<p>Tic disorders, such as Tourette’s syndrome, are chronic, childhood-onset neurological conditions that involve sudden, repetitive, and involuntary motor movements or vocalizations. Individuals with tics often experience premonitory urges, or aversive sensations that precede tics and are believed to be functionally related to their expression. Previous research has suggested that reinforcing tic suppression can effectively reduce tics, although the optimal contingencies that lead to such an effect have not been well-studied. The purpose of the current study was to compare a commonly used contingency, differential reinforcement of other behavior (DRO), to establish tic suppression with a contingency that included an option for participant-initiated breaks (DRO-break). Using an alternating treatments design, including four children with tics, results showed that three of four participants demonstrated tic reduction in both DRO conditions compared to baseline. Furthermore, DRO did not result in higher urge ratings compared to the baseline and DRO-break conditions for any of the participants. Finally, preference for the conditions was idiosyncratic, with two participants preferring DRO and two participants preferring DRO-break. Thus, DRO contingencies with and without breaks were equally effective at reducing tics compared to baseline and did not affect urges differently.</p>
