Brief summary: The diagnosis of developmental disorders in adults is still difficult. Indeed, in France, there is not questionnaires to easily and accurately diagnose this disorder. Several diagnostic scales were developed in English. Among them, RAADS-R scale, which is a clinical tool that aims to better identify autism spectrum disorders including mild forms in adult people and help to diagnose of high-functioning autism . The objective of this study is to perform a complete validation of this scale in the french version.

Detailed description: The diagnosis of developmental disorders in adults is still difficult. Indeed, in France, there is not questionnaires to easily and accurately diagnose this disorder. Several diagnostic scales were developed in English. Among them, RAADS-R scale, which is a clinical tool that aims to better identify autism spectrum disorders including mild forms in adult people and help to diagnose of high-functioning autism . This scale is a self-administered questionnaire completed by the person himself assisted by a clinician (psychiatrist, psychologist) which ensures the understanding of issues and the choice of answers. The scale contains 80 items including 64 questions describe specific symptoms of autism spectrum disorders and 16 questions describe non-symptomatic behaviors.
