Determining differences in social cognition between high-functioning autistic disorder and other pervasive developmental disorders using new advanced “mind-reading” tasks / Miho KURODA 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.554-561 Titre : Determining differences in social cognition between high-functioning autistic disorder and other pervasive developmental disorders using new advanced “mind-reading” tasks Type de document : Texte imprimé et/ou numérique Auteurs : Miho KURODA, Auteur ; Tokio UCHIYAMA, Auteur ; Akio WAKABAYASHI, Auteur ; Yuko YOSHIDA, Auteur ; Yoko KAMIO, Auteur ; Tomonori KOYAMA, Auteur Année de publication : 2011 Article en page(s) : p.554-561 Langues : Anglais (eng) Mots-clés : Mind-reading High-functioning-pervasive-developmental-disorders DSM-IV-TR Subgroup Modality Index. décimale : PER Périodiques Résumé : Deficits in understanding the mental state of others (“mind-reading”) have been well documented in individuals with pervasive developmental disorders (PDD). However, it is unclear whether this deficit in social cognition differs between the subgroups of PDD defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision. In this study, PDD was divided into high-functioning autistic disorder (HFA) (n = 17) and other PDD (n = 11) consisting of Asperger's disorder (n = 8) and PDD-NOS (n = 3), and differences in mind-reading ability was examined between the two clinical groups and controls (n = 50) using a new advanced naturalistic task consisting of short scenes from a TV drama showing communication in social situations. The task was divided into visual and auditory tasks to investigate which modality was more valuable for individuals with PDD to understand the mental state of others. The results suggest that social cognition differs significantly between individuals with HFA and those with other PDD, with no difference being found between those with other PDD and controls. Neither the auditory or visual modality was found to be dominant in subjects with PDD in the mind-reading task. Taken together, complex mind-reading tasks appear to be effective for distinguishing individuals with HFA from those with other PDD.

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.

Three groups of participants took part: n = 48 people with autism spectrum, n = 137 general population controls, and n = 1,250 university student controls. Each participant completed the Empathy Quotient (EQ) and the Systemizing Quotient (SQ). Results: The autism spectrum condition (ASC) group scored significantly lower than controls on the EQ, and significantly higher on the SQ. Among both control groups, females scored significantly higher than males on the EQ, whilst males scored significantly higher than females on the SQ. The distribution of ‘brain types’, based on the difference between EQ and SQ scores, showed distinct profiles for people with ASC, control males and control females.

Objective assessment of autism spectrum disorder based on performance in structured interpersonal acting-out tasks with prosodic stability and variability / Keiko OCHI in Autism Research, 17-2 (February 2024)  

Public ISBD [article]  inAutism Research > 17-2 (February 2024) . - p.395-409 Titre : Objective assessment of autism spectrum disorder based on performance in structured interpersonal acting-out tasks with prosodic stability and variability Type de document : Texte imprimé et/ou numérique Auteurs : Keiko OCHI, Auteur ; Masaki KOJIMA, Auteur ; Nobutaka ONO, Auteur ; Miho KURODA, Auteur ; Keiho OWADA, Auteur ; Shigeki SAGAYAMA, Auteur ; Hidenori YAMASUE, Auteur Article en page(s) : p.395-409 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract In this study, we sought to objectively and quantitatively characterize the prosodic features of autism spectrum disorder (ASD) via the characteristics of prosody in a newly developed structured speech experiment. Male adults with high-functioning ASD and age/intelligence-matched men with typical development (TD) were asked to read 29 brief scripts aloud in response to preceding auditory stimuli. To investigate whether (1) highly structured acting-out tasks can uncover the prosodic of difference between those with ASD and TD, and (2) the prosodic stableness and flexibleness can be used for objective automatic assessment of ASD, we compared prosodic features such as fundamental frequency, intensity, and mora duration. The results indicate that individuals with ASD exhibit stable pitch registers or volume levels in some affective vocal-expression scenarios, such as those involving anger or sadness, compared with TD and those with TD. However, unstable prosody was observed in some timing control or emphasis tasks in the participants with ASD. Automatic classification of the ASD and TD groups using a support vector machine (SVM) with speech features exhibited an accuracy of 90.4%. A machine learning-based assessment of the degree of ASD core symptoms using support vector regression (SVR) also had good performance. These results may inform the development of a new easy-to-use assessment tool for ASD core symptoms using recorded audio signals.

The Repetitive Behavior Scale-Revised (RBS-R) is a widely used questionnaire administered by parents or caregivers to assess RRBs in individuals with ASD. This study evaluated the psychometric properties of the RBS-R Japanese Version (RBS-R-J). The ASD and non-ASD groups comprised 274 and 36 participants, respectively. We examined corrected item-total correlation, Cronbach's alpha, and RBS-R-J scores of different diagnostic groups, as well as correlations between RBS-R-J scores and intelligence quotient (IQ), autistic symptoms, adaptive/maladaptive functioning, aberrant behaviors, and sensory processing. All items showed moderate corrected item-total correlations. Cronbach's alpha coefficient was .93. We found significant differences in the mean RBS-R-J scores of the low-functioning ASD group and the intellectual disabilities group, and of low-functioning and high-functioning ASD groups. RBS-R-J scores negatively correlated with IQ and scores on the Sensory Profile (Japanese version) and Adaptive Behavior Composite of the Maladaptive Behavior Index of the Vineland Adaptive Behavior Scales-Second Edition (VABS-II; Japanese version), but positively correlated with scores on the peak and current symptoms subscales of the Pervasive Developmental Disorders Autism Society Japan Rating Scale, the VABS-II, and the Aberrant Behavior Checklist-Community (Japanese version). From these results, we conclude that RBS-R-J showed good reliability, diagnostic validity, and convergent validity, indicating that it is a reliable, valid instrument for use among ASD individuals in clinical and research settings.
