ASD symptoms in toddlers and preschoolers: An examination of sex differences / Rosmary ROS-DEMARIZE in Autism Research, 13-1 (January 2020)  

Public ISBD [article]  inAutism Research > 13-1 (January 2020) . - p.157-166 Titre : ASD symptoms in toddlers and preschoolers: An examination of sex differences Type de document : Texte imprimé et/ou numérique Auteurs : Rosmary ROS-DEMARIZE, Auteur ; Catherine BRADLEY, Auteur ; Stephen M.

CARPENTER, Auteur Article en page(s) : p.157-166 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  restricted repetitive behaviors  screening measures  sex differences  social communication deficits Index. décimale : PER Périodiques Résumé : Although considerable work has documented higher prevalence rates of autism spectrum disorder (ASD) in boys, fewer studies have focused on sex differences within samples of young children at-risk for ASD. This study examined sex differences in ASD symptom domains and ASD screening outcomes among toddlers (18-35 months) and preschoolers (36-72 months) with ASD-related concerns. Participants included 480 children between 18 and 72 months evaluated by university-based ASD specialty clinics. Results revealed significant sex differences in severity of social communication (SC) deficits across age groups. Within the toddler group, girls diagnosed with ASD displayed greater SC deficits according to standardized observation and clinician severity ratings. Within the preschool group, girls diagnosed with ASD were rated by parents as having more severe SC deficits, but these differences were not corroborated by standardized observations or clinician ratings. No sex differences emerged for severity of restricted repetitive behaviors (RRBs) for either age group. Across the entire referred sample, boys and girls did not differ in terms of scores on commonly used screening instruments. Importantly, results suggest that two of the most commonly used ASD screeners (i.e., Modified-Checklist for Autism in Toddlers-Revised with Follow-up and Social Communication Questionnaire ) may underidentify RRBs in toddler and preschool-aged girls as screening scores were only influenced by severity of SC deficits. Greater SC deficits in young girls with ASD along with its impact on screening status suggests greater attention be placed on the under-identification of ASD in girls as well as current screening measures' ability to tap into the topography of ASD symptoms across genders. Autism Res 2020, 13: 157-166. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: In this study, we found that young girls diagnosed with autism spectrum disorder tend to have greater social communication deficits than young boys and that these differences vary by age. Specifically, toddler-aged girls receive higher clinician ratings of social communication deficits when compared to boys, while preschool-aged girls receive higher parent ratings of social communication deficits. For girls, current screening tools seem to be more highly influenced by severity of social communication deficits than by restricted repetitive behaviors.

Comparative Analysis of Autistic Women Across the Lifespan: Childhood vs. Adulthood Diagnosis / Maire Claire DIEMER in Autism Research, 18-8 (August 2025)  

Public ISBD [article]  inAutism Research > 18-8 (August 2025) . - p.1651-1663 Titre : Comparative Analysis of Autistic Women Across the Lifespan: Childhood vs. Adulthood Diagnosis Type de document : Texte imprimé et/ou numérique Auteurs : Maire Claire DIEMER, Auteur ; Rosmary ROS-DEMARIZE, Auteur ; Catherine C.

CARPENTER, Auteur Article en page(s) : p.1651-1663 Langues : Anglais (eng) Mots-clés : adults  autism  co-occurring conditions  LGBT  lifespan  SPARK  women Index. décimale : PER Périodiques Résumé : ABSTRACT This study investigates the experiences of autistic adult women, a group understudied in autism research due to a predominant focus on early identification/intervention, restrictive research participation criteria, and differing rates of diagnosis by sex. This study characterizes a cohort of autistic adult women (n?=?1424) across various dimensions including demographics, relationships, education, employment, income, well-being, and co-occurring psychiatric conditions. It also explores differences among those diagnosed with autism as children versus those diagnosed as adults. The sample was limited to women able to read and provide independent consent to participate. Results indicated that the average age of diagnosis for those diagnosed before age 18 was 9.6?years old, whereas for those diagnosed in adulthood it was 31.8. Over 80% of the sample had completed some college or post-secondary education, with more than a third of those diagnosed as adults having attained a 4-year college degree or higher. More than half were employed, with those diagnosed as adults more likely to be employed full time (31.74%). Additionally, more than half were married or identified a romantic partner. Significant rates of psychiatric comorbidity were reported, with those diagnosed with autism as adults more likely to have co-occurring anxiety (69.87%), depression (61.79%), eating disorders (17.28%), and substance use diagnoses (8.85%) than those diagnosed as children. High rates of suicidal ideation (34%) and self-harm (21%) were endorsed in the full sample. Regression analyses indicated that being diagnosed with autism at a later age was associated with higher internalizing, externalizing, and substance use as well as a lower report of personal strengths, even when accounting for demographic factors. Despite these challenges, our findings highlight that many autistic women have positive outcomes and meet common adult developmental milestones. The authors advocate for the development of more tailored treatment options that address the specific needs of autistic women.

Profiles of nonverbal skills used by young pre-verbal children with autism on the ADOS-2: Relation to screening disposition and outcomes / Lisa R. HAMRICK in Autism Research, 17-11 (November 2024)

This heterogeneity can complicate the diagnostic and screening processes and can result in delayed or missed diagnoses. In this study, we characterize various profiles of nonverbal communication skills among 215 pre-verbal children with autism (Mage?=?36.27?months, range?=?18?70) and explore how these profiles are related to screening outcomes, diagnostic certainty, and developmental and behavioral features. We conducted a latent class analysis of nine items assessing nonverbal communication skills from the Toddler Module and Module 1 of the Autism Diagnostic Observation Schedule, 2nd Edition. Five nonverbal profiles were identified that differentiated children based on the form, function, and frequency of their nonverbal communication skills. Furthermore, screening outcomes and clinician certainty in autism diagnosis varied by nonverbal profile. False negative screening outcomes based on parent report were highest for children who used a range of nonverbal skills but with limited frequency or consistency. Clinicians, on the other hand, tended to have high certainty in an autism diagnosis for children with this profile, and instead rated their lowest certainty in diagnosing children who demonstrated consistent integration of eye contact with their nonverbal communication. The profiles identified in this study could be clinically useful in helping to identify children at highest likelihood of being overlooked during the screening or diagnostic processes, providing an opportunity to improve early identification and intervention for autism.
