Oxidative stress has been proposed as being important in the pathophysiology of autism spectrum disorders (ASD), and heightened levels of oxidative stress has found in children with ASD. Our aim was to investigate, whether this change is temporary or persist into adulthood. We included 89 adult patients with ASD and sex and age matched controls.…

Autism and anxiety are thought to be related to extreme demand avoidance (EDA), which is characterised by intense avoidance of everyday demands. However, the relative importance of autism and anxiety to EDA has yet to be investigated, and little is known about EDA in adulthood. We conducted two online survey studies (Ns = 267 and 549) with adults…

The present study investigated the relation between autistic traits and gender minority stress and the relative importance of autistic traits and gender minority stress in predicting mental health outcomes in gender minority adults. An online survey was completed by 90 transgender women, 72 transgender men, 48 non-binary individuals assigned male…

To date, studies have not established whether autistic and non-autistic individuals differ in emotion recognition from facial motion cues when matched in terms of alexithymia. Here, autistic and non-autistic adults (N = 60) matched on age, gender, non-verbal reasoning ability and alexithymia, completed an emotion recognition task, which employed…

Self-compassion is a gentle way of relating to oneself, linked to a host of mental health benefits in non-autistic people. Although many autistic individuals report high anxiety and depression symptoms, no research to-date has examined the self-compassion experiences of autistic individuals and determined if self-compassion is associated with…

Carers of adults on the autism spectrum often experience high levels of stress, worry, and caregiver burden. There are few studies identifying the predictors of carer mental well-being and none have been conducted in Australia. Data from the Autism Cooperative Research Centre for Living with Autism's Australian Longitudinal Study of Autism in…

Longitudinal studies have generally reported poor outcomes in adulthood for the majority of individuals (c.50-60%) with autism. Several factors putatively predict outcome (e.g. IQ), but findings remain mixed. This paper presents an updated meta-analysis of autism outcome studies and extends previous findings with additional analyses (including…

Prosody or "melody in speech" in autism spectrum disorder (ASD) is often perceived as atypical. This study examined perception and production of statements and questions in 84 children, adolescents and adults with and without ASD, as well as participants' pitch direction discrimination thresholds. The results suggested that the abilities…

The aim of this study was to identify emotion regulation (ER) strategies that most strongly impact momentary mood in a sample of 23 adults with and 19 without autism spectrum disorder (ASD). Participants completed cognitive and behavioural assessments, online questionnaires, and experience sampling methodology questions. In the ASD group, the use…

Self-harm is purportedly common in autistic individuals, but under-researched, particularly in younger samples and those "without" intellectual disability. This study aimed to describe prevalence, profile and correlates of self-harm in autistic individuals without impairments in adaptive functioning. Parents of autistic participants (n =…

Gaming disorder (GD) is a clinical addiction to video or internet games. This study investigated whether GD symptoms are heightened in adults with autism spectrum disorder (ASD) in comparison to a control group, and explored predictors of GD in 230 adults with ASD and 272 controls. The relationship between GD and gelotophobia was examined.…

A geographic information system (GIS) approach systematically assessed whether population density and distribution of community resources contributed to caregiver reported community participation outcomes for 124 adults with autism spectrum disorder (ASD). Regression analyses examined whether GIS measures predicted community participation in areas…

Suicidality is significantly more common in autistic adults than the general population, yet the factors that increase risk for suicidality among autistic adults remain largely unknown. We identified characteristics associated with suicidal ideation and suicide attempts/self-inflicted injury in a U.S. national sample of Medicare-enrolled autistic…

With the increasing prevalence of adults with autism spectrum disorder (ASD), research examining the service experiences of this population is greatly needed. The current study investigated service use, unmet needs, and obstacles to service access for a large sample of adults with ASD. After accounting for various demographic factors known to…

People with autism spectrum disorder (ASD) have an increased risk of suicidality. However, the risk factors remain under-investigated. This study explored factors that increase suicidality risk in ASD. Through an online survey, 150 adults with ASD were compared to 189 control adults. Autistic traits, depressive symptomatology, alexithymia, and…
