Monthly Mood Improvement After Workplace Mindfulness

This randomized controlled pilot trial investigates the effects of a brief workplace mindfulness-based intervention (MBI) on mood among full-time employees in Japan. Twenty-five participants are randomly assigned to either the MBI group or a wait-list control group. The MBI group receives three 90-minute workshops spaced four weeks apart, along with daily home mindfulness practice. Mood is assessed monthly over three months using the Japanese version of the Profile of Mood States 2 (POMS2). The primary outcome is Total Mood Disturbance (TMD). This study is approved by the Ryusei Hospital Institutional Review Board and conducted as a feasibility trial.
