Habit reversal training
Habit reversal training (HRT) is a "multicomponent behavioral treatment package originally developed to address a wide variety of repetitive behavior disorders".
HRT consists of five components:
- awareness training,
- competing response training,
- contingency management,
- relaxation training, and
- generalization training.
Research on the efficacy of HRT for the aforementioned behavioral disorders have produced consistent, large effect sizes (approximately 0.80 across the disorders). It has met the standard of a well-established treatment for stuttering, thumb sucking, nail biting, and TMJ.
For tic disorders
In the case of tics, these components are intended to increase tic awareness, develop a competing response to the tic, and build treatment motivation and compliance. HRT is based on the presence of a premonitory urge, or sensation occurring before a tic. HRT involves replacing a tic with a competing response—a more comfortable or acceptable movement or sound—when a patient feels a premonitory urge building.
Controlled trials have demonstrated that HRT is an acceptable, tolerable, effective and durable treatment for tics; HRT reduces the severity of vocal tics, and results in enduring improvement of tics when compared with supportive therapy. HRT has been shown to be more effective than supportive therapy and in some studies medication. HRT is not yet proven or widely accepted, but large-scale trials are ongoing and should provide better information about its efficacy in treating TS. Studies through 2006 are "characterized by a number of design limitations, including relatively small sample sizes, limited characterization of study participants, limited data on children and adolescents, lack of attention to the assessment of treatment integrity and adherence, and limited attention to the identification of potential clinical and neurocognitive mechanisms and predictors of treatment response". Additional controlled studies of HRT are needed to address whether HRT, medication, or a combination of both is most effective, but in the interim, "HRT either alone or in combination with medication should be considered as a viable treatment" for tic disorders.
