About this study
Official title: The Effects and Mechanisms of MBCT on Depressive Symptoms and Depression Relapse
This research proposal is intended to elucidate the efficacy and mechanisms underlying Mindfulness Based Cognitive Therapy (MBCT) in a population in remission from recurrent Major Depressive Disorder (MDD). The first objective of the study is to replicate previous studies' findings of MBCT's effects on decreasing depressive symptoms and depression relapse rates. However, this proposal aims to make a novel contribution to the literature by using a randomized, controlled design, and comparing the effects of MBCT to an active control condition (ACC). The use of a well-designed ACC will enable us to control for confounding variables such as social support and expected outcomes, thus allowing us to determine whether elements specific to MBCT lead to its salutary effects (Aim 1). Previous MBCT studies have largely relied on self-report measurement methodologies, limiting valid conclusions about the nature of MBCT. Further, few studies have examined the mechanisms underlying effects of MBCT on depressive symptoms and relapse. Theoretical considerations and preliminary empirical evidence suggest emotional, physiological, and cognitive functioning to be promising mechanisms of MBCT. Therefore, the investigators propose to assess each of these potential mechanisms of MBCT using self-report, autonomic physiological, and reaction time tasks (Aim 2). Collectively, these aims are expected to strengthen the evidence base for MBCT while cultivating a scientific model for its effects and mechanisms on decreasing depressive symptoms and depression relapse rates.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Mindfulness Based Cognitive Therapy and Health Enhancement Program in people with Major Depressive Disorder and Recurrent, run by University of Denver at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Depression Relapse (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2014; AzTrials last refreshed its copy on 7 Nov 2026.
