Peer reviewed Peer reviewed

Ellison, Kimberly; Bundy, Myra Beth; Gore, Jon; Wygant, Dustin – Exceptionality, 2019
With the publication of "DSM-5," clinical assessment of Autism Spectrum Disorder (ASD) has begun to follow a new dimensional framework which includes new severity specifiers. Little research has explored these severity ratings in comparison to other previously established severity indicators (e.g. "ADOS-2" calibrated severity…

Longitudinal Study of Symptom Severity and Language in Minimally Verbal Children with Autism
Peer reviewed Peer reviewed

Thurm, Audrey; Manwaring, Stacy S.; Swineford, Lauren; Farmer, Cristan – Journal of Child Psychology and Psychiatry, 2015
Background: A significant minority of children with autism spectrum disorder (ASD) are considered "minimally verbal" due to language development stagnating at a few words. Recent developments allow for the severity of ASD symptoms to be examined using Autism Diagnostic Observation Schedule (ADOS) Social Affect (SA) and Restricted and…

K.; Baron-Cohen, S.; Bedford, R.; Bolton, P.; Blasi, A.; Chandler, S.; Cheung, C.; Davies, K.; Elsabbagh, M.; Fernandes, J.; Gammer, I.; Garwood, H.; Gliga, T.; Guiraud, J.; Hudry, K.; Liew, M.; Lloyd-Fox, S.; Maris, H.; O'Hara, L.; Pasco, G.; Pickles, A.; Ribeiro, H.; Salomone, E.; Tucker, L.; Volein, A. – Journal of Autism and Developmental Disorders, 2018
We integrated multiple behavioural and developmental measures from multiple time-points using machine learning to improve early prediction of individual Autism Spectrum Disorder (ASD) outcome. We examined Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, and early ASD symptoms between 8 and 36 months in high-risk siblings (HR; n…

Early Diagnosis of Autism Spectrum Disorder: Stability and Change in Clinical Diagnosis and Symptom Presentation
Peer reviewed Peer reviewed
Direct linkDirect link
Guthrie, Whitney; Swineford, Lauren B.; Nottke, Charly; Wetherby, Amy M. – Journal of Child Psychology and Psychiatry, 2013
Background: Although a diagnosis of autism spectrum disorder (ASD) appears to be stable in children as young as age three, few studies have explored stability of a diagnosis in younger children. Predictive value of diagnostic tools for toddlers and patterns of symptom change are important considerations for clinicians making early diagnoses. Most…

Wan, Ming Wai; Green, Jonathan; Elsabbagh, Mayada; Johnson, Mark; Charman, Tony; Plummer, Faye – Journal of Child Psychology and Psychiatry, 2013
Background: Recent models of the early emergence of autism spectrum disorder (ASD) propose that infant intrinsic risk susceptibilities in behaviour may be amplified by interaction within the early social environment into an increasingly atypical developmental trajectory. This study examines whether 6- and 12-month parent-infant interactions in…
