The ADT results from several years of research within the context of a Ph.D programme at the Université Libre de Bruxelles. It was created in response to the lack of effective ASD screening in many European countries. Its validation started with an exploratory study, followed by a prospective multicentric study. This latter included a sample of 126 children waiting for a diagnostic assessment in 3 Belgian and French official specialist ASD clinics. Its development followed rigorous scientific guidelines, via blind ratings, inclusion of a controle group, clinical cohorts’ follow-up and use of gold standard tools during final diagnostic assessment. Results indicated a value of 0.94 for specificity and 0.83 in terms of sensibility, allowing for differential screening between risk of ASD and probability of another (neuro)developmental pathology.
Creation of ADT and final results were presented in various international congresses such as the 10th international Congress of Autism Europe, Budapest, Hungary (2013); 9th international congress of child and adolescent psychopathology, London, UK (2014); 15th international conference of child and adult psychiatry association, Athens, Greece (2015); 17th international conference of the european society of child and adolescent psychiatry, Geneva, Switzerland (2017); French congress of child and adolescent psychiatry and allied disciplines, Angers, France (2018). To come in 2019: 10th annual world congress of neurotalk 2019, Osaka, Japan (May); 19th international meeting of speech therapy -special ASD, Paris (Decembre).
