What is the pattern of self-harm and prison rule-breaking behaviour in personality disordered offenders in a high secure prison?

摘要

Purpose - The purpose of this paper is to describe the pattern of self-harm(SH) and proven prison rule-breaking (PRB) behaviour in prisoners receiving treatment for personality disorders (PDs) within a high security prison. Design/methodology/approach - A comparative quantitative case study design supported the understanding of the frequency and pattern of SH and PRB behaviour across two stages of a PD treatment programme for 74 male prisoners. Data obtained from the prison's records were analysed using dependent t-tests, χ~2 test of independence and time-frequency analyses. Findings - Inferential statistics showed that the frequency of SH and PRB behaviour statistically increased across two phases of the PD treatment programme; however, the method of SH or type of PRB behaviour engaged in did not change. Mapping the frequencies of incidents using a time-frequency analysis shows the patterns of both behaviours to be erratic, peaking in the latter phase of treatment, yet the frequency of incidents tended to decline over time. Originality/value - This is the first study to explore SH and PRB behaviours in men across two phases of a PD treatment programme. This study highlights the need for continued psychological support alongside the PD treatment programme with a focus on supporting men in treatment to effectively manage their SH and PRB behaviour.
