The association between maternal diabetes and risk of autism spectrum disorder in offspring was not completely consistent. We performed an updated and systematic review and meta-analysis with relevant studies published until 6 August 2020. We included 17 publications, describing 15 studies, including 1,751,537 participants. Exposure to maternal…

Background: Individuals with intellectual disability or autism exhibit suicidal behaviours at an equal or greater rate than the general population, yet little is known about associated risk factors. This study explores suicidality in these populations, focusing on their understanding of suicide and death and perceptions of their direct support…

Targeted screening of children at increased likelihood of autism is recommended. However, autism screening tools are usually validated for use mainly in low-likelihood populations. This study compared the accuracy of the Modified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F), the ASDetect app, and the Social Attention and…

Purpose: Access to research programs and increased diversity in research enrollment may be key to improving diverse populations' health and healthcare outcomes. To facilitate research recruitment, a Research Registry ("Registry"), a pre-recruitment database, was developed at an urban tertiary Autism Center ("Autism Center"). In…

Previous researchers have demonstrated that using stimuli identified via daily brief preference assessments may produce more responding under concurrent-schedule arrangements than using stimuli identified via lengthy, pre-treatment preference assessments (DeLeon et al., 2001). To date, this has not been evaluated within the context of skill…

Gelotophobia (fear of being laughed at) is an under-researched phenomenon in autistic people, yet can have a significant impact on autistic people's quality of life. A narrative review was undertaken to explore if gelotophobia and being autistic are related and what is currently known in the academic literature regarding gelotophilia (joy of being…

There is a higher incidence of diagnosed Autism Spectrum Disorder (ASD) in children with visual impairment and blindness (VIB) than in typically sighted children. However, we currently lack appropriate assessment measures to fully understand the neurodevelopment of children with VIB. Numerous factors, such as common characteristics between…

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)…
