If left ignored can lead to anxiety-related disorders. Its level is comparatively high in inmates compared to the general public. This research aims to study the relationship between attention, present focus, awareness, acceptance, mindfulness, and anxiety. The purpose of this study was to assess the need to introduce mindfulness techniques or therapies inside the prison premises. The study assessed 100 Indian male inmates of the Delhi prison. Standardised tests were used. The findings say anxiety is significantly negatively correlated with attention, present focus, awareness, acceptance, and mindfulness. Also, mindfulness is significantly positively correlated with attention, present focus, awareness & acceptance.
