About this study
Aversive sensory phenomena such as premonitory urges play a central role in the behavioral treatment model of tics. Extinction learning and extinction recall are learning processes implicated within this model, but are still understudied for individuals with Tourette syndrome (TS). This study examines extinction learning and extinction recall in adults with TS using an experimental task. This study will also explore the relationship between extinction processes (i.e., extinction learning and extinction recall) and treatment outcomes with behavior therapy. Findings from this investigation will be used to update the behavioral treatment model, which serves as the basis for evidence-based behavioral interventions.

What is being measured
The primary outcome is the main question the study is designed to answer.
Tic severity as assessed by the Hopkins Motor and Vocal Tic Scale (HM/VTS)
Patient will nominate up to five motor and five vocal tics they deem bothersome on the HM/VTS. Each bothersome tic is then rated by a clinician on the composite two (vocal and motor) 5-point HM/VTS scale ranging from none (0) to severe (4) for the motor as well as vocal tics. The individual tic scores are summed (minimum of 0 and maximum of 40) and averaged together to create an average tic severity score.
Measured: Within 1 week after completion of HRT
Secondary outcomes (1)
Tic severity as assessed by the Yale Global Tic Severity Scale-Revised (YGTSS)
The YGTSS is a clinician-rated semi-structured interview that measures tic symptom severity over the previous week. It consists of 10-items that assess different dimensions of tic severity for motor and vocal tics, which are rated on a 0-5 scale. The YGTSS produces a Total Tic Score (range: 0-50), with higher ratings indicating greater tic severity. The YGTSS has demonstrated treatment sensitivity to pharmacotherapy and behavioral interventions.
Measured: Within 1 week after completion of HRT

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tic severity as assessed by the Hopkins Motor and Vocal Tic Scale (HM/VTS) (time frame: Within 1 week after completion of HRT). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Oct 2023.
