How CBIT works.
Comprehensive Behavioral Intervention for Tics is a manualized, evidence-based therapy developed for Tourette syndrome and persistent tic disorders. It is typically delivered in 8 to 10 weekly sessions.
The premonitory urge
Most tics are preceded by an uncomfortable physical sensation — a tension, itch, or pressure — known as the premonitory urge. The tic temporarily relieves this sensation, which reinforces the cycle. CBIT interrupts this loop.
Habit reversal training
At the core of CBIT is habit reversal: building acute awareness of urges, then performing a competing response — a voluntary behavior physically incompatible with the tic — until the urge fades. Over time, the brain learns that the urge can pass without the tic.
Function-based assessment
The therapist works with the patient (and often family) to map out the environments, routines, and stressors that worsen tics. Together they restructure the day to reduce triggers and reinforce calmer patterns.
Typical protocol
- •Sessions 1–2: Psychoeducation and tic hierarchy
- •Sessions 3–6: Awareness + competing response training (one tic at a time)
- •Sessions 7–8: Function-based interventions and relaxation
- •Sessions 9–10: Generalization, relapse prevention, booster planning
