An interventional study of Cognitive behavioral therapy (CBT) in Obsessive Compulsive Disorder, Body Dysmorphic Disorder and Tourette Syndrome, sponsored by Massachusetts General Hospital. Active, not recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-02-23.

To examine the effectiveness and clinical care outcomes of cognitive-behavioral therapy interventions at Massachusetts General Hospital (MGH).
Cognitive behavioral interventions are the most widely studied and evidenced-based psychosocial treatment approaches for mental health and health related behavioral problems. Despite their documented efficacy, there is a scarcity of licensed mental health professionals who are available to treat patients with problems that would be amenable to Cognitive Behavioral Therapy (CBT). While CBT interventions have a strong base in terms of efficacy in randomized trials, effectiveness and dissemination studies are lacking in comparison, and hence, these interventions are not reaching the patients in most need of services. Complicating the problem further, insurance companies typically do not reimburse for services provided by trainees who are not licensed. This is a public mental health problem because it limits the degree to which CBT clinicians can be trained to deliver these treatments, and a particular problem at MGH because referring providers do not have a place to send their patient for CBT services, as trainees constitute a large portion of clinical staff. To address this issue, the current study seeks to document outcomes of CBT interventions delivered by credentialed but not licensed trainees. This information can be used to guide policy and reimbursement guidelines for trainees, as well as promote the ability to disseminate efficacious interventions. Information gained from this project will be used to provide feedback to insurance companies, licensing boards, and mental health community stakeholders regarding decision making re: reimbursement for care provided by supervised trainees. Additionally, this may be used as a pilot study for a comparative effectiveness study comparing trainees to licensed staff psychologists.

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

Behavioral: Cognitive behavioral therapy (CBT)
Participants enrolled in this arm of this study will be treated by the behavioral medicine interns with cognitive behavioral therapy focused on both their general health concerns and mental health concerns.
Behavioral: Cognitive behavioral therapy (CBT)
The participant will then undergo a structured clinical interview with a supervised psychology intern/fellow, which will take approximately 1-3 hours over the course of 1-3 sessions. The initial assessment will be followed by up to 24 sessions of cognitive behavioral therapy tailored to their particular diagnosis (most diagnoses/problems require approximately 12 sessions, some require fewer, others require more). The length of treatment will depend on the primary diagnosis/ problem and the complexity and severity of the case. The clinician and patient will agree on a treatment plan after the initial evaluation, targeting a particular mental health or health related behavioral problem with Cognitive Behavioral Therapy. This treatment plan will include an agreed upon number of treatment sessions (up to 24).

The Schwartz Outcome Scale (SOS-10)
The Schwartz Outcome Scale (SOS-10) is designed to measure a broad domain of psychological health. It appears to be sensitive to change with treatment. So, we will be measuring whether the total score of this scale changes throughout treatment, i.e., whether the CBT interventions tend to improve psychological health.
Time frame: at baseline, and at visits 1 through 24, which will occur approximately 1 week apart.
The record gives a start of Jan 2010, a primary completion of Jan 2027 and a completion of Jan 2027. It does not say whether these dates are actual or estimated.
