Mean age of the children at time of diagnosis was 3 years 10 months. Of the 202 children diagnosed with ASD on the DSM-IV-TR, 184 (91.1 %) also met the DSM-5 criteria for ASD. The overall concordance rate of ASD diagnosis on the DSM-IV-TR and DSM-5 was higher than that reported in other studies. Of the 18 children who did not meet DSM-5 criteria for ASD, 16 children met all social communication criteria but did not fulfil at least two restricted and repetitive behaviour (RRB) criteria. Six of those children had further RRBs emerging later on follow-up.

A Direct Comparison of Three Screening Methods for Autism Spectrum Disorder in a High-Likelihood Sibling Population / Chui Mae WONG in Journal of Autism and Developmental Disorders, 55-4 (April 2024)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 55-4 (April 2024) . - p.1274-1285 Titre : A Direct Comparison of Three Screening Methods for Autism Spectrum Disorder in a High-Likelihood Sibling Population Type de document : Texte imprimé et/ou numérique Auteurs : Chui Mae WONG, Auteur ; Nurhafizah MOHD ZAMBRI, Auteur ; Hui Hua FAN, Auteur ; Lily H. S. LAU, Auteur ; L. Mary DANIEL, Auteur ; Hwan Cui KOH, Auteur Article en page(s) : p.1274-1285 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Targeted screening of children at increased likelihood of autism is recommended. However, autism screening tools are usually validated for use mainly in low-likelihood populations. This study compared the accuracy of the Modified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F), the ASDetect app, and the Social Attention and Communication Surveillance, Revised (SACS-R). Siblings of autistic children underwent autism screening at 12, 18 and 30 months old. At each visit, caregivers completed the M-CHAT-R/F and ASDetect while trained nurses tested the siblings using the SACS-R. At 36 to 48 months, the siblings underwent an Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) assessment. 189 siblings were screened, 141 completed the study, and 32 were confirmed to have autism. Although not validated for use at 12 months, the M-CHAT-R/F had the best sensitivity among the three tools for this age group, suggesting that early signs are already apparent to caregivers. The M-CHAT-R/F had overall better sensitivity (0.72-0.83) across all age groups, but with overall lower specificity (0.55-0.77). The SACS-R and ASDetect had better positive predictive values at 18 and 30 months (0.60-0.68), while the M-CHAT-R/F was 0.43-0.48. Negative predictive values were generally high across all three tools across all age groups (0.78-0.93). Targeted screening of children at high likelihood of autism yielded a detection rate of 22.7% and should therefore be implemented routinely to facilitate early detection and intervention. The performance of autism screening tools should be examined in higher-likelihood populations for targeted screening of these children.

The Clinical Utility of the Modified Checklist for Autism in Toddlers with High Risk 18–48 Month Old Children in Singapore / Hwan Cui KOH in Journal of Autism and Developmental Disorders, 44-2 (February 2014)

It is a well-researched tool, but little is known about its utility with Singaporean toddlers and with older children referred for developmental concerns. This study investigated the M-CHAT’s performance with 18–30 month old (N = 173) and 30–48 month old (N = 407) developmentally at-risk Singaporean children, when used with three recommended scoring methods i.e., the total, critical and Best7 scoring methods. The results indicate that the critical and Best7 scoring methods detected most true cases of ASD without inflating the false positive rates in toddlers, and that only the total scoring method performed acceptably for the older children.
