Mindfulness indicates a state of mind, connected with attention and awareness that can be developed and cultivated through meditation.The research hypothesis foresees that the mindfulness attitude significantly correlates with the psychological variables considered: anger, anxiety, depression and feelings towards oneself (self-hatred, inadequacy of the self and self-forgiveness). The aim of this research was to highlight the relationship between mindfulness attitude and previous constructions in a sample of italian teenagers.The sample includes 867 subjects, aged between 13 and 20, from the region of Lazio (Rieti and Rome). The participants compiled, under supervision, a battery of tests consisting of self-report questionnaires. To evaluate the psychological dimensions of our interest, we used four measures: CAMS-R, CDI, STAI-Y Trait, STAXI C/A, FSCRS.The study highlighted significantly a positive correlations between high mindfulness disposition and psychological well-being. Specifically, the study showed that adolescents with a high mindfulness disposition are less depressed, less anxious and angry and they have a higher ability to forgive themselves.The mindfulness attitude is a tendency that individuals can present to a greater or lesser extent, regardless of the practice of mindfulness. The data obtained from this study support the prospective for further investigations that could lead to improvements in terms of psychological well-being.
