Data from ADOS-2 administrations (Modules 1, 2, 3) were collected from 3364 children (mean age = 6.73 years) at an outpatient ASD clinic. For those with ASD, ADOS-2 Calibrated Severity Scores (CSS) were descriptively higher for those with overactivity and disruptive behavior, but lower for those with anxiety. For those without ASD, no patterns emerged when comparing means. After controlling for age, sex, and language level, multivariable linear models indicated the presence of overactivity was significantly associated with increased CSS for children with ASD compared to those without. No significant interaction was present for disruptive behavior. The presence of anxiety was significantly associated with increased Social Affect CSS only for those without ASD. All effect sizes were small. This is one of the first studies to evaluate the effect of each individual E code on ADOS-2 CSS. Unique differences emerged across diagnostic groups, suggesting implications for ADOS-2 interpretation.Lay Summary The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is a common assessment tool used during an autism evaluation. As part of the ADOS-2, the examiner rates “E codes,” which are levels of hyperactivity, disruptive behavior, and anxiety during testing. These codes are not part of the final ADOS-2 score. While there is a lot of research on the ADOS-2, less is known about these E codes. This study looked at how the E codes might affect the final ADOS-2 scoring. Information came from 3364 in-person autism assessments (average age = 6.73 years) who were evaluated at an autism specialty clinic. For autistic children, ADOS-2 scores were higher (i.e. more autism-related behaviors) for those with overactivity and disruptive behavior, but lower for those with anxiety. For those without autism, there was no pattern. After accounting for the child’s age, sex, and language level, there were unique results for each E code, depending on whether the child received an autism diagnosis. This study is important as it is one of the first to evaluate the effects of each E code on ADOS-2 scores and could impact how scores are interpreted when considering an autism diagnosis.

Brief Report: Sex Differences in Parental Concerns for Toddlers with Autism Risk / Riane K. RAMSEY in Journal of Autism and Developmental Disorders, 48-12 (December 2018)

The current study examined whether sex and diagnosis relate to the timing, number, and types of pre-diagnosis concerns for 669 (Nmale = 468) toddlers who screened at risk for ASD. No sex differences in parents' concerns emerged for toddlers diagnosed with ASD; however, in the overall at-risk sample, parents of boys endorsed ASD symptoms, including restricted and repetitive behaviors, more than parents of girls. Future research should examine why sex differences in pre-diagnosis concerns emerge and how they might impact early diagnosis for at-risk boys versus girls.

Cortical Vision Impairment (CVI)-informed assessment and treatment of challenging behavior in a child with SCN2A-related disorder / Benjamin R. THOMAS in Journal of Neurodevelopmental Disorders, 16 (2024)

Index. décimale : PER Périodiques Résumé : This report presents results of parent-implemented behavioral treatments for a child with cortical visual impairment (CVI), intellectual disability (ID), epilepsy, and autism spectrum disorder (ASD) associated with a pathogenic variant in the SCN2A gene (i.e., SCN2A-Related Disorder). Treatment evaluations were informed by combined results of functional behavior assessment (FBA) and functional vision assessment (FVA) which yielded CVI-related accommodations. The treatment of escape-maintained challenging behavior involved the evaluation of behavioral prompting strategies in accordance with CVI-related accommodations, extinction (EXT), and differential reinforcement modifications. The treatment for behavior problems maintained by access to food (tangible-edible) included functional communication training (FCT), EXT, and schedule thinning with schedule-correlated visual signals. Overall, integrating child-specific CVI-related accommodations was essential for developing effective behavioral interventions for this child. FVAs are accessible and practical for uptake by behavior analysts in vision-informed assessment and treatment of challenging behavior.

Prevalence of gastrointestinal symptoms among autistic individuals, with and without co-occurring intellectual disability / Calliope HOLINGUE in Autism Research, 16-8 (August 2023)  

Public ISBD [article]  inAutism Research > 16-8 (August 2023) . - p.1609-1618 Titre : Prevalence of gastrointestinal symptoms among autistic individuals, with and without co-occurring intellectual disability Type de document : texte imprimé Auteurs : Calliope HOLINGUE, Auteur ; Danika PFEIFFER, Auteur ; Natasha N.

KALB, Auteur ; Rebecca LANDA, Auteur Article en page(s) : p.1609-1618 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Gastrointestinal symptoms (GI) are very common among individuals on the autism spectrum. Prior research reports mixed findings regarding whether individuals with autism and co-occurring intellectual disability (ID) have elevated risk of gastrointestinal symptoms relative to individuals with autism alone. GI symptoms can be challenging to assess in individuals with autism spectrum disorder (ASD) and/or ID given challenges with language, communication, and interoception. Prior research has tended to only include individuals with documented presence or absence of GI symptoms or conditions, that is, to exclude observations in which there is uncertainty regarding presence of GI symptoms. Therefore, none of the prior autism studies reported the association between ID and the certainty regarding presence or absence of GI symptoms. The objective of this study was to examine differences in parental certainty and odds of reporting gastrointestinal signs and symptoms among children on the autism spectrum, with and without intellectual disability. Participants were 308 children (36% ID) with a clinical diagnosis of autism spectrum disorder (6-17 years). Parents endorsed whether their child had experienced or displayed a range of signs or symptoms related to GI problems in the past 3 months. Parents of autistic children with ID were less certain about the presence of more subjective symptoms, including abdominal pain, nausea, and bloating. Conversely, certainty regarding more objective signs (e.g., constipation, diarrhea, spitting up, etc.) was not significantly different. More accurate measures for GI signs/symptoms are needed for this population.

Replication study for ADOS-2 cut-offs to assist evaluation of autism spectrum disorder / Ji Su HONG in Autism Research, 15-11 (November 2022)

While prior studies investigated sensitivity and specificity of ADOS-2 Modules 1-3, there has been limited research addressing algorithm cut-off scores to optimize ADOS-2 classification. The goal of this study was to assess algorithm cut-off scores for diagnosing ASD with Modules 1-3, and to evaluate alignment of the ADOS-2 classification with the best estimate clinical diagnosis. Participants included 3144 children aged 31 months or older who received ADOS-2 Modules 1-3, as well as the best estimate clinical diagnosis. Five classification statistics were reported for each module: sensitivity, specificity, positive predictive value, negative predictive value, and accuracy (i.e., Receiver Operator Classification Statistic), and these statistics were calculated for the optimal cut-off score. Frequency tables were used to compare ADOS-2 classification and the best estimate clinical diagnosis. Half of the sample received Module 3, 21% received Module 2, and 29% received Module 1. The overall prevalence of ASD was 60%; the male-to-female ratio was 4:1, and half of the sample was non-White. Across all modules, the autism spectrum cut-off score from the ADOS-2 manual resulted in high sensitivity (95%+) and low specificity (63%-73%). The autism cut-off score resulted in better specificity (76%-86%) with favorable sensitivity (81%-94%). The optimal cut-off scores for all modules based on the current sample were within the autism spectrum classification range except Module 2 Algorithm 2. In the No ASD group, 29% had false positives (ADOS-2 autism spectrum classification or autism classification). The ADOS-2 autism spectrum classification did not indicate directionality for diagnostic outcome (ASD 56% vs. No ASD 44%). While cut-off scores of ADOS-2 Modules 1-3 in the manual yielded good clinical utility in ASD assessment, false positives and low predictability of the autism spectrum classification remain challenging for clinicians.
