Research Project: The Effectiveness of Community-Based Intensive Behavioural Intervention: A Waitlist Comparison Study

The purpose of this study is to extend previous research about the effectiveness of Intensive Behavioural Intervention (IBI) in a community setting. The study aims to compare changes over time for children receiving IBI to changes over time for an individually matched waitlist comparison group.
