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,…

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…

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…

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…

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…

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…

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…

The interactions between sleep problems, autism symptoms and emotional and behavioural difficulties were explored using network analysis in 240 autistic children (mean age: 8.8 years, range 5-13 years) with moderate to severe sleep problems. Findings revealed a highly connected and interpretable network, with three separate clusters identified of…

Autistic advocates emphasise the need for neurodiversity-affirming and strengths-based approaches to support services; however, little is known about broader community perspectives regarding the appropriateness of offering early support services to autistic children. This co-designed mixed-methods study employed surveys to gather insights from 253…

Sensory differences are well documented in autistic individuals. However, early sensory experiences have not been fully explored, particularly from the perspective of autistic people. We sought to understand early sensory experiences in autism from the perspective of autistic adults (some of whom also had autistic children) and caregivers of…

Research suggests that challenges associated with raising a child with an Autism Spectrum Disorder (ASD) can increase parents' risk for diminished parenting self-efficacy (PSE) and psychological wellbeing. The present study aimed to explore interrelationships between noteworthy predictors of PSE and parental psychological distress, including…

Using games as part of the intervention and support process (sometimes referred to as 'gaming therapy') is an increasingly popular method of supporting autistic youth to develop social competencies and other skills because they are believed to be inherently motivating and fun for youth. Some emerging research has indicated that intervention…
