Adolescent prisoners in Senegal often face significant psychological stress due to their environment and circumstances. Mindfulness-Based Stress Reduction (MBSR) programmes have been introduced as a potential intervention to mitigate these challenges. Participants were recruited from two prisons. Data was collected through pre- and post-programme assessments using standardised measures designed to assess stress levels and mental well-being. A notable reduction of 20% in reported anxiety symptoms among participants who completed the MBSR programme compared to those who did not. The findings suggest that MBSR programmes can be effective in improving psychological health outcomes for adolescent prisoners, warranting further investigation and implementation. Future studies should explore long-term effects of these interventions and consider integrating mindfulness practices into broader rehabilitation strategies.
