The present study aimed to determine the effectiveness of Mindfulness-Based Stress Reduction (MBSR) on aggression and self-esteem with the mediation of emotional self-regulation in adolescents with emotion dysregulation. This research was a quasi-experimental study with a pretest-posttest control group design. The statistical population included all female adolescents aged 13 to 18 years with emotion dysregulation who referred to counseling centers in Tehran in 2025. Among them, 30 individuals were selected through purposive sampling and randomly assigned to an experimental group (n=15) and a control group (n=15). The experimental group received eight 90-minute sessions of MBSR training, while the control group received no intervention. Research instruments included the Ahvaz Aggression Questionnaire, Rosenberg Self-Esteem Scale, and the Emotion Regulation Questionnaire (Gross & John). Data were analyzed using multivariate analysis of covariance and path analysis. The results showed that MBSR training significantly reduced aggression and increased self-esteem in adolescents of the experimental group. Furthermore, the results of path analysis confirmed that emotional self-regulation played a significant mediating role in the relationship between mindfulness with aggression and self-esteem. Based on the findings of this study, MBSR, through enhancing emotional self-regulation abilities, can be used as an effective intervention method for reducing aggression and increasing self-esteem in adolescents with emotion dysregulation.
