Background & Aims: Social communication and language skills have been found to be important predictors of long-term outcomes in individuals with autism spectrum disorder (ASD). However, the development of coordinated social communication (i.e., gestures and sounds or words) remains relatively understudied in young children with ASD and…

Guthrie, Whitney; Wetherby, Amy M.; Woods, Juliann; Schatschneider, Christopher; Holland, Renee D.; Morgan, Lindee; Lord, Catherine E. – Autism: The International Journal of Research and Practice, 2023
Robust evidence supports the efficacy of early autism intervention. Despite broad consensus that earlier intervention leads to better outcomes, evidence for this has been limited to correlational studies. This study examined timing effects of the Early Social Interaction (ESI) model, a parent-implemented intervention, using a complete crossover…

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…

Chambers, Nola; Stronach, Sheri T.; Wetherby, Amy M. – International Journal of Language & Communication Disorders, 2016
Background: Substantial development in social communication skills occurs in the first two years of life. Growth should be evident in sharing emotion and eye gaze; rate of communication, communicating for a variety of functions; using gestures, sounds and words; understanding language, and using functional and pretend actions with objects in play.…

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…

Shumway, Stacy; Wetherby, Amy M. – Journal of Speech, Language, and Hearing Research, 2009
Purpose: To examine the communicative profiles of children with autism spectrum disorders (ASD) in the second year of life. Method: Communicative acts were examined in 125 children 18 to 24 months of age: 50 later diagnosed with ASD; 25 with developmental delays (DD); and 50 with typical development (TD). Precise measures of rate, functions, and…

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…

There is an urgent requirement for the improvement of early detection of ASDs. This article provides a brief review of research on the accuracy of screeners for children with ASD that have been administered to general pediatric samples and then present results of a population-based study with a broadband screener to detect children with…

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…
