Internet-based Behavior Therapy for Adults With Tourette Syndrome

The central component of the intervention will be ERP. During the treatment, participants will receive information about tics and how to work with ERP. Continuously throughout the treatment patients will work with exposing themselves to situations that trigger their premonitory urges and practice suppressing their tics. They will learn different strategies to provoke their premonitory urges to make suppression of their tics more challenging and gradually increase the time they can suppress the tics. A central tool in the treatment will be the Ticstimer, a worksheet where patients will continuously record their ERP practice, and the time they manage to suppress tics. The patients will be encouraged to work with the Ticstimer daily.

Participants who are randomized to the control group will receive access to brief psychoeducational content in the platform in combination with general psychological support from a therapist. No active BT components (BT, Habit Reversal Training, applied relaxation) are provided to the participants in the control group. The therapists will welcome the patients to the treatment, encourage them to engage in the treatment content and reach out to the therapist if they have any questions. Thereafter, the therapists will only reply to the patients' messages without taking any contact initiative themselves (unless there is an indication of severe deterioration or severe depressive symptoms or suicidal ideation requiring medical attention)
