Intellectual disability and autism prevalence in Western Australia: impact of the NDISEstimates of the prevalence of intellectual disability or autism spectrum disorder may vary depending on the methodology, geographical location, and sources of ascertainment. The National Disability Insurance Scheme in Australia was introduced progressively from 2016 to provide individualized funding for eligible people with a significant and permanent disability.

‘It depends entirely on the nature of those supports’: Community perceptions of the appropriateness of early support services for autistic childrenWe do not know much about what support services people think are okay for young autistic children. This study was a survey of 253 people. We asked autistic adults, parents, and professionals from Australia and New Zealand whether they thought it was okay to provide support services to autistic children.

Absence of association between maternal adverse events and long-term gut microbiome outcomes in the Australian autism biobankMaternal immune activation and prenatal maternal stress are well-studied risk factors for psychiatric conditions such as autism and schizophrenia. Animal studies have proposed the gut microbiome as a mechanism underlying this association and have found that risk factor-related gut microbiome alterations persist in the adult offspring.

Critical Appraisal of Systematic Reviews Assessing Gut Microbiota and Effect of Probiotic Supplementation in Children with ASD—An Umbrella ReviewGiven the significance of gut microbiota in autism spectrum disorder (ASD), we aimed to assess the quality of systematic reviews (SRs) of studies assessing gut microbiota and effects of probiotic supplementation in children with ASD. PubMed, EMBASE, PsycINFO, Medline, and Cochrane databases were searched from inception to November 2024.

Caregiver perspectives regarding the impact of feeding difficulties on mealtime participation for primary school-aged autistic children and their familiesAlthough up to 89% of autistic children experience feeding difficulties, little is known about the impact of these difficulties on mealtime participation. The aim of this study was to explore the impact of feeding difficulties on the mealtime participation of autistic children and their families based on caregiver experiences.

Characterizing Transdiagnostic Processes Underlying the Drive to Socially Engage: A Multimeasurement Factor Analytic InvestigationAltered drive to socially engage is a transdiagnostic feature across multiple psychopathologies. Yet, lack of clarity regarding specific processes that constitute social drive, along with insufficient measurement methods, has hindered understanding in this area. This study ascertained the feasibility of approximating difficulties within specific fine-grained social drive processes as proposed by 2 theoretical frameworks: “orienting,” “wanting,” “pursuing,” “liking,” “learning,” and “reticence” within a reward processing framework and “orienting,” “seeking and maintaining,” and “liking” within a social motivation framework.

The Comprehensive Autistic Trait Inventory (CATI): development and validation of a new measure of autistic traits in the general populationTraits and characteristics qualitatively similar to those seen in diagnosed autism spectrum disorder can be found to varying degrees in the general population. To measure these traits and facilitate their use in autism research, several questionnaires have been developed that provide broad measures of autistic traits [e.g. Autism-Spectrum Quotient (AQ), Broad Autism Phenotype Questionnaire (BAPQ)]. However, since their development, our understanding of autism has grown considerably, and it is arguable that existing measures do not provide an ideal representation of the trait dimensions currently associated with autism. Our aim was to create a new measure of autistic traits that reflects our current understanding of autism, the Comprehensive Autism Trait Inventory (CATI).

Optimal interpregnancy interval in autism spectrum disorder: A multi-national study of a modifiable risk factorIt is biologically plausible that risk of autism spectrum disorder (ASD) is elevated by both short and long interpregnancy intervals (IPI). We conducted a retrospective cohort study of singleton, non-nulliparous live births.

An evidence-based framework for determining the optimal amount of intervention for autistic childrenThe provision of timely, effective, and socially valid non-pharmacological intervention is at the core of efforts to support the development of young autistic children. These efforts are intended to support children to develop skills, empower their caregivers, and lay the foundation for optimal choice, independence, and quality of life into adulthood.

A Survey of Autistic Adults from New Zealand on the Autism Diagnostic Process During Adolescence and AdulthoodThe diagnostic experiences of autistic adults in New Zealand have not been investigated and little is known globally about autistic adults' satisfaction with the autism diagnostic process. This study describes the diagnostic experiences of 70 autistic adults living in New Zealand and explores how these experiences are related to satisfaction during three stages of the diagnostic process. The results show that autistic adults were reasonably satisfied with the early query and diagnostic assessment stages, but were dissatisfied with the post-diagnostic support stage, with significant unmet needs. Dissatisfaction during the post-diagnostic support stage was also related to satisfaction during previous stages and poor coordination of supports. Suggestions are made on how to improve the autism diagnostic pathway for autistic adults in New Zealand.
