We examined the characteristics of dysregulation in children presenting to a multidisciplinary ASD clinic for an ASD diagnostic evaluation. Sixty percent of children presenting for an ASD evaluation exhibited dysregulation. Dysregulation prevalence was higher in children without ASD versus with ASD (69% versus 56%). Severe dysregulation was higher in children without ASD (29% versus 16%). Both groups with severe dysregulation were equally likely to be taking psychiatric medications, however, children with ASD were less likely to be receiving therapy. These findings highlight the importance of implementing dysregulation screening and treatment protocols in ASD centers.

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 et/ou numérique Auteurs : Calliope HOLINGUE, Auteur ; Danika PFEIFFER, Auteur ; Natasha N. LUDWIG, Auteur ; Rachel REETZKE, Auteur ; Ji Su HONG, Auteur ; Luther G. 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.

Psychometric Evaluation of the Autism Spectrum Rating Scales (6-18 Years Parent Report) in a Clinical Sample / Ji Su HONG in Journal of Autism and Developmental Disorders, 54-3 (March 2024)

Several screening measures have been developed for early identification, including the Autism Spectrum Rating Scales, 6-18 years Parent Report (ASRS). The ASRS has been understudied, and the current study assessed the validity of the ASRS in a clinical sample of 490 children at a tertiary ASD-specialty clinic. Results indicated that the ASRS demonstrated favorable sensitivity, but poor specificity. True positive screening results were more likely to occur for children with a multiracial background, while they were less likely to occur for children with a high social capital. Overall, though the ASRS has clinical utility as a screening measure, it did not perform effectively to differentiate ASD from Non-ASD clinical disorders.

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.
