- Brief Summary
This research study is being done to compare a mindfulness-based intervention for tics (MBIT) to psychoeducation with relaxation and supportive therapy (PRST) for individuals with Tourette's syndrome or Persistent Tic Disorders (collectively TS). It is the investigator's hope that this information cam be used to improve current treatments for individuals with TS.
- Detailed Description
Tourette's syndrome and other persistent tic disorders (collectively, TS) is a condition that onsets in childhood and affects \~1% of the population. Alongside motor and vocal tics, patients with TS experience distressing somatosensory sensations (i.e., premonitory urges) and co-occurring mental health conditions such as anxiety disorders, depressive disorders, obsessive-compulsive disorder (OCD), and ADHD. Tics and comorbid symptoms cause individuals with TS significant distress and impairment across life domains (e.g., physical, social, academic, occupational, emotional, and familial). Two evidence-based treatments exist for TS: behavior therapy and pharmacotherapy. Behavior therapy \[often referred to as habit reversal training (HRT) or the comprehensive behavioral intervention for tics (CBIT)\] is an evidence-based treatment that has been shown to reduce the severity of tic symptoms, and has a low risk for adverse effects. Although behavior therapy is recognized as a first-line intervention for TS, less than 40% of adults with TS respond to this evidence-based treatment. Additionally, current behavioral interventions are often inaccessible for adults with TS. While pharmacotherapy for tic management (e.g., antipsychotic medications) has been shown to be effective, these treatments can have adverse side effects with detrimental health consequences. Thus, there is a critical need for new treatments for adults with TS that are efficacious for reducing tic severity, beneficial for co-occurring conditions, and have few adverse health effects. Mindfulness-based interventions have proven beneficial for adults with a wide range of neuropsychiatric conditions. Based on the investigator's prior work, the investigators believe that a mindfulness-based intervention for tics (MBIT) is beneficial for adults with TS.
This project is a randomized controlled trial (RCT) that will compare the efficacy of a mindfulness-based intervention for tics (MBIT) to psychoeducation with relaxation and supportive therapy (PRST) in 150 adults with TS. All interventions and assessments will be delivered remotely using secure telehealth services platforms and online electronic data capture systems. An independent evaluator (IE) masked to treatment condition will administer all assessments during the treatment and follow-up periods. The investigators will test the mechanisms by which MBIT reduces tic severity, and examine the efficacy of MBIT relative to PRST for common co-occurring psychiatric symptoms and quality of life impairments-towards "treating the whole person". Finally, the investigators will explore the sustained therapeutic improvement from MBIT over a 6-month follow-up period focusing on tic severity, tic-related impairment, co-occurring psychiatric symptoms, and quality of life.

Group Intervention Description mindfulness-based intervention for tics (MBIT) mindfulness-based intervention for tics (MBIT) This is an 8-week mindfulness-based group intervention delivered via telehealth. It consists of mindfulness and meditative practice, didactics, inquiry, discussion and weekly therapeutic exercises and assignments (i.e., homework). psychoeducation with relaxation and supportive therapy (PRST) psychoeducation with relaxation and supportive therapy (PRST) This is an 8-week educational and supportive therapy group intervention delivered via telehealth. It consists of psychoeducation, relaxation, discussion, and weekly therapeutic exercises and assignments (i.e., homework).
- Primary Outcome Measures
Name Time Method Yale Global Tic Severity Scale (YGTSS) Total Tic Severity Score Screen, Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) The YGTSS is a clinician-administered measure of tic symptom severity (0-50) and impairment (0-50). Greater scores are reflective of greater severity and/or impairment.
- Secondary Outcome Measures
Name Time Method Attention-Deficit Hyperactivity Rating Scale (ADHD-RS) Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) A self-report measure of ADHD severity that has shown good psychometric properties in TS studies. The total score ranges from 0 to 72, with greater scores indicating greater ADHD severity.
Client Satisfaction Questionnaire Post-treatment (Week 9) An 8-item self-report measure assessing client's satisfaction with treatment services. The total score ranges from 8 to 32. Greater total score corresponds with greater satisfaction with services
Yale-Brown Obsessive Compulsive Scale-II Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) A clinician-administered measure of OCD severity that has shown good psychometric properties. The total score ranges from 0 to 50, with greater total score reflective of greater severity.
Clinical Global Impressions Scales of Severity and Improvement (CGI-S & CGI-I) Screen, Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) In order for a participant to be considered a treatment responder, he or she must receive a score of 1 (not ill or very much improved) or 2 (borderline mentally ill or much improved).
Patient Health Questionnaire-9 (PHQ-9) Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) A self-report measure of depressive symptom severity (range: 0-27), with greater total score reflecting greater depressive severity.
Self Compassion Scale Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) Measure ranges from 26 to 130, with higher scores indicating higher levels of self-compassion
Affective Reactivity Index Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) A 6-item scale of affective reactivity that ranges from 0-12, with higher scores reflective of greater affective reactivity.
Adult Tic Questionnaire (ATQ) Screen, Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) Higher ATQ scores reflect a worse outcome. For each tic present in the past week, its severity score is the sum of its frequency score (0-4, 4 worst, occurring "almost all the time during the day") and its intensity score (0-4, 4 worst). The ATQ severity score is the sum of the severity score for each of up to 27 tics present in the past week. The minimum possible severity score on the ATQ is 0, indicating that no tics were present in the past week. The maximum possible severity score on the ATQ indicates is 216, indicating that a tic of each of the 27 types listed was present in the past week, each with an item severity score of 8 = 4 + 4.
Five Facet Mindfulness Questionnaire (FFMQ) Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) Each item is rated on a 1 to 5 scale with 1=never or very rarely true and 5=very often or always true; responses are summed and then divided by 39 (the number of items). Higher scores on the FFMQ reflects a higher level of mindfulness (a better outcome).
Premonitory Urge to Tic Scale (PUTS) Baseline (Week 0), Mid-treatment (Week 5), Post-treatment (Week 9), 1-month follow-up (Week 13), 3-month follow-up (Week 22), and 6-month follow-up (Week 35) A self-report measure of premonitory urges (range: 0-36), with a greater total score reflective of greater premonitory urges.
