Overview

This study hopes to explore whether the changes in rumination exhibited in behavioral experiments mediates the effects of mindfulness intervention on alleviating emotional distress

In recent years, mindfulness-based interventions (MBIs) have seen extensive application in both clinical and non-clinical settings. Studies show that mindfulness training improves emotional regulation and processing, contributing to better emotional health. MBIs have proven effective in reducing anxiety and depression among patients with conditions like multiple sclerosis, enhancing personal well-being, and alleviating chronic pain. Given the mounting evidence supporting its benefits, MBIs have become widely adopted across various settings. Nonetheless, the precise mechanisms through which mindfulness alleviates emotional distress remain poorly understood. Rumination, a transdiagnostic process, plays a critical role in the development and persistence of emotional distress. Empirical evidence supports the effectiveness of MBIs in reducing rumination. However, the role of rumination in mediating the effects of MBIs on emotional distress remains inconsistent across studies. Kazdin (2007, 2009) outlined criteria for evaluating mechanisms and mediators, yet existing studies lack sufficient evidence to meet these standards. This study aims to explore the mechanistic role of rumination using behavioral experiments, focusing on the consistency criterion
