Interest level in 2-year-olds with autism spectrum disorder predicts rate of verbal, nonverbal, and adaptive skill acquisition / Lars KLINTWALL in Autism, 19-8 (November 2015) 

Public ISBD [article]  in Autism > 19-8 (November 2015) . - p.925-933 Titre : Interest level in 2-year-olds with autism spectrum disorder predicts rate of verbal, nonverbal, and adaptive skill acquisition Type de document : texte imprimé Auteurs : Lars KLINTWALL, Auteur ; Suzanne MACARI, Auteur ; Svein EIKESETH, Auteur ; Katarzyna CHAWARSKA, Auteur Article en page(s) : p.925-933 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  behavioral measurement  interventions—psychosocial/behavioral  development Index. décimale : PER Périodiques Résumé : Recent studies have suggested that skill acquisition rates for children with autism spectrum disorders receiving early interventions can be predicted by child motivation. We examined whether level of interest during an Autism Diagnostic Observation Schedule assessment at 2?years predicts subsequent rates of verbal, nonverbal, and adaptive skill acquisition to the age of 3?years. A total of 70 toddlers with autism spectrum disorder, mean age of 21.9?months, were scored using Interest Level Scoring for Autism, quantifying toddlers’ interest in toys, social routines, and activities that could serve as reinforcers in an intervention. Adaptive level and mental age were measured concurrently (Time 1) and again after a mean of 16.3?months of treatment (Time 2). Interest Level Scoring for Autism score, Autism Diagnostic Observation Schedule score, adaptive age equivalent, verbal and nonverbal mental age, and intensity of intervention were entered into regression models to predict rates of skill acquisition. Interest level at Time 1 predicted subsequent acquisition rate of adaptive skills (R2?=?0.36) and verbal mental age (R2?=?0.30), above and beyond the effects of Time 1 verbal and nonverbal mental ages and Autism Diagnostic Observation Schedule scores. Interest level at Time 1 also contributed (R2?=?0.30), with treatment intensity, to variance in development of nonverbal mental age.

Language outcomes of toddlers with autism spectrum disorders: a two year follow-up / Rhea PAUL in Autism Research, 1-2 (April 2008) 

Public ISBD [article]  in Autism Research > 1-2 (April 2008) . - p.97-107 Titre : Language outcomes of toddlers with autism spectrum disorders: a two year follow-up Type de document : texte imprimé Auteurs : Rhea PAUL, Auteur ; Fred R. VOLKMAR, Auteur ; Katarzyna CHAWARSKA, Auteur ; Domenic V. CICCHETTI, Auteur Article en page(s) : p.97-107 Langues : Anglais (eng) Mots-clés : autism language communication toddlers Index. décimale : PER Périodiques Résumé : Thirty-seven children 15-25 months of age received clinical diagnoses of autism spectrum disorder (ASD) and were re-evaluated two years later. All subjects were judged to have retained a diagnosis of ASD at the follow-up evaluation. Communication scores for the group as a whole during the first visit were significantly lower than nonverbal IQ. However, by the second visit, verbal and nonverbal scores were no longer significantly different. The group was divided into two subgroups, based on expressive language (EL) outcome at the second visit. The two groups were similar in the second year of life in terms of expressive communication skills and autistic symptoms, except for a trend toward more stereotypic and repetitive behavior in the worse outcome group. By the second visit, however, the groups differed significantly on all standard measures of expression and reception, as well as on autistic symptomotology and nonverbal IQ. When assessed during their second year, children who ended up in the better outcome group showed higher average nonverbal cognitive level, receptive language (RL) scores, number of sounds and words produced, use of symbolic play schemes, and response to joint attention bids. Regression analysis revealed that the variables for which significant differences between the two outcome groups in their second year of life were found provided significant prediction of EL outcome at age four. Stepwise regression identified RL and presence of stereotypic and repetitive at the first visit as significantly associated with EL outcome. Implications of these findings for early identification and intervention are discussed.

Looking But Not Seeing: Atypical Visual Scanning and Recognition of Faces in 2 and 4-Year-Old Children with Autism Spectrum Disorder / Katarzyna CHAWARSKA in Journal of Autism and Developmental Disorders, 39-12 (December 2009) 

Public ISBD [article]  in Journal of Autism and Developmental Disorders > 39-12 (December 2009) . - p.1663-1672 Titre : Looking But Not Seeing: Atypical Visual Scanning and Recognition of Faces in 2 and 4-Year-Old Children with Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Katarzyna CHAWARSKA, Auteur ; Frederick SHIC, Auteur Article en page(s) : p.1663-1672 Langues : Anglais (eng) Mots-clés : Autism ASD Face-scanning Face-recognition Toddlers Index. décimale : PER Périodiques Résumé : This study used eye-tracking to examine visual scanning and recognition of faces by 2- and 4-year-old children with autism spectrum disorder (ASD) (N = 44) and typically developing (TD) controls (N = 30). TD toddlers at both age levels scanned and recognized faces similarly. Toddlers with ASD looked increasingly away from faces with age, atypically attended to key features of faces, and were impaired in face recognition. Deficits in recognition were associated with imbalanced attention between key facial features. This study illustrates that face processing in ASD may be affected early and become further compromised with age. We propose that deficits in face processing likely impact the effectiveness of toddlers with ASD as social partners and thus should be targeted for intervention.

We report outcomes at age 3 years using the Mullen Scales of Early Learning, the Autism Diagnostic Observation Schedule (ADOS), the Autism Diagnostic Interview—Revised (ADI-R) and adaptive functioning on the Vineland Adaptive Behavior Scales. Around 11% of high-risk siblings had mild-to-moderate levels of developmental delay, a rate higher than the low-risk controls. The groups did not differ in the proportion of toddlers with mild-to-moderate language delay. Thirty percent of high-risk siblings had elevated scores on the ADOS, double the rate seen in the low-risk controls. High-risk siblings also had higher parent reported levels of ASD symptoms on the ADI-R and lower adaptive functioning on the Vineland. Males were more likely to show higher levels of ASD symptoms and lower levels of developmental ability and adaptive behavior than females across most measures but not mild-to-moderate language delay. Lower maternal education was associated with lower developmental and adaptive behavior outcomes. These findings are evidence for early emerging characteristics related to the “broader autism phenotype” (BAP) previously described in older family members of individuals with ASD. There is a need for ongoing clinical monitoring of high-risk siblings who do not have an ASD by age 3 years, as well as continued follow-up into school age to determine their developmental and behavioral outcomes.
