About this trial
Tourette Syndrome and Persistent Motor/Vocal Tic Disorder affect 1-3% of youth and can be associated with impaired functioning, emotional and behavioral problems, physical pain, diminished quality of life, and peer victimization. Chronic tics are the primary symptom. Comprehensive Behavioral Intervention for Tics (CBIT) is a manualized treatment focused on tic management skills. During the core CBIT procedure, competing response training, patients learn to inhibit tics by engaging in a competing motor action. The overall objective of this study is to identify bio-behavioral predictors and correlates of response and the most potent aspects of CBIT. Participants with chronic tics will complete a manualized course of 8-session CBIT. Neural, behavioral, psychosocial, and global functioning will be assessed longitudinally to examine predictors and correlates of response. CBIT sessions will be video recorded. CBIT process will be measured with a video-based behavioral coding scheme that will be refined and validated during years 1-2 using archival CBIT videos
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age 10-17 years at time of enrollment.
Current chronic motor and/or vocal tics, defined as tics for at least 1 year without a tic-free period of more than 3 consecutive months. Tics must not be due to a medical condition or the direct physiological effects of a substance.
At least moderate tic severity, defined as a Yale Global Tic Severity Scale total score ≥14 (≥9 for those with motor or vocal tics only).
Full scale IQ greater than 70.
Disqualifiers
Inability to undergo MRI (e.g., metal in body, claustrophobia, orthodontia) and/or EEG.
Active suicidality Previous diagnosis of psychosis, cognitive disability, or structural brain disease that in the investigator opinion would impede participation.
History of seizure disorder
Active substance abuse or dependence.

CBIT
Other interventionParticipants will receive 8 sessions delivered weekly over 10 weeks. All sessions will be video recorded. CBIT components are: 1) Psychoeducation about tics, 2) Functional interventions, 3) Competing response (CR) training, 4) Social support: supportive people (e.g., parent, teacher) , 5) Motivational enhancements, 6) Homework: is assigned each session and typically involves self-monitoring and CR practice. Participants will complete a brief daily homework tracking log in REDCap.

Trial outcomes
Primary outcomes
1
Change in the Total Tic Score on the Yale Global Tic Severity Scale (YGTSS).
The YGTSS is a clinician-rated measure that will be scored by a study Independent Evaluator. For each participant, the severity of tics over the past 1 week will be measured using the sing a data-dYGTSS Total Tic Score, which ranges from ranges from 0-50. Outcome will be reported as change from baseline to post-treatment, change from baseline to 1-month post-treatment, and change from post-treatment to 1-month post-treatment.
Time frame
27 weeksSecondary outcomes
1
Change resting-state fMRI connectivity of the brain
For each participant, signal intensity (unitless measure) will be measured using fMRI during a state of rest. Signal intensity will be measured within established resting-state brain networks. Analysis will compare within- subject change in signal intensity in these networks from pre- to post treatment; these variables will be entered into multivariate prediction models to identify the relationships between signal intensities and YGTSS Total Tic Scores.
Time frame
27 weeks2
neural, behavioral, and psychosocial changes associated with change in tic severity post-CBIT
A data- driven approach will be used to model longitudinal change across multiple key indices to inform reasons for tic severity reduction while identifying therapeutic targets that could be engaged in future research.
Time frame
27 weeks3
Quality of Life: PROMIS Pediatric Profile-49
Description: For each participant, quality of life will be measured using the PROMIS Pediatric Profile-49 questionnaire. Each item is scored from 1-5, and scores are added together to measure overall quality of life and functioning across specific domains. Scores will be PROMIS scores will be entered into linear mixed models to see which are related to baseline YGTSS and change in baseline to post-treatment YGTSS.
Time frame
27 weeks4
Components of CBIT sessions
Recordings of CBIT session videos will be reviewed to measure the specific components of CBIT that therapists use in units of time (i.e., minutes) and frequency (e.g., number of times the therapist delivers each component across sessions). Generalized linear mixed models will be used to model the association between CBIT components and change on the YGTSS.
