Pérez-García, Débora; Brun-Gasca, Carme; Pérez-Jurado, Luis A.; Mervis, Carolyn B. – American Journal on Intellectual and Developmental Disabilities, 2017
To identify similarities and differences in the behavioral profile of children with Williams syndrome from Spain (n = 53) and the United States (n = 145), we asked parents of 6- to 14-year-olds with Williams syndrome to complete the Child Behavior Checklist 6-18. The distribution of raw scores was significantly higher for the Spanish sample than…

Neo, Wei Siong; Tonnsen, Bridgette L. – Journal of Autism and Developmental Disorders, 2019
Children with neurogenetic syndromes (NGS) experience comorbid challenging behaviors and psychopathology. We examined challenging behaviors in 86 toddlers and preschoolers across three NGS [Angelman syndrome (AS), Prader--Willi syndrome (PWS), and Williams syndrome (WS)] and 43 low-risk controls (LRC), using the Child Behavior Checklist for Ages…

Klein-Tasman, Bonita P.; Lira, Ernesto N.; Li-Barber, Kirsten T.; Gallo, Frank J.; Brei, Natalie G. – American Journal on Intellectual and Developmental Disabilities, 2015
Problem behavior of 52 children with Williams syndrome ages 6 to 17 years old was examined based on both parent and teacher report. Generally good inter-rater agreement was found. Common areas of problem behavior based both on parent and teacher report included attention problems, anxiety difficulties, repetitive behaviors (e.g., obsessions,…

Lane, C.; Van Herwegen, J.; Freeth, M. – Journal of Intellectual Disability Research, 2019
Background: Sotos syndrome is a congenital overgrowth condition associated with intellectual disability and an uneven cognitive profile. Previous research has established that individuals with Sotos syndrome have relatively poor mathematical ability, but domain-specific numeracy skills have not been explored within this population. This study…

Valdes, Francisca; Keary, Christopher J.; Mullett, Jennifer E.; Palumbo, Michelle L.; Waxler, Jessica L.; Pober, Barbara R.; McDougle, Christopher J. – Journal of Autism and Developmental Disorders, 2018
Descriptions of individuals with Williams syndrome (WS) and co-morbid major depressive disorder (MDD) with psychotic features have not appeared in the literature. In addition to reviewing previous reports of psychotic symptoms in persons with WS, this paper introduces clinical histories and therapeutic management strategies for three previously…

Van Herwegen, Jo; Ranzato, Erica; Karmiloff-Smith, Annette; Simms, Victoria – Journal of Autism and Developmental Disorders, 2019
It has been reported that approximate number sense (ANS) task performance is impaired in individuals with Williams syndrome (WS) and Down syndrome (DS). Research with infants has suggested this impairment is caused by sticky fixation in WS and sustained attention deficits for those with DS. This study examined looking patterns of older children…

Mervis, Carolyn B.; Greiner de Magalhães, Caroline; Cardoso-Martins, Cláudia – Reading and Writing: An Interdisciplinary Journal, 2022
We examined the cognitive, language, and instructional factors associated with reading ability in Williams syndrome (WS). Seventy 9-year-olds with WS completed standardized measures of real-word reading, pseudoword decoding, reading comprehension, phonological skills, listening comprehension, nonverbal reasoning, visual-spatial ability, verbal…

Baptista, Joana; Sampaio, Adriana; Fachada, Inês; Osório, Ana; Mesquita, Ana R.; Garayzabal, Elena; Duque, Frederico; Oliveira, Guiomar; Soares, Isabel – Journal of Autism and Developmental Disorders, 2019
This study compared maternal responsiveness to children with two neurodevelopmental disorders sharing different but, in some cases, overlapping social phenotypes--Williams syndrome (WS) and autism spectrum disorder (ASD)--and explored the relations between maternal responsiveness and child emotional/behavioural problems (EBP). The sample included…

Background: People with learning disabilities experience bereavement in the same emotionally overwhelming way as the general population. The Dual-Process Model of grief is characterised by the oscillation between "Loss-Orientation" and "Restoration-Orientation." These processes involve experiencing and accepting the emotional…

Nordahl-Hansen, Anders; Donolato, Enrica; Lervåg, Arne; Norbury, Courtenay Frazier; Melby-Lervåg, Monica – Campbell Systematic Reviews, 2019
This protocol presents the plan for a systematic review that investigates the effect of oral language interventions for children with intellectual disability (ID), language disorder (LD), autism spectrum disorder (ASD), Down syndrome (DS), Williams syndrome (WS), and fragile X syndrome (FXS). Language development is a highly frequent area of…

Lai, Philip T.; Ng, Rowena; Bellugi, Ursula – International Journal of Developmental Disabilities, 2022
The majority of the research examining children with Autism Spectrum Disorder (ASD) and Williams Syndrome (WS) focus on the social domain while few have examined cognitive style and emotionality. Accordingly, this current study assessed the day-to-day cognitive and behavioral functioning of school-age children with ASD, WS, and neurotypical…

Ashworth, Maria; Palikara, Olympia; Van Herwegen, Jo – Journal of Applied Research in Intellectual Disabilities, 2019
Background: Although parental stress is higher for children with neurodevelopmental disorders (NDs), it is unclear how this stress compares to more common NDs. The current study compared stress in parents of children with Williams syndrome (WS), Down syndrome (DS) and autism spectrum disorders (ASD). The impact of individual and contextual factors…

Palikara, Olympia; Ashworth, Maria; Van Herwegen, Jo – Journal of Autism and Developmental Disorders, 2018
Williams syndrome (WS) is a rare neurodevelopmental disorder associated with physical health problems, limitations in cognitive abilities and increased risk of mental health difficulties. This profile of complex needs may make it challenging to support children with WS in schools. Surprisingly, in the current international move for inclusion,…

Lane, Chloe; Van Herwegen, Jo; Freeth, Megan – Journal of Autism and Developmental Disorders, 2019
Sotos syndrome is a congenital overgrowth syndrome associated with intellectual disability. This study investigated communicative abilities of children with Sotos syndrome (n = 31), using the Children's Communication Checklist, second edition. A cross-syndrome approach was used to establish the specificity of these abilities. Children with…

Ng-Cordell, Elise; Hanley, Mary; Kelly, Alyssa; Riby, Deborah M. – Journal of Autism and Developmental Disorders, 2018
Anxiety is a prevalent mental health issue for individuals with Williams syndrome (WS). Relatively little is known about the developmental course of anxiety, or how it links with core features of WS, namely social and executive functioning (EF). In this study, parent-reports of anxiety were compared across a 4-year period (N = 17), and links…
