Girls, more than boys, experience a decrease in the severity of autism symptoms during childhood. It is unclear, however, which specific autistic behaviors change more for girls than for boys. Trajectories of autism symptoms were evaluated using the Autism Diagnostic Observation Schedule-calibrated severity scores (ADOS-CSS). Change in the…

Frazier, Thomas W.; Hauschild, Kathryn M.; Klingemier, Eric; Strauss, Mark S.; Hardan, Antonio Y.; Youngstrom, Eric A. – Journal of Intellectual & Developmental Disability, 2020
Background: Language assessment is a key element of evaluations of children and adolescents with neurodevelopmental disorders (NDDs). The present study examined the validity of a gaze-based receptive language index (RLI) in predicting language test results.Method: Participants included toddlers, pre-school, and school age children and adolescents…

Background: Children with autism spectrum disorder (ASD) demonstrate highly variable writing skills. Few studies have examined if engagement during writing assessments may differ for children with ASD and if task engagement is related to their writing assessment performance. This study examined narrative writing and broad task engagement in…

Frost, Kyle M.; Hong, Natalie; Lord, Catherine – American Journal on Intellectual and Developmental Disabilities, 2017
Individuals with autism spectrum disorder (ASD) tend to have significant delays in adaptive functioning. In this study, the relationship between adaptive behavior and ASD symptomatology was investigated in minimally verbal, school-aged children with ASD (n = 333). Both the social affect (SA) and restricted and repetitive behavior (RRB) domains…

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…

Mussey, Joanna L.; Ginn, Nicole C.; Klinger, Laura G. – Autism: The International Journal of Research and Practice, 2017
Differences in behavioral and cognitive profiles have been suggested to potentially impact the presentation of social and communication symptoms in females with autism spectrum disorder. This study examined gender differences in age of diagnosis, cognitive profiles, social communication symptomatology, and autism spectrum disorder symptom severity…

Anderson, George M.; Montazeri, Farhad; de Bildt, Annelies – Journal of Autism and Developmental Disorders, 2015
A network conceptualization might contribute to understanding the occurrence and interacting nature of behavioral traits in the autism realm. Networks were constructed based on correlations of item scores of the Autism Diagnostic Observation Schedule for Modules 1, 2 and 3 obtained for a group of 477 Dutch individuals with developmental disorders.…

Vitamin D deficiency has been proposed as a possible risk factor for developing autism spectrum disorder (ASD). 25-Hydroxyvitamin D3 (25(OH)D3) levels were examined in a cross-sectional population-based study in the Faroe Islands. The case group consisting of a total population cohort of 40 individuals with ASD (aged 15-24 years) had significantly…

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…

Differences in joint attention are prominent for some children with autism and are often used as an indicator of the disorder. This study examined the joint attention competencies of young children with autism who demonstrated joint attention ability and compared them to children with developmental delays. A total of 40 children with autism and…

This study examines the academic abilities of children and adolescents who were once diagnosed with an autism spectrum disorder, but who no longer meet diagnostic criteria for this disorder. These individuals have achieved social and language skills within the average range for their ages, receive little or no school support, and are referred to…

The validity of the calibrated severity scores on the ADOS as reported by Gotham et al. (J Autism Dev Disord 39: 693-705, "2009"), was investigated in an independent sample of 1248 Dutch children with 1455 ADOS administrations (modules 1, 2 and 3). The greater comparability between ADOS administrations at different times, ages and in…
