Infant quantitative risk for autism spectrum disorder predicts executive function in early childhood / R. L. STEPHENS in Autism Research, 11-11 (November 2018)
[article]
Titre : Infant quantitative risk for autism spectrum disorder predicts executive function in early childhood Type de document : Texte imprimé et/ou numérique Auteurs : R. L. STEPHENS, Auteur ; Linda R. WATSON, Auteur ; Elizabeth R. CRAIS, Auteur ; J. S. REZNICK, Auteur Article en page(s) : p.1532-1541 Langues : Anglais (eng) Mots-clés : autism spectrum disorder early childhood executive function infant quantitative measure sensory Index. décimale : PER Périodiques Résumé : Much of the current research concerning autism spectrum disorder (ASD) focuses on early identification of behaviors that may indicate future deficits or higher risk for a later diagnosis. Additionally, there exists a strong claim regarding the dimensional nature of ASD, such that even among non-diagnosed individuals, a continuous distribution of symptom severity can be observed. Executive function (EF) has been widely studied in children, adolescents, and adults with ASD, with a robust body of research supporting widespread EF deficits in diagnosed individuals. However, it remains unclear how the degree of ASD symptomatology, outside of the presence of a diagnosis, affects EF abilities in a community sample. The First Year Inventory 2.0 (FYI 2.0), a parent-report measure, was designed to identify infants at 12 months who are at risk for an eventual ASD diagnosis. In the current study, a continuous scoring scale was used to examine risk (overall, Social-Communication, and Sensory-Regulatory) from a dimensional perspective. Parents also completed the Behavior Rating Inventory of Executive Function-Preschool Version and the Social Responsiveness Scale-2nd edition when their children were 42 months (3.5 years) old. Each FYI 2.0 risk variable significantly predicted scores on an overall EF composite and specific EF subscales. When controlling for general ASD symptomatology, Sensory-Regulatory risk still significantly predicted EF deficits. This research provides additional support for a quantitative consideration of risk for ASD and presents novel findings regarding the relation between infant behaviors indicative of ASD risk and EF in early childhood. Autism Research 2018, 11: 1532-1541. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Children with autism spectrum disorder (ASD) often have difficulty with executive function (EF) tasks that require a set of mental processes involved in goal-directed behaviors. Studying children without ASD who may have symptoms affecting EF is also important. This study demonstrates that certain infant behaviors related to ASD are linked to early childhood EF difficulties. These results support looking at a range of ASD symptoms to better understand children who struggle with EF and potentially design tools to help them.

Titre : Assessment of Autistic Traits in Children Aged 2 to 4½ Years With the Preschool Version of the Social Responsiveness Scale (SRS-P): Findings from Japan Type de document : Texte imprimé et/ou numérique Auteurs : Andrew STICKLEY, Auteur ; Yoshiyuki TACHIBANA, Auteur ; Keiji HASHIMOTO, Auteur ; Hideyuki HARAGUCHI, Auteur ; Atsuko MIYAKE, Auteur ; Seiichi MOROKUMA, Auteur ; Hiroshi NITTA, Auteur ; Masako ODA, Auteur ; Yukihiro OHYA, Auteur ; Ayako SENJU, Auteur ; Hidetoshi TAKAHASHI, Auteur ; Takanori YAMAGATA, Auteur ; Yoko KAMIO, Auteur Article en page(s) : p.852-865 Langues : Anglais (eng) Mots-clés : ASD autistic traits quantitative measure reliability validity preschool children questionnaire Index. décimale : PER Périodiques Résumé : The recent development and use of autism measures for the general population has led to a growing body of evidence which suggests that autistic traits are distributed along a continuum. However, as most existing autism measures were designed for use in children older than age 4, to date, little is known about the autistic continuum in children younger than age 4. As autistic symptoms are evident in the first few years, to address this research gap, the current study tested the preschool version of the Social Responsiveness Scale (SRS-P) in children aged 2 to 4½ years in clinical (N?=?74, average age 40 months, 26–51 months) and community settings (N?=?357, average age 39 months, 25–50 months) in Japan. Using information obtained from different raters (mothers, other caregivers, and teachers) it was found that the scale demonstrated a good degree of internal consistency, inter-rater reliability and test-retest reliability, and a satisfactory degree of convergent validity for the clinical sample when compared with scores from diagnostic “gold standard” autism measures. Receiver operating characteristic analyses and the group comparisons also showed that the SRS-P total score discriminated well between children with autism spectrum disorder (ASD) and those without ASD. Importantly, this scale could identify autistic symptoms or traits distributed continually across the child population at this age irrespective of the presence of an ASD diagnosis. These findings suggest that the SRS-P might be a sensitive instrument for case identification including subthreshold ASD, as well as a potentially useful research tool for exploring ASD endophenotypes.
