skills longitudinally, from 12-36 months, in 96…

The last decades of neuroimaging research has revealed atypical development of intrinsic functional connectivity within and between large-scale cortical networks in autism spectrum disorder, but much remains unknown about cortico-subcortical developmental connectivity atypicalities. This study examined cortico-striatal developmental intrinsic…

Autistic children are less likely to be jointly engaged with a play partner than nonautistic children, negatively impacting social communication development. Promoting joint engagement during play can be an important target for educators of autistic students, but educator perceptions of autistic students may affect their interactions with…

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…

Girls, more than boys, experience a decrease in the severity of autism symptoms during childhood. It is unclear, however, which specific autistic behaviors change more for girls than for boys. Trajectories of autism symptoms were evaluated using the Autism Diagnostic Observation Schedule-calibrated severity scores (ADOS-CSS). Change in the…

Play and playfulness have a key role in children's development. Not enough is known about the playfulness of children with autism spectrum disorder (ASD) and its relationship to children's behavioural problems, as well as the role of caregiver behaviours during play in this relationship. The present study examines the moderating role of teachers'…

This study used a randomized controlled trial to compare two distinct models of group social skills interventions with adolescents with autism spectrum disorder (ASD). Participants had a confirmed diagnosis of ASD, had an IQ greater than or equal to 70, and were educated in the general education setting. Data from 62 adolescent participants who…

To date there are no evidence-based comprehensive interventions for use in school settings. There are numerous barriers to delivery of high-quality interventions in schools that have limited the transfer of research-based interventions to school settings. "Modular Approach to Autism Programing for Schools (MAAPS)" is a framework for…

Numerous research studies have been completed on the topic of Autism Spectrum Disorder (ASD). As individuals with this diagnosis are frequently treated by occupational therapists, this review will focus on research that has been completed on ASD that will provide insights into the understanding and treatment of children on the spectrum.

The high prevalence of Autism Spectrum Disorder (ASD) necessitates acquiring early detection tools that can lead to appropriate interventions for children and assist children in performing as many life functions as possible. In addition, early detection tools for ASD can realize quality early childhood development. This study aims to review…

The establishment of reciprocal friendships is a challenge for many individuals with autism spectrum disorder (ASD). Social interaction difficulties emerge early, persist throughout development, and have widespread functional impact. As such, interventions focused on social functioning are needed in early intervention programs. This two-part study…

Viewed through a social justice lens, preschool expulsion is an educational equity issue. This study focused on prior expulsion from preschool and child-care in a longitudinal study of 203 autistic children, ages 4 to 7. By parent report, 16%--one out of six autistic children--had been expelled from a preschool or child-care setting prior to…

Adolescents with autism spectrum disorder (ASD) often experience challenges with social skill interactions that may affect their quality of life. Given that parents are often the most frequent and constant presence in their child's life, parents serve a vital role in their child's social and behavioral development. For this reason, children may…

Racial differences in parent report of concerns about their child's development to healthcare providers may contribute to delayed autism spectrum disorder diagnoses in Black children. We tested the hypotheses that compared to White parents, Black parents of children with autism spectrum disorder would report fewer concerns about autism symptoms…

Siblings play an important role in shaping the developmental trajectories of individuals with autism spectrum disorder. Having siblings has been associated with better social communication, non-verbal communication, and theory of mind abilities in autism spectrum disorder. However, little is known about the impact of siblings on adaptive skill…
