How is the study investigating the potential effects of MBCT on interoception and rumination in depressed patients?
The study being conducted by Desbordes involves functional magnetic resonance imaging (fMRI) scans, which will monitor brain activity before and after an eight-week course in MBCT. Participants will complete two tasks during the scans: one focused on awareness of their bodies through heartbeat focus, a common exercise in mindfulness meditation; and another involving reflection on negative self-chatter, such as "I am such a loser," or "I can't go on." After a series of these comments, participants are asked to stop ruminating on the phrases and the thoughts they trigger. Researchers will measure how quickly subjects can disengage from negative thoughts, which is typically difficult for those with depression. The process will be repeated for a control group that undergoes muscle relaxation training and depression education instead of MBCT. By comparing brain activity in both groups, researchers hope to determine whether MBCT affects the networks responsible for interoception and rumination differently than the control method.
