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).

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.

Evaluating placebo responses to intranasal oxytocin in autism: findings from the placebo lead-in phase of a randomised controlled trial

The placebo effect is established in clinical trials, but for paediatric research, questions remain about how to best manage its influence. Within the autism field, data on these issues is sparse. This is particularly important in the oxytocin field where placebo responses are thought to play an important role. This study reports on data from the single-blind, placebo lead-in phase of a randomised controlled trial to investigate the placebo response and its relationship to treatment response in autistic children. 

Child and Family Characteristics as Predictors of the Severity of Self-injurious Behaviours in Autistic Children and Adolescents

Autistic children demonstrate an increased likelihood of self-injurious behaviours (SIB). To support autistic individuals who exhibit SIB and understand the factors that contribute to SIB, we examined several child and family characteristics associated with the severity of SIB.

Community perspectives on the appropriateness and importance of support goals for young autistic children

Researchers do not know much about what autistic adults, parents and professionals think about support goals for young autistic children. People's views of support goals might also be influenced by their beliefs about early support more generally. This survey involved 87 autistic adults, 159 parents of autistic children and 80 clinical professionals living in New Zealand and Australia.

Investigating the impact of autistic children's feeding difficulties on caregivers

The aim of this study was to investigate the influence of children's autism characteristics, sensory profiles and feeding difficulties on caregiver-reported impact at mealtimes.

Absence of association between maternal adverse events and long-term gut microbiome outcomes in the Australian autism biobank

Maternal 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.

Empathy and Autism: Establishing the Structure and Different Manifestations of Empathy in Autistic Individuals Using the Perth Empathy Scale

There is a common mischaracterisation that autistic individuals have reduced or absent empathy. Measurement issues may have influenced existing findings on the relationships between autism and empathy, and the structure of the empathy construct in autism remains unclear.

Parent-reported Areas of Greatest Challenge for their ADHD and/or Autistic Children

This study aimed to understand how parents describe the most challenging behaviors exhibited by their children diagnosed with autism and/or ADHD, how those behaviours impact their family, and whether challenges are directly related to the core characteristics of these conditions. 

Predictors of Change in Wellbeing and Mental Health of Parents of Autistic Pre-Schoolers

Parenting is a rewarding experience but is not without its challenges. Parents of Autistic children face additional challenges, and as a result can experience lower levels of wellbeing and more mental health problems (i.e., depression, anxiety, stress). Previous studies have identified concurrent correlates of wellbeing and mental health.
