A proposed randomized controlled trial will test whether longer daily mindfulness meditation sessions produce greater improvements in well-being. Healthy adults aged 18–65 will be assigned to 4-week online courses with 10, 20, or 30 minutes of daily practice, or a 4-minute control condition. The primary outcome is psychological well-being, measured at baseline, midintervention, postintervention, and one-month follow-up. The trial aims to enroll at least 688 participants; as of end of 2024, 70 eligible participants were enrolled. Results are expected by March 2026.
A planned online mindfulness course for healthy adults aged 18–65 years will test whether longer daily meditation practice (10, 20, or 30 minutes) produces greater improvements in well-being and other psychological outcomes than a short control practice (4 minutes). The study aims to enroll at least 688 participants, but recruitment has been slow and affected by fraudulent entries; by the end of 2024 only 70 eligible participants had enrolled. The trial will measure well-being, distress, anxiety, depression, and other factors at several time points, with results expected by March 2026.
