ABSTRACT This study evaluates the effectiveness of an 8‐week Mindfulness‐Based Stress Reduction (MBSR) intervention in reducing social media addiction among 22 adolescents. The program incorporated techniques such as body scan, sitting meditation, STOP, and RAIN meditation. Results indicated a significant reduction in social media addiction scores ( p < 0.001, d = 1.68) and an increase in mindfulness levels ( p < 0.001, d = 0.85). Specific dimensions, including mood modification, escape, and relapse, showed marked improvement, whereas withdrawal, deception, and conflict exhibited no notable changes. These findings underscore MBSR as a promising approach for addressing behavioral addictions and enhancing emotional regulation.
