Study Finds Comprehensive Home-Based Program Improves IQ, Language, Social Ability

WebMD Health NewsReviewed by Louise Chang, MDNov. 30, 2009 -- A new, home-based program for toddlers with autism spectrum disorder (ASD) that combines behavioral change techniques in a playful environment boosted the children's IQ, language ability, and social interaction skills more than a community-based program, according to a new study.
The home-based program included up to 20 hours a week of therapist intervention, plus the intervention of parents, who were taught the same skills.
''This intervention is designed to be appropriate for children as young as 12 months of age," says study researcher Geraldine Dawson, PhD, chief science officer of Autism Speaks, a science and advocacy organization. She conducted the research while a professor of psychology and director of the University of Washington's Autism Center, Seattle.
''We found that after two years the children who received the intervention had made significant gains in their IQ, their language ability, their adaptive behavior, and their social interaction," Dawson tells WebMD.
The IQ of children in the new home-based program -- called the Early Start Denver Model -- rose on average about 18 points after two years, she says. The IQ of the children in the community-based comparison group increased seven points.
''When you see an IQ gain that is this large, the child is much more likely to be able to enter a regular classroom and develop friendships," Dawson says.
The study is published online in the journal Pediatrics.
