Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Frazier, Thomas W.; Youngstrom, Eric A.; Embacher, Rebecca; Hardan, Antonio Y.; Constantino, John N.; Law, Paul; Findling, Robert L.; Eng, Charis – Autism: The International Journal of Research and Practice, 2014
Demographic and clinical factors may influence assessment of autism symptoms. This study evaluated these correlates and also examined whether social communication and interaction and restricted/repetitive behavior provided unique prediction of autism spectrum disorder diagnosis. We analyzed data from 7352 siblings included in the Interactive…

In order to shed more light on why referred girls are less likely to be diagnosed with autism spectrum disorder than boys, this study examined whether behavioral characteristics influence the probability of an autism spectrum disorder diagnosis differently in girls versus boys derived from a multicenter sample of consecutively referred children…

Little, Lauren M.; Wallisch, Anna; Salley, Brenda; Jamison, Rene – Autism: The International Journal of Research and Practice, 2017
Given that early caregiver concerns may be different for children who go on to receive a diagnosis of autism spectrum disorder versus another developmental disability, early caregiver concerns may differ for girls. Using a community-based sample of children (n = 241), we examined the extent to which gender differences may be related to caregiver…

Pellecchia, Melanie; Connell, James E.; Kerns, Connor M.; Xie, Ming; Marcus, Steven C.; Mandell, David S. – Autism: The International Journal of Research and Practice, 2016
This study examined the extent to which clinical and demographic characteristics predicted outcome for children with autism spectrum disorder. Participants included 152 students with autism spectrum disorder in 53 kindergarten-through-second-grade autism support classrooms in a large urban public school district. Associations between child…

Plumb, Allison M.; Wetherby, Amy M. – Journal of Speech, Language, and Hearing Research, 2013
Purpose: In this study, the authors aimed to examine the vocalizations of children with autism spectrum disorder (ASD) in the second year of life and their relationship to other areas of development. Method: Vocalizations were examined in 125 children between ages 18 and 24 months: 50 later diagnosed with ASD, 25 with developmental delays (DD) in…

Burger-Caplan, Rebecca; Saulnier, Celine; Jones, Warren; Klin, Ami – Autism: The International Journal of Research and Practice, 2016
The Social Attribution Task, Multiple Choice is introduced as a measure of implicit social cognitive ability in children, addressing a key challenge in quantification of social cognitive function in autism spectrum disorder, whereby individuals can often be successful in explicit social scenarios, despite marked social adaptive deficits. The…

Frenette, Priscilla; Dodds, Linda; MacPherson, Kathleen; Flowerdew, Gordon; Hennen, Brian; Bryson, Susan – Autism: The International Journal of Research and Practice, 2013
While early diagnosis of autism spectrum disorders (ASD) is essential for ensuring timely access to early intervention services, there is limited existing literature investigating factors that delay this diagnosis. This population-based cohort study explored the age at which children in Nova Scotia, Canada, are diagnosed with ASDs and the factors…

Scheeren, Anke M.; de Rosnay, Marc; Koot, Hans M.; Begeer, Sander – Journal of Child Psychology and Psychiatry, 2013
Background: The sociocommunicative problems in autism spectrum disorder (ASD) are traditionally linked to impairments in Theory of Mind (ToM), the ability to ascribe mental states to others. Although ToM impairments are consistently reported in young children with ASD, findings on more advanced ToM understanding in older individuals with…
