Wetherby, Amy M.; Guthrie, Whitney; Hooker, Jessica L.; Delehanty, Abigail; Day, Taylor N.; Woods, Juliann; Pierce, Karen; Manwaring, Stacy S.; Thurm, Audrey; Ozonoff, Sally; Petkova, Eva; Lord, Catherine – Autism: The International Journal of Research and Practice, 2021
There is a critical need for validated screening tools for autism spectrum disorder in very young children so families can access tailored intervention services as early as possible. Few screeners exist for children between the recommended screening ages of 18-24 months. This study examined the utility of a new autism-specific parent-report…

Wetherby, Amy M.; Woods, Juliann; Guthrie, Whitney; Delehanty, Abigail; Brown, Jennifer A.; Morgan, Lindee; Holland, Renee D.; Schatschneider, Christopher; Lord, Catherine – Journal of Speech, Language, and Hearing Research, 2018
Purpose: The need for community-viable, evidence-based intervention strategies for toddlers with autism spectrum disorder (ASD) is a national priority. The purpose of this research forum article is to identify gaps in intervention research and needs in community practice for toddlers with ASD, incorporate published findings from a randomized…

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…

Dow, Deanna; Guthrie, Whitney; Stronach, Sheri T.; Wetherby, Amy M. – Autism: The International Journal of Research and Practice, 2017
The purpose of this study was to examine the utility of the Systematic Observation of Red Flags as an observational level-two screening measure to detect risk for autism spectrum disorder in toddlers when used with a video-recorded administration of the Communication and Symbolic Behavior Scales. Psychometric properties of the Systematic…

Plumb, Allison M.; Wetherby, Amy M. – Journal of Speech, Language, and Hearing Research, 2013
Purpose: In this study, the authors aimed to examine the vocalizations of children with autism spectrum disorder (ASD) in the second year of life and their relationship to other areas of development. Method: Vocalizations were examined in 125 children between ages 18 and 24 months: 50 later diagnosed with ASD, 25 with developmental delays (DD) in…

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…

Stronach, Sheri; Wetherby, Amy M. – Autism: The International Journal of Research and Practice, 2014
This prospective study of the FIRST WORDS® Project examined restricted and repetitive behaviors in a sample of 55 toddlers at a mean age of 20 months who were later diagnosed with autism spectrum disorder. Restricted and repetitive behaviors were coded using the Repetitive Movement and Restricted Interest Scales in two video-recorded observation…

Steven; Roberts, Wendy; Rogers, Sally J.; Schertz, Hannah H.; Smith, Isabel M.; Stone, Wendy L.; Watson, Linda R.; Wetherby, Amy M.; Yoder, Paul J.; Zwaigenbaum, Lonnie – Journal of Early Intervention, 2013
Given recent advances in science, policy, and practice of early identification in autism spectrum disorder (ASD), questions about the effectiveness of early intervention have far-reaching service and policy implications. However, rigorous research evaluating the efficacy and effectiveness of intervention programs for toddlers with ASD faces a…

Watt, Nola; Wetherby, Amy M.; Barber, Angie; Morgan, Lindee – Journal of Autism and Developmental Disorders, 2008
This study examined repetitive and stereotyped behaviors (RSB) in children with autism spectrum disorders (ASD, n = 50), developmental delays without ASD (DD; n = 25) and typical development (TD, n = 50) between 18 and 24 months of age. Children with ASD demonstrated significantly higher frequency and longer duration of RSB with objects, body, and…

Wetherby, Amy M.; Watt, Nola; Morgan, Lindee; Shumway, Stacy – Journal of Autism and Developmental Disorders, 2007
This study examined social communication profiles from behavior samples videotaped between 18 and 24 months of age in three groups of children: 50 with autism spectrum disorders (ASD), 23 with developmental delays (DD), and 50 with typical development (TD). The ASD group scored significantly lower than the DD group on 5 social communication…

Wetherby, Amy M.; Woods, Juliann J. – Topics in Early Childhood Special Education, 2006
The Early Social Interaction (ESI) Project (Woods & Wetherby, 2003) was designed to apply the recommendations of the National Research Council (2001) to toddlers with autism spectrum disorders (ASD) by using a parent-implemented intervention that (a) embeds naturalistic teaching strategies in everyday routines and (b) is compatible with the…

Woods, Juliann J.; Wetherby, Amy M. – Language, Speech, and Hearing Services in Schools, 2003
This article first reviews early social and communication indicators of autism spectrum disorder (ASD) in infants and toddlers. It then reviews evidence-based intervention practices for children with ASD and identifies principles for providing intervention for infants and toddlers at risk for ASD. Issues addressed include providing intervention in…

Prizant, Barry M.; Wetherby, Amy M.; Rubin, Emily; Laurent, Amy C. – Infants and Young Children, 2003
This article describes the SCERTS Model, which prioritizes social communication, emotional regulation, and transactional support as the primary developmental dimensions that programs supporting young children with autistic spectrum disorders must address. The SCERTS Model has been derived from theoretical and empirical bases, is consistent with…
