Behavioral Therapy for Tourette Syndrome

This research is being done to determine whether a home-based behavioral therapy can be successfully used to treat tics in children with Tourette syndrome (TS). Behavioral therapy administered by a trained therapist has been shown to be helpful in reducing tics in children with Tourette syndrome. In this study, the investigators want to determine whether an instructional video can provide parents of children with TS with the tools necessary to successfully use behavioral therapy at home. The investigators also want to determine the effectiveness of home-based behavioral therapy as compared to improvement achieved when the therapy is provided by a trained therapist.
