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. Results from this latter 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.
The creation of ADT and its 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); 10th annual world congress of neurotalk 2019, Osaka, Japan (20198); 18th congres of the european society of child and adolescent psychiatry, Vienna, Austria (2019); 12th international congres of Autism Europe, Nice, France (2019); 19th international meeting of speech therapy -special ASD, Paris (2019).
