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…

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…

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…

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…

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…

Background: Although autism is commonly described in terms of deficits, many autistic individuals have been found to demonstrate exceptional skills. The shift to a strengths-based approach in the field of autism necessitates increased understanding of these skills. Aims: This study examined (1) rates of exceptional skills in autistic school-age…

This study examined whether parent-reported atypical development in their child's first year was associated with age of diagnosis and age when parents first needed to consult a specialist about their child's development. It involved 423 children who participated in the Australian Autism Biobank. Most parents retrospectively identified [greater or…

Purpose: Parenting has implications for psychosocial adjustment well into adulthood. While much is known about the parenting behaviors that influence adjustment in autistic children, little is known about how the effects of parenting persist in autistic adults. Further, autistic adults' perspectives on how they were parented have not been…

Many autistic adults are likely to experience poor financial wellbeing and hardship due to unemployment and under-employment. Research in the general population demonstrates that subjective financial wellbeing--how people perceive their financial situation--influences quality of life. There is no research, however, examining the subjective…

Communication and interaction in neurotypical environments can be challenging for autistic individuals, potentially disrupting the parent-child relationship. In Relationship Development Intervention (RDI) that facilitates improved interactions between autistic children and their parents, RDI Consultants play key roles in enabling parents to…

There is a significant variability in the prevalence of psychotropic medication use among young autistic persons worldwide and this is under-studied in Australia. Apart from risperidone, approved by the Therapeutic Goods Administration to manage challenging behaviour, the appropriateness of other psychotropic medications prescribed to young…

Purpose: Caring for an autistic child is associated with elevated stress, anxiety and depression. Although some data suggest that 'child' or 'carer' factors may moderate the severity of carer distress, relatively few international comparisons have been made, limiting the generalizability of previous findings. This study aimed to address this…
