Developmental chronology of preverbal social behaviors in infancy using the M-CHAT: Baseline for early detection of atypical social development / Naoko INADA in Research in Autism Spectrum Disorders, 4-4 (October-December 2010)

This was accomplished using 16 items of social behaviors extracted from the Modified Checklist for Toddlers with Autism (M-CHAT). The Japanese version of the M-CHAT was completed voluntarily by the parents of 318 infants aged 8–20 months. The 16 social behaviors can be divided roughly into three behavior sets based on the age at which 75% of the answers to the corresponding items were positive: the first set of 6 items emerged before 8 month old; the second set of 6 items, did between 11 and 12 month old; and the third set of 4 items, did after 15 month old. In addition, the subsequent order and synchrony among items were determined: Imitation, Point following, and Attracting parent's attention emerged earlier than Pretend play and Imperative/Declarative pointing in the second set; further, Gaze following and Social reference emerged earlier than Bringing objects to show and Functional play in the third set. This study provides an evidence-based developmental chronology of a wide range of preverbal social behaviors, which can serve as a baseline for assessing atypical social development in infants.

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.

Mirroring effect in 2- and 3-year-olds with autism spectrum disorder / Masatoshi KATAGIRI in Research in Autism Spectrum Disorders, 4-3 (July-September 2010)

The purpose of this study wais to investigate whether “mirroring” interaction, which includes being imitated by an adult, can facilitate the social responsiveness of toddlers with autism spectrum disorder (ASD). Participants were 16 toddlers (2- and 3-year-olds) with ASD. This study consisted of three experimental phases: in the first baseline phase, the experimenter manipulated toys in front of the participant; in the second phase, the experimenter reproduced (mirrored) all of the child's behaviors; and in the third phase, the first baseline phase was repeated. Our results demonstrated that although the mirroring effect differed by age, the effect was observed in both 2- and 3-year-olds with ASD. In addition, the overall magnitude of the mirroring effect differed by IQ, but not by the severity of autistic symptoms. Mirroring interaction is promising as an early intervention for a wide range of children with ASD.

A nationwide survey on quality of life and associated factors of adults with high-functioning autism spectrum disorders / Yoko KAMIO in Autism, 17-1 (January 2013)

To identify predictive variables that are potentially ameliorable by therapeutic intervention, this study investigated self-reported psychosocial quality of life and associated factors for adults with HFASD. All participants (n = 154) had a diagnosis of autism spectrum disorder, were over 18 years of age, lived in the community, and had used one or more support services during the survey period. The results demonstrated that psychosocial quality of life was lower than that of the general Japanese adult population. Environmental factors, such as mother’s support and early diagnosis, were associated with better quality of life, and aggressive behaviors were associated with poorer quality of life, while expressive language level at preschool years, a conventional outcome predictor, did not predict quality of life. These results emphasize that quality of life measures should be included as outcome indicators in treating individuals with HFASD.
