Tic disorders are a class of childhood-onset neuropsychiatric disorders that occur in 1-3% of the population. Studies have shown that a non-drug treatment known as Comprehensive Behavioral Intervention for Tics (CBIT) is more effective than supportive therapy for reducing tics in children and adults. Although CBIT is now recommended as a first-line intervention for tic disorders, many patients do not have access to CBIT, in part due to a lack of trained therapists. Currently, the only option available for training therapists in CBIT is an intensive, two day, in-person behavior therapy training institute (BTTI). This study will compare the traditional in-person training approach to a recently developed online, self-paced CBIT therapist training program called CBIT-Trainer with regard to (1) therapists' ability to accurately administer CBIT and (2) change in the severity of patients' tic symptoms after being treated by a CBIT-trained therapist.
