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.

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.

Critical Appraisal of Systematic Reviews Assessing Gut Microbiota and Effect of Probiotic Supplementation in Children with ASD—An Umbrella Review

Given 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. 

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.

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.

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.

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.

Low-intensity parent- and clinician-delivered support for young autistic children in Aotearoa New Zealand: a randomised controlled trial

Aotearoa New Zealand does not provide publicly-funded intensive autism support. While parent-mediated supports are promising, children and families may also benefit from direct clinician support. We tested the efficacy of a low-intensity programme involving parent- and clinician-delivered support for autistic children.

The use of psychotropic medications in autistic individuals (21 years and younger) in Western Australia: A preliminary investigation

Prescriptions and use of medications to treat mental health conditions in young autistic populations are inconsistent worldwide. This makes it hard to compare findings from international studies to the Australian autistic population, where there are limited relevant studies. Apart from risperidone, there are no other medications specified for direct use in autistic persons. This study aims to gain initial broad understanding of the use of medications, commonly prescribed for mental health conditions, specifically by autistics under the age of 21 years.
