Autism Symptomatology in Boys with Fragile X Syndrome: A Cross Sectional Developmental Trajectories Comparison with Nonsyndromic Autism Spectrum Disorder / Angela John THURMAN in Journal of Autism and Developmental Disorders, 45-9 (September 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-9 (September 2015) . - p.2816-2832 Titre : Autism Symptomatology in Boys with Fragile X Syndrome: A Cross Sectional Developmental Trajectories Comparison with Nonsyndromic Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Angela John THURMAN, Auteur ; Andrea MCDUFFIE, Auteur ; Sara T. KOVER, Auteur ; Randi J. HAGERMAN, Auteur ; Leonard ABBEDUTO, Auteur Article en page(s) : p.2816-2832 Langues : Anglais (eng) Mots-clés : Fragile X syndrome  Autism spectrum disorder  Behavioral phenotype  Nonverbal cognition  Expressive vocabulary  Developmental trajectory Index. décimale : PER Périodiques Résumé : Although males with fragile X syndrome (FXS) are frequently described as demonstrating autism symptomatology, there is much debate regarding whether the behavioral symptoms representing the core domains of autism are the result of the same or different underlying neurological/psychological mechanisms. The present study used a cross-sectional developmental trajectories approach to compare the profiles of autism symptomatology relative to chronological age (CA), nonverbal IQ, and expressive vocabulary ability between individuals with FXS and individuals with nonsyndromic ASD. Results suggest that the onset of autism symptoms and their developmental trajectories in males with FXS differ in important ways as a function of CA, nonverbal cognitive ability, and expressive vocabulary relative to males with nonsyndromic ASD. Theoretical and clinical implications are discussed.

Brief Report: Parent Verbal Responsiveness and Language Development in Toddlers on the Autism Spectrum / Eileen HAEBIG in Journal of Autism and Developmental Disorders, 43-9 (September 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-9 (September 2013) . - p.2218-2227 Titre : Brief Report: Parent Verbal Responsiveness and Language Development in Toddlers on the Autism Spectrum Type de document : Texte imprimé et/ou numérique Auteurs : Eileen HAEBIG, Auteur ; Andrea MCDUFFIE, Auteur ; Susan ELLIS WEISMER, Auteur Article en page(s) : p.2218-2227 Langues : Anglais (eng) Mots-clés : Autism  Parent responsiveness  Parent–child interactions Index. décimale : PER Périodiques Résumé : This study examined the longitudinal associations between parent verbal responsiveness and language 3 years later in 34 toddlers with a diagnosis of an autism spectrum disorder. Parent–child play samples were coded for child engagement and communication acts and for parent verbal responsiveness. Measures of responsive verbal behaviors were used to predict language gain scores 3 years later. Parent directives for language that followed into the child’s focus of attention were predictive of child receptive language gains. Parent comments that followed into the child’s focus of attention yielded differential effects depending on initial levels of child language. Children who were minimally verbal at age 2½ benefited from parent comments that followed into the their focus of attention, whereas children who were verbally fluent did not demonstrate such a benefit.

A comparison of contexts for assessing joint attention in toddlers on the autism spectrum / Elizabeth M. ROOS in Autism, 12-3 (May 2008)

Structured measures, such as the Early Social Communication Scales (ESCS), are commonly used to provide a metric of joint attention. To explore the assessment of joint attention in multiple contexts, we implemented an alternative system for coding joint attention behaviors. We compared initiation of joint attention (IJA) and response to joint attention (RJA) behaviors coded from naturalistic examiner—child play samples with similar IJA and RJA behaviors elicited within the structured ESCS protocol. Participants were 20 toddlers on the autism spectrum. Levels of IJA and RJA within the two assessment contexts were significantly and positively correlated, providing support for the use of naturalistic sampling of joint attention skills as a viable alternative, or supplement, to structured measures.

Developmental Correlates of Different Types of Motor Imitation in Young Children with Autism Spectrum Disorders / Andrea MCDUFFIE in Journal of Autism and Developmental Disorders, 37-3 (March 2007)

STONE, Auteur Année de publication : 2007 Article en page(s) : p.401-412 Langues : Anglais (eng) Mots-clés : Motor-imitation Index. décimale : PER Périodiques Résumé : This study used a concurrent correlational design to examine associations between three types of motor imitation with objects and three proposed correlates in 32 two- and three-year-old children diagnosed with ASD. Attention-following and fine motor ability were significant, unique correlates of imitation in an observational learning context. Attention-following was a significant correlate of imitation in a direct elicitation context. Social reciprocity was a significant correlate of imitation in an interactive play context. These associations were observed after controlling for general developmental level. Results support previous findings that motor imitation may not reflect a unitary construct for children with ASD and that different skills may underlie the performance of different types of motor imitation. Implications for interventions targeting motor imitation are discussed.

Distance delivery of a parent-implemented language intervention for young boys with fragile X syndrome / Lauren BULLARD in Autism & Developmental Language Impairments, 2 (January-December 2017)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 2 (January-December 2017) Titre : Distance delivery of a parent-implemented language intervention for young boys with fragile X syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Lauren BULLARD, Auteur ; Andrea MCDUFFIE, Auteur ; Leonard ABBEDUTO, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BackgroundIn addition to significant cognitive delays, boys with fragile X syndrome display phenotypic characteristics that include delays in language, inattention, social anxiety, and escape-maintained challenging behaviors. Despite these challenges, families affected by fragile X syndrome often have limited access to center-based intervention programs.MethodsThe present study utilized a multiple baseline design across participants to examine the preliminary effectiveness of a 12-week, parent-implemented spoken language intervention for three 5- to 7-year-old boys with fragile X syndrome. The goal of the intervention was to teach the biological mothers of each boy to use a set of verbally responsive language support strategies while participating in shared book reading activities with her child. All aspects of the intervention, including pre- and post-treatment measures, were delivered into the family?s home via distance video teleconferencing.ResultsResults from this study provide preliminary support for the efficacy of this parent-implemented language intervention approach by demonstrating generalized improvements in both targeted maternal strategy use and measures of child spoken language.ConclusionsThe present study expands upon prior language intervention research utilizing distance delivery of services for families affected by fragile X syndrome. Additionally, the study provides early support for the feasibility of collecting pre- and post-treatment assessments at a distance.
