Offender personality disorder pathway: the impact of case consultation and formulation with probation staff

The latest government policies for personality disordered offenders emphasise the importance of a formulation-based approach to rehabilitation and pathway planning. However, research into forensic case formulation is limited. This paper examines the impact of consultation and formulation, on probation staff working with personality disordered offenders. Staff rated their knowledge, confidence, motivation, and understanding (of offenders), and satisfaction with management plans at three stages: pre-consultation, post-consultation and after receiving a written formulation. The analyses revealed that ratings on all variables examined increased after attending a consultation meeting, with no additional increase in scores following receipt of the formulation letter. The findings provide evidence that consultation has a range of benefits for probation staff, and offer support for the current model of joint-agency working. Further research is needed to clarify the benefits of providing written formulations after consultations, and to explore what features of a formulation are most useful to probation staff.
