Purpose: An official autism diagnosis is required to access timely intervention and is associated with better long-term wellbeing and mental health. Certain demographic characteristics, such as being female or a racially or ethnically minoritized youth, have been associated with significant diagnostic lag. However, it remains unclear how assigned…

This study examined whether autistic people with siblings score higher on measures of empathy than those without siblings. Cohorts of autistic children (n = 939; mean age = 7.35 years (SD = 2.15)) and autistic adults (n = 736; mean age = 37 years (SD = 12.39)) from the Cambridge Autism Research Database (CARD) were each divided into two groups:…

Intellectual disability in India is substantially under-reported, especially amongst females. This study quantifies the prevalence and gender bias in household reporting of intellectual disability by estimating the age-and-gender specific prevalence of the intellectually disabled by education, Socio-Demographic Index (SDI) score, place of…

This study explored the salient characteristics of transactions within parent-child engagement and investigated relationships between transactional characteristics and future identification of autism. The main aims of the study were to (1) examine if parents/children and their initial behaviors impact the length of transaction; (2) determine…

Although augmentative and alternative communication (AAC) strategies are often used by autistic youth, little is known about the use of AAC in inpatient psychiatric settings. This study evaluated how demographic and clinical factors (e.g., language level, IQ) related to AAC use in a well-characterized sample of 527 autistic youth (78.7% male, mean…

Alan H. Gerber; Jason W. Griffin; Cara M. Keifer; Matthew D. Lerner; James C. McPartland – Journal of Autism and Developmental Disorders, 2025
Purpose: Social anhedonia is a transdiagnostic trait that reflects reduced pleasure from social interaction. It has historically been associated with autism, however, very few studies have directly examined behavioral symptoms of social anhedonia in autistic youth. We investigated rates of social anhedonia in autistic compared to non-autistic…

Previous research links resting frontal gamma power to key developmental outcomes in young neurotypical (NT) children and infants at risk for language impairment. However, it remains unclear whether gamma power is specifically associated with language or with more general cognitive abilities among young children diagnosed with autism spectrum…

Krieger, Israel; Erez, Galit; Weinstein, Orly; Cohen, Arnon Dov; Tzur Bitan, Dana – Journal of Autism and Developmental Disorders, 2023
In this study we aimed to assess whether individuals with ASD are prone to higher infection rates, or to severe COVID-19 illness. Individuals with ASD and age- and gender-matched controlled counterparts (total n = 32,812) were assessed for COVID-19 infection rates and hospitalizations. Results indicated higher infection rates among individuals…

Autism Spectrum Disorders (ASD) prevalence has risen globally, with regional variation and sociodemographic disparities affecting diagnosis and intervention. This study examines ASD trends from 1990 to 2018 in California (CA), focusing on sociodemographic factors that may inform policy/interventions. Using CA Department of Public Health birth…

The purpose of this project was to investigate potential correlates of family life impairment in families of young autistic children. This project incorporated measures of specific child and parent challenges in addition to a commonly used unidimensional measure of autism characteristics. In this way, we could assess whether such challenges…

Miller, Haylie L.; Thomi, Morgan; Patterson, Rita M.; Nandy, Karabi – Journal of Autism and Developmental Disorders, 2023
Children with complex behavioral profiles (e.g., ASD + ADHD) may experience delays in obtaining a final diagnosis. Low-resource or underrepresented groups may be at even greater risk for delayed diagnosis. We assessed the effect of sociodemographic factors, symptom complexity and co-occurring conditions, and identifier of first symptoms on…

This study investigated sex and age differences in autistic behaviours in children with neurofibromatosis type 1 (NF1) who scored within the clinical range on the Social Responsiveness Scale - Second Edition (T score [greater than or equal to] 60). Thirty-four males and 28 females (3-16 years) were assessed with the Autism Diagnostic Observation…

Background: Sensory processing differences are reported both in children with ADHD and in children with autism. Given the substantial overlap between autism and ADHD, the current study examined which sensory features were uniquely predictive of autistic traits after controlling for ADHD symptoms, age, IQ, and sex in a sample of children and…

Fixel-based analysis was used to probe age-related changes in white matter micro- and macrostructure of the corpus callosum between participants with (N = 54) and without (N = 50) autism spectrum disorder (ASD). Data were obtained from the Autism Brain Imaging Data Exchange-II (ABIDE-II). Compared to age-matched controls, young adolescents with…

Kavanaugh, Brian C.; Schremp, Christine A.; Jones, Richard N.; Best, Carrie R.; Sheinkopf, Stephen J.; Morrow, Eric M. – Journal of Autism and Developmental Disorders, 2023
The objective of this study was to determine the clinical features that moderate a later age at ASD diagnosis in females in a large sample of females with ASD. Within two large and independent ASD datasets (>20,000 females), females were first diagnosed with ASD 14-months later relative to males. This later age at diagnosis was moderated by a…
