Project Description:
<p>The Tadpole study is an NIH-funded Autism Center of Excellence intervention network study carried out at three sites, University of Washington, University of California, Davis, and Vanderbilt University. This is a randomized, controlled long-term study of toddlers, aged 12-24 months to examine two important ways that autism treatments vary: intensity (15 versus 25 hours per week of intervention) and style (play-based versus discrete trial teaching). The project also examines potential moderators of intervention response: early vocal development, severity of ASD symptoms, and developmental impairment level at the beginning of intervention. This study grew out of more than a decade of developmental and intervention studies carried out by this collaborative group.</p>
