Peer reviewed Peer reviewed

Williams, Zachary J.; Failla, Michelle D.; Gotham, Katherine O.; Woynaroski, Tiffany G.; Cascio, Carissa – Journal of Autism and Developmental Disorders, 2018
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…

DeMand, Alexandra; Johnson, Cynthia; Foldes, Emily – Journal of Autism and Developmental Disorders, 2015
The purpose of this study was to explore the psychometric properties of the Brief Autism Mealtime Behaviors Inventory (BAMBI). In a sample of 273 well-characterized children with ASD, we explored the factor structure of the BAMBI, determined the internal consistency of a newly derived factor structure and provide an empirically derived cut-off for…

A Comparison of Three Self-Report Measures of the Broader Autism Phenotype in a Non-Clinical Sample
Peer reviewed Peer reviewed

Ingersoll, Brooke; Hopwood, Christopher J.; Wainer, Allison; Donnellan, M. Brent – Journal of Autism and Developmental Disorders, 2011
Three self-report measures of the broader autism phenotype (BAP) were evaluated in terms of their internal consistency, distribution of scores, factor structure, and criterion-related validity in a non-clinical sample. All measures showed a continuous distribution. The SRS-A and BAPQ showed expected sex differences and were superior to the AQ in…

Further Evidence on the Factorial Structure of the Autism Spectrum Quotient (AQ) for Adults with and without a Clinical Diagnosis of Autism
Peer reviewed Peer reviewed

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…

Improved Diagnostic Validity of the ADOS Revised Algorithms: A Replication Study in an Independent Sample
Peer reviewed Peer reviewed
Direct linkDirect link
Oosterling, Iris; Roos, Sascha; de Bildt, Annelies; Rommelse, Nanda; de Jonge, Maretha; Visser, Janne; Lappenschaar, Martijn; Swinkels, Sophie; van der Gaag, Rutger Jan; Buitelaar, Jan – Journal of Autism and Developmental Disorders, 2010
Recently, Gotham et al. ("2007") proposed revised algorithms for the Autism Diagnostic Observation Schedule (ADOS) with improved diagnostic validity. The aim of the current study was to replicate predictive validity, factor structure, and correlations with age and verbal and nonverbal IQ of the ADOS revised algorithms for Modules 1 and 2…
