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.

Sensory Processing Patterns and Fusiform Activity During Face Processing in Autism Spectrum Disorder / Ayaka KUNO-FUJITA in Autism Research, 13-5 (May 2020)  

Public ISBD [article]  inAutism Research > 13-5 (May 2020) . - p.741-750 Titre : Sensory Processing Patterns and Fusiform Activity During Face Processing in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Ayaka KUNO-FUJITA, Auteur ; Toshiki IWABUCHI, Auteur ; Keisuke WAKUSAWA, Auteur ; Hiroyuki ITO, Auteur ; Katsuaki SUZUKI, Auteur ; Akira SHIGETOMI, Auteur ; Kosaka HIROTAKA, Auteur ; Masatsugu TSUJII, Auteur ; Kenji J. TSUCHIYA, Auteur Article en page(s) : p.741-750 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  fMRI  face processing  fusiform gyrus  sensory processing  sensory profile Index. décimale : PER Périodiques Résumé : A growing body of evidence has indicated that individuals with autism spectrum disorder (ASD) exhibit abnormal reactions to sensory stimuli and impaired face processing. Although behavioral studies have reported that individual differences in sensory processing patterns are correlated with performance in face processing tasks, the neural substrates underlying the association between sensory processing patterns and face processing remain unknown. Using functional magnetic resonance imaging, the present study examined the relationships between sensory processing patterns assessed with the Adolescent/Adult Sensory Profile (AASP) and brain activity during a one-back task with two types of stimuli (face or house pictures). We enrolled 18 Japanese adults with ASD and 19 age- and IQ-matched controls. Sensation Avoiding scores, which were assessed using the AASP, were positively correlated with right fusiform activity during the presentation of pictures of faces in the ASD group, but not in the control group. This suggests that abnormal sensory processing patterns in ASD are associated with abnormal face-related brain activity, possibly resulting in impaired face processing. Autism Res 2020, 13: 741-750. (c) 2020 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Sensory abnormalities are one of the most common symptoms in people with autism spectrum disorder (ASD). This study shows that individuals with ASD who react abnormally to sensory stimuli also exhibit atypical brain activity when recognizing faces. Abnormal sensory processing may partly explain the difficulty that people diagnosed with ASD have in identifying others' faces.

Validation of an interview-based rating scale developed in Japan for pervasive developmental disorders / Hiroyuki ITO in Research in Autism Spectrum Disorders, 6-4 (October-December 2012)

We examined the reliability and validity of PARS on the basis of data from 572 participants (277 PDD patients and 295 nonclinical controls). Inter-rater reliability was sufficient at both the item and scale level. Factor analysis extracted four subscales, for which internal consistency was found to be high. The sub and total scores of PARS showed correlations with the domain and total scores of ADI-R, in line with theoretical prediction, indicating the convergent validity of PARS. A receiver operating characteristic analysis showed that PARS has good discriminative validity in differentiating between PDD patients and nonclinical controls, regardless of intellectual capacity. Considering that PARS can be easily implemented by professionals with appropriate knowledge regarding PDDs, PARS may be superior to the existing instruments in terms of cost performance.
