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

Titre : Parent-reported and clinician-observed autism spectrum disorder (ASD) symptoms in children with attention deficit/hyperactivity disorder (ADHD): implications for practice under DSM-5 Type de document : Texte imprimé et/ou numérique Auteurs : R. GRZADZINSKI, Auteur ; C. DICK, Auteur ; C. LORD, Auteur ; Somer L. BISHOP, Auteur Article en page(s) : 7p. Langues : Anglais (eng) Mots-clés : Adolescent Age of Onset Attention Deficit Disorder with Hyperactivity/diagnosis Autism Spectrum Disorder/diagnosis Child Child, Preschool Diagnosis, Differential Diagnostic and Statistical Manual of Mental Disorders Facial Expression Female Fixation, Ocular Humans Interview, Psychological Male Observer Variation Parents/psychology Psychiatry Psychological Tests Psychology Severity of Illness Index Social Behavior Symptom Assessment Attention Deficit/Hyperactivity Disorder (ADHD) Autism Autism Diagnostic Interview-Revised (ADI-R) Autism Diagnostic Observation Schedule (ADOS) Autism Spectrum Disorder (ASD) Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Index. décimale : PER Périodiques Résumé : BACKGROUND: Children with attention deficit/hyperactivity disorder (ADHD) often present with social difficulties, though the extent to which these clearly overlap with symptoms of autism spectrum disorder (ASD) is not well understood. METHODS: We explored parent-reported and directly-observed ASD symptoms on the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) in children referred to ASD-specialty clinics who received diagnoses of either ADHD (n = 48) or ASD (n = 164). RESULTS: Of the ADHD sample, 21 % met ASD cut-offs on the ADOS and 30 % met ASD cut-offs on all domains of the ADI-R. Four social communication ADOS items (Quality of Social Overtures, Unusual Eye Contact, Facial Expressions Directed to Examiner, and Amount of Reciprocal Social Communication) adequately differentiated the groups while none of the items on the ADI-R met the criteria for adequate discrimination. CONCLUSIONS: Results of this work highlight the challenges that clinicians and researchers face when distinguishing ASD from other disorders in verbally fluent, school-age children.

It is unclear, however, if high-functioning individuals deemed eligible for research via standardized diagnostic assessments would meet DSM-5 criteria. This study investigated the impact of DSM-5 on the diagnostic status of 498 high-functioning participants with ASD research diagnoses. The percent of participants satisfying all DSM-5-requirements varied significantly with reliance on data from the Autism Diagnostic Observation Schedule (ADOS; 33 %) versus Autism Diagnostic Interview-Revised (ADI-R; 83 %), highlighting the impact of diagnostic methodology on ability to document DSM-5 symptoms. Utilizing combined ADOS/ADI-R data, 93 % of participants met DSM-5 criteria, which suggests likely continuity between DSM-IV and DSM-5 research samples characterized with these instruments in combination.

The BOSCC coding scheme is applied to 177 video observations of 56 young children with ASD and minimal language abilities. The BOSCC has high to excellent inter-rater and test–retest reliability and shows convergent validity with measures of language and communication skills. The BOSCC Core total demonstrates statistically significant amounts of change over time compared to a no change alternative while the ADOS CSS over the same period of time did not. This work is a first step in the development of a novel outcome measure for social-communication behaviors with applications to clinical trials and longitudinal studies.

We also compare the level of autistic traits, social perception skills and obsessive–compulsive symptoms in four groups: AN, ASD, and two gender- and age-matched control groups. Of the 30 AN participants, only three scored above the conventional ADOS-2 threshold for ASD. The AN participants were similar to their controls on autistic trait measures, and to the ASD group on obsessive–compulsive measures, and on theory of mind ability and affect recognition measures. Further longitudinal studies are needed in order to determine the association between these conditions.
