There are an increasing, but limited, number of studies investigating the benefits of mindfulness interventions for people experiencing psychosis. To our knowledge, changes following mindfulness for psychosis have not yet been explored from a personal construct perspective. This study had two main aims: (i) to explore changes in the way a person construes their self, others and their experience of psychosis following a Mindfulness‐Based Cognitive Therapy (MBCT) group; and (ii) to replicate the findings of other studies exploring the feasibility and potential benefits of MBCT for psychosis. Sixteen participants, with experience of psychosis, completed an 8‐week MBCT group. Participants completed pre‐group and post‐group assessments including a repertory grid, in addition to a range of outcome measures. There was some evidence of changes in construing following MBCT, with changes in the way participants viewed their ideal self and recovered self, and an indication of increased self‐understanding. Improvements were found in participants' self‐reported ability to act with awareness and in recovery. This study demonstrates the feasibility and potential benefits of MBCT groups for people experiencing psychosis. Furthermore, it provides some evidence of changes in construal following MBCT that warrant further exploration. Large‐scale controlled trials of MBCT for psychosis are needed, as well as studies investigating the mechanisms of change. Copyright © 2015 John Wiley & Sons, Ltd. Key Practitioner Message MBCT may contribute to change in individuals' perceptions and increase self‐understanding. The study highlights the importance of measuring change in recovery following MBCT. Findings support the need for person‐centred approaches to assessment and monitoring of personal change following therapy. Similar studies using a control group are needed in order to identify whether the changes found are attributable to participation in an MBCT group. Copyright © 2015 John Wiley & Sons, Ltd.
