Key Points Question Is therapist-supported, internet-delivered exposure and response prevention (ERP) efficacious and cost-effective for young people with Tourette syndrome or chronic tic disorder? Findings In this randomized clinical trial of 221 youths with Tourette syndrome or chronic tic disorder who received either therapist-supported internet-delivered ERP or structured education, both groups significantly improved over time, with no between-group differences in tic severity. However, ERP was associated with significantly higher treatment response rates (47% vs 29%) at little additional cost. Meaning Both internet-delivered ERP and structured education were associated with improvements in tic severity, but ERP led to higher treatment response rates.
