Personality difficulties provide challenges to offender management, particularly in regard to risk and diagnosis. No provisions exist for identifying personality disturbance in probation services, despite a political emphasis on the need for specialist knowledge of this group in the criminal justice system. This article reports on a pilot project where mental health professionals collaborated with probation services to develop methods of identifying personality disturbance in a London sample. There was a disproportionately large ratio of Black/Black British individuals identified in this study. There was a high prevalence of personality problems in probation caseloads. Different sampling methods identified separate groups of high risk personality disturbed offenders. All individuals identified carried a high risk of re-offending, based on static risk assessments. Emphasis was given to the importance of using developmental variables to help identify adult personality disturbance. The study discovered

Background A model of psychologically informed offender management for high risk of harm offenders with personality disorder (PD) was piloted, in which NHS psychologists worked alongside London probation staff. Aim The aim of the study was to evaluate the initiatives taken to develop probation staff's capability to work effectively with the group of offenders. Method Self-report measures assessing competency for working with PD and team climate were administered to the probation staff (N = 150) at baseline and at 1 year follow-up. At follow-up, qualitative data was also collected from a subset of Public Protection Unit staff (N = 17), evaluating their experience of the project. Results The probation staff significantly improved across a range of generic and forensic PD-related competencies. The largest improvements were found in the Public Protection Unit, which received the highest level of support. There was also a significant improvement in one facet of team climate (team vision). The qualitative findings suggested that the primary areas of skills development were in the participants' understanding of PD and their capacity to identify PD and to develop treatment and management pathways. Conclusions The results provide evidence for the effectiveness of the project model that supports its implementation on a broader scale.Indicates a significant difference between PPU and non-PPU staff at the p < 0.001 level. 91Developing probation staff competency for working with personality disorder
