Habit reversal training for tic disorders in children and adolescents.

Chronic tic disorders, including Tourette's syndrome (TS), affect approximately .5% of children and adolescents. Although strong evidence exists supporting a neurobiological etiology, operant factors may play a role in the maintenance of tic behaviors. Pharmacological approaches remain the most commonly used intervention for chronic tic disorder in children and adults. Nevertheless, the unpredictable efficacy and serious side effects associated with medication along with parental concerns about long-term medication use in children underlie the need for nonpharmacological interventions for tics in this age group. This article reviews the rationale and evidence base for the use of habit reversal training (HRT), a multicomponent behavioral treatment package, as a treatment for childhood tics. Each of the primary treatment components of HRT is described and implementation is illustrated in case report format. A growing body of data suggests that HRT is a well-tolerated and efficacious intervention for tic disorders in this age group.
