Anecdotal reports link a distinct, bilateral, parieto-temporally generated 4.5-Hz rhythm on an electroencephalogram to a methylenetetrahydrofolate reductase gene variant co-occurring in autism spectrum disorder, but the validation of its precision is needed. The electroencephalograms of children with autism spectrum disorder showing the distinct…

This study examined the feasibility of implementing the Screening Tool for Autism in Toddlers, an interactive Level-2 screen for autism spectrum disorder, within Part C Early Intervention settings. Participants included 69 Early Intervention providers (M age = 43.3 years, 93.7% females, 92.4% Whites) from nine programs who attended a one-day…

Play is often included in autism diagnostic assessments. These tend to focus on 'deficits' and non-autistic interpretation of observable behaviours. In contrast, a neurodiversity-affirmative assessment approach involves centring autistic perspectives and focusing on strengths, differences and needs. Accordingly, this study was designed to focus on…

Clinician and caregiver reports of autism features are both integral to receiving an autism diagnosis and appropriate intervention, yet informant discrepancies are present in clinical practice and may differ by demographic characteristics of the child and family. The present study examined how clinician-caregiver discrepancies in ratings of a…

Autism is a neurodevelopmental condition, characterized by altered social communication and repetitive behavior. Typically diagnosed in early childhood, screening and diagnosis at a later age can be challenging, particularly in girls who exhibit a wider range of behaviors and characteristics. This study aimed to examine the Childhood Autism…

Autism spectrum disorder shares many symptoms with other mental health disorders, and comorbid disorders such as mood and anxiety disorders are common, making the diagnostic process challenging. We aimed to explore the diagnostic accuracy of two standard autism spectrum disorder diagnostic instruments and to identify those behavioral items that…

In autistic adults, measurement tools may not adequately differentiate between autistic characteristics and features of anxiety. This may be particularly evident in the case of social anxiety disorder; however, few measures of social anxiety disorder have been validated for autistic adults. Instead, assessments are often made using measures…

Autism spectrum disorder presents as a multifaceted condition characterized by pronounced impairments in social communication and behavioral patterns. Diagnosis hinges upon the expertise of clinicians, comprehensive developmental history, and observation of specific behavioral markers. However, in low-income countries, access to screening tools…

The Autism-Spectrum Quotient is a self-report scale, used to assess autistic traits. It was tested cross-culturally, and a short version was created to clinically refer adults for an autism assessment. This study aimed to examine the properties of the Hebrew version of the Autism-Spectrum Quotient and to create a short version suitable for…

Despite emerging awareness of gender diversity in the autistic population, our understanding of autism remains limited to cisgender boys and men. We conducted a scoping review to better understand how structural language skills (i.e. syntax, semantics, narrative) differ across sex/gender within autism, and how gender diversity is incorporated in…

The broad autism phenotype is the phenotypic expression of the primary characteristics of autism. However, currently available tests do not agree with the two-domain operationalization of broad autism phenotype or autism, and their internal structure has shown instability across applications. This study presents the Broad Autism…

Clinical judgement is a crucial part of autism and attention deficit hyperactivity disorder (ADHD) assessments. This study aims to harness insights from psychology and sociology to explore clinical perspectives and assessment practices of autism and attention deficit hyperactivity disorder. Qualitative interviews were conducted with health care…

To address the variability of naturalistic developmental behavioral intervention outcomes, the current study sought to isolate the effects of the instructional strategies of caregiver-mediated naturalistic developmental behavioral interventions. In this comparative efficacy trial, mothers of 111 autistic children (18-48 months) were randomized to…

Autism spectrum disorder is a neurodevelopmental disorder in which genetic factors play key roles. Limited research has been conducted on genetic testing of children with autism spectrum disorder in low middle-income countries. This prospective cross-sectional study was conducted at the pediatric neurology clinics of three university hospitals in…

Individuals diagnosed with autism spectrum disorder (ASD) are more likely to have suicidal thoughts and behaviors. However, little research delineates the temporal and mechanistic associations between potential risk factors and suicidality in autistic individuals. We assessed 129 autistic and 121 age-matched and sex-assigned-at-birth-matched…
