ASD prevalence study across Europe: developing a school-based screening approach in the ASDEU project

Objectives: The main objective of the present work is to describe the strategy of the Autism Spectrum Disorder in the European Union (ASDEU) project to estimate the prevalence of ASD in school-aged children (7-9 years) across Europe. The focus of the presentation is on the novel field study strategy and aims to be a reflection on what we have learned regarding standardization of study methods across sites, what has worked well and what could be done differently in the future.
