Psychometric Evaluation of the Short Sensory Profile in Youth with Autism Spectrum Disorder / Z. J. WILLIAMS in Journal of Autism and Developmental Disorders, 48-12 (December 2018)

Titre : Psychometric Evaluation of the Short Sensory Profile in Youth with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Z. J. WILLIAMS, Auteur ; M. D. FAILLA, Auteur ; K. O. GOTHAM, Auteur ; Tiffany G. WOYNAROSKI, Auteur ; Carissa J. CASCIO, Auteur Article en page(s) : p.4231-4249 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Factor analysis Psychometric Sensory Short Sensory Profile Validity Index. décimale : PER Périodiques Résumé : The Short Sensory Profile (SSP) is one of the most commonly used measures of sensory features in children with autism spectrum disorder (ASD), but psychometric studies in this population are limited. Using confirmatory factor analysis, we evaluated the structural validity of the SSP subscales in ASD children. Confirmatory factor models exhibited poor fit, and a follow-up exploratory factor analysis suggested a 9-factor structure that only replicated three of the seven original subscales. Secondary analyses suggest that while reliable, the SSP total score is substantially biased by individual differences on dimensions other than the general factor. Overall, our findings discourage the use of the SSP total score and most subscale scores in children with ASD. Implications for future research are discussed.

Titre : Classification of Children With Autism Spectrum Disorder by Sensory Subtype: A Case for Sensory-Based Phenotypes Type de document : Texte imprimé et/ou numérique Auteurs : Alison E. LANE, Auteur ; Cynthia A. MOLLOY, Auteur ; Somer L. BISHOP, Auteur Article en page(s) : p.322-333 Langues : Anglais (eng) Mots-clés : sensory autism phenotypes subtypes children classification model-based cluster analysis Short Sensory Profile Index. décimale : PER Périodiques Résumé : This study examines whether sensory differences can be used to classify meaningful subgroups of children with autism spectrum disorder (ASD). Caregivers of children with ASD aged 2–10 years (n?=?228) completed the Short Sensory Profile. Model-based cluster analysis was used to extract sensory subtypes. The relationship of these subtypes to age, gender, autism symptom severity, and nonverbal intelligence quotient (IQ) was further explored. Four distinct sensory subtypes were identified: (a) sensory adaptive; (b) taste smell sensitive; (c) postural inattentive; and (d) generalized sensory difference. The sensory subtypes differ from each other on two dimensions: (a) the severity of reported sensory differences; and (b) the focus of differences across auditory, taste, smell, vestibular and proprioceptive domains. Examination of the clinical features of each subtype reveals two possible mechanisms of sensory disturbance in autism: (a) sensory hyperreactivity; and (b) difficulties with multisensory processing. Further, the sensory subtypes are not well explained by other variables such as age, gender, IQ, and autism symptom severity. We conclude that classification of children using sensory differences offers a promising method by which to identify phenotypes in ASD. Sensory-based phenotypes may be useful in identifying behavioral features responsive to specific interventions thereby improving intervention effectiveness. Further validation of the sensory-based phenotypes by establishing neural and physiological correlates is recommended.
