The French Version of the Revised Ritvo Autism and Asperger Diagnostic Scale: A Psychometric Validation and Diagnostic Accuracy Study.

The early recognition of ASD in adults is challenging, in particular due to the lack of appropriate and robust diagnostic tools. We performed a psychometric validation and diagnostic accuracy study of the French version of the RAADS-R on a sample of 305 adults: 105 with ASD without ID, 99 with psychiatric disorders, and 103 non-psychiatric control groups. The French version of the RAADS-R demonstrates good reliability and diagnostic validity, suggesting that it can help clinicians during the diagnostic process in adults with ASD without ID.
