Our purpose in this study was to further examine the psychometric properties of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We first investigated the factor structure and the internal consistency of the scale. The bifactor model showed good fit and strong reliability. Second, we used multiple-indicators…

Although self-reported measures are frequently used to assess adults with autism spectrum disorders (ASD), the validity of self-reports is under-researched in ASD. The core symptoms of ASD may negatively affect the psychometric properties of self-reported measures. The aim of the present study was to test the validity and reliability of…

Lau, Winnie Yu Pow; Kelly, Adrian B.; Peterson, Candida Clifford – Journal of Autism and Developmental Disorders, 2013
The Autism Spectrum Quotient (AQ) has been widely used for measuring autistic traits however its factor structure has been primarily determined from nonclinic populations. This study aimed to establish an internally coherent and reliable factor structure for the AQ using a sample of 455 Australian adults of whom 141 had autism spectrum disorder…

Hoekstra, Rosa A.; Bartels, Meike; Cath, Danielle C.; Boomsma, Dorret I. – Journal of Autism and Developmental Disorders, 2008
The factor structure of the Dutch translation of the Autism-Spectrum Quotient (AQ; a continuous, quantitative measure of autistic traits) was evaluated with confirmatory factor analyses in a large general population and student sample. The criterion validity of the AQ was examined in three matched patient groups (autism spectrum conditions (ASC),…

Campbell, Jonathan M. – Journal of Autism and Developmental Disorders, 2008
The Shared Activities Questionnaire (SAQ) is a self-report measure of children's behavioral intentions towards peers with disabilities. The SAQ has been validated as a measure of elementary school students' attitudes towards peers with disabilities. In the present study, psychometric properties of the SAQ as a measure of middle school students'…
