The OPD pathway is a set of psychologically-informed services operating across criminal justice and health, underpinned by a set of principles and quality standards. Using evidence-based relational and environmental approaches, it aims to reduce risk associated with serious reoffending and improve mental health within a high-risk, high-harm cohort likely to meet the clinical threshold for a diagnosis of ‘personality disorder’.

The OPD pathway is a jointly funded partnership between His Majesty’s Prison and Probation Service and NHS England.
