Is the Autism-Spectrum Quotient a Valid Measure of Traits Associated with the Autism Spectrum? A Rasch Validation in Adults with and Without Autism Spectrum Disorders / Lars-Olov LUNDQVIST in Journal of Autism and Developmental Disorders, 47-7 (July 2017)
[article]
Titre : Is the Autism-Spectrum Quotient a Valid Measure of Traits Associated with the Autism Spectrum? A Rasch Validation in Adults with and Without Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Lars-Olov LUNDQVIST, Auteur ; Helen LINDNER, Auteur Article en page(s) : p.2080-2091 Langues : Anglais (eng) Mots-clés : Autistic traits Adults Autism-Spectrum Quotient Rasch model Index. décimale : PER Périodiques Résumé : The Autism-Spectrum Quotient (AQ) is among the most widely used scales assessing autistic traits in the general population. However, some aspects of the AQ are questionable. To test its scale properties, the AQ was translated into Swedish, and data were collected from 349 adults, 130 with autism spectrum disorder (ASD) and 219 without ASD, and analysed with Rasch. Several scale properties of the AQ were satisfactory but it did not meet the criterion of a unidimensional measure of autistic traits. The Rasch analysis showed that the 50-item AQ could be reduced to a 12-item subset with little loss of explanatory power, with the potential to efficiently measure the degree to which adults with and without ASD show autistic traits.

Titre : Brief Report: Psychometric Properties of the Ability in Behavior Assessment and Interventions for Teachers-Revised (ABAIT-R) Type de document : Texte imprimé et/ou numérique Auteurs : Rahul NAIR, Auteur ; Anuradha DUTT, Auteur ; Tine NIELSEN, Auteur Article en page(s) : p.1081-1087 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Functional behavior assessments and interventions Rasch model Scale validation Teacher training Index. décimale : PER Périodiques Résumé : Given the importance of competencies in functional behavior assessment (FBA) and behavioral interventions among teachers for managing problem behaviors among children with autism spectrum disorder (ASD) and other developmental disabilities, a previously reported ability in behavior assessment and interventions for teachers (ABAIT) needed improvements in the multiple-choices by adding a 'don't know' option. This study reports on the psychometric properties of this revised scale (ABAIT-R) among 102 special educators assessed using Rasch models. It was found that the model had good fit and a wide spread of difficulties (3.63 to - 2.60). ABAIT-R had good targeting (over 85%) and high reliability (0.79). The assumptions of the model were met recommending sufficiency for the use of summated score from ABAIT-R among teachers.
