Purpose - The purpose of this paper is to explore the perspectives of prisoners and prison staff in relation to mental wellbeing and the negotiation of barriers to accessing and providing support. This small-scale study includes the experiences of 11 prison staff and 9 prisoners within a Category D male prison. Design/Methodology/approach - A focus group was conducted with the prisoners and interviews with prison staff. Thematic analysis identified three core themes: “context enabling factors”, “barriers to accessing support for mental wellbeing” and “peer support roles”. Findings – Prisoners conveyed a reluctance in reporting mental health issues due to the fear of being transferred to closed conditions. All staff indicated the benefits of peer support roles. Research limitations/implications - Further research is required on a wider scale, as it is acknowledged that the findings of this study are from one prison and may not apply to other settings. Although there are barriers that may impact the reporting of mental wellbeing issues, there may be small relational steps that can be taken to address these. Originality/Value - Few studies exist that explore the nuances and barriers within open prisons, perhaps due to the overwhelming need within closed conditions. A context specific approach considering early prevention strategies to support a safer prison system and successful rehabilitation are explored. The combination of prisoner and staff experiences is of value to both academia and policymakers.
