What is the primary hypothesis regarding how MBCT impacts depressed patients, and how will this study investigate that hypothesis?
The prevailing hypothesis about how MBCT works in depressed patients is that it boosts body awareness in the moment, known as interoception. This heightened awareness of physical sensations can help participants become more present and break the cycle of self-rumination. Desbordes' study aims to test this hypothesis by examining whether taking an MBCT course leads to changes in brain networks responsible for interoception and rumination. The researchers will monitor these networks during fMRI scans, specifically engaging them through tasks such as heartbeat focus and reflection on negative self-chatter. By comparing pre and post-MBCT brain activity, the study aims to determine whether MBCT truly influences interoception and rumination in depressed patients.
