Mindfulness for Emotional Distress: An EEG Study

Summary

This is a randomized controlled trial examining the efficacy and neural mechanisms of a standardized Mindfulness Intervention for Emotional Distress (MIED) in adults with subclinical emotional distress. One hundred and sixty participants will be randomly assigned to either an 8-week MIED program or an 8-week Progressive Muscle Relaxation (PMR) active control. The primary aim is to evaluate whether MIED reduces anxiety symptoms and reshapes multilevel emotional processing as measured by multimodal EEG (resting-state FAA/theta, Fast Periodic Visual Stimulation, and event-related potentials). Assessments occur at baseline (T1), post-intervention (T2), and 1-month follow-up.
