Definitions of Nonverbal and Minimally Verbal in Research for Autism: A Systematic Review of the Literature / Lynn KERN KOEGEL in Journal of Autism and Developmental Disorders, 50-8 (August 2020)

Titre : Definitions of Nonverbal and Minimally Verbal in Research for Autism: A Systematic Review of the Literature Type de document : Texte imprimé et/ou numérique Auteurs : Lynn KERN KOEGEL, Auteur ; Katherine M. BRYAN, Auteur ; Pumpki L. SU, Auteur ; Mohini VAIDYA, Auteur ; Stephen M. CAMARATA, Auteur Article en page(s) : p.2957-2972 Langues : Anglais (eng) Mots-clés : Autism Communication treatment Expressive words Minimally verbal Nonverbal authors have no conflicts of interest to report. Index. décimale : PER Périodiques Résumé : This systematic review examined definitions of "nonverbal" or "minimally verbal" and assessment measures used to evaluate communication in intervention studies focusing on improving expressive verbal communication in children with autism spectrum disorder (ASD). We reviewed sample size, number of participants, participant age, and male/female representation. Our analysis yielded relatively few studies with non/minimally verbal children with ASD focusing on verbal expressive communication. Further, we found large inconsistencies in measures used, definitions of "nonverbal" and "minimally verbal", and ages targeted. Guidelines are suggested to create a more uniform assessment protocol with systematic descriptions of early communication learners as a foundational step for understanding the heterogeneity in this group and replicating research findings for this subgroup of children with ASD.

Langues : Anglais (eng) Mots-clés : Auditory cortex Autism spectrum disorder M50/M100 responses and language impairment Magnetoencephalography Minimally verbal/non-verbal children Nonverbal Index. décimale : PER Périodiques Résumé : Abnormal auditory neuromagnetic M50 and M100 responses, reflecting primary/secondary auditory cortex processing, have been reported in children who have autism spectrum disorder (ASD). Some studies have reported an association between delays in these responses and language impairment. However, as most prior research has focused on verbal individuals with ASD without cognitive impairment, rather little is known about neural activity during auditory processing in minimally verbal or nonverbal children who have ASD (ASD-MVNV)-children with little or no speech and often significant cognitive impairment. To understand the neurophysiological mechanisms underlying auditory processing in ASD-MVNV children, magnetoencephalography (MEG) measured M50 and M100 responses arising from left and right superior temporal gyri during tone stimuli in three cohorts: (1) MVNV children who have ASD (ASD-MVNV), (2) verbal children who have ASD and no intellectual disability (ASD-V), and (3) typically developing (TD) children. One hundred and five participants (8-12 years) were included in the final analyses (ASD-MVNV: n = 16, 9.85 +/- 1.32 years; ASD-V: n = 55, 10.64 +/- 1.31 years; TD: n = 34, 10.18 +/- 1.36 years). ASD-MVNV children showed significantly delayed M50 and M100 latencies compared to TD. These delays tended to be greater than the corresponding delays in verbal children with ASD. Across cohorts, delayed latencies were associated with language and communication skills, assessed by the Vineland Adaptive Behavior Scale Communication Domain. Findings suggest that auditory cortex neural activity measures could be dimensional objective indices of language impairment in ASD for either diagnostic (e.g., via threshold or cutoff) or prognostic (considering the continuous variable) use.

Titre : Improving Pragmatics in Nonverbal Children with Autism Using Melodic Based Communication Therapy Type de document : Texte imprimé et/ou numérique Auteurs : Givona A. SANDIFORD, Auteur ; Karen J. MAINESS, Auteur ; Noha S. DAHER, Auteur Année de publication : 2013 Article en page(s) : 5 p. Langues : Anglais (eng) Mots-clés : Autism Pragmatics Social skills Music Speech therapy Nonverbal Index. décimale : PER Périodiques Résumé : Background of study: Persistent deficits in social communication and social interaction are key components in the diagnosis of autism. For this reason it is clear that successful intervention for individuals with autism must address this deficit. Melodic Based Communication Therapy (M.B.C.T) has been previously found to improve expressive vocabulary and verbal imitative abilities in nonverbal individuals with autism over the age of 5; however findings on the effect of M.B.C.T. on pragmatic (social) language have not previously been discussed. Purpose: The objective of this study was to examine the effect of 5 consecutive weeks of Melodic Based Communication Therapy on pragmatics in nonverbal children with autism. Method: Participants were 12 nonverbal children with autism ages 5 through 7 randomly assigned to the M.B.C.T. or control group. Participants received 5 weeks of intervention, with four 45-minute individual sessions a week. The Pragmatic Language Skills Inventory (PLSI) was used to measure pragmatics pre and post treatment. Results: Following treatment, the M.B.C.T. group showed significant improvement in PLSI score (72.3 ± 10.1 vs 65.4 ± 7.0, p=.04) while the control group did not (67.7 ± 1.2 vs 66.8 ±.5, p=.32). However, there was no significant difference in improvement between the two groups (6.9 ± 2.4 vs 1.0 ±.5, p=.11). Conclusions: Results suggest M.B.C.T. may be a viable means of improving pragmatics in children with autism over time. However, a larger sample size may be needed for more conclusive results.

Participants were 12 nonverbal children with autism ages 5 through 7 randomly assigned to either treatment group. Both groups made significant progress after treatment. The MBCT group progressed significantly in number of verbal attempts after weeks 1 through 4 and number of correct words after weeks 1 and 3, while the traditional group progressed significantly after weeks 4 and 5. No significant differences in number of verbal attempts or number of correct words were noted between groups following treatment. A significant number of new words were heard in the home environment for the MBCT group (p = .04). Participants in the MBCT group had more imitative attempts (p = .03). MBCT appears to be a valid form of intervention for children with autism.

Statistical models that accounted for the intercorrelation among nine theoretically- and empirically-motivated predictors, as well as two background variables (i.e., cognitive impairment level, autism severity), were applied to identify value-added predictors of expressive and receptive spoken language growth and outcome. The results indicate that responding to joint attention, intentional communication, and parent linguistic responses were value-added predictors of both expressive and receptive spoken language growth. In addition, consonant inventory was a value-added predictor of expressive growth; early receptive vocabulary and autism severity were value-added predictors of receptive growth.
