Mindful Self-Compassion Smartphone Intervention for Worker Mental Health in Japan: Protocol for a Randomized Controlled Trial.

JMIR Research Protocols July 15, 2024 Takumu Kurosawa, Koichiro Adachi, Ryu Takizawa 6 citations

A randomized controlled trial protocol will test whether brief guided mindfulness meditation or self-compassion meditation delivered by a smartphone app improves mental health and work performance among Japanese employees working more than 20 hours per week, aged 18 to 54, not on leave, and without a current mental disorder diagnosis. The trial will enroll 200 participants, assigning them to a self-compassion meditation course, a mindfulness meditation course, or a waitlist group. Daily guided sessions lasting 6 to 12 minutes over 4 weeks are planned. Primary outcomes are psychological distress and job performance; secondary outcomes include well-being, work engagement, and creativity. Recruitment began December 2022, and as of September 2023, 375 participants have been enrolled; intervention and data collection completed in October 2023.

Gender differences in the influence of app-based mindfulness meditation on emotion regulation: a randomised controlled trial.

Scientific Reports April 6, 2026 Koichiro Adachi, Takumu Kurosawa, Ryu Takizawa

In a randomized controlled trial with 300 Japanese workers, a four-week app-based mindfulness intervention including breathing, body-scan, loving-kindness, and open-monitoring meditations was compared to a waitlist. Women who completed the intervention showed greater cognitive flexibility and reduced angry reactions, while men showed no significant changes in these measures. The gender differences did not survive correction for multiple testing, so the findings should be interpreted cautiously. The results tentatively suggest that brief online mindfulness programs may benefit cognitive flexibility and anger regulation differently for women and men, highlighting the potential value of personalized digital mental health interventions.
