We are happy to announce the release of a new scientific study in the European Journal of Behaviour providing evidence-based work on the Analysis of Community Implementation of Early Behavioral Intervention. This work provides ongoing evidence that higher intensity behavioural intervention yields better outcomes. The study was carried out by our esteemed colleagues and research partners at Oslo Metropolitan University, Department of Behavioural Science, led by Sigmund Eldevik and Kristine Titlestad.

The study evaluated the outcome of Early Intensive Behavioural Intervention for children with Autism Spectrum Disorders (ASD) as it was provided through public service providers in Norway. The first group of 21 children received low-intensity intervention (11.1 weekly hours), a second group of 26 children higher intensity intervention (18.1 weekly hours), and a third group of 17 children received eclectic special education. Group assignment was based on independent referrals. They compared outcomes on adaptive behaviour, ASD severity, and intellectual functioning after one year. The lower and higher intensity behavioural intervention groups received fewer hours than what is recommended but did significantly better than the eclectic group. Moreover, the higher intensity behavioural group did better than the lower intensity behavioural group. Nevertheless, gains in both groups were modest in comparison to what is reported for more intensive intervention.
