Modeling Tic Change During Behavior Therapy for Tics
- Conditions
- Chronic Tic Disorder
- Interventions
- Behavioral: CBIT
- Registration Number

- University of Minnesota
- Brief Summary
Chronic tics are a disabling neuropsychiatric symptom associated with multiple child-onset mental disorders. Chronic tics 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 of Tourette Syndrome (TS) and Persistent Motor/Vocal Tic Disorders.
CBIT is a manualized treatment focused on increasing tic controllability. Its core procedure is competing response training (CRT), in which patients learn to inhibit tics by learning and applying a competing motor action to one tic at a time. CBIT is recommended as a first-line treatment relative to medications and other therapies. However, only 52% of children and 38% of adults show clinically meaningful tic improvement. Large randomized trials have demonstrated the superiority of CBIT over supportive therapy in child and adult patients, and meta-analysis shows comparable effect sizes for CBIT and medication. Although increasing tic controllability is the primary goal of CBIT, tic controllability nor its correlates have been examined longitudinally during the intervention.
The overall objective of this study is to use fine-grained data collection strategies to identify patterns in tic controllability and other relevant related variables that are associated with treatment response to CBIT. Participants with chronic tics will complete a manualized course of 8-session CBIT. Behavioral, psychosocial, and global functioning will be assessed longitudinally to examine predictors and correlates of response. CBIT sessions will be video recorded.

- Primary Outcome Measures
Name Time Method Clinical Global Impressions (CGI) Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Clinician, patient, parent-rated global measure of illness severity and improvement
Sheehan Disability scale Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Self and parent measure of functional impairment
Parent/Adult Tic Questionnaire Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Adult-self or parent-report measure of tic symptoms and severity
Tic Severity Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Yale Global Tic Severity Scale (YGTSS) will be used, which is Gold-standard, clinician administered tic severity scale. It includes symptom checklist of specific tic types YGTSS ranges from 0-50, higher scores are more severe tic symptoms
Caregiver Strain Questionnaire Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Measure of strain experienced by caregivers and family of youth with health/emotional challenges
Behavior Rating Inventory of Executive Function Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Self and parent-rated measure of impairment of executive function
Ask Suicide-Screening Questions (ASQ) Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Clinician-administered screen of suicidality
Child Attitudes Toward Illness Scale (CATIS) Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Self-report measure of favorably or unfavorably adolescent feels about having a chronic illness
Rosenberg Self-Esteem Scale Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Self-report measure of adolescent feelings of self-esteem and self-worth
- Secondary Outcome Measures
Name Time Method Tic Suppression Task Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Direct observation measure of tic suppression ability
Stop signal task Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Computerized task measuring ability to inhibit prepotent motor responses. This task is optional.
Premonitory Urge for Tics Scale Baseline, post-treatment (week 8-10), follow up 1 (week 4-6 post-treatment) and follow up 2 (week 12-14) post-treatment) Self-report measure of intensity of urges to tic
