Overview
Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder recognized as a major national cause in 2012. The French Autism Plan 2018-2022 emphasizes early diagnosis and intervention for better cognitive and behavioral outcomes. The COVID-19 pandemic complicates the use of the ADOS-2 diagnostic tool due to mask-wearing and distancing requirements. To address this, the Brief Observation Symptoms of Autism (BOSA) has been adapted for remote assessment. The BOSA, translated into French, is recommended alongside the Autism Diagnostic Interview -Revised (ADI-R) for complementary diagnostic algorithms. No similar projects have been undertaken in France or Canada.
Description
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by difficulties in social interaction, communication, and restricted, repetitive behaviors. Early diagnosis is critical for intervention and improving developmental outcomes. The French 2018-2022 Autism Plan emphasizes timely diagnosis to optimize care and reduce long-term impacts. Current tools, including the Autism Diagnostic Observation Schedule (ADOS-2) and the Autism Diagnostic Interview-Revised (ADI-R), are widely used but require in-person assessment. The COVID-19 pandemic has complicated the use of such tools due to mask-wearing and social distancing, limiting effective evaluation.
To address this, the Brief Observation of Symptoms of Autism (BOSA) has been adapted for remote use, offering a new approach to diagnosing ASD in children. This study will implement a teleconsultation model, utilizing BOSA and a shortened version of ADI-R, for children aged 24 months to 5 years with suspected ASD. The BOSA was adapted and translated into French under the approval of its creators and WPS publishing. The study aims to determine whether teleconsultation-based evaluations can achieve similar diagnostic accuracy as in-person assessments.
It is hypothesized that remote diagnosis using BOSA and ADI-R will have an accuracy rate of at least 80% compared to in-person ADOS-2 assessments, across key diagnostic domains such as social interaction, communication, and restrictive behaviors. The teleconsultation process may provide a more accessible, less disruptive diagnostic pathway, especially in situations where in-person evaluations are delayed or impractical.
This study will be one of the first in France and Canada to implement such a remote diagnostic model, addressing a gap in the literature and offering a potential solution to diagnostic delays caused by the pandemic. Concordance between teleconsultation and in-person diagnostic outcomes will be measured to assess the reliability and feasibility of this approach.
