Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White;…

Achermann, Sheila; Falck-Ytter, Terje; Bölte, Sven; Nyström, Pär – Journal of Autism and Developmental Disorders, 2021
In typical development, infants form predictions about future events based on incoming sensory information, which is essential for perception and goal-directed action. It has been suggested that individuals with autism spectrum disorder (ASD) make predictions differently compared to neurotypical individuals. We investigated how infants who later…

Sasayama, Daimei; Kudo, Tetsuya; Kaneko, Wakako; Kuge, Rie; Koizumi, Noriaki; Nomiyama, Tetsuo; Washizuka, Shinsuke; Honda, Hideo – Journal of Autism and Developmental Disorders, 2021
The present study aimed to identify the cumulative incidence of autism spectrum disorder (ASD) in a thoroughly screened population and to examine the behavioral and motor characteristics observed in children with ASD at the age of 18 months. Subjects were 1067 children who underwent a screening assessment for ASD at the routine 18-months health…

Larsen, Kenneth; Aasland, Astrid; Schjølberg, Synnve; Hansen, Ulla I.; Diseth, Trond H. – Journal of Autism and Developmental Disorders, 2020
Early symptoms of autism spectrum disorder (ASD) develop through the second year of life, making a stable ASD diagnosis possible around 24 months of age. However, in general, children with ASD are diagnosed later. In this study we explored the use of a short observation list to detect symptoms associated with ASD in children 12-24 months of age…

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…

Peters, W. Jason; Matson, Johnny L. – Journal of Autism and Developmental Disorders, 2020
With the publication of DSM-5, many changes were introduced regarding how Autism Spectrum Disorder (ASD) would be diagnosed. Changes from DSM-IV-TR were controversial, with many arguing that individuals would lose their diagnosis with the new criteria. The purpose of this study was to examine differences in the application of diagnostic criteria…

The objectives were to characterize behavioral signs of autism spectrum disorder (ASD) in younger siblings of diagnosed children (high-risk; HR) and examine classification features of the Autism Observation Scale for Infants (AOSI). Participants (501 HR and 180 low-risk [LR]) were assessed between 6 and 18 months using the AOSI and at age 3 for…

Choi, Boin; Shah, Priyanka; Rowe, Meredith L.; Nelson, Charles A.; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2021
We investigated gestures that parents used with 12-, 18-, and 24-month-old infants at high or low risk for autism spectrum disorder (ASD; high-risk diagnosed with ASD: n = 21; high-risk classified as no ASD: n = 34; low-risk classified as no ASD: n = 34). We also examined infant responses to parent gestures and assessed the extent to which parent…

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…

Gangi, Devon N.; Boterberg, Sofie; Schwichtenberg, Amy J.; Solis, Erika; Young, Gregory S.; Iosif, Ana-Maria; Ozonoff, Sally – Child Development, 2021
Two independent cohorts (N = 155, N = 126) of infants at high and low risk for autism spectrum disorder (ASD) were followed prospectively between 6 and 36 months of age, when n = 46 were diagnosed with ASD. Gaze to adult faces was coded--during a developmental assessment (Cohort 1) or a play interaction (Cohort 2). Across both cohorts, most…

Demchick, Barbara B.; Flanagan, Joanne; Parete, Taylor; Matteo, Danielle – Journal of Occupational Therapy, Schools & Early Intervention, 2019
It is important to identify Autism Spectrum Disorder (ASD) early to alleviate its developmental impact. This pilot correlational study aimed to identify subtle differences in play and movement in 6-month-old infants that are associated with a later ASD diagnosis through retrospective home video analysis of six children with ASD and nine typically…

Unwin, Lisa M.; Bruz, Ildiko; Maybery, Murray T.; Reynolds, Victoria; Ciccone, Natalie; Dissanayake, Cheryl; Hickey, Martha; Whitehouse, Andrew J. O. – Journal of Autism and Developmental Disorders, 2017
There is preliminary evidence that infant siblings of children with Autism Spectrum Disorder (ASD) have an atypical pattern of cry, characterized by higher fundamental frequency and increased dysphonation. This prospective study collected multiple cry samples of 12-month old siblings of children with ASD (n = 22, "high-risk" group) and…

West, Kelsey L.; Roemer, Emily J.; Northrup, Jessie B.; Iverson, Jana M. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Infants with autism spectrum disorder (ASD) produce fewer play actions and gestures than neurotypical infants (e.g., Mastrogiuseppe et al., 2015; Veness et al., 2012; Zwaigenbaum et al., 2005). The purpose of this study was to investigate whether different "types" of actions and gestures are more or less likely to develop…

Sustainability of an Early Detection Program for Autism Spectrum Disorder over the Course of 8 Years
Pijl, Mirjam K. J.; Buitelaar, Jan K.; de Korte, Manon W. P.; Rommelse, Nanda N. J.; Oosterling, Iris J. – Autism: The International Journal of Research and Practice, 2018
The importance of early detection of autism spectrum disorder followed by early intervention is increasingly recognized. This quasi-experimental study evaluated the long-term effects of a program for the early detection of autism spectrum disorder (consisting of training of professionals and use of a referral protocol and screening instrument), to…

Macari, Suzanne L.; Wu, Grace C.; Powell, Kelly K.; Fontenelle, Scuddy, IV; Macris, Deanna M.; Chawarska, Katarzyna – Journal of Autism and Developmental Disorders, 2018
Given the emphasis on early screening for ASD, it is crucial to examine the concordance between parent report and clinician observation of autism-related behaviors. Similar items were compared from the First Year Inventory (Baranek et al. "First-Year Inventory (FYI) 2.0." University of North Carolina, Chapel Hill, 2003), a parent…
