PURPOSE: The purpose of this article is to review the recent literature investigating the efficacy of HRT for treating children with chronic tic disorders. SOURCES: This review examines single-subject design studies and randomized, controlled trials of HRT conducted in children with chronic tic disorders since 2000. CONCLUSIONS: Intervention built on HRT appears to be effective for decreasing tic severity in children and adolescents. Results from a recent multisite trial suggest that incorporation of functional analysis may enhance the effectiveness of traditional HRT.
