A pilot investigation of Geometric Meditation-based Cognitive Behavior Therapy (GM-CBT) for a single case of intractable Obsessive-Compulsive Disorder (OCD) found that an eight-week treatment program (90-minute sessions per week) led to a significant reduction in OCD symptoms, anxiety, and depression, along with increased mindfulness skills. A three-month follow-up suggested long-lasting beneficial effects. The authors propose GM-CBT as a holistic CBT approach for OCD.
A single 20-minute session of group mantra-meditation increased salivary immunoglobulin A (s-IgA) and improved positive affect in healthy women. In a controlled pretest-posttest study, 30 women (mean age 44 ± 3 years) from yoga clubs in Shiraz were randomly assigned to meditate or attend a lecture only. Saliva samples and affective state questionnaires were collected at baseline, post-meditation, and one hour later. The meditation group showed significantly higher s-IgA levels and greater positive affect changes than controls. The findings suggest that even brief group mantra-meditation may positively influence immune components and emotional states, offering a low-cost mental-health intervention for settings like nursing homes.
