Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
250

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients presenting to the Behavioral Medicine Service are generally individuals with an acute or chronic medical condition or medically related concern with or without an associated DSM-IV psychiatric disorder, as well as adult patients who require assistance with changing health or health-risk behaviors. Patients presenting to the OCD program typically have obsessive compulsive disorder, body dysmorphic disorder, Tourette syndrome, compulsive skin picking, or trichotillomania. Patients presenting to the general CBT program typically have panic disorder, social phobia, generalized anxiety disorder, depression, specific phobia, post traumatic stress disorder, attention deficit hyperactivity disorder, or an eating disorder. Patients at any of the programs have an identifiable behavior or behavioral pattern/ mood problem that they would like to change.
  • Age 18 or older
  • Ability to provide informed consent and comply with the study procedures
  • Ability to complete self-report questionnaires (either written hardcopy or computer-based version) with adequate accommodation, if necessary
  • Patients with a PCP at MGH, receiving specialty care at MGH, or employees of MGH.

Exclusion Criteria:

  • Exhibit active suicidality (suicidal ideation with intent or plan) to the point that more intensive treatment (i.e. acute hospitalization) is required.
  • Active untreated and unstable bipolar disorder (i.e. stable bipolar disorder under care of a psychiatrist is allowed).
  • Psychosis.
  • Mental retardation.
  • Any condition that, after the baseline evaluation, is determined to preclude treatment with cognitive behavioral therapy.
  • Received more than 4 sessions of CBT for the target disorder within the past 3 years.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Cognitive Behavioral Therapy
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).
Other Names:
  • CBT
Experimental: Behavioral Medicine with Cognitive Behavioral Therapy
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Schwartz Outcome Scale (SOS-10)
Time Frame: at baseline, and at visits 1 through 24, which will occur approximately 1 week apart.
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.
at baseline, and at visits 1 through 24, which will occur approximately 1 week apart.
