Effects of a 30-Day Online Sound Healing Intervention on Stress, Anxiety, and Spirituality: A Repeated Measures Study

This study explored the psychological impact of a structured 30-day online sound healing intervention on anxiety, stress, and spirituality among adults. Thirty participants engaged in daily practices including Hari Om chanting, Nāda Yoga meditation, and self-healing with singing bowls. A repeated measures design was used, and participants completed the Beck Anxiety Inventory, Perceived Stress Scale (PSS), and the Spirituality Scale by Dr. Colleen Delaney both before and after the intervention. Data were analyzed using repeated measures MANOVA and follow-up univariate tests in JAMOVI and Python. While multivariate results approached significance, univariate analysis revealed a statistically significant reduction in stress (p = .027), and directional improvements in anxiety and spirituality. These findings suggest that sustained engagement in sound-based practices may be effective in promoting stress relief and holistic well-being, supporting the integration of vibrational healing techniques into wellness programs.
