Efficiency of Early Intervention for Autism Spectrum Disorder

Intervention for autism spectrum disorder (ASD) in European French-speaking countries is often heterogeneous and poorly evaluated. Six French-speaking early intervention units for children with ASD following the Early Start Denver Model (ESDM) have been created since 2011 with the common aim to evaluate effectiveness and cost-efficiency of the ESDM applied to the European French-speaking public health system. In those units, Children receive ESDM at minimum 12H per week by trained therapist. Therapist work in collaboration with parents (at home) and preschool or nursery. The first aim of the investigators study is to evaluate the effectiveness of ESDM intervention 12 hours per week during 2 years on the global development of children with ASD compared to the interventions commonly available in the community.
