A classifier combining EEG and respiration signals can distinguish between meditation and control conditions with 85% accuracy in older novice meditators after a 6-week mindfulness meditation intervention. Using only EEG signals achieved 78% accuracy. The classifier, based on spectral and phase analysis, may serve as an objective marker for meditation ability and could quantify meditation depth and experience in future research.
Law enforcement officers face high stress that harms mental health and can lead to aggression and excessive force. A multi-site, randomized, single-blind clinical feasibility trial tested mindfulness-based resilience training (MBRT) against stress management education and a no-intervention control. The study aimed to refine protocols for a future full-scale trial. Recruitment, retention, and acceptability of MBRT were high, and assessment and intervention protocols were delivered with fidelity. Several physiological and self-report measures showed responsiveness to change. These results prepare for a larger trial testing whether MBRT improves officer health and resilience and reduces aggression and excessive use of force, benefiting communities.
