Identifying effective, community-based specialized interventions for young children with autism spectrum disorder is an international clinical and research priority. We evaluated the effectiveness of the Early Start Denver Model intervention in a group of young children with autism spectrum disorder living in an Italian community compared to a group of Italian children who received treatment as usual. A total of 22 young children diagnosed with autism spectrum disorder received the Early Start Denver Model in a center-based context for 6 h per week over 6 months. The Early Start Denver Model group was compared to a group of 70 young children diagnosed with autism spectrum disorder who received treatment as usual for an average of 5.2 h over 6 months. Children in both groups improved in cognitive, adaptive, and social skills after 3 months and 6 months of treatment. Children in the Early Start Denver Model group made larger gains in cognitive and social skills after 3 and 6 months of treatment. The Early Start Denver Model group made larger gains in adaptive skills after 3 months of treatment. Our results are discussed in terms of implications for intervention research and clinical practice. Our study supports the positive impact of the Early Start Denver Model in a non-English-speaking community.

Little is known about use of early interventions for autism spectrum disorder in Europe. Parents of children with autism spectrum disorder aged 7 years or younger (N = 1680) were recruited through parent organisations in 18 European countries and completed an online survey about the interventions their child received. There was considerable variation in use of interventions, and in some countries more than 20% of children received no intervention at all. The most frequently reported interventions were speech and language therapy (64%) and behavioural, developmental and relationship-based interventions (55%). In some parts of Europe, use of behavioural, developmental and relationship-based interventions was associated with higher parental educational level and time passed since diagnosis, rather than with child characteristics. These findings highlight the need to monitor use of intervention for children with autism spectrum disorder in Europe in order to contrast inequalities.
