Evaluation of an Online Comprehensive Behavioral Intervention for Tics (CBIT) Therapist Training Program

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.

Tic disorders are a class of childhood-onset neuropsychiatric disorders that occur in 1-3% of the population and often cause significant impairment in physical, social, academic, and interpersonal functioning and reduced quality of life. There is currently no cure for tic disorders, however large-scale randomized controlled trials have shown that a non-drug treatment known as Comprehensive Behavioral Intervention for Tics (CBIT) is more effective than supportive psychotherapy for reducing tics in both 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. Given the need and desire for CBIT among individuals with tic disorders, high demand for therapist trainings, and the lack of therapists adequately trained in CBIT, there is a clear need for innovative ways to train more providers in this evidence-based treatment. To address this gap, the investigators recently developed an innovative online program for training therapists to deliver CBIT (called CBIT-Trainer). This study will test CBIT-Trainer against an intensive in-person therapist training program in a randomized controlled trial. This study will accomplish four aims: (1) to compare CBIT-Trainer to traditional in-person training on therapists' ability to administer CBIT with fidelity, (2) to compare CBIT-Trainer to in-person training on patient outcomes when patients are treated by a CBIT-trained therapist, (3) to identify therapist factors that might improve (or limit) adoption and use of CBIT-Trainer, and (4) to identify therapist factors likely to influence continued use of CBIT after training. These aims will be tested using an effectiveness-implementation hybrid randomized controlled trial comparing CBIT-Trainer (online therapist training) to the Tourette Association of America's Behavior Therapy Training Institute (in-person therapist training), which is the current gold-standard for training CBIT therapists. Therapist-patient dyads will be recruited to participate. The primary therapist outcome will be therapists' skill in delivering CBIT in a standardized role-play, which will be assessed at post-training (Week 0), after administering CBIT with a patient (Week 10), and at 6-month follow-up (Week 24). The primary patient outcome will be overall clinical improvement, which will be assessed at pre-treatment (Week 0), post-treatment (Week 10), and 6-month follow up (Week 24). Secondary therapist outcomes that will be assessed include changes in knowledge of tic disorders and CBIT; changes in comfort and self-efficacy in delivering CBIT; adherence to the CBIT protocol when treating a patient with tics; attitudes toward evidence-based practice and CBIT; and therapists' ratings of the acceptability, appropriateness, and feasibility of the training. Secondary patient outcomes that will be assessed include changes in motor and/or vocal tic severity; changes in overall psychological/behavioral, physical, and social functioning; and satisfaction with the treatment received.

Eligibility Criteria:
This study will recruit therapist-patient dyads who meet the criteria below:

Therapist Inclusion Criteria:

2. Professionally licensed or certified to practice in their area of speciality.
3. Attest that providing comprehensive behavioral intervention for tics (CBIT) to treat children and/or adults with tic disorders falls within their scope of practice according to state licensing laws and regulations in the therapist's jurisdiction.

5. Have access to a secure personal computer with high-speed internet access.
6. Speaks fluent English.
7. Has identified, or is willing to try to identify, at least 1 child or adult patient with a tic disorder who meets the patient inclusion criteria and who might be willing to participate in the study as a member of the therapist-patient dyad, and for whom the therapist is licensed or certified to treat with CBIT according to state licensing laws and regulations in the therapist's jurisdiction.
8. Is willing to be randomly assigned to training condition.
9. Is willing, able, and has the necessary resources to travel to, and attend, one of several in-person training sites if assigned to the in-person training condition.

Therapist Exclusion Criteria:

(1) Therapist is a first, second, or third degree biological relative, stepparent, or legal guardian of the study-matched patient.

Patient Inclusion Criteria:

1. 7 years of age or older (with consenting adult for minors).
2. Self- or parent-reported diagnosis of a tic disorder (e.g., provisional tic disorder, persistent motor/vocal tic disorder, or Tourette's disorder) issued by a qualified professional.
3. Currently engages in at least one motor and/or vocal tic multiple times per day.
4. Patient (and consenting adult for minors) speaks fluent English.
5. Access to a private computer with high-speed internet access.

Patient Exclusion Criteria:

1. Patients will be excluded if the study team is unable to identify and enroll a patient-matched therapist who meets the therapist inclusion criteria.
2. Patient is a first, second, or third degree biological relative of the study-matched therapist or if the study-matched therapist is the patient's legal guardian.
3. Any serious psychiatric or neurological condition that requires more immediate intervention or would interfere with study participation, based on the assessment of the treating therapist or the study investigators.
