Previous research investigating the use of Mindfulness as an intervention has generally taken a quantitative approach, focusing on outcomes rather than processes. The purpose of this research was to develop an understanding of how and why Mindfulness training might influence young people. The study explored the changes in narratives that occur in young people following a Mindfulness intervention, in order to provide an understanding of how such an intervention might facilitate change. Five participants experiencing behavioural difficulties in school (n = 5, aged 11 to 14) took part in the "Mindfulness for Schools" intervention. Two of these participants were interviewed using a semi-structured interview schedule prior to and after the intervention. Interviews were analysed using a multi-faceted, staged approach to narrative analysis. Findings are discussed in terms of participants' changes in sense of self, self-compassion, use of Mindfulness language and non-judgemental awareness. Potential implications for the practice of educational psychologists (EPs) and suggestions for future research are discussed.
