Exercise-priming of CBT for Depression: the CBT+ Trial
What this study is about
This study investigates the effects of intentionally sequencing aerobic exercise immediately prior to cognitive behavioral therapy (CBT) to determine its effects on mechanisms of CBT (i.e., working alliance, behavioral activation).
View original scientific description
This study investigates the effects of intentionally sequencing aerobic exercise immediately prior to cognitive behavioral therapy (CBT) to determine its effects on mechanisms of CBT (i.e., working alliance, behavioral activation). To assess the utility of this treatment augmentation, investigators will conduct a randomized controlled trial involving 100 adults with Major Depressive Disorder who will watch a nature documentary while either resting quietly ( 'CalmCBT') or exercising at a moderate intensity ('ActiveCBT') immediately prior to 8 weekly sessions of CBT.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- a diagnosis of DSM-5 (Diagnostic and Statistical Manual of Mental Disorders-5) MDD, confirmed via Structured Clinical Interview for DSM-5 (SCID)
- current depressive symptoms of at least mild severity defined by a Hamilton Rating Scale of Depression (using the GRID-HAMD) score greater than or equal to 8
- EITHER not currently take any mental health medications or use other mental health treatment (e.g., behavioral, psychological) OR be on a stable mental health medication and/or treatment regimen for the past 8 weeks, and encouraged to maintain that regimen for the duration of the 8 week intervention period
- willing and safe to perform exercise based on responses on the Physical Activity Readiness Questionnaire (rules out contraindications to exercise)
- reported being CBT-naïve (as defined by never undergoing structured CBT).
Exclusion criteria
- reporting being currently pregnant, nursing, or planning to become pregnant during the study
- being diagnosed with current Substance Use Disorder, via the SCID
- being diagnosed with lifetime or current Psychosis, Mania, or Bipolar Disorder, via the SCID
- having class III+ obesity (BMI greater than or equal to 40)
- active suicidal ideation with specific plan and intent ('5' score on Suicidal Ideation from Columbia Suicide Severity Rating Scale \[C-SSRS\])

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
