The purpose of this research study is to compare two different online group treatments for tics:

1) a mindfulness-based program (Mindfulness-based Intervention for Tics or MBIT, for short), and

2) a psychoeducational and supportive therapy program (Tic Information and Coping Strategies or TICS, for short).

We hope to determine which treatment is more helpful for adults with a tic disorder.

Please note: We are no longer enrolling participants.
