Del Giudice, Teresa; Dose, Christina; Görtz-Dorten, Anja; Steiner, Jennifer; Bruning, Nicole; Bell, Hannah; Roland, Pamela; Walter, Daniel; Junghänel, Michaela; Döpfner, Manfred – Journal of Autism and Developmental Disorders, 2021
To examine the factor structure of autism spectrum disorder (ASD) and the psychometric properties of the German Symptom Checklist for Autism Spectrum Disorders (SCL-ASD). Data were collected from 312 clinical referrals with suspected ASD (2-18 years). Confirmatory factor analyses and analyses of reliability, convergent and divergent validity were…

Sansone, Stephanie M.; Widaman, Keith F.; Hall, Scott S.; Reiss, Allan L.; Lightbody, Amy; Kaufmann, Walter E.; Berry-Kravis, Elizabeth; Lachiewicz, Ave; Brown, Elaine C.; Hessl, David – Journal of Autism and Developmental Disorders, 2012
Animal studies elucidating the neurobiology of fragile X syndrome (FXS) have led to multiple controlled trials in humans, with the Aberrant Behavior Checklist-Community (ABC-C) commonly adopted as a primary outcome measure. A multi-site collaboration examined the psychometric properties of the ABC-C in 630 individuals (ages 3-25) with FXS using…

Brinkley, Jason; Nations, Laura; Abramson, Ruth K.; Hall, Alicia; Wright, Harry H.; Gabriels, Robin; Gilbert, John R.; Pericak-Vance, Margaret A. O.; Cuccaro, Michael L. – Journal of Autism and Developmental Disorders, 2007
Exploratory factor analysis (varimax and promax rotations) of the aberrant behavior checklist-community version (ABC) in 275 individuals with Autism spectrum disorder (ASD) identified four- and five-factor solutions which accounted for greater than 70% of the variance. Confirmatory factor analysis (Lisrel 8.7) revealed indices of moderate fit for…
