Longitudinal study of symptom severity and language in minimally verbal children with autism / Audrey THURM in Journal of Child Psychology and Psychiatry, 56-1 (January 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-1 (January 2015) . - p.97-104 Titre : Longitudinal study of symptom severity and language in minimally verbal children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Audrey THURM, Auteur ; Stacy S. MANWARING, Auteur ; Lauren SWINEFORD, Auteur ; Cristan FARMER, Auteur Article en page(s) : p.97-104 Langues : Anglais (eng) Mots-clés : Language  autism spectrum disorders  preschool children  assessment  minimally verbal Index. décimale : PER Périodiques Résumé : Background A significant minority of children with autism spectrum disorder (ASD) are considered ‘minimally verbal’ due to language development stagnating at a few words. Recent developments allow for the severity of ASD symptoms to be examined using Autism Diagnostic Observation Schedule (ADOS) Social Affect (SA) and Restricted and Repetitive Behaviors (RRB) domain severity scores. The aim of the current study was to explore language outcomes in a cohort of minimally verbal children with autism evaluated through the preschool years and determine if and how ASD symptom severity in core domains predicts the development of spoken language by age 5. Methods The sample consisted of 70 children with autism aged 1–5 years at the first evaluation who were examined at least 1 year later, during their fifth year of age. The ADOS overall level of language item was used to categorize children as minimally verbal or having phrase speech, and the Mullen Scales of Early Learning was used as a continuous measure of expressive language. Results At Time 1, 65% (n = 47) of children in the sample were minimally verbal and by Time 2, 36% (n = 17 of 47) of them had developed phrase speech. While the Time 1 ADOS calibrated severity scores did not predict whether or not a child remained minimally verbal at Time 2, change in the SA calibrated severity score (but not RRB) was predictive of the continuous measure of expressive language. However, change in SA severity no longer predicted continuous expressive language when nonverbal cognitive ability was added to the model. Conclusions Findings indicate that the severity of SA symptoms has some relationship with continuous language outcome, but not categorical. However, the omnipresent influence of nonverbal cognitive ability was confirmed in the current study, as the addition of it to the model rendered null the predictive utility of SA severity.

Patterns of skill attainment and loss in young children with autism / Audrey THURM in Development and Psychopathology, 26-1 (February 2014)  

Public ISBD [article]  inDevelopment and Psychopathology > 26-1 (February 2014) . - p.203-214 Titre : Patterns of skill attainment and loss in young children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Audrey THURM, Auteur ; Stacy S.

SWEDO, Auteur Article en page(s) : p.203-214 Langues : Français (fre) Index. décimale : PER Périodiques Résumé : The purpose of this study was to extend the literature on the ontogeny of autism spectrum disorder (ASD) by examining early attainment and loss of specific sociocommunicative skills in children with autism (AUT; n = 125), pervasive developmental disorder not otherwise specified (PDD-NOS; n = 42), nonspectrum developmental delays (n = 46), and typical development (n = 31). The ages of skill attainment and loss were obtained from a caregiver interview. The findings indicated that children with AUT, PDD-NOS, and developmental delays diverged from typically developing children in attainment of sociocommunicative skills early in the first year of life. Loss of at least one skill was reported in a majority of children with AUT and PDD-NOS. Significant delays in attainment of skills were also reported in children who lost skills. The wide variation in skill attainment and loss reported across children indicates that symptom onset and regression may be best represented continuously, with at least some early delay and loss present for a great majority of children with ASD.

