In typical development, biological sex predicts inter-individual variation across multiple developmental milestones, with females often exhibiting earlier progression. The goal of this study was to examine sex differences in caregiver-reported developmental milestones (first word, phrase, walking) and their contribution to timing of initial concerns expressed by caregivers and eventual age of diagnosis. 195 (105 males) children and adolescents aged 8 to 17?years with a clinical diagnosis of ASD were recruited to the study (mean IQ = 99.76). While developmental milestones did not predict timing of diagnosis or age parents first expressed concerns, females had earlier first words and phrases than males. There was a marginal difference in the age of diagnosis, with females receiving their diagnosis 1?year later than males. Despite sex differences in developmental milestones and diagnostic variables, IQ was the most significant predictor in the timing of initial concerns and eventual diagnosis, suggesting children with lower IQ, regardless of sex, are identified and diagnosed earlier. Overall, biological sex and developmental milestones did not account for a large proportion of variance for the eventual age of ASD diagnosis, suggesting other factors (such as IQ and the timing of initial concerns) are potentially more influential. LAY SUMMARY: In this study, a later age of diagnosis in females having ASD was confirmed; however, biological sex was not the stronger predictor of age of diagnosis. Parents reported that females learned language more quickly than males, and parents noted their first concerns when females were older than males. In this sample, the strongest predictor of age of diagnosis was the age of first concerns.

Social Motivation Across Multiple Measures: Caregiver-Report of Children with Autism Spectrum Disorder / Emily NEUHAUS in Autism Research, 14-2 (February 2021)  

Public ISBD [article]  inAutism Research > 14-2 (February 2021) . - p.369-379 Titre : Social Motivation Across Multiple Measures: Caregiver-Report of Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Emily NEUHAUS, Auteur ; Raphael BERNIER, Auteur ; Sara J. WEBB, Auteur Article en page(s) : p.369-379 Langues : Anglais (eng) Mots-clés : affiliation  sex differences  social motivation  social skills Index. décimale : PER Périodiques Résumé : Social motivation is a foundational construct with regard to the etiology, neurobiology, and phenotype of autism spectrum disorder (ASD). Multiple theories suggest that early emerging alterations to social motivation underlie a developmental cascade of social and communication deficits across the lifespan. Despite this significance, methods to measure social motivation vary widely, with little data to date as to how different measures might compare. In this study, we explore three existing caregiver-report measures that have been proposed to quantify social motivation among school-age children with ASD (n = 18; all male) and without ASD (n = 36; 50% female), with the broad goal of characterizing social motivation across measures and specific aims of investigating (a) diagnostic and sex differences in social motivation, (b) correspondence between measures, and (c) relationships between social motivation and broader social outcomes. Across all three measures, individuals with ASD had lower social motivation by caregiver-report. However, they did display individual differences in the degree of social motivation reported. There were no differences in social motivation between males and females without ASD on any of the three measures. For the full sample, measures of social motivation correlated with one another as anticipated, and stronger social motivation was associated with stronger social skills and fewer social difficulties. Our data suggest that social motivation among children with ASD may be best conceptualized as an individual difference that is diminished on average relative to peers but which varies among children and adolescents with ASD, rather than as an absolute absence or uniform deficit. LAY SUMMARY: Several theories suggest that children with autism spectrum disorder (ASD) experience less social motivation than their peers without ASD, contributing to difficulties in social skills. Based on multiple caregiver-report questionnaires, social motivation was reduced on average for school-age children with ASD but also varied among children with ASD. Stronger social motivation was related to stronger social skills and fewer social problems. Future work should include more girls with ASD, consider social motivation across age groups, and include first-hand perspectives from people with ASD.
