Motor stereotypy is a type of repetitive motor behavior frequently occurring in autism spectrum disorder (ASD). Individuals with maladaptive daydreaming (MD) report repetitive motor behavior associated with addictive and immersive daydreaming. Many autistic self-advocates report symptoms of MD. Motor stereotypy in ASD is associated with lower…

The Anxiety Scale for Autism--Adults (ASA-A) captures the autistic anxiety experience, but we do not know whether it is structurally equivalent for men and women, or non-autistic people. Measurement invariance analysis considered gender and diagnostic status (342 cis-gender autistic men (N = 105) and women (N = 237), 316 cis-gender non-autistic…

The Language ENvironment Analysis (LENA) system has been used increasingly in research to record and evaluate the everyday speech of autistic children and their families. However, it is unclear how researchers are using LENA and whether the system is well-suited for work with autistic individuals. The purpose of this systematic review is to…

Difficulties regulating emotions have been coined as inherent to autism, possibly even presenting a core difficulty of autism. While several models of emotion regulation have been proposed in the past, in this targeted review article, we aim to map emotion regulation difficulties in autistic individuals within the framework of the extended process…

Background: Mental health difficulties are common for autistic people; however, almost no interventions have been co-designed with the autistic community. Co-design has the potential to add important insights from lived experience into intervention design, but there are currently limited examples of how rigorously to undertake this practice. This…

Purpose: Predictions are complex, multisensory, and dynamic processes involving real-time adjustments based on environmental inputs. Disruptions to prediction abilities have been proposed to underlie characteristics associated with autism. While there is substantial empirical literature related to prediction, the field lacks a self-assessment…

Manifestations of insistence on sameness (IS) and circumscribed interests (CI) are complex, with individuals varying considerably, not only in the types of behaviours they express, but also in terms of a behaviour's frequency, intensity, trajectory, adaptive benefits, and impacts. However, current quantitative RRB instruments capture only certain…

Increasing research suggests a link between autism spectrum disorders and joint hypermobility, hypermobility spectrum disorders, and Ehlers-Danlos syndromes. However, no study systematically examined the available literature about the relationship between these conditions. A systematic literature search was conducted to identify studies (a)…

Objective: To evaluate the quality, understandability, actionability and readability of English-language Internet-based resources about autism spectrum disorder. Design: Cross-sectional observational study evaluating the quality, accountability, understandability, actionability and readability of English-language Internet-based resources related…

Neuroinflammatory mechanisms have been implicated in the pathophysiology of autism spectrum disorder (ASD). Minocycline is a matrix metalloproteinase inhibitor 9 (MMP9) inhibitor tetracycline antibiotic with known anti-inflammatory properties. In preclinical animal models of ASD, minocycline has demonstrated potential positive effects on…

Purpose: Autistic adults consistently report difficulties understanding speech in adverse listening environments, which may be related to differences in social communication and participation. Research examining masked-speech recognition in autistic adults is limited, particularly in competing speech backgrounds with high degrees of informational…

Autism spectrum disorders are potentially associated with gastrointestinal dysfunction, although the underlying mechanisms remain unclear. Recently, the oral cavity has gained attention as the starting point of the digestive tract. We aim to explore the potential association between altered oral microbiota and oxidative stress in individuals with…

Autism spectrum disorder requires a careful approach from professionals and a favorable clinical environment for dental care and assistance. This article aims To perform a literature review about oral health among people with autism spectrum disorder and dental management strategies for this group. An integrative literature review was carried out…

Introduction: The challenges experienced by adults living with autism spectrum disorder (ASD) regarding their interaction with their home environment are thinly documented, although these issues persist with age. Based on the Model of Competence, this study aims to explore the human and nonhuman elements of the home environment influencing the…

Routinely collected data help estimate the prevalence of autism spectrum disorder (ASD) in jurisdictions without active autism surveillance. We created a population-based cohort of 1,211,834 children born in 2002-2015 in New South Wales, Australia using data linkage. Children with ASD were identified in three datasets -- disability services,…
