Participants were classified into one of the following groups, based on parent report using the Autism Diagnostic Interview—Revised: Early Onset (symptoms by 12 months, no loss), Delay + Regression (symptoms by 12 months plus loss), Plateau (no early symptoms or loss), and Regression (no early symptoms, followed by loss). Findings indicate that current functioning does not differ according to onset pattern, calling into question the use of onset categorizations for prognostic purposes in children with ASD.

Multisite Study of New Autism Diagnostic Interview-Revised (ADI-R) Algorithms for Toddlers and Young Preschoolers / So Hyun KIM in Journal of Autism and Developmental Disorders, 43-7 (July 2013)

Sensitivities and specificities and a three-factor solution were replicated. Results suggest that the new ADI-R algorithms can be appropriately applied to existing research databases with children from 12 to 47 months and down to nonverbal mental ages of 10 months for diagnostic grouping.

Repetitive Behavior and Restricted Interests in Young Children with Autism: Comparisons with Controls and Stability Over 2 Years / Lisa JOSEPH in Autism Research, 6-6 (December 2013)  

Public ISBD [article]  inAutism Research > 6-6 (December 2013) . - p.584-595 Titre : Repetitive Behavior and Restricted Interests in Young Children with Autism: Comparisons with Controls and Stability Over 2 Years Type de document : Texte imprimé et/ou numérique Auteurs : Lisa JOSEPH, Auteur ; Audrey THURM, Auteur ; Cristan A. FARMER, Auteur ; Stacy SHUMWAY, Auteur Année de publication : 2013 Article en page(s) : p.584-595 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  repetitive behaviors  young children  trajectory Index. décimale : PER Périodiques Résumé : Restricted, repetitive and stereotyped patterns of behavior, interests and activities [RRBs] are among the core symptoms of autism spectrum disorders (ASD). Previous studies have indicated that RRBs differentiate ASD from other developmental disorders and from typical development. This study examined the presentation of RRBs as reported on the Repetitive Behavior Scale-Revised, a caregiver report, in children with ASD [separated into autism and Pervasive Developmental Disorder-Not Otherwise Specified groups] compared with children with nonspectrum developmental delays or typical development. We examined the role of age, cognitive functioning, sex and social communication impairment as they relate to RRBs. The stability of RRBs in children with autism was also examined over the course of 2 years. Results of the study confirmed that the amount and type of RRBs differs by diagnosis. Age, cognitive functioning, sex and social-communication impairment were not significant correlates. Among children with autism, RRBs remained stable over time.

Social Communication Profiles of Children with Autism Spectrum Disorders Late in the Second Year of Life / Amy M. WETHERBY in Journal of Autism and Developmental Disorders, 37-5 (May 2007)

WETHERBY, Auteur ; Nola WATT, Auteur ; Lindee MORGAN, Auteur ; Stacy SHUMWAY, Auteur Année de publication : 2007 Article en page(s) : p.960-975 Langues : Anglais (eng) Mots-clés : Autism ASD Social-communication Early-identification Joint-attention Index. décimale : PER Périodiques Résumé : This study examined social communication profiles from behavior samples videotaped between 18 and 24 months of age in three groups of children: 50 with autism spectrum disorders (ASD), 23 with developmental delays (DD), and 50 with typical development (TD). The ASD group scored significantly lower than the DD group on 5 social communication measures and the TD group on all 14 measures, indicating distinct profiles late in the second year. Understanding was the strongest predictor of developmental level and behavior regulation and inventory of gestures were the strongest predictors of autism symptoms at 3 years of age. The predictive relations suggest five pivotal skills late in the second year that have a cascading effect on outcomes of children with ASD.

The ADOS Calibrated Severity Score: Relationship to Phenotypic Variables and Stability over Time / Stacy SHUMWAY in Autism Research, 5-4 (August 2012)  

Public ISBD [article]  inAutism Research > 5-4 (August 2012) . - p.267-76 Titre : The ADOS Calibrated Severity Score: Relationship to Phenotypic Variables and Stability over Time Type de document : Texte imprimé et/ou numérique Auteurs : Stacy SHUMWAY, Auteur ; Cristan A. FARMER, Auteur ; Audrey THURM, Auteur ; Lisa JOSEPH, Auteur ; David O. BLACK, Auteur ; Christine GOLDEN, Auteur Année de publication : 2012 Article en page(s) : p.267-76 Langues : Anglais (eng) Mots-clés : autism diagnostic observation schedule (ADOS)  autism spectrum disorders  severity  diagnosis Index. décimale : PER Périodiques Résumé : Measurement of the severity of autism at a single time point, and over time, is a widespread challenge for researchers. Recently, Gotham, Pickles, and Lord published a severity metric (calibrated severity scores; CSS) that takes into account age and language level and is based on raw total scores of the Autism Diagnostic Observation Schedule (ADOS), a standardized measure commonly used in autism diagnosis. The present study examined psychometric characteristics of the CSS compared to raw scores in an independent sample of 368 children aged 2 to 12 years with autism, pervasive developmental disorder-not otherwise specified (PDD-NOS), non-spectrum delay, or typical development. Reflecting the intended calibration, the CSS were more uniformly distributed within clinical diagnostic category and across ADOS modules than were raw scores. Cross-sectional analyses examining raw and severity scores and their relationships to participant characteristics revealed that verbal developmental level was a significant predictor of raw score but accounted for significantly less variance in the CSS. Longitudinal analyses indicated overall stability of the CSS over 12 to 24 months in children with autism. Findings from this study support the use of the CSS as a more valid indicator of autism severity than the ADOS raw total score, and extend the literature by examining the stability over 12 to 24 months of the CSS in children with ASD.
