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…

The capacity of the Child Behavior Checklist 1½-5 (CBCL 1½-5) to identify children with autism spectrum disorder (ASD) at 18 months was tested on 37 children clinically referred for ASD and 46 children at elevated likelihood of developing ASD due to having an affected brother/sister. At 30 months the clinically referred children all received a…

Sacrey, Lori-Ann R.; Zwaigenbaum, Lonnie; Bryson, Susan; Brian, Jessica; Smith, Isabel M.; Roberts, Wendy; Szatmari, Peter; Vaillancourt, Tracy; Roncadin, Caroline; Garon, Nancy – Journal of Autism and Developmental Disorders, 2021
Despite considerable progress in characterizing the early signs of autism spectrum disorder (ASD), more remains to be learned about how symptoms emerge in the first year of life. Parents with a new baby who already had at least one biological child diagnosed with ASD (high-risk) or no family history of ASD (low-risk) completed two measures when…

Raza, Sarah; Zwaigenbaum, Lonnie; Sacrey, Lori-Ann R.; Bryson, Susan; Brian, Jessica; Smith, Isabel M.; Reid, Kyle; Roberts, Wendy; Szatmari, Peter; Vaillancourt, Tracy; Roncadin, Caroline; Garon, Nancy – Journal of Autism and Developmental Disorders, 2019
This study examined the potential of the short form of the Quantitative Checklist for Autism in Toddlers (Q-CHAT-10) to identify autism spectrum disorder (ASD) in a high-risk sibling cohort. High-risk (HR; siblings of children diagnosed with ASD) and low-risk (LR; no family history of ASD) toddlers were assessed prospectively at 18 and 24 months…

Wang, Jiaxing; Ding, Gang; Li, Ying; Hua, Ning; Wei, Nan; Qi, Xiaoli; Ning, Yuxian; Zhang, Ying; Li, Xue; Li, Jing; Song, Linlin; Qian, Xuehan – Journal of Autism and Developmental Disorders, 2018
Amblyopia risk factors in children with autism spectrum disorders (ASD) are usually hard to detect in early childhood due to poor cooperation and has not been reported in the Chinese population. We screened 168 Chinese children with ASD, aged between 3 and 8 years, and 264 age-matched neurotypical children with Spot photoscreener and basic…

Davidovitch, Michael; Stein, Nataly; Koren, Gideon; Friedman, Bat Chen – Journal of Autism and Developmental Disorders, 2018
This study was designed to track the developmental trajectory, during the first 24 months of life, of 335 low-risk infants later diagnosed with Autism Spectrum Disorder and identify early deviations observed in routine Well Care checkups. We compared their achievements to typically developing children and to children later diagnosed with…

Eisenhower, Abbey; Martinez Pedraza, Frances; Sheldrick, R. Christopher; Frenette, Elizabeth; Hoch, Noah; Brunt, Sophie; Carter, Alice S. – Journal of Autism and Developmental Disorders, 2021
Health disparities in ASD detection affect children's access to subsequent interventions. We examined potential disparities in implementation of a multi-stage ASD screening and diagnostic evaluation protocol in Part C Early Intervention with 4943 children ages 14-36 months (mean 22.0 months; 62.9% boys, 73.3% children of color, 34.9%…

Sturner, Raymond; Howard, Barbara; Bergmann, Paul; Stewart, Lydia; Afarian, Talin E. – Journal of Autism and Developmental Disorders, 2017
This study examined the effect of age at completion of an autism screening test on item failure rates contrasting older (>20 months) with younger (<20 months) toddlers in a community primary care sample of 73,564 children. Items related to social development were categorized into one of three age sets per criteria from Inada et al.…

Clinical Evaluation of a Novel and Mobile Autism Risk Assessment
Peer reviewed Peer reviewed

Duda, Marlena; Daniels, Jena; Wall, Dennis P. – Journal of Autism and Developmental Disorders, 2016
The Mobile Autism Risk Assessment (MARA) is a new, electronically administered, 7-question autism spectrum disorder (ASD) screen to triage those at highest risk for ASD. Children 16 months-17 years (N = 222) were screened during their first visit in a developmental-behavioral pediatric clinic. MARA scores were compared to diagnosis from the…

Gabard-Durnam, Laurel; Tierney, Adrienne L.; Vogel-Farley, Vanessa; Tager-Flusberg, Helen; Nelson, Charles A. – Journal of Autism and Developmental Disorders, 2015
An emerging focus of research on autism spectrum disorder (ASD) targets the identification of early-developing ASD endophenotypes using infant siblings of affected children. One potential neural endophenotype is resting frontal electroencephalogram (EEG) alpha asymmetry, a metric of hemispheric organization. Here, we examined the development of…
