The Offender Personality Disorder (OPD) Pathway programme is a jointly commissioned initiative between NHS England and Improvement and HM Prison & Probation Service aimed at supporting and managing offenders with complex mental health needs. The aim is to provide a network of psychologically informed services for high-risk high-harm offenders guided by detailed case formulation. The aim of this evaluation was to identify how the Pathway was being experienced by offenders within Pathway services and the staff involved in managing them since its implementation, to statistically compare outcomes between individuals referred to OPD services and those not referred, and to identify whether there was evidence of cost-effectiveness of the Pathway and how different elements of the Pathway contribute to cost-effectiveness. It should be noted that the aim of this evaluation was to look at the OPD Pathway as a whole, and was not to identify the contribution of the various OPD Pathway interventions.
