The document summarizes two studies on interventions for children with autism. The Thailand study involved 32 children who received either typical treatment or DIRFloortime supplemented treatment for 3 months. Parents in the intervention group added 15 hours per week of DIRFloortime. Children in this group showed greater improvements on assessment scales compared to typical treatment. The Canada study was a randomized controlled trial of 51 children who received either DIRFloortime therapy and coaching or community treatment. Children in the DIRFloortime group showed significantly greater improvements in social interaction capacities like attention, involvement, and joint attention.
