Validation of the French Adaptation of the RAADS-R Scale : Scale of Asperger Syndrome Diagnosis (RAADS-R)

July 5, 2016 updated by: University Hospital, Montpellier

Validation of the French Adaptation of the Scale Aiding in the Diagnosis of the Autism Spectrum Disorders : Scale of Asperger Syndrome Diagnosis

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. The objective of this study is to perform a complete validation of this scale in the french version. 300 adults should be included, including 100 adults with high-functioning autism, 100 adults with another psychiatric disorder, and 100 adults without developmental disabilities and / or mental.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
324

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
