Routinely collected data help estimate the prevalence of autism spectrum disorder (ASD) in jurisdictions without active autism surveillance. We created a population-based cohort of 1,211,834 children born in 2002-2015 in New South Wales, Australia using data linkage. Children with ASD were identified in three datasets -- disability services,…

There has been intense debate within the autistic and autism communities about the use of autism biobanks -- repositories containing biological and phenotypic materials -- and of genomic autism research more broadly. Here, we sought to understand the views and experiences of those contributing to one specific biobank, the Australian Autism…

Anecdotal reports link a distinct, bilateral, parieto-temporally generated 4.5-Hz rhythm on an electroencephalogram to a methylenetetrahydrofolate reductase gene variant co-occurring in autism spectrum disorder, but the validation of its precision is needed. The electroencephalograms of children with autism spectrum disorder showing the distinct…

Using a cross-sectional design, this study explored attachment insecurity and disorganization (assessed using the Strange Situation Procedure) in 90 toddlers (aged 14-24 months) with and without autism traits and assessed the associations between autism traits (severity and profiles) and both developmental level and attachment classification. Our…

Limited research exists on fathers' experiences of interparental conflict (IPC) in families with autistic children. We aimed to identify: (1) the extent to which these fathers report IPC across 10 years of child development (4-14 years) and how this compares to fathers of non-autistic children; (2) distinct trajectories of IPC for fathers of…

Obsessive-compulsive disorder (OCD) and autism are characterized by the presence of repetitive behaviors. Differentiating between repetitive behaviors attributable to a diagnosis of autism, and those attributable to OCD, poses challenges for differential and co-occurring diagnosis. Differentiation is important to inform appropriate supports and…

Disordered sleep is common in autistic children. This study aimed to evaluate the cost-effectiveness of a brief behavioural sleep intervention, the 'Sleeping Sound intervention', in primary school-aged autistic children in Australia. A cost-effectiveness analysis was undertaken alongside a randomised controlled trial over a 6-month follow-up…

The aim of this systematic review was to investigate what is currently known about autistic adults' participation in physical activity and sedentary behaviour and explore any associated correlates of these behaviours. The databases EMBASE, MEDLINE, PsycINFO, PubMed, and SPORTDiscus were searched for relevant literature. The review was registered…

Autism research is on the cusp of significant change. There are mounting calls from Autistic self-advocates, researchers, and other scientists for a paradigm shift in autism research. Yet little is known about what non-academic members of the Autistic and autism communities think about autism research. We -- a team of Autistic and non-autistic…

Autistic children are less likely to participate in sport than non-autistic children, but we know little about how patterns of participation in team and individual sport change across childhood. Drawing on a nationally representative cohort of Australian children, this study analysed trajectories of participation in team and individual sport…

Autistic people are at elevated risk of mental health conditions and experience significant barriers to effective support. While adaptations to therapy for autistic people have been proposed by clinicians, there is limited research on how helpful autistic people themselves rate these. We aimed to address this gap. Participants were 130 autistic…

Academic library literature contains several studies on the experience of autistic students navigating the world of higher education and its libraries. However, very little is published on the employment experiences of autistic academic librarians. This study attempts to examine employment barriers for autistic people currently or previously…

People on the autism spectrum can learn about autism from various sources, likely differing in the information, portrayal, and discussion they offer. The present study investigates where autistic people learn about autism, and whether their information source is associated with their level of autism knowledge, perceptions of stigma, and…

Purpose: Professional supports play an important role in aiding autistic children's learning, participation, and overall wellbeing. Yet, limited research exists on stakeholders' perspectives and preferences regarding targeted outcomes for children undergoing support facilitated by professionals. This study investigated stakeholder views on the…

Purpose: The PEDI-CAT (ASD) is used to assess functioning of children and youth on the autism spectrum; however, current psychometric evidence is limited. This study aimed to explore the reliability, validity and acceptability of the PEDI-CAT (ASD) using a large Australian sample. Methods: Caregivers of 134 children and youth on the spectrum…