A scoping review of deictic gesture use in toddlers with or at-risk for autism spectrum disorder / Stacy S. MANWARING in Autism & Developmental Language Impairments, 3 (January-December 2018)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 3 (January-December 2018) Titre : A scoping review of deictic gesture use in toddlers with or at-risk for autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Stacy S. MANWARING, Auteur ; Ashley L. STEVENS, Auteur ; Alfred MOWDOOD, Auteur ; Mellanye LACKEY, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background and aimsYoung children use deictic gestures, such as pointing, to indicate referents in their immediate environment. Early deictic gesture use is important in facilitating the development of language. In toddlers with or at-risk for autism spectrum disorder, the emergence and use of gestures may be delayed, and deficits in deictic gesture may inform clinical practice regarding early identification, differential diagnosis, and early intervention. The aim of this scoping review was to investigate the extent to which deictic gesture use has been examined in young children with or at-risk for autism spectrum disorder???36 months of age.MethodsFour databases (PubMed, PsycINFO, CINAHL, and ERIC) were comprehensively searched for relevant articles. Articles were reviewed in two phases: titles and abstracts followed by full text. Key variables related to participant/study characteristics and group differences on deictic gesture use were extracted. A narrative review was used to synthesize findings across studies.Main contributionNineteen studies met inclusion criteria ? 12 studies of toddlers with autism spectrum disorder and 7 studies of high-risk infant siblings of children diagnosed with autism spectrum disorder. Overall, toddlers with autism spectrum disorder were found to demonstrate reduced gesture use across deictic gesture types and ages compared to those with typical development. Findings were more variable when comparing toddlers with autism spectrum disorder to those with other developmental delays and in high-risk infant sibling studies. Although only measured in a limited number of studies, results suggest differences in gesture use in toddlers with autism spectrum disorder based on communicative function.ConclusionsThis review provides insight into the gesture use of toddlers with or at-risk for autism spectrum disorder. Results indicate the particular types of deictic gestures that may be delayed and the age ranges we might expect to observe these deficits in toddlers with autism spectrum disorder compared to those with typical development and other developmental delay groups. Results also reveal variability across studies in the measurement of gestures, and highlight where gaps remain in understanding deictic gesture use in young children with autism spectrum disorder.ImplicationsFindings have research and clinical implications related to profiling and targeting gesture use as part of the assessment and treatment process, including identifying patterns of strength and weakness in deictic gesture use of young children with or at-risk for autism spectrum disorder.

Speech-Language Pathology / Stacy S. MANWARING

Public ISBD in Handbook of Interdisciplinary Treatments for Autism Spectrum Disorder / Robert D. RIESKE Titre : Speech-Language Pathology Type de document : Texte imprimé et/ou numérique Auteurs : Stacy S. MANWARING, Auteur ; Angela B. BARBER, Auteur Année de publication : 2019 Importance : p.225-257 Langues : Anglais (eng) Index. décimale : AUT-F AUT-F - L'Autisme - Soins Résumé : Deficits in social communication and language are a primary component of ASD, with the majority of individuals requiring treatment in these areas. Communication delays are often the first concern parents notice in their children who are later diagnosed with ASD, and therefore, the speech-language pathologist (SLP) is often the first referral source. Selecting an appropriate intervention approach, matched to a child’s symptom profile and familial needs, is critical and can be challenging given the growing number of interventions available. Interventions that vary in theoretical framework and strength of empirical support have been developed to target the core deficits of ASD. This chapter provides an overview of interventions and practices aimed at improving communication and language skills in ASD. Naturalistic developmental behavioral interventions (NDBIs) are informed by both behavioral and developmental principles and incorporate the strengths of both perspectives. These interventions, which include comprehensive treatment programs as well as more focused intervention practices, have shown particularly positive effects on language and communication outcomes of young children with ASD. Common features and specific examples of NDBIs are described, highlighting the role of the SLP in implementing these interventions. In addition, focused intervention practices commonly used by SLPs, in conjunction with other treatments or within comprehensive treatment programs, are discussed, with a summary of empirical support provided.

Index. décimale : PER Périodiques Résumé : There is a critical need for accurate screening tools for autism spectrum disorder in very young children so families can access tailored intervention services as early as possible. However, there are few screeners designed for children 18-24months. Developing screeners that pick up on the signs of autism spectrum disorder in very young children has proved even more challenging. In this study, we examined a new autism-specific parent-report screening tool, the Early Screening for Autism and Communication Disorders for children between 12 and 36months of age. Field-testing was done in five sites with 471 children screened for communication delays in primary care or referred for familial risk or concern for autism spectrum disorder. The Early Screening for Autism and Communication Disorders was tested in three age groups: 12-17, 18-23, and 24-36months. A best-estimate diagnosis of autism spectrum disorder, developmental delay, or typical development was made. Analyses examined all 46 items and identified 30 items that best discriminated autism spectrum disorder from the non-spectrum groups. Cutoffs were established for each age group with good sensitivity and specificity. Results provide preliminary support for the accuracy of the Early Screening for Autism and Communication Disorders as an autism-specific screener in children 12-36months with elevated risk of communication delay or autism spectrum disorder.
