Validation of the Autism Diagnostic Interview: 3rd Edition
The goal of this study is to support the validation of a revision to the Autism Diagnostic Interview – Revised (ADI-R). The ADI-R is a highly validated diagnostic tool used in clinical assessments for autism spectrum disorder and widely used in research for participant characterization and inclusion. Aims: 1. To explore the validity of the ADI-3 (concurrent validity with ADI-R and other autism instruments; predictive validity with best estimate clinical diagnosis). 2. To explore the reliability of the ADI-3 (interrater, test-retest, internal consistency) 3. To derive diagnostic algorithms that better match DSM-5 criteria and maximize sensitivity and specificity 4. To ensure that changes (e.g., reduced length, new format to codes) yield sufficient information to inform diagnoses.
