What this trial studies

This randomized controlled trial aims to investigate the dose-response effects of mindfulness meditation on well-being in healthy adults with little to no prior meditation experience. Participants will be assigned to one of four groups receiving varying durations of daily meditation practice—10, 20, or 30 minutes, or a minimal dose of 3-4 minutes—over a 28-day period. The study will assess changes in well-being through self-reported measures at multiple time points, while also monitoring participant engagement and adherence to the meditation regimen. The goal is to determine whether longer meditation sessions lead to greater improvements in psychological well-being.

Who should consider this trial

Good fit: Ideal candidates are healthy adults residing in Australia with minimal prior experience in meditation.

Not a fit: Patients with severe anxiety or depression symptoms may not benefit unless they are receiving ongoing treatment for their conditions.

Why it matters

Potential benefit: If successful, this study could provide insights into optimal meditation practices that enhance well-being and mental health.

How similar studies have performed: Previous studies have shown positive effects of mindfulness meditation on well-being, but this specific dose-response approach is relatively novel.
