Abstract:

The purpose of this pilot study is to investigate reliability and validity of Modified Turkish Version of Autism Behavior Checklist (ABC) before carrying out Turkish standardization study. Participants included 163 principal caregivers/parents and 164 educators/professionals of individuals with Autism Spectrum Disorder (ASD) ages between 3 and 20. In order to explore discriminant validity of Modified Turkish Version of Autism Behavior Checklist, data were also collected from individuals with intellectual disability, hearing disability, and from those with typical development. Modified Turkish Version of Autism Behavior Checklist and Gilliam Autism rating Scale-2-Turkish Version were used to collect data. Results revealed that Modified Turkish Version of Autism Behavior Checklist has acceptable level of discriminant validity and criterion-related validity. Reliability results also indicated that Modified Turkish Version of Autism Behavior Checklist has acceptable level of internal reliability, and test-retest reliability. Other analyses also supported its reliability. Suggestions were provided for Turkish standardization of Modified Turkish Version of Autism Behavior Checklist.
