Chambers, Nola J.; Wetherby, Amy M.; Stronach, Sheri T.; Njongwe, Nonyameko; Kauchali, Shuaib; Grinker, Richard R. – Autism: The International Journal of Research and Practice, 2017
Culturally appropriate tools are needed for detecting symptoms of autism spectrum disorder in young South African children. The objectives of this study were to (1) adapt and translate into isiZulu existing measures for detecting early signs of autism spectrum disorder, (2) use the measures to characterize and compare behavioural profiles of young…

McCormick, Carolyn; Hepburn, Susan; Young, Gregory S.; Rogers, Sally J. – Autism: The International Journal of Research and Practice, 2016
Sensory symptoms are prevalent in autism spectrum disorder but little is known about the early developmental patterns of these symptoms. This study examined the development of sensory symptoms and the relationship between sensory symptoms and adaptive functioning during early childhood. Three groups of children were followed across three time…

Drahota, Amy; Sadler, Richard; Hippensteel, Christopher; Ingersoll, Brooke; Bishop, Lauren – Autism: The International Journal of Research and Practice, 2020
Autism spectrum disorder and co-occurring symptoms often require lifelong services. However, access to autism spectrum disorder services is hindered by a lack of available autism spectrum disorder providers. We utilized geographic information systems methods to map autism spectrum disorder provider locations in Michigan. We hypothesized that (1)…

Talbott, Meagan R.; Dufek, Sarah; Zwaigenbaum, Lonnie; Bryson, Susan; Brian, Jessica; Smith, Isabel M.; Rogers, Sally J. – Journal of Autism and Developmental Disorders, 2020
Families with early concerns about infant symptoms of ASD have limited access to experienced professionals for screening and guidance. Telehealth has been used to reduce access disparities in other pediatric populations and has shown promise in parent-implemented interventions for ASD. We investigated the feasibility of a novel level-2 telehealth…

Fisher, Wayne W.; Luczynski, Kevin C.; Blowers, Andrew P.; Vosters, Megan E.; Pisman, Maegan D.; Craig, Andy R.; Hood, Stephanie A.; Machado, Mychal A.; Lesser, Aaron D.; Piazza, Cathleen C. – Journal of Applied Behavior Analysis, 2020
Parents play an important role in the treatment of their children's symptoms of autism spectrum disorder (ASD); thus, developing effective, efficient, socially acceptable, and accessible procedures for training parents to implement applied-behavior-analysis (ABA) interventions is critically important. One potential approach involves delivering…

van Hulst, Branko M.; de Zeeuw, Patrick; Bos, Dienke J.; Rijks, Yvonne; Neggers, Sebastiaan F. W.; Durston, Sarah – Journal of Child Psychology and Psychiatry, 2017
Background: Changes in reward processing are thought to be involved in the etiology of attention-deficit/hyperactivity disorder (ADHD), as well as other developmental disorders. In addition, different forms of therapy for ADHD rely on reinforcement principles. As such, improved understanding of reward processing in ADHD could eventually lead to…

Mayes, Susan Dickerson; Calhoun, Susan L.; Mayes, Rebecca D.; Molitoris, Sarah – Research in Autism Spectrum Disorders, 2012
Children with ADHD and autism have some similar features, complicating a differential diagnosis. The purpose of our study was to determine the degree to which core ADHD and autistic symptoms overlap in and discriminate between children 2-16 years of age with autism and ADHD. Our study demonstrated that 847 children with autism were easily…
