Nottinghamshire Personality Disorder and Development Network (NPDDN)

We provide a community service of individual assessments and group therapy for people with complex personality difficulties. We work with clients who are motivated towards change and who feel able to make use of group therapy. 

Our service users often have longstanding difficulties in relationships, early experiences of trauma, poor early attachments, and a pronounced difficulty in managing overwhelming emotions. Not everyone who uses our service has a diagnosis of personality disorder, but all will have significant issues with personality traits which are:

  • persistant - there all the time
  • pervasive - spread across most areas of their lives
  • problematic - causing difficulty for themselves and others

We do not routinely offer care-coordination, but work closely with those services that do. We do not prescribe medication.

NPDDN provides both psycho-education groups, and Mentalization based groups (recommended by National Institute of Care and Excellent [NICE]). These vary in length from 12 weeks to 1 year. We provide group therapy, as it has been proven to work with this client group. Clients benefit from developing appropriate relationships with others who have similar experiences to themselves.

One of the groups, based in Nottingham City, is aimed specifically at young people who have emerging personality difficulties which are of a far greater degree and significance to those of most teenagers and young adults.

The service covers Nottingham City and Nottinghamshire County. Services are offered in Nottingham City, Mansfield, Worksop and Newark.
