Existing behavioral interventions for CTDs have comparable efficacy to pharmacological treatments but still leave many individuals with significant tic symptoms and impairment. One approach to improving existing treatments involves conducting pre-clinical laboratory research to evaluate procedures that may be attractive candidates for applied treatment research. Reinforcing tic suppression via differential reinforcement of other behavior (DRO) procedures produces decreases in tic frequency of ~80% in youth with CTDs; however, a more robust reduction may be needed to affect durable clinical change. The present study compared the …
