This thesis is submitted to the University of Birmingham for the degree of Doctor of Forensic Clinical Psychology (ForenClinPsyD) and contains three chapters. The first chapter is a systematic literature review exploring the attitudes and experiences of prison staff working with prisoners who engage in self-harming behaviour. The second chapter is an empirical study, which adopted qualitative methodology to explore the experiences of UK prison officers working with adult male prisoners who self-harm, and the subsequent impact on psychological well-being. The final chapter comprises two press release documents, which provide an accessible summary of both the literature review and empirical research.
