Recent research has suggested that people with autism spectrum disorder may be disproportionately at risk of substance use disorders. This study analyzed national-level Medicaid Claims data to compare substance use disorder prevalence among Medicaid enrollees with autism spectrum disorder (N = 388,426) and a random sample of enrollees without…

Play, in particular sex-typical play, is important for affective, cognitive, and social development. There is limited research on sex-typical play in autistic children. The few prior studies on this topic relied heavily on reports or involvement of caregivers/parents, did not assess cognitive abilities, and examined a limited number of sex-typical…

The capacity of the workforce lags behind the current demand for timely autism diagnostic assessment. Primary care providers (PCPs) are well-positioned to diagnose autism at earlier ages than providers from other disciplines. Thus, bolstering PCPs' diagnostic capabilities has been the focus of many recent capacity-building initiatives. Using data…

Despite very high rates of suicidal thoughts and behaviors (STB) in autistic adults, the key psychosocial drivers of this phenomenon remain unknown. To investigate, we examined how lifetime stressor exposure and severity, which have been found to predict STB in non-autistic populations, related to STB in a multinational dataset of 226 autistic…

Special education services are crucial for enhancing outcomes and well-being among autistic students. Unfortunately, many racially and ethnically minoritized and girl autistic youth face challenges in timely and accurate identification. National-level data reveal autism prevalence rates differ across student gender, race, and ethnicity hindering…

Racial/ethnic minoritized youth are underrepresented in autism research. Documented inequities in accessibility to and utilization of autism-specific services highlight the importance of better understanding for whom and under what conditions autism evidence-based practices (EBPs) work. This report examines the race, ethnicity, sex, and gender of…

Several validated adult autism symptom screening tools exist; however, there are concerns about the validity of instruments in adults who self-identify and those who have an autism diagnosis. This study evaluated the psychometric properties of the RAADS-R and RAADS-14 across gender, autism diagnosis and autistic identity, and age among a sample of…

Autism research tends to exclude racially and ethnically minoritized autistic individuals, limiting the quality of the evidence base for characterizing and diagnosing language impairment in racially and ethnically minoritized autistic individuals. This systematic review examines reporting practices for participant socio-demographics in studies…

Camouflaging is hypothesized to play an important role in developing mental health difficulties. But this might not be true for everyone. It remains unclear for whom camouflaging is associated with mental health. In this preregistered study (AsPredicted #45095), we investigated whether (1) camouflaging and mental health were associated and (2) we…

Supporting more autistic people into employment is a major priority of the United Kingdom's National Autism Strategy (2021-2026). However, little is known about the barriers employers perceive to hiring autistic people. A pre-registered cross-sectional survey study was conducted on a nationally representative sample of 1212 individuals with recent…

Studies have shown that there are differences between the presentations of males and females diagnosed with autism. There remains a developing understanding about how the presentation of autism differs between boys (hereafter referred to as 'assigned males at birth') and girls (assigned females at birth). This study sought to investigate the…

Little is currently known about the autism spectrum disorder (ASD)-related difficulties of females narrowly below the ASD diagnostic threshold and whether the disorder conceptualisation should be broadened to capture their presentations. We extracted fine-grained information from the assessment reports of 222 children who were either diagnosed…

Evidence suggests increased mortality rates among autistic individuals. However, risks of mortality, including natural-cause, suicide, and accident mortalities, among autistic individuals remain unclear. Among the entire Taiwanese population (N = 29,253,529), between 2003 and 2017, 45,398 autistic individuals were identified and 1:4 matched to…

Genetic tests, such as Fragile X and Chromosomal Microarray, are recommended as a standard of care during the evaluation of autism spectrum disorder (ASD) and other neurodevelopmental disorders. However, previous research demonstrates low rates of genetic testing. This study aimed to identify the rates of genetic testing and patient demographic…

There are fewer females than males diagnosed with autism, but autistic females are said to be under-identified and underrepresented in the existing diagnostic and service systems. The gender discrepancy may potentially be attributed to the lack of accurate understanding of autistic females and their needs. Emerging research has begun to document…
