Effectiveness of Using the Modified Checklist for Autism in Toddlers in Two-Stage Screening of Autism Spectrum Disorder at the 18-Month Health Check-Up in Japan / Yoko KAMIO in Journal of Autism and Developmental Disorders, 44-1 (January 2014)

Two-stage screening using the M-CHAT was conducted with 1,851 children attending the check-up. Final ASD diagnosis was confirmed at age ?3 years. Screening identified 20/51 children with ASD: 12/20 true positives were developmentally delayed, whereas 16/22 false negatives were high-functioning. Sensitivity was 0.476, specificity 0.986, positive predictive value 0.455, and likelihood ratio 33.4 for children with ASD. With a few modifications, M-CHAT screening successfully detected toddlers with ASD with and without developmental delay and is a promising screening tool to complement existing community surveillance.

Maternal age at childbirth and social development in infancy / Tomonori KOYAMA in Research in Autism Spectrum Disorders, 5-1 (January-March 2011)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 5-1 (January-March 2011) . - p.450-454 Titre : Maternal age at childbirth and social development in infancy Type de document : Texte imprimé et/ou numérique Auteurs : Tomonori KOYAMA, Auteur ; Yoko KAMIO, Auteur ; Naoko INADA, Auteur ; Eiko INOKUCHI, Auteur Année de publication : 2011 Article en page(s) : p.450-454 Langues : Anglais (eng) Mots-clés : Autism-spectrum-disorders-(ASD) Maternal-age Modified-Checklist-for-Autism-in-Toddlers-(M-CHAT) Social-development Index. décimale : PER Périodiques Résumé : Difficulties in social communication are not necessarily observed only in individuals with autism spectrum disorders (ASD), and there are many subclinical cases in the general populations. Although advanced parental age at childbirth has often been considered a possible risk factor of ASD, it might contribute to poor social functioning in children, rather than to ASD itself. This study examined whether advanced maternal age at childbirth and obstetric factors were associated with atypical social development in infancy. At free health check-ups for children aged 18 months conducted in Munakata city, Japan, 1460 children (729 males) were assessed using the Japanese version of the Modified Checklist for Autism in Toddlers (M-CHAT). Adjusted odds ratio showed that children of mothers aged ≥35 years at childbirth were 2.22 (95% confidence intervals, 1.39–3.55) times more likely to fail on the M-CHAT (failing three or more items) compared with the reference group (aged ≤29). Although most mothers will have toddlers that fall in the typical range on this measure of social development, clinicians should pay more attention to early social development of children, especially for lateborn babies, and should be more sensitive to their potential needs so as to provide appropriate advice and support for their caregivers.

Qualitative analyses of verbal fluency in adolescents and young adults with high-functioning autism spectrum disorder / Eiko INOKUCHI in Research in Autism Spectrum Disorders, 7-11 (November 2013)

In this study, we compared through qualitative and quantitative analyses performance on letter fluency (LF), category fluency (CF), and action fluency (AF) in adolescents and young adults with high-functioning autism spectrum disorders (HFASD) with that of an age-, gender-, and IQ-matched control group. Quantitative analyses revealed significantly fewer correct responses on category and action fluency and significantly more intrusions on category fluency in individuals with HFASD than in control participants. Qualitative analyses revealed significantly fewer semantic clusters and significantly more phonemic clusters during action fluency in individuals with HFASD compared to control participants. With respect to action fluency, the number of correct responses and clusters were related to verbal IQ for individuals with HFASD but not for control participants. We discuss these results in terms of abnormalities in semantic/phonemic strategy choice, cognitive flexibility, and generativity in ASD.

Subsequently, to assess the discriminant and diagnostic validity of ADI-R-JV, the authors investigated 317 individuals aged 2–19 years, who were divided into three diagnostic groups as follows: autistic disorder (AD), pervasive developmental disorder not otherwise specified, and other psychiatric diagnosis or no diagnosis, according to the consensus clinical diagnosis. As regards inter-rater reliability, intraclass correlation coefficients of greater than 0.80 were obtained for all three domains of ADI-R-JV. As regards discriminant validity, the mean scores of the three domains was significantly higher in individuals with AD than in those of other diagnostic groups. As regards diagnostic validity, sensitivity and specificity for correctly diagnosing AD were 0.92 and 0.89, respectively, but sensitivity was 0.55 for individuals younger than 5 years. Specificity was consistently high regardless of age and intelligence. ADI-R-JV was shown to be a reliable tool, and has sufficient discriminant validity and satisfactory diagnostic validity for correctly diagnosing AD, although the diagnostic validity appeared to be compromised with respect to the diagnosis of younger individuals.

Reliability and validity of the Japanese version of the Modified Checklist for autism in toddlers (M-CHAT) / Naoko INADA in Research in Autism Spectrum Disorders, 5-1 (January-March 2011)

Therefore, we examined the reliability and validity of the Japanese version of the Modified Checklist for autism in toddlers (M-CHAT), a 23-item, yes–no questionnaire regarding early autistic symptoms completed by parents of children at 18–24 months of age. Herein, the reliability of the M-CHAT was investigated for children 4–20 months of age. The M-CHAT score (the number of failed items) was found to be significantly correlated among 24 mother–father pairs (Pearson's r = .933), representing good inter-rater reliability. The test–retest reliability was satisfactory, with 22 mothers providing almost equal M-CHAT scores on two different occasions (r = .990). Significant correlations were observed between the M-CHAT score and the Childhood Autism Rating Scale-Tokyo version score in 25 two-year-old children (r = .581), indicating good concurrent validity. The M-CHAT score was significantly higher in 20 children later diagnosed with ASD compared with reference children (n = 1167), revealing sufficient discriminant validity. A short version of the M-CHAT using 9 items was proposed and effectively differentiated children with ASD from reference children. The efficacy of the Japanese version of the M-CHAT was demonstrated for first-level screening in the general population.
