National Demonstration Site


The Trust developed the Personality Disorder Service so that it could be embedded within front-line services. Its aim is to create a psychologically-minded approach to all treatment interventions for people with a Personality Disorder. This involves locally-designed training, supervision, advice and consultancy across inpatient and community services.

Primary and Secondary Care Psychological Therapies services are now equipped to work with people who have traits of Personality Disorders, which makes the Trust is one of only a very few Mental Health Trusts able to work with some consistency across both Primary and Secondary Care Services. 


Becoming a Demonstration Site meant national recognition of the achievements Somerset Partnership made in this area and was an opportunity to share our good practice with other Trusts and organisations in order to improve treatment and care pathways in other areas of the country.

It has also lead to improvements for people in accessing high quality and appropriate Talking Therapies and interventions that are psychologically informed for people with Personality Disorder or Personality Disorder traits, at any point along their whole care pathway.
