Jones, Rebecca M.; Tarpey, Thaddeus; Hamo, Amarelle; Carberry, Caroline; Brouwer, Gijs; Lord, Catherine – Journal of Autism and Developmental Disorders, 2018
Statistical learning-extracting regularities in the environment-may underlie complex social behavior. 124 children, 56 with autism and 68 typically developing, ages 2-8 years, completed a novel visual statistical learning task on an iPad. Averaged together, children with autism demonstrated less learning on the task compared to typically…

Jones, Rebecca M.; Southerland, Audrey; Hamo, Amarelle; Carberry, Caroline; Bridges, Chanel; Nay, Sarah; Stubbs, Elizabeth; Komarow, Emily; Washington, Clay; Rehg, James M.; Lord, Catherine; Rozga, Agata – Journal of Autism and Developmental Disorders, 2017
Children with autism have atypical gaze behavior but it is unknown whether gaze differs during distinct types of reciprocal interactions. Typically developing children (N = 20) and children with autism (N = 20) (4-13 years) made similar amounts of eye contact with an examiner during a conversation. Surprisingly, there was minimal eye contact…

Grzadzinski, Rebecca; Carr, Themba; Colombi, Costanza; McGuire, Kelly; Dufek, Sarah; Pickles, Andrew; Lord, Catherine – Journal of Autism and Developmental Disorders, 2016
Psychometric properties and initial validity of the Brief Observation of Social Communication Change (BOSCC), a measure of treatment-response for social-communication behaviors, are described. The BOSCC coding scheme is applied to 177 video observations of 56 young children with ASD and minimal language abilities. The BOSCC has high to excellent…

Esler, Amy N.; Bal, Vanessa Hus; Guthrie, Whitney; Wetherby, Amy; Weismer, Susan Ellis; Lord, Catherine – Journal of Autism and Developmental Disorders, 2015
Standardized calibrated severity scores (CSS) have been created for Autism Diagnostic Observation Schedule, 2nd edition (ADOS-2) Modules 1-4 as a metric of the relative severity of autism-specific behaviors. Total and domain CSS were created for the Toddler Module to facilitate comparison to other modules. Analyses included 388 children with ASD…

Reinhardt, Vanessa P.; Wetherby, Amy M.; Schatschneider, Christopher; Lord, Catherine – Journal of Autism and Developmental Disorders, 2015
Despite consistent and substantive research documenting a large male to female ratio in Autism Spectrum Disorder (ASD), only a modest body of research exists examining sex differences in characteristics. This study examined sex differences in developmental functioning and early social communication in children with ASD as compared to children with…

Cicchetti, Domenic V.; Lord, Catherine; Koenig, Kathy; Klin, Ami; Volkmar, Fred R. – Journal of Autism and Developmental Disorders, 2014
In an earlier investigation, the authors assessed the reliability of the ADI-R when multiple clinicians evaluated a single case, here a female 3 year old toddler suspected of having an autism spectrum disorder (Cicchetti et al. in "J Autism Dev Disord" 38:764-770, 2008). Applying the clinical criteria of Cicchetti and Sparrow ("Am J…

Kim, So Hyun; Junker, Dörte; Lord, Catherine – Journal of Autism and Developmental Disorders, 2014
A new language measure, the Observation of Spontaneous Expressive Language (OSEL), is intended to document spontaneous use of syntax, pragmatics, and semantics in 2-12-year-old children with Autism Spectrum Disorder (ASD) and other communication disorders with expressive language levels comparable to typical 2-5 year olds. Because the purpose of…

Estes, Annette; Vismara, Laurie; Mercado, Carla; Fitzpatrick, Annette; Elder, Lauren; Greenson, Jessica; Lord, Catherine; Munson, Jeffrey; Winter, Jamie; Young, Gregory; Dawson, Geraldine; Rogers, Sally – Journal of Autism and Developmental Disorders, 2014
This study investigated the impact of a parent-coaching intervention based on the Early Start Denver Model (P-ESDM) on parenting-related stress and sense of competence. This was part of a multisite, randomized trial comparing P-ESDM (n = 49) with community intervention (n = 49) for children aged 12 and 24 months. The P-ESDM group reported no…

Hus, Vanessa; Gotham, Katherine; Lord, Catherine – Journal of Autism and Developmental Disorders, 2014
Standardized Autism Diagnostic Observation Schedule (ADOS) scores provide a measure of autism severity that is less influenced by child characteristics than raw totals (Gotham et al. in "Journal of Autism and Developmental Disorders," 39(5), 693-705 2009). However, these scores combine symptoms from the Social Affect (SA) and Restricted…

Hus, Vanessa; Lord, Catherine – Journal of Autism and Developmental Disorders, 2014
The recently published Autism Diagnostic Observation Schedule, 2nd edition (ADOS-2) includes revised diagnostic algorithms and standardized severity scores for modules used to assess younger children. A revised algorithm and severity scores are not yet available for Module 4, used with verbally fluent adults. The current study revises the Module 4…

Bishop, Somer L.; Hus, Vanessa; Duncan, Amie; Huerta, Marisela; Gotham, Katherine; Pickles, Andrew; Kreiger, Abba; Buja, Andreas; Lund, Sabata; Lord, Catherine – Journal of Autism and Developmental Disorders, 2013
Research suggests that restricted and repetitive behaviors (RRBs) can be subdivided into Repetitive Sensory Motor (RSM) and Insistence on Sameness (IS) behaviors. However, because the majority of previous studies have used the Autism Diagnostic Interview-Revised (ADI-R), it is not clear whether these subcategories reflect the actual organization…

Hus, Vanessa; Lord, Catherine – Journal of Autism and Developmental Disorders, 2013
The Autism Diagnostic Interview-Revised (ADI-R) is commonly used to inform diagnoses of autism spectrum disorders (ASD). Considering the time dedicated to using the ADI-R, it is of interest to expand the ways in which information obtained from this interview is used. The current study examines how algorithm totals reflecting past (ADI-Diagnostic)…

Kim, So Hyun; Lord, Catherine – Journal of Autism and Developmental Disorders, 2012
Autism Diagnostic Interview-Revised (Rutter et al. in "Autism diagnostic interview-revised." Western Psychological Services, Los Angeles, 2003) diagnostic algorithms specific to toddlers and young preschoolers were created using 829 assessments of children aged from 12 to 47 months with ASD, nonspectrum disorders, and typical development. The…

Grzadzinski, Rebecca; Di Martino, Adriana; Brady, Emily; Mairena, Maria Angeles; O'Neale, Matthew; Petkova, Eva; Lord, Catherine; Castellanos, F. Xavier – Journal of Autism and Developmental Disorders, 2011
We examined to what extent increased parent reports of autistic traits in some children with Attention Deficit Hyperactivity Disorder (ADHD) are the result of ADHD-related symptoms or qualitatively similar to the core characteristics of autism spectrum disorders (ASD). Results confirm the presence of a subgroup of children with ADHD and elevated…
