Renowned Autism Researcher named Western Australian of the Year

Autism researcher Professor Andrew Whitehouse has been named this year’s Western Australian of the Year in the HBF Professions category.

Evidence that infant and early childhood developmental impairments are associated with hallucinatory experiences: Results from a large, population-based cohort study

Cognitive and motor dysfunction are hallmark features of the psychosis continuum, and have been detected during late childhood and adolescence in youth who report psychotic experiences (PE). However, previous investigations have not explored infancy and early childhood development.

Repetitive transcranial magnetic stimulation (rTMS) in autism spectrum disorder: Protocol for a multicentre randomised controlled clinical trial

There are no well-established biomedical treatments for the core symptoms of autism spectrum disorder (ASD). A small number of studies suggest that repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation technique, may improve clinical and cognitive outcomes in ASD.

Co-occurring intellectual disability and autism: Associations with stress, coping, time use, and quality of life in caregivers

Having a child on the autism spectrum (AS) is known to impact caregiver quality of life (QoL), time use, and stress. A co-occurring diagnosis of intellectual disability (ID) is common among children on the autism spectrum, with ID itself impacting caregiver outcomes. This study sought to understand how co-occurring ID in children on the autism spectrum may influence caregiver-related outcomes. Secondary analysis of survey data from caregivers of 278 children on the autism spectrum with (n = 62) and without (n = 216) co-occurring ID was conducted, exploring impacts on caregiver QoL, stress, coping, and time-use.

An investigation of adherence to best practice guidelines for autism diagnosis in New Zealand

Many clinicians in New Zealand do not follow guidelines for best practice in autism diagnosis. In this study, we investigated the processes that health professionals in New Zealand follow when diagnosing autistic children and adults. We asked 117 health professionals from a range of services and regions in New Zealand, how they identify and diagnose autism.

The Comprehensive Autistic Trait Inventory (CATI): development and validation of a new measure of autistic traits in the general population

Traits 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).

The associations between autistic and communication traits in parents and developmental outcomes in children at familial risk of autism at 6 and 24 months of age

Several studies have explored relationships between parent broader autism phenotype and offspring communication, and have reported that autistic-like traits in parents are related to offspring communication difficulties and autism severity. However, past research has focused on studying such associations in childhood and we know very little about them in infancy. With accumulating evidence that interventions administered during infancy may be most effective in reducing ASD symptoms, it is imperative to examine whether relationships between parent autistic-like traits and child communication appear even earlier during this critical period of life.

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.

Measuring cognitive and affective empathy across positive and negative emotions: psychometric properties and measurement invariance of the Perth Empathy Scale

Empathy, a complex and multidimensional construct essential for social functioning and mental health, has been extensively studied in both research and clinical settings. The Perth Empathy Scale (PES), a recently developed self-report measure, assesses cognitive and affective empathy across both positive and negative emotions and is based on the self-other model of empathy. This study aimed to evaluate the psychometric properties of the Persian version of the PES in large Iranian sample.

Caregiver perspectives regarding the impact of feeding difficulties on mealtime participation for primary school-aged autistic children and their families

Although 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.
