Characterizing the Nature of Alexithymia in Autistic Adults: Validation of the Perth Alexithymia Questionnaire

Alexithymia—a trait characterized by difficulties in emotion processing—is of high interest in the autism field. However, the lack of validated alexithymia measures for autistic individuals limits progress. This study aimed to address this gap by examining the psychometric properties of the Perth Alexithymia Questionnaire (PAQ) across autistic and non-autistic samples. Using the PAQ, we investigated how alexithymia manifests in autistic individuals and its links with poor mental health outcomes (anxiety).

“I Just Feel Like the Teacher Understood Me, and She Knew What I Needed”: School Experiences of Autistic Students from Diverse Backgrounds

Gathering Autistic young people's testimony is critical for understanding their lived experience of education and designing settings in which these students can thrive. Despite increasing knowledge in this field, we lack perspectives from a broad range of Autistic students which necessarily limits our ability to build inclusive, supportive environments for all. This study explored the educational experiences of preschool and school-aged Autistic students from diverse age groups, backgrounds, and educational settings.

Psychometric evaluation of the Comprehensive Autistic Trait Inventory in autistic and non-autistic adults

Measures of autistic traits are only useful – for pre-diagnostic screening, exploring individual differences, and gaining personal insight – if they efficiently and accurately assess autism as currently conceptualised while maintaining psychometric validity across different demographic groups. We recruited 1322 autistic and 1279 non-autistic adults who varied in autism status (non-autistic, diagnosed autistic, self-identifying autistic) and gender (cisgender men, cisgender women, gender diverse) to assess the psychometric properties of the Comprehensive Autistic Trait Inventory, a recently developed measure of autistic traits that examines six trait domains using 42 self-report statements.

Parsing the heterogeneity of social motivation in autism

Social motivation is posited as a key factor in the expression of the autism phenotype. However, lack of precision in both conceptualization and measurement has impeded a thorough understanding of its diverse presentation and associated outcomes. This study addresses this gap by identifying subgroups of autism characterized by deficits in distinct facets of social motivation, relative to normative benchmarks.

Autism Early Intervention Providers: Their Priorities, Use of Empirically Supported Practices, and Professional Development Needs

Autism early intervention research has indicated a research-to-practice gap, including continued use of practices with inadequate research support, and insufficient use of empirically supported practices. The present study explored the processes and mechanisms through which providers working with young children on the autism spectrum learn, select, and implement the various practices in their clinical repertoires. 

Multigenerational Familial and Environmental Risk for Autism (MINERvA) Network

The MINERvA Network will allow more accurate and precise determination of the contributions of familial and environmental factors to the etiology of autism.

Autism Research

The Kids' autism research takes place at CliniKids, a centre that integrates world-class research with a clinical service for children with developmental delay and/or autism and their families.

Early biomarkers predictive of autism

This study aims to investigate the cellular and molecular profiles of the immune system in infants at high/low risk for Autism, as determined through clinical assessment.

Plasma Metabolite Profiles of Children with Autism Spectrum Disorder

Autism spectrum disorder (ASD), a neurodevelopmental condition characterised by social and communication differences, is complex and aetiologically heterogeneous. Untargeted metabolomics is emerging as a tool in screening for biochemical abnormalities. This research was conducted using the Australian Autism Biobank resource and involved analysis of plasma metabolites to characterise metabolite differences between autistic children and controls.

Characterizing Transdiagnostic Processes Underlying the Drive to Socially Engage: A Multimeasurement Factor Analytic Investigation

Altered 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.
